On the website https://code.google.com/apis/console I have registered my application, set up generated Client ID: and Client Secret to my app and tried to log in with Google.
Unfortunately, I got the error message:
Error: redirect_uri_mismatch
The redirect URI in the request: http://127.0.0.1:3000/auth/google_oauth2/callback did not match a registered redirect URI
scope=https://www.googleapis.com/auth/userinfo.profile https://www.googleapis.com/auth/userinfo.email
response_type=code
redirect_uri=http://127.0.0.1:3000/auth/google_oauth2/callback
access_type=offline
approval_prompt=force
client_id=generated_id
What does mean this message, and how can I fix it?
I use the gem omniauth-google-oauth2.
The redirect URI (where the response is returned to) has to be registered in the APIs console, and the error is indicating that you haven't done that, or haven't done it correctly.
Go to the console for your project and look under API Access. You should see your client ID & client secret there, along with a list of redirect URIs. If the URI you want isn't listed, click edit settings and add the URI to the list.
EDIT: (From a highly rated comment below) Note that updating the google api console and that change being present can take some time. Generally only a few minutes but sometimes it seems longer.
In my case it was www and non-www URL. Actual site had www URL and the Authorized Redirect URIs in Google Developer Console had non-www URL. Hence, there was mismatch in redirect URI. I solved it by updating Authorized Redirect URIs in Google Developer Console to www URL.
Other common URI mismatch are:
Using http:// in Authorized Redirect URIs and https:// as actual URL, or vice-versa
Using trailing slash (http://example.com/) in Authorized Redirect URIs and not using trailing slash (http://example.com) as actual URL, or vice-versa
Here are the step-by-step screenshots of Google Developer Console so that it would be helpful for those who are getting it difficult to locate the developer console page to update redirect URIs.
Go to https://console.developers.google.com
Select your Project
Click on the menu icon
Click on API Manager menu
Click on Credentials menu. And under OAuth 2.0 Client IDs, you will find your client name. In my case, it is Web Client 1. Click on it and a popup will appear where you can edit Authorized Javascript Origin and Authorized redirect URIs.
Note: The Authorized URI includes all localhost links by default, and any live version needs to include the full path, not just the domain, e.g. https://example.com/path/to/oauth/url
Here is a Google article on creating project and client ID.
If you're using Google+ javascript button, then you have to use postmessage instead of the actual URI. It took me almost the whole day to figure this out since Google's docs do not clearly state it for some reason.
In any flow where you retrieved an authorization code on the client side, such as the GoogleAuth.grantOfflineAccess() API, and now you want to pass the code to your server, redeem it, and store the access and refresh tokens, then you have to use the literal string postmessage instead of the redirect_uri.
For example, building on the snippet in the Ruby doc:
client_secrets = Google::APIClient::ClientSecrets.load('client_secrets.json')
auth_client = client_secrets.to_authorization
auth_client.update!(
:scope => 'profile https://www.googleapis.com/auth/drive.metadata.readonly',
:redirect_uri => 'postmessage' # <---- HERE
)
# Inject user's auth_code here:
auth_client.code = "4/lRCuOXzLMIzqrG4XU9RmWw8k1n3jvUgsI790Hk1s3FI"
tokens = auth_client.fetch_access_token!
# { "access_token"=>..., "expires_in"=>3587, "id_token"=>..., "refresh_token"=>..., "token_type"=>"Bearer"}
The only Google documentation to even mention postmessage is this old Google+ sign-in doc. Here's a screenshot and archive link since G+ is closing and this link will likely go away:
It is absolutely unforgivable that the doc page for Offline Access doesn't mention this. #FacePalm
For my web application i corrected my mistake by writing
instead of : http://localhost:11472/authorize/
type : http://localhost/authorize/
Make sure to check the protocol "http://" or "https://" as google checks protocol as well.
Better to add both URL in the list.
1.you would see an error like this
2.then you should click on request details
after this , you have to copy that url and add this on https://console.cloud.google.com/
go to https://console.cloud.google.com/
click on Menu -> API & Services -> Credentials
you would see a dashboard like this ,click on edit OAuth Client
now in Authorized Javascript Origins and Authorized redirect URLS
add the url that has shown error called redirect_uri_mismatch i.e here it is
http://algorithammer.herokuapp.com , so i have added that in both the places in
Authorized Javascript Origins and Authorized redirect URLS
click on save and wait for 5 min and then try to login again
This seems quite strange and annoying that no "one" solution is there.
for me http://localhost:8000 did not worked out but http://localhost:8000/ worked out.
This answer is same as this Mike's answer, and Jeff's answer, both sets redirect_uri to postmessage on client side. I want to add more about the server side, and also the special circumstance applying to this configuration.
Tech Stack
Backend
Python 3.6
Django 1.11
Django REST Framework 3.9: server as API, not rendering template, not doing much elsewhere.
Django REST Framework JWT 1.11
Django REST Social Auth < 2.1
Frontend
React: 16.8.3, create-react-app version 2.1.5
react-google-login: 5.0.2
The "Code" Flow (Specifically for Google OAuth2)
Summary: React --> request social auth "code" --> request jwt token to acquire "login" status in terms of your own backend server/database.
Frontend (React) uses a "Google sign in button" with responseType="code" to get an authorization code. (it's not token, not access token!)
The google sign in button is from react-google-login mentioned above.
Click on the button will bring up a popup window for user to select account. After user select one and the window closes, you'll get the code from the button's callback function.
Frontend send this to backend server's JWT endpoint.
POST request, with { "provider": "google-oauth2", "code": "your retrieved code here", "redirect_uri": "postmessage" }
For my Django server I use Django REST Framework JWT + Django REST Social Auth. Django receives the code from frontend, verify it with Google's service (done for you). Once verified, it'll send the JWT (the token) back to frontend. Frontend can now harvest the token and store it somewhere.
All of REST_SOCIAL_OAUTH_ABSOLUTE_REDIRECT_URI, REST_SOCIAL_DOMAIN_FROM_ORIGIN and REST_SOCIAL_OAUTH_REDIRECT_URI in Django's settings.py are unnecessary. (They are constants used by Django REST Social Auth) In short, you don't have to setup anything related to redirect url in Django. The "redirect_uri": "postmessage" in React frontend suffice. This makes sense because the social auth work you have to do on your side is all Ajax-style POST request in frontend, not submitting any form whatsoever, so actually no redirection occur by default. That's why the redirect url becomes useless if you're using the code + JWT flow, and the server-side redirect url setting is not taking any effect.
The Django REST Social Auth handles account creation. This means it'll check the google account email/last first name, and see if it match any account in database. If not, it'll create one for you, using the exact email & first last name. But, the username will be something like youremailprefix717e248c5b924d60 if your email is youremailprefix#example.com. It appends some random string to make a unique username. This is the default behavior, I believe you can customize it and feel free to dig into their documentation.
The frontend stores that token and when it has to perform CRUD to the backend server, especially create/delete/update, if you attach the token in your Authorization header and send request to backend, Django backend will now recognize that as a login, i.e. authenticated user. Of course, if your token expire, you have to refresh it by making another request.
Oh my goodness, I've spent more than 6 hours and finally got this right! I believe this is the 1st time I saw this postmessage thing. Anyone working on a Django + DRF + JWT + Social Auth + React combination will definitely crash into this. I can't believe none of the article out there mentions this except answers here. But I really hope this post can save you tons of time if you're using the Django + React stack.
In my case, my credential Application type is "Other". So I can't find Authorized redirect URIs in the credentials page. It seems appears in Application type:"Web application". But you can click the Download JSON button to get the client_secret.json file.
Open the json file, and you can find the parameter like this: "redirect_uris":["urn:ietf:wg:oauth:2.0:oob","http://localhost"]. I choose to use http://localhost and it works fine for me.
When you register your app at https://code.google.com/apis/console and
make a Client ID, you get a chance to specify one or more redirect
URIs. The value of the redirect_uri parameter on your auth URI has to
match one of them exactly.
Checklist:
http or https?
& or &?
trailing slash(/) or open ?
(CMD/CTRL)+F, search for the exact match in the credential page. If
not found then search for the missing one.
Wait until google refreshes it. May happen in each half an hour if you
are changing frequently or it may stay in the pool. For my case it was almost half an hour to take effect.
for me it was because in the 'Authorized redirect URIs' list I've incorrectly put https://developers.google.com/oauthplayground/ instead of https://developers.google.com/oauthplayground (without / at the end).
The redirect url is case sensitive.
In my case I added both:
http://localhost:5023/AuthCallback/IndexAsync
http://localhost:5023/authcallback/indexasync
If you use this tutorial: https://developers.google.com/identity/sign-in/web/server-side-flow then you should use "postmessage".
In GO this fixed the problem:
confg = &oauth2.Config{
RedirectURL: "postmessage",
ClientID: ...,
ClientSecret: ...,
Scopes: ...,
Endpoint: google.Endpoint,
}
beware of the extra / at the end of the url
http://localhost:8000 is different from http://localhost:8000/
It has been answered thoroughly but recently (like, a month ago) Google stopped accepting my URI and it would not worked. I know for a fact it did before because there is a user registered with it.
Anyways, the problem was the regular 400: redirect_uri_mismatch but the only difference was that it was changing from https:// to http://, and Google will not allow you to register http:// redirect URI as they are production publishing status (as opposed to localhost).
The problem was in my callback (I use Passport for auth) and I only did
callbackURL: "/register/google/redirect"
Read docs and they used a full URL, so I changed it to
callbackURL: "https://" + process.env.MY_URL+ "/register/google/redirect"
Added https localhost to my accepted URI so I could test locally, and it started working again.
TL;DR use the full URL so you know where you're redirecting
2015 July 15 - the signin that was working last week with this script on login
<script src="https://apis.google.com/js/platform.js" async defer></script>
stopped working and started causing Error 400 with Error: redirect_uri_mismatch
and in the DETAILS section: redirect_uri=storagerelay://...
i solved it by changing to:
<script src="https://apis.google.com/js/client:platform.js?onload=startApp"></script>
Rails users (from the omniauth-google-oauth2 docs):
Fixing Protocol Mismatch for redirect_uri in Rails
Just set the full_host in OmniAuth based on the Rails.env.
# config/initializers/omniauth.rb
OmniAuth.config.full_host = Rails.env.production? ? 'https://domain.com' : 'http://localhost:3000'
REMEMBER: Do not include the trailing "/"
None of the above solutions worked for me. below did
change authorised Redirect urls to - https://localhost:44377/signin-google
Hope this helps someone.
My problem was that I had http://localhost:3000/ in the address bar and had http://127.0.0.1:3000/ in the console.developers.google.com
Just make sure that you are entering URL and not just a domain.
So instead of:
domain.com
it should be
domain.com/somePathWhereYouHadleYourRedirect
Anyone struggling to find where to set redirect urls in the new console: APIs & Auth -> Credentials -> OAuth 2.0 client IDs -> Click the link to find all your redirect urls
My two cents:
If using the Google_Client library do not forget to update the JSON file on your server after updating the redirect URI's.
I also get This error Error-400: redirect_uri_mismatch
This is not a server or Client side error but you have to only change by checking that you haven't to added / (forward slash) at the end like this
redirecting URL list ❌:
https://developers.google.com/oauthplayground/
Do this only ✅:
https://developers.google.com/oauthplayground
Let me complete #Bazyl's answer: in the message I received, they mentioned the URI
"http://localhost:8080/"
(which of course, seems an internal google configuration). I changed the authorized URI for that one,
"http://localhost:8080/" , and the message didn't appear anymore... And the video got uploaded... The APIS documentation is VERY lame... Every time I have something working with google apis, I simply feel "lucky", but there's a lack of good documentation about it.... :( Yes, I got it working, but I don't yet understand neither why it failed, nor why it worked... There was only ONE place to confirm the URI in the web, and it got copied in the client_secrets.json... I don't get if there's a THIRD place where one should write the same URI... I find nor only the documentation but also the GUI design of Google's api quite lame...
I needed to create a new client ID under APIs & Services -> Credentials -> Create credentials -> OAuth -> Other
Then I downloaded and used the client_secret.json with my command line program that is uploading to my youtube account. I was trying to use a Web App OAuth client ID which was giving me the redirect URI error in browser.
I have frontend app and backend api.
From my backend server I was testing by hitting google api and was facing this error. During my whole time I was wondering of why should I need to give redirect_uri as this is just the backend, for frontend it makes sense.
What I was doing was giving different redirect_uri (though valid) from server (assuming this is just placeholder, it just has only to be registered to google) but my frontend url that created token code was different. So when I was passing this code in my server side testing(for which redirect-uri was different), I was facing this error.
So don't do this mistake. Make sure your frontend redirect_uri is same as your server's as google use it to validate the authenticity.
The main reason for this issue will only come from chrome and chrome handles WWW and non www differently depending on how you entered your URL in the browsers and it searches from google and directly shows the results, so the redirection URL sent is different in a different case
Add all the possible combinations you can find the exact url sent from fiddler , the 400 error pop up will not give you the exact http and www infromation
Try to do these checks:
Bundle ID in console and in your application. I prefer set Bundle ID of application like this "org.peredovik.${PRODUCT_NAME:rfc1034identifier}"
Check if you added URL types at tab Info just type your Bundle ID in Identifier and URL Schemes, role set to Editor
In console at cloud.google.com "APIs & auth" -> "Consent screen" fill form about your application. "Product name" is required field.
Enjoy :)
Backend
I am trying make a JWT cookie based authentication work. I am currently performing the following cookie setting as part of a login route in the backend API.
res.cookie('authCookie', token, {maxAge: 900000, httpOnly: true});
Later when I am auth(ing) any other requests, I am reading off of this cookie and testing it in a passport-jwt strategy.
I have gotten this work in postman - when I perform a login and access a secured route - it works perfectly fine + the cookie is also getting set in postman.
Frontend
Now, I am performing the following call stack in the frontend just to test the working,
axios.post("http://localhost:3001/login", logInParams, config)
.then(result => {
// User is logged in so push them to the respective dashboard
console.log(result);
axios.get("http://localhost:3001/user/profile")
.then(result => {
console.log(result);
})
.catch(err => {
console.log(err);
return;
})
})
.catch(err => {
console.log(err)
return;
});
So basically, I log the user in and that works perfectly fine - I am getting a JSON response as intended, but the call is supposed to set a cookie which it is not and hence the next axios.get call is not returning successfully. Though for some reason I see session cookie and a CSRF cookie. Only this authCookie or the jwt-cookie is not getting set.
Some extra details
I am using cors with default parameters - could this be an error of this? Or is there any changes I have to do with axios? I have seen some answers and being new to MERN I don't really understand them. Does someone know about this or have experienced it and solved it?
Are you running the server from a different port than the one that provides the client (i.e: webpack-dev-server running on localhost:3000 and Express server on localhost:3001)? This looks like a same-site cookie issue. In the latest versions of some browsers such as Chrome cookie setting is being blocked when this one comes from a different origin site. This is due to security concerns; you can learn more about same-site cookies here.
The change made in the browsers is related to the default value they give to a cookie policy property called same-site. The old workaround was treating all the cookies from a different origin as None by default, but last year it changed to consider the same-site policy as Lax when no same-site policy was not explicitly provided by the server. This is a desirable behaviour from the browser because it helps at preventing third party sites making use of the cookie provided by the server, but you can edit it by different ways:
Changing the default same-site policy of your browser settings (the article about same site cookies explains).
Sending a same-site:'None' from the server. Express has a way to do so explaind on its docs. Keep in mind browsers also have a new policy to ignore same-site:'None' when the cookie is not marked as Secure, what demands the use of HTTPS (I guess this behaviour can be edited in your browser settings if you want to check while using HTTP).
Obviously, any strategy that demands the users to change their browser settings is a no-go, so running HTTPS with Secure cookies is mandatory for same-site:'None'.
You always have the approach of making both browser and client same origin, so you won't have any issues at all with same-site (i.e. the Express server returning the index.html of the production build of your client as its main static). I haven't found any way to configure CORS module to have a default same site cookies policy (or its sole use as middleware to change it), likely not its purpose, but you can try by adding a dynamic origin config.
As far as I've seen, Postman does not support the same-site cookie property yet, so that would explain why is it working on Postman but not on the browser.
From the looks of it - it seems to be an issue with how cors works and I am adding the following answer to help anyone else coming across it. Thank me later :)
Server Side
You will have a cors in your server that looks like this,
app.use(cors());
You will have to set credentials to true and set the allowedHeaders and origin as follows,
app.use(cors({
credentials: true,
allowedHeaders: ['Content-Type', 'Authorization'],
origin: ['http://localhost:3000']
}));
This is because normally cookies are not allowed to be set in the browser if the server and the client are in the same port. To handle this the above is required on the server side.
Client Side
We also have to pass the cookies when we are sending the request and to do this with axios just add the following in the index.js of your react app as so,
axios.defaults.withCredentials = true;
I think you should write send('cookies are set') at the end in res.cookie('authCookie', token, {maxAge: 900000, httpOnly: true});
I have a setup which - as far as I can tell - is fairly common nowadays: a backend REST API that lives on its own domain, say myapi.com, and a single page frontend application that is served somewhere else, say myapp.com.
The SPA is a client to the API and the API requires users to authenticate before they can do things.
The backend API is using cookies to store session data for some allowed origins among which myapp.com. This is in order to have a safe bus to transmit and store auth data without having to worry about it client-side.
In Chrome, Opera and Firefox, this works just fine: an API call is made to authenticate the user, Cookies are returned and stored in the browser in order to then be pushed together with the next call.
Safari, on the other hand, does receive the cookies but refuses to store them:
I suspect Safari sees the API domain as a 3rd party cookie domain and therefore blocks the cookies from being stored.
Is this the expected behaviour in Safari? If so, what are some best practices to get around it?
Perpetuating a tradition of answering your own question on this one.
TL;DR this is desired behaviour in Safari. The only way to get around it is to bring the user to a webpage hosted on the API's domain (myapi.com in the question) and set a cookie from there - anything really, you can write a small poem in the cookie if you like.
After this is done, the domain will be "whitelisted" and Safari will be nice to you and set your cookies in any subsequent call, even coming from clients on different domains.
This implies you can keep your authentication logic untouched and just introduce a dumb endpoint that would set a "seed" cookie for you. In my Ruby app this looks as follows:
class ServiceController < ActionController::Base
def seed_cookie
cookies[:s] = {value: 42, expires: 1.week, httponly: true} # value can be anything at all
render plain: "Checking your browser"
end
end
Client side, you might want to check if the browser making the request is Safari and defer your login logic after that ugly popup has been opened:
const doLogin = () => {
if(/^((?!chrome|android).)*safari/i.test(navigator.userAgent)) {
const seedCookie = window.open(`http://myapi.com/seed_cookie`, "s", "width=1, height=1, bottom=0, left=0, toolbar=no, location=no, directories=no, status=no, menubar=no, scrollbars=no, resizable=no, copyhistory=no")
setTimeout(() => {
seedCookie.close();
// your login logic;
}, 500);
} else {
// your login logic;
}
}
UPDATE: The solution above works fine for logging a user in, i.e. it correctly "whitelists" the API domain for the current browser session.
Unfortunately, though, it appears that a user refreshing the page will make the browser reset to the original state where 3rd party cookies for the API domain are blocked.
I found a good way to handle the case of a window refresh is to detect it in javascript upon page load and redirect the user to an API endpoint that does the same as the one above, just to then redirect the user to the original URL they were navigating to (the page being refreshed):
if(performance.navigation.type == 1 && /^((?!chrome|android).)*safari/i.test(navigator.userAgent)) {
window.location.replace(`http://myapi.com/redirect_me`);
}
To complicate things, it turns out Safari won't store cookies if the response's HTTP status is a 30X (redirect). Thereby, a Safari-friendly solution involves setting the cookies and returning a 200 response together with a JS snippet that will handle the redirect within the browser.
In my case, being the backend a Rails app, this is how this endpoint looks like:
def redirect_me
cookies[:s] = {value: 42, expires: 1.week, httponly: true}
render body: "<html><head><script>window.location.replace('#{request.referer}');</script></head></html>", status: 200, content_type: 'text/html'
end
What worked for me (as mentioned by others / in other similar questions too) is to put my Frontend and Backend under same domain, e.g:
frontend.myapp.com
backend.myapp.com
Then both Safari on Mac Monterey and Safari on iOS 15 started to allow set-cookie from backend.myapp.com (with Secure, HttpOnly, SameSite=none) and access them from frontend.myapp.com
