Why is an OPTIONS request sent and can I disable it?

I am trying to call a POST request in ReactJs using Axios, but getting an error. Code:
const payload =
{
device_id: 'ASDACCAS',
device_type: 'Web',
device_version: '1.2',
device_user_id: 'ASDBADKKK1234AS'
}
axios({
method: 'post',
url: 'https://stageapi.myapi.com/v3_2/user/splash',
data: payload,
headers: {
'secret-key': 'mysecretkey',
'Content-Type': 'application/json'
},
})
But this is giving me error:
Failed to load https://stageapi.myapi.com/v3_2/user/splash: Response for preflight does not have HTTP ok status.
Kindly help me whats wrong here. I am new to ReactJS and moving from mobile app development environment. I have been on this for so long, tried every method for axios POST including by appending formdata to body. Still the same.
EDIT:
Also, I am not sure if its something related to CORS. I have installed the the CORS plugin in chrome. Are there any changes that I need to make in API side code? Which is written in php.
When you want to make a post request, you need to stringify body request like this:
axios({
method: 'post',
url: 'https://stageapi.myapi.com/v3_2/user/splash',
data: JSON.stringify(payload),
headers: {
secret-key': 'mysecretkey',
'Content-Type': 'application/json'
},
})
axios.post('https://stageapi.myapi.com/v3_2/user/splash',
payload,
headers: {
'secret-key': 'mysecretkey',
'Content-Type': 'application/json'
}
})
.then((response) => {
console.log(response.data);
});

I've started to build a project using WooComeerce and React.js, but I have one question.
When I try to get the data, for example: "products", received an issue 401 unauthorized..
I've tested my request into Postman/Insomnia and everything is working as expected. I think the problem is coming from the headers part, but for now I can't handle the issue..
Also my response headers are empty!
Here is my code:
const getProducts = async () => {
const response = await fetch(`${process.env.REACT_APP_API_URL}products?consumer_key=${process.env.REACT_APP_API_CONSUMER_KEY}&${process.env.REACT_APP_CONSUMER_SECRED_KEY}`,
{
method: "GET",
mode: "cors",
credentials: "include",
headers: {
"Authorization": `Basic ${process.env.REACT_APP_API_CONSUMER_KEY}`,
"Content-Type": "application/json",
},
}
);
return response;
};
How can i fix that issue?
Note: I'm not using WooCommerce REST API package.
Thank you in advance!
Usually the basic auth string is base64-encoded string username:password. However i see the consumer key being used in the req and the header. Can you please double check your authorization header?
I would like to make post request in redux-saga. My code looks like:
var formdata = new FormData();
formdata.append("points", "a,b");
formdata.append("pid", "someid");
formdata.append("tions", "cses");
formdata.append("exp", "cx");
const ans = yield call(fetch,
'http://localhost:8000/api',
{
method: "POST",
headers: { 'Authorization': 'Token tokenid',
"Content-Type": "application/json",},
body : formdata
});
In Postman it is working fine (selected form-data in body), but in saga, the POST request is not happening at all.
Please suggest where I am doing wrong?
The problem is with your Exceptions on server-side, When you are throwing an error the headers are not set. So what you should do is with CORS Errors only with 400 bad request react fetch request.
Update :- The 400 Bad request has gone away after I added "Content-Type": "application/x-www-form-urlencoded" in the headers and changed the body type accordingly
Example :-
fetch("api/xxx", {
body: "email=test#example.com&password=pw",
headers: {
"Content-Type": "application/x-www-form-urlencoded",
},
method: "post",
}
I've been trying for the whole day to perform a post request using axios in react (I'm trying to get an access_token for a Monzo app). I've followed the instructions here and they work perfectly when trying them out with the httpie command line tool as illustrated on said instructions. However, when I try to use it from within my react app, things go awry. The post request in question using httpie is as follows:
http --form POST "https://api.monzo.com/oauth2/token" \
"grant_type=authorization_code" \
"client_id=my_client_id" \
"client_secret=my_client_secret" \
"redirect_uri=my_redirect_uri" \
"code=my_authorization_code"
and this works as expected and returns a JSON object containing my access_token.
The (problematic) axios command I've been using in my react app is:
axios.post(
"https://api.monzo.com/oauth2/token", {
grant_type: "authorization_code",
client_id: my_client_id,
client_secret: my_client_secret,
redirect_uri: my_redirect_uri,
code: my_authorization_code
})
The error message I'm getting is Failed to load resource: the server responded with a status of 400 ().
I found this very related question, which suggests I add a header specifying Content-Type: application/json so I changed my axios commands to:
axios({
method: "POST",
url: "https://api.monzo.com/oauth2/token",
data: JSON.stringify({
grant_type: "authorization_code",
client_id: my_client_id,
client_secret: my_client_secret,
redirect_uri: my_redirect_uri,
code: my_authorization_code
}),
headers: {
'Content-Type': 'application/json'
}
})
which, unfortunately, gives the exact same error.
Can anybody give me a few pointers on this? I'm very new to networking...thanks!
And as it usually happens with these things, I found the answer shortly after posting the question. Apparently, the 'Content-Type' needs to be sent as 'application/xxx-form-urlencoded' and the data to be transformed accordingly like so:
const queryString = require('query-string')
axios({
method: "POST",
url: "https://api.monzo.com/oauth2/token",
data: queryString.stringify({grant_type: ...}),
headers: {
'Content-Type': 'application/x-www-form-urlencoded'
}
})
I'm quite new with ANGULAR and web development in general and I'm currently working on a web tool. Now I want this tool to send a POST request to a web service but Im encountering a weird bug. Now I have below code in my javascript:
var data_info = { test_id: 'TEST', model_id: 'TEST:TEST_ID' };
//data_info = JSON.stringify(data_info);
var request_json = {
method: 'POST',
url: url,
headers: {
'Content-Type': 'application/json',
'Accept': 'application/json'
},
data: data_info,
cache: false,
};
console.log(request_json);
$http(request_json).then(function successCallback(response) {
// response code here
}
Now this code currently doesn't pass the preflight request check and is always returning a 405. But if I change the line data: data_info in the request JSON into a new key let's say body: data_info it now successfully sends the request and I can confirm that the service is receiving it. I'm not sure what's the issue here and can't figure it out.
change your header to :
headers : {
'Content-Type': 'application/x-www-form-urlencoded;charset=utf-8;'
}
Please try
I am trying to upload a file from React Native to my server. However I am unable to set the 'Content-Type' header to multipart/form-data.
Here's my simple request:
axios({
uri: 'http://localhost:3000',
method: 'POST',
data: formData,
headers: {
Accept: 'application/json',
'Content-Type': 'multipart/form-data'
}
});
I am using the React Native Debugger to monitor Network requests.
When I see my Network request inside the Debugger, I see this:
'Content-Type': 'text/plain;charset=UTF-8'
and the Request Payload is simply [object Object]
User Agent:
Mozilla/5.0 (Macintosh; Intel Mac OS X 10_12_6) AppleWebKit/537.36 (KHTML, like Gecko) ReactNativeDebugger/0.7.13 Chrome/58.0.3029.110 Electron/1.7.9 Safari/537.36
If I am unable to do this with the React Native Debugger, can anyone suggest any steps to testing via Expo.
Using the latest version of Axios (0.17.1), you make an HTTP request with 'Content-Type': 'multipart/form-data' in the header as follows:
const formData = new FormData();
formData.append('action', 'ADD');
formData.append('param', 0);
formData.append('secondParam', 0);
formData.append('file', new Blob(['test payload'], {
type: 'text/csv',
}));
axios({
url: 'http://localhost:5000/api/hello',
method: 'POST',
data: formData,
headers: {
Accept: 'application/json',
'Content-Type': 'multipart/form-data',
},
});
Two things: I am using url, not uri. Also, please insert your own form data and url. Inspecting the request, which has been replied successfully, this is what I get for the request header:
After hours trying to make it work, I realized that a multipart/form-data needs a boundary that is generated dynamically depending on the amount of data that is being sent.
Here is the code that works for me:
const data = new FormData();
data.append('field_name', 'field_pictures');
data.append('files[file]', fs.createReadStream(filepath), filename);
const headers = {
'Content-Type': 'multipart/form-data',
'Authorization': 'here you can set your headers',
...data.getHeaders() // this line is the key
// you need to mix your headers with those generated by the form data
}
return axios.post(url, data, { headers });
You can do simply:
axios.defaults.headers.common['Content-Type'] = 'multipart/form-data; boundary=someArbitraryUniqueString';
It will set your headers for sure. However, I have been struggling with form data in React Native for a day and without success. After some experimental aproaches, I found out that everything works without debugger. I don't know why but with debugger, I have been sending empty body to the server.
What's more I didn't need to set headers as it is your question in this post.
According to #JMA answer,
import axios from 'axios';
export async function somefunction(data) {
const formData = new FormData(); // No imports needed
for(let key in userData) {
formData.append(key.toString(), data[key].toString())
}
return axios.post(`${ROUTE}`, formData, {
'Content-Type': 'multipart/form-data',
});
}
where: data is your payload to what you want to send. somefunction is function that send POST request to ROUTE.
