If you create the application in localhost header('Access-Control-Allow-Origin: *'); and if it is not working, install the CORS Everywhere plugin in your browser and then check the response and it will work fine.
Plugin URL :
For Firefox : https://addons.mozilla.org/en-US/firefox/addon/cors-everywhere/
For Chrome : https://chrome.google.com/webstore/detail/allow-cors-access-control/lhobafahddgcelffkeicbaginigeejlf?hl=en
Also, Chrome does not support localhost for CORS requests (an error opened since 2010) [1], if you inspect the thread of this error.

I have been trying to use the following code using React fetch to get a response from the OpenWeather API:
fetch('api.openweathermap.org/data/2.5/weather?q=Milwaukee&APPID=1234567890')
.then(response => response.text())
.then(data => {
console.log(data)
When I skip react and just copy the url (api.openweathermap.org/data/2.5/weather?q=Milwaukee&APPID=1234567890) into the browser I get a totally valid response. (For example ) When I use the fetch code in my React application, however, I get the following error:
Request URL: http://localhost:3000/api.openweathermap.org/data/2.5/weather?q=Milwaukee&APPID=1234567890
Request Method: GET
Status Code: 431 Request Header Fields Too Large
Remote Address: 127.0.0.1:3000
Referrer Policy: no-referrer-when-downgrade
I am running my react application off localhost from create-react-app. Why can I access that API just fine from my browser but get an error in my app?
Extra Information
In case it is useful here is the link to sign up for a free OpenWeather API
Here is the rest of the information from the response header:

(My APPID is fake in all these examples, so the request won't work by just copying and pasting what I have)
It's a pretty "catchy" bug - you are missing http:// in front of your url, so:
fetch('https://api.openweathermap.org/data/2.5/weather?q=Milwaukee&APPID=1234567890')
Since you've missed it, url is resolved to this (you can see it in your Network tab):
http://localhost:3000/api.openweathermap.org/data/2.5/weather?q=Milwaukee&APPID=1234567890
I have server running on localhost:8080 (localhost:3000 request is redirected to localhost:8080 by proxy definition in package.json) and sending requests from ReactJS app to this server on localhost. In all browsers suddenlly started occuring this problem. Requests (except keepalive request and 1 or 2 others) return 400 but does not reach server at all. E. g. in Chrome it is happening for all requests but in Firefox a few requests return status code 200 and response with data without problem but other requests behave as mentioned above.
I am using Windows 10.
All browsers have problems: Chrome, Firefox, IE, Edge, Opera, Chromium
I tried turning off defender firewall and AVG.

I am not BE developer but I was told it is not problem on server (on localhost), it is just something in my computer.
What could be causing this problem? Could it be something in Windows or some application intervenes to requests and returns 400 without reaching server? How am I able to find out or solve this problem?
Thanks for any helpfull answer
EDIT:
Not CORS problem because requests returning 400 are not reaching server at all. And also some non-simple requests return 200 without problem in few browsers (e. g. Firefox).
SOLUTION:
Solved by restoring Windows to factory settings.
I'm writing the client-side of an app with ReactJS, I'm stuck at getting data from a certain api. I get "No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:3000' is therefore not allowed access" error.
As I suppose the server is missing the "Access-Control-Allow-Origin" headers in order to enable CORS but what I don't understand is why when I'm trying to make an AJAX call with "Restlet Client - REST API testing" browser extension it actually works. I get a following success response. But It doesn't work inside my actual React Request. Is there a way I can to get rid of this error without any changes on the server side? Why does this extension actually work?

My React code but nothing special in there, just testing if I'm getting a response
componentWillMount() {
const url = "https://myserver.ru/api/issue?perPage=10";
Request.get(url).then((response) => {
this.setState({
issues: response
});
});
}
If you are making a cross-site requests then browser will expect Access-Control-Allow-Origin headers from the server. The value of that header can be,
Access-Control-Allow-Origin: *
or
Access-Control-Allow-Origin: http://localhost:3000
When you are requesting from localhost, make sure it also need to add port number as well.
More about CORS documentation:

Hope it helps.
In my angular controller code my http get method not working with header but the same request working in postman
$http({
method: 'GET',
url: 'http://localhost:8080/api/profiles',
headers: {
'Authorization': 'Bearer 78954642-sf25-4sd6-sdf2-99582369d5af',
'Content-Type':'text/plain'
}
}).then(function(success) {
console.log(success);
}, function(error) {
});
Showing following error
Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://quotebuilder' is therefore not allowed access. The response had HTTP status code 401.

What is wrong here ? please help me to resolve the issue
Your should make CORS disabled in your server side to make this work. A resource makes a cross-origin HTTP request when it requests a resource from a different domain, or port than the one which the first resource itself serves see dtails here. If you are using spring or other server side web frameworks you need to disable that from there.
I'm working with an Angular app that talks to a REST api.
I have set up access-control so that my GET requests are working as expected. (The browser sends a preflight OPTIONS request and then the subsequent GET fires).
However, I am running into problems with my PUTs.
The problem is that with PUTs the options preflight seems to return okay but then the PUT never fires.
First I will show what works and then what is failing. I am using Charles to spy on the calls.
GET (working)
1) preflight request
OPTIONS /v1/account HTTP/1.1
Host api.mysite.com
Access-Control-Request-Method GET
Origin http://127.0.0.1:9000
User-Agent Mozilla/5.0 (Macintosh; Intel Mac OS X 10_9_2) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/34.0.1847.137 Safari/537.36

Accept */*

2) preflight response

3) The GET request
GET /v1/account HTTP/1.1
Host api.mysite.com
Accept application/json, text/plain, */*
Origin http://127.0.0.1:9000

4) The GET response
{ some json as expected }
PUT (not working)
Now, here is the PUT that seems to return an okay preflight response but never gets to the PUT request:
1) preflight request
OPTIONS /v1/account HTTP/1.1
Host api.mysite.com
Access-Control-Request-Method PUT
Origin http://127.0.0.1:9000
User-Agent Mozilla/5.0 (Macintosh; Intel Mac OS X 10_9_2) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/34.0.1847.137 Safari/537.36

Accept */*

Accept-Encoding gzip,deflate,sdch
Accept-Language en-US,en;q=0.8
2) preflight response
HTTP/1.1 200 OK
Server nginx/1.6.0
Date Wed, 21 May 2014 15:51:41 GMT
Content-Type application/octet-stream
Content-Length 0

Access-Control-Allow-Origin *
Access-Control-Allow-Methods *
Access-Control-Allow-Headers Origin, X-Requested-With, Content-Type, Accept, Authorization, WWW-Authenticate, X-BLURR-DEBUG
Access-Control-Allow-Credentials true
The problem
It seems that the preflight response for the PUT is okay, so I'm not sure why the browser never sends the actual PUT request.
Any help or direction would be great! Thank you
The * (star) is not a valid value for the Access-Control-Allow-Methods header. You need to list the actual methods (e.g. GET, PUT). It seems like although the preflight response is successful from the server, the browser is probably still rejecting the preflight and not sending the actual request. Check the browser's console log for any errors.
