I'm developing f/e page and b/e server.
f/e : react, localhost:3000
b/e : expresses, localhost:80
and I also hosted both server with different domain.
I have send a request using axis to the b/e server to get authorization cookie.
I received set-cookie header but i can't see it on my application tab.
I have searched a lot of posts.
They said that I should add an withCredentials option to axios config.
And also I need to add credentials option to b/e CORS setting.
So I fixed all of them.
But still I cannot get access to the cookies.
By the way, I cannot see or get access to the cookie. But if I send a request to B/E server, the cookies are sent correctly.
I have this issue for months.
Please help me out experts.
And please let me know if need more information.
here is my codes
// expressjs
app.use(cors({
origin: true,
credentials: true,
}));
...
res.cookie('SID', token, {
httpOnly: true, secure: true, sameSite: 'None'
});
res.cookie('SSID', token, {
httpOnly: false, secure: true, sameSite: 'None', path: '/'
});
...
I did it with/without defaults option and also with/without inline option
//react axios
...
axios.defaults.withCredentials = true;
...
const {status, data} = await axios.post(`${url}/api/blah`, {
something
}, {withCredentials: 'include'});
Response cookie
Chrome application cookie
I believe the right syntax for withCredentials on axios is:
//react axios
//...
axios.defaults.withCredentials = true;
//...
const {status, data} = await axios.post(`${url}/api/blah`, {
something
}, {withCredentials: true}); // instead of 'include'
I remember having an issue where axios.defaults.withCredentiasl = true solved it, but you probably don't want to keep it like that forever, so I'd suggest that you set it back to false after the call is finished. Also, the issue looks fixed on axios repo, so I'd try to solve it without changing the defauls.
I have an application based FastAPI Which serves as the backend for a website And currently deployed on a server with an external IP. The frontend is situated at another developer, temporarily in local hosting.
At the beginning of the work we encountered a CORS problem, which was solved by using the following code I found on the Internet:
from fastapi.middleware.cors import CORSMiddleware
...
app.add_middleware(
CORSMiddleware,
allow_origins=['http://localhost:3000'],
allow_credentials=True,
allow_methods=["*"],
allow_headers=["*"],
)
The addition allowed Frontend to make requests properly, but for some reason, cookies that are set to send (and work properly in the Swagger UI) are not set in Frontend.
The client side look like:
axios({
method: 'POST',
baseURL: 'http://urlbase.com:8000',
url: '/login',
params: {
mail: 'zzz#zzz.com',
password: 'xxxxxx'
},
withCredentials: true
}).then( res => console.log(res.data) )
.catch( err => console.log(err))
Setting and reading cookies in FastAPI can be done through the use of the Request class:
Setting the cookie refresh_token
from fastapi import Response
#app.get('/set')
async def setting(response: Response):
response.set_cookie(key='refresh_token', value='helloworld', httponly=True)
return True
Setting httponly=True makes sure the cookie can't be accessed by JS. This is great for sensitive data such as a refresh token. But if your data isn't that sensitive then you can just omit it.
Reading the cookie
from fastapi import Cookie
#app.get('/read')
async def reading(refresh_token: Optional[str] = Cookie(None)):
return refresh_token
You can find more information on using cookies as parameters on the FastAPI docs here.
Remove the wildcards since wildcarding is not allowed with allow_credentials=True :
app.add_middleware(
CORSMiddleware,
allow_origins=['http://localhost:3000'],
allow_credentials=True,
allow_methods=["GET", "POST", "OPTIONS"], # include additional methods as per the application demand
allow_headers=["Content-Type","Set-Cookie"], # include additional headers as per the application demand
)
Set samesite to none while setting the cookie:
# `secure=True` is optional and used for secure https connections
response.set_cookie(key='token_name', value='token_value', httponly=True, secure=True, samesite='none')
If client side is using Safari, disable Prevent cros-site tracking in Preferences. That's It!
For Cross-Origin Situation Cookie Setting, Check things below 👇🏻
Pre-requirements
Your FE, BE servers need to talk each other with https protocol. (Set SSL Certificates using let's encrypt or other services)
Make sure your domain doesn't include port
Backend
Server Setup
Add FE Domain to allow_origins
Set allow_credentials True
allowed_methods should not be a wildcard("*")
allowed_headers should not be a wildcard("*")
Cookie Setup
secure = True
httponly = True
samesite = 'none'
List item
Fastapi Example
# main.py
app.add_middleware(
CORSMiddleware,
allow_origins=settings.ALLOWED_ORIGINS,
allow_credentials=True,
allow_methods=["GET", "POST", "HEAD", "OPTIONS"],
allow_headers=["Access-Control-Allow-Headers", 'Content-Type', 'Authorization', 'Access-Control-Allow-Origin'],
)
# cookie
response = JSONResponse(content={"message": "OK"})
expires = datetime.datetime.utcnow() + datetime.timedelta(days=30)
response.set_cookie(
key="access_token", value=token["access_token"], secure=True, httponly=True, samesite='none', expires=expires.strftime("%a, %d %b %Y %H:%M:%S GMT"), domain='.<YOUR DOMAIN>'
)
Frontend
Include header "Access-Control-Allow-Origin": ""
Set withCredentials: true
Axios Example
// post request that sets cookie
const response = await axios.post(
"https://<Target Backend API>",
{
param1: "123",
param2: "456",
},
{
headers: {
"Access-Control-Allow-Origin": "https://<FE DOMAIN>",
},
withCredentials: true,
},
);
Reverse Proxy Server (If you have)
Allow "OPTIONS" method (this is need when browser check server options in preflight request)
Check if any middlewares blocks your preflight requests. (e.g. Nginx Basic HTTP Authentications can block your request)
IMPORTANT
if your FE use subdomain like dev.exmaple.com and your BE also use subdomain like api.example.com, you should set cookie domain to .example.com so the subdomain services can access root domain cookie!!
In FastAPI you can set cookies via response.set_cookie,
from fastapi import FastAPI, Response
app = FastAPI()
#app.post("/cookie-and-object/")
def create_cookie(response: Response):
response.set_cookie(key="fakesession", value="fake-cookie-session-value")
return {"message": "Come to the dark side, we have cookies"}
It should be noted though that these are NOT SECURE SESSIONS you should use something like itsdangerous to create encrypted sessions.
In response to the requests not seeming to not be sent; You should make sure the option for which urls the cookies are valid for are being set.
By default they are typically / which means everything however your system might be setting them to a specific case with CORS setup.
I'm new at ReactJS but I'm trying to learn by myself now. I'm facing a problem when I try to add data do may Database, in my RestAPI with MongoDB, using fetch function on my web Application. When I click my button, it runs the following code:
SubmitClick(){
//console.log('load Get User page'); //debug only
fetch('http://localhost:4000/users/', {
method: 'POST',
headers: {
'Authorization': 'Basic YWRtaW46c3VwZXJzZWNyZXQ=',
'Content-Type': 'application/json',
},
body: JSON.stringify({
email: 'deadpool#gmail.com',
first_name: 'Wade',
last_name: 'Wilson',
personal_phone: '(11) 91111-2222',
password: 'wolv3Rine'
})
})
//this.props.history.push('/get'); //change page layout and URL
}
and I get the following message on my browser:
OPTIONS http://localhost:4000/users/ 401 (Unauthorized)
Failed to load http://localhost:4000/users/: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:3000' is therefore not allowed access. The response had HTTP status code 401. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.
Uncaught (in promise) TypeError: Failed to fetch
My RestAPI have Basic Auth, but i don't know what i'm supposed to insert in headers to have access. I got this 'Authorization': 'Basic YWRtaW46c3VwZXJzZWNyZXQ=', from Postman, when I configured the Authorization tab, and it was automatically added to the headers.
I'm using Google Chrome as my default browser.
My backend code is the following:
const express = require('express');
const bodyParser = require('body-parser');
const mongoose = require('mongoose');
var basicAuth = require('express-basic-auth')
const app = express();
mongoose.connect('mongodb://localhost/usersregs', { useMongoClient: true });
mongoose.Promise = global.Promise;
app.use(basicAuth({
users: {
'admin': 'supersecret',
'adam': 'password1234',
'eve': 'asdfghjkl'
}
}))
app.use(bodyParser.json());
app.use(function(err, req, res, next){
console.log(err);
//res.status(450).send({err: err.message})
});
app.use(require('./routes/api'));
app.listen(4000, function(){
console.log('Now listening for request at port 4000');
});
It may not be the same problem as the OP, but I was able to get basic auth protected fetches working just by adding a credentials mode...
fetch(
'http://example.com/api/endpoint',
{ credentials: "same-origin" }
)
See here: https://github.github.io/fetch/ under Request > Options
You're trying to access port 4000 (your API, or backend) from port 3000 (Your client). This violates the Same-origin policy, even though you're clearly running both the client and the API from the same machine.
To get around this the easiest way is to just fire up your client from the same port as your API (port 4000) this should allow your host to see that you're trying to access resources from the same domain/port which won't force a preflight request.
If that's not possible you'll have to configure CORS for your API, and this question doesn't give any details about the backend so I can't instruct you on how to do that at the moment.
And of course this approach obviously won't work if you're running two separate servers in production, but that's probably outside of the scope of this question.
I am sending requests from the client to my Express.js server using Axios.
I set a cookie on the client and I want to read that cookie from all Axios requests without adding them manually to request by hand.
This is my clientside request example:
axios.get(`some api url`).then(response => ...
I tried to access headers or cookies by using these properties in my Express.js server:
req.headers
req.cookies
Neither of them contained any cookies. I am using cookie parser middleware:
app.use(cookieParser())
How do I make Axios send cookies in requests automatically?
Edit:
I set cookie on the client like this:
import cookieClient from 'react-cookie'
...
let cookie = cookieClient.load('cookie-name')
if(cookie === undefined){
axios.get('path/to/my/cookie/api').then(response => {
if(response.status == 200){
cookieClient.save('cookie-name', response.data, {path:'/'})
}
})
}
...
While it's also using Axios, it is not relevant to the question. I simply want to embed cookies into all my requests once a cookie is set.
You can use withCredentials property.
XMLHttpRequest from a different domain cannot set cookie values for their own domain unless withCredentials is set to true before making the request.
axios.get(BASE_URL + '/todos', { withCredentials: true });
Also its possible to force credentials to every Axios requests
axios.defaults.withCredentials = true
Or using credentials for some of the Axios requests as the following code
const instance = axios.create({
withCredentials: true,
baseURL: BASE_URL
})
instance.get('/todos')
TL;DR:
{ withCredentials: true } or axios.defaults.withCredentials = true
From the axios documentation
withCredentials: false, // default
withCredentials indicates whether or not cross-site Access-Control requests should be made using credentials
If you pass { withCredentials: true } with your request it should work.
A better way would be setting withCredentials as true in axios.defaults
axios.defaults.withCredentials = true
It's also important to set the necessary headers in the express response. These are those which worked for me:
app.use(function(req, res, next) {
res.header('Access-Control-Allow-Origin', yourExactHostname);
res.header('Access-Control-Allow-Credentials', true);
res.header('Access-Control-Allow-Headers', 'Origin, X-Requested-With, Content-Type, Accept');
next();
});
I am not familiar with Axios, but as far as I know in javascript and ajax there is an option
withCredentials: true
This will automatically send the cookie to the client-side. As an example, this scenario is also generated with passportjs, which sets a cookie on the server
So I had this exact same issue and lost about 6 hours of my life searching, I had the
withCredentials: true
But the browser still didn't save the cookie until for some weird reason I had the idea to shuffle the configuration setting:
Axios.post(GlobalVariables.API_URL + 'api/login', {
email,
password,
honeyPot
}, {
withCredentials: true,
headers: {'Access-Control-Allow-Origin': '*', 'Content-Type': 'application/json'
}});
Seems like you should always send the 'withCredentials' Key first.
You can use withCredentials property to pass cookies in the request.
axios.get(`api_url`, { withCredentials: true })
By setting { withCredentials: true } you may encounter cross origin issue. To solve that
you need to use
expressApp.use(cors({ credentials: true, origin: "http://localhost:8080" }));
Here you can read about withCredentials
What worked for me:
Client Side:
import axios from 'axios';
const url = 'http://127.0.0.1:5000/api/v1';
export default {
login(credentials) {
return axios
.post(`${url}/users/login/`, credentials, {
withCredentials: true,
credentials: 'include',
})
.then((response) => response.data);
},
};
Note: Credentials will be the body of the post request, in this case the user login information (Normally obtained from the login form):
{
"email": "user#email.com",
"password": "userpassword"
}
Server Side:
const express = require('express');
const cors = require('cors');
const app = express();
const port = process.env.PORT || 5000;
app.use(
cors({
origin: [`http://localhost:${port}`, `https://localhost:${port}`],
credentials: 'true',
})
);
Fatih's answer is still valid and great in 2022.
Also axios.defaults.withCredentials = true will do the trick.
It seems passing { withCredentials: true } to individual axios calls is deprecated.
How do I make Axios send cookies in requests automatically?
set axios.defaults.withCredentials = true;
or for some specific request you can use axios.get(url,{withCredentials:true})
this will give CORS error if your 'Access-Control-Allow-Origin' is set to
wildcard(*).
Therefore make sure to specify the url of origin of your request
for ex: if your front-end which makes the request runs on localhost:3000 , then set the response header as
res.setHeader('Access-Control-Allow-Origin', 'http://localhost:3000');
also set
res.setHeader('Access-Control-Allow-Credentials',true);
for people still not able to solve it, this answer helped me.
stackoverflow answer: 34558264
TLDR;
one needs to set {withCredentials: true} in both GET request as well the POST request (getting the cookie) for both axios as well as fetch.
Another solution is to use this library:
https://github.com/3846masa/axios-cookiejar-support
which integrates "Tough Cookie" support in to Axios. Note that this approach still requires the withCredentials flag.
After trying for 2 days long and after trying out from the suggestions here this is what worked for me.
express:
cors: cors({ origin: "http:127.0.0.1:3000", credentials: true, })
Cookie : Make sure your cookie has secure: true, sameSite: "None"
Frontend(React)
axios.defaults.withCredentials = true;
(withCredentials : true did not work for me) to the places where you request the cookie as well as to the place where you send the cookie (GET/POST)
Hope this helps others as well.
You are getting the two thinks mixed.
You have "react-cookie" and "axios"
react-cookie => is for handling the cookie on the client side
axios => is for sending ajax requests to the server
With that info, if you want the cookies from the client side to be communicated in the backend side as well, you will need to connect them together.
Note from "react-cookie" Readme:
Isomorphic cookies!
To be able to access user cookies while doing server-rendering, you
can use plugToRequest or setRawCookie.
link to readme
If this is what you need, great.
If not, please comment so I could elaborate more.
For anyone where none of these solutions are working, make sure that your request origin equals your request target, see this github issue.
I short, if you visit your website on 127.0.0.1:8000, then make sure that the requests you send are targeting your server on 127.0.0.1:8001 and not localhost:8001, although it might be the same target theoretically.
This worked for me:
First, I had to make a new instance of axios with a custom config
Then, I used that axios instance to make a post request
See code below:
const ax = axios.create({
baseURL: 'yourbaseUrl',
withCredentials: true,
});
const loginUser = () => { const body ={username:state.values.email, password:state.values.password};
ax.post('/login',body).then(function(response){
return response}).then().catch(error => console.log(error));}
source:
https://www.npmjs.com/package/axios#creating-an-instance
This won't apply to everyone, but I was using a React frontend with Vite and it was serving the localhost as 127.0.0.1:5173, which is what I put as the CORS allowable domain. As soon as I both to localhost everything worked as expected!
// use this while creating axios instance
const API = axios.create({
baseURL: "http://localhost:4000", // API URL
withCredentials: true,
});
// USE THIS MIDDLEWARE in app.js of backend
first, install cors npm i cors
var cors = require("cors"); // This should be at the end of all middlewares
const corsOptions = {
origin: "http://localhost:3000",
credentials: true, //access-control-allow-credentials:true
optionSuccessStatus: 200,
};
app.use(cors(corsOptions));
In my case, the problem was with the cookie, not with Axios; although I was receiving and sending the cookie from / to the same domain / subdomain / host, I was expecting it to work with different resources in different paths - but my coookie was acting like I had set it to a single Path, even though I omitted that attribute. Explicitly setting Path=/; in the cookie solved the issue.
Set the proxy in package.json(Frontend) and restart the server again (problem solved)
I am using Express.js server. With cookie-parser I have opened this endpoint
app.get("/s", (req,res) => {
res.cookie("bsaSession", req.session.id)
res.send("set cookie ok")
})
When I manually use the browser to http://localhost:5555/s where I have the website running the browser debug console shows that the cookie have been applied.
But when I use fetch API to do the equivalent, it does not set the cookie.
async trySetCookie()
{
await fetch("http://localhost:5555/s",{
method: 'GET',
credentials: 'same-origin'
})
}
Why?
I have found the solution. The core of this problem being that my button to trigger the fetch is on http://localhost:3000/. The server is on http://localhost:5555/ (I am simulating real environment on my own machine)
The problem is that this fetch call
async trySetCookie()
{
await fetch("http://localhost:5555/s",{
method: 'GET',
credentials: 'same-origin'
})
}
Without credentials, the browser cannot send or receive cookies via fetch (https://developer.mozilla.org/en-US/docs/Web/API/Request/credentials)
With credentials as same-origin I can see the cookies coming from the server in the Set-Cookie response header, but nothing is being stored in the browser. One strange thing is that this response always have HttpOnly tagged after the cookie string regardless of my {httpOnly : true/false} settings on the server. In the case of manually using the browser to the page to do GET request, HttpOnly is being respected as usual, and the cookies are set.
So the solution is to set credentials as include to allow cross-origin cookie sending.
async trySetCookie()
{
await fetch("http://localhost:5555/s",{
method: 'GET',
credentials: 'include'
})
}
Also, on the server side you need to allow a particular origin manually with new headers:
app.get("/s", (req,res) => {
res.cookie("bsaSession", req.session.id, {httpOnly:false})
res.header('Access-Control-Allow-Origin', 'http://localhost:3000')
res.header('Access-Control-Allow-Credentials','true'
res.send("set")
})
Not doing this results in
XMLHttpRequest cannot load http://localhost:5555/s. Cannot use wildcard in Access-Control-Allow-Origin when credentials flag is true.
But the cookie will be set regardless of this error. Still nice to include that header to silence the error.
If you are using cors middleware for Express it is even easier. You can just use these options
var corsOptions = {
origin: 'http://localhost:3000',
credentials: true
}
app.use(cors(corsOptions))
And of course credentials: 'include' is still required at the client side.
5argon's solution was great for me otherwise, but I had to set origin in express cors to true. So in backend:
app.use(
cors({
origin: true,
credentials: true,
})
);
And in fetch:
fetch("http://localhost:5555/s", {
method: 'GET',
credentials: 'include'
})
