Vite + React: http://localhost:5173
Express: http://localhost:3000
Here is the code in the express server's login route:
const mycookie = cookie.serialize("jwt", refreshToken, {
httpOnly: true, // Set the HTTP-only flag
secure: true, // Set the secure flag
sameSite: "none",
path: "/", // Set the path of the cookie to '/'
maxAge: 3600, // Set the maximum age of the cookie to 1 hour
});
// Set the cookie in the response headers
res.setHeader("Set-Cookie", mycookie);
res.json({
accessToken,
refreshToken,
});
Here is my cors config:
const allowedOrigins = require("./allowedOrigins");
const corsOptions = {
crendials: true,
origin: function (origin, callback) {
console.log(allowedOrigins.indexOf(origin));
if (allowedOrigins.indexOf(origin) !== -1) {
callback(null, true);
} else {
callback(new Error("Not allowed by CORS"));
}
},
};
Here is my handleSubmit function in the frontend (gets called when the user clicks submit):
const handleSubmit = () => {
console.log("Login");
// axios.defaults.withCredentials = true;
axios.post("http://localhost:3000/api/v1/auth/login", { email, password });
};
Whenever the request is made to the server. The response header does contain the set-Header to set the jwt token but I am not able to see it in my applications tab under cookies in devtools. A pre-flight request also comes in which probably clears the cookie.
My networks tab:
The xhr request:
The OPTIONS request:
The Applications tab:
However, when I disable CORS in the browser, the cookie is getting set.
Networks tab (NOTICE: No PreFlight request)
Applications tab:
I tried working out different answers from stackoverflow answers like this, this, this, and many more along with a reddit post on a similar issue but nothing has worked.
P.S. : I already tried using credentials: true
Background:
I use express-session to do authetication in my MERN project.
After I logged in, a session will be created and sessionId will be send to client side by cookie. So when I am trying to fetch data, server will verify my sessionId.
I run my project in dev-env, and everything goes well. I can get the cookies in chrome devtools.
BUT after I deployed my project on Vercel(Server and Client depolyed separately). When I login in my web, there are no cookies in devtools.Verification failed, no sessionId returned.
Below are my codes:
server side:
//setup express-session
app.use(
session({
secret: process.env.SESSION_SECRET,
store: store,
resave: false,
saveUninitialized: false,
cookie: {
path: "/",
httpOnly: true,
secure: process.env.NODE_ENV === "PRODUCTION" ? true : false,
maxAge: 1000 * 60 * 60 * 24 * 7, // 1 week
},
name: "rd_sid",
})
);
//setup cors
const corsOptions = {
origin: process.env.CORS_ORIGIN.split(",").map(
(origin) => new RegExp(origin)
),
allowedHeaders: "Origin, X-Requested-With, Content-Type, Accept",
credentials: true,
};
app.use(cors(corsOptions));
client side:
export default function ajax(url, data = {}, method = "GET") {
return new Promise((resolve, isRejected) => {
let promise;
// 1.1 Execute ajax request
if (method === "GET") {
promise = axios.get(url, {
params: data,
withCredentials: true,
});
} else if (method === "POST") {
promise = axios.post(url, data, { withCredentials: true });
}
promise
.then((response) => {
// 1.2 If success, call resolve(value)
resolve(response.data);
})
.catch((error) => {
// 1.3 If fail, do not call reject(reason) but alert error message.
message.error("request error:" + error.message);
});
});
}
I set withCredentials to ture, and also set the header for cors. So it will solve the cross domain problem.
I try to switch secure , httpOnly, and change the cookie's name. But they seem not work.
I'm having issues setting a cookie in a react app, In development, it works but when I switch to production the cookie is not received by the browser. I'm using a node.js/express server.
The backend and frontend are both hosted on vercel.
This is the list of things I've tried:
I've set the domain name to be the domain of the frontend(i.e ".vercel.app"),
In the request to the backend using axios, "withCredentials" is set to true
Secure is set to true
cors is enabled
Here's the code for clarification:
The code sending the cookie:
function sendCookie(req, res, token) {
const cookies = new Cookies(req, res, {
keys,
});
return cookies.set("jwt", token, {
domain:".vercel.app"
secure: true,
sameSite:"strict"
path: "/",
httpOnly: false,
});
}
Cors configuration:
app.use(
cors({
credentials: true,
origin: [
"http://localhost:5173",
"https://abc.vercel.app",
],
methods: ["GET", "POST", "DELETE", "PATCH"],
})
);
"https://abc.vercel.app" in this case is the frontend URL
I'd really appreciate any help I can get. Thanks
In my local environment, I'm trying to set up user tokens after login in my NextJS app (localhost:3005), using the response from my express backend (localhost:3020). I can see set-cookie in the response on the server, but the cookies in the getServerSideProps is empty always.
My code is pretty basic:
Express backend
// Cors set up
cors({
methods: "GET,HEAD,OPTIONS,POST",
preflightContinue: false,
credentials: true,
origin: [
"http://localhost:3005",
...
],
optionsSuccessStatus: 204,
})
// Response - can see this cookie in set-cookie
return res.cookie("test", "test1", {
httpOnly: true,
sameSite: "none",
expires,
domain: "localhost:3005", // tried without this also
}).redirect("http://localhost:3005/login");
My NextJS app has the following:
//Login component : on login submit
const resp = await fetch(
`${BACKEND_URL}login?originalUrl=/login`, // Redirecting back
{
headers: new Headers({
Authorization: "Bearer " + someToken,
}),
credentials: "include",
method: "POST",
redirect: "follow", // Tried this but did not work
}
);
// resp.redirected is true
// Login component - triggers correctly but no cookies
export const getServerSideProps: GetServerSideProps = async (ctx) => {
const { req } = ctx;
const { cookies } = req;
console.log("cookies", cookies ); // Always {}
return { props: {} };
};
I have been stuck with this for a while now guys, it seems like I'm missing something very trivial here. I'm not super familiar with NextJs, so any help here would be greatly appreciated. Thanks!
This was happening because of the Chrome SameSite=None + Secure requirement. Setting secure to true in the cookie resolved this issue. I did not have to set up SSL certificates for my local environment, just setting secure worked.
I have problem with setting a cookies via express. I'm using Este.js dev stack and I try to set a cookie in API auth /login route. Here is the code that I use in /api/v1/auth/login route
res.cookie('token', jwt.token, {expires: new Date(Date.now() + 9999999)});
res.status(200).send({user, token: jwt.token});
In src/server/main.js I have registered cookie-parser as first middleware
app.use(cookieParser());
The response header for /api/v1/auth/login route contains
Set-Cookie:token=eyJ0eXAiOiJKV1QiLCJhbGciOiJSUzI1NiJ9.eyJ..
but the cookie isn't saved in browser (document.cookie is empty, also Resources - Cookies tab in develepoers tools is empty) :(
EDIT:
I'm found that when I call this in /api/v1/auth/login (without call res.send or res.json)
res.cookie('token', jwt.token, {expires: new Date(Date.now() + 9999999), httpOnly: false});
next();
then the cookie is set AND response header has set X-Powered-By:Este.js ... this sets esteMiddleware in expres frontend rendering part.
When I use res.send
res.cookie('token', jwt.token, {expires: new Date(Date.now() + 9999999), httpOnly: false}).send({user, token: jwt.token});`
next();
then I get error Can't set headers after they are sent. because send method is used, so frontend render throw this error.
But I have to send a data from API, so how I can deal with this?
I had the same issue. The server response comes with cookie set:
Set-Cookie:my_cookie=HelloWorld; Path=/; Expires=Wed, 15 Mar 2017 15:59:59 GMT
But the cookie was not saved by a browser.
This is how I solved it.
I use fetch in a client-side code. If you do not specify credentials: 'include' in fetch options, cookies are neither sent to server nor saved by a browser, although the server response sets cookies.
Example:
var headers = new Headers();
headers.append('Content-Type', 'application/json');
headers.append('Accept', 'application/json');
return fetch('/your/server_endpoint', {
method: 'POST',
mode: 'same-origin',
redirect: 'follow',
credentials: 'include', // Don't forget to specify this if you need cookies
headers: headers,
body: JSON.stringify({
first_name: 'John',
last_name: 'Doe'
})
})
Struggling with this for a 3h, and finally realized, with axios, I should set withCredentials to true, even though I am only receiving cookies.
axios.defaults.withCredentials = true;
I work with express 4 and node 7.4 and Angular, I had the same problem this helped me:
a) server side: in file app.js I give headers to all responses like:
app.use(function(req, res, next) {
res.header('Access-Control-Allow-Origin', req.headers.origin);
res.header("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept");
next();
});
This must have before all routers.
I saw a lot of added this header:
res.header("Access-Control-Allow-Headers","*");
res.header('Access-Control-Allow-Credentials', true);
res.header('Access-Control-Allow-Methods', 'GET,PUT,POST,DELETE');
but I don't need that.
b) when you define cookie you need to add httpOnly: false, like:
res.cookie( key, value,{ maxAge: 1000 * 60 * 10, httpOnly: false });
c) client side: in send ajax you need to add: withCredentials: true, like:
$http({
method: 'POST',
url: 'url',
withCredentials: true,
data : {}
}).then(function(response){
// do something
}, function (response) {
// do something else
});
There's a few issues:
a cookie that isn't explicitly set with httpOnly : false will not be accessible through document.cookie in the browser. It will still be sent with HTTP requests, and if you check your browsers' dev tools you will most likely find the cookie there (in Chrome they can be found in the Resources tab of the dev tools);
the next() that you're calling should only be used if you want to defer sending back a response to some other part of your application, which—judging by your code—is not what you want.
So, it seems to me that this should solve your problems:
res.cookie('token', jwt.token, {
expires : new Date(Date.now() + 9999999),
httpOnly : false
});
res.status(200).send({ user, token: jwt.token });
As a side note: there's a reason for httpOnly defaulting to true (to prevent malicious XSS scripts from accessing session cookies and the like). If you don't have a very good reason to be able to access the cookie through client-side JS, don't set it to false.
I had the same issue with cross origin requests, here is how I fixed it. You need to specifically tell browser to allow credentials. With axios, you can specify it to allow credentials on every request like
axios.defaults.withCredentials = true
however this will be blocked by CORS policy and you need to specify credentials is true on your api like
const corsOptions = {
credentials: true,
///..other options
};
app.use(cors(corsOptions));
Update: this only work on localhost
For detail answer on issues in production environment, see my answer here
I was also going through the same issue.
Did code changes at two place :
At client side :
const apiData = await fetch("http://localhost:5000/user/login",
{
method: "POST",
body: JSON.stringify(this.state),
credentials: "include", // added this part
headers: {
"Content-Type": "application/json",
},
})
And at back end:
const corsOptions = {
origin: true, //included origin as true
credentials: true, //included credentials as true
};
app.use(cors(corsOptions));
Double check the size of your cookie.
For me, the way I was generating an auth token to store in my cookie, was causing the size of the cookie to increase with subsequent login attempts, eventually causing the browser to not set the cookie because it's too big.
Browser cookie size cheat sheet
There is no problem to set "httpOnly" to true in a cookie.
I am using "request-promise" for requests and the client is a "React" app, but the technology doesn't matter. The request is:
var options = {
uri: 'http://localhost:4000/some-route',
method: 'POST',
withCredentials: true
}
request(options)
.then(function (response) {
console.log(response)
})
.catch(function (err) {
console.log(err)
});
The response on the node.js (express) server is:
var token=JSON.stringify({
"token":"some token content"
});
res.header('Access-Control-Allow-Origin', "http://127.0.0.1:3000");
res.header("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept");
res.header( 'Access-Control-Allow-Credentials',true);
var date = new Date();
var tokenExpire = date.setTime(date.getTime() + (360 * 1000));
res.status(201)
.cookie('token', token, { maxAge: tokenExpire, httpOnly: true })
.send();
The client make a request, the server set the cookie , the browser (client) receive it (you can see it in "Application tab on the dev tools") and then I again launch a request to the server and the cookie is located in the request: "req.headers.cookie" so accessible by the server for verifying.
I had same problem in Angular application. The cookies was not set in browser although I used
res.cookie("auth", token, {
httpOnly: true,
sameSite: true,
signed: true,
maxAge: 24 * 60 * 60 * 1000,
});
To solve this issue, I added app.use(cors({ origin:true, credentials:true })); in app.js file of server side
And in my order service of Angular client side, I added {withCredentials: true} as a second parameter when http methods are called like following the code
getMyOrders() {
return this.http
.get<IOrderResponse[]>(this.SERVER_URL + '/orders/user/my-orders', {withCredentials: true})
.toPromise();}
vue axios + node express 2023
server.ts (backend)
const corsOptions = {
origin:'your_domain',
credentials: true,
optionSuccessStatus: 200,
}
auth.ts (backend)
res.cookie('token', JSON.stringify(jwtToken), {
secure: true,
httpOnly: true,
expires: dayjs().add(30, "days").toDate(),
sameSite: 'none'
})
authService.ts (frontend)
export class AuthService {
INSTANCE = axios.create({
withCredentials: true,
baseURL: 'your_base_url'
})
public Login = async (value: any): Promise<void> => {
try {
await this.INSTANCE.post('login', { data: value })
console.log('success')
} catch (error) {
console.log(error)
}
}
it works for me, the cookie is set, it is visible from fn+F12 / Application / Cookies and it is inaccessible with javascript and the document.cookie function. Screenshot Cookies Browser
One of the main features is to set header correctly.
For nginx:
add-header Access-Control-Allow-Origin' 'domain.com';
add_header 'Access-Control-Allow-Credentials' 'true';
Add this to your web server.
Then form cookie like this:
"cookie": {
"secure": true,
"path": "/",
"httpOnly": true,
"hostOnly": true,
"sameSite": false,
"domain" : "domain.com"
}
The best approach to get cookie from express is to use cookie-parser.
A cookie can't be set if the client and server are on different domains. Different sub-domains is doable but not different domains and not different ports.
If using Angular as your frontend you can simply send all requests to the same domain as your Angular app (so the app is sending all API requests to itself) and stick an /api/ in every HTTP API request URL - usually configured in your environment.ts file:
export const environment = {
production: false,
httpPhp: 'http://localhost:4200/api'
}
Then all HTTP requests will use environment.httpPhp + '/rest/of/path'
Then you can proxy those requests by creating proxy.conf.json as follows:
{
"/api/*": {
"target": "http://localhost:5200",
"secure": false,
"changeOrigin": true,
"pathRewrite": {
"^/api": ""
}
}
}
Then add this to ng serve:
ng serve -o --proxy-config proxy.conf.json
Then restart your app and it should all work, assuming that your server is actually using Set-Cookie in the HTTP response headers. (Note, on a diff domain you won't even see the Set-Cookie response header, even if the server is configured correctly).
Most of these answers provided are corrections, but either of the configuration you made, cookies won't easily be set from different domain. In this answer am assuming that you are still in local development.
To set a cookie, you can easily use any of the above configurations or
res.setHeader('Set-Cookie', ['foo=bar', 'bar=baz']); // setting multiple cookies or
res.cookie('token', { maxAge: 5666666, httpOnly: true })
Both of the will set your cookie while to accessing your cookie from incoming request req.headers.
In my case, my cookie were not setting because my server was running on http://localhost:7000/ while the frontend was running on http://127.0.0.1:3000/ so the simple fix was made by making the frontend run on http://localhost:3000 instead.
I struggle with it a lot so follow below solution to get through this
1 check if you are getting token with response with postmen in my case i was getting token in postmen but it wasn't being saved in cookies.
I was using a custom publicRequest which looks like below
try {
const response = await publicRequest.post("/auth/login", user, {withCredentials: true});
dispatch(loginSuccess(response.data));
} catch (error) {
dispatch(loginFail());
dispatch(reset());
}
I was using this method in other file to handle login
I added {withCredentials: true} in both methods as option and it worked for me.
I am late to the party but nothing fixed it for me. This is what I was missing (and yeah, it's stupid):
I had to add res.send() after res.cookie() - so apperently sending a cookie is not enough to send a response to the browser.
res.cookie("testcookie", "text", cookieOptions);
res.send();
You have to combine:
including credentials on the request with, for example withCredentials: true when using axios.
including credentials on the api with, for example credentials: true when using cors() mw.
including the origin of your request on the api, for example origin: http://localhost:3000 when using cors() mw.
app.post('/api/user/login',(req,res)=>{
User.findOne({'email':req.body.email},(err,user)=>{
if(!user) res.json({message: 'Auth failed, user not found'})
user.comparePassword(req.body.password,(err,isMatch)=>{
if(err) throw err;
if(!isMatch) return res.status(400).json({
message:'Wrong password'
});
user.generateToken((err,user)=>{
if(err) return res.status(400).send(err);
res.cookie('auth',user.token).send('ok')
})
})
})
});
response
res.cookie('auth',user.token).send('ok')
server gives response ok but the cookie is not stored in the browser
Solution :
Add Postman Interceptor Extension to chrome which allows postman to store cookie in browser and get back useing requests.
