Unable to set cookies on server side with Sveltekit - cookies

the title speaks for itself: From one moment to another, I am unable to set cookies from the server page of my Sveltekit project.
In the +page.server.js of my page I have an action in which I am setting a cookie with the set function. After that, when reloading the page, I am trying to retrieve the cookie with the get function inside the load function, but the cookie is undefined. I am quite convinced that it is not set at all, but I don't know why.
export const load = async ({ cookies }) => {
const myCookie = cookies.get('myCookie');
}
export const actions = {
default: async ({ cookies }) => {
//stuff
cookies.set('myCookie', true);
throw redirect(303, '/');
}
}
I specify that this is a procedure I have already done in other projects and it has always worked. What could be the problem? Thank you for your help.
UPDATE:
I don't know if it helps, but I want to specify that I am using Pocketbase and that a cookie is set in the hook.server.js of the project, which I can see in the browser and works correctly:
export async function handle({ event, resolve }) {
event.locals.pb = new PocketBase('http://127.0.0.1:8090');
event.locals.pb.authStore.loadFromCookie(event.request.headers.get('cookie') || '');
if (event.locals.pb.authStore.isValid) {
event.locals.user = serializeNonPOJOs(event.locals.pb.authStore.model);
} else {
event.locals.user = undefined;
}
const response = await resolve(event, {
transformPageChunk: ({ html }) => minify(html, minification_options)
})
response.headers.set('set-cookie', event.locals.pb.authStore.exportToCookie({ secure: false }));
return response
}

Next JS How can i set cookies in an api without errors?

Next JS. I am trying to set some cookies in my /api/tokencheck endpoint. Here is a very simplified version of the code:
import { serialize } from 'cookie';
export default (req, res) => {
/* I change this manually to simulate if a cookie is already set */
let cookieexists = 'no';
async function getToken() {
const response = await fetch('https://getthetokenurl');
const data = await response.json();
return data.token;
}
if (cookieexists === 'no') {
getToken().then((token) => {
res.setHeader('Set-Cookie', serialize('token', token, { path: '/' }));
});
return res.status(200).end();
} else {
return res.status(200).end();
}
};
I have tried a ton of variations as to where to put my return.res.status... code, and tried many different ways to return a success code, but depending on where I put the code I variously end up with either of the following errors:
"API resolved without sending a response for /api/checkguestytoken, this may result in stalled requests."
or
"unhandledRejection: Error [ERR_HTTP_HEADERS_SENT]: Cannot set headers after they are sent to the client"
I seem to have some gap in my knowledge about how the API works in Next JS because I cannot figure out how to just run the async function, get a result, set a couple of cookies and then exit with a 200. Could someone please tell me what I'm doing wrong?

How would I update the authorization header from a cookie on a graphQL apollo mutation or query

I have the following _app.js for my NextJS app.
I want to change the authorization header on login via a cookie that will be set, I think I can handle the cookie and login functionaility, but I am stuck on how to get the cookie into the ApolloClient headers autorization. Is there a way to pass in a mutation, the headers with a token from the cookie. Any thoughts here???
I have the cookie working, so I have a logged in token, but I need to change the apolloclient Token to the new one via the cookie, in the _app.js. Not sure how this is done.
import "../styles/globals.css";
import { ApolloClient, ApolloProvider, InMemoryCache } from "#apollo/client";
const client = new ApolloClient({
uri: "https://graphql.fauna.com/graphql",
cache: new InMemoryCache(),
headers: {
authorization: `Bearer ${process.env.NEXT_PUBLIC_FAUNA_SECRET}`,
},
});
console.log(client.link.options.headers);
function MyApp({ Component, pageProps }) {
return (
<ApolloProvider client={client}>
<Component {...pageProps} />
</ApolloProvider>
);
}
export default MyApp;
UPDATE:I've read something about setting this to pass the cookie int he apollo docs, but I don't quite understand it.
const link = createHttpLink({
uri: '/graphql',
credentials: 'same-origin'
});
const client = new ApolloClient({
cache: new InMemoryCache(),
link,
});
UPDATE: So I have made good progress with the above, it allows me to pass via the context in useQuery, like below. Now the only problem is the cookieData loads before the use query or something, because if I pass in a api key it works but the fetched cookie gives me invalid db secret and its the same key.
const { data: cookieData, error: cookieError } = useSWR(
"/api/cookie",
fetcher
);
console.log(cookieData);
// const { loading, error, data } = useQuery(FORMS);
const { loading, error, data } = useQuery(FORMS, {
context: {
headers: {
authorization: "Bearer " + cookieData,
},
},
});
Any ideas on this problem would be great.
If you need to run some GraphQL queries after some other data is loaded, then I recommend putting the latter queries in a separate React component with the secret as a prop and only loading it once the former data is available. Or you can use lazy queries.
separate component
const Form = ({ cookieData }) => {
useQuery(FORMS, {
context: {
headers: {
authorization: "Bearer " + cookieData,
},
},
});
return /* ... whatever ... */
}
const FormWrapper = () => {
const { data: cookieData, error: cookieError } = useSWR(
"/api/cookie",
fetcher
);
return cookieData ? <Form cookieData={ cookieData }/> : ...loading
}
I might be missing some nuances with when/how React will mount and unmount the inner component, so I suppose you should be careful with that.

request.cookies is undefined when using Supertest

I'm passing my authentication token via an HTTP-Only cookie in my NestJS API.
As such, when writing some E2E tests for my Auth endpoints, I'm having an issue with cookies not being where I expect them.
Here's my pared-down test code:
describe('auth/logout', () => {
it('should log out a user', async (done) => {
// ... code to create user account
const loginResponse: Response = await request(app.getHttpServer())
.post('/auth/login')
.send({ username: newUser.email, password });
// get cookie manually from response.headers['set-cookie']
const cookie = getCookieFromHeaders(loginResponse);
// Log out the new user
const logoutResponse: Response = await request(app.getHttpServer())
.get('/auth/logout')
.set('Cookie', [cookie]);
});
});
In my JWT Strategy, I'm using a custom cookie parser. The problem I'm having is that request.cookies is always undefined when it gets to the parser. However, the cookie will be present in request.headers.
I'm following the manual cookie example from this Medium article: https://medium.com/#juha.a.hytonen/testing-authenticated-requests-with-supertest-325ccf47c2bb, and there don't appear to be any other methods available on the request object to set cookies.
If I test the same functionality from Postman, everything works as expected. What am I doing wrong?
I know this is an old thread but...
I also had req.cookies undefined, but for a different reason.
I'm testing my router independently, not the top level app. So I bootstrap the app in beforeEach and add the route to test.
I was getting req.cookies undefined because express 4 requires the cookieParser middleware to be present to parse the cookies from the headers.
E.g.
const express = require('express');
const bodyParser = require('body-parser');
const cookieParser = require('cookie-parser');
const request = require('supertest');
const {router} = require('./index');
describe('router', () => {
let app;
beforeAll(() => {
app = express();
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: true }));
app.use(cookieParser());
app.use('/', router);
});
beforeEach(() => jest.clearAllMocks());
it('GET to /', async () => {
const jwt = 'qwerty-1234567890';
const resp = await request(app)
.get('/')
.set('Cookie', `jwt=${jwt};`)
.set('Content-Type', 'application/json')
.send({});
});
});
Testing this way allows me to unit test a router in isolation of the app. The req.cookies turn up as expected.
Late but I hope I can help you. The problem is in the initialization of the app object. Probably in your main.ts file you have some middlewares configured as they are: cors and queryParse. You must also put them in your tests when you create the app.
const moduleFixture: TestingModule = await Test.createTestingModule({
imports: [AppModule],
}).compile();
const app = moduleFixture.createNestApplication();
// Add cors
app.enableCors({
credentials: true,
origin: ['http://localhost:4200'],
});
// Add cookie parser
app.use(cookieParser());
await app.init();
As per the article you're following, the code at https://medium.com/#juha.a.hytonen/testing-authenticated-requests-with-supertest-325ccf47c2bb :
1) has the 'cookie' value in .set('cookie', cookie) in lowercase and in your code it's in Pascal case ==> Have you tried with lowercase in your code instead ?
2) the cookie value assigned to the 'cookie' header is not an array, whereas in your code you're assigning an array ==> Have you tried with a non array value ?
So to resume, can you try with the following code:
describe('auth/logout', () => {
it('should log out a user', async (done) => {
// ... code to create user account
const loginResponse: Response = await request(app.getHttpServer())
.post('/auth/login')
.send({ username: newUser.email, password });
// get cookie manually from response.headers['set-cookie']
const cookie = getCookieFromHeaders(loginResponse);
// Log out the new user
const logoutResponse: Response = await request(app.getHttpServer())
.get('/auth/logout')
.set('cookie', cookie) // <== here goes the diff
.expect(200, done);
});
});
Let us know if that helps :)

Apify: Preserve headers in RequestQueue

I'm trying to crawl our local Confluence installation with the PuppeteerCrawler. My strategy is to login first, then extracting the session cookies and using them in the header of the start url. The code is as follows:
First, I login 'by foot' to extract the relevant credentials:
const Apify = require("apify");
const browser = await Apify.launchPuppeteer({sloMo: 500});
const page = await browser.newPage();
await page.goto('https://mycompany/confluence/login.action');
await page.focus('input#os_username');
await page.keyboard.type('myusername');
await page.focus('input#os_password');
await page.keyboard.type('mypasswd');
await page.keyboard.press('Enter');
await page.waitForNavigation();
// Get cookies and close the login session
const cookies = await page.cookies();
browser.close();
const cookie_jsession = cookies.filter( cookie => {
return cookie.name === "JSESSIONID"
})[0];
const cookie_crowdtoken = cookies.filter( cookie => {
return cookie.name === "crowd.token_key"
})[0];
Then I'm building up the crawler structure with the prepared request header:
const startURL = {
url: 'https://mycompany/confluence/index.action',
method: 'GET',
headers:
{
Accept: 'text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8',
'Accept-Encoding': 'gzip, deflate, br',
'Accept-Language': 'de-DE,de;q=0.9,en-US;q=0.8,en;q=0.7',
Cookie: `${cookie_jsession.name}=${cookie_jsession.value}; ${cookie_crowdtoken.name}=${cookie_crowdtoken.value}`,
}
}
const requestQueue = await Apify.openRequestQueue();
await requestQueue.addRequest(new Apify.Request(startURL));
const pseudoUrls = [ new Apify.PseudoUrl('https://mycompany/confluence/[.*]')];
const crawler = new Apify.PuppeteerCrawler({
launchPuppeteerOptions: {headless: false, sloMo: 500 },
requestQueue,
handlePageFunction: async ({ request, page }) => {
const title = await page.title();
console.log(`Title of ${request.url}: ${title}`);
console.log(page.content());
await Apify.utils.enqueueLinks({
page,
selector: 'a:not(.like-button)',
pseudoUrls,
requestQueue
});
},
maxRequestsPerCrawl: 3,
maxConcurrency: 10,
});
await crawler.run();
The by-foot-login and cookie extraction seems to be ok (the "curlified" request works perfectly), but Confluence doesn't accept the login via puppeteer / headless chromium. It seems like the headers are getting lost somehow..
What am I doing wrong?
Without first going into the details of why the headers don't work, I would suggest defining a custom gotoFunction in the PuppeteerCrawler options, such as:
{
// ...
gotoFunction: async ({ request, page }) => {
await page.setCookie(...cookies); // From page.cookies() earlier.
return page.goto(request.url, { timeout: 60000 })
}
}
This way, you don't need to do the parsing and the cookies will automatically be injected into the browser before each page load.
As a note, modifying default request headers when using a headless browser is not a good practice, because it may lead to blocking on some sites that match received headers against a list of known browser fingerprints.
Update:
The below section is no longer relevant, because you can now use the Request class to override headers as expected.
The headers problem is a complex one involving request interception in Puppeteer. Here's the related GitHub issue in Apify SDK. Unfortunately, the method of overriding headers via a Request object currently does not work in PuppeteerCrawler, so that's why you were unsuccessful.

react native get cookies

I had logined in my server with fetch(),I want to know how I get the cookies.
I know that I can use "document.cookie" to get the cookies in a web browser development,but in react native develop how?
thank you very much.
I just came across the same problem.
My first approach was to manually get the cookies from the response headers.
This become more difficult since Headers.prototype.getAll was removed (see this issue).
The details are shown further down below.
Getting and parsing cookies might be unnecessary
First, I want to mention that all the below cookie parsing turned out to be unnecessary because the implementation of fetch on React Native sends the cookies automatically (if the credentials key is set correctly).
So the session is kept (just like in the browser) and further fetches will work just fine.
Unfortunately, the React Native documentation on Networking does not explicitly tell you that it'll work out of the box. It only says: "React Native provides the Fetch API for your networking needs."
First approach
Thus, I wrote a helper function:
// 'headers' is iterable
const get_set_cookies = function(headers) {
const set_cookies = []
for (const [name, value] of headers) {
if (name === "set-cookie") {
set_cookies.push(value)
}
}
return set_cookies
}
fetch(url, {
method: "POST",
credentials: "same-origin", // or 'include' depending on CORS
// ...
})
.then(response => {
const set_cookies = get_set_cookies(response.headers)
})
To parse the cookie strings into objects I used set-cookie-parser.
This way I wanted send the cookies back manually like
import SetCookieParser from "set-cookie-parser"
const cookies_to_send = set_cookies
.map(cookie => {
const parsed_cookie = SetCookieParser.parse(cookie)
return `${cookie.name}=${cookie.value}`
})
.join('; ')
fetch(url, {
method: "POST",
credentials: "same-origin", // or 'include' depending on CORS
headers: {
Cookie: cookies_to_send,
// ...
},
// ...
})
Inspired by jneuendorf, I created a helper method that returns a key/value pair to easily look up the value of a cookie
export const getCookies = function(response) {
const cookies = {}
for (const [name, values] of response.headers) {
if (name === 'set-cookie') {
for (const cookie of values.split(';')) {
const [key, value] = cookie.split('=')
cookies[key] = value
}
}
}
return cookies
}
