I'm learning a fullstack app having Vue as front-end, express as back-end and Mongodb.
I have login form and did a simple authentication in the back-end, after user is authenticated i generate JWT and store in user browser, In user's route navigation guards i make a request to sent that token to be verified in the server before let user in protected route
{
path: '/user',
name: 'User',
component: () => import('../views/User.vue'),
beforeEnter: (to, from, next) => {
let token = localStorage.getItem('access_token')
axios.post('http://localhost:5000/authorize', {headers: {
Authorization: `Bearer ${token}`
}})
}
}
But i couldn't sent headers which included token to the server, it got undefined So how to do this properly ?
In order to authenticate, your header must have a key of Content-Type and a Value of application/json
Try using Postman to login. You should receive a JWT ${token} in the response.
Once you are authenticated, all of your requests must include the following Key/Value pairs in the header:
Content-Type: application/vnd.api+json
Accept: application/vnd.api+json
Authorization: Bearer ${token}
Note: You must include the text "Bearer " (with a space) in the Authorization header and it is case-sensitive.

Hi all!
I'm trying to solve a bit of load testing.
Our API has throttling on that particular endpoint, but requests are disctinted by user, the system solve from the provided token.
When I trying the same scenario from different windows/browsers the throttling is working as expected but when the request sent from Postman the response is 429.
Tried the header "Connection":"close", and disabling the "User-Agent" and not allowing the cookie reuse (ARRAffinity is by default because of azure).
Tried already to run two separate request, where the first is the token request with a user then the actual request to the endpoint where the throttling is enabled.
Tried also to send the request then in the Test part as a callback after the token request sending the request to throttled endpoint like that:
pm.test("got token", function() {
let token = pm.response.json().accessToken;
pm.expect(token).to.not.be.null;
const exportRequest = {
method: 'POST',
url: `${pm.environment.get("base_URL")}/api/Export/Gtin/Excel`,
header: {
"accept": "text/plain",
"Authorization": `bearer ${token}`,
"Content-Type": "application/json-patch+json",
"Connection": "close"
},
body:JSON.stringify({
"companyPrefixId": "098102700",
"exportType": "EveryKeys",
"includeProductInfo": true,
"productInfoLanguageCodes": null,
"exportFileMainLanguageCode": "en"
})
};
pm.sendRequest(exportRequest, (err, response) => {
pm.expect(response).to.not.be.null;
if (err) {
console.log(JSON.stringify(err));
}
});
});
I hope someone can help to solve that, thanks in advance!
Best regards
I have a react native app authenticated with Auth0.
I have an API that uses react native.
When a user signs in, i take the accessToken that is given for that user, and I make request to the API with the accessToken set as the authorization header.
I do so like this:
const requestHeader = {
headers: {
Authorization: `Bearer ${accessToken}`,
}
}
axios.post(API_BASE + '/api/example/', requestHeader)
The accessToken is something short like this: aBQdd0kOvb1pNj-9XDj_C6bKWkMg9D_q
When I try to validate the request with the API, I get this error:
UnauthorizedError: jwt malformed
I know i'm getting this error because the access token isn't a JWT.
I'm validating in the API like this:
exports.checkJwt = jwt({
secret: jwksRsa.expressJwtSecret({
cache: true,
rateLimit: true,
jwksRequestsPerMinute: 5,
jwksUri: 'https://dev-0p1doq9r.auth0.com/.well-known/jwks.json'
}),
audience: 'ddasdsfasdfasd',
issuer: 'safsdfasdfasdfafsdf',
algorithms: ['RS256']
});
I know that accessToken needs to be transformed into a JWT on the client, BUT HOW? I have not found any documentation for this; I have also not found what other properties need to be included in the JWT for validation.
I have a Vue frontend, an Auth0 and Fastify backend. CORS is configured as follows:
fastify.register(require('fastify-cors'), {
origin: 'http://localhost:8080',
methods: 'GET,PUT,POST,DELETE,OPTIONS,HEAD',
allowedHeaders: 'Origin, X-Requested-With, Content-Type, Accept',
})
Frontend headers configuration:
this.$auth.getTokenSilently().then(token => {
this.headers = {
Authorization: `Bearer ${token}` // send the access token through the 'Authorization' header
};
The problem is common:
Access to XMLHttpRequest at 'http://127.0.0.1:3000/dir' from origin 'http://localhost:8080' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.
I've read a lot about CORS, know this is a browser side problem (Insomnia sends requests perfectly). Actually, I do not have clear understanding of what else I should allow and how. Basically I need only standart GET, PUT, POST, DELETE requests allowed. Could you please point out the exact configuration problems in my code?
First 401 was caused by OPTIONS request without autentication token. Actually it should be seamlessly processed by a fastify-cors. But due to an incorrect order of initialisation of on-request hooks (first - mine to autenticate, using fastify-auth0-verify, second - implicit hook from fastify-cors), it never invoked. So you need a precise order of hooks explicit and implicit initialization: first - cors, then second - authentication.
The second problem, 401 on the following POST, happened because of incorrect usage of an axios request params on the frontend Vue side. Headers like { Authorization: 'Bearer SomeVeryLongSecretXYZ'}were passed as, for instance, ...post(url, data, this.headers), but there must be {headers : this.headers}.
Final configuration for CORS:
fastify.register(require('fastify-cors'), {
origin: '*',
methods: 'GET,PUT,POST,DELETE,OPTIONS',
})
I have read many articles in stackoverflow and have seen lots of youtube videos, but failed to find the example code which is demonstrating about the flow of saving jwt to localstorage - send back to server with authorization header for verifying.
Here is what I want to do.
When the client logs in to the server, server gives token and saves it to the client localStorage (or sessionStorage).
Whenever the client calls an api which can be accessed only with the token,
client retrieves the token back from the localStorage, and send that token with the authorization header (req.headers.[x-access-token] or req.headers.[authorization]) to the server.
But all of the articles I've been read is explaining this issue with the Postman which does not show how to store it to the localStorage and put it in the authorization header.
Do I have to use localStorage.setItem when the server gives the token to the client, and use and localStorage.getItem and new Headers() with append() or axios before sending that token back to the server?
Examples don't have to be for the express user, but I'd like to get the glimpse of ideas.
You can store your jwt token in localstorage and when ever you make a API call you can add the token to headers as token. if you are using axios you can attach you token to headers like this. Here the token is stored in localstorage with the key 'jwtToken'
axios.post('http://yourendpoint',data,{ headers: { Authorization:localStorage.getItem('jwtToken') } })
.then(response=> console.log(response))
.catch(error => console.log(error));
};
it's easy just Follow me
First of all you have to save the Token(or access token) to the local storage,
in the login component when you are sending request for login do the below:
signin:function() {
axios.post('http://Somthing/log-in/',{
username: this.username,
password: this.password,
})
.then( (response) => {
let token = response.data.access;
localStorage.setItem("SavedToken", 'Bearer ' + token);
axios.defaults.headers.common['Authorization'] = 'Bearer ' + token;
(this.$router.push({name:'HomePage'}));
})
So now the problem is whenever you refresh the Homepage you got 401 error and the solution is : just add this :
{ headers: { Authorization:localStorage.getItem('SavedToken') }}
to the end of each request that need the Token in its header, like below:
axios.get('http://Something/', { headers: { Authorization:localStorage.getItem('SavedToken') }})
.then(response =>{
//something
})
Notice that the token that i used in this explanation was SIMPLEJWT , if you are using somthing else maybe you have to change 'Bearer' to somthing else.
First you have to create or Generate Token through Jwt (jsonWebTokens) then either store it in local Storage or through Cookie or through Session. I generally prefer local storage because it is easier to store token in local storage through SET and retrieve it using GET method. and after retrieving it through get you can verify it through jwt and also authenticate it with bearer authentication..
And for headers add Authorization
fetch("/users", {
method: "Get",
headers: {
"content-type": "application/json",
Authorization: "Bearer" + localStorage.getItem("token")
}
JWTs should never be stored in your localStorage
In fact, they shouldn't even be stored in your cookies, unless you are able to implement very strict CSRF protection
Checkout this for motivation
JWT as an id_token is like your user credentials
JWT as an access_token is like your session token
One option is in-memory. Checkout this for a deep dive
I'm have some issue in my test with superagent and express.js.
it('should 200 with valid login', (done) => {
console.log(createdUser[`${validUser.email}`]['token']);
// JWT eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJfaWQiOiI1ODAwZDllZmNiM2VkMzBhOGZmMDUyOGUiLCJmaXJzdE5hbWUiOiJoYW5zIiwibGFzdE5hbWUiOiJvdHRvIiwiZW1haWwiOiJvdHRvQGV4YW1wbGUuZGUiLCJyb2xlIjoiVXNlciIsImlhdCI6MTQ3NjQ1MDc5OSwiZXhwIjoxNDc2NDYwODc5fQ.OlO_dVMCV6bm7XSyzKLFTgb-efOeyU1TniHEcIY7AHU
request(app)
.get('/api/protected')
.set('Authorization', createdUser[`${validUser.email}`]['token'])
.expect(200)
.end((err, res)=> {
if (err) done(err);
console.log(res.header);
// assert(true, 'asdfasdf');
// done();
});
});
I can't access to the protected path over superagent.
When I'm accessing the path over Postman it is working and I can access the protected path with the suited jwt.
What do have to change in the code?
I want to test different paths.
thanks
Bearer keyword is missing while setting the token
.set('Authorization', `Bearer ${createdUser[`${validUser.email}`]['token']}`)
There is some information missing but here are some possible answers:
You do show how you created your app. If you are using a middleware like express-jwt it needs to be configured before running your test. (app.use(expressJWt...)
Typically, the jwt is sent through the Authorization header using the Bearer schema. ( i.e. Authorization: Bearer eyJhbGciOiJI... )
You can use superagent’s auth function with { type: ‘bearer’ } option:
request.auth(jwt, { type: 'bearer' })
