A fresher to postman, currently working on API project where I need to delivery to the API and Token the client to integrate with them system, good is I successfully configure the Authorization as OAuth Type as Password Credentials and receiving perfect response as 200.
The issue/confusion is Token is getting expire every hour, I need to Get new Access Token every time.
So, the question is, is it anyway I can overcome this issue?
that no need to get new/refresh token.
can provide the one fix token to client.
You can do it like here. You can get the token in the pre-request field of the collection or request.

EDIT
We can adapt it like this:
Take this and paste it in the "pre-request" field of the collection or the request you will use directly. Create an "environment" value named "accessToken". When each request is run, this method will run first and send the token value to the value in the environment.
// Set refresh and access tokens
const loginRequest = {
url: "exampleurl.com/etc/etc", //YOUR URL
method: 'GET',
header: {
'content-type': 'application/json',
'Accept': "*/*"
} //Since you will be using GET, I deleted the body. If you are sending value you can get the body field from the other example in the link.
};
pm.sendRequest(loginRequest, function (err, res) {
pm.environment.set("accessToken", res.json().accessToken); //The token returned in the response and the environment value to which the value will be sent
});

I am using JWT tokens to authenticate users and protect certain routes.
My app is set up with a login function that receives a username and password from the front end, authenticates the user and passes back a token.
I am able to store my token in localStorage like this.
localStorage.setItem("Token", token);
Any ajax call going forward should be able to use
$.ajax({
type: 'GET',
url: '/protected_route,
headers: {
"Accept": "application/json",
"Token" : localStorage.getItem(Token),
success: (data) => {
// do something with the data
}}
This should work as long as the token is still set in localStorage and not expired. My question is, if I want to redirect right after login to a protected path, how would I do that?
window.location = '/my_profile
does not let me set headers.
I am surprised that I could not find anything regarding this issue. Seems like very common use case when using JWT.
Thanks!!
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 am making an app without login i have successfully fetched access token and used it for authentication of another api. But now i want to check expiry of the access token and if the access token is expired how to send refresh token
i found refreshableFetch but i do not know should i use it or not because it not uses refresh token
fetch('URL', {
method: 'GET',
headers: {
etc...
})
.then((response) => response.json())
.then((responseData) => {
this.setState({data: responseData})
})
I am fetching the data as regular. Please suggest me methods to check expiry of access token and to use refresh token
I can suggest you the flow of how you can achieve your desire goal
fetch access token
send access token with every request after that.
check on server end for expiry of each incoming request token.
if token has expired (I assume you have a date in your db) send { status: false , message: "token expired" } else { status: true,
data: "YOUR DATA", message: "" }
check for status on client end, if status is false && message is token expire call refresh token api
In refresh token api, update new token on server
I tried to explain you the flow as I am unaware of your backend logic and code. Hope you can modify the code accordingly as you get the gist :)
I have tried to send axios get request using vue.js and it worked just fine when there was no need to send headers. However, when it was required to send an authorization jwt, i was getting CORS error: "Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource." I don't know why is this problem occurring since there is Access-Control-Allow-Origin: '*' header in the response. My code is the following:
axios.get(url, {
headers: {
'Authorization': 'Bearer TOKEN'
}
})
.then(function (response) {
console.log(response.data)
})
The weirdest thing is when I use querystring.stringify or JSON.stringify on the header, I don't get the error 403(forbidden), but just an error 401 - Unauthorized. I tried with variable and with the token itself and it didn't work.
I tried to send a post request in order to get a web token with required data - username an password and it worked. I was able to get the token.
I made a whole bunch of research the last two days on this and I found different kind of request structure and configs which I tried all of them, but none were efficient. Is there a way to check if the request is being send with the header? Is something else the problem? If someone can help, I would appreciate. Thanks.
I think you should add this code to the bootstrap.js (or where the axios is defined):
window.axios = require('axios'); // I think its already added
window.axios.defaults.headers.common = {
'X-Requested-With': 'XMLHttpRequest'
};
You didn't mention, but I guess you use laravel, or other framework, what is protected from csrf attack, thats why you need to add the generated token to your ajax request header.
Using sydjs as book to get everything working
I'm trying to signup users via POST request via api:
/api/app/signup-email
Whenever I send data with only email&pass - everything works. If I try to add name parameter - it always fails.
Registration on front-end works as it should
Sending data as:
let parameters = [
"email": "\(email)",
"password": "\(password)",
"name": [
"first": "\(firstname)",
"last": "\(lastname)"
]
]
Maybe anyone has any idea why it doesn't work with name included? Thx.
It won't work because login request in Keystone need a _CSRF token validation, you need to provide it as parameter.
One example is first make a GET request to your login page (The CSRF Token will be in the HEADER response), save it and then make your login request passing the CSRF token obtained in the previous request.
This will be helpful KeystoneJS signin
I implemented a login against the REST-API of keystone (v4.0.0-beta.5). On the client-side I chose npm request. I enabled request's cookie-functionality (config option request.defaults({ jar: true });).
The login consisted of two separate-requests:
A simple GET-request against: https://www.yourkeystoneapp.com/keystone/session/signin
npm request will receive a cookie containing the CSRF token. There is nothing else you need to do with it. npm request will use the received cookie for all subsequent http-requests.
A POST-request containing a simple JSON body with your credentials:
{
email: 'user#yourkeystoneapp.com',
password: 'yourpassword'
}
The POST-request will be answered by Keystone with a valid user-object, if the credentials were correct.
All subsequent http-requests will be part of a valid session, as long as the CSRF-token is valid.
Code examples:
// enable cookies
request.defaults({
jar: true
});
// first request to obtain the cookie
request('https://www.yourkeystoneapp.com/signin', {/* some options */});
// second request to POST your credentials
var loginOptions = {
method: 'POST',
url: 'https://www.yourkeystoneapp.come/api/session/signin',
headers: {
'content-type': 'application/json',
'accept': 'application/json'
},
body: JSON.stringify({
email: 'user#yourkeystoneapp.com',
password: 'yourpassword
})
};
// issue POST request.
request(loginOptions);
// You are now logged in
If you are using npm request, as I did, you have to take a couple of measures to sync the requests you issue, as npm request works asynchronously. Making use of npm request's API and its callback-functions is mandatory.
