Postman set-cookie not working with the domain - express

I want to controll authentication with cookies. And In my browser working successfully.
But When I tried to test with postman, Postman doesn't add cookie to new request.
step - I login and response header like that:
But the response cookies tab like that:
And manage cookies window like that:
step - I send a request to unprotected router and I get unauthorized error.
This error started today. I don't remember making any changes to the settings.
Why Im getting this type error. How can I solve this?

I also had this problem, the fix is to remove the secure flag in the cookie when sending cookies from localhost as cookies set as secure can only be sent over HTTPS.

I had this issue when testing a local Laravel Sanctum request to /login.
I had the following .env values set
SESSION_DOMAIN=docker-api-service-name
SANCTUM_STATEFUL_DOMAINS=docker-api-service-name
However these needed to be set to localhost to match the domain of the APP_URL. After this, everything was working fine.
SESSION_DOMAIN=localhost
SANCTUM_STATEFUL_DOMAINS=localhost

Someone mentioned that setting the secure flag to false will solve it, and it will. The explanation however was not entirely correct.
Secure will indeed only work over secure connections (HTTPS). However, it will also work over HTTP if it's done in localhost: https://developer.mozilla.org/en-US/docs/Web/HTTP/Cookies#restrict_access_to_cookies

Continue when HTTP authentication fails

I have created an app (backend and frontend) that is mainly used on a Windows intranet. I'm using Kerberos authentication to do SSO so that anyone logged in to Windows domain is automatically authenticated to the server. To do this I set up Kerberos SPN for server and configured browsers etc and is all working fine in the normal scenario. My problem is that I need to continue if the user is not authenticated (ie connects from outside the Windows domain or does not have their browser configured correctly).
In summary there are two scenarios:
if authenticated OK continue with authorization granted for their ID [currently works]
if not authenticated continue with no (public) authorization [does not work]
In the first case the HTTP requests/responses are:
a. frontend: initial HTTP request
b. backend: no auth found so return 401 unauthorized with WWW-Authenticate:Negotiate header
c. frontend: re-sends request with Authorization header -> decoded to get the login ID
In the 2nd case:
a. frontend: initial HTTP request
b. backend: no auth found so return 401 with WWW-Authenticate:Negotiate (and error text in the body)
c. frontend: browser stops (displaying the body of the response as text to the user)
This is the crux of the problem I need to somehow avoid the browser just completely bombing (as at step c above).
Solutions I have tried:
display a message to the user about how to adjust browser settings to allow SSO to work in the body of the 401 response message. This is pretty ugly looking and does not work for connections from outisde the domain
Tried a 301 redirect in stead of 401 unauthorized response, but the browser does not like this.
Tried a redirect using javascript in the 401 response body, but it is not executed.
Have the backend send 401 but with WWW-Authenticate:Negotiate,Basic. But this display an unneeded login/password dialog and still fails if they don't login.
What I really need is an None option, ie: WWW-Authenticate:Negotiate,None then continue with no auth if the subsequent frontend request indicate "None" was used.
Of course, there isn't a "None" option. :(
It seems that this should be a fairly typical scenario but I have been researching this to no avail for 3 days now. Any advice would be greatly appreciated.
If the browser is connecting from outside the intranet then just continue. That is do not send the 401 response at all (no auth). You should be able to tell from the IP address where they connect from.
Another option is to redirect using JS in a page in the 401 body. As mentioned above I think you need to include Content-type: text/html or Content-type: text/javascript.

Expressjs cookie-session settings not working with Passportjs

I'm trying to call my /auth/user endpoint to get the current user that's logged into my website. But because of the new Chrome update I need to somehow set 'sameSite' and 'secure'. Anyone know of how I can get around this? Am I doing something wrong with cookie-session?
The cookie gets sent by express just fine, but it doesn't come with sameSite and secure settings that I specify in the cookie-session settings (see image). I tried with express-session as well, but for some reason the sameSite and secure settings never propogate to cookie used for oauth.
Btw, the authentication works on localhost addresses, but when I deploy from frontend and backend with heroku, I encounter the issue where I need to set sameSite. Would setting up a proxy or something get around the sameSite issue?
I am working on the same issue. SameSite=None needs the cookie to be secure
https://www.chromestatus.com/feature/5633521622188032
Eventhough I have set "secure: true" I am still seeing the cookie not being created on Chrome, but I do see it on Edge
After 3 days trying to figure It out. I finally found a way around this issue, It's not a fix, I'm quite sure PassportJS will come with a solution for that eventually, but for now It allowed me to get the user from the authentication.
Since we are not being able to get the user from the cookie, but the information is in the server session, the way to get this information is to add to the 'server.js' a route to get the user directly from the server session:
app.get('/api/getUser', (req, res) => {
res.json(req.session.user);
});
For some reason, I suppose the lack of cookie somehow, using the req.session inside of a router is returning undefined, but If used inside 'server.js' (or your server index file) It gets the session.
If you need the req.user._id or some other sensitive information for other requests, I would recommend returning a jwtToken with this information to the frontend (in res.json), then save the token directly in localStorage and pass the token in the body of your requests, is not the ideal, but It's the safer way I could think to keep the ids safe.
I hope It can help you!

Is there a way for a SPA to check if there's a proxy and handling it properly?

We have developped a SPA SaaS and went to a soft production launch recently.
Everything was fine until one of our customers told us they had trouble using the app.
Once they open the app, the first request to our backend triggers their proxy credential prompt. Hopefully on the login request.
They have to enter their proxy credentials to let the request go. All subsequent requests are passing properly and they can use the app.
The problem is:
When they stop using the app, close the browser and then come back the day after, the persistent login tries to connect them to our backend, but the proxy credentials prompt is not triggered and the request fails. All subsquent requests fail also.
For it work again, they have to delete all app data in chrome (so the service worker is unregistered, the localstorage and cache are cleared). The next api call will trigger their proxy credentials prompt and they will be able to work again.
So is there any way for the app to know if the proxy is set or not ? Any way of triggering the proxy prompt if not set or whatever ?
I don't exactly know how those proxies work and we have zero access to the proxy settings.
It surely is something with the credentials expiration after some time but that's all we can figure out right now. Maybe we could monitor some params in the request headers ?
We are using VueJS with axios for the requests.
My guess is when user session credentials get expired, your UI is not handling redirection to login page. When the user login for the first time you should store that the user has logged in successfully in browser localstorage. If your server returns 401 error code, you can delete the flag and redirect the user to login page. You can achieve that using meta fields in router.

Postman Resolving "Invalid CORS request" for a POST Request

I've just started using Postman to test an API I am integrating to.
I have the following error that keeps showing up
Invalid CORS request
Note the following:
The API uses Bearer token authentication(OAuth2). I have this
working without a problem.
I do get the bearer token successfully, assign it to an Environment variable and then attempt to use it for the RESTful operations.
The problem is in the subsequent RESTful operation that uses the token.
When I use an old token (through a POST operation), it rightfully
tells me that it is expired and not authorized.
When I then generate a new one and try to run the restful call, it gives me that Invalid CORS request error.
Using cURL, I have no issues. But I am frustrated by Postman.
What I have found so far:
Using postman with Http POST requests - I don't get the part in bold
Just in case anybody else has this same problem, here is how to solve
it. Go to https://www.getpostman.com/docs/capture in your chrome
browser. Click on interceptor extension and then choose add to
chrome. Once it is added there is a new icon top right of both the
browser and postman that looks like a traffic light. In postman click
this and it turns green. Then add a header to every request going to
third light. Every header consists of the header name and a value.
Start typing over the header name and a list of allowed http headers
comes up. Choose "Origin". In the cell for value simply type the
full URL of your server. (Do not forget the 'http://' or 'https://').
What is the expected response to an invalid CORS request? - Best explanation I have seen so far on CORS errors.
The other material speaks about Access-Control-Allow-Method header, preflight requests
... and there is an illustrative Apache Tomcat flowchart of the CORS flow.
Here's the answer you found again:
Just in case anybody else has this same problem, here is how to solve it. Go to https://www.getpostman.com/docs/capture in your chrome browser. Click on interceptor extension and then choose add to chrome. Once it is added there is a new icon top right of both the browser and postman that looks like a traffic light. In postman click this and it turns green.
... With the bit in bold translated:
Then add a header to your request. The header Key should be "Origin" and the header Value should be the full URL of your server (Do not forget the http:// or https://).
Note that Chrome/Postman won't allow you to add a Header with a Key of Origin without the Interceptor plugin.
Also note that at least on my system the Interceptor icon no longer looks like a traffic light.
If your back-end service side code checks for origin of the request (just to avoid CORS attack) you may face this issues when testing your Rest API through postman.
How to Resolve this .?
You need to install a Chrome plugin called Postman Interceptor (https://chrome.google.com/webstore/detail/postman-interceptor/aicmkgpgakddgnaphhhpliifpcfhicfo?hl=en).
After successfully installing this plugin , in you Postman client you can see small icon called Postman Interceptor , you need to toggle it to turn it on.
Now you can add a Request header as below
RequestHeader Key "Origin"
RequestHeader Value "your application base URL"
Check this image
Now you should be able to over come CORS issues you are facing
Cheers !!
Just avoid using browser/chrome postman plugin. Use the desktop application instead!
Seems our server is seeing from a Postman manual HTTP POST that the orgin is invalid b/c its coming from Postman as "chrome-extension://fhbjgbiflinjbdggehcddcbncdddomop"
Not sure why or how to resolve on client/Postman side. Seems our server is correclty rejecting it as is though and issuing a 403.
Value of "Origin" header set in Postman request should be allowed in API backend. For example, using Spring Boot for API should have next:
#Configuration
public class WebConfig implements WebMvcConfigurer {
#Value("${cors.allowedOrigins}")
private String allowedOrigins;
#Override
public void addCorsMappings(CorsRegistry registry) {
registry.addMapping("/**")
.allowedOrigins(allowedOrigins)
.allowedMethods("*")
.allowedHeaders("*");
}
}
where allowedOrigins is set using application.properties property cors.allowedOrigins having comma separated list of allowed origins, eg:
cors.allowedOrings=http://localhost:8080,http://example.com
and set 'Origin' value in Postman to any url from cors.allowedOrigins
I was getting this error when testing my APIs on the postman. Even after meticulously configuring my cors. So I used Insomnia instead of Postman and it works fine. I guess sometimes postman is the problem as it needs some extra effort.
You can try new version of PostMan. To me it works after upgraded postman version from 5.5.5 to 7.36.5

Error: redirect_uri_mismatch while trying to get access_token using oauth

I am trying to get access_token using the instructions here developers.google.com/accounts/docs/OAuth2InstalledApp (which I have followed very diligently) but keep hitting the redirect_uri_mismatch error. What am I doing wrong?
First I create a installed app/other using the console (
Client ID for native application
Client ID ...
Client secret ...
Redirect URIs
urn:ietf:wg:oauth:2.0:oob
local host url
Got the authorization code successfully using the browser using
https://
accounts.google.com/o/oauth2/auth?client_id=818722811109-8ak0a1l3ooqqt3bd97bktr33ghenlptk.apps.googleusercontent.com&redirect_uri=http://:51551/Callback&response_type=code&scope=https://www.googleapis.com/auth/adexchange.seller.readonly&access_type=offline
curl -d "code=...&client_id=...&client_secret=...&grant_type=authorization_code&redirect_uri=urn:ietf:wg:oauth:2.0:oob" -X POST https://
accounts.google.com/o/oauth2/token
gives me error "redirect_uri_mismatch"
I'm at a loss what I am doing wrong. I use the redirect_uri from the console which is for the non-domain one, but can't get past this error.
Any pointers would be appreciated.
Thanks.
http://:51551/Callback is not a valid redirect_uri, so the link you mentioned can not get authorization code. So I doubt that the authorization code you get in this way.
Use this one:
https://accounts.google.com/o/oauth2/auth?client_id=818722811109-8ak0a1l3ooqqt3bd97bktr33ghenlptk.apps.googleusercontent.com&redirect_uri=urn:ietf:wg:oauth:2.0:oob&response_type=code&scope=https://www.googleapis.com/auth/adexchange.seller.readonly&access_type=offline
Sorry the problem is not in code. stackoverflow does not allow localhost in urls, hence I had to delete that domain to get the post to go through. The code works fine after clicking the accept button I do see the code= in the redirect url in localhost.
The problem is in the curl POST.
