signout feature

[glicht]

Hi,

I am doing a simple test via the sample web page: https://github.com/aws/amazon-cognito-auth-js/tree/master/sample

I noticed that I am getting an error on signout. Signout is basically redirecting to a url of the following format:

https://<domain>.auth.us-east-1.amazoncognito.com/logout?logout_uri=<logouturl>&client_id=<client_id>

And then I get an error stating:

Required String parameter 'redirect_uri' is not present

I assume the redirect is used to clear the cookies, but it seems to be failing. I tried playing with this a bit by changing logout_uri to redirect_uri but couldn't get it to redirect back to my logout uri.

redirect is the uri used to go after auth signs-in/out, and it has to be the same uri that you use when you request the auth. It is like a contract to double check it is the right auth logic.

I would suggest to double check your settings vs your client config.

This is a working config:

private initCognitoSDK(){
    let authData = {
      ClientId : this.config.clientId, // Your client id here
      AppWebDomain : this.config.appWebDomain,
      TokenScopesArray : this.config.tokenScopesArray,
      RedirectUriSignIn : this.config.redirectUriSignIn,
      RedirectUriSignOut : this.config.redirectUriSignOut
    };
    return new AWSCognito.CognitoIdentityServiceProvider.CognitoAuth(authData);
  }

And the example config:

{
  "base_url": "https://localhost:3004/",
  "clientId": "your_app_id_configured_at_the_console",
  "appWebDomain": "your_project.auth.us-east-1.amazoncognito.com",
  "tokenScopesArray": ["phone", "email", "profile","openid", "aws.cognito.signin.user.admin"],
  "redirectUriSignIn": "https://localhost:3000/", // <- this has to match the App config in cognito.
  "redirectUriSignOut": "https://localhost:3000/" // <- this has to match the App config in cognito.
}

*I would test this until getting a working example, then modify as needed.

Thanks. I got it working. I configured the logout url wrong in the user pool configuration (basically had a typo in the url).

The error message returned is such a case is really misleading and I think it can be improved.

Anyway, I am closing the issue.

When using /logout?client_id=&redirect_uri= the error message is:

Required String parameter 'response_type' is not present

It should say:

Required String parameter 'logout_uri' is not present

Hi,

When user clicks on logout button, My code is as below to logout from cognito,

var xhttp = new XMLHttpRequest(); if (this.readyState == 4 && this.status == 200) { console.log(this.responseText); } var url = "https://domain-name.auth.us-east-1.amazoncognito.com/logout?logout_uri=https://s3-eu-west-1.amazonaws.com/bucket-name/logout.html&client_id=";

xhttp.open("GET", url, true); xhttp.send();

I am getting CORS issue when GET request is called.

Can anybody help me to fix this?

Thank you in advance!

I tried the same with Postman, I was able to redirect to the logout.html
