Hi!

We use bearer / token authentication for a mobile app that communicates with our web api. As of now requests that do not contain a proper bearer token will get a response with http status code 302 and the location header with a value like https://example.com/Account/Login?ReturnUrl=/api/foo/bar. How can we change this behaviour and insted return a 401 “Unauthorized” response for requests that do not contain a proper bearer token?

    Sure, what parts would you like to see? Is there a private messaging feature on these boards?

    Hi,

    I'm sorry I haven't been able to get back to you with source. In the meantime I'd just like to clarify what I mean.

    If I make a request to one of the built-in abp endpoints, e.g. get /api/lepton-theme-management/settings without a valid bearer token I get a 401 Unauthorized response with the body <br>

    {
      "error": {
        "code": "Volo.Authorization:010001",
        "message": "Authorization failed! Given policy has not granted.",
        "details": null,
        "data": {},
        "validationErrors": null
      }
    }
    

    <br> However if I make a request to one of our custom controllers in the same way without a valid bearer token I get a 302 Found response with the Location header value https://localhost:44327/Account/Login?ReturnUrl=%2Fapi%2Ffoo%2Fbar instead.

    What do I need to do to get a 401 Unauthorized response from our endpoints like the built-in abp endpoints?

    hi

    This is related to: https://github.com/abpframework/abp/issues/2643#issuecomment-574940166

    You can consider add [Authorize(AuthenticationSchemes = JwtBearerDefaults.AuthenticationScheme)] on your controller or method.

    Thank you! I've added the attribute [Authorize(AuthenticationSchemes = JwtBearerDefaults.AuthenticationScheme)] and now the response is 401 Unauthorized. May I ask if this attribute could have any other unwanted consequences?

    I don't think so.
