The AngularJS $http.post method mimicking a successful $.ajax request is causing a 401 UNAUTHORISED error

I have been working on rewriting a functional $.ajax server call to utilize AngularJS $http.put. However, the $http method returns a 401 unauthorized error.

The original ajax call I am attempting to rewrite is structured like this:

$.ajax({
url: domain + "/api/v1/user/logout/",
timeout: 10000,
type: "POST",
contentType: "application/json",
beforeSend: function(xhr) {xhr.setRequestHeader("Authorization", api_user())},
success: function(data) {
if (data.success) {
notify("Thanks for signing out");
}
}
});

My AngularJS equivalent code looks like this:

logoutUser: function() {
   var config = {headers:  {
        'Authorization': api_user()
      }
   };
   return $http.post(apiDomain + '/api/v1/user/logout/', config).then(function(response)    {
       return response;
   });
}

When I execute this code, the server responds with a 401 unauthorized error and the 'then' part of the $http.post function is not triggered.

EDIT: More details

Upon inspecting through Firebug, the request headers are as follows:

POST /api/v1/user/logout/ HTTP/1.1

Host: localhost:8000

User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.10; rv:40.0) Gecko/20100101 Firefox/40.0

Accept: application/json, text/plain, */*

Accept-Language: en-US,en;q=0.5

Accept-Encoding: gzip, deflate

Content-Type: application/json;charset=utf-8

Referer: http://localhost:8100/

Content-Length: 40

Origin: http://localhost:8100

X-Forwarded-For: 12.13.14.15

Connection: keep-alive

Pragma: no-cache

Cache-Control: no-cache

The POST data retrieved from Firebug reads:

{"headers":{"Authorization":"ApiKey bill:bfab6e5a1fb6e4e405756dcf14a634e86ba05c7b"}}

This leads me to question whether the authorization is being sent as data rather than a header.

Answer №1

It is essential to incorporate an error function in your code to handle a 401 response.

Refer to the following sample code snippet for implementing an error callback function:

// Illustration of a basic GET request:
$http({
  method: 'GET',
  url: '/someUrl'
}).then(function successCallback(response) {
    // This callback will be executed asynchronously
    // Once the response is received
  }, function errorCallback(response) {
    // Executed asynchronously in case of an error
    // Or if the server returns a response with an error status.
});

Answer №2

In certain cases, not all APIs or server endpoints allow calls directly from the front-end. An example of this is the Steam Community Market API (), where Angular front-end calls are not authorized. In such situations, I had to make HTTP calls from the back-end and then pass the data to the front-end for display.

Answer №3

The data you wish to send is specified as the second parameter, with configuration details provided as the third.

$http.post(apiAddress + '/api/v1/user/logout/', {}, config)
