使用“whenPost - respond”方法时，可以访问Angular $ httpBackend中的“标题”

Question

我正在使用$ httpBackend来模拟后端，我希望在收到请求时能够访问标题：

$httpBackend.whenPOST('/movies').respond(function(method, url, data) {

    // How do I get access to the headers.

    // I want to check the headers and retrieve a token.

    var params = angular.fromJson(data),
        movie = MoviesDataModel.addOne(params),
        movieId = movie.id; // get the id of the new resource to populate the Location field

    return [201, movie, { Location: '/movies/' + movieId }];
});

基本上，我想在发送数据之前检查标题中的值。

关于如何做的任何想法？

httpBackend.whenPOST('/movies',data, function(headers){
  return headers['Authorization'] == 'xxx';
})
.respond(function(method, url, data) {
