为一个请求设置HTTP头

I have one particular request in my app that requires Basic authentication, so I need to set the Authorization header for that request. I read about setting HTTP request headers, but from what I can tell, it will set that header for all requests of that method. I have something like this in my code:

我的应用程序中有一个特定的请求需要基本的身份验证，所以我需要为该请求设置授权头。我读过关于设置HTTP请求头的内容，但是从我所知道的，它将为该方法的所有请求设置头。我的代码中有这样的东西:

$http.defaults.headers.post.Authorization = "Basic QWxhZGRpbjpvcGVuIHNlc2FtZQ==";

But I don't want every one of my post requests sending this header. Is there any way to send the header just for the one request I want? Or do I have to remove it after my request?

但我不希望我的每个帖子都发送这个标题。是否有办法只针对我想要的一个请求发送header ?还是在我提出要求后必须删除它?

There's a headers parameter in the config object you pass to $http for per-call headers:

配置对象中有一个header参数，您将它传递给$http用于每次调用的header:

$http({method: 'GET', url: 'www.google.com/someapi', headers: {
    'Authorization': 'Basic QWxhZGRpbjpvcGVuIHNlc2FtZQ=='}
});

Or with the shortcut method:

或使用快捷方式:

$http.get('www.google.com/someapi', {
    headers: {'Authorization': 'Basic QWxhZGRpbjpvcGVuIHNlc2FtZQ=='}
});

The list of the valid parameters is available in the $http service documentation.

有效参数的列表可以在$http服务文档中找到。

Try this, perhaps it works ;)

试试这个，也许有用。

.factory('authInterceptor', function($location, $q, $window) {


return {
    request: function(config) {
      config.headers = config.headers || {};

      config.headers.Authorization = 'xxxx-xxxx';

      return config;
    }
  };
})

.config(function($httpProvider) {
  $httpProvider.interceptors.push('authInterceptor');
})

And make sure your back end works too, try this. I'm using RESTful CodeIgniter.

确保你的后端也能正常工作，试试这个。我用RESTful CodeIgniter。

class App extends REST_Controller {
    var $authorization = null;

    public function __construct()
    {
        parent::__construct();
        header('Access-Control-Allow-Origin: *');
        header("Access-Control-Allow-Headers: X-API-KEY, Origin, X-Requested-With, Content-Type, Accept, Access-Control-Request-Method, Authorization");
        header("Access-Control-Allow-Methods: GET, POST, OPTIONS, PUT, DELETE");
        if ( "OPTIONS" === $_SERVER['REQUEST_METHOD'] ) {
            die();
        }

        if(!$this->input->get_request_header('Authorization')){
            $this->response(null, 400);    
        }

        $this->authorization = $this->input->get_request_header('Authorization');
    }

}
