使用 ngResource（1.0.6 和 1.1.4）更改 POST 请求的 Content-Type 时遇到问题

Question

首先，我知道这个问题已经被问过好几次了。我已经尝试了许多已发布的解决方案，但没有什么对我有用..

以下是其他几个被问到的地方：

• How to specify headers parameter for custom Angular $resource action
• How can I post data as form data instead of a request payload?
• Setting application wide HTTP headers in AngularJS
• https://groups.google.com/forum/#!msg/angular/Mtsf-YdwwWo/P_Ui4t_DiXkJ

尝试：

var app = angular.module('theApp', ['app.services']);


app
  .config(['$httpProvider', function ($httpProvider) {
    // Try (1): This doesn't work
    $httpProvider.defaults.headers.common['Content-Type'] = 'application/json;charset=utf-8';
    // Try (2): This doesn't work either
    $httpProvider.defaults.headers.post['Content-Type'] = 'application/json;charset=utf-8';
  }])


angular.module('app.services', ['ngResource'])
  // Resource for Drupal system/connect.post API (via services.module)
  .factory('SystemConnect', function($resource, $http) {
    // Try (3): There's no way this should work. But what the hell let's try!
    $http.defaults.headers.common['Content-Type'] = 'application/json;charset=utf-8';
    $http.defaults.headers.post['Content-Type'] = 'application/json;charset=utf-8';

    return $resource('api/system/connect.json', {}, {
      post: {
        method: 'POST',
        params: { },
        isArray: true,
        // Try (4): This doesn't work either
        headers: { 'Content-Type': 'application/json;charset=utf-8' }
      }
    });
  });


function SomeCtrl($scope, SystemConnect) {
  // FAIL, this results in "406 Not Acceptable: Unsupported content type application/xml"
  $scope.user = SystemConnect.post();
}
app.controller('SomeCtrl', SomeCtrl);

听起来很多人以前都解决过这个问题。有人可以告诉我正确的方法吗？

PS：奇怪的是，当在 Firefox 中运行此代码时，Angular 使用 'Content-Type: text/plain' 作为 POST！？

我记得读过您必须在帖子中包含内容才能接受您的标题更改。

$scope.user = SystemConnect.post({});
