Angular $http.post 不发送任何数据

Question

我非常坚持尝试简单地发布 JSON 数据，但由于某种原因它不起作用。

angular.module('pocket.controllers', [])
  .controller('ArticleList', function($scope, $http) {

    $scope.signIn = function() {

      var postObject = new Object();
      postObject.consumer_key = pocketKey;
      postObject.redirect_uri = "http://www.example.com";

      $http.post(apiUrl, postObject).success(function(data){
        alert(data);
      });
    }

  })

当我在 Chrome 检查器中检查请求时，似乎没有实际发布任何数据：

如您所见，X-Error 是“缺少消费者密钥”，这意味着数据未正确发布。

将此行添加到您的代码中；

$http.defaults.headers.post["Content-Type"] = "application/x-www-form-urlencoded";

修改后的代码会是这样的；

angular.module('pocket.controllers', []) .controller('ArticleList', 函数（$范围，$http）{

$scope.signIn = function() {

  var postObject = new Object();
  postObject.consumer_key = pocketKey;
  postObject.redirect_uri = "http://www.example.com";
  $http.defaults.headers.post["Content-Type"] = "application/x-www-form-urlencoded";
  $http.post(apiUrl, postObject).success(function(data){
    alert(data);
  });
}

})
