Javascript $http.post不发送任何数据

我一直在尝试简单地发布JSON数据，但由于某些原因，它无法工作

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 inspector中检查请求时，似乎没有实际发布任何数据：

如您所见，X错误为“缺少消费者密钥”，这意味着数据未正确发布。

将这一行添加到代码中

$http.defaults.headers.post[“内容类型”]= “application/x-www-form-urlencoded”

修改后的代码将是这样的

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

})

可能的重复也不起作用，我认为这与他们的服务器不支持CORS有关，因此无法执行跨源POST请求。您是在单个域中执行此操作，还是有跨域POST请求？不，这是对Pocket API的跨域请求：

$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);
  });
}
