所以我一直得到这个ReferenceError: $http is not defined，即使我在控制器中包含$http，这似乎是此错误消息的最常见原因。我还尝试将$ http传递给函数本身，但这并没有解决它。
我觉得我错过了一些非常明显的东西，所以任何帮助都会非常感激，谢谢！
为了清楚起见，我已经包含了整个脚本。您可以在finaliseDay函数内查看脚本末尾的发布请求。
谢谢！
这是错误：

提供商无法在带有后缀＆＃39;提供商＆＃39;的控制器内使用，您只能通过提供商名称访问它们，此处仅$http，同时删除; }
配置初始化后
$httpProvider设置应在角配置阶段
<强> CODE
angular.module('goalzy', [])
.config(['$httpProvider', function($httpProvider) {
$httpProvider.defaults.headers.post['Content-Type'] = 'application/json; charset=utf-8';
}]);
.controller('TodoController', ['$scope', '$http', function($scope, $http) {
//controller code here
}]);
注意：请务必从控制器中删除$httpProvider.defaults.headers.post['Content-Type'] = 'application/json; charset=utf-8';行

您不必在控制器中使用“$ httpProvider”，而是使用$ http。
e.g。
$http.defaults.headers.post['Content-Type'] = 'application/x-www-form-urlencoded;charset=utf-8';
作为最佳做法，请勿在控制器中配置提供程序（$ http）。在配置部分中执行此操作。如下
var app = angular.module('goalzy', []);
app.config(function ($httpProvider) {
$httpProvider.defaults.headers.post['Content-Type'] = 'application/x-www-form-urlencoded;charset=utf-8';
});
app.controller('TodoController', ['$scope','$http', function($scope, $http) {
$scope.title="scope title";
//$httpProvider.defaults.headers.post['Content-Type'] = 'application/x-www-form-urlencoded;charset=utf-8';
}]);
