Question

我试图用Angular（我的第一个角度应用程序）发出get请求而且它没有工作

这是app.js文件

var app = angular.module('myApp',[]);
app.controller('getCtrl',['$scope',function($scope){
  $http.get("http://127.0.0.1:3000/api/Users")
  .then(function(response){
    $scope.users = response.data;
  });
}]);

和index.html文件

<!DOCTYPE html>
<html>
  <head>
    <meta charset="UTF-8">
  </head>

  <body>
    <div ng-app="myApp">
      <div ng-controller="getCtrl">
          <table>
            <tr ng-repeat = "user in users">
               <td>{{user.name}}</td>
               <td>{{user.lastName}}</td>
            </tr>
          </table>
      </div>
    </div>

    <script src="node_modules/angular/angular.js"></script>
    <script src="app.js"></script>
  </body>
</html>

这是使用rest客户端的get请求的响应

 [
        {
            "_id": "5787c061191313250ba4a7ab",
            "created_at": "2016-07-14T16:40:01.076Z",

            "lastName": "apellido1",
            "name": "user1",
            "__v": 0
        },
        {
            "_id": "5787c069191313250ba4a7ac",
            "created_at": "2016-07-14T16:40:09.952Z",

            "lastName": "apellido2",
            "name": "user2",
            "__v": 0
        },
        {
            "_id": "5787c071191313250ba4a7ad",

            "updated_at": "2016-07-14T16:40:17.518Z",
            "lastName": "apellido3",
            "name": "user3",
            "__v": 0
        },
        {
            "_id": "5787c95b0b2e8aa6183044dc",
            "created_at": "2016-07-14T17:18:19.643Z",
            "updated_at": "2016-07-14T17:18:19.643Z",
            "lastName": "apellido4",
            "name": "nombre4",
            "__v": 0
        },
        {
            "_id": "5787ca740b2e8aa6183044de",
            "created_at": "2016-07-14T17:23:00.229Z",
            "updated_at": "2016-07-14T17:23:00.229Z",
            "lastName": "apellido5",
            "name": "nombre5",
            "__v": 0
        },
        {
            "_id": "5790ec389f3a7a0b0a603be2",
            "created_at": "2016-07-21T15:37:28.671Z",
            "updated_at": "2016-07-21T15:37:28.671Z",
            "lastName": "apellido6",
            "name": "nombre6",
            "__v": 0
        }
    ]

在网页上

结果是空的，就好像请求是空的，我不知道我是否错过了某些东西

Answer 1

var app = angular.module('myApp',[]);
app.controller('getCtrl',['$scope','$http',function($scope,$http){
  $http.get("http://127.0.0.1:3000/api/Users")
  .then(function(response){
    $scope.users = response.data;
  });
}]);

修复

将正确的$http依赖项注入控制器构造函数
response.data

Angular get请求不显示任何内容
