http获取请求在角度1中不起作用

I am unable to get the URL to work via my service even though I can get it to work in the browser.

我无法通过我的服务获取URL,即使我可以在浏览器中使用它。

The "$http()" doesn't seem to get invoked. The first alert() comes up, but that is it.

“$ http()”似乎没有被调用。第一个警报()出现了,但就是这样。

This is what come back in the browser for the URL = http://localhost:8080/myapp/students

这是在URL = http:// localhost:8080 / myapp / students的浏览器中返回的内容

[{"id":1,"name":"denis","courses":[{"id":1,"name":"mycourse"}]}]

Can someone make some suggestions as to what I am doing wrong?

有人可以就我做错了什么提出一些建议吗?

studentform.js:

    "use strict";
angular.module('StudentApp',[]);
angular.module('StudentApp').service('StudentModel', [function($http){
    this.students = [{name:"NONE"},{name:"NONE2"}];
    this.getStudents = function(){
        alert("getStudents called.");
        $http({method: 'GET', url: 'http://localhost:8080/myapp/students'}).
            then( function(data, status, headers, config){
                alert("Success!!");
                this.students = data;
            }).
            catch( function(data, status, headers, config){
                alert("Failed!!");
                console.log( "Error: " + status );
            });
//      $http.get('http://localhost:8080/myapp/students')
//      .then( function (response) {
//          this.students = response.data;
//      }. bind( this), function (response) {
//          console.log( response.data);
//      }); 
//      $http.get('http://localhost:8080/myapp/students')
//      .then(function(response){
//          alert( "in then");
//          alert( response.date );
//          this.students = response.data;
//      }.bind(this),function(response){
//          alert( "in bind" );
//          console.log(response.data);
//      });
//      alert(response.data);
    }
}]);
angular.module('StudentApp').controller('StudentController', ['StudentModel', function(StudentModel){
    this.model = StudentModel;
}]);

You forgot to add $http as a dependency

你忘了添加$ http作为依赖

Change your service definition to below code:

将您的服务定义更改为以下代码:

angular.module('StudentApp').service('StudentModel', ['$http', function($http){
