Question

我是Angular JS的新手，我正在尝试使用JSON数据调用Rest API。但是当我运行我的HTTP服务器时，什么都没有显示出来。当我在控制台中删除响应时，我收到了响应。

Htmlcode：

<html ng-app="myapp">
<head>
<div ng-controller="header">
    <h1><center>{{apptitle}}</center></h1>
    </div>
<div ng-controller="contactinfo">
    <table class="table">
        <thead>
            <tr>
                <th>Sl.No</th>
                <th>Name</th>
                <th>Address</th>
                <th>Phno</th>
            </tr>
        </thead>
        <tbody ng-repeat="info in contact">
            <tr>
                <th scope="row">1</th>
                <td>{{ info.name }}</td>
                <td>{{ info.location }}</td>
                <td>{{ info.phone }}</td>
            </tr>
            <tr>
                <th scope="row">2</th>
                <td>{{ info.name }}</td>
                <td>{{ info.location }}</td>
                <td>{{ info.phone }}</td>
            </tr>
            </tr>
        </tbody>
    </table>
</div>

角度代码：

var app = angular.module('myapp',[]);
    app.controller('header',function($scope){
        $scope.apptitle = "Basic contacts App"
        }); 
    app.controller('contactinfo',function($scope,$http){
        $http.get('http://localhost:3000/contactinfo')
            .then(function(response){
                console.log(response);
            $scope.contact = response.data.contactinfo;
        });
    });

期待响应数据：

{
"contactinfo" : [
    {
        "name" : "Jeremy Franke",
        "location":"madrid , Unitedkingdom",
        "phone" : 9874563210
    },
    {
        "name" : "Jade Raymond",
        "location":"portland , Netherland",
        "phone" : 9874563210
    },
    {
        "name" : "Franklin",
        "location":"texas , UnitedStates",
        "phone" : 9874563210
    }
]

}

请仔细比较您的解决方案与此 demo fiddle 。你的方法很好，所以应该有另一个问题。也许您可以在将解决方案与此可运行代码进行比较时重现您的问题。

AngularJS应用程序

    var app = angular.module('myapp', []);

    app.controller('header', function($scope) {
      $scope.apptitle = "Basic contacts App"
    });


    app.controller('contactinfo', function($scope, $http) {
      $http.get('./data.json')
        .then(function(response) {
          console.log(response);
          $scope.contact = response.data.contactinfo;
        });
    });
