选择字段中的空白选项

Question

我想通过数据库中的数据填充我的选项字段。 我收到错误控制台：

Error: [$compile:ctreq] Controller 'select', required by directive 'ngOptions', can't be found! 

我知道Json的正确发送我的数据，因为我看到输出，当我做了水木清华这样的：myaddress.com/forms/usersDB.php?action=get_Logins_info

输出：

[{"id":"1","name":"John"},{"id":"2","name":"Julia"}]

角功能：

$scope.ChooseLogins = []; 
$scope.getLogins = function() { 
    $http.get('forms/usersDB.php?action=get_Logins_info').then(function (data, status, headers, config) { 
     $scope.chooseLogins = data; 
     console.log('Retrieved data from server'); 
     console.log(data); 
    }).then(function (data, status, headers, config) { 
     console.log("Error in retrieving data from server"); 
     console.log(data, status); 
    }); 
}; 
$scope.getLogins(); 

HTML：

<md-select ng-model="getLogins" ng-options="logins.id for logins in chooseLogins"> 
    <md-option value="{{logins.id}}">{{logins.name}}</md-option> 
</md-select>
