Question

这里实际上是完整的错误：错误：[ngRepeat：dupes]不允许在转发器中重复。使用＆＃39;跟踪＆＃39;表达式以指定唯一键。中继器：红毛猩猩，重复键：字符串：＆＃34;，重复值：＆＃34;

这是我的HTML代码：

<ion-view view-title="Daftar Orang">
  <ion-content>
    <ion-list>
      <ion-item ng-repeat="orang in orangs">
        {{orang.nama}}
      </ion-item>
    </ion-list>
  </ion-content>
</ion-view>

这是我的角度控制器：

.controller('OrangCtrl', function($scope, $http, $ionicLoading, $ionicHistory) {

  $ionicHistory.nextViewOptions({
    disableBack: true
  });

  //loading
  $scope.show = function() {
    $ionicLoading.show({
      template: '<ion-spinner icon="android"></ion-spinner><br>Harap Tunggu'
    }).then(function(){
       console.log("The loading indicator is now displayed");
    });
  };
  $scope.hide = function(){
    $ionicLoading.hide().then(function(){
       console.log("The loading indicator is now hidden");
    });
  };  
    $scope.show();
    $http({
        url: "http://localhost/android_server/orang/read?key=vr46",
        method: "GET",
        data: {}
    })
    .then(function(response) {
        $scope.myData = response.data;
        $scope.hide();
          $scope.orangs = angular.toJson($scope.myData.data);
          console.log('Response Data', $scope.orangs);

    });   

})

这是我的codeigniter rest_server控制器：

    <?php

require(APPPATH.'libraries/REST_Controller.php');

class Orang extends REST_Controller {

    public function __construct(){
        parent::__construct();
            date_default_timezone_set("Asia/Jakarta");

        if (isset($_SERVER['HTTP_ORIGIN'])) {
            header("Access-Control-Allow-Origin: {$_SERVER['HTTP_ORIGIN']}");
            header('Access-Control-Allow-Credentials: true');
            header('Access-Control-Max-Age: 86400');    // cache for 1 day
        }

        // Access-Control headers are received during OPTIONS requests
        if ($_SERVER['REQUEST_METHOD'] == 'OPTIONS') {

            if (isset($_SERVER['HTTP_ACCESS_CONTROL_REQUEST_METHOD']))
                header("Access-Control-Allow-Methods: GET, POST, OPTIONS");         

            if (isset($_SERVER['HTTP_ACCESS_CONTROL_REQUEST_HEADERS']))
                header("Access-Control-Allow-Headers:        
                {$_SERVER['HTTP_ACCESS_CONTROL_REQUEST_HEADERS']}");

            exit(0);
        }           


    }

    function read_get()
    {
        $data = $this->db->order_by('id', 'DESC')->get('orang')->result();
        if($data){
            $response['data'] = $data;
            $response['status'] = 1;
        }else{
            $response['status'] = 0;
            $response['message'] = 'Data tidak ada';
        }   
        $this->response($response);
    }
}

我使用codeigniter rest服务器来获取数据。

按$ index＆＃39;添加＆＃39;你的ng-repeat。

$list = [
    ["Name" => "John", "Gender" => "M"],
    ["Name" => "Doe", "Gender" => "M"],
    ["Name" => "Sara", "Gender" => "F"]
];

$csvArray = ["header" => implode (",", array_keys($list[0]))] + array_map(function($item) {
    return implode (",", $item);
}, $list);

file_put_contents($filename, implode ("\n", $csvArray));

Angular并不喜欢它的中继器中的重复键。这将通过他们的索引来跟踪它们。请参阅more detailed explanation here。
