即使已安装cordova-plugin-whitelist，$ http的ionic也无法在实际设备上运行

Question

I am creating an ionic app that fetch json value from remote server using $http get. 我正在创建一个离子应用程序，该应用程序使用$ http get从远程服务器获取json值。 It displays the data when I run it on the browser but not on real Android device. 当我在浏览器上而不是在真正的Android设备上运行数据时，它将显示数据。 I also have cordova-plugin-whitelist installed already. 我也已经安装了cordova-plugin-whitelist 。

Here is my code on the index.html 这是我在index.html上的代码

<html>
  <head>
    <meta charset="utf-8">
    <meta name="viewport" content="initial-scale=1, maximum-scale=1, user-scalable=no, width=device-width">
    <meta http-equiv="Content-Security-Policy" content="default-src *; style-src 'self' 'unsafe-inline'; script-src 'self' 'unsafe-inline' 'unsafe-eval'">
    <title></title>

    <link href="lib/ionic/css/ionic.css" rel="stylesheet">
    <link href="css/style.css" rel="stylesheet">

    <!-- IF using Sass (run gulp sass first), then uncomment below and remove the CSS includes above
    <link href="css/ionic.app.css" rel="stylesheet">

    <!-- ionic/angularjs js -->
    <script src="lib/ionic/js/ionic.bundle.js"></script>

    <!-- cordova script (this will be a 404 during development) -->
    <script src="cordova.js"></script>

    <!-- your app's js -->
    <script src="js/app.js"></script>
    <script src="js/controllers.js"></script>

  </head>

  <body ng-app="starter">
    <ion-nav-view>
    </ion-nav-view>
  </body>
</html>

controller.js

.controller('ProductsCtrl', function($scope, $ionicModal, $timeout, $http,    $stateParams) {
      console.log("ProductCtrl: prod_id = " + $stateParams.prod_id);
      $scope.host = "xxxx";
      $http.get("http://"+ $scope.host +"/xxxx/xxxx.php?cat_id=" + $stateParams.prod_id)
      .then(function(response) {
        $scope.products = response.data;
      })
      .error(function(data, status, headers,config){
        console.log('data error');
      })
      .then(function(result){
        things = result.data;
      });
})

config.xml

As you can see in index.html I've put the <meta> tag as suggested on other post that I saw here 正如您在index.html中看到的那样，我已经按照在此处看到的其他文章中的建议放置了<meta>标记

<meta http-equiv="Content-Security-Policy" content="default-src *; style-src 'self' 'unsafe-inline'; script-src 'self' 'unsafe-inline' 'unsafe-eval'">

I also tried to uninstall and reinstall the cordova-plugin-whitelist but nothing has changed. 我也尝试卸载并重新安装cordova-plugin-whitelist但没有任何改变。

cordova plugin remove cordova-plugin-whitelist

cordova plugin add cordova-plugin-whitelist

These are the errors displayed on the console. 这些是控制台上显示的错误。 Mostly are just 404 like this: 大多只是这样的404：

Failed to load resource: net::ERR_NAME_NOT_RESOLVED

But this one is probably because of the <meta> .. 但这可能是因为<meta> ..

Refused to load the script 'http://localhost:35729/livereload.js?snipver=1' because it violates the following Content Security Policy directive: "script-src 'self' 'unsafe-inline' 'unsafe-eval'".
(anonymous function) @ localhost:8100/?ionicplatform=ios:98

Please help.. thanks in advance.. 请帮助..在此先感谢..

Answer 1

I use this as my meta tag and it handles all such things. 我将其用作元标记，它可以处理所有此类事情。 Try this a let me know it it works 试试这个让我知道它有效

 <meta http-equiv="Content-Security-Policy" content="default-src *; img-src *;style-src * &apos;unsafe-inline&apos;; script-src * &apos;unsafe-inline&apos; &apos;unsafe-eval&apos;">

Answer 2

I have found the answer last time but I'll just post it now. 我上次找到了答案，但我现在将其发布。 I usually run my android app using Ionic Lab but when I run my app from console ( ionic run android ), I've noticed this: 我通常使用Ionic Lab运行我的android应用程序，但是当我从控制台（ ionic run android ）运行我的应用程序时，我注意到了这一点：

"Using this version of Cordova with older version of corodva-android is being deprecated. Consider upgrading to cordova-android@5.0.0 or newer. " “不建议将此版本的Cordova与旧版本的corodva-android一起使用。请考虑升级到cordova-android@5.0.0或更高版本。”

so I just upgraded my cordova: 所以我刚升级了科尔多瓦：

cordova platform remove android
cordova platform add android@5.X.X

Then it worked finally. 然后终于奏效了。
