$http 在 Ionic / AngularJS 应用程序的 iOS 8.2 中不起作用

Question

以下代码适用于 iOS 9.3++ 的 Ionic 应用程序，但不适用于 iOS 8.2：

  $http({
      method: 'POST',
      url: 'https://example.com',
      data: {username: username, password: password }
  }).then(function(result) {
     //I wish!
  },function(error) {
    //unfortunately we end up here for iOS 8.2, but not for 9.3 or greater
  });

我已验证两个版本都将 POST 数据发送到服务器，并且服务器会生成正确的响应。

iOS 8.3 抛出错误：

Failed to load resource: The network connection was lost.

我怀疑某种浏览器设置/权限/CORS 问题，但在 SO 或 google 上没有找到解决方案。

我的服务器 (PHP) 设置为接收这样的 ajax 请求：

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');
}

//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); 
}

//processing code goes here and a proper $response is created
echo json_encode($response);

尝试在您的 http 请求中添加这一行
