$ http在Ionic / AngularJS應用中的iOS 8.2中不起作用

Question

以下代碼在適用於iOS 9.3 ++版的Ionic應用程序中有效，但不適用於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
  });

我已經驗證了兩個版本都將POST數據發送到服務器，並且服務器生成了正確的響應。

iOS 8.3引發錯誤：

Failed to load resource: The network connection was lost.

我懷疑某種瀏覽器設置/權限/ CORS問題，但尚未在SO或Google上找到解決方案。

我的服務器（PHP）設置為接收如下ajax請求：

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);

嘗試在您的http請求中添加此行

標頭：{'Content-Type'：'application / x-www-form-urlencoded'}
