Question

以下代码适用于iOS版本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
  });

我已经确认两个版本都将POST数据发送到服务器，服务器会生成正确的响应。

iOS 8.3引发错误：

Failed to load resource: The network connection was lost.

我怀疑某种浏览器设置/权限/ CORS问题，但未在SO或Google上找到解决方案。

我的服务器（PHP）设置为接收如下的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请求中添加此行

标题：{＆＃39;内容类型＆＃39;：＆＃39; application / x-www-form-urlencoded＆＃39; }

$ http在Ionic / AngularJS app中的iOS 8.2中无效
