Android在线服务器接收JavaScript响应而不是Json - Android online server receiving JavaScript response instead of Json?

所以我在我的本地主机上测试了我的Android应用程序，没有任何问题。现在我正试图在我的在线网站上上传php文件以及我在本地主机上使用的数据库。我已经阅读了服务器发送的以下cookie但是我没有看到任何cookie发送。

我可以看到下面的

我要测试的链接http://busted.byethost16.com/Andriod/login_with_route.php附带问题，为什么会变成http://busted.byethost16.com/Andriod/login_with_route.php?i=1我什么时候能得到回复?

put in your server code

ob_start("ob_tidyhandler");

或者放到你的代码中

header("Content-type: application/json");
echo json_encode($response);

我切换到另一个免费托管网站，现在我的php工作，我得到正确的响应:

我的PHP代码仍然是相同的。所以主机服务出了什么问题，导致了不必要的响应。如果有人知道原因，请告诉我。
