所以我已经在本地主机上测试了我的 Android 应用程序，没有任何问题。现在我尝试将 php 文件以及我在本地主机上使用的数据库上传到我的在线网站上。 我已经阅读了以下内容 Cookies sent by server 但我没有看到发送任何 cookie。
我可以看到以下内容

我的在线服务器上的 PHP:

我正在尝试测试的链接 http://busted.byethost16.com/Andriod/login_with_route.php .side问题，为什么会变成 http://busted.byethost16.com/Andriod/login_with_route.php?i=1 当我收到回复时？
最佳答案
输入您的服务器代码顶部
ob_start("ob_tidyhandler");
或者将其放在您的代码中
header("Content-type: application/json");
echo json_encode($response);
关于javascript - Android在线服务器接收JavaScript响应而不是Json？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/39382765/
