推荐答案

假设服务器端 PHP 代码在成功登录后发送 302 重定向标头，您可以将这些代码添加到您的 doInBackground() 触发客户端重定向的方法(如果您使用的是 HTTP Client 4.1+).

Assuming that the server-side PHP codes are sending a 302 redirect header upon successful login, you can add these codes to your doInBackground() method to trigger a client-side redirect (if you are using HTTP Client 4.1+).

DefaultHttpClient client = new DefaultHttpClient();
client.setRedirectStrategy(new LaxRedirectStrategy());
