在网址末尾添加“ /”会导致重定向发生，因为您的服务器喜欢以“
/”结尾的网址。服务器将您重定向到的URL完全支持POST，但是当客户端根据setRedirecting（）调用的行为运行时，客户端将执行GET请求（cURL与-
L开关执行相同的操作）解决方法是要么URL末尾的’/’，或者您自己从响应中获取Location标头，然后手动启动另一个POST请求。
这可以在wireshark中观察到。您可以通过尝试使用浏览器对URL附加一个斜杠的GET请求来测试该理论。这将导致浏览器得到405。这是Android的固定代码，此代码使用简单的修复方法，即在URL后面附加一个“
/”（尚未投入生产）：
