Appengine EofException：已关闭

Question

有人可以帮我解决这个问题吗？我正在尝试部署我的Appengine Java应用程序，并且在尝试使用Google登录时遇到了此问题 在本地，一切正常。所有URI都是正确的，并且在client_secrets.json中进行了正确配置。顺便说一句，我在gae控制台中没有任何可用的当前日志。它会在几个小时后更新。服务器尝试重定向到身份验证URL时会发生这种情况。因此，最后可见的日志是：

Answer 1

这是我的解决方案，我更改了get方法而未返回任何值

@RequestMapping(value ="/googleLogin", method = RequestMethod.GET) 
@ResponseStatus(value = HttpStatus.OK) 
public void glogin(HttpServletRequest request, HttpServletResponse response) { 
  try{ 
    credentialsManager.authRedirect(response); 
  } 
  catch(Exception e) { e.printStackTrace(); } 
  String res = "okgoogle"; 
  log.debug(res); 
}
