App Engine – 在/ _ah / openid_verify上发生间歇性500错误

使用Google openidlogin我的应用程序时，出现间歇性错误。

他们发送的链接是http://www.example.com/_ah/login_redir?claimid=www.google.com/accounts/o8/id&continue=http://www.example.com/login2?returl%253Dhttp%25253A%25252F%25252Fwww.example.com%25252Ftest-list-8 。

然后当他们授予访问我的应用程序，有时有一个500错误的url：

500错误甚至不出现在我的日志中。 这似乎发生了约5-10％的login。

Answer 1

对于错误500意味着 – 找不到页面/ ID /密码

同样，您需要再次使用openID进行检查，或者仅为相同的testing目的创build一个Google ID

Answer 2

在你的service（）方法中，通过包装你的doGet（）来捕获和输出exception，如下所示：

 . . . try { doGet(request,response); } catch (Throwable e) { writer.println("<pre>"); e.printStackTrace(writer); writer.println("</pre>"); } . . .
