部署应用程序时，我似乎收到此错误，但在本地主机上提供服务时却没有：
E 2012-08-21 18:03:46.914 HTTP Error 400: Bad Request Traceback (most recent call last): File "/base/python27_runtime/python27_lib/versions/third_party/webapp2-2.3/webapp2.py

生成此错误的代码位于此处（请原谅巨大的处理程序）：

else:
self.redirect('/register')
这就是造成它的具体原因：
streamm = (streamss[(streamss.find('.tv/')+ 4):])
check_if_life2 = self.check_if_live((streamss[(streamss.find('.tv/')+ 4):]))
它利用了顶部的函数“check_if_live”。作为一个完全的python菜鸟，我一生都无法弄清楚为什么这个错误是实时生成的，而不是在本地主机上生成的。
编辑：
我仍然无法让 API 工作。有趣的是，如果您在地址栏中调用 API，例如http://api.justin.tv/api/stream/list.json?channel=nasltv，它可以正常工作。但是一旦它接触到应用程序引擎，它就会失败。我只需要索引这个 API！啊!
