Python 运行dev_appserver.py时发生永久移动错误

我正在尝试基本的helloworld示例（），每次尝试使用dev_appserver.py测试代码时，都会收到

HTTP错误301:Moved permanually

错误

我所拥有的两个文件是完全从developers.google.com网站复制和粘贴的。 我已经包括了dev_appserver.py在PATH和PYTHONPATH中的位置

我在Linux上用Python2.7.3和appengine v1.8.4运行它

当我运行此命令时，终端上的输出是

[verma@localhost python]$ dev_appserver.py helloworld/

我有一种感觉，我错过了一些非常基本的东西，但却找不到。顺便说一句，这在几天前是有效的，我不记得我做了什么愚蠢的事情来打破这一点：-（

似乎dev_apserver需要每隔一段时间联系互联网上的谷歌应用引擎服务器（即使你不要求它检查更新）。我遇到的问题是，它在代理后无法访问google服务器（即使我已正确导出http_代理和https_代理）

当我使用直接连接到互联网的有线网络时，我一点问题也没有

一旦dev_appserver“调用home”，它将在代理后继续工作几天而不会出现问题，然后我又遇到了这个问题

在过去，我也注意到在连接wifi时出现类似的行为

似乎dev_appserver在没有代理的有线网络上工作得最好

这仅仅是基于我的观察；如果有人能对这个问题给出明确的答案，那就太好了。

快速解决您的问题

打开文件[GAE安装路径]/google/appengine/tools/appengine_rpc.py”

转到578线

注释掉下面一行

---

#opener.add_handler（fancy_urllib.FancyProxyHandler（））

这个问题运气好吗？我在这里遇到了完全相同的问题。@DavidDai刚刚回答了我自己的问题。似乎dev_appserver不喜欢代理。当你想尝试你的应用程序时，这是有效的。但是如果你使用“appcfg.py update”“，如果您使用代理，则无法访问网络。使用google appengine 1.9.18，行号现在为595
