Question

我正在尝试基本的helloworld示例（https://developers.google.com/appengine/docs/python/gettingstartedpython27/helloworld），每当我尝试使用dev_appserver.py

尝试测试代码时，都会出现HTTP Error 301: Moved Permanently错误

我所拥有的2个文件完全从developers.google.com网站复制并粘贴。我已经包含了dev_appserver.py在PATH和PYTHONPATH中的位置

我在Linux上使用python 2.7.3和appengine v1.8.4

运行它

运行时终端上的输出是......

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

我有一种感觉，我错过了一些非常基本但却找不到的东西。顺便说一下，这是几天前的工作，我不记得做任何愚蠢的事情来打破这个： - （

解决问题的快速解决方案。

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

转到第578行

注释掉以下一行

#openner.add_handler（fancy_urllib.FancyProxyHandler（））

Answer 2

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服务器后面无法访问谷歌服务器（即使我已正确导出http_proxy和https_proxy）。

当我使用直接连接到互联网的有线网络时，我完全没有问题。

一旦dev_appserver'被叫回家'，它将继续在代理后面继续工作几天，然后我再次遇到这个问题。

过去我也注意到在wifi上连接时的类似行为。

似乎dev_appserver在没有代理的有线网络上效果最好。

这完全基于我的观察;如果有人能对这个问题给出明确的答案，那将会很棒。

运行dev_appserver.py时发生永久移动错误
