python - 开发服务器 HTTP 错误 403 : Forbidden

Question

从 1.7.5 更新后(一切正常)我在尝试通过本地主机打开任何网站时收到 HTTP 错误 403:禁止访问。奇怪的是，我在家里的设置与在工作中的设置几乎相同，一切都在那里工作……可能是我们在工作中使用的代理服务器的问题，因为这是我能想到的唯一区别？这是我得到的错误日志，所以如果有人知道发生了什么，请帮忙(;

此外，启动器在关闭时会抛出错误:

Answer 1

在使用 Google App Engine Launcher 1.8.6 使用代理服务器时，我的 MacOSX 遇到了同样的问题。显然“urllib2.py”上的“proxy_bypass”存在问题。

有两种可能的解决方案:

1. 降级到 1.7.5，但是，谁想降级？

2. 编辑“[GAE Instalattion path]/google/appengine/tools/appengine_rpc.py”并查找显示以下内容的行

   opener.add_handler(fancy_urllib.FancyProxyHandler())

在我的电脑中是第 578 行，然后在该行的开头放置一个井号 (#)，如下所示:

`#opener.add_handler(fancy_urllib.FancyProxyHandler())`

保存文件，停止然后重新启动您的应用程序。现在 dev_appserver.py 根本不应该尝试使用任何代理服务器。

如果您的应用程序使用任何外部资源，如 SOAP Web 服务或类似的东西，并且您无法在没有代理服务器的情况下访问服务器，那么您将不得不降级。请记住，外部 javascript 文件(如 facebook SDK 或类似文件)是从您的浏览器加载的，而不是从您的应用程序加载的。

因为我没有使用任何外部 REST 或 SOAP 服务，所以它对我有用!

希望它也对您有用。
