谷歌应用程序引擎的urllib错误&；python。[Errno 11003]getaddrinfo失败

提前谢谢你的帮助

我想获取网站的内容，所以我使用

urllib.urlopen（url）

如果我使用Google App Engine Launcher，运行应用程序，浏览

http://localhost:8082

，它工作得很好。 但如果我指定应用程序的地址和端口：

python `"D:\Program Files\Google\google_appengine\dev_appserver.py" -p 8082 -a 10.96.72.213 D:\pagedemon\videoareademo`

有点不对劲：

Traceback (most recent call last):
File "D:\Program Files\Google\google_appengine\google\appengine\ext\webapp\_webapp25.py", line 701, in __call__
  handler.get(*groups)
File "D:\pagedemon\videoareademo\home.py", line 76, in get
  wp = urllib.urlopen(url)
File "C:\Python27\lib\urllib.py", line 84, in urlopen
  return opener.open(url)

  return getattr(self, name)(url)

  response = self._conn.getresponse()
File "D:\Program Files\Google\google_appengine\google\appengine\dist\httplib.py", line 222, in getresponse
  deadline=self.timeout)

  return rpc.get_result()

  return self.__get_result_hook(self)

  raise DownloadError(str(err))
DownloadError: ApplicationError: 2 [Errno 11003] getaddrinfo failed

最奇怪的是当我更改url表单“

http://localhost:8080

“到”

http://127.0.0.1:8080

“，它工作得很好

我在谷歌上搜索了很多，但没有找到任何好的解决方案。希望能得到一些帮助！

另外，我没有配置任何代理。IE运行良好。

您的系统不一定知道本地主机应该解析为127.0.0.1。您可能需要在主机文件中输入一个条目。在Windows上，它位于

C:\Windows\System32\drivers\etc\hosts

感谢您的帮助！但是为什么我从GoogleAppEngineLauncher开始的应用程序可以很好地工作呢？我的系统必须知道localhost应该解析127.0.0.1，否则在IE中浏览不会显示tomcat页面。对吗？
