提前感谢您的帮助!

我想获取网站的内容,所以我使用urllib.urlopen(url)

set url='http://localhost:8080'(tomcat page)

如果我使用 Google App Engine Launcher,运行应用程序,浏览 http://localhost:8082 ,它运行良好。 但是,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`

就会出现问题:

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)
File "C:\Python27\lib\urllib.py", line 205, in open
  return getattr(self, name)(url)
File "C:\Python27\lib\urllib.py", line 343, in open_http
  errcode, errmsg, headers = h.getreply()
File "D:\Program Files\Google\google_appengine\google\appengine\dist\httplib.py", line 334, in getreply
  response = self._conn.getresponse()
File "D:\Program Files\Google\google_appengine\google\appengine\dist\httplib.py", line 222, in getresponse
  deadline=self.timeout)
File "D:\Program Files\Google\google_appengine\google\appengine\api\urlfetch.py", line 263, in fetch
  return rpc.get_result()
File "D:\Program Files\Google\google_appengine\google\appengine\api\apiproxy_stub_map.py", line 592, in get_result
  return self.__get_result_hook(self)
File "D:\Program Files\Google\google_appengine\google\appengine\api\urlfetch.py", line 365, in _get_fetch_result
  raise DownloadError(str(err))
DownloadError: ApplicationError: 2 [Errno 11003] getaddrinfo failed

最奇怪的事情是当我将 url 形式“http://localhost:8080”更改为“http:// /127.0.0.1:8080”,效果很好!

我google了很多,但没有找到任何好的解决方案。希望得到一些帮助! 另外,我没有配置任何 proxy.IE 运行良好。

Thanks for your help in advance!

I want to get contents of a website, so I use urllib.urlopen(url).

set url='http://localhost:8080'(tomcat page)

If I use Google App Engine Launcher, run the application, browse http://localhost:8082 , it works well.
But if I specify the address and port for the application:

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

there's something wrong:

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)
File "C:\Python27\lib\urllib.py", line 205, in open
  return getattr(self, name)(url)
File "C:\Python27\lib\urllib.py", line 343, in open_http
  errcode, errmsg, headers = h.getreply()
File "D:\Program Files\Google\google_appengine\google\appengine\dist\httplib.py", line 334, in getreply
  response = self._conn.getresponse()
File "D:\Program Files\Google\google_appengine\google\appengine\dist\httplib.py", line 222, in getresponse
  deadline=self.timeout)
File "D:\Program Files\Google\google_appengine\google\appengine\api\urlfetch.py", line 263, in fetch
  return rpc.get_result()
File "D:\Program Files\Google\google_appengine\google\appengine\api\apiproxy_stub_map.py", line 592, in get_result
  return self.__get_result_hook(self)
File "D:\Program Files\Google\google_appengine\google\appengine\api\urlfetch.py", line 365, in _get_fetch_result
  raise DownloadError(str(err))
DownloadError: ApplicationError: 2 [Errno 11003] getaddrinfo failed

The strangest thing is when I change the url form "http://localhost:8080" to "http://127.0.0.1:8080", it works well!

I googled a lot, but I didn't find any good solutions.Hoping for some help!
Also, I didn't configure any proxy.IE works well.

您的系统不一定知道 localhost 应解析为 127.0.0.1。您可能需要将一个条目放入主机文件中。在 Windows 上,它位于 C:\Windows\System32\drivers\etc\hosts

Your system doesn't necessarily know that localhost should resolve to 127.0.0.1. You might need to put an entry into your hosts file. On Windows, it's located at C:\Windows\System32\drivers\etc\hosts
