python中的HTTPConnection请求socket.gaierror

Question

我在尝试通过发送'GET'HTTP请求来检索XML时遇到错误.

from httplib import HTTPConnection
import urllib

params = urllib.urlencode({'sK': 'test', 'sXML': 1})
httpCon = HTTPConnection("http://www.podnapisi.net",80)
httpCon.request('GET', '/en/ppodnapisi/search',params)
r1 = httpCon.getresponse()

这是我得到的错误:

.....
File "C:\Python27\lib\socket.py", line 553, in create_connection
for res in getaddrinfo(host, port, 0, SOCK_STREAM):
socket.gaierror: [Errno 11004] getaddrinfo failed

我试图在这里检索的XML

我该如何解决这个错误？

提前致谢 ...

http://HTTPConnection构造函数中没有scheme():

httpCon = HTTPConnection("www.podnapisi.net",80)

它已经知道它是HTTP,它是一个HTTPConnection对象:)
