>>> importhttplib 

>>> conn = httplib.HTTPConnection("www.python.org") 

>>> conn.request("GET","/index.html") 

>>> r1 =conn.getresponse() 

>>> printr1.status, r1.reason 

200 OK 

>>> data1 = r1.read() 

>>> conn.request("GET","/parrot.spam") 

>>> r2 =conn.getresponse() 

>>> printr2.status, r2.reason 

404 Not Found 

>>> data2 = r2.read() 

>>> conn.close()

200 OK 

>>> data = res.read() 

>>> printlen(data) 

0

>>> data == '' 

True

>>> importhttplib, urllib 

>>> params = urllib.urlencode({'spam':1,'eggs':2,'bacon':0}) 

>>> headers = {"Content-type":"application/x-www-form-urlencoded", 

...            "Accept": "text/plain"} 

>>> conn = httplib.HTTPConnection("musi-cal.mojam.com:80") 

>>> conn.request("POST","/cgi-bin/query", params, headers) 

>>> response = conn.getresponse() 

>>> printresponse.status, response.reason 

200 OK 

>>> data = response.read() 

>>> conn.close()

以下是Python3中使用urllib2的方法，更方便
