#GET请求
import httplib

try:
conn = httplib.HTTPConnection("www.baidu.com")
conn.request("GET", "/")
response = conn.getresponse()
print response.status, response.reason
print '-' * 40
headers = response.getheaders()
for h in headers:
print h
print '-' * 40
print response.msg
except Exception,e:
print e
finally:
if conn:
conn.close()

#POST请求
import httplib, urllib
conn = None
try:
params = urllib.urlencode({'name': 'qiye', 'age':22})
headers = {"Content-type": "application/x-www-form-urlencoded"
, "Accept": "text/plain"}
conn = httplib.HTTPConnection("www.baidu.com", 80, timeout=3)
conn.request("POST", "/login", params, headers)
response = conn.getresponse()
print response.getheaders() #获取头信
