#GET请求
import httplib
conn = None
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() #获取头信息
    print response.status
    print response.read()
except Exception, e:
    print e
finally:
    if conn:
        conn.close()
