Web客户端访问

1、获取web页面

#coding:utf-8
import sys,urllib2

req=urllib2.Request(sys.argv[1])
fd=urllib2.urlopen(req)
while 1:
    data=fd.read(1024)
    if not len(data):
        break
    print data

2、GET提交数据

#coding:utf-8

import sys.urllib,urllib2

def addGETdata(url,data):
    return url+‘?‘+urllib.urlencode(data)

code=sys.argv[1]
url=addGETdata(‘http://www.baidu.com/xx.php‘,[(‘id‘,code)])

print "URL:",url
req=urllib2.Request(url)
fd=urllib2.urlopen(req)
while 1:
    data=fd.read(1024)
    if not len(data):
        break
    print data

3、POST提交数据

#coding:utf-8

import sys.urllib,urllib2

code=sys.argv[1]
url="http://www.baidu.com/xx.php"
data=urllib.urlencode([(‘id‘,code)])
req=urllib2.Request(url)
fd=urllib2.urlopen(req)

while 1:
    data=fd.read(1024)
    if not len(data):
