Python中两种方法实现模拟登陆的代码实例

import urllib.request

import urllib.parse

import http.cookiejar

#post的内容

values={

'logon.x':'linke',

'password':'xxxx',

'username':'xxxxx'

}

#登陆的地址

logUrl="http://192.168.32.112:8080/templates/index/hrlogon.do"

#构建cook

cook=http.cookiejar.CookieJar()

#构建openner

openner=urllib.request.build_opener(urllib.request.HTTPCookieProcessor(cook))

#添加headers

openner.addheaders = [('User-agent', 'Mozilla/5.0 (Windows NT 6.3; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/31.0.1650.63 Safari/537.36')]

r=openner.open(logUrl,urllib.parse.urlencode(values).encode())

#print(r.read().decode('gbk'))

r=openner.open("http://192.168.132.62:8080/kq/kqself/card/carddata.do?b_query=link")

print(r.read().decode('gbk'))
