一、工具包urlllib和urllib2导入；
# GET和POST请求需要工具包urllib import urllib # 导入工具包 import urllib2
二、a）爬取网站对应的源码
# 通过资源定位符获取网页对象，通过read方法返回网页的源码 response = urllib2.urlopen("http://www.baidu.com") print response.read()
b）将其写得规范一点，则如下所示
# 构造request请求实例 request = urllib2.Request("http://www.baidu.com") response = urllib2.urlopen(request) print response.read()
三、构造POST请求
# POST请求 values = {"username": "geek", "password": "**********"} # 或者 values = {} values["username"] = "geek" values["password"] = "**********" # 将字典编码 data = urllib.urlencode(values) url = "https://passport.csdn.net/account/login?from=http://my.csdn.net/my/mycsdn" request = urllib2.Request(url, data) response = urllib2.urlopen(request) print response.read()
四、构造GET请求
# GET请求 values = {"username": "geek", "password": "**********"} data = urllib.urlencode(values) url = "https://passport.csdn.net/account/login?from=http://my.csdn.net/my/mycsdn" request = url + "?" + data response = urllib2.urlopen(request) print response.read()
