python urllib2使用心得

1、http GET请求

过程：获取返回结果，关闭连接，打印结果

f = urllib2.urlopen(req, timeout=10)the_page = f.read()f.close()print the_page

2、http GET请求 + 包头

paras = "Token=1234567890;Uuid=0987654321"url = http://www.cnblogs.com/shhnwangjiansend_headers = {"Cookie": paras, "User-Agent": "shhnwangjian", "Content-Type": "application/json"}req = urllib2.Request(url, headers=send_headers)  # 生成页面请求的完整数据f = urllib2.urlopen(req, timeout=10)  # 发送页面请求the_page = f.read()f.close()print the_page

3、http GET请求 + 包头，处理返回响应包头

paras = "Token=1234567890;Uuid=0987654321"send_headers = {"Cookie": paras, "User-Agent": "shhnwangjian", "Content-Type": "application/json"}url = http://www.cnblogs.com/shhnwangjianreq = urllib2.Request(url, headers=send_headers) f = urllib2.urlopen(req, timeout=10) response_head = f.info().getheader("Content-Type")  # 获取返回包头中Content-Type内容print response_headf.close()

4、http POST请求

postdata = urllib.urlencode({"username": "test", "password": "123456", "type": "Z"})f = urllib2.urlopen(url, postdata, timeout=10)the_page = f.read()f.close()print the_page

5、http POST请求 + 包头

postdata = urllib.urlencode({"username": "test", "password": "123456", "type": "Z"})paras = "Token=1234567890;Uuid=0987654321"url = http://www.cnblogs.com/shhnwangjiansend_headers = {"Cookie": paras, "User-Agent": "shhnwangjian", "Content-Type": "application/json"}req = urllib2.Request(url, headers=send_headers)  # 包头f = urllib2.urlopen(req, postdata, timeout=10)the_page = f.read()f.close()print the_page

6、http POST请求 + 包头，处理返回响应包头

postdata = urllib.urlencode({"username": "test", "password": "123456", "type": "Z"})paras = "Token=1234567890;Uuid=0987654321"url = http://www.cnblogs.com/shhnwangjiansend_headers = {"Cookie": paras, "User-Agent": "shhnwangjian", "Content-Type": "application/json"}req = urllib2.Request(url, headers=send_headers)  # 包头f = urllib2.urlopen(req, postdata, timeout=10)response_head = f.info().getheader("Cookie")  # 获取返回包头中Cookie内容print response_headf.close()

7、http post 请求，json数据包

send_headers = {"User-Agent": "shhnwangjian", "Content-Type": "application/json"}url = http://www.cnblogs.com/shhnwangjianbody = json.dumps({	"version": 1,	"sblx": "1",	"yjxx": "wangjian_AUTH",	"token": token,	"filemd5": "",	"crc": 123})req = urllib2.Request(url, data=body, headers=send_headers)f = urllib2.urlopen(req, timeout=2)the_page = f.read()f.close()

8、基于Basic access authentication的http请求，如调用RabbitMQ API接口

实现方式一：请求头中添加Authorization

Basic access authentication介绍:

import base64import urllib2url = http://ip:port/api/channelsbasicpwd = base64.b64encode("guest:guest")  # 账号密码send_headers = {"User-Agent": "TEST", "Content-Type": "application/json", "Authorization": "Basic %s" % basicpwd}req = urllib2.Request(url, headers=self.head)f = urllib2.urlopen(req, timeout=6)the_page = f.read()f.close()

实现方式二：http://guest:guest@ip:port/api/channels
