以下是学习笔记：
Get方法， 并且自定义header
# -* - coding: UTF-8 -* - import urllib2 request = urllib2.Request("http://www.baidu.com/") request.add_header('content-TYPE', 'application/x-www-form-urlencoded') response = urllib2.urlopen(request) print response.getcode() print response.geturl() print response.read()
post方法
# -* - coding: UTF-8 -* - import urllib2 import urllib request = urllib2.Request("http://passport.cnblogs.com/login.aspx") request.add_header('content-TYPE', 'application/x-www-form-urlencoded') data={"tbUserName":"test_username", "tbPassword":"test_password"} response = urllib2.urlopen(request, urllib.urlencode(data)) print response.getcode() print response.geturl() print response.read()
HTTPError
默认情况下，只要不是2XX的返回码，都会被当成错误对待。可以通过HTTPError来捕捉错误信息
import urllib2 url = "http://www.jnrain.com/go" try: response = urllib2.urlopen(url) print response.info() print response.read() except urllib2.HTTPError, e: print e.getcode() print e.reason print e.geturl() print "--" *100 print e.info() print e.read()
通过捕捉错误可以打印出详细的错误信息：
404 Not Found http://www.jnrain.com/go ------------------------- Server: nginx/1.4.1 Date: Wed, 19 Feb 2014 08:51:50 GMT Content-Type: text/html; charset=gb18030 Content-Length: 168 Connection: close <html> <head><title>404 Not Found</title></head> <body bgcolor="white"> <center><h1>404 Not Found</h1></center> <hr><center>nginx/1.4.1</center> </body> </html>
