httplib和urllib2常用方法

　　都是几年前用过的，现在翻出来记录一下。

import httplib
import urllib2
import socket

##--------------------------------------------------------用httplib进行GET请求
conn=httplib.HTTPConnection('172.22.31.40',8080)##如果要走代理，那这里自然要改为代理服务器的地址
conn.request("GET","/cloud/index.php")
result=conn.getresponse()
print result.read()
resultStatus=result.status
print resultStatus
conn.close()

conn=httplib.HTTPConnection('www.cnblogs.com',80)
conn.request("GET","/idbeta/default.html")
result=conn.getresponse()
print result.read()
resultStatus=result.status
print resultStatus
conn.close()

##--------------------------------------------------------用httplib进行POST请求
conn=httplib.HTTPConnection('172.22.131.40',80)
##一般重点关注真实包的"Content-type"，例如"application/x-www-form-urlencoded"等；而data则根据真实抓包情况来模拟，需要url编码的用urllib.urlencode
header1 = {"Content-type": "application/x-www-form-urlencoded", "User-Agent" : "test"}
data1 = '''{
   "audit_control_list" : [],
   "ws" : [
      "base_setting",
   ],
   "xp_fix" : []
} '''
url1='/api/getconf.json?mid=ebcd32d5f68e404db1ccc8ff2dacb360&ver=1.0'
conn.request('POST',url1,body=data1,headers=header1)
result=conn.getresponse()
content=result.read()
print content
conn.close()

##发送multipart/form-data请求的例子
conn=httplib.HTTPConnection('172.22.131.40',80)
header2={"Content-Type":"multipart/form-data; boundary=----------------------------2bb6caed7d98"}
data2 = '''------------------------------2bb6caed7d98
Content-Disposition: form-data; name="em"
md5s=92f44e405db16ac55d97e3bfe3b132fa+04c5d2b4da9a0f3fa8a45702d4256cee42d8c48d	452608	\WINDOWS\syswow64\windowspowershell\v1.0\powershell.exe	1

------------------------------2bb6caed7d98--
'''
url2='/cloudquery.php'
conn.request("POST",url2,body=data2,headers=header2)
result=conn.getresponse()
resultStatus=result.status
##获取请求的页面内容
content=result.read()
print content
print result.status,result.reason
##关闭连接
conn.close()

##--------------------------------------------------------用urllib2进行GET请求
##直接open就是GET
url="http://www.cnblogs.com/idbeta/default.html"
response =urllib2.urlopen(url)
print response.read()
##--------------------------------------------------------用urllib2进行POST请求
url="http://172.22.131.40/api/getconf.json?mid=ebcd32d5f68e404db1ccc8ff2dacb360&ver=1.0"
header1 = {"Content-type": "application/x-www-form-urlencoded", "User-Agent" : "test"}
data1 = '''{
   "audit_control_list" : [],
   "base_config" : [],
   "data_linkage" : [],
   "md" : [],
   "nac_linkage" : [],
   "neteye" : [],
   "p2p_setting" : [],
   "safe_control_list" : [],
   "sd" : [ "sd_settings", "rp_settings" ],
   "ui" : [],
   "ws" : [
      "base_setting",
      "popwnd_setting",
      "startup_assistant",
      "safe_protect",
      "leak_repair"
   ],
   "xp_fix" : []
} '''
req = urllib2.Request(url, data1, header1)  # 发送请求同时传data表单，这个是字典方式
response = urllib2.urlopen(req)  #接受反馈的信息
the_page = response.read()  #读取反馈的内容
print the_page

##--------------------------------------------------------urllib2设置超时时间
##方法一  全局设置
socket.setdefaulttimeout(1);秒
##或
urllib2.socket.setdefaulttimeout(1)
##方法二  urllib2.urlopen加入timeout参数
urllib2.urlopen(url,timeout=1)
##--------------------------------------------------------urllib2设置代理
proxy = urllib2.ProxyHandler({"http" : 'http://172.22.31.85:808'})
urllib2.install_opener(urllib2.build_opener(proxy))
url="http://www.cnblogs.com/idbeta/default.html"
response =urllib2.urlopen(url)
print response.read()

　　除了上面所说的，还有httplib2、pycurl、requests等等都是和http相关的，用法大同小异，大家去各自官网看介绍就可以了，可见python的第三方库实在有点太多了啊。
