python发送post和get请求

get请求：

使用get方式时，请求数据直接放在url中。

方法一、

import urllib

import urllib2

url = "http://192.168.81.16/cgi-bin/python_test/test.py?ServiceCode=aaaa"

req = urllib2.Request(url)

print req

res_data = urllib2.urlopen(req)

res = res_data.read()

print res

方法二、

import httplib

url = "http://192.168.81.16/cgi-bin/python_test/test.py?ServiceCode=aaaa"

conn = httplib.HTTPConnection("192.168.81.16")

conn.request(method="GET",url=url)

response = conn.getresponse()

res= response.read()

print res

post请求：

使用post方式时，数据放在data或者body中，不能放在url中，放在url中将被忽略。

方法一、

import urllib

import urllib2

test_data = {'ServiceCode':'aaaa','b':'bbbbb'}

test_data_urlencode = urllib.urlencode(test_data)

requrl = "http://192.168.81.16/cgi-bin/python_test/test.py"

req = urllib2.Request(url = requrl,data =test_data_urlencode)

print req

res_data = urllib2.urlopen(req)

res = res_data.read()

print res

方法二、

import urllib

import httplib

test_data = {'ServiceCode':'aaaa','b':'bbbbb'}

test_data_urlencode = urllib.urlencode(test_data)

requrl = "http://192.168.81.16/cgi-bin/python_test/test.py"

headerdata = {"Host":"192.168.81.16"}

conn = httplib.HTTPConnection("192.168.81.16")

conn.request(method="POST",url=requrl,body=test_data_urlencode,headers = headerdata) 

response = conn.getresponse()

res= response.read()

print res
