python http請求庫

Python中http請求方法庫彙總

一、python自帶庫----urllib2

python自帶庫urllib2使用的比較多，簡單使用如下：

import urllib2

response = urllib2.urlopen('http://localhost:8080/jenkins/api/json?pretty=true')

print response.read() 

簡單的get請求

import urllib2

import urllib

post_data = urllib.urlencode({})

response = urllib2.urlopen('http://localhost:8080/, post_data)

print response.read()

print response.getheaders() 

這就是最簡單的urllib2發送post例子。代碼比較多

二、python自帶庫--httplib

httplib是一個相對底層的http請求子產品，urlib就是基于httplib封裝的。簡單使用如下：

1 2 3 4 5 6 7 8 9 10

import httplib conn  = httplib.HTTPConnection( "www.python.org" ) conn.request( "GET" ,  "/index.html" ) r1  = conn.getresponse() print r1.status, r1.reason data1  = r1.read() conn.request( "GET" ,  "/parrot.spam" ) r2  = conn.getresponse() data2  = r2.read() conn.close()

get請求

post請求

1 2 3 4 5 6 7 8 9

import httplib, urllib params  = urllib.urlencode({ '@number' :  12524 ,  '@type' :  'issue' ,  '@action' :  'show' }) headers  = { "Content-type" :  "application/x-www-form-urlencoded" ,  "Accept" :  "text/plain" } conn  = httplib.HTTPConnection( "bugs.python.org" ) conn.request( "POST" , "", params, headers) response  = conn.getresponse() data  = response.read() print data conn.close()

三、第三方庫--requests

發請get請求

1	print requests.get('http: //localhost :8080).text

post請求

1 2 3

payload  = { 'key1' :  'value1' ,  'key2' :  'value2' } r  = requests.post( "http://httpbin.org/post" , data = payload) print r.text

認證：

1 2 3 4 5

url  = 'http://localhost:8080' r  = requests.post(url, data = {}, auth = HTTPBasicAuth( 'admin' ,  'admin' )) print r.status_code print r.headers print r.reason

比urllib2更簡單，且requests自帶json解析。

import urllib params  = urllib.urlencode({key:value,key:value}) resultHtml  = urllib.urlopen( '[API or 網址]' ,params) result  = resultHtml.read() print result
