相信做過自動化運維的同學都用過API接口來完成某些動作。API是一套成熟系統所必需的接口，可以被其他系統或腳本來調用，這也是自動化運維的必修課。



本文主要介紹python中調用API的幾種方式，下面是python中會用到的庫。

- urllib2

- httplib2

- pycurl

- requests 

urllib2

import urllib2, urllib
github_url = 'https://api.github.com/user/repos'
password_manager = urllib2.HTTPPasswordMgrWithDefaultRealm()
password_manager.add_password(None, github_url, 'user', '***')
auth = urllib2.HTTPBasicAuthHandler(password_manager) # create an authentication handler
opener = urllib2.build_opener(auth) # create an opener with the authentication handler
urllib2.install_opener(opener) # install the opener... 
request = urllib2.Request(github_url, urllib.urlencode({'name':'Test repo', 'description': 'Some test repository'})) # Manual encoding required
handler = urllib2.urlopen(request)
print handler.read()
2. httplib2

import urllib, httplib2
github_url = '
h = httplib2.Http(".cache")
h.add_credentials("user", "******", "
data = urllib.urlencode({"name":"test"})
resp, content = h.request(github_url, "POST", data)
print content
3. pycurl

import pycurl, json
github_url = "
user_pwd = "user:*****"
data = json.dumps({"name": "test_repo", "description": "Some test repo"})
c = pycurl.Curl()
c.setopt(pycurl.URL, github_url)
c.setopt(pycurl.USERPWD, user_pwd)
c.setopt(pycurl.POST, 1)
c.setopt(pycurl.POSTFIELDS, data)
c.perform()
4. requests

import requests, json
github_url = "
data = json.dumps({'name':'test', 'description':'some test repo'}) 
r = requests.post(github_url, data, auth=('user', '*****'))
print r.json
以上幾種方式都可以調用API來執行動作，但requests這種方式代碼最簡潔，最清晰，建議采用。
