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

- urllib2

- httplib2

- pycurl

- requests?

urllib2
- Sample1

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()

??- Sample2

import?urllib2

url?=?'http://ems.vip.ebay.com/removeSIforcloud.cgi?ip='?+?ip

req?=?urllib2.Request(url)

req.add_header('IAF',abc.token_authiaas)

try:

????resp?=?urllib2.urlopen(req)

except?urllib2.HTTPError,?error:

????print?"Cannot?remove?service?instance!",?error

????sys.exit(1)

response?=?resp.read()

print?response

? - Sample3

import?urllib2,?urllib,?base64

url?=?"https://reparo.stratus.ebay.com/reparo/bootstrap/registerasset/"?+?rackid?+?"/"?+?asset

data?=?urllib.urlencode({

????????????????'reservedResource':'RR-Hadoop',

????????????????'resourceCapability':'Production',

????????????????'movetoironic':'False',

????????????????'output':'json'

????????})

print?"Bootstrap?Asset?jobs?starting?.............."

base64string?=?base64.encodestring('%s:%s'?%?(user,?passwd)).replace('\n',?'')

request?=?urllib2.Request(url,?data,?headers={"Authorization"?:?"Basic?%s"?%?base64string})

response?=?urllib2.urlopen(request).read()

response_json?=?json.loads(response)

response_status?=?response_json['status']

status_code?=?response_status['statusCode']

status?=?response_status['status']

message?=?response_status['message']???????????

print?status_code?,?status,?message

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。
