Python3处理HTTP请求的包：http.client，urllib，urllib3，requests
其中，http 比较 low-level，一般不直接使用
urllib更 high-level一点，属于标准库。urllib3跟urllib类似，拥有一些重要特性而且易于使用，但是属于扩展库，需要安装
requests 基于urllib3 ，也不是标准库，但是使用非常方便
个人感觉，如果非要用标准库，就使用urllib。如果没有限制，就用requests
# import http.client
# http_client = http.client.HTTPConnection('localhost',8080,timeout=10)
# http_client.request('get','/jenkins/api/json?pretty=true')
# response = http_client.getresponse()
# print(response.status)
# print(response.read())
# import urllib.request
# response = urllib.request.urlopen('http://localhost:8080/jenkins/api/json?pretty=true')
# print(response.status)
# print(response.read())
# import urllib3
# response = urllib3.PoolManager().request('get','http://localhost:8080/jenkins/api/json?pretty=true')
# print(response.status)
# import requests
# response = requests.get('http://localhost:8080/jenkins/api/json?pretty=true')
# print(response.status_code)
# print(response.text)
# print(response.json())
# print(response.reason)
import requests
from requests.auth import HTTPBasicAuth
response = requests.post('http://localhost:8080/jenkins/job/check_python_version/build',auth=('admin','wangmin'))
print (response.status_code)
print (response.reason)
print(response.headers)
