本文介绍Python自带库urllib2的最简版HTTPS请求示例，包括创建cookie处理器、HTTPS处理器，设置请求头，处理请求异常及响应读取。

urllib2是python自带的库，可以用作http client。下面这段代码是最简版的使用。

import os
import sys
import ssl
import cookielib
import urllib2
ssl._create_default_https_context = ssl._create_unverified_context    # 关闭ssl认证


def main(ip, port):

    # create a cookie jar and cookie handler
    cookie_jar = cookielib.LWPCookieJar()
    cookie_handler = urllib2.HTTPCookieProcessor(cookie_jar)

    httpsHandler = urllib2.HTTPSHandler(debuglevel = 1)
    https_opener = urllib2.build_opener(cookie_handler, httpsHandler)
    
    headers = {"Accept": "application/json"}
    targetUrl = "https://%s:%d/healthcheck" % (ip, port)
    
    request = urllib2.Request(url=targetUrl, headers=headers)

    try:
        response = https_opener.open(request)
    except Exception, e:
        print >>sys.stderr, "First request failed: %s" % e
        sys.exit(1)
    print response.read()
    

if __name__ == "__main__":
    main("127.0.0.1", 443)
