获取cookie里面的sessionid

做接口的时候我们需要获取一个令牌，类似于token以及sessionid这样的签名，也可以说是一个令牌。

import urllib.request, urllib.parse, urllib.error
import http.cookiejar
class Cookie_login:
    def cookie_login(self):
 
        url = "http://192.168.110.85:8488/motorcade/ac/login"
        params = {"username":"","password":"aec60231d83fe6cf81444bc536596887,bfff2dd4f1b310eb0dbf593bd83f94dd8d34077e","verifycode":"","redirectUrl":"../../home.html"}
        # 获取cookie
        postdata = urllib.parse.urlencode(params).encode()
        cookie_filename = 'cookie.txt'
        cookie = http.cookiejar.MozillaCookieJar(cookie_filename)
        handler = urllib.request.HTTPCookieProcessor(cookie)
        opener = urllib.request.build_opener(handler)
        request = urllib.request.Request(url,postdata)
 
        try:
            response = opener.open(request)
        except urllib.error.URLError as e:
            print(e.code, ':', e.reason)
 
        # 保存cookie到cookie.txt中
        cookie.save(ignore_discard=True, ignore_expires=True)
 
        # 把字典存放到session_id里面
        session_id ={}
 
        for item in cookie:
            session_id[item.name]=item.value
 
        return session_id
