移植二维码实现登录功能

简单粗暴

上代码

import re
import time
import requests
import json

CURRENT_TIME = None

LOGIN_COOKIE_DICT = {}
TICKET_COOKIE_DICT = {}
TIPS = 1


def log(request):
    base_qcode_url = 'https://login.wx.qq.com/jslogin?appid=wx782c26e4c19acffb&redirect_uri=https%3A%2F%2Fwx.qq.com%2Fcgi-bin%2Fmmwebwx-bin%2Fwebwxnewloginpage&fun=new&lang=zh_CN&_={0}'
    global CURRENT_TIME
    CURRENT_TIME = str(time.time())
    q_code_url = base_qcode_url.format(CURRENT_TIME)
    response = requests.get(q_code_url)
    print(response.text)
    # code代表二维码后缀
    code = re.findall('uuid = "(.*)";', response.text)[0]
    global QCODE
    QCODE = code
    return render(request, "log.html", {'code': code})


def long_polling(request):
    ret = {'status': 408, 'data': None}
    try:
        global TIPS
        base_login_url = 'https://login.wx.qq.com/cgi-bin/mmwebwx-bin/login?loginicon=true&uuid={0}&tip={1}&r=-1359574064&_={2}'
        login_url = base_login_url.format(QCODE, TIPS, CURRENT_TIME)
        response_login = requests.get(login_url)
        if "window.code=201" in response_login.text:
            TIPS = 0
            avatar = re.findall("userAvatar = '(.*)';", response_login.text)[0]
            ret['data'] = avatar
            ret['status'] = 201
        elif "window.code=200" in response_login.text:
            LOGIN_COOKIE_DICT.update(response_login.cookies.get_dict())
            redirect_uri = re.findall('redirect_uri="(.*)";', response_login.text)[0]
            redirect_uri += '&fun=new&version=v2&lang=ch_CN'

            # from bs4 import BeautifulSoup
            # print(ret.text)
            ret['status'] = 200
            print(response_login.text)
    except Exception as e:
        print(e)
      
    return HttpResponse(json.dumps(ret))

前端代码

    $(function () {

        });
    function polling() {

        {#console.log(1);#}
        {#polling();#}
        $.ajax({
            url:'/polling/',
            type:'GET',
            dataType:'json',
            success: function (arg) {
                if (arg.status==408) {
                    polling();
                }else if (arg.status==201) {
                   // 获取图片接着发
                    $('#qcode').attr('src',arg.data);  //将获得的图片地址赋值给data
                    polling();
                }else {
                    location.href='/inde/'
                }


            }

        })
    }
</script>
</body>
</html>

看就完事了
