步骤：先使用appid&secret获取access_token->再使用access_token获取ticket->获取时间戳->创建随机字符串—>将前面的后3个以及传值过来的实时url根据字符的ASCII值进行排序，拼接 ->最后对拼接的字符串作sha1加密，字段名和字段值都采用原始值，不进行URL 转义对字符串作sha1加密，字段名和字段值都采用原始值，不进行URL 转义参考链接：https://mp.weixin.qq.com/wiki?t=resource/res_main&id=mp1421141115#!/usr/bin/python3# -*- coding: utf-8 -*-# @File    : share# @Author  : moucong# @Date    : 2019/2/17 14:35# @Software: PyCharmimport hashlibimport stringimport urllib.requestimport jsonimport timeimport random

备注小笔记：我使用的是Django进行后端部署和传值，之后使用ajax进行前端获取和传url回到后端，后来遇到跨域问题，使用nginx转发端口解决了，获取ticket和token使用while true,time.sleep(7200)解决，存为json.
