微信公众号开发者平台提供短网址生成的API，最终生成的短网址是的，下面是详细的代码。
官方文档
https://developers./doc/offiaccount/Account_Management/URL_Shortener.html
请求参数
access_token
action此处填long2short，代表长链接转短链接
long_url需要转换的原链接
HTTP POST请求网址
https://api./cgi-bin/shorturl?access_token=ACCESS_TOKEN
请求流程
1、获取本地缓存的access_token，如果超过有效期，则重新获取，如果还没过期，直接使用缓存的access_token
2、构建请求参数，发起POST请求
3、获得短网址
代码
appid和appsecret可以申请一个微信公众号测试账号进行开发，申请地址：http://mp./debug...

生成示例
{"result":"100","msg":"生成成功","dwz":"https:\/\/\/s\/AF5p0UM"}
