先获取access_token
https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=你的appid&secret=你的密钥
使用raw方式,测试用postman
body填json:
(scene)是参数
{
“path”: “pages/index/index”,
“scene”: “”
}
POST请求:
- url (access_token)替换自己的

#####这只是其中的一种请求获取的方式,更多的方式查看
小程序获取二维码
#上面的是通过postman来获取小程序码,下面的是通过代码获取
