#插件讨论# 【 uni-cloud-s2s公共模块 - DCloud前端团队 】示例使用都有问题，请给出详细教程

直接使用示例代码都报错，能不能给个详细的使用教程

官方文档示例代码

const {
verifyHttpInfo
} = require('uni-cloud-s2s')

exports.main = async (event) => {
verifyHttpInfo({
httpMethod: 'POST',
headers: {
'content-type': 'application/x-www-form-urlencoded',
'Unicloud-S2s-Timestamp': '1677090154735',
"Unicloud-S2s-Signature": "hmac-sha256 74416c6ffaa74bc3b70a1dca7c66406dd113e2f0aaf9713d7c3bd19a21d77b47"
},
body: 'a=1&b=2&c=3'
})
};

错误信息

Invalid uni-cloud-s2s config, expected policy is "code" or "sign", got undefined

补充

1、按官方示例const { verifyHttpInfo} = require('uni-cloud-s2s') 引入s2s模块是不行的，还需要在引入该模块的云函数管理公共依赖中引入s2s。
2、于应用市场引入s2s后，仅有index.js、package.json文件，不含官方文档描述中config.json文件，自己创建后复制官方文档中代码 并删掉注释，上传公共模块及云函数后运行报上述错误信息
