云函数部分

// 云函数入口函数

exports.main = async (event, context) => {

    try {

      const result = await cloud.openapi.wxacode.getUnlimited({

          "path": 'pages/square/userInfo/userInfo?id='+event.openId,

          "width": 280,

          "isHyaline":true,

          "scene": 'oskUN5hwrBJ7EqZSIwUEI6EkWNlA',

          "checkPath": false, //设置不透明底色

          "envVersion": 'release'

        })

      return result

    } catch (err) {

      return err

    }

  }

参数哪不对呢？
