云函数中调用ocr.idcard总是返回参数错误 - WXOPEN Club

按照如下指导，使用云调用方式使用

// 云函数入口文件

const cloud = require('wx-server-sdk')

cloud.init()

// 云函数入口函数

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

const wxContext = cloud.getWXContext()

let imgUrl = 'https://...'

console.log(encodeURIComponent(imgUrl))

try {

const result = await cloud.openapi.ocr.idcard({

type: 'photo',

imgUrl: encodeURIComponent(imgUrl)

})

console.log(result)

return result

} catch (err) {

console.log(err)

return err

}

云端测试时总是报如下错误：

NOTE：此代码中的imgUrl是身份证照片，此处省略，测试时是有效的url。

使用https方式调用时是可以成功的，代码很简单，怀疑是个云端bug

如果不 encodeURIComponent？

@官方请看一下
