- 当前 Bug 的表现（可附上截图）

- 预期表现

返回登录的session_key

- 复现路径

- 提供一个最简复现 Demo

小程序云端:

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

cloud.init({ env: 'wxcloudtest-399ef4' })

const axios = require('axios')

// 云函数入口函数

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

    const code = event.code

    const para = {

        appid: 'wx38369e8c688673ed',

        secret: '351193b1b3930ef1e89f7d1cf9ebfc83',

        js_code: code,

        grant_type: 'authorization_code'

    }

return new Promise((resolve, reject) => {

    axios.get(`https://api.weixin.qq.com/sns/jscode2session`, {

        params: para

    })

    .then(function (res) {

        resolve(res)

    })

    .catch(function (error) {

        return error

    })

})

}

小程序端：

wx.login({

    success(res) {

    if (res.code) {

        //发起网络请求

        console.log(res.code)

        wx.cloud.callFunction({

        name: 'sessionkey',

        data: { code: res.code },

        success: res => {

           console.log(res);

        },

        fail: err => {

            console.error('[云函数] [sessionkey] 调用失败', err)

        }

    })

    } else {

        console.log('err')

    }

    }

})
