前端发送code到后端

    wx.login({

      success: (res) => {

        const usercode=res.code

        myrequest({url:'/getopenid',data: {usercode:usercode},method: 'POST'}).then(res1=>{

            console.log(res1)

        })

后端正常接收

[Object: null prototype] {

  usercode: '0e3p9p1w3uYLA03L3k4w3wiXaF3p9p1J'

}

后端代码

exports.getopenid=async (req,res)=>{

    const code=req.body

    console.log(code)

    var params = {

        grant_type:'authorization_code',

        appid: '正确在详情里复制',

        //secret 更新时间20230504

        secret: '已经于20230504重置并更新',

        js_code:code

    }

    params=JSON.stringify(params)

    axios({

        method:'GET',

        url:'https://api.weixin.qq.com/sns/jscode2session'+params

    }).then(res2=>{

        res.send(res2.data)

    })

}
