1、云函数 name

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

wx.cloud.init({

env: "xxxxxx"

})

const db = cloud.database()

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

try {

return await db.collection('gxser').doc('a85ed387c100134853').get()

}

catch (err) {

console.log(err)

}

}

2、pages中的index.js

Page({

onAdd:function() {

wx.cloud.callFunction({

name: "name",

success(res) {

console.log("请求成功", res)

},

fail(res) {

console.log("请求失败", res)

}

})

}

})

3、index.wxml

<button bindtap="onAdd">用函数</button>

--------------------------------------------------------------------------------------------

运行提示：

请求失败 Error: errCode: -404011 cloud function execution error | errMsg: cloud.callFunction:fail requestID b5007aac-a98c-11ea-922e-5254001dad8e, cloud function service error code -504002, error message wx is not defined; at cloud.callFunction api;
