这是调试的时候，只要是调用本地的云函数就能成功

一旦调用远程的就报错，调用失败

本地node版本10.5.1；安装依赖库wx-server-sdk,crypto,qcloudsms_js

云开发环境

函数上传部署成功了的

云函数：代码如下

// 云函数入口文件

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

const QcloudSms = require("qcloudsms_js")

const crypto = require('crypto')

const sdkappid = "我的ID";

const appkey = "我的key";

const tpl_id = 442042;//短信模板ID

const smsSign = "签名";//短信签名

cloud.init()

// 云函数入口函数

exports.main = async (event, context) => new Promise((resolve, reject) => {

var qcloudsms = QcloudSms(sdkappid, appkey);

var ssender = qcloudsms.SmsSingleSender();

var phoneCode = () => {

let myCode = ' '；

for (let i = 0; i <= 3; i++) {

myCode += Math.floor(Math.random() * 10).toString();

}

return myCode

};//生成随机验证码

var param = new Array(phoneCode());//封装验证码

var hsparam = crypto.createHash('sha256').update(param[0]).digest('hex');

var nationcode = event.nationcode //手机号地区码

var userPhone = event.phone;//手机号码测试

ssender.sendWithParam(nationcode, userPhone, tpl_id, param, smsSign, "", "", (err, res, resData) => {

if (err) {

console.log("err: ", err);

reject({ err })

} else {

resolve({ res: res.req, resData, hsparam })

}

});

})
