这是调试的时候，只要是调用本地的云函数就能成功 [图片] 一旦调用远程的就报错，调用失败 [图片] [图片] 本地node版本10.5.1；安装依赖库wx-server-sdk,crypto,qcloudsms_js 云开发环境 [图片] 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 }) } }); })
