node.js - 如何用express设置微信小程序的本地后台服务器？

问题描述

微信小程序的官方文档上写：发起的是https请求，且不能带端口

1.如何让express不监听端口直接就能链接？2.微信小程序建立的链接一定是要https吗？https要怎么弄？

问题解答

1、nginx监听本地express的端口3000；2、阿里云可以申请免费的https证书

已经贴出的我conf配置文件，可以参考，监听3000端口以及配制证书都在这个文件里修改

下边是阿里云申请免费证书的地址https://common-buy.aliyun.com...

阿里云也有配置HTTPS的具体示例
