1、打开IIS → 服务器证书 → 创建自签名证书
2、网站 → 绑定 → 添加绑定 → https → 在ssl中选择刚创建的证书
3、cmd测试：curl -k https://127.0.0.1/home
如果报错SEC_E_WRONG_PRINCIPAL (0x80090322) - 目标主要名称不正确
说明证书不被认可，跳过证书检查，需要加上-k
4、测试：curl -k -v https://127.0.0.1/home
加上 -v 可以查看运行的详细过程 ，详细信息如下
* Trying 127.0.0.1:443...

4、如果强制要求https，则 网站 → SSL设置 → 要求SSL证书 → 应用
如果程序添加app.UseHttpsRedirection(); 则会自动转发成https。
5、微信小程序不承认自己颁发的证书，可以去阿里云免费申请一年的SSL
