小程序报错：对应的服务器 TLS 为 TLS 1.0 ，小程序要求的 TLS 版本必须大于等于 1.2

我这里出现此错误的原因是，搭载域名网站的服务器是windows2008 r2，配置的域名证书是TLS1.0版本，需要在服务器注册表中加入TLS的其他版本。

服务器是windows 2008 server 
环境是IIS7
SSL是申请用的阿里免费。微信小程序发现wx.request,调试报错: 小程序要求的 TLS 版本必须大于等于 1.2

直接说解决办法吧：在PowerShell中运行一下代码(复制粘贴即可),PowerShell窗口打开方式可以用下面任意一种
1：开始->运行->输入 PowerShell

2：开始->所有程序->附件 找到

输入以上命令后直接回车
3：重启服务器(我滴重启iis好像没彻底生效)后OK，再请请求wx.request正常
