微信小程序  TLS 版本必须大于等于1.2问题解决

此问题最近在微信小程序开发中，比较常见。

在解决这个问题之前，我们需要了解一下，当前的系统环境是否支持TLS1.2以上，可以参考一下表格：

请先确认系统支持TLS1.2以后，进行一下操作：（如不支持请升级系统到支持版本）

windows2008R2在配置SSL做小程序开发时候提示小程序的TLS版本必须大于等于1.2。

解决方法：

请先备份导出HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols的值。如图：

将以下代码，保存到一个txt文件，然后修改后缀.reg，双击执行即可，完成这一步后，重启服务器。
