小程序要求的 TLS 版本必须大于等于 1.2

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

解决方法

执行powershell脚本
Powershell拥有自己的脚本，扩展名为“.ps1”.把下列内容复制保存成.ps1的后缀名，然后执行。

执行：开始->运行->cmd，在命令行下输入 PowerShell 进入 windows PowerShell

PS C:\PS> test.ps1

在 PowerShell中运行以下内容, 然后重启服务器

# Enables TLS 1.2 on windows Server 2008 R2 and Windows 7

# These keys do not exist so they need to be created prior to setting values.
md "HKLM:\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2"
md "HKLM:\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2\Server"

初次执行脚本时，可能会碰到一个异常：
File ” C:\PS\ test .ps1″ cannot be loaded because the
execution of scripts is disabled on this system. Please see
“get-help about_signing” for more details.
At line:1 char:10

这是powershell的默认安全设置禁用了执行脚本，要启用这个功能需要拥有管理员的权限。

开启：set-executionpolicy remotesigned

关闭：Set-ExecutionPolicy Restricted
