无法使用运行或 CMD 下载文件

所以当我运行这个脚本时

powershell (New-Object System.Net.WebClient).DownloadFile('https://www.somewebsite.com', 'Somefolder\Somefile.zip')

我收到错误

由于行业对网络的改变，您现在必须使用 TLS 来连接网站。

# Required for use with web SSL sites
[Net.ServicePointManager]::SecurityProtocol = [Net.ServicePointManager]::SecurityProtocol -bor [Net.SecurityProtocolType]::Tls12

查看具体信息：

如果您希望将它们全部包含在您的代码中，那么就是这样：

$AllProtocols = [System.Net.SecurityProtocolType]'Ssl3,Tls,Tls11,Tls12'
[System.Net.ServicePointManager]::SecurityProtocol = $AllProtocols
