結論

[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls -bor [Net.SecurityProtocolType]::Tls11 -bor [Net.SecurityProtocolType]::Tls12
Invoke-RestMethod -uri "https://test.azurewebsites.net/?a=1&b=2"

問題

1. 如果 uri 有 & 則需要使用雙引號包起來
2. 放上去執行出現錯誤：PowerShell – 
   The underlying connection was closed: An unexpected error occurred on a send.
   需要加上第一行來使 PS 使用 TLS 1.2

參照

The underlying connection was closed: An unexpected error occurred on a send
