Of course, I tried the buttons in the unity window and pasting the command into PowerShell and running it
当然，窗口里的按钮和把指令粘贴到powershell并运行都试过

When I use http, the mode is actually websocket, but the stdio mode works fine, and I hope to fix this issue
我在使用http的时候其实模式是websocket，但是stdio模式就可以正常使用，我希望修复此问题
