Golangexec.Command阻止在Windows上啟動服務的套接字/互聯網訪問？

我正在嘗試使用 exec.Command().Output() 來執行第 3 方工具 (SteamCMD) 來下載我運行的服務器的更新。當我通過 powershell 正常運行命令時，一切正常。

我運行的示例命令：

C:\SteamCMD\steamcmd.exe force_install_dir "C:\gameserver" login Mallachar app_update 233780

當我檢查應用程式的日志時，它作業正常。

但是，當我通過 Golang 運行它時，它不起作用

import (
    "fmt"
    "os/exec"
    "strings"
)

const armA3ServerID string = " app_update 233780"

func steamSession(configData Server, steamCMDUser string, steamCMDPass string) {
    var steamCMDCommand strings.Builder
    steamCMDCommand.WriteString(" force_install_dir \""   configData.Arma3path   "\" ")
    steamCMDCommand.WriteString(" login "   steamCMDUser   " "   steamCMDPass   " ")
    steamCMDCommand.WriteString(armA3ServerID)

    steamCMDCommand.WriteString("  quit")

    out, err := exec.Command(configData.Steamcmdpath "steamcmd.exe", steamCMDCommand.String()).Output()

    if err != nil {
        fmt.Printf("Error Is", err)
    }

    fmt.Printf("%s\n", string(out))
}

由于網路問題，命令掛起，我得到了這個日志輸出

When I terminate the background instance of the steamcmd running, my GoLang program prints out the output which showed it did tried to execute, but just hung at the connection part.

So As far as I can tell, it seems like when I used exec.Command, the services I launch with it do not have internet/socket access? I tried running as admin, but didn't seem to fix anything. Not sure if maybe there is a step I am missing or something I need to change flag wise.

So the command does run, the backend application runs, but it fails to resolve the address/make a connection. So seems like my command itself is not the issue, but something with GoLang exec.Command?

uj5u.com熱心網友回復：

您正在向命令傳遞一個引數，即所有引數的串聯。試試這個：

   out, err := exec.Command(
     configData.Steamcmdpath "steamcmd.exe",
     " force_install_dir", configData.Arma3path,
     " login ",steamCMDUser,steamCMDPass,
      " app_update", "233780",
     " quit",
  ).Output()
