我很少在 Stack Overflow 上提问，但这次我却陷入了困境。

TLDR我需要知道它channel.Close()是如何golang.org/x/crypto/ssh工作的以及我应该在哪里调用它（假设这是我需要的）。

我正在编写一个“小”程序来自动同步我的 Git 存储库，包括存储、额外文件等。我使用go-ssh来处理服务器上最重要的部分。该项目的当前状态可以在 GitHub 上找到

我试图将其缩小到一个简单的示例。这是我从Golang 存储库中的官方示例中调整的少数内容之一。我删除了terminal引用，并使其明确处理（随机）命令：

go func(in <-chan *ssh.Request) {
    for req := range in {
        switch req.Type {
        case "exec":
            channel.Stderr().Write([]byte("Request received!\n"))
            req.Reply(true, nil)
            // Do some more work here
            channel.Close() // ???
        default:
            req.Reply(false, nil)
        }
    }
    wg.Done()
}(requests)

要点在这里。这里还有另一个来自其他人的例子。

每当我尝试连接类似ssh localhost -T -vvvv -p 2022 git-receive-pack foo示例的内容时，我都会得到以下信息：

在我的个人项目中，也会出现“破管”的情况。

有谁知道如何解决这个问题？
