从SSH会话Golang读取数据

启动会话的单个阅读器goroutine。该goroutine从会话中读取数据并将数据发送到通道。

在主goroutine中，循环选择接收数据和超时情况。适当处理每种情况。

type SSHLib struct {    Stdout io.Reader    Buffer string    Data   chan string  // <-- Add this member}// New creates a new SSHLib. This example shows the pre // relevant to reading stdout only. func New() *SSHLib {    s := &SSHLib{data: make(chan string)}    go s.Reader()    return s}// Reader reads data from stdout in a loop.func (s *SSHLib) Reader() {    var data = make([]byte, 1024)    for {        n, err := s.Stdout.Read(data)        if err != nil { // Handle error return        }        s.Data <- string(data[:n])    }}// GetData receives data until regexp match or timeout.func (s *SSHLib) GetData() {    t := time.NewTimer(time.Second)    defer t.Stop()    for {        select {        case d := <-s.data: s.Buffer += d // Check for regexp match in S.Buffer        case <-t.C: // Handle timeout return        }    }}
