我的 GO 版本是 1.1.1
服务器在连接关闭后收到消息,但设置了 NoDelay。
有什么不对
addr, _ := net.ResolveTCPAddr("tcp", "localhost:5432")
conn, err := net.DialTCP("tcp", nil, addr)
defer conn.Close()
if err != nil {
fmt.Println("connect fail")
return
}
err = conn.SetNoDelay(true)
if err != nil {
fmt.Println(err.Error())
}
for {
var message string
_, err := fmt.Scanln(&message)
if err != nil && err.Error() != "unexpected newline" {
fmt.Println("input finished", err)
break
}
if message == "" {
fmt.Println("no input, end")
break
}
// message = fmt.Sprintf("%s\n",message)
//fmt.Fprintf(conn, message) // send immediately but following message won't send any more
conn.Write([]byte(message)) // won't send until connection close
}
