Question

我使用AutoIt创建了一个TCP客户端和-server。但是，当我发送welcome时，它从未收到过。我不确定为什么。代码是：

#include <Array.au3>
Global $Socket
Global $Recibe
Global $IP
Global $sDnsAddr = "address"
Global $PORT = 1234

$IP = TCPNameToIP($sDnsAddr)

While 1 ;Reconeccion
    _Conectar()
    TCPSend($Socket, "Hola")
    While 1 ; Recibir y ejecutar
        $Recibe = ""
        While $Recibe = ""
            $Recibe = TCPRecv($Socket, 10000000)
            Sleep(100)
        WEnd
        $Dat = StringSplit($Recibe, "|||")
        Select
            Case $Dat[1] = "Welcome"
                TCPSend("Hola que tal")
        EndSelect
    WEnd
WEnd

Func _Conectar()
    While TCPStartup() = 0
        Sleep(10)
    WEnd
    While True
        $Socket = TCPConnect($IP, $PORT)
        If $Socket > 0 Then
            Ejemplo()
            ExitLoop
        EndIf
        Sleep(1000)
    WEnd
EndFunc

我想发送消息并收到回复。像这样：

但结果是：

发送第一条TCP消息会导致我的脚本崩溃。我尝试使用127.0.0.1，但这也不起作用：

Answer 1

试试这个：

首先启动服务器：端口33891

将客户端或服务器编译为exe。然后首先启动Server，然后启动客户端，例如来自Scite4Autoit。

val optionMonoid1 = new Monoid[Option[A]] {
  def combine(a1: Option[A], a2: Option[A2]) a1 orElse a2
  def identity = None
}
