vb和php 基于socket通信

Posted 2020-07-11 两只小蜜蜂啊

php代码（页面代码非cmd命令脚本）

 

<?php

$server = \'127.0.0.1\';
$port = 8888;

$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
if($socket < 0) {
    echo socket_strerror($socket);
} else {
    echo \'成功<br />\';
}


$result = @socket_connect($socket, $server, $port);

$buf = $_GET[\'message\'];


$len = strlen($buf);

socket_send($socket, $buf, $len, 0);

socket_close($socket);

?>

vb代码

Option Explicit


Private Sub Form_Load()
    tcpServer.LocalPort = 8888
    tcpServer.Listen
    lblstate.Caption = "目前没有客户端连入！"
End Sub

Private Sub tcpServer_ConnectionRequest(ByVal requestID As Long)
    If tcpServer.State <> sckClosed Then tcpServer.Close
    tcpServer.Accept requestID
    lblstate.Caption = "有客户端连入本机！ IP：" & tcpServer.RemoteHostIP
End Sub

Private Sub tcpServer_DataArrival(ByVal bytesTotal As Long)
    Dim strData As String
    tcpServer.GetData strData
    txtOutput.Text = strData & vbCrLf & txtOutput.Text
    tcpServer.Close
    tcpServer.Listen
End Sub


Private Sub txtSendData_KeyPress(KeyAscii As Integer)
    If KeyAscii = 13 Then
        If tcpServer.State = sckConnected Then
            tcpServer.SendData "服务器说：" & txtSendData.Text
            txtOutput.Text = "服务器说" & txtSendData.Text & vbCrLf & txtOutput.Text
            txtSendData.Text = ""
        Else
            MsgBox "目前没有连接的客户端！"
        End If
    End If
End Sub

效果
