Delphi服务端和PHP客户端通过Socket通信

标签：sys   服务   nis   alt   targe   click   操作   sage   tcp/ip   

在开始之前看下效果

PHP页面作为客户端发送请求给作为服务端的Delphi应用程序

PHP客户端页面打开如下

Delphi服务端应用程序打开如下

每次PHP页面刷新一下，Delphi的文本框都显示"我上线啦！"做的很粗糙，但是似乎可以作为某种功能的demo

PHP代码如下：

<?php

//
////确保在连接客户端时不会超时
//set_time_limit(0);
//
//$ip = ‘192.168.1.110‘;
//$port = 1025;
//

Delphi

设置：

ServerSocket1的Action为True;

ServerSocket1的Port为1025

代码 如下：

unit Unit1;


interface


uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, StdCtrls, ComCtrls, ScktComp;


type
  TForm1 = class(TForm)
    ServerSocket1: TServerSocket;
    StatusBar1: TStatusBar;
    Button1: TButton;
    Memo1: TMemo;
    Label4: TLabel;
    procedure ServerSocket1ClientConnect(Sender: TObject;
      Socket: TCustomWinSocket);
    procedure ServerSocket1ClientDisconnect(Sender: TObject;
      Socket: TCustomWinSocket);
    procedure ServerSocket1ClientRead(Sender: TObject;
      Socket: TCustomWinSocket);
    procedure Button1Click(Sender: TObject);


  private
    { Private declarations }
  public
    { Public declarations }
  end;


var
  Form1: TForm1;


implementation


{$R *.dfm}


procedure TForm1.ServerSocket1ClientConnect(Sender: TObject;
  Socket: TCustomWinSocket);
begin
StatusBar1.SimpleText := ‘connect‘;
end;


procedure TForm1.ServerSocket1ClientDisconnect(Sender: TObject;
  Socket: TCustomWinSocket);
begin
  StatusBar1.SimpleText := ‘disconnect‘;
end;


procedure TForm1.ServerSocket1ClientRead(Sender: TObject;
  Socket: TCustomWinSocket);
begin
 Memo1.Lines.Add(‘悄悄的对你说‘+ Socket.ReceiveText);
end;

end.
