客户端需要做的就是在执行完TcpClient1.Sendln后,直接调用 TcpClient1.Receiveln即可。该方法会等待服务器传回的信息。当然如果希望超时断开的话,也可以调用WaitForData方法,判断在给定时间内是否有数据返回。 四、 常见问题 问题:为什么TcpClient的OnReceive事件不响应服务器传回的数据? 原因很简单,OnReceive事件是由Tcp...
TcpClient1.Sendln(''); end; HttpLen := 0; //循环读取所有返回的数据头信息 while true do begin Test := TcpClient1.Receiveln(); Memo1.Lines.Add(Test); if Test = '' then Break; if Pos('Content-Length: ', Test) > 0 then begin Delete(Test, 1, 16); HttpLen := StrToInt(Test);...
TcpClient1.Active := true; if TcpClient1.Connected then begin //发送HTTP1.1指令 TcpClient1.Sendln('GET / HTTP/1.1'); TcpClient1.Sendln('Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, application/x-shockwave-flash, application/vnd.ms-excel, application/msword, */*'); TcpC...
TCPClient的一个常见用例是构建客户端-服务器应用程序,其中客户端连接到服务器进行数据交换。使用TCPClient,你可以轻松实现HTTP、FTP或针对特定应用需求的自定义协议等通信协议。通过利用TCPClient,你可以为Delphi应用程序创建稳健高效的网络解决方案。 In addition to sending and receiving data, TCPClient also provides fea...
When i send a message from TCPClient to a TCPServer it will be handled using OnExecute event in the server . Now i want to handle the received messages in the Client but TCPClient doesn't have any event for this. So i have to make a thread to handle them manually. how can i ...
while (Length(Memo1.Text) < HttpLen - 2) or (TcpClient1.WaitForData(0) and (HttpLen = 0)) do begin Memo1.Lines.Add(TcpClient1.Receiveln(#$0D#$0A)); Application.ProcessMessages; Edit1.Text := Format('总长度:%d 已下载:%d ', [HttpLen, Length(Memo1.Text)]); ...
TcpClient1Connect(Sender: TObject); var s : string; begin memo1.Lines.Add('connected'); TcpClient1.Sendln('GET /'); s := TcpClient1.Receiveln; memo1.Lines.Add(S); end; end. EDIT here is a real world example with a RTSP server (youtube in this case) I used Indy IdTcpClient ...
32、T。在DATA命令后跟随要发送的数据,并用空格将命令字 DATA 和数据分隔开表单布局 建立一个项目组,添加一个客户程序项目和一个服务器项目。客户程序和服务器程序的表单布局如同 2 和图 3所示。客户程序表单上放置 了 TIdTCPClient 组件,服务器程序表单上放置了TIdTCPServer 组件。为防止客户程序“冻结” ,还在...
6。如果我们象TCPCLIENT那样作个procedure TcpServerReceive(Sender: TObject; Buf: PAnsiChar; var DataLen: Integer),你面写处理代码,然后TCPSERVER1.OnReceive:=TcpServerReceive; OnSend也如此类推,应该就可以了。 7。这个方法没有测试,但原理是这样的,只不过TCPSERVER的OnReceive,OnSend在设计时看不到而已,不...
