标题: Qt TCP C/S通信源程序 tcp_Client与tcp_Server
TCP C/S 通信

源程序如下:

1. #include "widget.h"
   
2. #include "ui_widget.h"
   
3. 
   
4. Widget::Widget(QWidget *parent) :
   
5.     QWidget(parent),
   
6.     ui(new Ui::Widget)
   
7. {
   
8.     ui->setupUi(this);
   
9.     tcpSocket = new QTcpSocket;
   
10.     connect(tcpSocket,SIGNAL(connected()),this,SLOT(connect_success()));
    
11.     tcpSocket->connectToHost("10.0.2.15",8888);
    
12.     connect(tcpSocket,SIGNAL(readyRead()),this,SLOT(read_data()));
    
13. }
    
14. 
    
15. Widget::~Widget()
    
16. {
    
17.     delete ui;
    
18. }
    
19. 
    
20. void Widget::on_send_clicked()
    
21. {
    
22.     std::string msg = ui->msg->text().toStdString();
    
23.     tcpSocket->write(msg.c_str(),msg.size());
    
24.     ui->msg->clear();
    
25. }
    
26. 
    
27. void Widget::read_data()
    
28. {
    
29.     char buf[256] = {};
    
30.     tcpSocket->read(buf,sizeof(buf));
    
31.     ui->text->append(buf);
    
32. }
    
33. 
    
34. void Widget::connect_success()
    
35. {
    
36.     ui->send->setEnabled(true);
    
37. }
    
38. 
    
39. void Widget::on_msg_returnPressed()
    
40. {
    
41.     char msg[256] = {};
    
42.     sprintf(msg,"%s:%s",name,ui->msg->text().toStdString().c_str());
    
43.     tcpSocket->write(msg,strlen(msg));
    
44.     ui->msg->clear();
    
45. }
    
46. 
    
47. void Widget::on_name_returnPressed()
    
48. {
    
49.     sprintf(name,"%s",ui->name->text().toStdString().c_str());
    
50.     qDebug("%s",name);
    
51. }
