QT实现TCP通信(客户端和服务器同时包含在一个cpp文件中)
以下是一个用QT5写的电脑录音并通过TCP客户端发送到服务器的示例代码,包括.pro、.h和.cpp文件。
.pro文件:
```
QT += network
TARGET = RecorderClient
CONFIG += c++11 console
SOURCES += main.cpp recorder.cpp
HEADERS += recorder.h
```
.recorder.h文件:
```cpp
#ifndef RECORDER_H
#define RECORDER_H
#include <QObject>
#include <QTcpSocket>
#include <QAudioInput>
class Recorder : public QObject
{
Q_OBJECT
public:
explicit Recorder(QObject *parent = nullptr);
signals:
public slots:
void startRecording();
void stopRecording();
private slots:
void sendData();
private:
QTcpSocket *m_tcpSocket;
QAudioInput *m_audioInput;
QByteArray m_buffer;
bool m_isRecording;
};
#endif // RECORDER_H
```
.recorder.cpp文件:
```cpp
#include "recorder.h"
#include <QDebug>
#include <QHostAddress>
Recorder::Recorder(QObject *parent) : QObject(parent)
{
m_isRecording = false;
m_tcpSocket = new QTcpSocket(this);
}
void Recorder::startRecording()
{
if (m_isRecording) {
qDebug() << "Already recording.";
return;
}
m_isRecording = true;
QAudioFormat format;
format.setSampleRate(44100);
format.setChannelCount(2);
format.setSampleSize(16);
format.setCodec("audio/pcm");
format.setByteOrder(QAudioFormat::LittleEndian);
format.setSampleType(QAudioFormat::SignedInt);
QAudioDeviceInfo info(QAudioDeviceInfo::defaultInputDevice());
if (!info.isFormatSupported(format)) {
qDebug() << "Format not supported.";
return;
}
m_audioInput = new QAudioInput(format, this);
m_audioInput->start(m_tcpSocket);
connect(m_tcpSocket, SIGNAL(connected()), this, SLOT(sendData()));
}
void Recorder::stopRecording()
{
if (!m_isRecording) {
qDebug() << "Not recording.";
return;
}
m_audioInput->stop();
m_audioInput->deleteLater();
m_audioInput = nullptr;
m_isRecording = false;
}
void Recorder::sendData()
{
m_buffer.resize(m_audioInput->bytesReady());
m_audioInput->read(m_buffer.data(), m_buffer.size());
m_tcpSocket->write(m_buffer);
}
```
main.cpp文件:
```cpp
#include <QCoreApplication>
#include "recorder.h"
int main(int argc, char *argv[])
{
QCoreApplication a(argc, argv);
Recorder recorder;
recorder.startRecording();
return a.exec();
}
```
这个示例代码使用Qt Network模块与服务器建立TCP连接,并使用Qt Multimedia模块进行录音。在录音期间,数据将被实时发送到服务器。您需要自行实现服务器端来接收和保存此数据。
