您还可以查看 QtWebSockets。 QtWebSockets 可用于客户端和服务器应用程序，并通过了 Autobahn 测试套件。

You can also have a look at QtWebSockets. QtWebSockets can be used both for client and server applications, and passes the Autobahn test suite.

QtWebKit 内部的 QWebView 支持使用 Web Sockets（来自 HTML5 标准）。我已经使用它们多次，没有任何问题。

QWebView inside of QtWebKit supports the use of Web Sockets (from the HTML5 standard). I have used them multiple times without any issue.

我创建了一个例子。以下是代码：

inspection_server.hpp:

#ifndef __INSPECTION_SERVER_HPP__
#define __INSPECTION_SERVER_HPP__

#include <QWebSocketServer>
#include <QWebSocket>
#include <QObject>
#include <iostream>
#include <memory>

class InspectionServer;

typedef std::shared_ptr<QWebSocketServer> QWebSocketServerPtr;
typedef std::shared_ptr<QWebSocket> QWebSocketPtr;
typedef std::shared_ptr<InspectionServer> InspectionServerPtr;

class InspectionServer: public QObject
{
    Q_OBJECT

    QWebSocketServerPtr websocketServer;
    QList<QWebSocketPtr> clients;

public:
    InspectionServer(uint16_t port);

signals:
    void closed();

private slots:
    void onNewConnection();
    void processTextMessage(const QString& message);
    void socketDisconnected();

};

#endif

inspection_server.cpp:

#include "inspection_server.hpp"

#include <QDebug>

InspectionServer::InspectionServer(uint16_t port)
    : websocketServer(new QWebSocketServer(QStringLiteral("Inspection server"), QWebSocketServer::NonSecureMode))
{
    if(this->websocketServer->listen(QHostAddress::Any, port))
    {
        QObject::connect(websocketServer.get(), SIGNAL(newConnection()), this, SLOT(onNewConnection()));
    }
    else
    {
        throw std::runtime_error("InspectionServer: failed to listen");
    }
}

void InspectionServer::onNewConnection()
{
    qInfo() << "InspectionServer::onNewConnection";
    QWebSocketPtr socket(this->websocketServer->nextPendingConnection());

    QObject::connect(socket.get(), SIGNAL(textMessageReceived(const QString&)), this, SLOT(processTextMessage(const QString&)));
    QObject::connect(socket.get(), SIGNAL(disconnected()), this, SLOT(socketDisconnected()));

    this->clients.append(socket);
}

void InspectionServer::processTextMessage(const QString& message)
{
    qInfo() << "InspectionServer::processTextMessage: " << message;
}

void InspectionServer::socketDisconnected()
{
    qInfo() << "InspectionServer::socketDisconnected";
}

main.cpp:

#include "inspection_server.hpp"

#include <QCoreApplication>

int main(int argc, char** argv)
{
    QCoreApplication app(argc, argv);

    InspectionServer server(1234);

    return app.exec();
}

以下是如何在 Web 浏览器中测试该代码：

<html>
<body>
<button onClick="initWebSocket();">Connect</button>
<br>
<input type="text" id="messageInput">
<button onClick="sendMessage();">Send message</button>
</body>
</html>

<script type="text/javascript">

var websocket = null;

function initWebSocket()
{
    websocket = new WebSocket("ws://localhost:1234");
}

function sendMessage()
{
    websocket.send(document.getElementById("messageInput").value);
}

</script>

I have created an example. Here is the code:

inspection_server.hpp:

#ifndef __INSPECTION_SERVER_HPP__
#define __INSPECTION_SERVER_HPP__

#include <QWebSocketServer>
#include <QWebSocket>
#include <QObject>
#include <iostream>
#include <memory>

class InspectionServer;

typedef std::shared_ptr<QWebSocketServer> QWebSocketServerPtr;
typedef std::shared_ptr<QWebSocket> QWebSocketPtr;
typedef std::shared_ptr<InspectionServer> InspectionServerPtr;

class InspectionServer: public QObject
{
    Q_OBJECT

    QWebSocketServerPtr websocketServer;
    QList<QWebSocketPtr> clients;

public:
    InspectionServer(uint16_t port);

signals:
    void closed();

private slots:
    void onNewConnection();
    void processTextMessage(const QString& message);
    void socketDisconnected();

};

#endif

inspection_server.cpp:

#include "inspection_server.hpp"

#include <QDebug>

InspectionServer::InspectionServer(uint16_t port)
    : websocketServer(new QWebSocketServer(QStringLiteral("Inspection server"), QWebSocketServer::NonSecureMode))
{
    if(this->websocketServer->listen(QHostAddress::Any, port))
    {
        QObject::connect(websocketServer.get(), SIGNAL(newConnection()), this, SLOT(onNewConnection()));
    }
    else
    {
        throw std::runtime_error("InspectionServer: failed to listen");
    }
}

void InspectionServer::onNewConnection()
{
    qInfo() << "InspectionServer::onNewConnection";
    QWebSocketPtr socket(this->websocketServer->nextPendingConnection());

    QObject::connect(socket.get(), SIGNAL(textMessageReceived(const QString&)), this, SLOT(processTextMessage(const QString&)));
    QObject::connect(socket.get(), SIGNAL(disconnected()), this, SLOT(socketDisconnected()));

    this->clients.append(socket);
}

void InspectionServer::processTextMessage(const QString& message)
{
    qInfo() << "InspectionServer::processTextMessage: " << message;
}

void InspectionServer::socketDisconnected()
{
    qInfo() << "InspectionServer::socketDisconnected";
}

main.cpp:

#include "inspection_server.hpp"

#include <QCoreApplication>

int main(int argc, char** argv)
{
    QCoreApplication app(argc, argv);

    InspectionServer server(1234);

    return app.exec();
}

And here is how to test that in your Web browser:

<html>
<body>
<button onClick="initWebSocket();">Connect</button>
<br>
<input type="text" id="messageInput">
<button onClick="sendMessage();">Send message</button>
</body>
</html>

<script type="text/javascript">

var websocket = null;

function initWebSocket()
{
    websocket = new WebSocket("ws://localhost:1234");
}

function sendMessage()
{
    websocket.send(document.getElementById("messageInput").value);
}

</script>
