simple websocket用法

项目地址在：https://gitlab.com/eidheim/Simple-Web-Server

我调试通过的代码如下：

cpp 复制代码

#include "server_ws.hpp"

using namespace std;

using WsServer = SimpleWeb::SocketServer<SimpleWeb::WS>;

void run_simple_socket_server(unsigned short port)
{
    WsServer server;
    server.config.port = port;

    auto &echo = server.endpoint["^/echo/?$"];
    echo.on_message = [](shared_ptr<WsServer::Connection> connection, shared_ptr<WsServer::Message> message)
    {
        auto message_str = message->string();

        cout << "Server: Message received: \"" << message_str << "\" from " << connection.get() << endl;

        cout << "Server: Sending message \"" << message_str << "\" to " << connection.get() << endl;

        auto send_stream = make_shared<WsServer::SendStream>();
        *send_stream << message_str;
        connection->send(send_stream, [](const SimpleWeb::error_code &ec)
                         {
                    if (ec) {
                        cout << "Server: Error sending message. " <<
                            "Error: " << ec << ", error message: " << ec.message() << endl;
                    } });
    };

    echo.on_open = [](shared_ptr<WsServer::Connection> connection)
    {
        cout << "Server: Opened connection " << connection.get() << endl;
    };

    echo.on_close = [](shared_ptr<WsServer::Connection> connection, int status, const string & /*reason*/)
    {
        cout << "Server: Closed connection " << connection.get() << " with status code " << status << endl;
    };

    echo.on_error = [](shared_ptr<WsServer::Connection> connection, const SimpleWeb::error_code &ec)
    {
        cout << "Server: Error in connection " << connection.get() << ". "
             << "Error: " << ec << ", error message: " << ec.message() << endl;
    };

    thread server_thread([&server]()
                         { server.start(); });
    server_thread.join();
}
int main(int argc, char const *argv[])
{
    unsigned short port = 10088;
    cout << "Server port: " << port << endl;
    run_simple_socket_server(port);
    return 0;
}

Makefile如下：

bash 复制代码
