Laila's questions

我正在尝试使用uwebsocket库创建服务器/客户端的最小示例。

在我下面的尝试中，服务器正在启动，它输出“服务器正在监听端口 9001”，但是客户端没有连接，客户端上没有任何 lambda 正在命中。

我还想知道当服务器重启时如何重新连接客户端。

#include <uwebsockets/App.h>
#include <thread>
#include <iostream>

class Server
{
public:
    bool connected = false;
    void runServer()
    {
        uWS::App().ws<Server>("/*", 
        {
            .open = [this](auto* ws) 
            {
                ws->subscribe("broadcast");
                std::cout << "Server: Client connected" << std::endl;
            },
            .message = [](auto* ws, std::string_view message, uWS::OpCode opCode)
            {
                ws->publish("broadcast", message, opCode);
                std::cout << "Server: Received and broadcast message: " << message << std::endl;
            },
            .close = [](auto* ws, int code, std::string_view message)
            {
                std::cout << "Server: Client disconnected" << std::endl;
            }
        }).listen(9001, [this](auto* listen_socket)
        {
            if (listen_socket) 
            {
                std::cout << "Server listening on port 9001" << std::endl;
                connected = true;
            }
        }).run();
    }
};

class Client
{
public:
    void runClient() 
    {
        uWS::App().ws<Client>("/*",  uWS::App::WebSocketBehavior<Client>
        {
            .open = [this](auto* ws) 
            {
                std::cout << "Client: Connected to server" << std::endl;
                ws->send("Hello from client!", uWS::OpCode::TEXT);
            },
            .message = [](auto* ws, std::string_view message, uWS::OpCode opCode)
            {
                std::cout << "Client: Received message: " << message << std::endl;
            },
            .close = [](auto* ws, int code, std::string_view message)
            {
                std::cout << "Client: Disconnected from server" << std::endl;
            }
        }).connect("ws://localhost:9001", nullptr).run();
    }
};



int main()
{
    Server server;
    std::thread server_thread([&server]() { server.runServer(); });

    while (!server.connected)
    {
        std::this_thread::sleep_for(std::chrono::milliseconds(100));
    }

    Client client;
    client.runClient();

    server_thread.join();
    return 0;
}

我正在尝试创建一个过滤器来仅比较.cpp和.h文件，但它不应该比较名称为的文件夹.vshistory。

这是我得到的：

## This is a directory/file filter template for WinMerge
name: C++ Files
desc: Filter for C++ source and header files

## This is an exclusive filter
## (it lets through only matching files)
def: exclude

f: \.(cpp|h)$  ## To compare only .cpp and .h files
d: \\(?<!\.vshistory)

它只比较.cpp文件.h但没有忽略.vshistory文件夹，这有什么问题？
