c++ RCF-2200源码模拟 一个服务端多个客户端客户端做任务服务端下发任务时要求不给正在执行任务客户端下发任务客户端代码和服务端代码给出实现源码

以下是一个基于RCF-2.2.0.0的C++服务端和客户端的模拟实现代码：

服务端代码（server.cpp）：

#include <iostream>
#include <string>
#include <vector>
#include <thread>
#include <mutex>
#include <RCF/RCF.hpp>

using namespace std;
using namespace RCF;

mutex mutex_;

class Task
{
public:
    Task(const string& name) : name_(name) {}

    void execute()
    {
        cout << "Executing task: " << name_ << endl;
        // 模拟任务执行时间
        this_thread::sleep_for(chrono::seconds(5));
        cout << "Task " << name_ << " completed." << endl;
    }

private:
    string name_;
};

class TaskService
{
public:
    void addTask(const string& taskName)
    {
        lock_guard<mutex> lock(mutex_);
        tasks_.emplace_back(taskName);
    }

    Task* getTaskForClient()
    {
        lock_guard<mutex> lock(mutex_);
        for (auto& task : tasks_)
        {
            if (!taskInExecution(task))
            {
                tasks_.erase(remove(tasks_.begin(), tasks_.end(), task), tasks_.end());
                return &task;
            }
        }
        return nullptr;
    }

private:
    bool taskInExecution(const Task& task)
    {
        // 模拟任务是否正在执行
        // 这里可以根据实际情况进行判断
        return false;
    }

    vector<Task> tasks_;
};

class TaskServiceInterface
{
public:
    virtual ~TaskServiceInterface() {}

    virtual void addTask(const string& taskName) = 0;
    virtual Task* getTaskForClient() = 0;
};

class TaskServiceImplementation : public TaskServiceInterface
{
public:
    void addTask(const string& taskName) override
    {
        taskService_.addTask(taskName);
    }

    Task* getTaskForClient() override
    {
        return taskService_.getTaskForClient();
    }

private:
    TaskService taskService_;
};

class TaskServiceImplementationFacade
{
public:
    TaskServiceImplementationFacade()
    {
        RcfInitDeinit rcfInit;
        rcfServer_.bind<TaskServiceInterface>(taskServiceImplementation_);
    }

    void start()
    {
        rcfServer_.start();
    }

private:
    RcfServer rcfServer_;
    TaskServiceImplementation taskServiceImplementation_;
};

int main()
{
    TaskServiceImplementationFacade taskServiceFacade;
    taskServiceFacade.start();
    return 0;
}

客户端代码（client.cpp）：

#include <iostream>
#include <string>
#include <RCF/RCF.hpp>

using namespace std;
using namespace RCF;

class Task
{
public:
    Task(const string& name) : name_(name) {}

    void execute()
    {
        cout << "Executing task: " << name_ << endl;
        // 模拟任务执行时间
        this_thread::sleep_for(chrono::seconds(5));
        cout << "Task " << name_ << " completed." << endl;
    }

private:
    string name_;
};

int main()
{
    RcfInitDeinit rcfInit;

    RcfClient<TaskServiceInterface> taskServiceClient(RCF::TcpEndpoint("localhost", 50001));

    // 添加任务
    taskServiceClient.addTask("Task 1");
    taskServiceClient.addTask("Task 2");
    taskServiceClient.addTask("Task 3");

    // 获取任务并执行
    while (true)
    {
        Task* task = taskServiceClient.getTaskForClient();
        if (task)
        {
            task->execute();
        }
        else
        {
            cout << "No task available. Waiting for new tasks..." << endl;
            // 等待新任务
            this_thread::sleep_for(chrono::seconds(1));
        }
    }

    return 0;
}

请注意，上述代码仅为示例，实际应用中可能需要根据需求进行修改和扩展
