基本逻辑

功能实现流程

  • 服务注册和发现
    • 通过服务注册模块将服务注册到服务中心
    • 通过服务发现模块进行服务发现，管理可用的用户子服务
  • 消息传递流程
    • 客户端通过调用RPC方法，传递请求消息
    • 服务根据请求获取用户信息、构建消息对象、查询聊天会话成员
    • 消息通过消息队列（RabbitMQ）进行持久化，确保消息的可靠传递
  • RPC服务
    • 通过实现RPC接口，处理客户端请求并返回结果
  • 消息队列 
    • 消息发布到消息队列中，其他服务可以对该队列中的消息进一步处理

具体实现

 数据管理

ODB

#pragma once
#include <string>
#include <cstddef> 
#include <odb/core.hxx>

namespace mag {
#pragma db object table("chat_session_member")
class ChatSessionMember {
    public:
        ChatSessionMember(){}
        ChatSessionMember(const std::string &ssid, const std::string &uid):
            _session_id(ssid), _user_id(uid){}
            ~ChatSessionMember(){}

        std::string session_id() const { return _session_id; }
        void session_id(std::string &ssid)  { _session_id = ssid; }
        
        std::string user_id() const { return _user_id; }
        void user_id(std::string &uid)  { _user_id = uid; }
    private:
        friend class odb::access;
        #pragma db id auto
        unsigned long _id;
        #pragma db type("varchar(64)") index 
        std::string _session_id;
        #pragma db type("varchar(64)") 
        std::string _user_id;
};
}

 mysql数据库操作，针对于聊天会话成员表

  • 新增单个会话成员
  • 新增多个会话成员
  • 删除单个会话成员
  • 删除多个会话成员
  • 获取会话成员
#pragma once
#include "mysql.hpp"
#include "chat_session_member.hxx"
#include "chat_session_member-odb.hxx"

namespace mag

                trans.commit();

    private:
        std::shared_ptr<odb::core::database> _db; 

    };
}

业务逻辑实现

  • 获取请求信息：从请求中提取关键信息（请求ID、用户ID、聊天会话ID等）
  • 用户服务调用：通过RPC调用获取目标用户信息
  • 消息构建：构建消息对象并从数据库获取目标用户
  • 消息发布：将消息发布到消息队列以便传递给目标用户
  • 响应构造：构造响应，包括消息和目标用户信息，并返回给客户端

其他搭建RPC与前面业务逻辑类似

void GetTransmitTarget(google::protobuf::RpcController* controller,
                       const ::mag::NewMessageReq* request,
                       ::mag::GetTransmitTargetRsp* response,
                       ::google::protobuf::Closure* done) override{
                        //RPC调用后释放资源    
                        brpc::ClosureGuard rpc_guard(done);
                        //错误处理
                        auto err_response = [this, response](const std::string &rid, const std::string &errmsg) -> void {
                        response->set_request_id(rid);
                        response->set_success(false);
                        response->set_errmsg(errmsg);
                        return;
                    };

                    //请求中获取信息
                    std::string rid = request->request_id();
                    std::string uid = request->user_id();
                    std::string chat_ssid = request->chat_session_id();
                    const MessageContent &content = request->message();

                    //选择服务通道
                    auto channel = _mm_channels->choose(_user_service_name);
                    if (!channel) {
                        LOG_ERROR("{}-{} 没有可供访问的用户子服务节点！", rid, _user_service_name);
                        return err_response(rid, "没有可供访问的用户子服务节点！");
                    }                       

                    //RPC调用用户子服务获取用户信息
                    UserService_Stub stub(channel.get());
                    GetUserInfoReq req;
                    GetUserInfoRsp rsp;
                    req.set_request_id(rid);
                    req.set_user_id(uid);
                    brpc::Controller cntl;
                    stub.GetUserInfo(&cntl, &req, &rsp, nullptr);
                    if (cntl.Failed() == true || rsp.success() == false) {
                        LOG_ERROR("{} - 用户子服务调用失败：{}！", request->request_id(), cntl.ErrorText());
                        return err_response(request->request_id(), "用户子服务调用失败!");
                    }

                    //构建消息对象
                    MessageInfo message;
                    message.set_message_id(uuid());
                    message.set_chat_session_id(chat_ssid);
                    message.set_timestamp(time(nullptr));
                    message.mutable_sender()->CopyFrom(rsp.user_info());
                    message.mutable_message()->CopyFrom(content);

                    //获取消息转发的目标用户列表，从mysql数据库中获取
                    auto target_list = _mysql_session_member_table->members(chat_ssid);

                    //发布消息到消息队列
                    bool ret = _mq_client->publish(_exchange_name, message.SerializeAsString(), _routing_key);
                    if (ret == false) {
                        LOG_ERROR("{} - 持久化消息发布失败：{}！", request->request_id(), cntl.ErrorText());
                        return err_response(request->request_id(), "持久化消息发布失败：!");
                    }

                    //组织成功响应
                    response->set_request_id(rid);
                    response->set_success(true);
                    response->mutable_message()->CopyFrom(message);
                    //将目标用户的ID列表添加到响应中，表示消息需要发送给哪些用户
                    for (const auto &id : target_list) {
                        response->add_target_id_list(id);
                    }

        }
