# 简介
一个简单的rpc通信框架，基于c++和protobuf实现。
# 使用说明
## 环境准备
protobuf、gdb、muduo、boost、zookeeper服務器和庫
### zookeeper
庫
```angular2html
sudo apt-get install libzookeeper-mt2
```
服務器

頭文件
```angular2html
sudo apt-get install libzookeeper-mt-dev
```
## 使用准备
以一个最简单的获取frinedList功能为例介绍，介绍如何使用。
step1：rpc通信需要序列化和反序列化，这个过程依赖protobuf，因此先要编写protobuf所需的`protoc`文件。文件在example/friend.proto中。
注意：因为还使用到了protobuf提供的服务（stub）功能，因此需要设置：`option cc_generic_services = true;`
step2:使用protobuf生成pb文件:`protoc --cpp_out=./ friend.proto`，可以看到已经生成了对应的pb.h和pb.cc文件(`example/friend.pb.cc`)。
step3：编写对应的friendservice.cc文件
```c++
#include
#include
#include "friend.pb.h"
#include "mprpcapplication.h"
#include "rpcprovider.h"
#include
#include "logger.h"
class FriendService : public fixbug::FiendServiceRpc
{
public:
std::vector GetFriendsList(uint32_t userid)
{
std::cout << "do GetFriendsList service! userid:" << userid << std::endl;
std::vector vec;
vec.push_back("gao yang");
vec.push_back("liu hong");
vec.push_back("wang shuo");
return vec;
}
// 重写基类方法
void GetFriendsList(::google::protobuf::RpcController* controller,
const ::fixbug::GetFriendsListRequest* request,
::fixbug::GetFriendsListResponse* response,
::google::protobuf::Closure* done)
{
uint32_t userid = request->userid();
std::vector friendsList = GetFriendsList(userid);
response->mutable_result()->set_errcode(0);
response->mutable_result()->set_errmsg("");
for (std::string &name : friendsList)
{
std::string *p = response->add_friends();
*p = name;
}
done->Run();
}
};
int main(int argc, char **argv)
{
// LOG_ERR("log ");
LOG_INFO("log start");
// 调用框架的初始化操作
MprpcApplication::Init(argc, argv);
// provider是一个rpc网络服务对象。把UserService对象发布到rpc节点上
RpcProvider provider;
provider.NotifyService(new FriendService());
// 启动一个rpc服务发布节点 Run以后，进程进入阻塞状态，等待远程的rpc调用请求
provider.Run();
return 0;
}
```
step4: 编译文件，依次执行命令。
```bash
swx@swx-virtual-machine1:~/mprpc$ ls
autobuild.sh bin build CMakeLists.txt example experiment lib README.md src test
swx@swx-virtual-machine1:~/mprpc$ cd build/
swx@swx-virtual-machine1:~/mprpc/build$ ls
CMakeCache.txt CMakeFiles cmake_install.cmake example Makefile src

```
step5:在bin中已经生成了对应的服务提供者和消费者，运行即可。
