It's so easy to love RPC.
Modern C++开发的RPC库就是这么简单好用!
# rest_rpc简介
rest_rpc是一个高性能、易用、跨平台、header only的c++11 rpc库,它的目标是让tcp通信变得非常简单易用,即使不懂网络通信的人也可以直接使用它。它依赖header-only的standalone [asio](https://github.com/chriskohlhoff/asio)(commit id:f70f65ae54351c209c3a24704624144bfe8e70a3)
可以快速上手,使用者只需要关注自己的业务逻辑即可。

# rest_rpc的特点
## 易
rest_rpc为用户提供了非常简单易用的接口,几行代码就可以实现rpc通信了,来看第一个例子
### 一个加法的rpc服务
```
//服务端注册加法rpc服务struct dummy{
int add(rpc_conn conn, int a, int b) { return a + b; }
};int main(){
rpc_server server(9000, std::thread::hardware_concurrency());dummy d;
server.register_handler("add", &dummy::add, &d);
server.run();
}
``````
//客户端调用加法的rpc服务
int main(){
rpc_client client("127.0.0.1", 9000);
client.connect();int result = client.call("add", 1, 2);
client.run();
}
```### 获取一个对象的rpc服务
```
//服务端注册获取person的rpc服务//1.先定义person对象
struct person {
int id;
std::string name;
int age;MSGPACK_DEFINE(id, name, age);
};//2.提供并服务
person get_person(rpc_conn conn) {
return { 1, "tom", 20 };
}int main(){
//...
server.register_handler("get_person", get_person);
}
``````
//客户端调用获取person对象的rpc服务
int main(){
rpc_client client("127.0.0.1", 9000);
client.connect();
person result = client.call("get_person");
std::cout << result.name << std::endl;
client.run();
}
```## 酷
异步?
同步?
future?
callback?
当初为了提供什么样的接口在社区群里还争论了一番,有人希望提供callback接口,有人希望提供future接口,最后我
决定都提供,专治强迫症患者:)现在想要的这些接口都给你提供了,你想用什么类型的接口就用什么类型的接口,够酷吧,让我们来看看怎么用这些接口吧:
```
//服务端提供echo服务
std::string echo(rpc_conn conn, const std::string& src) {
return src;
}server.register_handler("echo", echo);
```客户端同步接口
```
auto result = client.call("echo", "hello");
```客户端异步回调接口
```
client.async_call("echo", [](asio::error_code ec, string_view data){
auto str = as(data);
std::cout << "echo " << str << '\n';
});
```## async_call接口说明
有两个重载的async_call接口,一个是返回future的接口,一个是带超时的异步接口。返回future的async_call接口:
```
std::future future = client.async_call("echo", "purecpp");
```带超时的异步回调接口:
```
async_call("some_rpc_service_name", callback, service_args...);
```如果不显式设置超时时间的话,则会用默认的5s超时.
```
async_call("some_rpc_service_name", callback, args...);
``````
client.async_call("echo", [](asio::error_code ec, string_view data) {
if (ec) {
std::cout << ec.message() <<" "<< data << "\n";
return;
}auto result = as(data);
std::cout << result << " async\n";
}, "purecpp");
```客户端异步future接口
```
auto future = client->async_call("echo", "hello");
auto status = future.wait_for(std::chrono::seconds(2));
if (status == std::future_status::timeout) {
std::cout << "timeout\n";
}
else if (status == std::future_status::ready) {
auto str = future.get().as();
std::cout << "echo " << str << '\n';
}
```除了上面的这些很棒的接口之外,更酷的是rest_rpc还支持了订阅发布的功能,这是目前很多rpc库做不到的。
服务端订阅发布的例子在这里:
https://github.com/qicosmos/rest_rpc/blob/master/examples/server/main.cpp#L121
https://github.com/qicosmos/rest_rpc/blob/master/examples/client/main.cpp#L383## 快
rest_rpc是目前最快的rpc库,具体和grpc和brpc做了性能对比测试,rest_rpc性能是最高的,远超grpc。
性能测试的结果在这里:

# rest_rpc的更多用法
可以参考rest_rpc的example:
https://github.com/qicosmos/rest_rpc/tree/master/examples
# future
make an IDL tool to genrate the client code.
