qRPC简介
------

qRPC是一个基于TCP协议、基于Protobuf序列化和代码生成，跨语言的高效率轻量级RPC框架。

框架具有如下特点：

*   基于TCP协议的非阻塞IO(NIO)实现底层网络通信，吞吐量高。

*   基于Protobuf序列化，紧凑高效、高性能、跨语言、可拓展。

*   通过IDL（Interface Define Language）进行接口定义并生成代码

*   跨语言，支持Java、Go、C++、Python等多种语言

使用方法
----

需要了解RPC(Rmote Procedure Call)，会用Protobuf（[Proto3官方文档](https://protobuf.dev/programming-guides/proto3/ "Proto3官方文档")），如果你使用过Google gRPC，你将会非常容易上手。

#### Java:

*   引入Maven依赖

```
<dependency>
<groupId>io.github.barackyoung</groupId>
<artifactId>qrpc-core</artifactId>
<version>1.0.0.SNAPSHOT</version>
</dependency>
```

*   定义数据结构和服务接口

```
Syntax="proto3";
Option Java_Multiple_Files=false;
Option Java_Package="com.qrpc.demo";
Option Java_Outer_Classname="Demo";
Option Java_Generic_Services=true; 
Package qrpc.demo;

Message request {
    string message=1;
}

Message response {
    string message=1;
}
Service DemoService{
    Rpc sendMessage (request) returns (response) {};
}
```

*   生成数据结构和接口定义

```
Protoc -- java out=<path to your source root>-- proto path=<your proto path><proto filename>
```

*   服务端实现接口

```
Public class DemoServiceImpl extensions Demo.DemoService {
    @Overrides
    Public void sendMessage(RpcController controller, Demo.request request, RpcCallback<Demo.response> done){
        System.out.println("received from client, message:"+request. getMessage ());
        Demo.response response = Demo.response.newBuilder().setMessage("hi client").build();
        Done.run(response);
    }
}
```

*   客户端调用服务接口

```
Demo.requestrequest=Demo.request.newBuilder()
    .setMessage("hi, server!")
    .build();

//Synchronous call
UsageDemo.DemoService.BlockingInterface blockingStub=Demo.DemoService.newBlockingStub(SimpleBlockQRpcChannel.forAddress("127.0.0.1", 8888).build());
Demo.response response = blockingStub.sendMessage(null, request);
System.out.println("synchronous response:" + response.getMessage ());

//Asynchronous call
UsageDemo.DemoService.Stub stub = Demo.DemoService.newStub(SimpleQRpcChannel.forAddress("127.0.0.1", 8888).build());
Stub.sendMessage(null, request, new RpcCallback<Demo. response>() {
    @ Override
    Public void run(Demo.response parameter){
        System.out.println ("asynchronous response:"+response. getMessage ());
    }
});
```

#### Go: TODO

#### C++: TODO

待开发点
----

*   spring-boot-starter，springboot自动配置，支持与springboot无缝结合

*   服务治理（支持ectd、zookeeper等服务发现），负载均衡调用

*   配置系统，比如线程数等参数可配置

*   云原生相关支持

*   测试用例

提示
--

项目处于起步阶段，代码易读懂，欢迎广大社会程序员、学生一起加入，一起学习造轮子，把理论与实践相结合，一起提高！

Introduction to qRPC
------
QRPC is an efficient and lightweight RPC framework based on the TCP protocol, Protobuf serialization, and code generation, spanning multiple languages.
The framework has the following characteristics:
*    Non blocking IO (NIO) based on TCP protocol enables low-level network communication with high throughput.
*    Based on Protobuf serialization, it is compact, efficient, high-performance, cross language, and scalable.
*    Define interfaces and generate code through IDL (Interface Definition Language)
*    Cross language support for multiple languages such as Java, Go, C++, Python, etc

Usage
----
Need to understand RPC (Rmote Procedure Call) and use Protobuf ([Proto3 official document]（ https://protobuf.dev/programming-guides/proto3/ If you have used Google gRPC, it will be very easy for you to get started.
####Java:
*   Introducing Maven dependencies
```
<dependency>
<groupId>io.github.barackyoung</groupId>
<artifactId>qrpc-core</artifactId>
<version>1.0.0.SNAPSHOT</version>
</dependency>
```
*   Define data structures and service interfaces
```
Syntax="proto3";
Option Java_Multiple_Files=false;
Option Java_Package="com.qrpc.demo";
Option Java_Outer_Classname="Demo";
Option Java_Generic_Services=true; 
Package qrpc.demo;

Message request {
    string message=1;
}

Message response {
    string message=1;
}
Service DemoService{
    Rpc sendMessage (request) returns (response) {};
}
```
*   Generate data structures and interface definitions
```
Protoc -- java out=<path to your source root>-- proto path=<your proto path><proto filename>
```
*   Server implementation interface
```
Public class DemoServiceImpl extensions Demo.DemoService {
    @Overrides
    Public void sendMessage(RpcController controller, Demo.request request, RpcCallback<Demo.response> done){
        System.out.println("received from client, message:"+request. getMessage ());
        Demo.response response = Demo.response.newBuilder().setMessage("hi client").build();
        Done.run(response);
    }
}
```
*   Client Call Service Interface
```
Demo.requestrequest=Demo.request.newBuilder()
    .setMessage("hi, server!")
    .build();

//Synchronous call
UsageDemo.DemoService.BlockingInterface blockingStub=Demo.DemoService.newBlockingStub(SimpleBlockQRpcChannel.forAddress("127.0.0.1", 8888).build());
Demo.response response = blockingStub.sendMessage(null, request);
System.out.println("synchronous response:" + response.getMessage ());

//Asynchronous call
UsageDemo.DemoService.Stub stub = Demo.DemoService.newStub(SimpleQRpcChannel.forAddress("127.0.0.1", 8888).build());
Stub.sendMessage(null, request, new RpcCallback<Demo. response>() {
    @ Override
    Public void run(Demo.response parameter){
        System.out.println ("asynchronous response:"+response. getMessage ());
    }
});
```
#### Go: TODO
#### C++: TODO

Points to be developed
----
*    Spring boot starter, automatically configured for spring boot, supports seamless integration with spring boot
*    Service governance (supporting service discovery such as ectd and zookeeper), load balancing calls
*    Configure the system, such as configurable parameters such as thread count
*    Cloud native related support
*    Test Cases
