我最近找到一个国产的开源网关Apinto，纯go语言编写，并且支持多种协议转换。

我给你简单展示下http协议转dubbo协议，Apinto的安装步骤我就不展示了，只看效果。

Apinto地址如下：https://github.com/eolinker/apinto

准备好一个java的dubbo服务端

package cn.demo.model;public class User {String name;int id;Integer age;
}package cn.demo.api.UserService;import cn.demo.model.User;
import java.util.List;
import java.util.Map;public interface UserService {User sayHello(User user);//输入什么输出什么
}

接下来准备配置Apinto

• 创建一个全局的http转dubbo插件

curl -X POST  'http://127.0.0.1:9400/api/setting/plugin' \
-H 'Content-Type:application/json' \
-d '{"plugins":[{"id":"eolinker.com:apinto:http_to_dubbo2","name":"http-to-dubbo","status":"enable"}]
}'

• 创建一个上游服务，绑定dubbo服务

curl -X POST  \'http://127.0.0.1:9400/api/service' \-H 'Content-Type:application/json' \-d '{"name": "dubbo_service","driver": "http","description": "","timeout": 3000,"retry": 3,"scheme": "HTTP","nodes": ["127.0.0.1:20880"],"balance": "round-robin"
}'

• 创建一个http路由，绑定上游服务和http转dubbo协议的插件，并配置相关信息

curl -XPOST\'http://127.0.0.1:9400/api/router'\-H'Content-Type:application/json'\-d'{"name": "http_router","driver": "http","description": "","location": "/sayHello","rules": [],"plugins":{"http-to-dubbo":{"disable":false,"config":{"method":"sayHello","service":"com.demo.api.UserService","params":[{"class_name":"com.demo.model.User"}]}}},"service": "dubbo_service@service","template":""
}'

• 发起http请求测试

curl -X POST  \'http://127.0.0.1:8099/sayHello' \-H 'Content-Type:application/json' \-d '{"name": "xxx","id":10}'

• 执行后结果如下，表示转发成功啦
