python调用dubbo接口的实现步骤

pip install dubbo3
# 用于编译.proto文件，生成Python代码
pip install grpcio-tools

syntax = "proto3";
 
package example;
 
service Greeter {
  rpc SayHello (HelloRequest) returns (HelloReply);
}
 
message HelloRequest {
  string name = 1;
}
 
message HelloReply {
  string message = 1;
}

python -m grpc_tools.protoc -I. --python_out=. --grpc_python_out=. greeter.proto

from dubbo3 import DubboServer
from greeter_pb2 import HelloReply
from greeter_pb2_grpc import GreeterServicer
 
class GreeterService(GreeterServicer):
    async def SayHello(self, request, context):
        # 这里是你的核心业务逻辑
        return HelloReply(message=f"Hello, {request.name}!")
 
if __name__ == '__main__':
    server = DubboServer()
    server.register_service(GreeterService())
    server.start()

# config.yaml
application:
  name: python-dubbo-provider
registries:
  nacos:
    protocol: nacos
    address: 127.0.0.1:8848
protocols:
  triple:
    port: 50051

from dubbo3 import DubboServer
from greeter_pb2_grpc import GreeterServicer
# ... 其他导入
 
server = DubboServer()
server.load_config('config.yaml') # 加载配置文件
server.register_service(GreeterService())
server.start()

# 示例：使用 dubbo-client-py 提供 Dubbo 服务
from dubbo_client import ZkRegister
# ... 定义服务接口和实现类 ...
# register = ZkRegister('localhost:2181')
# register.register('com.example.HelloService', HelloServiceProvider())
