如何从grpc fi调用方法

Question

我已经用python（）中的grpc生成了两个文件，现在我想制作一个使用grpc方法的客户机。 第一步是创建存根：

grpcChannel = grpc.insecure_channel('https://.....')  
stub = garden_pb2_grpc.GardenServiceStub(grpcChannel)

现在我想用存根的方法，这样做：

^{pr2}$

问题是我不知道如何生成对象。所以我这样做：

^{3}$

它不起作用，因为我在createrequest中没有参数，但是我不知道在哪里可以找到它们（在我的grpc文件中，但是我不明白）。如何创建我的对象以及如何查看它所需的参数？因为我不知道两次函数的区别。在

我的文件：

My client: 

```
# example_consumer.py

import garden_pb2

# Access the CLODUAMQP_URL environment variable and parse it (fallback to localhost)

url = os.environ.get('CLOUDAMQP_URL', 'amqp://layana:layana321@localhost:5672')
params = pika.URLParameters(url)
connection = pika.BlockingConnection(params)
channel = connection.channel()  # start a channel
channel.queue_declare(queue='garden')  # Declare a queue
grpcChannel = grpc.insecure_channel('https://de.eu')  
stub = garden_pb2_grpc.GardenServiceStub(grpcChannel)  


test = garden_pb2.CreateRequest() #how can i create it ?

def garden_process_function(msg):
    print("Received " + str(msg))
    print("This function can do something")
    time.sleep(1)  # delays for 5 seconds
    feature = stub.Create(test) 
    return;


# create a function which is called on incoming messages
def callback(ch, method, properties, body):
    garden_process_function(body)


class Server(object):
    @staticmethod
    def receiveMsg():
        # set up subscription on the queue
        channel.basic_consume('garden',
                              callback,
                              auto_ack=True)
        # start consuming (blocks)
        channel.start_consuming()
        connection.close()


class App(object):
    @staticmethod
    def run():
        print('Running...')


if __name__ == '__main__':
    App.run()
    Server.receiveMsg()

```
```





How can I create my object and how can I see the arguments it needs? Because there are two times the same function in the file and I don't know the difference between the two.
