Python使用RPC例子

from multiprocessing import Pool
from rpyc import Service  
from rpyc.utils.server import ThreadedServer  
  
class RemoteService(Service):  
 
    def on_connect(self, conn):
        print(conn)
 
    '''供客户端调用的方法前得加exposed_'''
    def exposed_search(self, data):  
        print(data)
        data['result'] = 'ok'
        return data  
 
def main(port):
    sr = ThreadedServer(service=RemoteService, hostname='127.0.0.1', port=port, auto_reGISter=False)  
    print(f'Server IP: {(sr.host,sr.port)}')
    sr.start()  
 
if __name__ == '__main__':
    pool = Pool(processes=2)
    pool.apply_async(main, args=(9998,))
    pool.apply_async(main, kwds={'port':9999})
    pool.close()
    pool.join()

import rpyc
import time
from multiprocessing import Pool
 
def search_db(query,port):
    conn = rpyc.connect('localhost',port)
    '''调用时省略exposed_'''
    result = conn.root.search(query)
    time.sleep(1)
    print(result)
    conn.close()
 
if __name__ == '__main__':
    pool = Pool(processes=2)
    pool.apply_async(search_db, args=({"match": {'name': 'user'}}, 9998))
    pool.apply_async(search_db, kwds={'query': {"match": {'name': 'user'}},'port':9999})
    pool.close()
    pool.join()
