ZeroRPC和SimpleXMLRPCServer

一、Python中RPC框架

自带的:SimpleXMLRPCServer(数据包大，速度慢)

第三方：ZeroRPC(底层使用ZeroMQ和MessagePack，速度快，响应时间短，并发高)，grpc(谷歌推出支持夸语言)

二、SimpleSMLRPCServer使用

服务端

from xmlrpc.server import SimpleXMLRPCServer
class RPCServer(object):

    def __init__(self):
        super(RPCServer, self).__init__()
        print(self)
        self.send_data = 'lqz nb'
        self.recv_data = None

    def getObj(self):
        print('get data')
        return self.send_data

    def sendObj(self, data):
        print('send data')
        self.recv_data = data
        print(self.recv_data)
# SimpleXMLRPCServer
server = SimpleXMLRPCServer(('localhost',4242), allow_none=True)
server.register_introspection_functions()
server.register_instance(RPCServer())
server.serve_forever()

客户端

import time
from xmlrpc.client import ServerProxy

# SimpleXMLRPCServer
def xmlrpc_client():
    print('xmlrpc client')
    c = ServerProxy('http://localhost:4242')
    data = 'lqz nb'
    start = time.clock()
    for i in range(500):
        a=c.getObj()
        print(a)
    for i in range(500):
        c.sendObj(data)
    print('xmlrpc total time %s' % (time.clock() - start))

if __name__ == '__main__':
    xmlrpc_client()

三、ZeroRPC使用

服务端

import zerorpc

class RPCServer(object):

    def __init__(self):
        super(RPCServer, self).__init__()
        print(self)
        self.send_data = 'lqz nb'
        self.recv_data = None

    def getObj(self):
        print('get data')
        return self.send_data

    def sendObj(self, data):
        print('send data')
        self.recv_data = data
        print(self.recv_data)
# zerorpc
s = zerorpc.Server(RPCServer())
s.bind('tcp://0.0.0.0:4243')
s.run()

客户端

import zerorpc
import time
# zerorpc
def zerorpc_client():
    print('zerorpc client')
    c = zerorpc.Client()
    c.connect('tcp://127.0.0.1:4243')
    data = 'lqz nb'
    start = time.clock()
    for i in range(500):
        a=c.getObj()
        print(a)
    for i in range(500):
        c.sendObj(data)

    print('total time %s' % (time.clock() - start))


if __name__ == '__main__':
    zerorpc_client()
