使用jsonrpclib编写RPC

服务端代码

#coding=utf-8
__author__ = 'nate'

import string
from jsonrpclib.SimpleJSONRPCServer import SimpleJSONRPCServer
from datetime import datetime


class Api:
	def __init__(self):
		self.string = string

	def test(self):
		return 'this is test at {now}'.format(now=datetime.now())


def add(a, b):
	return a + b

if __name__ == '__main__':
	try:
		port = 8080
		server = SimpleJSONRPCServer(('127.0.0.1', port))
		server.register_function(add)
		server.register_instance(Api(), allow_dotted_names=True)
		print 'listening on port %d' % port
		server.serve_forever()
	except KeyboardInterrupt:
		print 'Exit'

客户端代码

#coding=utf-8
__author__ = 'nate'

import jsonrpclib
from jsonrpclib.jsonrpc import ProtocolError

if __name__ == '__main__':
	try:
		server = jsonrpclib.Server('http://localhost:8080')
		# test function
		print server.add(5, 6)
		print jsonrpclib.history.request
		print jsonrpclib.history.response

		# test instance
		print server.test()
		print server.string.join([str(i) for i in xrange(1, 10)], '*')

		# multiple call
		multi = jsonrpclib.MultiCall(server)
		multi.add(7, 8)
		multi.test()
		multi.string.join([str(i) for i in xrange(10, 20)], '#')
		results = multi()
		for result in results:
			print result

	except ProtocolError, error:
		print 'error : {err}'.format(err=error)
