1.5 基于xml的rpc调用

from xmlrpc.server import SimpleXMLRPCServer
class calculate:
    def add(self, x, y):
        return x + y
    def multiply(self, x, y):
        return x * y
    def subtract(self, x, y):
        return abs(x-y)
    def divide(self, x, y):
        return x/y
obj = calculate()
server = SimpleXMLRPCServer(("localhost", 8088))
# 将实例注册给rpc server
server.register_instance(obj)
print("Listening on port 8088")
server.serve_forever()

客户端

from xmlrpc import client
server = client.ServerProxy("http://localhost:8088")
print(server.add(2, 3))

然后，我们通过 server_proxy 对象就可以远程调用之前的rpc server的函数了。

>> server.add(2, 3)
5
>>> server.multiply(2, 3)
6
>>> server.subtract(2, 3)
1
>>> server.divide(2, 3)
0
