xmlrpc库 PHP,教你怎么使用XML库实现RPC通信的功能

1、先说结论：使用xml-rpc的机制可以很方便的实现服务器间的RPC调用。

2、试验结果如下：

3、源码如下：

服务器端的源代码如下：

import operator, math

from SimpleXMLRPCServer import SimpleXMLRPCServer

from functools import reduce

def main():

server = SimpleXMLRPCServer(('127.0.0.1', 7001))

server.register_introspection_functions()

server.register_multicall_functions()

server.register_function(addtogether)

server.register_function(quadratic)

server.register_function(remote_repr)

print("Server ready")

server.serve_forever()

def addtogether(*things):

"""Add together everything in the list things ."""

return reduce(operator.add, things)

def quadratic(a, b, c):

"""Determine x values satisfying: a * x * x + b * x + c = 0"""

b24ac = math.sqrt(b*b - 4.0*a*c)

return list(set([(-b-b24ac) / 2.0*a, (-b+b24ac) / 2.0*a]))

def remote_repr(arg):

"""return the repr() rendering of the supplied arg """

return arg

if __name__ == '__main__':

main()

客户端的代码如下：

import xmlrpclib

def main():

proxy = xmlrpclib.ServerProxy('http://127.0.0.1:7001')

print("Here are the functions supported by this server:")

print("next calculator addtogether: ")

print(proxy.addtogether('x','y','z'))

print(proxy.addtogether('x','y','z'))

print(proxy.addtogether('x','y','z'))

print(proxy.addtogether('x','y','z'))

for method_name in proxy.system.listMethods():

if method_name.startswith('system.'):

continue

signatures = proxy.system.methodSignature(method_name)

if isinstance(signatures, list) and signatures:

for signature in signatures:

print('%s(%s)' %(method_name, signature))

else:

print('%s(...)' %(method_name,))

method_help = proxy.system.methodHelp(method_name)

#if method_help:

# print(' ', methodHelp)

print(proxy.addtogether('x','y','z'))

print("addtogether result ")

if __name__ == '__main__':

main()
