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()
以上这篇使用XML库的方式,实现RPC通信的方法(推荐)就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持。
