使用XML库的方式,实现RPC通信的方法(推荐)

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()
