Teach you how to use the XML library to implement RPC communication capabilities

1, first say the conclusion: the use of XML-RPC mechanism can be very convenient to implement RPC calls between servers.

2. The test results are as follows:

3. The source code is as follows:

The source code for the server side is as follows:

Import operator, Mathfrom simplexmlrpcserver import simplexmlrpcserverfrom functools import reducedef 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 ()

The code for the client is as follows:

Import Xmlrpclibdef Main (): Proxy = Xmlrpclib. Serverproxy (' http://127.0.0.1:7001 ') print ("Here is the functions supported by this server:") print ("Next C Alculator addtogether: ") Print (Proxy.addtogether (' x ', ' y ', ' z ')) print (Proxy.addtogether (' x ', ' y ', ' z ')) print (p         Roxy.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.methodSigna                Ture (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 (", method Help) Print (Proxy.addtogether (' x ', ' y ', ' z ')) print ("Addtogether result") If __name__ = = ' __main__ ': Main ()
