Thanks to share this. Please do you have an example ? An example of one command line...

./xmlrpc-client.sh -t [arg1 arg2 ...]

@joel-depiltech: For simple types it is ./xmlrpc-client.sh --verbose --target "https://api.host.name" -- methodName key1:value1 key2:value2 .... I’m still struggling with the struct type. I just don’t know what the line : parse wait complete ... should do.

thanks a lot. This is my example.

I run server.py on linux, and use this shell script like this.

./xmlrpc_client.sh -t "xx.xx.xx.xx:8085" -- add int:1 int:2

the server.py is like this:

from xmlrpc.server import SimpleXMLRPCServer
# from SimpleXMLRPCServer import SimpleXMLRPCServer
def add(x, y):
    return x + y
if __name__ == '__main__':
    s = SimpleXMLRPCServer(('xx.xx.xx.xx', 8085))
    s.register_function(add)
    s.serve_forever()

Super!
