New subject: [Lava-users] zmq example not work

18 Jan 2019


      Just use the sample command "python zmq_client.py -j 357 --hostname tcp://127.0.0.1:5500 -t 1200"
Get the error:

I wonder for following code, why http://tcp://127.0.0.1:5500/RPC2 will finally be passed to ServerProxy?
If I remove http, just tcp://127.0.0.1:5500/RPC2, it will say "OSError: unsupported XML-RPC protocol"
If I remove tcp, just http://127.0.0.1:5500/RPC2, it will hang in get_publisher_event_socket
I use 2018.11 version, please suggest!!!
xmlrpc_url = "http://%s/RPC2" % (hostname)
    if https:
        xmlrpc_url = "https://%s/RPC2" % (hostname)
    server = xmlrpc.client.ServerProxy(xmlrpc_url)
    try:
        socket = server.scheduler.get_publisher_event_socket()
