***solved*** ASyncGetToFile fails immediately?

I have a URL (.cgi script) which is returning a .jpeg file. I can copy/paste the URL into my browser and see the image without issue.

But… when I pull that same URL via this code, it returns an INVALID event immediately.


' agent for transferring files
    agent = CreateObject("roUrlTransfer")
    agent.SetUrl(settings.Url)
    
    print "About to AsyncGetToFile: "; settings.Url; " "; tmpFile
    
    ' get it
    if (agent.AsyncGetToFile(tmpFile) = false) then
        print "AsyncGetToFile never even started!"
    end if
    
    event = wait(30000,agent.GetMessagePort())
    
    if type(event) = "roUrlEvent"
        print "***";event.GetInt();
        print "***";event.GetResponseCode();
        print "***";event.GetFailureReason();
        print "***";event.GetSourceIdentity()
    else if event = invalid
        print "AsyncGetToFile timeout"
        agent.AsyncCancel()
    else
        print "AsyncGetToFile unknown event: "; event
    endif

I’ve seen some code using agent.GetPort() instead but the reference at http://sdkdocs.roku.com/display/sdkdoc/roUrlTransfer only lists GetMessagePort()

Any help is appreciated.

    agent = CreateObject("roUrlTransfer")
    agentPort = CreateObject("roMessagePort")
    agent.SetMessagePort(agentPort)
    agent.SetUrl(settings.Url)

You need to create a message port and call agent.SetMessagePort().

You’re good people! I’m getting a different error now but at least I can tell it’s trying to make a connection.

Thanks!
