Roku Developer Program

I have this code chunk that does an API request and should save the response to a file, but it doesn't. 'channel' is a String.

plReq = CreateObject("roURLTransfer")
plReq.AddHeader("Client-ID", *my API key*)
plReq.SetURL("https://usher.twitch.tv/api/channel/hls/" + channel + ".m3u8?player=twitchweb&token=" + resp.token.tostr() + "&sig=" + resp.sig.tostr() + "&allow_audio_only=true&allow_source=true&type=any&p=" + "7333049")

' configure SSL certs
plReq.SetCertificatesFile("common:/certs/ca-bundle.crt")
plReq.AddHeader("X-Roku-Reserved-Dev-Id", "")
plReq.InitClientCertificates()

code = plreq.GetToFile("tmp:/" + channel + ".m3u8")

When I look in the debugger, I see that code = -3, so I assumed that there was something wrong with the GET Request.

code             Integer val:-3 (&hFFFFFFFD)

I then tried to print the url associated with plReq to see if it was being set properly and it seems like the url string is empty

The only thing I can think of is that SetUrl() expects a String, not a roString. But I am unsure of how to convert the object back to an intrinsic as I need to be able to concatenate to build the url in the first place. Any help is appreciated.

Just a guess, but .m3u8 is probably not a recognized extension. Try dropping it from the title and just use the channel var.  You actually don't need extensions when saving as far as the OS is concerned.

Just tried it, no dice. I also tried plreq.GetToString() just to see if there was any response at all, but the response string was empty and plreq.GetUrl() was also still empty.

code             roString (2.1 was String) refcnt=1 val:""

try it this way. 

plreq.GetToFile("tmp:/" + channel)
code = readAsciiFile( "tmp/"+channel)
? code

[mitchr181]

plreq.gettofile("tmp:/" + channel)
code = readasciifile("tmp:/" + channel)

Still nothing. Even though I'm using an old API, I don't think that's contributing to this problem. Even if the API was dead, I should still be able to see the url that I'm setting using plreq.geturl().

     fileName = "tmp:/" + name
    LocalFileBrowser = CreateObject("roFileSystem")

    ' to read
    if LocalFileBrowser.exists(fileName)
        text = ReadAsciiFile(fileName)
    else
        text = ""
    end if
 
    ' to write
    WriteAsciiFile(filename,text)

plReq = CreateObject("roURLTransfer")

Are you doing this on the render thread? It almost seems like you are since you say the URL you set is empty. You must create a task to run URL transfers within.
