Need help with cUrl on roku

This works just fine from command line.

 curl 'https://api.blah.com/ath/link' \
  -d 'client_id=lOnGStringOfCharacters' \
  -d 'client_secret=reallyreallylongstringofcharacters' \
  -d 'grant_type=password' \
  -d 'username=blabla@blababla.com' \
  -d 'password=s0mth1ng' 
  -d 'redirect_uri=http://myblah.com/fail'


Any suggestions on how to convert this into a url to POST and or GET using roURlXfer?

Would the \ be converted to an ampersand? or the -d ? I tried putting it all on one line with ampersands and it was no-go, whereas cUrling it worked perfectly.

    Yes, with an "&". The POST string should look pretty much identical to a querystring, without the leading "?". Note that, typically, it should also be URL encoded like a querystring, as well.

    urlTransfer = CreateObject("roUrlTransfer")
    urlTransfer.SetUrl("https://api.blah.com/ath/link")
    urlTransfer.AddHeader("Content-Type", "application/x-www-form-urlencoded")
    result = urlTransfer.PostFromString("client_id=lOnGStringOfCharacters&client_secret=reallyreallylongstringofcharacters&grant_type=password&username=blabla%40blababla.com&password=s0mth1ng&redirect_uri=http%3a%2f%2fmyblah.com%2ffail")

    Hi Endless, thanks.

    One more question: how do I get the response information from this POST? postfromstring just returns an integer, not the response info I get with cUrl on the command line.

    Use the Async version to get more detailed info returned....

    From the event below you could query for the info you want like GetResponseHeadersArray()

    --Kevin

    Example:

    Function http_post_from_string_with_timeout(val As String, seconds as Integer) as String
        timeout% = 1000 * seconds

        str = ""
    '    m.Http.EnableFreshConnection(true) 'Don't reuse existing connections
        if (m.Http.AsyncPostFromString(val))
            event = wait(timeout%, m.Http.GetPort())
            if type(event) = "roUrlEvent"
    			print "1"
    			str = event.GetString()
            elseif event = invalid
    			print "2"
                Dbg("AsyncPostFromString timeout")
                m.Http.AsyncCancel()
            else
    			print "3"
                Dbg("AsyncPostFromString unknown event", event)
            endif
        endif

        return str
    End Function
