Http Response to shoutcast - ZxPwn420 - 17.06.2011

So I figured that since SHOUTcast displays it's stats in the form of a HTML file, i'd be able to grab the contents of it using the Http request function recently implemented to display the currently playing song using a command.

SHOUTcast outputs it's stats here: http://<IP>:<PORT>/7.html

However, on trying this out, I get the response code 7 which is HTTP_ERROR_MALFORMED_RESPONSE.

Any ideas?

You must make an error somewhere, try to do this (you can do it with telnet, too):
(replace Server: and host and port with the shoutcast server's details)

Quote:

C:\Documents and Settings\user>ncat radio.xyz.com 8048
GET /7.html HTTP/1.1
User-Agent: Mozilla/5.0 (Compatible: lolscript 0.1)
Server: radio.xyz.com

You have to get an answer like this:

Quote:

HTTP/1.0 200 OK
content-type:text/html

<HTML><meta http-equiv="Pragma" content="no-cache"></head><body>76,1,225,3000,76
,128,Artist - Music</body></html>

If you get this answer, check your use of the HTTP library.

Thanks for the advice. I've setup pretty much everything now, all I need to do is parse the numbers after each ',' character to retrieve current listeners, current bitrate and current song playing.

EDIT:

Finally, got everything working!

pawn Код:

forward StreamHttpResponse(playerid, response_code, data[]);

enum STREAMDATA
{
    CURRENTLISTENERS,
    STREAMSTATUS,
    PEAKLISTENERS,
    MAXLISTENERS,
    UNIQUELISTENERS,
    BITRATE,
    SONGTITLE[32]
}

...

if(strcmp(cmd, "/radiostatus", true) == 0)
{
    HTTP(playerid, HTTP_GET, "PHP SCRIPT THAT GRABS 7.HTML", "", "StreamHttpResponse");
    return 1;
}

...

public StreamHttpResponse(playerid, response_code, data[])
{
    new buffer[128];
    if(response_code == 200)
    {
        new stream[STREAMDATA];
        strdel(data, 0, 3);
        sscanf(data, "p<,>e<iiiiiis[32]>", stream);
        SendClientMessage(playerid, COLOR_RED, "Radio Status");
        SendClientMessage(playerid, COLOR_RED, "============");
        format(buffer, sizeof(buffer), "Listeners: %d of %d (at %dkbps)", stream[UNIQUELISTENERS], stream[MAXLISTENERS], stream[BITRATE]);
        SendClientMessage(playerid, COLOR_GREEN, buffer);
        format(buffer, sizeof(buffer), "Current Song: %s", stream[SONGTITLE]);
        SendClientMessage(playerid, COLOR_GREEN, buffer);
    }
    else
    {
        SendClientMessage(playerid, COLOR_RED, "[Error] The radio must be down or there is a temporary error!");
    }
}

Works flawlessly.
