Print Page - Last price from Mt Gox json

Title: Last price from Mt Gox json
Post by: Jeremy West spendbitcoins.com on August 07, 2011, 08:15:43 PM

Can anyone help? I'm trying to grab the last price from Mt Gox using the following code:

<?php
$url = 'https://mtgox.com/api/0/data/ticker.php';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_REFERER, $url);
$json = curl_exec($ch);
curl_close($ch);
echo $json;//['ticker']['last'];
?>

and it's just hanging. Can anyone spot an error or if it's completely wrong just give me the right code? 1 BTC bounty if it works!

Thanks!

Here's what I usually use

Code:

<?php
$a=ouvrirpage("https://mtgox.com/code/data/ticker.php");
$res=json_decode($a, true);
echo $res['ticker']['last'];


function ouvrirpage($site){
	$ch = curl_init($site);
	curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.1) Gecko/20061204 Firefox/2.0.0.1");
	curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
	$res = curl_exec($ch);
	curl_close($ch);
	return $res;
}
?>

Maybe MtGox needs an useragent header

Yeah, you should use https://mtgox.com/code/data/ticker.php ... The URL that you use requires logging in.

I read somewhere too that useragents that actually send a useragent field might be favoured over those that do not?

(Dunno if bots would actually be requred to pretend to be (vanilla ?) browsers in order to be permitted to use the bot-enabling API though, has anyone tried being honest about which version of which bot is making the request?)

acutally a user agent seems not to be required. In my android App I don't use one either. And It would not really make sense, at least when using the MtGox API, as this one is intended for non-browser traffic

Just wanted to get it out there, BOTs are easily written to appear as browsers or even do it the dirty way and run in the browser.

The useragent is configurable in the HTTP headers that you send with the request. Also, MT.Gox likes a unique user-agent.

Code:

<?php
$opts = array(
  'http'=> array(
    'method'=>   "GET",
    'user_agent'=>    "MozillaXYZ/1.0"));
$context = stream_context_create($opts);
$json = file_get_contents('https://mtgox.com/code/data/ticker.php', false, $context);
$json = json_decode($json);
echo $json->{'ticker'}->{'last'};
?>

Sorry, forgot to post here that I already got this working with help from another thread. Thanks!
