Question

我正在尝试使用bitfinex API。

我在PhP编程，所有文档都是JS或Ruby（我真的需要学习更多Ruby）。

我可以提取用户信息，但我无法提取订单

代码：

<?php

function bitfinex_query($path, array $req = Array())
{
        global $config;
        // API settings, add your Key and Secret at here

        $key = "xxxxxxxxx";
        $secret = "xxxxxxxx";

        // generate a nonce to avoid problems with 32bits systems
        $mt = explode(' ', microtime());
        $req['request'] = "/v1".$path;
        $req['nonce'] = $mt[1].substr($mt[0], 2, 6);

        // generate the POST data string
        $post_data = base64_encode(json_encode($req));

        $sign = hash_hmac('sha384', $post_data, $secret);

        // generate the extra headers
        $headers = array(
                        'X-BFX-APIKEY: '.$key,
                        'X-BFX-PAYLOAD: '.$post_data,
                        'X-BFX-SIGNATURE: '.$sign,
        );

        // curl handle (initialize if required)
        static $ch = null;
        if (is_null($ch)) {
                $ch = curl_init();
                curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
                curl_setopt($ch, CURLOPT_USERAGENT,
                'Mozilla/4.0 (compatible; Bter PHP bot; '.php_uname('a').'; PHP/'.phpversion().')'
                );
        }

        curl_setopt($ch, CURLOPT_URL, 'https://api.bitfinex.com/v1'.$path);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);
        curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);

        // run the query
        $res = curl_exec($ch);

        if ($res === false) throw new Exception('Curl error: '.curl_error($ch));
        //echo $res;
        $dec = json_decode($res, true);
        if (!$dec) throw new Exception('Invalid data: '.$res);
        return $dec;
}



//this works
$api_name = '/orders';
$openorders = bitfinex_query($api_name);
var_dump($openorders);

//broken
$api_name = '/book/BTCUSD';
$orderbook = bitfinex_query($api_name);
//$orderbook = bitfinex_query($api_name, array("limit_asks"=> 1, "group"=> 0));


?>

输出：

array(1) {
  [0]=>
  array(16) {
    ["id"]=>
    int(880337054)
    ["symbol"]=>
    string(6) "btcusd"

  }
}

如何正确访问bitfinex api订单？

Answer 1

看起来你没有达到正确的终点。订单也是公开的。您的示例适用于经过身份验证的端点，例如进行交易。对于公共端点，您不需要SHA384或base64任何内容，您可以只执行简单的curl甚至file_get_contents。

这是订单簿的端点：https://api.bitfinex.com/v1/book/BTCUSD

现在你可以从那里做你喜欢的事。

cURL

$curl = "https://api.bitfinex.com/v1/book/BTCUSD";
$ch = curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_URL, $curl);
$ccc = curl_exec($ch);
print_r($ccc);

这只会抛弃一切。或者，您可以使用foreach循环将所有要求和出价解析为表格。以下是file_get_contents的示例，您当然可以使用cURL执行此操作。

file_get_contents Fiddle example

$fgc = json_decode(file_get_contents("https://api.bitfinex.com/v1/book/BTCUSD"), true);
echo "<table><tr><td>Bids</td><td>Asks</td></tr>";
$bids = $fgc["bids"];
echo "<tr><td valign='top'>";
foreach($bids as $details){
    echo "$".$details["price"]." - ".$details["amount"];
    echo "<br>";
}
echo "</td><td valign='top'>";
$asks = $fgc["asks"];
foreach($asks as $askDetails){
    echo "$".$askDetails["price"]." - ".$askDetails["amount"];
    echo "<br>";
}
echo "</td></tr></table>";

无法提取订单，bitfinex api
