PHP Curl HMAC-SHA1

需要帮助….
我需要从URL调用来自API调用的json数据.
它说需要……

>内容类型：application / x-www-form-urlencoded
> HTTP HEADERS：key —> APIKEY
> HTTP HEADERS：sig —>带有SECRET KEY的POST数据的HMAC-SHA1签名
> POST PARAMETER：timestamp —->当前的Unix时间戳

我这样做是否正确？但是如何实现上面的第3点???

<code>$key = 'APIKEY';
$secret = 'APISECRET';
$signature = '';

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://www.domain.com/getticker");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_HEADER, FALSE);
curl_setopt($ch, CURLOPT_POST, TRUE);
curl_setopt($ch, CURLOPT_POSTFIELDS, "timestamp=".time());
curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-Type: application/x-www-form-urlencoded","key: ".$key,"sig: ".$signature));
$response = curl_exec($ch);
curl_close($ch);

echo $response;
</code>

一直在挠我的头.请帮我这个关于PHP的新手.

解决方法:

终于我明白了….
看到$签名部分.

<code>$key = 'APIKEY';
$secret = 'APISECRET';

$timestamp = time();
$signature = hash_hmac('sha1', "timestamp=".$timestamp, $secret);

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://www.domain.com/getticker");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_HEADER, FALSE);
curl_setopt($ch, CURLOPT_POST, TRUE);
curl_setopt($ch, CURLOPT_POSTFIELDS, "timestamp=".time());
curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-Type: application/x-www-form-urlencoded","key: ".$key,"sig: ".$signature));
$response = curl_exec($ch);
curl_close($ch);

echo $response;
</code>
