PHP Curl HMAC-SHA1

Question

需要帮助.... 我需要从URL调用来自API调用的json数据。 它说有需要......

1. 内容类型：application / x-www-form-urlencoded
2. HTTP HEADERS：key ---＆gt; APIKEY
3. HTTP HEADERS：sig ---＆gt;带有SECRET KEY的POST数据的HMAC-SHA1签名
4. POST PARAMETER：timestamp ----＆gt;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???

$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;

一直在摸不着头脑。请帮助我这个关于PHP的新手。

Answer 1

最后我明白了...... 看到$签名部分。

$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;
