小编Rai*_*Lai的帖子

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

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

$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;

一直在挠我的头.请帮我这个关于PHP的新手.
