一、前置准备

在开始签名之前，需要准备以下信息：

Access Key ID（AK）：请求火山引擎OpenAPI的安全凭证之一。
Secret Access Key（SK）：与AK成对使用，用于签名计算。
请求参数：包括HTTP请求方法、URI、查询参数、请求头等。

二、签名流程(文档地址)

火山引擎API签名流程大致分为以下几个步骤：

创建规范请求：将请求参数进行规范化处理，形成CanonicalRequest。
创建待签名字符串：基于CanonicalRequest和其他元数据信息，构建StringToSign。
派生签名密钥：从SK派生出签名密钥（signing key）。
计算签名：使用HMAC-SHA256算法和签名密钥，计算StringToSign的签名。
构建Authorization头：将签名和其他必要信息添加到请求头中。

三、具体实现

以下是一个PHP示例代码，火山引擎API请求生成签名：

/**** Author:刘星麟* @param $ak   Access Key ID* @param $sk   Secret Access Key* @param $region   服务Region* @param $service  服务名称* @param $body     请求参数 没有给空* @param $query    接口请求参数* @param $method   请求方法  GET|POST* @param $path     服务路径* @param $headers  服务请求header  签名必要  https://www.volcengine.com/docs/6369/67268#_2-%E7%AD%BE%E5%90%8D%E5%8F%82%E6%95%B0* @return mixed*/
function signv4($ak, $sk, $region, $service, $body, $query, $method, $path, $headers)
{if ($path === '') {$path = '/';}$ldt = gmdate('Ymd\THis\Z');$sdt = substr($ldt, 0, 8);$headers['X-Date'] = $ldt;$bodyHash = hash('sha256', $body);$headers['X-Content-Sha256'] = $bodyHash;$credentialScope = "$sdt/$region/$service/request";$signedHeaders = [];foreach ($headers as $key => $value) {if ($key == "Host" || $key == "Content-Md5" || $key == "Content-Type" || substr($key, 0, 2) == "X-") {$key = strtolower($key);$signedHeaders[$key] = $value;}}ksort($signedHeaders);$signed_str = '';foreach ($signedHeaders as $k => $v) {$signed_str .= $k . ':' . $v . "\n";}$signedHeadersString = implode(';', array_keys($signedHeaders));$canon = implode("\n", array($method, $path, $query, $signed_str, $signedHeadersString, $bodyHash));$hash = hash('sha256', $canon);$toSign = implode("\n", array("HMAC-SHA256", $ldt, $credentialScope, $hash));$signingKey = getSigningKey($sdt, $region, $service, $sk);$signature = hash_hmac('sha256', $toSign, $signingKey);$credential = $ak . '/' . $credentialScope;$headers['Authorization'] = "HMAC-SHA256 Credential={$credential}, SignedHeaders={$signedHeadersString}, Signature={$signature}";return $headers;
}function getSigningKey($date, $region, $service, $sk)
{$dateKey = hash_hmac('sha256', $date, $sk, true);$regionKey = hash_hmac('sha256', $region, $dateKey, true);$serviceKey = hash_hmac('sha256', $service, $regionKey, true);return hash_hmac('sha256', 'request', $serviceKey, true);
}

四：演示：获取余额

function curl_data($url, $header = [])
{//初始化$ch = curl_init();// 请求头，可以传数组curl_setopt($ch, CURLOPT_URL, $url);curl_setopt($ch, CURLOPT_HTTPHEADER, $header);curl_setopt($ch, CURLOPT_HEADER, false);curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);curl_setopt($ch, CURLOPT_TIMEOUT, 10);           //最大相应超时时间curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); // 跳过证书检查curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false); // 不从证书中检查SSL加密算法是否存在$output = curl_exec($ch);curl_close($ch);return $output;
}$host = 'open.volcengineapi.com';
$service = 'billing';          // 服务名称
$region = 'cn-beijing';        // 区域
$version = '2022-01-01';       // API版本
$action = 'QueryBalanceAcct';  // 操作名称
$path = '/';
$method = 'GET';
$httpBody = '';                 //请求的参数$ak = 'AKLTM***************************TI';
$sk = 'TV*************************************bE9XVQ==';//查询参数
$query = http_build_query(['Action' => $action,'Version' => $version
]);$url = 'https://' . $host . $path . ($query ? "?{$query}" : ''); //组装请求的地址//请求header
$headers = ['Host' => $host
];$headerArr = signv4($ak, $sk, $region, $service, $httpBody, $query, $method, $path, $headers);
$header = [];
foreach ($headerArr as $k => $v) {$header[] = $k . ":" . $v;
}$resString = curl_data($url, $header);

正常数据返回格式
