业务接入示例

统一接口 POST /api/v1/upload,表单字段 file, 需携带 X-App-Key、X-Timestamp、 X-Nonce、X-Signature

待签名字符串(用 \n 换行拼接): METHOD \n PATH \n TIMESTAMP \n NONCE \n SHA256(文件内容)

PHP
$file   = 'a.jpg';                 // 也支持 mp4 / apk 等任意已授权格式
$key    = '你的 AppKey';
$secret = '你的 AppSecret';
$path   = '/api/v1/upload';
$ts     = time();
$nonce  = bin2hex(random_bytes(8));

$signStr = implode("\n", ['POST', $path, $ts, $nonce, hash_file('sha256', $file)]);
$sig     = hash_hmac('sha256', $signStr, $secret);

$ch = curl_init('https://你的域名' . $path);
curl_setopt_array($ch, [
    CURLOPT_POST       => true,
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_HTTPHEADER => ["X-App-Key: $key", "X-Timestamp: $ts",
                           "X-Nonce: $nonce", "X-Signature: $sig"],
    CURLOPT_POSTFIELDS => ['file' => new CURLFile($file)],
]);
echo curl_exec($ch);   // {"code":0,"data":{"url":"https://.../image/2026-09-12/1/xx.jpg"}}
