云点播token

Example

云点播token

php代码示例

$authKey='ucSzWPYPGydaT8mc';//Tk-authkey
$aes_key='abcdefghijklmnop';//机构自定义的16位字符串
$time=time();//Timestamp
$key = substr(openssl_digest(openssl_digest($authKey, 'sha1', true), 'sha1', true), 0, 16);
$keys = base64_encode(openssl_encrypt(strval($time), "AES-128-CBC", $key, OPENSSL_RAW_DATA, $aes_key));
$token = $aes_key . $keys;//生成Tk-token
var_dump(sprintf("Tk-authkey：%s", $authKey));
var_dump(sprintf("Timestamp：%s", $time));
var_dump(sprintf("Tk-token：%s", $token));
