1.下载官方SDK，文档上有地址
2.下载的SDK引入会报错，缺少类Monolog/Logger，需要用SDK中composer加载，然后放入SDK中
3.我用的tp5.1框架，SDK放到了项目vendor目录下，方法中需要引入SDK中三个类文件,具体代码：
public function test(){
header("Content-type: text/html; charset=utf-8");
vendor('JD_DECRYPT_SDK.vendor.autoload');//这里的vendor是composer加载的文件
vendor("JD_DECRYPT_SDK.security.SecretJdClient");
vendor("JD_DECRYPT_SDK.security.TDEClient");
//$this->accessToken是accessToken , $this->appKey是appKey , $this->appSecret是appSercret
$tde = \ACES\SecretJdClient::getInstance($this->accessToken, $this->appKey, $this->appSecret);
//加密方法encrypt
// $ct = $tde->encrypt($pt);
// echo $ct;
$ct = 'AATdzwjhRcQuGgpzE0j+XhVquJ1g0k6/uL9SjrgaJ/wnro6JGAKzLQquLhyk3QRgtTg=';
//解密方法decrypt
$decrypted = $tde->decrypt($ct);
return $decrypted;
}
