在ionic4打字稿中实现AES

Question

我很了解php，但不了解ts 我在php的服务器中有一个代码

header("Access-Control-Allow-Origin: *");
define('AES_256_CBC', 'aes-256-cbc');
$encryption_key = ".........";

$iv = ".........";      
$encrypted= str_replace( " " ,"+",$_GET['data'] );

$encrypted = $encrypted . ':' . base64_encode($iv);

$parts = explode(':', $encrypted);

$decrypted = openssl_decrypt($parts[0], AES_256_CBC, $encryption_key, 0, base64_decode($parts[1]));

我如何在打字稿中使用它？
