NodeJS HMAC哈希创建

Question

I am trying to follow part of a tutorial for an API written in PHP. They show the following example:

$public = 'JkAFq7M47kLN0xVD';
$private = 'E6X9FyZvMFeJbqtq.IwjlTuR.MKDoicB';

$url = 'https://pterodactyl.local/api/admin/users';
$body = '';

$hmac = hash_hmac('sha256', $url . $body, $private, true);

return $public . '.' . base64_encode($hmac);

// Should return the string below:
//
// JkAFq7M47kLN0xVD.wgIxj+V8RHgIetcQg2lRM0PRSH/y5M21cPz9zVhfFaQ=

But my method doesn't return the proper value. Instead it returns the following:

JkAFq7M47kLN0xVD./RKZS3U2FKfEt7/tEks4vWwyS+89lL+k8aEGO8NJWuo=

Here is my code:

    hmac = crypto.createHmac('sha256', private_key);
    hmac.write(url+body);
    hmac.end();
    hash = hmac.read().toString('base64');
    console.log(hash);

EDIT: I think the example they provided was invalid because as everyone is saying my code is almost identical and the PHP code outputs a different value then it said it should in the documentation.

Answer 1

ok so, i used this tool writephponline to run this php code:

$public = 'JkAFq7M47kLN0xVD';
$private = 'E6X9FyZvMFeJbqtq.IwjlTuR.MKDoicB';

$url = 'https://pterodactyl.local/api/admin/users';
$body = '';

$hmac = hash_hmac('sha256', $url . $body, $private, true);

echo $public . '.' . base64_encode($hmac);

and returns:

JkAFq7M47kLN0xVD./RKZS3U2FKfEt7/tEks4vWwyS+89lL+k8aEGO8NJWuo=

So i used that as a parameter, then i made a little nodejs script:

var crypto = require('crypto');

var public = 'JkAFq7M47kLN0xVD';

var private = 'E6X9FyZvMFeJbqtq.IwjlTuR.MKDoicB';

var url = 'https://pterodactyl.local/api/admin/users';

var body = '';

var hmac = crypto.createHmac('sha256', private).update(url+body).digest('base64');

console.log(public + '.' + hmac);

and returns:

JkAFq7M47kLN0xVD./RKZS3U2FKfEt7/tEks4vWwyS+89lL+k8aEGO8NJWuo=

Hope it helps.
