Php 使用sha256 python使用base64编码计算hmac值

我正在尝试将php代码转换为python语言

php函数使用sha256和base64编码计算hmac值

我的Php函数：

<?php

define('SHOPIFY_APP_SECRET', 'some_key');

function verify_webhook($data)
{
$calculated_hmac = base64_encode(hash_hmac('sha256', $data, 
SHOPIFY_APP_SECRET, true));
echo $calculated_hmac;
}

$data = "some_data";
$verified = verify_webhook($data);
?>

import base64
import hmac
import binascii
from hashlib import sha256

API_SECRET_KEY = "some_key"
data = "some_data"

def verify_webhook():
    dig = hmac.new(
        API_SECRET_KEY,
        msg=data,
        digestmod=sha256
        ).digest()
    calculated_hmac = base64.b64encode(bytes(binascii.hexlify(dig)))
    print(calculated_hmac)

verify_webhook()

我得到了不同的输出，即使我有相同的密钥和数据。我还是不知道我错过了什么。请帮忙

Python输出：

<?php

define('SHOPIFY_APP_SECRET', 'some_key');

function verify_webhook($data)
{
$calculated_hmac = base64_encode(hash_hmac('sha256', $data, 
SHOPIFY_APP_SECRET, true));
echo $calculated_hmac;
}

$data = "some_data";
$verified = verify_webhook($data);
?>

import base64
import hmac
import binascii
from hashlib import sha256

API_SECRET_KEY = "some_key"
data = "some_data"

def verify_webhook():
    dig = hmac.new(
        API_SECRET_KEY,
        msg=data,
        digestmod=sha256
        ).digest()
    calculated_hmac = base64.b64encode(bytes(binascii.hexlify(dig)))
    print(calculated_hmac)

verify_webhook()

我能够使用Python 3匹配您的php输出：

>>> dig = hmac.new( bytes(API_SECRET_KEY,'ascii'), 
                    msg=bytes(data, 'ascii'), digestmod=sha256 )
>>> dig.digest()
b'7\xb2r\x03"\xa8r\x80\xf1\xfc\xeaq\xdf\xa9\xc6\xa8\x0b\x94)\xdc\x86\x1f\xe4N_\xe2y\x00\x98\x10\xfb\xf8'
>>> base64.b64encode(dig.digest())

伟大的它也适用于python2.7，我只将

字节（API\u SECRET\u KEY，'ascii'）

更改为

字节（API\u SECRET\u KEY）

。非常感谢你的帮助
