如何生成WM_SEC.AUTH_SIGNATURE？

有谁有可以为 Walmart API 生成此标头的 python 代码吗？

WM_SEC.AUTH_SIGNATURE

我试图理解 java 示例，但我没有任何运气，因为我没有 Java 经验。

如果有人知道需要签名的字符串的格式，我可能可以从那里弄清楚。

我该如何解决这个问题？

这是我最终用来获取工作授权（如果有人需要的话）的代码：

import requests, json, pprint, time
from requests.auth import HTTPBasicAuth
import errno
from Crypto.Hash import SHA256
from Crypto.PublicKey import RSA
from Crypto.Signature import PKCS1_v1_5
import hashlib
import base64


ACCOUNT_SID = 'xxxxxx'
AUTH_TOKEN = 'xxxxxxxx'
BASE_URL = 'https://products.api.impactradius.com/Mediapartners/{}/'.format(ACCOUNT_SID)
API_PATH = 'Catalogs/4277'
consumerId = 'xxxxxxxx'
epoxTime = str(int(time.time()*1000))
keyVersion = '1'

URL = 'https://developer.api.walmart.com/api-proxy/service/affil/product/v2/items'


hashDict = { 'WM_CONSUMER.ID' : consumerId,
            'WM_CONSUMER.INTIMESTAMP' : epoxTime,
            'WM_SEC.KEY_VERSION' : keyVersion
            }
sortedHashString = hashDict['WM_CONSUMER.ID'] +'\n'+ hashDict['WM_CONSUMER.INTIMESTAMP'] +'\n'+ hashDict['WM_SEC.KEY_VERSION']+'\n'
encodedHashString = sortedHashString.encode()

try:
    with open('./WM_IO_private_key.pem', 'r') as f:
        key = RSA.importKey(f.read())
except IOError as e:
    print(e)

hasher = SHA256.new(encodedHashString)
signer = PKCS1_v1_5.new(key)
signature = signer.sign(hasher)

signature_enc = str(base64.b64encode(signature),'utf-8')

headers = { 'WM_CONSUMER.ID' : consumerId,
            'WM_CONSUMER.INTIMESTAMP' : epoxTime,
            'WM_SEC.AUTH_SIGNATURE' : signature_enc,
            'WM_SEC.KEY_VERSION' : keyVersion,
            'WM_QOS.CORRELATION_ID' : 'afjksldkfj4r8ojfns',
            'WM_IFX.CLIENT_TYPE' : 'INTERNAL',
            'WM_PREVIEW' : 'false',
            'WM_SHOW_REASON_CODES' : 'ALL',
            'Content-Type' : 'application/json',
            }

params = {
            'category' : '4171_1228385',
            'publisherId' : 'xxxxxxxxxxx'
        }

response = requests.get(URL, headers=headers, params=params)

jsonData = json.loads(response.text)
