我正在尝试将 Google Checkout 集成到我的网站中。我创建了以下函数来生成所需的 hmac-sha-1 签名:
def make_signature(cart_xml):
import hmac
import hashlib
import base64
# The number is a psuedo-merchantID, cart_xml contains a string with the
# shopping cart xml as outlined on google's documentation.
signature = hmac.new("711348421531236", cart_xml, hashlib.sha1)
signature = base64.b64encode(signature.digest())
return signature
但是,我无法让我的购物车验证签名。我不断收到以下错误:“购物车签名错误”
有谁知道如何解决这一问题?
