如何从python GAE中的PayPal沙箱上线？

Question

我可以run and test my application in sandbox mod使用google app engine example provided by paypal。现在，我想启用实时模式，以便在沙箱模式工作时测试真实付款。我在www.x.com上注册了PayPal应用程序，并填写了以下详细信息：

我的商家设置如下：

这些设置看起来可以在实时模式下工作但似乎我有一些设置错误，因为我在尝试激活实时模式时收到错误消息：

可能相关的代码部分是

  def paykey( self ):
    return self.response['payKey']

当然这没什么用，所以我应该在哪里看？当我将其更改为以下内容时，我的settings.py是否正确：

# settings for app

#PAYPAL_ENDPOINT = 'https://svcs.sandbox.paypal.com/AdaptivePayments/' # sandbox
PAYPAL_ENDPOINT = 'https://svcs.paypal.com/AdaptivePayments/' # production

# EMBEDDED_ENDPOINT = 'https://paypal.com/webapps/adaptivepayment/flow/pay'
EMBEDDED_ENDPOINT = 'https://www.sandbox.paypal.com/webapps/adaptivepayment/flow/pay'

API_ID = '8byQd46LwexZ'
TRANSACTION_KEY = '3a578UZJXnh6Aa25'

我的错误消息可能来自哪个其他想法？

无法获得payKey。这会失败，因为您使用了错误的凭据：

PAYPAL_USERID = 'niklasro@gmail.com'#'niklas_1224389428_biz_api1.eddaconsult.se' PAYPAL_PASSWORD = '<my-paypal-password>'#'13344842639'

将其更改为使用您的API用户名和API密码。
