Python w/Stripe:如何从收费响应中获取有效的JSON？

Question

我有一个名为python包装器的方法succeed,如下所示:

def succeed(handler, data):
"""Send the given |data| dict as a JSON response in |handler.response|."""
set_headers(handler)
handler.response.write(json.dumps(data))

我试图传递Stripe API调用的结果,使用此方法将信用卡收回另一个服务.这是方法调用,在另一个类中:

succeed(self, dict(success=True, charge_id=charge.id, response=charge))

当我这样做时,我得到'充电不是JSON可序列化'错误.如何使用此代码将所有费用ID响应作为JSON传递？以下是完整的回复:

    TypeError: <Charge charge id=ch_103Tsv2kD9PLZlzDG5ce7TE1 at 0x113003b50> JSON: {
  "amount": 3500, 
  "amount_refunded": 0,

}

使用该.to_dict()方法将条带充电对象转换为python字典.

序列化词典是留给读者的练习.

作为一个额外的有趣点,我强烈建议使用dir它:它可以让你看到所有可能的属性和方法.

例如:

>>> import stripe
>>> dir(stripe.Charge)
['__class__', '__cmp__', '__contains__', '__delattr__', '__delitem__', '__dict__', '__doc__', '__eq__', '__format__', '__ge__', '__getattr__', '__getattribute__', '__getitem__', '__gt__', '__hash__', '__init__', '__iter__', '__le__', '__len__', '__lt__', '__module__', '__ne__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__setitem__', '__sizeof__', '__str__', '__subclasshook__', '__weakref__', 'all', 'capture', 'class_name', 'class_url', 'clear', 'close_dispute', 'construct_from', 'copy', 'create', 'fromkeys', 'get', 'has_key', 'instance_url', 'items', 'iteritems', 'iterkeys', 'itervalues', 'keys', 'pop', 'popitem', 'refresh', 'refresh_from', 'refund', 'request', 'retrieve', 'save', 'serialize', 'serialize_metadata', 'setdefault', 'stripe_id', 'to_dict', 'update', 'update_dispute', 'values', 'viewitems', 'viewkeys', 'viewvalues']
>>>

从这里你可以看到to_dict方法.您也可以看到该serialize方法,但我不清楚它的作用.
