Python w / Stripe：如何从收费响应中获取有效的JSON？

Question

I have a python wrapper method called succeed that looks like the following:

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))

I am trying to pass the result of a Stripe API call to charge a credit card back to another service using this method. Here is the method call, inside of another class:

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

When I do so, I get a 'charge is not JSON serializable' error. How can I pass all of the charge ID responses along as JSON with this code? Here is the full response:

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

  "captured": true,

Answer 1

Use the .to_dict() method to turn a Stripe charge object into a python dictionary.

Serializing a dict is an exercise left to the reader.

As an additional fun point, I highly suggest the dir function: It lets you see all the possible attributes and methods.

For example:

>>> 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']
>>>

From here you can see the to_dict method. You can also see the serialize method, though it's not clear to me what it does.

Answer 2

Though its late, the following answer may help someone

As per the stripe team to_dict method is deprecated. See here

Since the Stripe object is the inheritance of dict , we can use them as native data type.

Also calling str("Stripe Object") will return JSON representation of the object. See here
