Custom JSONEncoder for requests.post

Question

I'm writing wrapper for REST API and use requests module.

Method .json() of Response object transfers **kwargs to json.loads() function, so I can easily use custom JSON decoder and, i. e. transparently convert UNIX epoch timestamps to datetime.datetime objects.

Is there any way to use custom JSON encoder with Request object? Seems I can only use parameter json, but can't find how to use custom JSON encoder with it.

Answer 1

Extracting the answer from the link provided by alecxe, using a custom encoder and the json parameter is not supported. It's recommended you just construct the post manually.

r = requests.post('http://foo.bar',
              data=json.dumps(some_data, cls=CustomJSONEncoder),
              headers={'Content-Type': 'application/json'})
