flask - something more strict than @api.expect for input data?

Question

In my flask-restplus API I\'d like not only to check that input data, like in the following example

resource_fields = api.model(\'Resource\', {
    \'name\': fie         


        

Answer 1

Instead of using a dictionary for your fields, try using a RequestParser (flask-restplus accepts both as documented here. That way, you can call parser.parse_args(strict=True) which will throw a 400 Bad Request exception if any unknown fields are present in your input data.

my_resource_parser = api.parser()
my_resource_parser.add_argument('name', type=str, default='string: name', required=True)
my_resource_parser.add_argument('state', type=str, default='string: state')

@api.route('/my-resource/')
class MyResource(Resource):
    def post(self):
        args = my_resource_parser.parse_args(strict=True)
        ...

For more guidance on how to use the request_parser with your resource, check out the ToDo example app in the flask-restplus repo.
