"""Handle a JSON-based API call.
This function is called when Django is about to call a view. It will
decode a POST body in JSON format, call the view, and encode the
response in JSON format.
The request should be a POST with a Content-Type of "application/json".
The body of the request should be a JSON-encoded list of arguments to
pass to the API call. The arguments will be unpacked and passed in as
positional and keyword arguments to the view function as described
below. If the view function returns data, it will be JSON-encoded and
sent back as a response with Content-Type "application/json". If the
view function returns an HttpResponse object, this will be sent back
to the client as is.
The request body can specify API calls in one of two ways, the old
style or the new style. In the old style, only positional arguments
may be passed, and the request body is simply a list of positional
arguments. In the new style, both positional and keyword arguments may
be passed, and the request body is a dict with 'args' and 'kwargs'
entries.
Old style: ['arg1', 'arg2']
New style: {
'args': ['arg1', 'arg2'],
'kwargs': {'arg3': 'value3, 'arg4': 'value4'}
}
Arguments:
request -- The HttpRequest object from Django.
view -- The view function that Django is about to call.
view_args -- The position arguments Django would pass to the view.
view_kwargs -- The keyword arguments Django would pass to the view.
Status Codes Returned:
200 -- The request was completed successfully.
405 -- A method other than POST was used.
415 -- A request body type other than application/json was sent.
500 -- The view function raised an unhandled exception, or returned
unserializable data (see exception value for details).
? -- View functions may return whatever HTTP status codes they
deem appropriate. See the documentation for each view function.
