I have started with pyjamas that use JSON RPC and would like to use
"JSON RPC views" but found only external libraries solution. I have
written following snippets and wonder if they could be added to
django.utils:
class JsonResponse(HttpResponse):
"""
Http response which has JSON content.
"""
mimetype = 'application/json; charset=utf8'
def __init__(self, data):
content = simplejson.dumps(data, indent=2, ensure_ascii=False)
super(JsonResponse, self).__init__(content=content,
mimetype=self.mimetype)
class JsonRPCService(object):
"""
Class that implement a JSON RPC service. The RPC methods are
members methods of a successor which must implement them.
Usage:
- create instance of the successor implementing desired methods
- add its dispatch method among your urls
"""
version = '2.0'
@csrf_exempt
def dispatch(self, request):
try:
data = simplejson.loads(request.raw_post_data)
ver = data['jsonrpc']
if ver != self.version:
raise Exception('incorrect JSON RPC version')
methodName = data['method']
messId = data['id']
params = data['params']
method = getattr(self, methodName)
response = method(*params)
response = {"result": response, "error": None, "id": messId}
except Exception, e:
response = {"result": None, "error": e.message, "id": messId}
return JsonResponse(response)
class SampleJSONService(JsonRPCService):
def echo(self, data):
return data
