Django simplejson error

I'm attempting to use simplejson to parse a JSON string. For some reason, when I use simplejson.loads I recieve 开发者_如何学编程the following error:

ERROR:root:Exception in request:

JSONDecodeError: No JSON object could be decoded: line 1 column 0 (char 0)
INFO:root:"POST /entry_ajax/ HTTP/1.1" 500 -

The JSON string is being generated by the native javscript JSON.stringify function and is as follows:

{'type':'basic','id':'156','payload':{'text':'asd'}}

The following is the code of the view:

    def entry_ajax(request):
        entry_param = str(request.POST)
        test = simplejson.loads(entry_param)
        return HttpResponse(test['type'])  

Any thoughts?

This is not a valid JSON string. Use double quotes:

{"type":"basic","id":"156","payload":{"text":"asd"}}
