使用Tastypie api的jquery get方法的401 UNAUTHORIZED错误

Question

As of now I am not using authentication for Tastypie but I am able to see content, when I go to url in browser.

http://localhost:8000/live/api/update/?format=json

but I am trying to get this data in the page via an jquery ajax call,

$.post('/live/api/update/?format=json',
            {type:'GET',dataType: "json", processData:  false,
  contentType: "application/json",userid:$('#index').val()},function(devicelist){       
    .....       
    }

In browser firebug console, I m seeing a 401

Note : from Haris's Answer, I was able to solve the issue, but I want why it works

when I use

$.ajax({ type: "POST", url: url, data: data, success: success, dataType: dataType });

it is working(Status:202) whereas when I use

  $.post('/live/api/update/?format=json',
                {type:'GET',dataType: "json", processData:  false,
      contentType: "application/json",userid:$('#index').val()},function(devicelist){       
        .....       
        }

this is not working.Actually I shifted my PHP code to Django, when I used PHP the above code used to work with 401 error

There is no Authentication in tastypie api code

api.py

from tastypie.resources import ModelResource
from models import Update
from tastypie.serializers import Serializer
import urlparse

class urlencodeSerializer(Serializer):
    formats = ['json', 'jsonp', 'xml', 'yaml', 'html', 'plist', 'urlencode']
    ....


class UpdateResource(ModelResource):
    class Meta : 

        queryset = Update.objects.all()
        resource_name = 'update'
        filtering = {'imei' : ALL }
        #authentication = DjangoCookieBasicAuthentication()
        serializer = urlencodeSerializer() # IMPORTANT 
        allowed_methods = ['get','post']

Answer 1

you're sending a $.POST request with jquery, yet you're trying to change the type to a GET. Use .ajax if you want to add custom options to the ajax request.
