django上传图片

# coding=utf-8
import StringIO
from PIL import Image

from django.http import HttpResponse
from django.shortcuts import render_to_response

UPLOAD_URL = 'photo/upload/'

def upload(request):
    buf = request.FILES.get('photo', None)
    data = buf.read()
    f = StringIO.StringIO(data)
    image = Image.open(f)
    image = image.convert('RGB')
    name = '%s%s' % (UPLOAD_URL, buf.name)
    image.save(file(name, 'wb'), 'PNG')
    return HttpResponse('成功')

网上有写资料用buf['content']代替buf.read()，buf['filename']代替buf.name这样会出现异常
