how to upload muti file using html5 on google app engine(python)

this is my code, the upload.py:

class MyModel(db.Model):
    data = db.BlobProperty(required=True)
    mimetype = db.StringProperty(required=True)

class BaseRequestHandler(webapp.RequestHandler):
  def render_template(self, filename, template_args=None):
    if not template_args:
      template_args = {}
    path = os.path.join(os.path.dirname(__file__), 'templates', filename)
    self.response.out.write(template.render(path, template_args))

class upload(BaseRequestHandler):
  def get(self):
    self.render_template('index.html',)
  def post(self):
    file = self.request.POST['file']
    obj = MyModel(data=file.value, mimetype=file.type)
    obj.put()
    o=file
    #self.response.out.write(''.join('%s: %s <br/>' % (a, getattr(o, a)) for a in dir(o)))
    #return
    file_url = "http://%s/download/%d/%s" % (self.request.host, obj.key().id(), file.filename)
    self.response.out.write("Your uploaded file is now available at <a href='%s'>%s</a>" % (file_url,file_url,))

and the index.html is :

<form enctype="multipart/form-data" action="/" method="post">

You probably want to use the blobstore service for this; I wrote a series of posts (1, 2, 3) covering how to do multiple-file upload to the blobstore, using an upload widget.

AFAIK, the request.POST['file'] should be a dictionary of files, i.e. POST['file'] should have keys as names of the files uploaded and the value should be the contents of the files respectively, i.e. POST['file']['avatar.png'] = ... # raw image data.

I don't know what's the functionality provided by the GAE HTTP Request class, but it should be consistent to this. Whatever the case, it's definitely in self.request, somwhere!

EDIT:

Ok, I just noticed GAE creates a file object for you, my guessing is this should work:

for file in POST['file']:
    obj = MyModel(data=file.value, mimetype=file.type)
    obj.put()
