Don’t know if it’s I’m doing it wrong or if there’s a bug (I would think so, seen others having the same problem) in the blobstore.create_upload_url method.

In my app.yaml I have for some url’s the property secure: always and the action attribute of the form element starts with https:// but when it’s return from the API it’s redirected to non-https.

There’s a bug file on google app engine issue tracker but no response from google.

Does anyone know of a good work around? My current solution is to have a separate .py file to handle the response and then direct back to the original url but over https.

EDIT

I use this to set the action attribute:

from google.appengine.api import blobstore
view['upload_url'] = blobstore.create_upload_url 
## pass the view dict to template and in template

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

The output in the html looks something like:

action="https://appid.appspot.com/_ah/upload/AMmfu6bcA9Sfz5isqw6PNNB8xzRy2rUoLaMS2GFjfPEwCZ-vg9M_hQTOR87wYdnMo7ZIbQX9NiNjORFTiKaUoLMHRpXvPf6r8Y5963GD9Cbv_9gIKgtEmtdvt5VcvQxzvbegqG3V5xQT/ALBNUaYAAAAATPdfcxxACFrQnUiLXWx61ViMDZ7F0aLF/"

The file uploads (I can view it in admin console->blob viewer) but when the API redirect back it redirects http and when using secure: always a http request returns a HTTP 405 error.

This is the upload handler:

class AddUpdateImageStore(blobstore_handlers.BlobstoreUploadHandler):
def post(self):
    if self.request.get('imagestore_key'):
        image = dbImageStore.ImageStore.get(self.request.get('imagestore_key'))
    else:
        image = dbImageStore.ImageStore()

    image.name = self.request.get('image_name')

    upload_files =  self.get_uploads('image_file')

    if upload_files:
        image.imageUrl = images.get_serving_url(str(upload_files[0].key()))

    imageKey = db.put(image)

    for language in Settings.languages:
        description = self.request.get('image_description_' + language)
        if description:
            imageDescription = dbImageStore.ImageDescription.gql('WHERE imageEntry = :imageEntry AND lang = :lang', imageEntry = imageKey, lang = language).get()
            if imageDescription is None:
                imageDescription = dbImageStore.ImageDescription()
                imageDescription.imageEntry = imageKey
                imageDescription.lang = language

            imageDescription.description = description
            db.put(imageDescription)

    self.redirect('/edit/imageStore/?status=1&message=Image added/updated')
