The AppEngine's standard API assumes files are uploaded from an HTML form. I'm trying to post a file to the blobstore from a REST API method that can be called by a non Html client (Flash, iPhone, etc.)
The code I'm trying to get working:
# Get the blobstore upload url
upload_url = blobstore.create_upload_url("/activities/upload_finished");
# Make sync call to the blobstore url to post our image
result = urlfetch.fetch(url=upload_url,
payload=request.FILES,
method=urlfetch.POST,
headers={'Content-Type': 'multipart/form-data'})
I'm getting the following error:
ValueError: Invalid boundary in
Any idea?
Has anyone tried posting to the blobstore not through a web form?
multipart form: ''
