I am wring an iPhone app that uploads an image to a blob via HTTP-
POST. Everything has been working great so far.
Recently, I decided to send a parameter "uuid" along with the image.
My python code on the server side (subclass of
blobstore_handlers.BlobstoreUploadHandler) receives this uuid (along
with the image) correctly as long as I run it under SDK, but fails to
receive the uuid when I deploy this app to the actual sever on
appspot.com. Is there any known issue with this additional parameter
to BlobstoreUploadHandler?
Here is my python code:
gdispatch.route(lambda: ('/blob/upload', UploadHandler))
class UploadHandler(blobstore_handlers.BlobstoreUploadHandler):
@gdispatch.kwargs
def post(self, uuid):
upload_files = self.get_uploads('file') # 'file' is file
upload field in the form
blob_info = upload_files[0]
logging.info("/blog/upload uuid=%s" % uuid)
...
gdispatch.kwargs is a decorator to make those parameters accessible as
arguments:
def kwargs(original_func):
""" This decorator allows RequestHandlers to receive get/post
parameters as named arguments """
import inspect
argspec = inspect.getargspec(original_func)
args = tuple(argspec[0][1:])
def decorated_func(rh):
kwargs = dict([(arg, rh.request.get(arg)) for arg in args])
return original_func(rh, **kwargs)
return decorated_func
Here is the actually data I am posting:
