Why upload handler not match when using GAE blobstore

StackOverflow https://stackoverflow.com/questions/21200462

Domanda

I just follow GAE's document (https://developers.google.com/appengine/docs/python/blobstore/#Python_Uploading_a_blob) to write upload handler to upload blobstore, when I select one file on computer and click Submit button on HTML page, it will show 'The url "/upload" does not match any handlers.' Any comments is appreciated. 

class MainPage(webapp2.RequestHandler):
    def get(self):

        self.response.headers['Content-Type'] = 'text/html; charset=utf-8'

        upload_url = blobstore.create_upload_url('/upload')
        logging.info(upload_url)

        self.response.out.write('<html><body>')
        self.response.out.write('<form action="%s" method="POST" enctype="multipart/form-data">' % upload_url)
        self.response.out.write("""Upload File: <input type="file" name="file"><br> <input type="submit"
            name="submit" value="Submit"> </form></body></html>""")

class UploadHandler(blobstore_handlers.BlobstoreUploadHandler):

    def post(self):
        logging.info('Upload handler')
        upload_files = self.get_uploads('file')  # 'file' is file upload field in the form
        blob_info = upload_files[0]
        logging.info(upload_files)
        self.redirect('/serve/%s' % blob_info.key())


class ServeHandler(blobstore_handlers.BlobstoreDownloadHandler):

    def get(self, resource):
        resource = str(urllib.unquote(resource))
        logging.info(resource)
        blob_info = blobstore.BlobInfo.get(resource)
        self.send_blob(blob_info)


application = webapp2.WSGIApplication([
    ('/', MainPage),
    ('/upload', UploadHandler),
    ('/serve/([^/]+)?', ServeHandler),
], debug=True)

[Update1] After I click submit button, I check dev-server Blobstore Viewer, I found the file has been uploaded there, however, my chrome browser still show 'The url "/upload" does not match any handlers.'. This is why?

Soluzione

I want to ask my question by self that maybe someone encounter similar issue as me.

After I change from 

- url: /
  script: AppWS.application

to 

- url: (/.*)*
  script: AppWS.application

everything is OK.
