FAQ response with image url + header

ScienceGuy · January 4, 2022, 9:43am

Hello, I try to build an FAQ (retrieval intent) with responses containing images. It works well provided the image is publicly accessible via its url. However, I need to access images stored in a cloud storage and, therefore, I need to pass a header along with the URL. How would I do that?

My own guess would be to build a custom channel as the image seems to be handled there by the “send_image_url” method:

RasaHQ/rasa/blob/08bf76bd70cc58784556e69c60b03570149f1119/rasa/core/channels/channel.py#L259

    
      
          
          
async def send_text_message(
              self, recipient_id: Text, text: Text, **kwargs: Any
          ) -> None:
              """Send a message through this channel."""
          
          
    raise NotImplementedError(
                  "Output channel needs to implement a send message for simple texts."
              )
          
          
async def send_image_url(
              self, recipient_id: Text, image: Text, **kwargs: Any
          ) -> None:
              """Sends an image. Default will just post the url as a string."""
          
          
    await self.send_text_message(recipient_id, f"Image: {image}")
          
          
async def send_attachment(
              self, recipient_id: Text, attachment: Text, **kwargs: Any
          ) -> None:
              """Sends an attachment. Default will just post as a string."""
