Sending a Photo: not only from save-file? How to flow? #211

Closed ozett closed 2 years ago

ozett commented 3 years ago

on my flow an image is coming as base64 over MQTT. i always save that and asemmble the send-message with a save-file as content. are there other ways in node red to send that image without saving as a file?

How do i get the base64 image adressed in the content-option?

image

j-expression:

{
   "chatId": "-123456789",
   "type": "photo",
   "caption": "AI gesichtet: "  & msg.name & " (" & msg.confidence & "% )",
   "content": "/tmp/fm.jpg",
   "options": 
    {
       "disable_notification": "true"
    } 

}

you can use the buffer as content if it is a known format: e.g. Jpeg….

The send function checks if the content is a file_id, a url,or a buffer…. if it is a buffer then the media type is determined and then send right away …. Make sure that the buffer size does not exceed the limit and that the format is supported.

thanks for helping. fantastic. got it working with the func-node.

the last part is to reference msg.name in the function-node as part of the caption. (?) must be another secret syntax for me stupid low-coder... 😄 image

caption : „AI gesichtet: „ + msg.name + „ „ + msg.confidence,

gänsefüßchen natürlich oben…

Funktioniert das double-take?

ozett commented 3 years ago

ja, danke. 💐 auch noch so spät: Jsonata "&" -> javascript "+" exchanged the concatenation to javascript-style (and correct the typo 😄 )

🟢 caption: "AI gesichtet: " + msg.name + " (" + msg.confidence + "% )",

astrein, letzte beta! mit compreface bissl gefummel mit docker-compose. läuft jetzt bei mir paralell zu python und yolo, und kann für face-rec optimiert werden... spannend...
