Media Echo Bot¶

A bot that receives all message types -- text, images, voice, files, and videos -- and echoes them back. Media messages are downloaded and re-sent.

See examples/media_echo.py in the repository.

Usage¶

pip install weilink[media]
python examples/media_echo.py

Set the log level with the LOGLEVEL environment variable (default: INFO):

LOGLEVEL=DEBUG python examples/media_echo.py

How It Works¶

1. Logs in and enters the receive loop.

2. Dispatches each incoming message by its msg_type:

   • TEXT -- replies with "Echo: <text>".
   • IMAGE -- downloads the image with wl.download(msg), then re-sends it with wl.send(user, image=data).
   • VOICE -- downloads the voice clip. If a transcription is available (msg.voice.text), replies with the transcript; otherwise re-sends the audio.
   • FILE -- downloads the file and re-sends it, preserving the original filename.
   • VIDEO -- downloads the video and re-sends it.

3. All media errors are caught and reported back to the user as text.

Key Features Demonstrated¶

• MessageType enum -- branching on MessageType.TEXT, IMAGE, VOICE, FILE, VIDEO.
• Media download -- wl.download(msg) returns raw bytes.
• Sending media -- wl.send() accepts image, voice, file, video keyword arguments.
• File metadata -- accessing msg.file.file_name, msg.image.thumb_width, msg.voice.playtime, etc.
