Send the file

Unanswered

Sending and receiving messages is demonstrated numerous times in the BDK 2.0 courses. Please refer to the demos at the end of the chapters. Attachments are an optional field in the Message object, which accepts any type of InputStream. An example using FileInputStream would look like this:

// Java
Attachment file = new Attachment(new FileInputStream("./data.csv"), "data.csv");
Message msg = Message.builder().attachments(List.of(file)).content("Hello").build();
bdk.messages().send(streamId, msg);

# Python
with open("data.csv", "rb") as file:
  await bdk.messages().send_message(stream_id, Message(content="Hello", attachments=[file]))

Apologies - FileInputStream requires a second argument representing the displayed file name. I've revised the answer to reflect this.

        open("giphy.gif", "rb") as filePreview:
    message = Message(content="<messageML>Hello, World!</messageML>",
                      attachments=[(file1, filePreview)])
