Customize transformers

Starlark is a dialect of Python intended for use as a configuration language.

The message transformer are written by Starlark language, and what you need to do is defining a transform function, modifying the incoming request accordingly, for example:

def transform(request):
    # print(requst["headers"])
    # print(requst["body"])
    msg_type = request["body"]["msg_type"]
    body = {}
    if msg_type == "text":
        body = {
            "msgtype": "text",
            "text": {"content": request["body"]["content"]["text"]},
        }
    request["body"] = body
    return request
