How to send string as a callback data (using Airgram as a bot)? about airgram HOT 7 CLOSED

According to schema.tl the data parameter have to be a byte's array:

keyboardButtonCallback#683a5e46 text:string data:bytes = KeyboardButton;

and

updateBotCallbackQuery#e73547e1 flags:# query_id:long user_id:int peer:Peer msg_id:int chat_instance:long data:flags.0?bytes game_short_name:flags.1?string = Update;

So if you want to use a string for the data parameter, you have to convert string to bytes and back. I created an example how to extend updates context with convertStringToBytes and convertBytesToString.

Ok. Got it. I prefer to use these functions without context:

export function convertBytesToString(airgram: Airgram, bytes: number[]): string {
  const createDeserializer = airgram.container.get<ag.MtpDeserializerFactory>(TYPES.MtpDeserializerFactory);
  const data = createDeserializer(bytes)
  return data.fetchString()
}

export function convertStringToBytes(airgram: Airgram, str: string): number[] {
  const createSerializer = airgram.container.get<ag.MtpSerializerFactory>(TYPES.MtpSerializerFactory);
  const data = createSerializer();
  data.storeString(str)
  return arrayBufferToBytes(data.getBuffer())
}

It works! Thanks!

One more question.
As an airgram bot I need to notify user that callback was accepted/handled.
In Teleram bot API I have answerInlineQuery.
What request must I send to achieve the same result in airgram?

@esindger Can you help me in my question?

from airgram.

Method answerInlineQuery is not a part of schema.tl, this opportunity available only in the Bot API. Unfortunately, I couldn't find an analogue but in the docs of other mtproto client there is a mention of the method. You may try to send request Airgram.client.callApi<any, any>("answerInlineQuery", PARAMS). Probably it will work.

from airgram.

It wont work because answerInlineQuery is not in the schema and can not be serialized.

Got it, thanks!
It's a pity... I was thinking to completely replace Telegram bot API with MTProto and your awesome library!
