Telegram Bot Server by Vapor

This is a demo of how to create a telegram robot server using swift-telegram-bot-api. This demo created by vapor. If you need to use telegram's webhook feature, you will need to deploy this service on the server and use https. Of course you can also use long polling to get the latest news.

Example

import Vapor
import TelegramBotAPI

class EchoBotController: TelegramBotController {

    override func boot(router: Router) throws {
        try super.boot(router: router)
        router.get(name, token, String.parameter, String.parameter, use: self.quickSend)
    }
    

    /// GET  /:name/:token/:id/:message
    func quickSend(_ req: Request) throws -> Future<TelegramModel<TelegramAPI.Message>> {
        let chatId = try req.parameters.next(String.self)
        let text = try req.parameters.next(String.self)
        let tgReq = TelegramAPI.sendMessage(chatId: TelegramAPI.ChatId(chatId), text: text.removingPercentEncoding ?? text)
        return try req.sendTelegramRequest(tgReq, token: token)
    }

    override func handleWebhookMessage(_ message: TelegramAPI.Message, at worker: Container) throws -> EventLoopFuture<HookResponse> {
        print("\(message.from?.username ?? "UnknowUser") -> \(message.chat.id) -> \(message.text ?? "")")
        let text = "Re: \(message.text ?? "")"
        let tgReq = TelegramAPI.sendMessage(chatId: TelegramAPI.ChatId(message.chat.id), text: text)
        let msg: Future<TelegramModel<TelegramAPI.Message>> = try worker.sendTelegramRequest(tgReq, token: token)
        return msg.map({ HookResponse($0)})
    }   
}
