Usage
create folder with your handlers TGHandlers/DefaultBotHandlers.swift
import Vapor
import TelegramVaporBot
final class DefaultBotHandlers {
static func addHandlers(app: Vapor.Application, connection: TGConnectionPrtcl) async {
await defaultHandler(app: app, connection: connection)
await commandPingHandler(app: app, connection: connection)
await commandShowButtonsHandler(app: app, connection: connection)
await buttonsActionHandler(app: app, connection: connection)
}
private static func defaultHandler(app: Vapor.Application, connection: TGConnectionPrtcl) async {
await connection.dispatcher.add(TGMessageHandler(filters: (.all && !.command.names(["/ping", "/show_buttons"]))) { update, bot in
let params: TGSendMessageParams = .init(chatId: .chat(update.message!.chat.id), text: "Success")
try await connection.bot.sendMessage(params: params)
})
}
private static func commandPingHandler(app: Vapor.Application, connection: TGConnectionPrtcl) async {
await connection.dispatcher.add(TGCommandHandler(commands: ["/ping"]) { update, bot in
try await update.message?.reply(text: "pong", bot: bot)
})
}
private static func commandShowButtonsHandler(app: Vapor.Application, connection: TGConnectionPrtcl) async {
await connection.dispatcher.add(TGCommandHandler(commands: ["/show_buttons"]) { update, bot in
guard let userId = update.message?.from?.id else { fatalError("user id not found") }
let buttons: [[TGInlineKeyboardButton]] = [
[.init(text: "Button 1", callbackData: "press 1"), .init(text: "Button 2", callbackData: "press 2")]
]
let keyboard: TGInlineKeyboardMarkup = .init(inlineKeyboard: buttons)
let params: TGSendMessageParams = .init(chatId: .chat(userId),
text: "Keyboard active",
replyMarkup: .inlineKeyboardMarkup(keyboard))
try await connection.bot.sendMessage(params: params)
})
}
private static func buttonsActionHandler(app: Vapor.Application, connection: TGConnectionPrtcl) async {
await connection.dispatcher.add(TGCallbackQueryHandler(pattern: "press 1") { update, bot in
let params: TGAnswerCallbackQueryParams = .init(callbackQueryId: update.callbackQuery?.id ?? "0",
text: update.callbackQuery?.data ?? "data not exist",
showAlert: nil,
url: nil,
cacheTime: nil)
try await bot.answerCallbackQuery(params: params)
})
await connection.dispatcher.add(TGCallbackQueryHandler(pattern: "press 2") { update, bot in
let params: TGAnswerCallbackQueryParams = .init(callbackQueryId: update.callbackQuery?.id ?? "0",
text: update.callbackQuery?.data ?? "data not exist",
showAlert: nil,
url: nil,
cacheTime: nil)
try await bot.answerCallbackQuery(params: params)
})
}
}vapor main.swift
make strong reference to TGBotConnection instance
import Vapor
import TelegramVaporBot
var TGBotConnection: TGConnectionPrtcl!
Use with LongPolling
for longpolling you should only configure vapor configure.swift
import TelegramVaporBot
public func configure(_ app: Application) throws {
let tgApi: String = "XXXXXXXXXX:YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY"
/// set level of debug if you needed
TGBot.log.logLevel = .info
let bot: TGBot = .init(app: app, botId: tgApi)
TGBotConnection = TGLongPollingConnection(bot: bot)
Task {
await DefaultBotHandlers.addHandlers(app: app, connection: TGBotConnection)
try await TGBotConnection.start()
}
try routes(app)
}
Use with Webhooks
vapor configure.swift
import TelegramVaporBot
public func configure(_ app: Application) throws {
let tgApi: String = "XXXXXXXXXX:YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY"
/// set level of debug if you needed
TGBot.log.logLevel = .info
let bot: TGBot = .init(app: app, botId: tgApi)
TGBotConnection = TGWebHookConnection(bot: bot, webHookURL: "https://your_domain/telegramWebHook")
Task {
await DefaultBotHandlers.addHandlers(app: app, connection: TGBotConnection)
try await TGBotConnection.start()
}
try routes(app)
}
vapor routes.swift
import Vapor
import TelegramVaporBot
func routes(_ app: Application) throws {
try app.register(collection: TelegramController())
}vapor TelegramController.swift
import Vapor
import TelegramVaporBot
final class TelegramController: RouteCollection {
func boot(routes: Vapor.RoutesBuilder) throws {
routes.get("telegramWebHook", use: telegramWebHook)
}
}
extension TelegramController {
func telegramWebHook(_ req: Request) async throws -> Bool {
let update: TGUpdate = try req.content.decode(TGUpdate.self)
try await TGBotConnection.dispatcher.process([update])
return true
}
}
