Un ejemplo de uso de una biblioteca Java para crear un bot de Telegram

Todos los desarrolladores (y no solo) que usan Telegram en la vida cotidiana, al menos una vez pensaron en cómo se siente crear su propio bot, lo difícil que es y qué lenguaje de programación es mejor usar.


Puedo dar la respuesta más simple (y probablemente la más correcta) a todas estas preguntas: todo depende de usted, su conocimiento e intenciones.


... Pero en este breve artículo, le mostraré cómo puede crear su propio bot en Java y que es bastante interesante y sin complicaciones.


Utilizaremos la biblioteca para trabajar con la API de Telegram Bots y su extensión , lo que nos permite crear nuestros propios comandos (' /custom_cmd ') y procesarlos de una manera simple.


La tarea del bot será registrar al usuario y enviar un mensaje desde el nombre especificado a otros usuarios del bot.


Creación de un nuevo proyecto y preparación.


1. Agregar dependencias al proyecto


Cree un nuevo proyecto maven y edite pom.xml , agregando las dependencias necesarias:


pom.xml
  <?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>io.example</groupId> <artifactId>anonymizerbot</artifactId> <version>1.0-SNAPSHOT</version> <build> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <configuration> ```8</source> <target>8</target> </configuration> </plugin> </plugins> </build> <dependencies> <!-- Telegram API --> <dependency> <groupId>org.telegram</groupId> <artifactId>telegrambots</artifactId> <version>LATEST</version> </dependency> <dependency> <groupId>org.telegram</groupId> <artifactId>telegrambotsextensions</artifactId> <version>LATEST</version> </dependency> ... </dependencies> </project>

Telegram API: una biblioteca para trabajar con la API de Telegram Bots , contiene clases y métodos para interactuar con los servicios de Telegram y algunas extensiones de estas clases.


2. Crear una cuenta para el bot


Para hacer esto, necesitamos contactar al bot BotFather para obtener ayuda:


  • encuentra el bot en la búsqueda;
  • ejecuta el comando "/ start";
  • ejecuta el comando "/ newbot";
  • establezcamos un nombre para nuestro bot (debería terminar con "Bot"). Lo llamé "ExampleOfAnonymizerBot".

Después de ejecutar estos comandos, obtendremos el token que necesitamos para usar la API Bot. (7xxxxxxx2: Axxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx0)






Implementación


1. Modelo de remitente anónimo de mensajes


Los datos que necesitamos de cada usuario:


  • Usuario mUsuario: información sobre el usuario de Telegram;
  • Chat mChat: información de chat de usuario y bot;
  • String mDisplayedName: el nombre desde el cual el usuario enviará mensajes a otros usuarios del bot.

Anonymous.java
 package io.example.anonymizerbot.model; import org.apache.logging.log4j.LogManager; import org.apache.logging.log4j.Logger; import org.telegram.telegrambots.meta.api.objects.Chat; import org.telegram.telegrambots.meta.api.objects.User; public final class Anonymous { private static final Logger LOG = LogManager.getLogger(Anonymous.class); private static final String USER_CHAT_CANNOT_BE_NULL = "User or chat cannot be null!"; private final User mUser; private final Chat mChat; private String mDisplayedName; public Anonymous(User user, Chat chat) { if (user == null || chat == null) { LOG.error(USER_CHAT_CANNOT_BE_NULL); throw new IllegalStateException(USER_CHAT_CANNOT_BE_NULL); } mUser = user; mChat = chat; } @Override public int hashCode() { return mUser.hashCode(); } @Override public boolean equals(Object obj) { return obj instanceof Anonymous && ((Anonymous) obj).getUser().equals(mUser); } public User getUser() { return mUser; } public Chat getChat() { return mChat; } public String getDisplayedName() { return mDisplayedName; } public void setDisplayedName(String displayedName) { mDisplayedName = displayedName; } }

Agregue un servicio que contenga métodos comúnmente utilizados para manipular muchos usuarios anónimos.


AnonymousService.java
 package io.example.anonymizerbot.service; import io.example.anonymizerbot.model.Anonymous; import org.telegram.telegrambots.meta.api.objects.User; import java.util.HashSet; import java.util.Objects; import java.util.Set; import java.util.stream.Stream; public final class AnonymousService { private final Set<Anonymous> mAnonymouses; public AnonymousService() { mAnonymouses = new HashSet<>(); } public boolean setUserDisplayedName(User user, String name) { if (!isDisplayedNameTaken(name)) { mAnonymouses.stream().filter(a -> a.getUser().equals(user)).forEach(a -> a.setDisplayedName(name)); return true; } return false; } public boolean removeAnonymous(User user) { return mAnonymouses.removeIf(a -> a.getUser().equals(user)); } public boolean addAnonymous(Anonymous anonymous) { return mAnonymouses.add(anonymous); } public boolean hasAnonymous(User user) { return mAnonymouses.stream().anyMatch(a -> a.getUser().equals(user)); } public String getDisplayedName(User user) { Anonymous anonymous = mAnonymouses.stream().filter(a -> a.getUser().equals(user)).findFirst().orElse(null); if (anonymous == null) { return null; } return anonymous.getDisplayedName(); } public Stream<Anonymous> anonymouses() { return mAnonymouses.stream(); } private boolean isDisplayedNameTaken(String name) { return mAnonymouses.stream().anyMatch(a -> Objects.equals(a.getDisplayedName(), name)); } }

2. Interfaz bot


Cualquier comando personalizado debe heredar de BotCommand e implementar un método
execute(AbsSender sender, User user, Chat chat, String[] strings) , que se utiliza para procesar los comandos del usuario.


Después de procesar el comando del usuario, podemos enviarle una respuesta utilizando el método de execute de la clase AbsSender , que toma la execute(AbsSender sender, User user, Chat chat, String[] strings) mencionada anteriormente execute(AbsSender sender, User user, Chat chat, String[] strings) .


En lo sucesivo, para no ajustar cada vez el método de AbsSender.execute , que puede lanzar una AbsSender.execute TelegramApiException , en try-catch , y para no escribir registros monótonos en cada comando, crearemos la clase AnonymizerCommand y AnonymizerCommand nuestros comandos personalizados. (dejaremos el manejo de excepciones en este ejemplo):


AnonymizerCommand.java
 package io.example.anonymizerbot.command; import io.example.anonymizerbot.logger.LogLevel; import io.example.anonymizerbot.logger.LogTemplate; import org.apache.logging.log4j.Level; import org.apache.logging.log4j.Logger; import org.apache.logging.log4j.LogManager; import org.telegram.telegrambots.extensions.bots.commandbot.commands.BotCommand; import org.telegram.telegrambots.meta.api.methods.send.SendMessage; import org.telegram.telegrambots.meta.api.objects.User; import org.telegram.telegrambots.meta.bots.AbsSender; import org.telegram.telegrambots.meta.exceptions.TelegramApiException; abstract class AnonymizerCommand extends BotCommand { final Logger log = LogManager.getLogger(getClass()); AnonymizerCommand(String commandIdentifier, String description) { super(commandIdentifier, description); } void execute(AbsSender sender, SendMessage message, User user) { try { sender.execute(message); log.log(Level.getLevel(LogLevel.SUCCESS.getValue()), LogTemplate.COMMAND_SUCCESS.getTemplate(), user.getId(), getCommandIdentifier()); } catch (TelegramApiException e) { log.error(LogTemplate.COMMAND_EXCEPTION.getTemplate(), user.getId(), getCommandIdentifier(), e); } } }

Defina los comandos a los que responderá nuestro bot:


  • /start : crea un nuevo Anonymous sin nombre y agrégalo a la colección Anonymouses ;

StartCommand.java
 package io.example.anonymizerbot.command; import io.example.anonymizerbot.logger.LogLevel; import io.example.anonymizerbot.logger.LogTemplate; import io.example.anonymizerbot.model.Anonymous; import io.example.anonymizerbot.service.AnonymousService; import org.apache.logging.log4j.Level; import org.telegram.telegrambots.meta.api.methods.send.SendMessage; import org.telegram.telegrambots.meta.api.objects.Chat; import org.telegram.telegrambots.meta.api.objects.User; import org.telegram.telegrambots.meta.bots.AbsSender; public final class StartCommand extends AnonymizerCommand { private final AnonymousService mAnonymouses; //     , //        public StartCommand(AnonymousService anonymouses) { super("start", "start using bot\n"); mAnonymouses = anonymouses; } /** *    BotCommand,    ,   * @param absSender -    * @param user - ,    * @param chat -     * @param strings - ,    */ @Override public void execute(AbsSender absSender, User user, Chat chat, String[] strings) { log.info(LogTemplate.COMMAND_PROCESSING.getTemplate(), user.getId(), getCommandIdentifier()); StringBuilder sb = new StringBuilder(); SendMessage message = new SendMessage(); message.setChatId(chat.getId().toString()); if (mAnonymouses.addAnonymous(new Anonymous(user, chat))) { log.info("User {} is trying to execute '{}' the first time. Added to users' list.", user.getId(), getCommandIdentifier()); sb.append("Hi, ").append(user.getUserName()).append("! You've been added to bot users' list!\n") .append("Please execute command:\n'/set_name <displayed_name>'\nwhere &lt;displayed_name&gt; is the name you want to use to hide your real name."); } else { log.log(Level.getLevel(LogLevel.STRANGE.getValue()), "User {} has already executed '{}'. Is he trying to do it one more time?", user.getId(), getCommandIdentifier()); sb.append("You've already started bot! You can send messages if you set your name (/set_name)."); } message.setText(sb.toString()); execute(absSender, message, user); } }

  • /help : muestra información sobre todos los comandos disponibles para el usuario (el constructor difiere de los demás en que necesita pasarle ICommandRegistry , que contiene todos los comandos personalizados);

3. Inicialización y lanzamiento del bot.


Una clase de bot en la que se registran todos los comandos personalizados, un controlador de mensajes de no comandos y comandos desconocidos.


AnonymizerBot.java
 package io.example.anonymizerbot.bot; import io.example.anonymizerbot.command.*; import io.example.anonymizerbot.logger.LogLevel; import io.example.anonymizerbot.logger.LogTemplate; import io.example.anonymizerbot.model.Anonymous; import io.example.anonymizerbot.service.AnonymousService; import org.apache.logging.log4j.Level; import org.apache.logging.log4j.LogManager; import org.apache.logging.log4j.Logger; import org.telegram.telegrambots.bots.DefaultBotOptions; import org.telegram.telegrambots.extensions.bots.commandbot.TelegramLongPollingCommandBot; import org.telegram.telegrambots.meta.api.methods.send.SendMessage; import org.telegram.telegrambots.meta.api.objects.Message; import org.telegram.telegrambots.meta.api.objects.Update; import org.telegram.telegrambots.meta.api.objects.User; import org.telegram.telegrambots.meta.exceptions.TelegramApiException; import java.util.stream.Stream; public final class AnonymizerBot extends TelegramLongPollingCommandBot { private static final Logger LOG = LogManager.getLogger(AnonymizerBot.class); //  ,        BotFather //  ,     private static final String BOT_NAME = "AnonymizerBotExample"; private static final String BOT_TOKEN = "7xxxxxxx2:Axxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx0"; private final AnonymousService mAnonymouses; public AnonymizerBot(DefaultBotOptions botOptions) { super(botOptions, BOT_NAME); LOG.info("Initializing Anonymizer Bot..."); LOG.info("Initializing anonymouses list..."); mAnonymouses = new AnonymousService(); //     LOG.info("Registering commands..."); LOG.info("Registering '/start'..."); register(new StartCommand( mAnonymouses)); LOG.info("Registering '/set_name'..."); register(new SetNameCommand(mAnonymouses)); LOG.info("Registering '/stop'..."); register(new StopCommand(mAnonymouses)); LOG.info("Registering '/my_name'..."); register(new MyNameCommand(mAnonymouses)); HelpCommand helpCommand = new HelpCommand(this); LOG.info("Registering '/help'..."); register(helpCommand); //    LOG.info("Registering default action'..."); registerDefaultAction(((absSender, message) -> { LOG.log(Level.getLevel(LogLevel.STRANGE.getValue()), "User {} is trying to execute unknown command '{}'.", message.getFrom().getId(), message.getText()); SendMessage text = new SendMessage(); text.setChatId(message.getChatId()); text.setText(message.getText() + " command not found!"); try { absSender.execute(text); } catch (TelegramApiException e) { LOG.error("Error while replying unknown command to user {}.", message.getFrom(), e); } helpCommand.execute(absSender, message.getFrom(), message.getChat(), new String[] {}); })); } @Override public String getBotToken() { return BOT_TOKEN; } //      '/' @Override public void processNonCommandUpdate(Update update) { LOG.info("Processing non-command update..."); if (!update.hasMessage()) { LOG.error("Update doesn't have a body!"); throw new IllegalStateException("Update doesn't have a body!"); } Message msg = update.getMessage(); User user = msg.getFrom(); LOG.info(LogTemplate.MESSAGE_PROCESSING.getTemplate(), user.getId()); if (!canSendMessage(user, msg)) { return; } String clearMessage = msg.getText(); String messageForUsers = String.format("%s:\n%s", mAnonymouses.getDisplayedName(user), msg.getText()); SendMessage answer = new SendMessage(); //     ,     answer.setText(clearMessage); answer.setChatId(msg.getChatId()); replyToUser(answer, user, clearMessage); //       answer.setText(messageForUsers); Stream<Anonymous> anonymouses = mAnonymouses.anonymouses(); anonymouses.filter(a -> !a.getUser().equals(user)) .forEach(a -> { answer.setChatId(a.getChat().getId()); sendMessageToUser(answer, a.getUser(), user); }); } //  ,        private boolean canSendMessage(User user, Message msg) { SendMessage answer = new SendMessage(); answer.setChatId(msg.getChatId()); if (!msg.hasText() || msg.getText().trim().length() == 0) { LOG.log(Level.getLevel(LogLevel.STRANGE.getValue()), "User {} is trying to send empty message!", user.getId()); answer.setText("You shouldn't send empty messages!"); replyToUser(answer, user, msg.getText()); return false; } if(!mAnonymouses.hasAnonymous(user)) { LOG.log(Level.getLevel(LogLevel.STRANGE.getValue()), "User {} is trying to send message without starting the bot!", user.getId()); answer.setText("Firstly you should start bot! Use /start command!"); replyToUser(answer, user, msg.getText()); return false; } if (mAnonymouses.getDisplayedName(user) == null) { LOG.log(Level.getLevel(LogLevel.STRANGE.getValue()), "User {} is trying to send message without setting a name!", user.getId()); answer.setText("You must set a name before sending messages.\nUse '/set_name <displayed_name>' command."); replyToUser(answer, user, msg.getText()); return false; } return true; } private void sendMessageToUser(SendMessage message, User receiver, User sender) { try { execute(message); LOG.log(Level.getLevel(LogLevel.SUCCESS.getValue()), LogTemplate.MESSAGE_RECEIVED.getTemplate(), receiver.getId(), sender.getId()); } catch (TelegramApiException e) { LOG.error(LogTemplate.MESSAGE_LOST.getTemplate(), receiver.getId(), sender.getId(), e); } } private void replyToUser(SendMessage message, User user, String messageText) { try { execute(message); LOG.log(Level.getLevel(LogLevel.SUCCESS.getValue()), LogTemplate.MESSAGE_SENT.getTemplate(), user.getId(), messageText); } catch (TelegramApiException e) { LOG.error(LogTemplate.MESSAGE_EXCEPTION.getTemplate(), user.getId(), e); } } }

Finalmente, inicie el bot:


BotInitializer.java
 package io.example.anonymizerbot; import io.example.anonymizerbot.bot.AnonymizerBot; import org.apache.logging.log4j.LogManager; import org.apache.logging.log4j.Logger; import org.telegram.telegrambots.ApiContextInitializer; import org.telegram.telegrambots.bots.DefaultBotOptions; import org.telegram.telegrambots.meta.ApiContext; import org.telegram.telegrambots.meta.TelegramBotsApi; import org.telegram.telegrambots.meta.exceptions.TelegramApiRequestException; public final class BotInitializer { private static final Logger LOG = LogManager.getLogger(BotInitializer.class); private static final String PROXY_HOST = "xx.xx.xxx.xxx"; private static final int PROXY_PORT = 9999; public static void main(String[] args) { try { LOG.info("Initializing API context..."); ApiContextInitializer.init(); TelegramBotsApi botsApi = new TelegramBotsApi(); LOG.info("Configuring bot options..."); DefaultBotOptions botOptions = ApiContext.getInstance(DefaultBotOptions.class); botOptions.setProxyHost(PROXY_HOST); botOptions.setProxyPort(PROXY_PORT); botOptions.setProxyType(DefaultBotOptions.ProxyType.SOCKS4); LOG.info("Registering Anonymizer..."); botsApi.registerBot(new AnonymizerBot(botOptions)); LOG.info("Anonymizer bot is ready for work!"); } catch (TelegramApiRequestException e) { LOG.error("Error while initializing bot!", e); } } }

Eso es todo! El bot está listo para las primeras pruebas.


Ejemplo de uso


Como ejemplo, considere el siguiente escenario:


  1. 'A' comienza a trabajar con el bot ( /start );
  2. 'A' está intentando enviar un mensaje;
  3. 'A' está intentando establecer un nombre ( /set_name );
  4. 'A' establece el nombre ( /set_name Pendalf );
  5. 'A' envía un mensaje a otros usuarios (que no lo son);
  6. 'B' comienza a trabajar con el bot ( /start );
  7. 'B' establece el nombre ( /set_name Chuck Norris );
  8. 'B' envía un mensaje a otros usuarios;
  9. 'A' ve el mensaje de 'B' y envía un mensaje en respuesta;
  10. 'B' ve la respuesta de 'A' y ya no le escribe ...
