Contoh menggunakan perpustakaan Java untuk membuat bot Telegram

Setiap pengembang (dan tidak hanya) yang menggunakan Telegram dalam kehidupan sehari-hari, setidaknya sekali memikirkan bagaimana rasanya membuat bot mereka sendiri, betapa sulitnya itu dan bahasa pemrograman apa yang terbaik untuk digunakan.


Saya dapat memberikan jawaban yang paling sederhana (dan mungkin yang paling benar) untuk semua pertanyaan ini: semuanya tergantung pada diri Anda sendiri, pengetahuan dan niat Anda.


... Tetapi dalam artikel singkat ini, saya akan menunjukkan bagaimana Anda dapat membuat bot Anda sendiri di Jawa dan itu cukup menarik dan tidak rumit.


Kami akan menggunakan pustaka untuk bekerja dengan API Telegram Bots dan ekstensinya , yang memungkinkan kami membuat perintah sendiri (' /custom_cmd ') dan memprosesnya dengan cara yang sederhana.


Tugas bot adalah untuk mendaftarkan pengguna dan mengirim pesan dari nama yang ditentukan ke pengguna bot lainnya.


Pembuatan proyek dan persiapan baru


1. Tambahkan dependensi ke proyek


Buat proyek pakar baru dan edit pom.xml , tambahkan dependensi yang diperlukan untuk itu:


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 - perpustakaan untuk bekerja dengan API Telegram Bots , berisi kelas dan metode untuk berinteraksi dengan layanan Telegram dan beberapa ekstensi dari kelas-kelas ini.


2. Membuat akun untuk bot


Untuk melakukan ini, kita perlu menghubungi bot BotFather untuk bantuan:


  • temukan bot dalam pencarian;
  • jalankan perintah "/ mulai";
  • jalankan perintah "/ newbot";
  • mari kita tentukan beberapa nama untuk bot kita (harus diakhiri dengan "Bot"). Saya menyebutnya "ExampleOfAnonymizerBot".

Setelah menjalankan perintah ini, kita akan mendapatkan token yang kita perlukan untuk menggunakan API Bot. (7xxxxxxx2: Axxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx0)






Implementasi


1. Model pengirim pesan anonim


Data yang kami butuhkan dari setiap pengguna:


  • Pengguna pengguna - informasi tentang pengguna Telegram;
  • Obrolan mChat - informasi obrolan pengguna dan bot;
  • String mDisplayedName - nama dari mana pengguna akan mengirim pesan ke pengguna bot lainnya.

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; } }

Tambahkan layanan yang berisi metode yang biasa digunakan untuk memanipulasi banyak pengguna anonim.


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. Antarmuka bot


Perintah khusus apa pun harus diwariskan dari BotCommand dan menerapkan metode
execute(AbsSender sender, User user, Chat chat, String[] strings) , yang digunakan untuk memproses perintah pengguna.


Setelah kami memproses perintah pengguna, kami dapat mengirimnya respons menggunakan metode execute dari kelas AbsSender , yang mengambil execute(AbsSender sender, User user, Chat chat, String[] strings) disebutkan di atas execute(AbsSender sender, User user, Chat chat, String[] strings) .


Selanjutnya, agar tidak membungkus metode AbsSender.execute setiap kali, yang dapat melempar TelegramApiException , dalam try-catch , dan agar tidak menampilkan output log seragam di setiap perintah, kami akan membuat kelas AnonymizerCommand , dan kami akan mewarisi perintah khusus kami darinya (kami akan memberikan penanganan pengecualian dalam contoh ini):


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); } } }

Tetapkan perintah yang akan ditanggapi oleh bot kami:


  • /start - buat Anonymous baru tanpa nama dan tambahkan ke koleksi 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 - menampilkan informasi tentang semua perintah yang tersedia kepada pengguna (konstruktor berbeda dari yang lain karena Anda harus meneruskan ICommandRegistry , yang berisi semua perintah khusus);

HelpCommand.java
 package io.example.anonymizerbot.command; import io.example.anonymizerbot.logger.LogTemplate; import org.telegram.telegrambots.extensions.bots.commandbot.commands.ICommandRegistry; 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 HelpCommand extends AnonymizerCommand { private final ICommandRegistry mCommandRegistry; public HelpCommand(ICommandRegistry commandRegistry) { super("help", "list all known commands\n"); mCommandRegistry = commandRegistry; } @Override public void execute(AbsSender absSender, User user, Chat chat, String[] strings) { log.info(LogTemplate.COMMAND_PROCESSING.getTemplate(), user.getId(), getCommandIdentifier()); StringBuilder helpMessageBuilder = new StringBuilder("<b>Available commands:</b>"); mCommandRegistry.getRegisteredCommands().forEach(cmd -> helpMessageBuilder.append(cmd.toString()).append("\n")); SendMessage helpMessage = new SendMessage(); helpMessage.setChatId(chat.getId().toString()); helpMessage.enableHtml(true); helpMessage.setText(helpMessageBuilder.toString()); execute(absSender, helpMessage, user); } }

  • /set_name - /set_name pengguna nama dari mana pesan anonim akan dikirim;

SetNameCommand.java
 package io.example.anonymizerbot.command; import io.example.anonymizerbot.logger.LogLevel; import io.example.anonymizerbot.logger.LogTemplate; 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 SetNameCommand extends AnonymizerCommand { private final AnonymousService mAnonymouses; public SetNameCommand(AnonymousService anonymouses) { super("set_name", "set or change name that will be displayed with your messages\n"); mAnonymouses = anonymouses; } @Override public void execute(AbsSender absSender, User user, Chat chat, String[] strings) { log.info(LogTemplate.COMMAND_PROCESSING.getTemplate(), user.getId(), getCommandIdentifier()); SendMessage message = new SendMessage(); message.setChatId(chat.getId().toString()); if (!mAnonymouses.hasAnonymous(user)) { log.log(Level.getLevel(LogLevel.STRANGE.getValue()), "User {} is trying to execute '{}' without starting the bot!", user.getId(), getCommandIdentifier()); message.setText("Firstly you should start the bot! Execute '/start' command!"); execute(absSender, message, user); return; } String displayedName = getName(strings); if (displayedName == null) { log.log(Level.getLevel(LogLevel.STRANGE.getValue()), "User {} is trying to set empty name.", user.getId()); message.setText("You should use non-empty name!"); execute(absSender, message, user); return; } StringBuilder sb = new StringBuilder(); if (mAnonymouses.setUserDisplayedName(user, displayedName)) { if (mAnonymouses.getDisplayedName(user) == null) { log.info("User {} set a name '{}'", user.getId(), displayedName); sb.append("Your displayed name: '").append(displayedName) .append("'. Now you can send messages to bot!"); } else { log.info("User {} has changed name to '{}'", user.getId(), displayedName); sb.append("Your new displayed name: '").append(displayedName).append("'."); } } else { log.log(Level.getLevel(LogLevel.STRANGE.getValue()), "User {} is trying to set taken name '{}'", user.getId(), displayedName); sb.append("Name ").append(displayedName).append(" is already in use! Choose another name!"); } message.setText(sb.toString()); execute(absSender, message, user); } private String getName(String[] strings) { if (strings == null || strings.length == 0) { return null; } String name = String.join(" ", strings); return name.replaceAll(" ", "").isEmpty() ? null : name; } }

  • /my_name - menampilkan nama pengguna saat ini;

MyNameCommand.java
 package io.example.anonymizerbot.command; import io.example.anonymizerbot.logger.LogLevel; import io.example.anonymizerbot.logger.LogTemplate; 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 MyNameCommand extends AnonymizerCommand { private final AnonymousService mAnonymouses; public MyNameCommand(AnonymousService anonymouses) { super("my_name", "show your current name that will be displayed with your messages\n"); mAnonymouses = anonymouses; } @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.hasAnonymous(user)) { sb.append("You are not in bot users' list! Send /start command!"); log.log(Level.getLevel(LogLevel.STRANGE.getValue()), "User {} is trying to execute '{}' without starting the bot.", user.getId(), getCommandIdentifier()); } else if(mAnonymouses.getDisplayedName(user) == null) { sb.append("Currently you don't have a name.\nSet it using command:\n'/set_name &lt;displayed_name&gt;'"); log.log(Level.getLevel(LogLevel.STRANGE.getValue()), "User {} is trying to execute '{}' without having a name.", user.getId(), getCommandIdentifier()); } else { log.info("User {} is executing '{}'. Name is '{}'.", user.getId(), getCommandIdentifier(), mAnonymouses.getDisplayedName(user)); sb.append("Your current name: ").append(mAnonymouses.getDisplayedName(user)); } message.setText(sb.toString()); execute(absSender, message, user); } }

  • /stop - menghapus pengguna dari koleksi anonim.

StopCommand.java

Bye!"); } else { log.log(Level.getLevel(LogLevel.STRANGE.getValue()), "User {} is trying to execute '{}' without having executed 'start' before!", user.getId(), getCommandIdentifier()); sb.append("You were not in bot users' list. Bye!"); } message.setText(sb.toString()); execute(absSender, message, user); } }

3. Inisialisasi dan peluncuran bot


Kelas bot di mana semua perintah khusus, penangan pesan non-perintah, dan perintah yang tidak dikenal terdaftar.


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); } } }

Akhirnya, luncurkan 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); } } }

Itu saja! Bot siap untuk tes pertama.


Contoh penggunaan


Sebagai contoh, pertimbangkan skenario berikut:


  1. 'A' mulai bekerja dengan bot ( /start );
  2. 'A' sedang mencoba mengirim pesan;
  3. 'A' sedang mencoba untuk menetapkan nama ( /set_name );
  4. 'A' menetapkan nama ( /set_name Pendalf );
  5. 'A' mengirim pesan ke pengguna lain (yang bukan);
  6. 'B' mulai bekerja dengan bot ( /start );
  7. 'B' menetapkan nama ( /set_name Chuck Norris );
  8. 'B' mengirim pesan ke pengguna lain;
  9. 'A' melihat pesan dari 'B' dan mengirim pesan sebagai tanggapan;
  10. 'B' melihat jawaban dari 'A' dan tidak lagi menulis kepadanya ...
