[TG开发]简单的回声机器人

你好! 如果你想了解如何在Java上编写Telegram机器人，你来对地方了!

准备启动

机器人API基于HTTP请求，但在本书中我将使用Rubenlagus的Java库

安装库

你可以使用不同的方法安装TelegramBots库, 我这里使用Maven

<dependency>
<groupId>org.telegram</groupId>
<artifactId>telegrambots</artifactId>
<version>Latest</version>
</dependency>

让我们开始编码吧

在本节课中，我们将编写一个简单的机器人，它会回显我们发送给它的所有内容。现在，打开inteliidea，创建一个新项目。你可以随意给它起个名字。

import org.telegram.telegrambots.api.methods.send.SendMessage;
import org.telegram.telegrambots.api.objects.Update;
import org.telegram.telegrambots.bots.TelegramLongPollingBot;
import org.telegram.telegrambots.exceptions.TelegramApiException;

public class MyAmazingBot extends TelegramLongPollingBot {
@Override
public void onUpdateReceived(Update update) {
// TODO
}

@Override
public String getBotUsername() {
// TODO
return null;
}

@Override
public String getBotToken() {
// TODO
return null;
}
}

`getBotUsername()'和`getBotToken ()`必须返回从 @BotFather获取的机器人的用户名和令牌。

import org.telegram.telegrambots.api.methods.send.SendMessage;
import org.telegram.telegrambots.api.objects.Update;
import org.telegram.telegrambots.bots.TelegramLongPollingBot;
import org.telegram.telegrambots.exceptions.TelegramApiException;

public class MyAmazingBot extends TelegramLongPollingBot {
@Override
public void onUpdateReceived(Update update) {
// TODO
}

@Override
public String getBotUsername() {
// Return bot username
// If bot username is @MyAmazingBot, it must return 'MyAmazingBot'
return "MyAmazingBot";
}

@Override
public String getBotToken() {
// Return bot token from BotFather
return "12345:qwertyuiopASDGFHKMK";
}
}

如前所述，我们希望它能够回复我们发送给它的每条文本。`onUpdateReceived(Updateupdate)`方法就是为此而设的。当接收到一条更新时，该方法会被调用。

@Override
public void onUpdateReceived(Update update) {

// We check if the update has a message and the message has text
if (update.hasMessage() && update.getMessage().hasText()) {
// Set variables
String message_text = update.getMessage().getText();
long chat_id = update.getMessage().getChatId();

SendMessage message = new SendMessage() // Create a message object object
.setChatId(chat_id)
.setText(message_text);
try {
execute(message); // Sending our message object to user
} catch (TelegramApiException e) {
e.printStackTrace();
}
}
}

import org.telegram.telegrambots.ApiContextInitializer;
import org.telegram.telegrambots.TelegramBotsApi;
import org.telegram.telegrambots.exceptions.TelegramApiException;
public class Main {
public static void main(String[] args) {

// TODO Initialize Api Context

// TODO Instantiate Telegram Bots API

// TODO Register our bot
}
}

import org.telegram.telegrambots.ApiContextInitializer;
import org.telegram.telegrambots.TelegramBotsApi;

public class Main {
public static void main(String[] args) {

}
}

import org.telegram.telegrambots.ApiContextInitializer;

import org.telegram.telegrambots.exceptions.TelegramApiException;
public class Main {
public static void main(String[] args) {
// Initialize Api Context
ApiContextInitializer.init();
// Instantiate Telegram Bots API
TelegramBotsApi botsApi = new TelegramBotsApi();

// TODO Register our bot
}
}

import org.telegram.telegrambots.ApiContextInitializer;

import org.telegram.telegrambots.exceptions.TelegramApiException;
public class Main {
public static void main(String[] args) {
// Initialize Api Context
ApiContextInitializer.init();

// Instantiate Telegram Bots API
TelegramBotsApi botsApi = new TelegramBotsApi();

// Register our bot
try {
botsApi.registerBot(new MyAmazingBot());
} catch (TelegramApiException e) {
e.printStackTrace();
}
}
}

// Register our bot
try {

} catch (TelegramApiException e) {

}
}
}

public class MyAmazingBot extends TelegramLongPollingBot {
@Override
public void onUpdateReceived(Update update) {

// We check if the update has a message and the message has text
if (update.hasMessage() && update.getMessage().hasText()) {
// Set variables
String message_text = update.getMessage().getText();
long chat_id = update.getMessage().getChatId();

SendMessage message = new SendMessage() // Create a message object object
.setChatId(chat_id)
.setText(message_text);
try {
execute(message); // Sending our message object to user
} catch (TelegramApiException e) {
e.printStackTrace();
}
}
}

@Override
public String getBotUsername() {

return "MyAmazingBot";
}

@Override

return "12345:qwertyuiopASDGFHKMK";
}
}
