使用 spring boot 注册 webhook tg bot

Question

我正在使用 telegrambots-spring-boot-starter v 5.2.0 并尝试注册我的机器人这是我的机器人配置：

bot.url=https://74e437885ee9.ngrok.io

bot.path=亚当

    @Slf4j
@Configuration
public class BotConfig {
  @Value("${bot.url}")
  private String BOT_URL;

  @Bean
  public SetWebhook setWebhookInstance() {
    return SetWebhook.builder().url(BOT_URL).build();
  }
  // Create it as
  @Bean
  public AdamSmithBot adamSmithBot(SetWebhook setWebhookInstance) throws TelegramApiException {
    AdamSmithBot adamSmithBot = new AdamSmithBot(setWebhookInstance);
    //        DefaultWebhook defaultWebhook = new DefaultWebhook();
    //        defaultWebhook.setInternalUrl(BOT_URL);
    //        defaultWebhook.registerWebhook(adamSmithBot);

    TelegramBotsApi telegramBotsApi = new TelegramBotsApi(DefaultBotSession.class);
    log.info("SetWebHook from AdamSmith bot {}", adamSmithBot.getSetWebhook());
    telegramBotsApi.registerBot(adamSmithBot, adamSmithBot.getSetWebhook());
    return adamSmithBot;
  }
}

但它不工作，但是当我发送这个请求时，它工作正常并更新收到我https://api.telegram.org/MY_TOKEN_HERE/setWebhook?url=https://74e437885ee9.ngrok.io

我认为我在 BotConfig 中的错误，但我也发布了我的其他类机器人和控制器：

    public class AdamSmithBot extends SpringWebhookBot {
  @Value("${bot.token}")
  private String TOKEN;

  @Value("${bot.name}")
  private String BOT_USERNAME;

  @Value("${bot.path}")
  private String BOT_PATH;

  public AdamSmithBot(SetWebhook setWebhook) {

    super(setWebhook);
  }

  public AdamSmithBot(DefaultBotOptions options, SetWebhook setWebhook) {
    super(options, setWebhook);
  }

  @Override
  public String getBotUsername() {
    return BOT_USERNAME;
  }

  @Override
  public String getBotToken() {
    return TOKEN;
  }

  @Override
  public BotApiMethod<?> onWebhookUpdateReceived(Update update) {

    if (update.getMessage() != null && update.getMessage().hasText()) {
      Long chatId = update.getMessage().getChatId();
      try {
        execute(new SendMessage(chatId.toString(), "HI HANDSOME " + update.getMessage().getText()));

      } catch (TelegramApiException e) {
        throw new IllegalStateException(e);
      }
    }
    return null;
  }

  @Override
  public String getBotPath() {
    return "adam";
  }
}

控制器：

    @Slf4j
@RestController
public class WebHookBotRecieveController {
    @Autowired
    private AdamSmithBot adamSmithBot;
    @PostMapping("/")
    public void getUpdate(@RequestBody Update update){
        log.info("some update recieved {}",update.toString());
        adamSmithBot.onWebhookUpdateReceived(update);

    }
    @PostMapping("/callback/adam")
    public void getUpdateWithDifferentUrl(@RequestBody Update update){
        log.info("some update recieved {}",update.toString());
        adamSmithBot.onWebhookUpdateReceived(update);

    }
}

注意：我在这里似乎有一些信息： https ://github.com/rubenlagus/TelegramBots/wiki/How-To-Update

他们这样做： https ://i.stack.imgur.com/9JKRT.png

但是当我尝试使用 DefaultWebhook 类时，它会产生 NullPointerException 我做错了什么？

编辑：我重构了一些代码@Value("${bot.url}") private String BOT_URL; - 空值（固定）在哪里，重新加载库，但现在我有那个异常：

好的，我明白了，我不知道 TelegramBotApi 在下面运行一个 grizzly 服务器，这就是我犯错的原因对于那些曾经遇到同样问题的人，我将描述解决方案：让我们从以下事实开始：在 localhost 上的测试我们需要一个公共地址，例如 ngrok ，然后我们必须执行以下操作，在 grizzli 上启动，比如说端口 80（本地主机），指定正确的 ngrok url，然后在上面运行 spring boot 应用程序，比如说端口8080，代码中的例子

例如。 ngrok 转发：转发http://b44ecce72666.ngrok.io -> http://localhost:8080 转发https://b44ecce72666.ngrok.io -> http://localhost:8080

@Slf4j
@Configuration
public class BotConfig {
//  @Value("${bot.url}")
//  @NotNull
//  @NotEmpty
//  private String BOT_URL;

  @Value("${bot.token}")
  @NotNull
  @NotEmpty
  private String TOKEN;

  @Value("${bot.name}")
  @NotNull
  @NotEmpty
  private String BOT_USERNAME;

  @Bean
  public SetWebhook setWebhookInstance() {
    return SetWebhook.builder().url("https://b44ecce72666.ngrok.io").build();
  } // public address, now it is ngrok, in the future it will (i think) be the server address
  // Create it as
  @Bean
  public AdamSmithBot adamSmithBot(SetWebhook setWebhookInstance) throws TelegramApiException {

    AdamSmithBot adamSmithBot = new AdamSmithBot(setWebhookInstance);
    adamSmithBot.setBOT_USERNAME(BOT_USERNAME);
    adamSmithBot.setTOKEN(TOKEN);
    adamSmithBot.setBOT_PATH("adam");
    DefaultWebhook defaultWebhook = new DefaultWebhook();

    defaultWebhook.setInternalUrl(
        "http://localhost:80"); // the port to start the server, on the localhost computer, on the server it
                                // be the server address
    //   defaultWebhook.registerWebhook(adamSmithBot);

    TelegramBotsApi telegramBotsApi = new TelegramBotsApi(DefaultBotSession.class, defaultWebhook);

    log.info("SetWebHook from AdamSmith bot {}", setWebhookInstance);
    adamSmithBot.getBotUsername();
    telegramBotsApi.registerBot(adamSmithBot, setWebhookInstance);
    return adamSmithBot;
   
  }
}

接下来是 webhook bot 的代码：

@Slf4j
@Setter
public class AdamSmithBot extends SpringWebhookBot {
  @Value("${bot.token}")
  private String TOKEN;

  @Value("${bot.name}")
  private String BOT_USERNAME;

  @Value("${bot.path}")
  private String BOT_PATH;
  @Autowired
  private MainService mainService;

  public AdamSmithBot(SetWebhook setWebhook) {

    super(setWebhook);
  }

  public AdamSmithBot(DefaultBotOptions options, SetWebhook setWebhook) {
    super(options, setWebhook);
  }

  @Override
  public String getBotUsername() {

    log.info("BOT_USERNAME FROM ADAM BOT {}",BOT_USERNAME);
    return BOT_USERNAME;
  }

  @Override
  public String getBotToken() {
    return TOKEN;
  }

  @Override
  public BotApiMethod<?> onWebhookUpdateReceived(Update update) { //All messages coming from the grizzly server will trigger this method
    log.info("Message teext {}",update.toString());
    if (update.getMessage() != null && update.getMessage().hasText()) {
      Long chatId = update.getMessage().getChatId();

      List<PartialBotApiMethod<Message>> listOfCommands=  mainService.receiveUpdate(update);
        listOfCommands.forEach(x->{
          try {
          if(x instanceof SendMessage){

              execute((SendMessage)x);

          }
          if(x instanceof SendPhoto){
            execute((SendPhoto) x);
          }
          } catch (TelegramApiException e) {
            e.printStackTrace();
          }
        });


    }
    return null;
  }

  @Override
  public String getBotPath() {
    return "adam"; //any other path here
  }
}

我的代码有些地方过分了，也太花哨了，不过不难弄清楚。 如果您对如何使它变得更好有任何建议，我很想听听他们的意见。

这是来自@handsome 的最有帮助的问题和答案，因此决定在这里发布一些在开始时对我来说并不那么明显的附加信息。

@Configuration
public class BotConfig {

    @Value("${telegram.webhook-host}")
    private String webhookHost;
    @Value("${telegram.endpoint}")
    private String botEndpoint;
    @Value("${telegram.token}")
    private String botToken;
    @Value("${telegram.username}")
    private String botUsername;

    @Bean
    public SetWebhook setWebhookInstance() {
        return SetWebhook.builder().url(webhookHost).build();
    }

    @Bean
    public ParserBot getBot(SetWebhook setWebhook) {
        ParserBot parserBot = new ParserBot(setWebhook);
        parserBot.setBotPath(botEndpoint);
        parserBot.setBotToken(botToken);
        parserBot.setBotUsername(botUsername);
        try {
            DefaultWebhook defaultWebhook = new DefaultWebhook();
            defaultWebhook.setInternalUrl("http://localhost:80");

            TelegramBotsApi telegramBotsApi = new TelegramBotsApi(DefaultBotSession.class, defaultWebhook);
            telegramBotsApi.registerBot(parserBot, parserBot.getSetWebhook());
        } catch (TelegramApiException e) {
            throw new RuntimeException("Can't register telegram bot", e);
        }
        return parserBot;
    }
}

大部分信息都很清楚，但有时有必要说：

1. 您可以通过调用https://api.telegram.org/bot <your_token>/setWebHook?url=<your_url> 手动注册 webhook 端点。在这种情况下，您的 URL 可以是您想要的任何路径。 如果您使用 TelegramBotsApi 注册您的 webhook 端点，那么您的端点将类似于 https://host/callback/ ，例如

telegram.webhook-host=https://12345124.eu.ngrok.io
telegram.endpoint="webhook"

那么你的端点是https://12345124.eu.ngrok.io/callback/webhook是的，你不能设置任何路径到你的端点，但你不需要手动设置它

2. 另一件事。 要在应用程序中激活 WebhookBot，您必须使用 DefaultWebhook 来激活 TelegramBotsApi.useWebhook 属性。 这是根据消息来源。
3. 您的端点必须是 https。 它不能是http。
4. Webhook 只能在端口 80、88、443 或 8443 上设置
