如何修复“不能同时请求直接通知和查询通知”

Question

使用 Twilio notify 发送通知时出现异常。

如果我在不发送 SMS 的情况下发送通知，则在使用相同的 Twilio NotificationCreator bean 发送 SMS 后发送通知时，代码会引发异常，它工作正常。

这是 Twilio 通知的配置

TwilioConfig.java

@Configuration
public class TwilioConfig {

  @Value("${twilio.accountSid}")
  private String accountSid;

  @Value("${twilio.authToken}")
  private String authToken;

  @Value("${twilio.serviceId}")
  private String serviceId;

  @Bean
  public TwilioRestClient twilioRestClient() {
    return new TwilioRestClient.Builder(accountSid, authToken)
        .build();
  }

  @Bean
  public NotificationCreator notificationCreator() {
    return Notification.creator(serviceId);
  }

}

通知服务.java

@Service
public class NotificationService {

  @Autowired
  private TwilioRestClient twilioRestClient;

  @Autowired
  private NotificationCreator notificationCreator;

  public void sendPushNotification(String title, String body, List<String> identities) {
    try {
      Notification notification = notificationCreator
          .setTitle(title)
          .setBody(body)
          .setIdentity(identities)
          .create(twilioRestClient);

    } catch (TwilioException e) {
      log.error("An exception occurred trying to send a notification to {}, exception: {}", identities, e.getMessage());
    }
  }

  public void createAndSendSms(String body, String to) {
    try {
      List<String> toBindings = Collections.singletonList(
          "{\"binding_type\":\"sms\",\"address\":\"" + to + "\"}"
      );

      Notification notification = notificationCreator
          .setBody(body)
          .setToBinding(toBindings)
          .create(twilioRestClient);

    } catch (TwilioException e) {
      log.error("An exception occurred trying to send a message to {}, exception: {}", to, e.getMessage());
    }
  }

}

您应该必须从 TwilioConfig.java 文件中删除 bean 创建方法。

TwilioConfig.java

 @Bean
  public NotificationCreator notificationCreator() {
    return Notification.creator(serviceId);
  }

相反，每次发送通知或短信时，都使用 NotificationCreator bean 的新对象。

例如 ：

@Service
public class NotificationService {

  @Value("${twilio.serviceId}")
  private String serviceId;

  public void sendPushNotification(String title, String body, List<String> identities) {
    try {

      // Notification notification = notificationCreator
      Notification notification = Notification.creator(serviceId)
          .setTitle(title)
          .setBody(body)
          .setIdentity(identities)
          .create(twilioRestClient);

    } catch (TwilioException e) {
      log.error("An exception occurred trying to send a notification to {}, exception: {}", identities, e.getMessage());
    }
  }

  public void createAndSendSms(String body, String to) {
    try {
      List<String> toBindings = Collections.singletonList(
          "{\"binding_type\":\"sms\",\"address\":\"" + to + "\"}"
      );

      // Notification notification = notificationCreator
      Notification notification = Notification.creator(serviceId)
          .setBody(body)
          .setToBinding(toBindings)
          .create(twilioRestClient);

    } catch (TwilioException e) {
      log.error("An exception occurred trying to send a message to {}, exception: {}", to, e.getMessage());
    }
  }
}
