红帽全球峰会343.9. 获取 Chat ID
如果要在事件发生时将消息推送到特定的 Telegram 聊天，则需要检索对应的聊天 ID。telegram 客户端中目前不显示聊天 ID，但您可以使用简单路由获取它。
首先，将 bot 添加到您要推送消息的聊天中，然后运行以下命令：
from("telegram:bots/123456789:insertYourAuthorizationTokenHere")
.to("log:INFO?showHeaders=true");
from("telegram:bots/123456789:insertYourAuthorizationTokenHere")
.to("log:INFO?showHeaders=true");
bot 收到的任何消息都会转储到您的日志，并提供关于聊天(CamelTelegramChatId 标头)的信息。
获得聊天 ID 后，您可以使用以下示例路由向其推送消息。
from("timer:tick")
.setBody().constant("Hello")
to("telegram:bots/123456789:insertYourAuthorizationTokenHere?chatId=123456")
from("timer:tick")
.setBody().constant("Hello")
to("telegram:bots/123456789:insertYourAuthorizationTokenHere?chatId=123456")
请注意，对应的 URI 参数只是 chatId。
