发送告警消息到企业微信群

2024-07-16 17:23:05| 来源: 网络整理| 查看: 265

需求：实现告警信息推送到企业微信群介绍：企业微信支持自建应用推送消息和机器人推送消息，根据不同需求都可实现。

方案一：机器人推送

在群里建一个机器人，复制该机器人的webhook 例如：https://qyapi.weixin.qq.com/cgi-bin/webhook/send?key=123555asdfgh23456

方案二：应用推送

可通过postman测验

一、管理员创建应用->从而拿到应用的secret对应corpsecret，并且拿到企业ID对应corpid二、后台获取到该应用2个小时有效的access_token三、后台调用接口创建群聊，拿到群聊ID对应chatid，可自己指定四、后台调用接口让应用向群发送消息

下面给出代码演示 pom依赖

org.apache.httpcomponents httpcore 4.4.6 org.apache.httpcomponents httpclient 4.5.5 com.alibaba fastjson 1.2.58

工具类，异常自己替换掉

机器人

import java.io.IOException; import java.util.ArrayList; import java.util.HashMap; import java.util.List; import java.util.Map; /** * Created by ZhiWen on 2021/5/20 14:06 * 通过企业微信群的机器人向群内发送消息 */ public class SendWeChatByBot { private static SendWeChatByBot bot= new SendWeChatByBot(); private final String webhook = "https://qyapi.weixin.qq.com/cgi-bin/webhook/send?key=33fc3a3b-c0fb-4046-89dd-ecb99f7c7ba3"; private SendWeChatByBot() {}; public static SendWeChatByBot getBot() { return bot; } /** * 发送文本消息 * @param message * @throws IOException */ public void sendText(String message) throws IOException { ArrayList all = new ArrayList(1); all.add("@all"); sendText(message, all); } /** * 发送文本消息并@用户 * @param message * @param mentionedList * @throws IOException */ public void sendText(String message, List mentionedList) throws IOException { Map body = new HashMap(2); Map text = new HashMap(2); text.put("content", message); text.put("mentioned_list", mentionedList); body.put("msgtype", "text"); body.put("text", text); String result = HttpUtils.doPost(webhook, body); } /** * 发送Markdown消息 * @param message * @param level * @throws IOException */ public void sendMarkDown(String message, Integer level) throws IOException { Map body = new HashMap(2); Map markdown = new HashMap(1); String content = "**嘀嘀嘀，收到报警信息，请相关同事注意。**\n " + ">警报级别："+level+"\n " + ">警报日志："+message; markdown.put("content", content); body.put("msgtype", "markdown"); body.put("markdown", markdown); String result = HttpUtils.doPost(webhook, body); } }

应用

import com.alibaba.fastjson.JSON; import java.io.IOException; import java.util.HashMap; import java.util.Map; /** * Created by ZhiWen on 2021/5/19 15:28 * 通过自建应用向企业微信发送消息 */ public class SendWeChatByApp { private String accessToken; private static SendWeChatByApp sendWeChat = new SendWeChatByApp(); private SendWeChatByApp() { } public static SendWeChatByApp getInstance() { return sendWeChat; } private String getAccessToken() { String corpId = ""; String corpSecret = ""; return getAccessToken(corpId, corpSecret); } /** * 获取秘钥需要添加缓存机制 * @param corpId * @param corpSecret * @return */ public String getAccessToken(String corpId, String corpSecret) { String url = String.format("https://qyapi.weixin.qq.com/cgi-bin/gettoken?corpid=%s&corpsecret=%s", corpId, corpSecret); System.out.println(url); String jsonResult = HttpUtils.doGet(url); Map map = JSON.parseObject(jsonResult, Map.class); String token = map.get("access_token"); System.out.println(token); return token; } /** * 发送群聊消息 * @param token * @param param * @throws IOException */ public void appChatSend(String token, Map param) throws IOException { String url = String.format("https://qyapi.weixin.qq.com/cgi-bin/appchat/send?access_token=%s", token); String result = HttpUtils.doPost(url, param); } /** * 创建群聊请求体 * * @param chatId 群聊ID * @param message 发送的消息 * @return */ public Map appChatTextBody(String chatId, String message) { Map body = new HashMap(4); Map text = new HashMap(1); text.put("content", message); body.put("chatid", chatId); body.put("msgtype", "text"); body.put("text", text); return body; } }

Test

public static void main(String[] args) throws IOException { /*String message = "通过应用自动向企业微信群发送报警信息\n请相关人员查阅并修复!"; SendWeChatByApp sendWeChat = SendWeChatByApp.getInstance(); String accessToken = sendWeChat.getAccessToken("j4j55ffs4345", "Cfsg-A34_uncKu-Hf35qo-z2345_df__NVg"); Map body = sendWeChat.appChatTextBody("dfhaksfhafsduaoenfSJFAOFJAjfsl", message); sendWeChat.appChatSend(accessToken,body);*/ String msg = "我是一个机器人，我给大家拜个年！\n红包红包\n"; SendWeChatByBot bot = SendWeChatByBot.getBot(); //bot.sendText(msg); bot.sendMarkDown(msg,2); }
