钉钉企业内部H5微应用或小程序之钉消息推送

news 来源：原创 2024/9/29 9:36:48

钉钉简单的推送钉消息

一、钉钉准备工作

首先进入钉钉开放平台你得有企业内部微应用或者小程序 没有创建的话去看我另一篇文章有说明

钉钉开放平台创建企业内部H5微应用或者小程序-CSDN博客

看不懂话也可以参考官方文档：创建应用 - 钉钉开放平台

二、开发的准备工作

1.pom的导入

<!-- 钉钉SDK -->
<dependency><groupId>com.aliyun</groupId><artifactId>dingtalk</artifactId><version>1.2.15</version>
</dependency>
<dependency><groupId>com.aliyun</groupId><artifactId>alibaba-dingtalk-service-sdk</artifactId><version>2.0.0</version>
</dependency>

2.配置文件（yml配置文件）

#钉钉信息
dingtalk:corpid: dingxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxappkey: dingxxxxxxxxxxxxxxxxappsecret: 89QA-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx-xxxxagentid: 2xxxxxxxxx

这里的配置信息是你的应用信息（在钉钉后台-应用管理）

三、代码实现

添加工具类获取钉钉AccessToken

/*** 钉钉工具类* @date 2023-07-07 9:30*/
@Slf4j
@Component
public class DingTalkUtil {@Value("${dingtalk.appKey}")private String appKey;@Value("${dingtalk.appSecret}")private String appSecret;/*** 获取钉钉AccessToken** @return*/public String getAccessToken() {try {DingTalkClient client = new DefaultDingTalkClient("https://oapi.dingtalk.com/gettoken");OapiGettokenRequest req = new OapiGettokenRequest();req.setAppkey(appKey);req.setAppsecret(appSecret);req.setHttpMethod("GET");OapiGettokenResponse rsp = client.execute(req);if (rsp.getErrcode() == 0) {return rsp.getAccessToken();} else {throw new JeecgBootException("获取dingtalk授权失败!");}} catch (ApiException e) {e.printStackTrace();}return null;}}

调用钉钉接口之前都是需要用到access_token校验的，接着调用用户电话获得钉钉的userId（某个人在企业里的唯一ID）


/*** 获取钉钉的用户的userid** @param phone 用户电话* @return 钉钉用户内部userId*/public String getDingTalkUserId(String phone) throws Exception {String accessToken = this.getAccessToken();if (accessToken == null) {throw new Exception("获取到access_token失败！");}try {DingTalkClient client = new DefaultDingTalkClient("https://oapi.dingtalk.com/topapi/v2/user/getbymobile");OapiV2UserGetbymobileRequest req = new OapiV2UserGetbymobileRequest();req.setMobile(phone);OapiV2UserGetbymobileResponse rsp = client.execute(req, accessToken);String userId = rsp.getResult().getUserid();return userId;} catch (ApiException e) {log.error("请求获取钉钉用户的userid失败:{}", e.getErrMsg());}return null;}

发送消息工具类（可给单个或多个人发送）

package org.jeecg.modules.aigoes.util;import com.alibaba.fastjson.JSONObject;
import lombok.extern.slf4j.Slf4j;
import org.jeecg.common.util.TokenUtils;
import org.jeecg.modules.message.util.DingTalkUtil;
import org.jeecg.modules.system.entity.SysTenant;
import org.jeecg.modules.system.service.ISysTenantService;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;import javax.annotation.Resource;
import java.io.*;
import java.net.HttpURLConnection;
import java.net.URL;
import java.util.List;
import java.util.stream.Collectors;/*** rwy* @date 2023-07-07 9:30*/
@Slf4j
@Component
public class MessageUtils {@Resourceprivate DingTalkUtil dingTalkUtil;// 钉钉发送消息给指定用户列表public void sendMessageNew(List<String> userIdList, String picUrl, String messageUrlDing, String text, String title) throws Exception {String accessToken = dingTalkUtil.getAccessToken();String messageUrl = "https://oapi.dingtalk.com/topapi/message/corpconversation/asyncsend_v2?access_token=" + accessToken;JSONObject jsonObject = new JSONObject();//钉钉后台应用的agent_idjsonObject.put("agent_id", sysTenant.getAgentId());//推送的userId                                                              jsonObject.put("userid_list",userIdList.stream().collect(Collectors.joining(",")));jsonObject.put("to_all_user", false);JSONObject msgObj = new JSONObject();//消息类型msgObj.put("msgtype", "action_card");JSONObject textObj = new JSONObject();//标题textObj.put("title", title);//内容textObj.put("markdown", text);//按钮名称textObj.put("single_title", picUrl);//跳转地址 填小程序莫页面地址或微应用的textObj.put("single_url", messageUrlDing);msgObj.put("action_card",textObj);jsonObject.put("msg", msgObj);String jsonBody = jsonObject.toJSONString();System.out.println(jsonBody);//发送POST请求JSONObject response = httpPost(messageUrl, jsonBody, "UTF-8");System.out.println(response);}public JSONObject httpPost(String url, String requestData, String charset) throws IOException {URL apiUrl = new URL(url);HttpURLConnection connection = (HttpURLConnection) apiUrl.openConnection();connection.setRequestMethod("POST");connection.setDoOutput(true);// 设置请求头部connection.setRequestProperty("Content-Type", "application/json;charset=" + charset);// 发送请求数据try (OutputStream outputStream = connection.getOutputStream()) {outputStream.write(requestData.getBytes(charset));outputStream.flush();}// 获取响应结果try (InputStream inputStream = connection.getInputStream();BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream, charset))) {StringBuilder response = new StringBuilder();String line;while ((line = reader.readLine()) != null) {response.append(line);}return JSONObject.parseObject(response.toString());}} }

这里需要注意的是你选择的消息通知类型 - 钉钉开放平台，我这里选择是卡片消息 因为卡片消息支持整体跳转ActionCard样式和独立跳转ActionCard样式以及可以展示图片和添加多个按钮样式和可玩性比较高。

测试发送钉消息

注意事项：小程序链接和微应用微应用唯一区别在这跳转地址要跳转小程序前面是需要加 eapp:// 列如以下是这样的 eapp://pagesA/pages/Home/h-psy/ 而微应用不用加

/*** 发送钉消息* @return* @throws Exception*/@GetMapping("/cs2")public Result<?> cs() throws Exception {String headteacherId = "661xxxxxxxxxxxxxxx";messageUtils.sendMessageNew(Collections.singletonList(headteacherId),"点击查看详情","pagesA/pages/Home/h-psy/mood","### <font color=#04CFFF>测试天气消息</font>  \n  **天气还不错。**","天气报告");return Result.OK();}
