javaweb利用钉钉机器人向钉钉群推送消息（解决中文乱码）
可以参考 官方文档：https://open-doc.dingtalk.com/docs/doc.htm?spm=a219a.7629140.0.0.karFPe&treeId=257&articleId=105735&docType=1
1.新建一个群。添加自定义机器人。获取自定义机器人webhook。
2.封装消息实体类。
package com.thinkgem.wlw.modules.midea.dingTalkTest; import com.alibaba.fastjson.JSON; import com.thinkgem.wlw.common.utils.StringUtils; import java.util.HashMap; import java.util.List; import java.util.Map; /** * @Author: zhouhe * @Date: 2019/6/20 17:25 */ public class TextMessage { private String text; private List<String> atMobiles; private boolean isAtAll; public TextMessage(String text) { this.text = text; } public String getText() { return text; } public void setText(String text) { this.text = text; } public List<String> getAtMobiles() { return atMobiles; } public void setAtMobiles(List<String> atMobiles) { this.atMobiles = atMobiles; } public boolean isAtAll() { return isAtAll; } public void setIsAtAll(boolean isAtAll) { this.isAtAll = isAtAll; } public String toJsonString() { Map<String, Object> items = new HashMap(); items.put("msgtype", "text"); Map<String, String> textContent = new HashMap(); if (StringUtils.isBlank(text)) { throw new IllegalArgumentException("text should not be blank"); } textContent.put("content", text); items.put("text", textContent); Map<String, Object> atItems = new HashMap(); if (atMobiles != null && !atMobiles.isEmpty()) { atItems.put("atMobiles", atMobiles); } if (isAtAll) { atItems.put("isAtAll", isAtAll); } items.put("at", atItems); return JSON.toJSONString(items); } }
3.封装发送消息结果实体类
package com.thinkgem.wlw.modules.midea.dingTalkTest; import com.alibaba.fastjson.JSON; import java.util.HashMap; import java.util.Map; /** * @Author: zhouhe * @Date: 2019/6/20 17:26 */ public class SendResult { private boolean isSuccess; private Integer errorCode; private String errorMsg; public boolean isSuccess() { return isSuccess; } public void setIsSuccess(boolean isSuccess) { this.isSuccess = isSuccess; } public Integer getErrorCode() { return errorCode; } public void setErrorCode(Integer errorCode) { this.errorCode = errorCode; } public String getErrorMsg() { return errorMsg; } public void setErrorMsg(String errorMsg) { this.errorMsg = errorMsg; } @Override public String toString() { Map<String, Object> items = new HashMap<String, Object>(); items.put("errorCode", errorCode); items.put("errorMsg", errorMsg); items.put("isSuccess", isSuccess); return JSON.toJSONString(items); } }
4.发送消息通用类
package com.thinkgem.wlw.modules.midea.dingTalkTest; import com.alibaba.fastjson.JSONObject; import org.apache.http.HttpResponse; import org.apache.http.HttpStatus; import org.apache.http.client.HttpClient; import org.apache.http.client.methods.HttpPost; import org.apache.http.entity.StringEntity; import org.apache.http.impl.client.HttpClients; import org.apache.http.util.EntityUtils; import java.io.IOException; /** * @Author: zhouhe * @Date: 2019/6/20 17:26 */ public class RobotClient { public static SendResult send(String webhook, TextMessage message) throws IOException { HttpClient httpclient = HttpClients.createDefault(); HttpPost httppost = new HttpPost(webhook); httppost.addHeader("Content-Type", "application/json; charset=utf-8"); StringEntity se = new StringEntity(message.toJsonString(), "utf-8"); httppost.setEntity(se); SendResult sendResult = new SendResult(); HttpResponse response = httpclient.execute(httppost); if (response.getStatusLine().getStatusCode() == HttpStatus.SC_OK) { String result = EntityUtils.toString(response.getEntity()); JSONObject obj = JSONObject.parseObject(result); Integer errcode = obj.getInteger("errcode"); sendResult.setErrorCode(errcode); sendResult.setErrorMsg(obj.getString("errmsg")); sendResult.setIsSuccess(errcode.equals(0)); } return sendResult; } }
5.发送文本消息类
package com.thinkgem.wlw.modules.midea.dingTalkTest; import groovy.util.logging.Slf4j; import java.util.ArrayList; /** * @Author: zhouhe * @Date: 2019/6/20 17:32 */ @Slf4j public class SendTextMessage { //机器人消息token public static String WEBHOOK_TOKEN = "https://oapi.dingtalk.com/robot/send?access_token=xxx"; private static RobotClient robot = new RobotClient(); /** * 发送普通文本消息 * * @param message * @return */ public static SendResult send(String message) { TextMessage textMessage = new TextMessage(message); SendResult sendResult = null; try { sendResult = robot.send(WEBHOOK_TOKEN, textMessage); } catch (Exception e) { // log.error("===> send robot message error:", sendResult); } return sendResult; } /** * 发送文本消息 可以@部分人 * * @param message * @param atMobiles 要@人的电话号码 ArrayList<String> * @return */ public static SendResult sendWithAt(String message, ArrayList<String> atMobiles) { TextMessage textMessage = new TextMessage(message); SendResult sendResult = null; textMessage.setAtMobiles(atMobiles); try { sendResult = robot.send(WEBHOOK_TOKEN, textMessage); } catch (Exception e) { // log.error("===> send robot message atPeople error:", sendResult); } return sendResult; } /** * 发送文本消息 并@所有人 * * @param message * @return */ public static SendResult sendWithAtAll(String message) { TextMessage textMessage = new TextMessage(message); SendResult sendResult = null; textMessage.setIsAtAll(false); try { sendResult = robot.send(WEBHOOK_TOKEN, textMessage); } catch (Exception e) { // log.error("===> send robot message atAll error:", sendResult); } return sendResult; } }
6.调用
package com.thinkgem.wlw.modules.midea.dingTalk; import com.thinkgem.wlw.modules.midea.dingTalkTest.SendTextMessage; import java.util.HashMap; import java.util.Map; /** * @Author: zhouhe * @Date: 2019/6/20 14:52 */ public class SendMessage { public static void main(String[] args){ SendTextMessage.sendWithAtAll("我是测试的！！！"); } }
效果（钉钉消息）：
@Slf4j maven依赖：
<dependency> <groupId>org.codehaus.groovy</groupId> <artifactId>groovy-all</artifactId> <version>2.4.5</version> </dependency>
注：如果钉钉机器人中设置了关键字，那么发送的消息内容必须包含关键字才行，否则发送不出去。详见钉钉开发文档
