一、钉钉机器人配置

1）添加机器人

2）添加自定义机器人

3）设置机器人参数

4）添加机器人完成

注意：完成后，复制出链接，方便后续测试使用；

Webhook链接组成 = https:// + baseUrl + access_token；

例如：https://oapi.dingtalk.com/robot/send?access_token=82995******45d84；

二、依赖导入

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

三、工具类封装

@Slf4j
public class DingDingUtils {public static void send(String url, String msg) {try {//创建钉钉客户端DingTalkClient client = new DefaultDingTalkClient(url);//构建自定义机器人请求OapiRobotSendRequest request = new OapiRobotSendRequest();//设置固定为文字版信息类型request.setMsgtype("text");//构建自定义机器人文字类型请求OapiRobotSendRequest.Text text = new OapiRobotSendRequest.Text();//调用封装文本信息。text.setContent(msg);request.setText(text);//构建自定义机器人@人范围请求OapiRobotSendRequest.At at = new OapiRobotSendRequest.At();//明确为 true。通知时@所有人at.setIsAtAll(true);request.setAt(at);OapiRobotSendResponse response = client.execute(request);log.info("发送完成，返回值：{}", response.getBody());} catch (ApiException e) {log.error("钉钉接口调用异常：", e);}}}

四、关键字推送消息测试类

1）测试类

@Test
void sendTextTest() {// 钉钉群机器人id号String url = "https://oapi.dingtalk.com/robot/send?access_token=8299504a4255a****************ae4aae697441995f45d84";// hello,为关键字String msg = "hello, 大家好";DingDingUtils.send(url, msg);
}

2）程序输出结果：

3）通知结果：

五、加签推送消息测试类

1）修改机器人配置为加签

2）测试类

@Test
void sendTextTest2() throws Exception {Long timestamp = System.currentTimeMillis();String secret = "SECb2f83dd75fdc0b2***********c50f33ebd36102327e44a8";String stringToSign = timestamp + "\n" + secret;Mac mac = Mac.getInstance("HmacSHA256");mac.init(new SecretKeySpec(secret.getBytes("UTF-8"), "HmacSHA256"));byte[] signData = mac.doFinal(stringToSign.getBytes("UTF-8"));String sign = URLEncoder.encode(new String(Base64.encodeBase64(signData)),"UTF-8");System.out.println(sign);// 钉钉群机器人id号String baseUrl = "https://oapi.dingtalk.com/robot/send?access_token=8299504a4255a****************ae4aae697441995f45d84";String msg = "这是一条加签测试的消息！";String fullUrl = String.format(baseUrl + "&timestamp=%s&sign=%s", timestamp, sign);DingDingUtils.send(fullUrl, msg);
}

3）程序输出结果

4）通知结果
