使用Java给钉钉群发消息

1.安装依赖

2.编写工具类

3.测试

安全设置

Webhook

代码编写

运行测试

4.艾特全部功能

1.安装依赖

 <dependency>
            <groupId>com.taobao.dingding</groupId>
            <artifactId>taobao-sdk</artifactId>
            <version>1.0.0</version>
</dependency>

2.编写工具类

DingDingUtils


@Slf4j
public class DingDingUtils {

    private static String ROBOT_SEND_MESSAGE_URL = "https://oapi.dingtalk.com/robot/send?access_token=";

    /**
     * 发送钉钉群消息
     * @param content
     */
    public static void sendDingDingGroupMsg(String accessToken, String content) {
        String textMsg = "{ \"msgtype\": \"text\", \"text\": {\"content\": \"" + content + "\"}}";
        dealDingDingMsgSend(accessToken, textMsg);
    }

    /**
     * 处理发送的钉钉消息
     *
     * @param textMsg
     */
    private static void dealDingDingMsgSend(String accessToken, String textMsg) {
        HttpClient httpclient = HttpClients.createDefault();
        String robotSendMessageUrl = ROBOT_SEND_MESSAGE_URL + accessToken;
        HttpPost httppost = new HttpPost(robotSendMessageUrl);
        httppost.addHeader("Content-Type", "application/json; charset=utf-8");
        StringEntity se = new StringEntity(textMsg, "utf-8");
        httppost.setEntity(se);

        try {
            HttpResponse response = httpclient.execute(httppost);
            if (response.getStatusLine().getStatusCode() == HttpStatus.SC_OK) {
                String result = EntityUtils.toString(response.getEntity(), "utf-8");
                log.info("Send DingDing Message Success! Response Content: " + JSON.toJSONString(result));
            }
        } catch (Exception e) {
            log.error("Send DingDing Message Error! Error Message：" + e.getMessage(), e);
        }
    }

}

3.测试

首先在钉钉新建一个群，并且添加机器人

安全设置

我设置了关键字，消息里面有这个hello关键字才能成功发送消息

Webhook

记录自己的Webhook，是进行发消息的途径

代码编写

public static void main(String[] args) {
        String str =  "hello,钉钉";
        String token  = "这里填写你自己的钉钉token";
        DingDingUtils.sendDingDingGroupMsg(token,str);
}

运行测试

4.艾特全部功能

钉钉提供了艾特全部功能

{
    "at": {
        "atMobiles":[
            "180xxxxxx"
        ],
        "atUserIds":[
            "user123"
        ],
        "isAtAll": false
    },
    "text": {
        "content":"我就是我, @XXX 是不一样的烟火"
    },
    "msgtype":"text"
}

修改sendDingDingGroupMsg方法,第三个参数表示是否艾特全部

/**
     * 发送钉钉群消息
     * @param content
     */
    public static void sendDingDingGroupMsg(String accessToken, String content,Boolean atAll) {
        String textMsg = "{ \"msgtype\": \"text\", \"text\": {\"content\": \"" + content + "\"},\"at\": {\"isAtAll\": \"" + atAll + "\"}}";
        dealDingDingMsgSend(accessToken, textMsg);
    }
