java通过钉钉机器人发消息

钉钉自定义机器人使用 加签的配置 发送消息

注意：内部群才可以创建自定义机器人

1、获得的钉钉配置信息workhook和secret

//url路径private String URL = "https://oapi.dingtalk.com/robot/send?access_token=08ebaa04f98f7faacbacd80fa879463d85cdccdd6cef184ef01bb5a8b6ae6f6c";
//加签密钥private String DINGDING_SECRET = "SEC27596efd776991b2f6786270fa59552459f64612b17adf377295669361af3fae";

2、配置加签

配置路径

    private String getSign() {Long timestamp = System.currentTimeMillis();String stringToSign = timestamp + "\n" + DINGDING_SECRET;Mac mac = null;String sign = null;try {mac = Mac.getInstance("HmacSHA256");mac.init(new SecretKeySpec(DINGDING_SECRET.getBytes("UTF-8"), "HmacSHA256"));byte[] signData = mac.doFinal(stringToSign.getBytes("UTF-8"));sign = URLEncoder.encode(new String(Base64.encodeBase64(signData)), "UTF-8");} catch (Exception e) {throw new IllegalArgumentException("加签处理有误");}return "&timestamp=" + timestamp + "&sign=" + sign;}

3、按照钉钉要求整理json数据结构

如果phone为null则发送普通消息，不为空则发送给特定的人

   private JSONObject buildDingDingMessage(String phone, String message) {//2、按要求配置参数格式JSONObject json = new JSONObject();json.put("msgtype", "text");json.put("text", new JSONObject() {{put("content", message);}});if (!UtilString.isBlank(phone)) {ArrayList<String> list = new ArrayList<>();list.add(phone);json.put("at", new JSONObject() {{put("atMobiles", list.toArray());}});}return json;}

    @Overridepublic void doSendMessage(String phone, String message) {//1、检查数据if (UtilString.isBlank(message)) {throw new IllegalArgumentException("请输入钉钉服务机器人要输出的信息");}//2、配置钉钉信息JSONObject  json = buildDingDingMessage(phone, message);//3、请求String url = URL + getSign();String responseText = HttpClient.textBody(url).json(json.toJSONString()).connectTimeout(60).readTimeout(5 * 60).writeTimeout(5 * 60).asString();
//无错则不发送日志消息JSONObject responseJson = JSON.parseObject(responseText);if (!responseJson.getString("errmsg").equals("ok")) {log.error(responseJson.getString("errmsg"));}}
