钉钉消息推送

钉钉消息推送

进入钉钉开放平台，找到应用开发–>企业内部开发

获取到重要的三个参数

AgentId，AppKey，AppSecret

其次就是开启权限

一般是全部员工，然后，你想调用那个接口就申请那个权限。如果你不知道申请那个权限可以再他的官方文档里找，那里有提示。

因为这里是做的发送消息通知，那么就需要通讯录的权限，找到通讯录，把需要的都选了。

开发准备

引入dingtalk和alibaba-dingtalk-service-sdk

第一步获取access_token

dingtalk:    #钉钉--消息通知 
    agentId: xxxxxxxx
    appKey: xxxxxxxxxxxx
    appSecret: xxxxxxxxxxxx

工具类

    // 调用httpGet方法获得access_token的代码实现：
    public static String getAccess_Token(String appkey, String appsecret) {
        String url = "https://oapi.dingtalk.com/gettoken?" + "appkey=" + appkey + "&appsecret=" + appsecret;
        JSONObject res = HttpHelper.httpGet(url);
        String access_token = "";
        if (res != null) {
            access_token = res.getString("access_token");
        } else {
            new Exception("获取token异常");
        }
        return access_token;
    }

第二步根据这个access_token就是获得了对应的接口凭证，现在根据api

DingTalkClient client2 = new DefaultDingTalkClient("https://oapi.dingtalk.com/user/get_by_mobile");

第三步根据req, accessToken去请求urid

  OapiUserGetByMobileRequest req = new OapiUserGetByMobileRequest();
            req.setMobile(mobile);
            req.setHttpMethod("GET");
            //根据req, accessToken去请求urid
            OapiUserGetByMobileResponse rsp = client2.execute(req, accessToken);
            //获取到Urid就是在公司里要发送到那个人的id
            String urid = rsp.getUserid();

第四步根据用户id获取用户详情

            //根据用户id获取用户详情
            DingTalkClient userDetail = new DefaultDingTalkClient("https://oapi.dingtalk.com/user/get");
            OapiUserGetRequest userReq = new OapiUserGetRequest();
            userReq.setUserid(urid);
            userReq.setHttpMethod("GET");
            OapiUserGetResponse userRsp = userDetail.execute(userReq, accessToken);
            String userName = userRsp.getName();

第五步发送消息

DingTalkClient client = new DefaultDingTalkClient("https://oapi.dingtalk.com/topapi/message/corpconversation/asyncsend_v2");
OapiMessageCorpconversationAsyncsendV2Request request = new OapiMessageCorpconversationAsyncsendV2Request();
request.setUseridList(urid);
request.setAgentId(Long.valueOf(agentId));
request.setToAllUser(false);

第六步设置消息类型（OA）

OapiMessageCorpconversationAsyncsendV2Request.Msg msg = new OapiMessageCorpconversationAsyncsendV2Request.Msg();
msg.setOa(new OapiMessageCorpconversationAsyncsendV2Request.OA());

第七步消息体

        //设置head
            msg.getOa().setHead(new OapiMessageCorpconversationAsyncsendV2Request.Head());
            msg.getOa().getHead().setText("待办事宜");
            msg.getOa().getHead().setBgcolor("00409eff");
            //设置body
            msg.getOa().setBody(new OapiMessageCorpconversationAsyncsendV2Request.Body());
            msg.getOa().getBody().setTitle("尊敬的 " + userName + "(项目经理)");
            msg.getOa().getBody().setContent("待审批:"+sendMsg+"条"+"\n创建时间：" + sdf.format(new Date())+"");

            //消息类型
            msg.setMsgtype("oa");
            request.setMsg(msg);
            log.info("获取发送通知消息体和获取发送通知人完成");
            OapiMessageCorpconversationAsyncsendV2Response response = client.execute(request,accessToken);
            log.info("发送消息是否成功"+response.isSuccess());
            System.out.println(response.isSuccess());
            log.info("消息任务ID"+response.getTaskId());
            System.out.println(response.getTaskId());

s());
log.info(“消息任务ID”+response.getTaskId());
System.out.println(response.getTaskId());
