1.定义审批模板

参考https://ding-doc.dingtalk.com/doc#/serverapi2/tvu5f4
使管理员在后台的管理界面中创建一个模板，在浏览器url中查找process_code参数记录下来后面发送钉钉审批时需要用到

2.发送审批

Postman测试钉钉审批流发送

1.获取access_token
https://oapi.dingtalk.com/gettoken?appkey=appkey
&appsecret=appsecret";//在钉钉管理员后台中获取appkey和appsecret
2.发送审批申请
地址：https://oapi.dingtalk.com/topapi/processinstance/create?access_token=access_token

{"form_component_values": {"name": "详细信息",//传入为控件定义的名称，控件详细信息可看官方文档"value": "所在部门：什么部 \n 所要发布职位名称：java \n 职级:p8 \n 职位要求：会java \n 发布理由：缺人 "},//内容"dept_id": "-1",//所在部门根部门为-1"process_code": "process_code",//url中的process_code"originator_user_id": "userid"//发起人userid可以通过手机或unionid获取
}

钉钉发送请求帮助类
3.需要在maven中导入httpClient坐标

<dependency><groupId>org.apache.httpcomponents</groupId><artifactId>httpclient</artifactId><version>4.5.10</version>
</dependency>

4.帮助类代码

public class DDAuthUntil {public static JSONObject httpGet(String url){JSONObject jsonrResult = null;CloseableHttpClient closeableHttpClient = HttpClients.createDefault();HttpGet httpGet = new HttpGet(url);try {CloseableHttpResponse response = closeableHttpClient.execute(httpGet);HttpEntity entity = response.getEntity();String result = EntityUtils.toString(entity, "UTF-8");jsonrResult = JSON.parseObject(result);} catch (IOException e) {e.printStackTrace();}return jsonrResult;}public static JSONObject httpPost(String url,JSONObject json){CloseableHttpClient httpClient = HttpClients.createDefault();JSONObject jsonrResult = null;HttpPost httpPost = new HttpPost(url);try {if (null != json){StringEntity entity = new StringEntity(json.toString(),"utf-8");entity.setContentEncoding("UTF-8");entity.setContentType("application/json");httpPost.setEntity(entity);CloseableHttpResponse response = httpClient.execute(httpPost);if (response.getStatusLine().getStatusCode() == HttpStatus.SC_OK){String result =EntityUtils.toString(response.getEntity(), "utf-8");System.out.println("result:"+result);jsonrResult = JSONObject.parseObject(result);}}}catch (Exception e){e.printStackTrace();}finally {try {httpClient.close();} catch (IOException e) {e.printStackTrace();}}return jsonrResult;}//钉钉工作消息发送帮助类public static String sendMessage(String content,String mobile){try {String access_tokenUrl = "https://oapi.dingtalk.com/gettoken?appkey=dingq8p7srlitsx0xjey&appsecret=S1SzCjx3VAAAzrhCehl1UhgCu3WEygyvVWZsyl_mcpIa3R52sZz6WqvrMDBlQmcI";JSONObject access_token = DDAuthUntil.httpGet(access_tokenUrl);String accessToken = access_token.getString("access_token");String getUseridurl = "https://oapi.dingtalk.com/user/get_by_mobile?access_token="+accessToken+"&mobile="+mobile;JSONObject useridJson = DDAuthUntil.httpGet(getUseridurl);String userid = useridJson.getString("userid");//发送通知String asyncsendurl = "https://oapi.dingtalk.com/topapi/message/corpconversation/asyncsend_v2?access_token="+accessToken;JSONObject jsonObject = new JSONObject();jsonObject.put("agent_id","696435982");jsonObject.put("userid_list",userid);JSONObject msgtype = new JSONObject();msgtype.put("msgtype","text");JSONObject contents = new JSONObject();contents.put("content",content);msgtype.put("text",contents);jsonObject.put("msg",msgtype);System.out.println(jsonObject);DDAuthUntil.httpPost(asyncsendurl,jsonObject);return "发送消息成功";}catch (Exception e){e.printStackTrace();return "发送消息失败";}}
}

4.审批流发送代码
我们采用的是获取用户的钉钉手机号来获取userid
*第一个参数 mobile 为手机号，第二个参数processCode为process_code，第三个参数deptId为所在部门

//钉钉审批工作流public static void ddApproval(String mobile,String processCode,String deptId,String content){//获取accessTokenString access_tokenUrl = "https://oapi.dingtalk.com/gettoken?appkey=appkey
&appsecret=appsecret";//在钉钉管理员后台中获取appkey和appsecretJSONObject access_token = DDAuthUntil.httpGet(access_tokenUrl);String accessToken = access_token.getString("access_token");//获取useridString getUseridurl = "https://oapi.dingtalk.com/user/get_by_mobile?access_token="+accessToken+"&mobile="+mobile;JSONObject useridJson = DDAuthUntil.httpGet(getUseridurl);String userid = useridJson.getString("userid");//发起审批String createApproval = "https://oapi.dingtalk.com/topapi/processinstance/create?access_token="+accessToken;//用JSONObject封装参数JSONObject jsonObject = new JSONObject();//封装useridjsonObject.put("originator_user_id",userid);//url中的process_codejsonObject.put("process_code",processCode);//所在部门根部门为-1jsonObject.put("dept_id",deptId);//参数拼接JSONObject form_component_values = new JSONObject();//组件内容form_component_values.put("name","详细信息");form_component_values.put("value",content);jsonObject.put("form_component_values",form_component_values);System.out.println(jsonObject);DDAuthUntil.httpPost(createApproval,jsonObject);}

该方式采用的是钉钉创建默认的审批流程，如需指定审批人将approvers加入jsonObject 中

6.返回结果

{"errcode": 0,"process_instance_id": "3f2e9752-ca89-4c-b7-9,//审批流唯一代码"request_id": "6inrrnit9" 
}
