大家好，我是 V 哥。最近的一个项目中，用到企业微信的审批流程，整理出来分享给大家。在企业微信中实现审批流程可以通过调用企业微信的开放API完成，企业微信提供了审批应用接口，用于创建审批模板、发起审批流程以及获取审批实例详情。下面 V 哥用一个Java示例代码，来展示如何在企业微信中实现审批流程。

实现步骤

获取企业微信Access Token：每次访问企业微信API接口前需要先获取Access Token。
创建审批模板（如已有模板则跳过此步骤）。
发起审批流程：通过指定的模板ID发起审批请求。
查询审批结果：获取审批的状态和详细信息。

以下代码使用HttpClient发起HTTP请求来调用企业微信API接口。

代码示例

import org.apache.http.client.methods.CloseableHttpResponse;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.util.EntityUtils;
import com.fasterxml.jackson.databind.ObjectMapper;
import java.io.IOException;
import java.util.HashMap;
import java.util.Map;public class WeChatApproval {//下面三个常量定义，需要用你自己的（企业微信开放平台）private static final String CORP_ID = "你的corp_id";private static final String CORP_SECRET = "你的corp_secret";private static final String APPROVAL_TEMPLATE_ID = "你的template_id"; // 审批模板ID// 获取 Access Tokenpublic static String getAccessToken() throws IOException {String url = "https://qyapi.weixin.qq.com/cgi-bin/gettoken?corpid=" + CORP_ID + "&corpsecret=" + CORP_SECRET;try (CloseableHttpClient client = HttpClients.createDefault()) {HttpGet request = new HttpGet(url);try (CloseableHttpResponse response = client.execute(request)) {String responseBody = EntityUtils.toString(response.getEntity());Map<String, Object> map = new ObjectMapper().readValue(responseBody, Map.class);return map.get("access_token").toString();}}}// 发起审批流程public static String initiateApproval(String accessToken, Map<String, Object> approvalData) throws IOException {String url = "https://qyapi.weixin.qq.com/cgi-bin/oa/applyevent?access_token=" + accessToken;try (CloseableHttpClient client = HttpClients.createDefault()) {HttpPost post = new HttpPost(url);post.setHeader("Content-Type", "application/json");Map<String, Object> requestMap = new HashMap<>();requestMap.put("template_id", APPROVAL_TEMPLATE_ID);requestMap.put("use_template_approver", 1); // 使用模板中的审批人requestMap.put("approver", approvalData.get("approver"));requestMap.put("apply_data", approvalData.get("apply_data"));requestMap.put("summary_list", approvalData.get("summary_list"));String json = new ObjectMapper().writeValueAsString(requestMap);post.setEntity(new StringEntity(json, "UTF-8"));try (CloseableHttpResponse response = client.execute(post)) {String responseBody = EntityUtils.toString(response.getEntity());Map<String, Object> map = new ObjectMapper().readValue(responseBody, Map.class);return map.get("sp_no").toString(); // 返回审批单编号}}}// 查询审批流程状态public static Map<String, Object> getApprovalDetail(String accessToken, String spNo) throws IOException {String url = "https://qyapi.weixin.qq.com/cgi-bin/oa/getapprovaldetail?access_token=" + accessToken;try (CloseableHttpClient client = HttpClients.createDefault()) {HttpPost post = new HttpPost(url);post.setHeader("Content-Type", "application/json");Map<String, Object> requestMap = new HashMap<>();requestMap.put("sp_no", spNo);String json = new ObjectMapper().writeValueAsString(requestMap);post.setEntity(new StringEntity(json, "UTF-8"));try (CloseableHttpResponse response = client.execute(post)) {String responseBody = EntityUtils.toString(response.getEntity());return new ObjectMapper().readValue(responseBody, Map.class);}}}public static void main(String[] args) {try {// 1. 获取Access TokenString accessToken = getAccessToken();System.out.println("Access Token: " + accessToken);// 2. 发起审批流程Map<String, Object> approvalData = new HashMap<>();approvalData.put("approver", new Object[] { Map.of("attr", 1, "userid", new String[] { "approver_userid" }) });approvalData.put("apply_data", Map.of("contents", new Object[] {Map.of("control", "Text", "id", "Text-1", "value", Map.of("text", "请假事由")),Map.of("control", "Date", "id", "Date-1", "value", Map.of("date", "2024-11-01"))}));approvalData.put("summary_list", new Object[] {Map.of("summary_info", Map.of("text", "请假申请"))});String spNo = initiateApproval(accessToken, approvalData);System.out.println("审批单号: " + spNo);// 3. 查询审批状态Map<String, Object> approvalDetail = getApprovalDetail(accessToken, spNo);System.out.println("审批详情: " + approvalDetail);} catch (IOException e) {e.printStackTrace();}}
}

代码说明

获取Access Token：通过getAccessToken方法获取企业微信的access_token，用于后续接口调用。
发起审批流程：initiateApproval方法通过oa/applyevent接口发起审批流程，传入审批模板ID和审批表单数据（如审批人、申请数据和摘要等）。
查询审批流程状态：getApprovalDetail方法通过oa/getapprovaldetail接口查询审批详情，包括审批状态和各环节的处理结果。
