一、快速入門

1. 開發(fā)文檔

企業(yè)內部開發(fā)文檔：
https://developer.work.weixin.qq.com/document/path/91039

2. 管控臺

企業(yè)微信管控臺：
https://work.weixin.qq.com/wework_admin/frame#apps

3. 接口文檔

獲取access_token接口文檔

4. 參數獲取

corpid->獲取企業(yè)ID

corpsecret->應用secret

5. api調試

• postman調試
  
• 官網調試
  https://developer.work.weixin.qq.com/resource/devtool
  

二、java實戰(zhàn)

2.1. 入口

// 1.通過corpId獲取AccessTokenString accessToken = getAccessToken(corpId);

2.2. 核心方法

/*** 通過corpId獲取AccessToken** @param corpId 企業(yè)ID* @return*/public String getAccessToken(String corpId) {String result = "";String accessTokenUrl = String.format(QywxInnerConfig.ACCESS_TOKEN_URL, corpId, AGENT_SECRET);Map response = RestUtils.get(accessTokenUrl);//獲取錯誤日志if (response.containsKey("errcode") && (Integer) response.get("errcode") != 0) {logger.error(response.toString());} else {result = (String) response.get("access_token");}return result;}

2.3. 核心配置

package com.gblfy.qywxin.config;/*** 企業(yè)微信常量配置類** @author gblfy* @date 2022-01-12*/ public class QywxInnerConfig {public static final String BASE_URL = "https://qyapi.weixin.qq.com/cgi-bin/";//獲取access_token//https://open.work.weixin.qq.com/api/doc/90000/90135/91039public static final String ACCESS_TOKEN_URL = BASE_URL + "gettoken?corpid=%s&corpsecret=%s"; } @Value("${qywx.agentSecret}")private String AGENT_SECRET;

2.3. RestUtils 工具類

package com.gblfy.qywxin.utils;import com.alibaba.fastjson.JSONObject; import org.springframework.context.annotation.Configuration; import org.springframework.http.*; import org.springframework.util.MultiValueMap; import org.springframework.web.client.RestTemplate; import org.springframework.web.util.UriComponentsBuilder;import java.io.IOException; import java.net.URI; import java.nio.file.Files; import java.nio.file.Paths; import java.util.Map; import java.util.Objects;@Configuration public class RestUtils {private static final RestTemplate restTemplate = new RestTemplate();public static JSONObject get(String url, Map<String,String> urlParams){return get(urlToUri(url,urlParams));}//在處理企業(yè)微信某些參數時有問題public static JSONObject get(String url){return get(URI.create(url));}private static JSONObject get(URI uri){ResponseEntity<JSONObject> responseEntity =restTemplate.getForEntity(uri,JSONObject.class);serverIsRight(responseEntity); //判斷服務器返回狀態(tài)碼return responseEntity.getBody();}public static JSONObject post(String url,Map<String,String> urlParams,JSONObject json){//組裝urlreturn post(urlToUri(url,urlParams),json);}public static JSONObject post(String url,JSONObject json){//組裝urLreturn post(URI.create(url),json);}private static JSONObject post(URI uri,JSONObject json){//組裝url//設置提交json格式數據HttpHeaders headers = new HttpHeaders();headers.setContentType(MediaType.APPLICATION_JSON);HttpEntity<JSONObject> request = new HttpEntity(json, headers);ResponseEntity<JSONObject> responseEntity = restTemplate.postForEntity(uri,request,JSONObject.class);serverIsRight(responseEntity); //判斷服務器返回狀態(tài)碼return responseEntity.getBody();}private static URI urlToUri(String url,Map<String,String> urlParams){//設置提交json格式數據UriComponentsBuilder uriBuilder = UriComponentsBuilder.fromHttpUrl(url);for(Map.Entry<String,String> entry : urlParams.entrySet()) {uriBuilder.queryParam((String)entry.getKey(), (String) entry.getValue()) ;}return uriBuilder.build(true).toUri();}public static JSONObject upload(String url,MultiValueMap formParams){//設置表單提交HttpHeaders headers = new HttpHeaders();headers.setContentType(MediaType.MULTIPART_FORM_DATA);HttpEntity<MultiValueMap<String, String>> request = new HttpEntity<>(formParams, headers);ResponseEntity<JSONObject> responseEntity = restTemplate.postForEntity(url,request,JSONObject.class);serverIsRight(responseEntity); //判斷服務器返回狀態(tài)碼return responseEntity.getBody();}public static String download(String url,String targetPath) throws IOException {ResponseEntity<byte[]> rsp = restTemplate.getForEntity(url, byte[].class);if(rsp.getStatusCode() != HttpStatus.OK){System.out.println("文件下載請求結果狀態(tài)碼：" + rsp.getStatusCode());}// 將下載下來的文件內容保存到本地Files.write(Paths.get(targetPath), Objects.requireNonNull(rsp.getBody()));return targetPath;}public static byte[] dowload(String url){ResponseEntity<byte[]> rsp = restTemplate.getForEntity(url, byte[].class);return rsp.getBody();}private static void serverIsRight(ResponseEntity responseEntity){if(responseEntity.getStatusCodeValue()==200){ // System.out.println("服務器請求成功：{}"+responseEntity.getStatusCodeValue());}else {System.out.println("服務器請求異常：{}"+responseEntity.getStatusCodeValue());}} }

2.5. token緩存策略

建議使用redis，說一下具體實現流程：

• 1.獲取token，根據token_key 查詢redis中是否存在
• 2.如果存在，就獲取token直接用
• 3.如果不存在，則通過企業(yè)ID獲取token存儲redis過期時間設置為2小時

三、源碼分享

3.1. 后端源碼

3.2. 前端源碼

前端：https://gitee.com/gblfy/qywx-vuejs
