二、java实战

2.1. 入口

  // 1.通过corpId获取AccessTokenString accessToken = getAccessToken(corpId);

2.2. 核心方法

 /*** 通过corpId获取AccessToken** @param corpId 企业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);//获取错误日志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;/*** 企业微信常量配置类** @author gblfy* @date 2022-01-12*/
public class QywxInnerConfig {public static final String BASE_URL = "https://qyapi.weixin.qq.com/cgi-bin/";//获取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 工具类
