一、创建账号

微信公众平台

讯享网

 注意这里是个人的，只能选择订阅号

二、配置

 这个白名单是允许获取access_token的ip由于个人公众号接口权限有限，所以很多接口也用不到。

可以申请测试账号进行开发地址：微信公众平台

我这里已经申请到账号了，所以直接用正式账号配置的。

三、代码实现

校验连接的接口

package com.wssnail.controller; import com.wssnail.service.VerifyUrlService; import com.wssnail.service.WxService; import com.wssnail.service.impl.VerifyUrlServiceImpl; import lombok.extern.slf4j.Slf4j; import org.apache.commons.lang3.StringUtils; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.RequestParam; import org.springframework.web.bind.annotation.RestController; / * @author 熟透的蜗牛 * @version 1.0 * @description: 校验连接的controller, 配置的路径和发送消息是同一个接口 * @date 2022/10/9 21:59 */ @RestController @Slf4j public class WxController { @Autowired private VerifyUrlService verifyUrlService; @Autowired private WxService wxService; / * @param signature * @param timestamp * @param nonce * @param echostr * @description: 校验链接，这个接口就是上面配置的自定义接口 * @return: java.lang.String * @author 熟透的蜗牛 * @date: 2022/10/9 22:00 */ @GetMapping(value = "/xxx/onWxMsg") public String checkWxToken(@RequestParam(value = "signature", required = true) String signature, @RequestParam(value = "timestamp", required = true) String timestamp, @RequestParam(value = "nonce", required = true) String nonce, @RequestParam(value = "echostr", required = true) String echostr) throws Exception { if (StringUtils.isNotEmpty(echostr)) { // 用于微信校验接口存在性，必须返回echostr return verifyUrlService.verifyUrl(signature, timestamp, nonce, echostr); } //返回echostr,或则success字符串，否则微信公众号识别不出来 return "success"; } / * @description: 获取access_token, 注意服务器的ip一定要加加入白名单，否则获取失败，每天获取次数有限，请自行保存这个token * @return: java.lang.String * @author 熟透的蜗牛 * @date: 2022/10/9 22:01 */ @GetMapping("/getAccessToken") public String getAccessToken() { // https://api.weixin..com/cgi-bin/token?grant_type=client_credential&appid=APPID&secret=APPSECRET return wxService.getToken(); } } 

 回复消息的接口

四、源码

wssnail-wx-office: 搭建个人微信公众号,修改配置文件为自己的appid等信息即可使用
