文章目录 1、实现效果2、注意事项3、实现步骤4、代码实现（主菜）前端页面工具类accesstoken获取获取公众号菜单保存公众号菜单

1、实现效果

目前仅支持自定义菜单名称、增减菜单、外链设置，暂无图文信息在这里插入图片描述

2、注意事项自定义菜单最多包括3个一级菜单，每个一级菜单最多包含5个二级菜单。一级菜单最多4个汉字，二级菜单最多7个汉字，多出来的部分将会以“…”代替。创建自定义菜单后，菜单的刷新策略是，在用户进入公众号会话页或公众号profile页时，如果发现上一次拉取菜单的请求在5分钟以前，就会拉取一下菜单，如果菜单有更新，就会刷新客户端的菜单。测试时可以尝试取消关注公众账号后再次关注，则可以看到创建后的效果。 3、实现步骤

0）、参考官方文档：https://developers.weixin.qq.com/doc/offiaccount/Custom_Menus/Creating_Custom-Defined_Menu.html

1）、搞一套前端代码

2）、获取公众号菜单

接口调用请求说明

http请求方式: GET（请使用https协议）

https://api.weixin.qq.com/cgi-bin/get_current_selfmenu_info?access_token=ACCESS_TOKEN

3）、保存公众号菜单

接口调用请求说明

http请求方式：POST（请使用https协议）

https://api.weixin.qq.com/cgi-bin/menu/create?access_token=ACCESS_TOKEN

4、代码实现（主菜）前端页面

工具类 package com.wf.commons.utils; import net.sf.json.JSONObject; import org.apache.http.HttpEntity; import org.apache.http.HttpResponse; import org.apache.http.clienthods.CloseableHttpResponse; import org.apache.http.clienthods.HttpGet; import org.apache.http.clienthods.HttpPost; import org.apache.http.entity.ContentType; import org.apache.http.entity.StringEntity; import org.apache.http.impl.client.CloseableHttpClient; import org.apache.http.impl.client.DefaultHttpClient; import org.apache.http.impl.client.HttpClients; import org.apache.http.util.EntityUtils; import org.apache.logging.log4j.LogManager; import org.apache.logging.log4j.Logger; import java.io.IOException; /** * Created by wanter on 2019/10/9. * 后端模拟请求 */ public class AuthUtil { private static final Logger LOGGER = LogManager.getLogger(AuthUtil.class); public static JSONObject doGetJson(String url) throws IOException { JSONObject jsonObject = null; DefaultHttpClient client = new DefaultHttpClient(); HttpGet httpGet = new HttpGet(url); HttpResponse response = client.execute(httpGet); HttpEntity entity = response.getEntity(); if (entity != null) { String result = EntityUtils.toString(entity, "UTF-8"); jsonObject = JSONObject.fromObject(result); } httpGet.releaseConnection(); return jsonObject; } //post请求方法 public static String sendPost(String url, String menu) { String response = null; LOGGER.info("url: " + url); LOGGER.info("request: " + menu); try { CloseableHttpClient httpclient = null; CloseableHttpResponse httpresponse = null; try { httpclient = HttpClients.createDefault(); HttpPost httppost = new HttpPost(url); StringEntity stringentity = new StringEntity(menu, ContentType.create("text/json", "UTF-8")); httppost.setEntity(stringentity); httpresponse = httpclient.execute(httppost); response = EntityUtils .toString(httpresponse.getEntity()); LOGGER.info("response: " + response); } finally { if (httpclient != null) { httpclient.close(); } if (httpresponse != null) { httpresponse.close(); } } } catch (Exception e) { e.printStackTrace(); } return response; } } accesstoken获取

如果accesstoken获取失败很可能是因为没有设置服务器白名单，公众号绑定了域名，获取accesstoken需要在服务器上调试，本地不知道怎么测试，哪位大神知道可以给我留言，谢谢。

package com.wf.commons.utils.wechat; import com.wf.commons.utils.AuthUtil; import com.wf.commons.utils.WeixinUtil; import com.wf.mobile.model.AccessToken; import net.sf.json.JSONObject; import java.io.IOException; /** * Created by wanter on 2019/10/16. */ public class AccessTokenTool { //自己的appid 和 appsecret private static final String APPID = WeixinUtil.APPID; private static final String APPSECRET = WeixinUtil.APPSECRET; //用于存储token private static AccessToken at; /** * @return * @throws Exception */ private static AccessToken getAccessToken() throws IOException { String accessTokenUrl = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=APPID&secret=APPSECRET"; accessTokenUrl = accessTokenUrl.replace("APPID", APPID).replace("APPSECRET", APPSECRET); System.out.println(" 微信全局token的url " + accessTokenUrl); JSONObject jsonObject = AuthUtil.doGetJson(accessTokenUrl); System.out.println(" jsonObject " + jsonObject); /** * 获取access_token * 成功返回的json : {"access_token":"ACCESS_TOKEN","expires_in":7200} * 失败放的json : {"errcode":40013,"errmsg":"invalid appid"} * */ String accessToken = jsonObject.getString("access_token"); String expires_in = jsonObject.getString("expires_in"); System.out.println("accessToken = " + accessToken); System.out.println("expires_in = " + expires_in); if (!jsonObject.containsKey("errcode")) { //创建token，并且存起来 at = new AccessToken(expires_in, accessToken); return at; } return null; } /** * 对外提供获取 AccessTokenTool * * @return */ public static String getToken() { if (at == null || at.isExpired() == true) { //logger.info("过期"); try { getAccessToken(); } catch (Exception e) { e.printStackTrace(); } } return at.getAccess_token(); } } 获取公众号菜单

当前action的请求路径需要与前端请求路径一致

@PostMapping("/getButton") @ResponseBody public Object getButton() throws IOException { Subject subject = SecurityUtils.getSubject(); if (subject != null) { ShiroUser user = (ShiroUser) subject.getPrincipal(); if (user != null) { String basetoken = AccessTokenTool.getToken(); System.out.println("#########tooken"+basetoken+"#########"); //根据token获取数据 String getUrl = "https://api.weixin.qq.com/cgi-bin/get_current_selfmenu_info?access_token="+basetoken; JSONObject doGetJson = AuthUtil.doGetJson(getUrl); System.out.println("#########doGetJson"+doGetJson+"#########"); return doGetJson; } else { return renderError("请先登录后再获取"); } }else { return renderError("请先登录后再获取"); } } 保存公众号菜单 @PostMapping("saveButton") @ResponseBody public Object saveButton(String menujson) { Subject subject = SecurityUtils.getSubject(); if (subject != null) { ShiroUser user = (ShiroUser) subject.getPrincipal(); if (user != null) { String basetoken = AccessTokenTool.getToken(); String postUrl = " https://api.weixin.qq.com/cgi-bin/menu/create?access_token=" + basetoken; URL url = null;//把string类型先转化为URL类型 try { url = new URL(postUrl); URI uri = url.toURI(); String rs = AuthUtil.sendPost(uri.toString(), menujson); System.out.println(rs); return rs; } catch (MalformedURLException e) { e.printStackTrace(); } catch (URISyntaxException e) { e.printStackTrace(); } } else { return renderError("请先登录后再设置"); } } else { return renderError("请先登录后再设置"); } return renderError("请先登录后再设置"); }
