我是靠谱客的博主还单身哈密瓜，最近开发中收集的这篇文章主要介绍微信公众号菜单接口，觉得挺不错的，现在分享给大家，希望可以做个参考。

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.logging.log4j.Logger;

import java.io.IOException;

/**

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);

                httppost.setEntity(stringentity);
                httpresponse = httpclient.execute(httppost);
                response = EntityUtils

                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");
    }
