微信创建菜单

先上效果图

这个是我自定义的菜单，在微信开发者文档中需要用到https协议进行更改，且更改次数有限制，如下
接口名称频率限制获取凭证接口200(次/天)
自定义菜单创建接口100(次/天)
自定义菜单查询接口1000(次/天)
自定义菜单删除接口100(次/天)
了解完上述需要注意到的实例后，接下我们在来看看创建接口时所需要的参数，如图所示：

一般的请求格式如下代码所示：

{
     "button":[
     {  
          "type":"click",
          "name":"今日歌曲",
          "key":"V1001_TODAY_MUSIC"
      },
      {
           "name":"菜单",
           "sub_button":[
           {    
               "type":"view",
               "name":"搜索",
               "url":"http://www.soso.com/"
            },
            {
                 "type":"miniprogram",
                 "name":"wxa",
                 "url":"http://mp.weixin.qq.com",
                 "appid":"wx286b93c14bbf93aa",
                 "pagepath":"pages/lunar/index"
             },
            {
               "type":"click",
               "name":"赞一下我们",
               "key":"V1001_GOOD"
            }]
       }]
 }

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
以上实现的是一个二级菜单，点击按钮跳转页面的功能，接下来我们来看看代码怎么实现。

创建菜单

public static void createMenu(String appId,String appSecret) {
        // 调用接口获取access_token
        AccessToken at = WeixinUtil.getAccessToken(appId, appSecret);

        if (null != at) {
            // 调用接口创建菜单
            int result = WeixinUtil.createMenu(getMenu(), at.getToken());

            // 判断菜单创建结果
            if (0 == result)
                System.out.print("菜单创建成功！");
            else
                System.out.print("菜单创建失败，错误码：" + result);
        }

        String jsonMenu = JSONObject.toJSONString(getMenu());
        System.out.print(jsonMenu);
    }

    private static Button getMenu() {

        String APPID = "填你自己的";
        String REDIRECT_URI = "http://rpaize.natappfree.cc/WeChatProject/wechat/hello";
        String urlscope = "snsapi_userinfo";
        String state = "1";

        BaseButton btn11 = new BaseButton();
        btn11.setName("学霸笔记本");
        btn11.setType("click");
        btn11.setKey("11");

        BaseButton btn12 = new BaseButton();
        btn12.setName("记忆宫殿");
        btn12.setType("click");
        btn12.setKey("12");

        BaseButton btn13 = new BaseButton();
        btn13.setName("逻辑思维");
        btn13.setType("view");

        StringBuilder url = new StringBuilder();
        url.append("https://open.weixin.qq.com/connect/oauth2/authorize?");
        url.append("appid="+APPID);
        url.append("&");
        url.append("redirect_uri="+REDIRECT_URI);
        url.append("&");
        url.append("response_type=code");
        url.append("&");
        url.append("scope="+urlscope);
        url.append("&state=1#wechat_redirect");
        btn13.setUrl(url.toString());

        Sub_Button sub1 = new Sub_Button();
        sub1.setName("菜单一");
        sub1.getSub_button().add(btn11);

        Sub_Button sub2 = new Sub_Button();
        sub2.setName("菜单二");
        sub2.getSub_button().add(btn12);

        Sub_Button sub3 = new Sub_Button();
        sub3.setName("xinbuxing");
        sub3.getSub_button().add(btn13);


        Button menu = new Button();
        menu.getButton().add(sub1);
        menu.getButton().add(sub2);
        menu.getButton().add(sub3);

        return  menu;
    }

接着只要在我们的main方法中跑一跑，再重新关注一下就可以了，注意我用的是测试号，订阅号好像没用开放这个权限
