想要实现自定义菜单的功能,需要有已认证订阅号和已认证服务号。对于测试开发来说,可以直接申请一个测试账号:http://mp.weixin.qq.com/debug...

同样需要token的验证,前期接口已经定义好了,直接拿来就可以

根据开发者文档,自定义菜单注意:

1、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。
2、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。
3、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。

自定义菜单接口可实现多种类型按钮,如下:

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...

click和view的请求示例

 {
     "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"
            }]
       }]
 }

参数说明:

返回结果
正确时的返回JSON数据包如下:

{"errcode":0,"errmsg":"ok"}

错误时的返回JSON数据包如下(示例为无效菜单名长度):

{"errcode":40018,"errmsg":"invalid button name size"}

以上均来自官方说明文档。

如果修改了话,可以取消关注再添加关注,就能看到更改信息后的菜单信息。

对于菜单的点击事件,可以回到我们的newMessageRequest方法中添加代码:

// 自定义菜单点击事件
else if (eventType.equals(MessageUtil.EVENT_TYPE_CLICK)) {
String eventKey = requestMap.get("EventKey");// 事件KEY值,与创建自定义菜单时指定的KEY值对应
if (eventKey.equals("return_content")) {

  text.setContent("赞赞赞");
  text.setToUserName(fromUserName);
  text.setFromUserName(toUserName);
