微信公众平台开发教程(二)_微信自定义菜单的创建

3.微信自定义菜单的创建

自定义菜单接口可实现多种类型按钮,这里主要介绍如下两种:

1、click:点击推事件用户点击click类型按钮后,微信服务器会通过消息接口推送消息类型为event的结构给开发者(参考消息接口指南),并且带上按钮中开发者填写的key值,开发者可以通过自定义的key值与用户进行交互;
2、view:跳转URL用户点击view类型按钮后,微信客户端将会打开开发者在按钮中填写的网页URL,可与网页授权获取用户基本信息接口结合,获得用户基本信息。

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

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"
            }]
       }]
 }
具体代码实现,这里主要贴出拼装上述代码节点的代码,发送请求方式可以看看我之前的博客,通过HttpsURLConnection发送post请求。
