3. 添加自定义菜单 {"errcode":85005,"errmsg":"appid not bind weapp hint: [8bRFoA0823vr20]"}

这里在微信官网上用调试工具来实现， 代码实现后面再补 。

step 1、获取 access_token:

step 2:  粘贴上一步获取到的 access_token， 在 body 中粘贴：

{
     "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":"click",
               "name":"赞一下我们",
               "key":"V1001_GOOD"
            }]
       }]
 }

官方文档 https://mp.weixin.qq.com/wiki?t=resource/res_main&id=mp1421141013

中的 json 

 {
     "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"
            }]
       }]
 }

是有问题的， 会报错：

{"errcode":85005,"errmsg":"appid not bind weapp hint: [8bRFoA0823vr20]"}

删除这一块：

{ "type":"miniprogram", "name":"wxa", "url":"http://mp.weixin.qq.com", "appid":"wx286b93c14bbf93aa", "pagepath":"pages/lunar/index.html", },

才行。

不明白官方文档为什么都有坑……
