在使用微信官方给的添加自定义菜单的示例代码：
{
"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"
}]
}]
}可能会遇到如下的错误：
Connection: keep-alive
Date: Sun, 14 Jan 2018 17:50:18 GMT
Content-Type: application/json; encoding=utf-8
Content-Length: 72
{
"errcode": 85005,
"errmsg": "appid not bind weapp hint: []"
}
原因出在小程序的链接上，官方只是给了个例子教你如何添加小程序链接到菜单栏，但是这个小程序并不是归属于你的，所以错误提示说appid没有绑定，这里的appid是小程序的，当然没有和你的绑定，所以只要将这段整个删掉就好了：
{
"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"
}
]
}
]
}
