在使用微信官方给的添加自定义菜单的示例代码：
{ "button": [ { "name": "扫码", "sub_button": [ { "type": "scancode_waitmsg", "name": "扫码带提示", "key": "rselfmenu_0_0", "sub_button": [ ] }, { "type": "scancode_push", "name": "扫码推事件", "key": "rselfmenu_0_1", "sub_button": [ ] } ] }, { "name": "发图", "sub_button": [ { "type": "pic_sysphoto", "name": "系统拍照发图", "key": "rselfmenu_1_0", "sub_button": [ ] }, { "type": "pic_photo_or_album", "name": "拍照或者相册发图", "key": "rselfmenu_1_1", "sub_button": [ ] }, { "type": "pic_weixin", "name": "微信相册发图", "key": "rselfmenu_1_2", "sub_button": [ ] } ] }, { "name": "发送位置", "type": "location_select", "key": "rselfmenu_2_0" }, { "type": "media_id", "name": "图片", "media_id": "MEDIA_ID1" }, { "type": "view_limited", "name": "图文消息", "media_id": "MEDIA_ID2" } ]}
可能会遇到如下的错误：
Connection: keep-aliveDate: Sat, 24 Nov 2018 00:58:30 GMTContent-Type: application/json; encoding=utf-8Content-Length: 71{ "errcode": 40016, "errmsg": "invalid button size hint: [dNjLEa01101961]"}
原因可能是因为想展示的按钮太多了，装不下了，去掉最后两个就好了：
{ "button": [ { "name": "扫码", "sub_button": [ { "type": "scancode_waitmsg", "name": "扫码带提示", "key": "rselfmenu_0_0", "sub_button": [ ] }, { "type": "scancode_push", "name": "扫码推事件", "key": "rselfmenu_0_1", "sub_button": [ ] } ] }, { "name": "发图", "sub_button": [ { "type": "pic_sysphoto", "name": "系统拍照发图", "key": "rselfmenu_1_0", "sub_button": [ ] }, { "type": "pic_photo_or_album", "name": "拍照或者相册发图", "key": "rselfmenu_1_1", "sub_button": [ ] }, { "type": "pic_weixin", "name": "微信相册发图", "key": "rselfmenu_1_2", "sub_button": [ ] } ] }, { "name": "发送位置", "type": "location_select", "key": "rselfmenu_2_0" } ]}
