php微信开发自定义菜单

目前微信服务号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。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。请注意，创建自定义菜单后，由于微信客户端缓存，需要24小时微信客户端才会展现出来。建议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。 

目前自定义菜单接口可实现两种类型按钮，如下：
 click：
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；
view：
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url值 （即网页链接），达到打开网页的目的，建议与网页授权获取用户基本信息接口结合，获得用户的登入个人信息。 

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 
请求示例（JSON数据请使用UTF-8编码）

 {
 "button":[
  {"type":"click","name":"我的信息","sub_button":[
   {"type":"click","name":"拇指查询","key":"BUTTON_1"},
  {"type":"click","name":"拇指请假","key":"BUTTON_2"},
  {"type":"view","name":"工号绑定","url":"http://XXXXXXXXXXXXXXXXX"}]
 },
  {"type":"click","name":"业务流程","key":"BUTTON_3"},
  {"name":"员工建议","sub_button":[
   {"type":"view","name":"思想火花","url":"http://XXXXXXXXXXXXXXXXXX"},
   {"type":"view","name":"奖品兑换","url":"http://XXXXXXXXXXXXXXXXXX"},
   {"type":"click","name":"赞一下我们","key":"BUTTON_ZAN"}]
  }
 ]
}

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"} 

以下是示例代码（PHP）。

自定义菜单查询 

使用接口创建自定义菜单后，开发者还可使用接口查询自定义菜单的结构。 

请求说明
 http请求方式：GET
https://api.weixin.qq.com/cgi-bin/menu/get?access_token=ACCESS_TOKEN

 返回说明
 对应创建接口，正确的Json返回结果:  

{"menu":{"button":[{"name":"我的信息","sub_button":[{"type":"click","name":"拇指查询","key":"BUTTON_1","sub_button":[]},{"type":"click","name":"拇指请假","key":"BUTTON_2","sub_button":[]},{"type":"view","name":"工号绑定","url":"http:\/\/XXXXXXXX","sub_button":[]}]},{"type":"click","name":"业务流程","key":"BUTTON_3","sub_button":[]},{"name":"员工建议","sub_button":[{"type":"view","name":"思想火花","url":"http:\/\/XXXXXXXX","sub_button":[]},{"type":"view","name":"奖品兑换","url":"http:\/\/XXXXXXXX","sub_button":[]},{"type":"click","name":"赞一下我们","key":"BUTTON_ZAN","sub_button":[]}]}]}}

自定义菜单删除 

使用接口创建自定义菜单后，开发者还可使用接口删除当前使用的自定义菜单。 

请求说明
http请求方式：GET
https://api.weixin.qq.com/cgi-bin/menu/delete?access_token=ACCESS_TOKEN

返回说明
 对应创建接口，正确的Json返回结果:
