创建菜单时，需要将菜单内容组织成如下结构，以POST的方式向微信服务器提交。

{    "button": [        {            "name": "扫码",             "sub_button": [                {                    "type": "scancode_waitmsg",                     "name": "扫码带提示",                     "key": "rselfmenu_0_0"                },                 {                    "type": "scancode_push",                     "name": "扫码推事件",                     "key": "rselfmenu_0_1"                }            ]        },         {            "name": "发图",             "sub_button": [                {                    "type": "pic_sysphoto",                     "name": "系统拍照发图",                     "key": "rselfmenu_1_0"                },                 {                    "type": "pic_photo_or_album",                     "name": "拍照或者相册发图",                     "key": "rselfmenu_1_1"                },                 {                    "type": "pic_weixin",                     "name": "微信相册发图",                     "key": "rselfmenu_1_2"                }            ]        },         {            "name": "其他",             "sub_button": [                {                    "name": "发送位置",                     "type": "location_select",                     "key": "rselfmenu_2_0"                },                 {                    "type": "click",                     "name": "今日歌曲",                      "key": "V1001_TODAY_MUSIC"                },                 {                    "type": "view",                     "name": "搜索",                     "url": "http:// www.soso.com/"                }            ]        }    ]}  

自定义菜单内容的参数说明如表5-3所示。

表5-3　自定义菜单参数说明

为微信公众号创建自定义菜单的代码实现如下。

$jsonmenu = '{    "button": [        {            "name": "扫码",             "sub_button": [                {                    "type": "scancode_waitmsg",                     "name": "扫码带提示",                     "key": "rselfmenu_0_0"                },                 {                    "type": "scancode_push",                     "name": "扫码推事件",                     "key": "rselfmenu_0_1"                }            ]        },         {            "name": "发图",             "sub_button": [                {                    "type": "pic_sysphoto",                     "name": "系统拍照发图",                     "key": "rselfmenu_1_0"                },                 {                    "type": "pic_photo_or_album",                     "name": "拍照或者相册发图",                     "key": "rselfmenu_1_1"                },                 {                    "type": "pic_weixin",                     "name": "微信相册发图",                     "key": "rselfmenu_1_2"                }            ]        },         {            "name": "其他",             "sub_button": [                {                    "name": "发送位置",                     "type": "location_select",                     "key": "rselfmenu_2_0"                },                 {                    "type": "click",                     "name": "今日歌曲",                     "key": "V1001_TODAY_MUSIC"                },                 {                    "type": "view",                     "name": "搜索",                     "url": "http:// www.soso.com/"                }            ]        }    ]}';$url = "https:// api.weixin.qq.com/cgi-bin/menu/create?access_token=".$access_token;$result = https_request($url, $jsonmenu);var_dump($result);function https_request($url,$data = null){    $curl = curl_init;    curl_setopt($curl, CURLOPT_URL, $url);    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE);    curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, FALSE);    if (!empty($data)){        curl_setopt($curl, CURLOPT_POST, 1);        curl_setopt($curl, CURLOPT_POSTFIELDS, $data);    }    curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);    $output = curl_exec($curl);    curl_close($curl);    return $output;}  

正确时返回的JSON数据包如下。

{"errcode":0,"errmsg":"ok"}  

错误时返回的JSON数据包如下（示例为无效菜单名长度）。

{"errcode":40018,"errmsg":"invalid button name size"}  

其中，errcode为全局返回码。
