微信开发笔记：修改公众号自定义菜单

在使用通用接口前，你需要做以下两步工作：
1.拥有一个微信公众账号，并获取到appid和appsecret（在公众平台申请内测资格，审核通过后可获得）
2.通过获取凭证接口获取到access_token
注意：
access_token是第三方访问api资源的票据；
access_token对应于公众号是全局唯一的票据，重复获取将导致上次获取的access_token失效。

创建自定义菜单：

<?php
header("Content-type: text/html; charset=utf-8");
define("ACCESS_TOKEN", "这里填入你上面获取到的access_token");


//创建菜单
function createMenu($data){
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://api.weixin.qq.com/cgi-bin/menu/create?access_token=".ACCESS_TOKEN);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (compatible; MSIE 5.01; Windows NT 5.0)');
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_AUTOREFERER, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$tmpInfo = curl_exec($ch);
if (curl_errno($ch)) {
  return curl_error($ch);
}

curl_close($ch);
return $tmpInfo;

}

//获取菜单
function getMenu(){
return file_get_contents("https://api.weixin.qq.com/cgi-bin/menu/get?access_token=".ACCESS_TOKEN);
}

//删除菜单
function deleteMenu(){
return file_get_contents("https://api.weixin.qq.com/cgi-bin/menu/delete?access_token=".ACCESS_TOKEN);
}





$data = '{
     "button":[
     {
          "type":"click",
          "name":"首页",
          "key":"home"
      },
      {
           "type":"click",
           "name":"简介",
           "key":"introduct"
      },
      {
           "name":"菜单",
           "sub_button":[
            {
               "type":"click",
               "name":"hello word",
               "key":"V1001_HELLO_WORLD"
            },
            {
               "type":"click",
               "name":"赞一下我们",
               "key":"V1001_GOOD"
            }]
       }]
}';




echo createMenu($data);
//echo getMenu();
//echo deleteMenu();
