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。
访问下面这个地址（注意替换你的appid和secret）：
https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=APPID&secret=APPSECRET
然后在浏览器能看到一下返回信息：
{"access_token":"这里就是你的access_token","expires_in":7200}
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();
