php微信开发实现自定义菜单功能
时间：2022-04-06 13:10
首先说一下遇到的坑吧！
01我用的测试公众号，说好的有接口权限，结果呢，微信留了个坑，返回错误代码 48001
一查错误码 微信文档这样写：api功能未授权，请确认公众号已获得该接口，可以在公众平台官网-开发者中心页中查看接口权限
懵逼了吧！
半信半疑中，我果断换了认证过的服务号，一测试OK了
02代码的开头有空格也会报错，跟tp的机制有关，我的代码在tp下面。
03 调用接口的链接为https，结果我的服务器可能验证证书出错，最后找了半天才找到一种解决办法，就是在使用curl的部分使用如下代码：
可以通过添加一下代码解决
curl_setopt_array(
$ch,
array(
CURLOPT_URL => $url,
CURLOPT_REFERER => $url,
CURLOPT_AUTOREFERER => true,
CURLOPT_RETURNTRANSFER => true,
CURLOPT_SSL_VERIFYPEER => false,
CURLOPT_SSL_VERIFYHOST => false,
CURLOPT_CONNECTTIMEOUT => 1,
CURLOPT_TIMEOUT => 30,
CURLOPT_USERAGENT => ‘Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/34.0.1847.116 Safari/537.36‘,)
);
接下来就直接上代码吧！我的代码是在tp5下的代码，单独编写不方便运行，就用的tp5
我的访问路径为：http://wexin.bsgrj.com/wexin/public/index.php/index/index/definedItem
直接在浏览器运行就可以。

接下来，开发微信卡包电子会员！加油！耽误10天左右了，入了好多坑，真心累！
