1. 获取栏目列表（代码弃用）
   抓包获取各栏目列表

<?php
    function url_safe_base64_encode($string) 
    { 
    $data = base64_encode($string); 
    $data = str_replace("=", "", $data); 
    return $data; 
    } 
    function encode(string $payload, string $key, string $alg = 'SHA256')
    {
        $key = md5($key);
        $head = '{"alg":"HS256"}';
        $jwt = url_safe_base64_encode($head) . '.' .url_safe_base64_encode($payload);
        return $jwt . '.' . signature($jwt, $key, $alg);
    }
   function signature(string $input, string $key, string $alg)
    {
        return hash_hmac($alg, $input, $key);
    }
$s = '{"sub":"{\"code\":\"waihui\",\"system\":\"android\",\"version\":\"6.2.7\"}"}';
$key = 'kuaixun56pslui*!@~^jhk';
echo encode($s, $key);
