1. Check whether it is in accordance with passport

<code class="bash">composer require laravel/passport</code>

For configuration, please refer to: API authorization document

2. Modify PassportServiceProvider.php

Modify PassportServiceProvider.php

<code class="php">//将这100year的过期时间！！！！！！！超过2038

$server->enableGrantType(
    new PersonalAccessGrant, new DateInterval('P100Y')
);

//更改为1year

$server->enableGrantType(
    new PersonalAccessGrant, new DateInterval('P1Y')
);</code>

<code>4字节也就是32位的存储空间的最大值是2147483647，当时间一秒一秒地跳完2147483647那惊心动魄的最后一秒后，它就会转为负数也就是说时间无效。那一刻的准确的时间为2038年1月18日星期一晚上10时14分7秒，之后所有用到这种“标准时间库”的C语言程序都会碰到时间计算上的麻烦。</code>
