$rules = array('title' => 'required', 'thumbnail' => 'image|size:500');
$inputs = array('title' => $this->title, 'thumbnail' => $this->thumbnail,);
$validator = Validator::make($inputs, $rules);
if ($validator->fails()) {
}
如果我删除'thumbnail'，它可以工作，但如果它在那里，它会在执行$validator->fails() 时崩溃
【问题讨论】：
Failed to load magic database 消息是 PHP 错误消息，与 Laravel 无关。
你的 libmagic 安装有问题，或者根本没有安装。
http://php.net/manual/en/ref.fileinfo.php
PHP Warning: finfo::finfo(): Failed to load magic database at '/etc/magic'
PHP Warning: finfo::file(): The invalid fileinfo object
These errors can be rectified by copying your magic database (depending on your distro, this file can be anywhere, on debian it's in /usr/share/file/magic) to /etc/magic.mime
libmagic automatically appends the .mime to the end of the filename, so PHP incorrectly reports the path it was looking for.
The same applies for:
PHP Warning: finfo::finfo(): Failed to load magic database at '/etc/magic.mime'
Unfortunately users will have to call the magic file /etc/magic.mime.mime in this case.
