文件校验规则 — 对齐 PHP Driver::validatefileSize/fileExt/fileMime 规则

PHP 原始规则(app/common/library/storage/Driver.php 第 29-33 行):

validate([$name=>[
    'fileSize' => 20971520,
    'fileExt' => 'jpg,jpeg,png,gif,bmp',
    'fileMime' => 'image/jpeg,image/png,image/gif,image/bmp',
]])

§字段语义

  • file_sizeNone 表示不校验大小(对齐 PHP 未设置 fileSize 规则)
  • file_extNone 表示不校验扩展名
  • file_mimeNone 表示不校验 MIME

Fields§

§file_size: Option<u64>

最大文件大小(字节),None 表示不校验

§file_ext: Option<Vec<String>>

扩展名白名单(小写),None 表示不校验

§file_mime: Option<Vec<String>>

MIME 白名单(小写),None 表示不校验
