Question

我尝试使用ZF的下一个验证器：

$ isImageValidator = new Zend_Validate_File_IsImage（array（'headerCheck'=＆gt; true））;

（我不想使用fileInfo或mimeMagic）

但即使选择了图像，验证器也会返回：

文件'image.png'没有图像，检测到'application / octet-stream'

（当我查看$ _FILES全局数组时，它检测到'image / png'）为什么???

请帮帮我......

Answer 1

我的prod服务器上有同样的问题。默认情况下，作为isImage基类的Zend_Validate_File_MimeType使用一个在系统中定义mime类型的文件。

在我的情况下，这个文件是/usr/share/file/magic.mime

我刚刚删除了MimeType中列出的所有文件：

protected $_magicFiles = array(
    '/usr/share/misc/magic',
    '/usr/share/misc/magic.mime',
    '/usr/share/misc/magic.mgc',
    '/usr/share/mime/magic',
    '/usr/share/mime/magic.mime',
    '/usr/share/mime/magic.mgc',
    '/usr/share/file/magic',
    '/usr/share/file/magic.mime',
    '/usr/share/file/magic.mgc',
);

尝试：

$transfer = new Zend_File_Transfer_Adapter_Http();

// $transfer->addValidator(new Zend_Validate_File_IsImage());

$transfer->addValidator(new Zend_Validate_Callback(function($filepath, $file) use($transfer){

    $mimes = array('image/bmp',  'image/c',  'image/cgm',  'image/fif',  'image/gif',  'image/jpeg',  'image/jpm',  'image/jpx',  'image/jp2',  'image/naplps',  'image/pjpeg',  'image/png',  'image/svg',  'image/svg+xml',  'image/tiff',  'image/vnd.adobe.photoshop',  'image/vnd.djvu',  'image/vnd.fpx',  'image/vnd.net-fpx',  'image/x-cmu-raster',  'image/x-cmx',  'image/x-coreldraw',  'image/x-cpi',  'image/x-emf',  'image/x-ico',  'image/x-icon',  'image/x-jg',  'image/x-ms-bmp',  'image/x-niff',  'image/x-pict',  'image/x-pcx',  'image/x-portable-anymap',  'image/x-portable-bitmap',  'image/x-portable-greymap',  'image/x-portable-pixmap',  'image/x-quicktime',  'image/x-rgb',  'image/x-tiff',  'image/x-unknown',  'image/x-windows-bmp',  'image/x-xpmi');

    if(!in_array($file['type'], $mimes)) {

        $transfer->addError(sprintf("O arquivo não é uma imagem: '%s' detectado", $file['type']));  
        return false;
    }
    return true;
}));

验证程序Zend_Validate_File_IsImage无法正常工作
