所以我试图从我的服务器重定向所有图像请求以使用自定义PHP脚本。 PHP脚本内置在一个可以通过http://www.domain.com/images/imageNameHere.jpg访问的框架中。用户显然不知道图像是否正在向他们提供。所以现在问题是这个方法目前正在为它的顶级工作,但对于后端它会导致很多问题。例如,如果我尝试在此图像上使用另一个PHP函数(如getimagesize()),则返回错误,无法打开该流。
进一步研究这个问题,我注意到这些图像的所有标题都生成了404未找到的错误。 (通过在线使用标题检测工具找到这一点,然后在error_log中看到每个加载的图像都会出现404未找到的错误)不用说我不能拥有这个,我需要所有的请求都是200的。我觉得这样做有助于解决问题。
这是我当前的.htaccess文件,我不确定如何将其设置为通过系统传递这些图像,而不是将它们视为文件而是将其视为URI:
# Turn on URL rewriting
RewriteEngine On
# Installation directory
RewriteBase /
# Protect hidden files from being viewed
<Files .*>
Order Deny,Allow
Deny From All
</Files>
RewriteCond %{HTTP_HOST} ^i.tinyuploadz.com
RewriteRule (.*) http://www.tinyuploadz.com/images%{REQUEST_URI} [NC,L,NS]
# Protect application and system files from being viewed
RewriteRule ^(?:application|modules|system)\b.* index.php/$0 [L]
# Allow any files or directories that exist to be displayed directly
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
# Image rediects?
#RewriteRule /images/(.+)\.jpg /images/$1.jpg [PT]
# Rewrite all other URLs to index.php/URL
RewriteRule .* index.php/$0 [PT]
# Fix the CSS an d JS
#RewriteRule ^(.*)\.[\d]{10}\.(css|js)$ $1.$2 [L]
# Do not let people browse our directories
Options -Indexes
以下是我当前设置PHP函数的方法(这是控制器生成的视图)
$day = date("d", $image['upload_time']);
$month = date("m", $image['upload_time']);
$year = date("Y", $image['upload_time']);
$url = IMAGE_URL . $year . '/' . $month . '/' . $day . '/' . $image['image_id'] . '.' . $image['extension'];
header('Content-type: ' . $image['mime']);
switch ($image['extension'])
{
case 'png':
$img = @imagecreatefrompng($url);
imagepng($img);
imagedestroy($img);
break;
case 'jpg':
case 'jpeg':
$img = @imagecreatefromjpeg($url);
imagejpeg($img);
imagedestroy($img);
break;
case 'gif':
if (is_ani($url))
{
readfile($url);
break;
}
$img = @imagecreatefromgif($url);
imagegif($img);
imagedestroy($img);
break;
case 'bmp':
// Seems like we can't do anything special for bmps
readfile($url);
break;
default:
readfile($url);
break;
}
//readfile($url . $image['image_id'] . '.' . $image['extension']);
// We don't want Kohana to break anything else with the header change
exit();
function is_ani($filename)
{
if(!($fh = @fopen($filename, 'rb')))
return false;
$count = 0;
//an animated gif contains multiple "frames", with each frame having a
//header made up of:
// * a static 4-byte sequence (\x00\x21\xF9\x04)
// * 4 variable bytes
// * a static 2-byte sequence (\x00\x2C) (some variants may use \x00\x21 ?)
// We read through the file til we reach the end of the file, or we've found
// at least 2 frame headers
while(!feof($fh) && $count < 2)
{
$chunk = fread($fh, 1024 * 100); //read 100kb at a time
$count += preg_match_all('#\x00\x21\xF9\x04.{4}\x00(\x2C|\x21)#s', $chunk, $matches);
}
fclose($fh);
return $count > 1;
}
感谢您对此事的任何帮助:)

尝试更改此内容:
#RewriteRule /images/(.+)\.jpg /images/$1.jpg [PT]
对此:
RewriteRule /images/(.+)\.jpg /images/$1.jpg [PT,L]
我怀疑Apache会解析重写规则,但之后只会在RewriteRule .* index.php/$0 [PT]
行上对其进行过滤,因此它最终会将所有内容传递给index.php。

HTTP请求无关紧要...因为当getimagesize拉取图像时,它与另一个浏览器相同。确保您将网址格式化为urlencode。
是否有机会获得实时网址以帮助更好地解决问题?
