HTTP标头后mod_rewrite的JPG文件 [英] HTTP headers for jpg files after mod_rewrite

问题描述

我使用Apache的的mod_rewrite 来我的网站根目录外的路由请求JPG文件到一个目录。

I'm using Apache's mod_rewrite to route requests for JPG files to a directory outside my web root.

它通常一直很好，但也有不显示一些图片。后来我意识到，当我使用PHP的 get_headers（）功能对我的形象的网址，他们都返回结果
的Content-Type：text / html的;字符集= UTF-8 而不是正确的图像/ JPEG 头类型。

It generally has been fine, but there are a few images that do not display. I then realized that when I use PHP's get_headers() function on my image URLs, they are all returning
Content-Type: text/html; charset=UTF-8 instead of the proper image/jpeg header types.

我已经尝试明确地设置内容类型：图像/ JPEG 头静静的，没有我的图片返回正确的标题 - 虽然大多数人正常显示，但我M不知道为什么。

I have tried explicitly setting the Content-Type: image/jpeg header and still, none of my images return the correct headers - although most do display correctly, but I'm not sure why.

我怎样才能保证一个JPG文件通过的mod_rewrite ？

How can I assure a JPG file is sent with the correct header when redirecting via mod_rewrite?

推荐答案

这是你能做些什么。创建一个PHP文件，将得到正确的文件，并通过

This is what you could do. Create a PHP file that will get the right file and passes it through

<?php 
$sImage = 'imagename.jpg';
header("Content-Type: image/jpeg");
header("Content-Length: " .(string)(filesize($sImage)) );

echo file_get_contents($sImage);

或

<?php
$sImage = 'imagename.jpg';
$rFP = fopen($sImage, 'rb');

header("Content-Type: image/jpeg");
header("Content-Length: " .(string)(filesize($sImage)) );

fpassthru($rFP);
exit;
