在Kohana 3.2视图中输出图像 [英] output image in a Kohana 3.2 view

问题描述

我有以下脚本将图像输出到浏览器，工作正常。

I have the following script to output an image to the browser wich works fine.

$file_to_output=$_SERVER['DOCUMENT_ROOT'].'/static/imgs/uploads/20110318172207_16.jpg';
header('Content-Type: image/jpeg');
$raw=imagecreatefromjpeg($file_to_output);

// Output the image
imagejpeg($raw);

// Free up memory
imagedestroy($raw);

当我在视图中放入完全相同的代码时，它不再起作用并给出一堆像这样的stange字符：$ b $b JFIF > CREATOR：gd-jpeg v1.0（使用IJG JPEG v62），默认质量 C

when I put this exact same code in a view its doesn't work anymore and give a bunch of stange characters like this: ����JFIF��>CREATOR: gd-jpeg v1.0 (using IJG JPEG v62), default quality ��C

我需要做些什么才能让它在视图中工作？

What do I have to do to make it work in a view?

推荐答案

你不应该把它放进去一个看法。所有视图输出都被缓冲，稍后通过Response对象返回。

You're not supposed to put that into a view. All view output is buffered, being returned through a Response object later.

这是所有响应逻辑，因此您的操作代码应如下所示：

This is all response logics, so your action code should look like:

$path = DOCROOT.'static/imgs/uploads/20110318172207_16.jpg';

$this->response->headers('content-type',File::mime($path))
    ->body(file_get_contents($path));
