问题描述
我正在尝试使用 Yii::app()->request->sendFile() 在视图中显示图像而不弹出下载对话框"，但我是无法这样做，因为 sendFile 正在将 Content-Desposition 设置为 attachment.如何将其设置为 inline ?
I am trying to use Yii::app()->request->sendFile() to display images in the view without the 'Download Dialog box' popping up, but I am unable to do so as sendFile is setting Content-Desposition to attachment. How do I make it set it to inline ?
顺便说一句，我使用过 xsendfile 函数，但由于您需要在 Apache 中使用 mod-xsendfile 来使用它，因此放弃了它.
BTW I have used xsendfile function, but ditched it as you need mod-xsendfile in Apache to use it.
请帮忙.
推荐答案
如果要在视图中显示图像，则需要使用 标签.
If you want to display images in the view then you need to use <img> tags.
如果您希望返回的内容成为一个图像(在这种情况下谈论视图是没有意义的)那么您需要做的通常不超过
If you want the returned content to be an image (in which case it's meaningless to talk about a view) then all you need to do is usually no more than
header('Content-Type: image/jpeg');
echo $binaryImageContents;
Yii::app()->end();
这也是 sendFile() 原则上所做的，尽管它提供了更多的便利，因为它从文件的扩展名中检测适当的 MIME 类型并发送一堆额外的 HTTP 响应头(包括不受欢迎的 Content-Disposition 一).你可以看看为自己.
That's also what sendFile() does in principle, although it offers a bit more convenience because it detects the appropriate MIME type from the file's extension and sends a bunch of additional HTTP response headers (including the undesirable Content-Disposition one). You can take a look for yourself.
