将 Base64 jpeg 图像传递给 og:image

问题描述

我的网站上有运行时生成的图像，我使用

I have image that is being generated in runtime on my website and I display it in html using

现在，我想让 Facebook 获取此图像，但是如果我对 og:image 元标记执行相同操作，则 Facebook 调试器会给我一个错误.有什么解决办法吗?

Now, I want for Facebook to fetch this image, but if I do the same for og:image meta tag, facebook debugger gives me an error. Any solution?

<meta property='og:image' content='data:image/jpeg;base64,<!-- base64 data -->'/>

当然，我想避免永久保存文件，因为它们总是不同的，而且很快就会变得太拥挤

Of course, I would like to avoid permanent saving of files since they are always different and it would get too crowded very quickly

推荐答案

将其粘贴到一个 php 文件中，然后将其回显:

pase it to a php file that echo it out:

<meta property='og:image' content='decoder.php?data=<!-- base64 data -->'/>

解码器.php:

<?php
    echo base64_decode($_GET['data']);
?>
