通Base64编码的jpeg图像OG：图像 [英] Pass Base64 jpeg image to og:image

问题描述

我有一个在运行时所产生在我的网站的形象和我在HTML中使用显示它

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

<img src="data:image/jpeg;base64,<!-- base64 data -->" />

现在，我要为Facebook获取这一形象，但如果我做OG相同的：像meta标签，Facebook的调试器给我一个错误。任何解决方案？

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，我想避免的文件永久保存，因为它们总是不同的，那就太拥挤非常快

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

PASE到一个PHP文件，呼应一下：

pase it to a php file that echo it out:

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

德coder.php：

decoder.php:

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