Facebook打开图形og：图像转义空格字符 [英] Facebook open graph og:image escape whitespace characters

问题描述

我有一个用户提交的照片画廊的页面。我正在使用Facebook API分享照片。它与查询字符串共享页面。当查询字符串存在时，它将设置页面上的所有打开图形属性。除非图像在文件名上有空白字符，否则此功能非常好。

I have a page with user submitted photo galleries. I'm using the facebook API to share the photos. It shares the page with a query string. When the query string is present, it sets all the open graph properties on the page . This works great except when the image has white space characters on the file name.

我已经尝试用'％20'替换空格，因此

I have tried replacing the whitespace characters with '%20' as so

http://example.com/gallery/images/large/this image.jpg

到

 http://example.com/gallery/images/large/this%20image.jpg

但是，Facebook解析器也不喜欢。

But the facebook parser doesn't like that either.

有没有办法对这些字符进行扫描，或者我将不得不返回并更改它，以便在图像上传时更换？

Is there a way to scape these characters or am I going to have to go back and change it so that it replaces when the images get uploaded?

推荐答案

回答你的问题（原来是），现在（在2017年6月）Facebook解析器与空格字符一起逃逸'％20'，希望能帮助有人寻找解决方案。

Answering your question (being it old), Now (in June-2017) Facebook parser works with whitespace characters when escaped with '%20', hope it would help someone looking for solution.

所以，将空格转换为％20，如下所示：

So, convert whitespace to %20 as depicted below:

http://example.com/gallery/images/large/this image.jpg

to

http://example.com/gallery/images/large/this%20image.jpg

服务器端语言具有预定义的功能，例如PHP中的 rawurlencode 。

Server side language has pre-defined function for that e.g. rawurlencode in PHP.
