字体在Web客户端cors中被阻止 [英] fonts are blocked in web client cors

问题描述

当我在本地工作时，一切正常，但是现在我上传到托管服务器，并且字体被未知的（CORS）阻止。字体（和CSS，JS等）位于子域中，因为URL由索引解析（因此路径在域中不起作用）。 css / js可以正常工作。

While I was working in local everything worked perfectly, now I uploaded to a hosting and the fonts are being blocked by something I've never heard of (CORS). The fonts (and css, js, etc) are in a subdomain because urls are parsed by the index (so paths are not working in the domain). The css/js are working ok.

这是Web控制台（Firefox）中的输出：

This is the output in the web console (firefox):

Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at /fonts/Oxygen-Regular.ttf. (Reason: CORS header 'Access-Control-Allow-Origin' missing). <unknown>

我搜索了此问题，但找不到字体的具体问题和确切的错误消息。

I searched for this problem but i cannot find this especific problem with fonts and the exact error message.

编辑：

解决方法是为提供文件的域/文件夹。该配置可以在虚拟主机块中，也可以在.htaccess文件中（在文件所在的文件夹中）。我更喜欢在vhost块中进行设置：

The fix is to enable the header for the domain / folder serving the files. The config can be either in the virtual host block or in a .htaccess file (in the folder where the files are). I prefer setting it in the vhost block:

<IfModule mod_headers.c>
    SetEnvIf Origin "https://(www|sub1|sub2|sub3).domain.com)$" ACAO=$0
    Header set Access-Control-Allow-Origin "%{ACAO}e" env=ACAO
    Header set Access-Control-Allow-Methods "GET"
</IfModule>

在此示例中， Access-Control-Allow-Origin 仅发送白名单域和子域的标头。我从 domain.com 重定向到 www.domain.com ，所以此示例不接受没有<$的域c $ c> www 。

In this example, the Access-Control-Allow-Origin will only send the header for the whitelisted domain and subdomains. I redirect from domain.com to www.domain.com so this example won't accept a domain without www.

推荐答案

您的浏览器抱怨缺少标题：访问控制-Allow-Origin

Your browser is complaining about a missing header: Access-Control-Allow-Origin

由于缺少此标头，因此您的浏览器不知道所需的访问权限是合法的。查看 http://enable-cors.org 并选择适合您服务器的配置。

Because this header is missing your browser does not know that the desired access is legit. Have a look at http://enable-cors.org and choose the configuration appropriate for your server.

您需要配置存储字体的服务器！

You need to configure the server where the fonts are stored !
