最近不知道怎么了，我的下载站就一直没法加载静态文件，然后我去看了一下浏览器开发工具的输出，全部都是无法加载(请求超时)，因为这些文件都在官方的CDN上所以我也没法判断具体出现了什么问题，我研究了一下，使用学校的网络访问这个CDN根本就上不去，一直是TimeOut而且没有任何来自对方服务器的响应，但是使用我的香港服务器curl一下却发现能通，真的是日了dog了，然后我尝试把所有加载失败的文件全部使用wget下载到我专门存放静态文件的站点上，全部下载成功了：

但是我一加载网站发现字体全部无法加载：
全部字体报错：
已拦截跨源请求：同源策略禁止读取位于 https://static.linxi.info/webfonts/fa-solid-900.woff2 的远程资源。（原因：CORS 头 'Access-Control-Allow-Origin' 不匹配 'origin-list'）。
然后我去看了一下mozilla官方的开发文档发现了以下解决方法：
add_header 'Access-Control-Allow-Origin' '你的网站域名';
我添加到了nginx的站点配置文件中，但是似乎并没有其任何作用，仍然报错，我又看了一遍文档，又发现了以下内容：
我又把配置文件中的"add_header 'Access-Control-Allow-Origin' 'https://api.service.linxi.info';"修改为"add_header 'Access-Control-Allow-Origin' '*';"
add_header 'Access-Control-Allow-Origin' '*';
刷新网站，问题成功解决！
