想着微软跟中国政府关系还行，不像 google 的 cdn 容易被墙，就用了它的 cdn
主要是 bootstrap 的库，没想到

Font from origin 'http://ajax.aspnetcdn.com' has been blocked from loading by Cross-Origin Resource Sharing policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://127.0.0.1:8000' is therefore not allowed access.

这不是 CDN 端的问题，而是本地 Web 服务器没有开启 CORS

@TrustyWolf 不是 CDN 的服务器开启 CORS 么？

@TrustyWolf 看着好像是 CDN 拒绝了本地 127.0.0.1 啊。而且一般本地都不会特意去设置 CORS 的吧。

貌似最近的 http://ajax.aspnetcdn.com 都会重新向到 https://ajax.aspnetcdn.com

这个跨域不是 cdn 的问题，图方便就用--disable-web-security 参数启动 chrome ，本地环境调试线上接口方便的不要不要的

看到 block 就以为是政府干的了？
这个和墙以及微软没多大关系吧

@wm5d8b 我的是字母数字符号。。。。从 1080p 里裁剪了一个 400*400 还是 900*900 的。。。忘记了

提供字体文件的 web 服务需要添加
Access-Control-Allow-Origin: *
http 头来允许可以访问的域，这样字体文件才能跨越使用。

不过 Azure 的存储服务是有这个设置的，是不是微软忘记改了。

配置个 hostname 应该就可以了吧？

sudo vim /etc/hosts

添加一行

yoursite.me 127.0.0.1

然后用 yoursite.me 访问

@Showfom 你的 https 里有 2 行 Access-Control-Allow-Origin: *还没解决呢……

curl -I http://cdn.css.net/fonts/css?family=Open+Sans

@Showfom 更具体的 log ，带 IP ，还有同节点其他 IP 也是这样
