nginx配置都媒体文件Content-Type

发布时间 2023-04-04 11:39:17作者: 熊先生不开玩笑

用nginx做代理用来做多媒体文件的下载，因为有些文件名后缀类型没有匹配。所以返回个请求端的响应头会是：
Content-Type: application/octet-stream，给请求端造成困扰。例如：acc 文件需要是： Content-Type: audio/aac，wav 文件需要是：Content-Type: audio/x-wav。一种临时的解决办法是nginx配置文件里加上类型对应：

vim /etc/nginx/mime.types;

加入如下配置，也可以按需增加：

types {
     # Audio
     audio/midi mid midi kar;
     audio/mp4 aac f4a f4b m4a;
     audio/mpeg mp3;
     audio/ogg oga ogg opus;
     audio/x-realaudio ra;
     audio/x-wav wav;

}

重载nginx配置，用curl -I , 命令查看响应头。

另外：以上只是一种很普通的做法。实际如果我们是自己做文件存储服务，需要需要读取文件的文件头获得文件类型。而不是根据文件命名后缀。
