nginx - Nginx MIME类型和gzip

Question

Nginx允许您将文件扩展名映射到mime类型。作为the documentation says，它甚至带有一个预先构建的mime类型列表（在问题末尾粘贴）。

我一直信任此列表，并且一切正常，但是现在我注意到某些类型丢失了。

application/javascript和application/json呢？

它使用旧的不推荐使用的application/x-javascript，我想这是为了确保IE支持...但是真的可以吗？



另外，应该压缩哪些类型的文件？

我一直在以下代码段中使用该列表，尽管我承认它只是示例nginx conf文件的一部分，几年前，当我刚开始使用nginx时，它只是一个示例。

我还应该包含application/json吗？

http {
    include mime.types;
    default_type application/octet-stream;

    gzip_types text/plain text/xml text/css
               text/comma-separated-values
               text/javascript application/x-javascript
               application/atom+xml;

    # text/html is included in the gzip list by default                   

    # ...
}

/etc/nginx/mime.types中的默认mime类型。

types {
    text/html                             html htm shtml;
    text/css                              css;

好吧，没有：

Changes with nginx 1.5.4                                         27 Aug 2013

*) Change: the "js" extension MIME type has been changed to
   "application/javascript"; default value of the "charset_types"
   directive was changed accordingly.

为什么不？ nginx中的默认 mime.types文件仅包含用于或多或少常见文件扩展名的MIME类型。而且，拥有 json静态文件当然不是很普遍。


另外，应该压缩哪些类型的文件？


您可以为网站上所有可压缩的内容添加MIME类型。但是对于静态文件，最好使用 gzip static module。
