mime.types 文件用于定义不同文件扩展名与MIME类型之间的映射关系。MIME类型用于告诉浏览器如何处理不同类型的文件，例如显示文本文件、播放音频或视频文件等。下面是文件内容的解释：
解释
- types { ... }:
- 这一部分包含了MIME类型到文件扩展名的映射。每一行定义了一个MIME类型及其对应的文件扩展名。
- 示例条目解释：
- text/html html htm shtml;:
- 定义了扩展名为 html、htm 和 shtml 的文件对应的MIME类型是 text/html。
- image/jpeg jpeg jpg;:
- 定义了扩展名为 jpeg 和 jpg 的文件对应的MIME类型是 image/jpeg。
- application/javascript js;:
- 定义了扩展名为 js 的文件对应的MIME类型是 application/javascript。
- application/json json;:
- 定义了扩展名为 json 的文件对应的MIME类型是 application/json。
- 不同类型的文件：
- 文本文件:
- text/html：.html .htm .shtml
- text/css：.css
- text/xml：.xml
- text/plain：.txt
- 图像文件:
- image/gif：.gif
- image/jpeg：.jpeg .jpg
- image/png：.png
- image/svg+xml：.svg .svgz
- image/webp：.webp
- 音频文件:
- audio/mpeg：.mp3
- audio/ogg：.ogg
- 视频文件:
- video/mp4：.mp4
- video/webm：.webm
- 应用程序文件:
- application/json：.json
- application/pdf：.pdf
- application/zip：.zip
总结
mime.types 文件用于告诉Nginx如何根据文件扩展名设置HTTP头中的MIME类型。这有助于浏览器正确处理和显示不同类型的文件内容。例如，浏览器在收到 Content-Type: text/html 时会将文件作为HTML文档处理，而在收到 Content-Type: image/jpeg 时会将文件作为JPEG图像处理。
