MIME type类型

大家好，欢迎来到IT知识分享网。

MIME type 的缩写为(Multipurpose Internet Mail Extensions)代表互联网媒体类型(Internet media type)，MIME使用一个简单的字符串组成，最初是为了标识邮件Email附件的类

型，在html文件中可以使用content-type属性表示，描述了文件类型的互联网标准。

MIME类型能包含视频、图像、文本、音频、应用程序等数据。

MIME_type类型语法 

media-type=type “/” subtype *( “;” parameter ) 

媒体类型(type)与子类型(subtype)组成了MIME，它们之间使用反斜杠/分割，其中type可取值为：application audio example image message model multipart text video，

subtype是某种类型的唯一标识符，比如：css gif xml等。

MIME示例

text/css 标明此文件的type为text(文本)，且subtype为css(层叠样式表)

image/gif 标明此文件的type为image(图像)，且subtype为gif(Graphics Interchange Format)
