IANA官方MIME类型大全 IBM Integration Bus v10.1 MDN Web Docs MIME（Multipurpose Internet Mail Extensions，邮件扩展类型）是一种标准的、用来表示文档、文件、字节流等数据的格式和性质的一种流媒体类型。
浏览器通常采用MIME类型而不是文件扩展名来确定如何处理URL和文件内容。所以在响应头需要添加标准的mimetype，否则浏览器将不能以正常的方式来处理解析文件内容。
通用结构：
type/subtype
MIME的组成结构；由类型与子类型两个字符串中间用/分隔而组成。不允许空格存在。type表示可以被分多个子类的独立类别。subtype表示细分后的每个类型。
MIME类型对大小写不敏感，但是传统写法都是小写。
在打开网站的调试模式的时候，我们可以看到，在请求的响应标头往往有一个Content-Type的属性，Content-Type的第一个属性往往都是mimetype的类型，通过;来分割。
从MIME的全称和其历史，MIME最开始的提出是为了解决邮件编码而扩展的一种类型。邮件协议在最开始提出的时候，只能传输一定长度的ASCII码文件，随着计算机网络的发展，单纯的ASCII码显然不能满足世界的多样化需求。所以此时MIME就诞生了，MIME作为电子邮件协议SMTP的Extensions扩展，它并没有取代或改变SMTP协议，而仅仅是对SMTP协议的一种扩展。通过MIME协议，使得邮件传输过程中不会被邮件协议而改变。
万维网和HTTP协议的诞生要晚于邮件协议的诞生，在HTTP协议的发展中，广泛吸收了其他协议的优点，如MIME。在HTTP协议中，通过Content-Type标头来确定HTTP传输的内容，从其功能来看，可以确定是借鉴了MIME。且在Content-Type标头中，通常其第一个值为MIME规范中所支持的mimetype，其他属性通过过;来分割。所以可以说Content-Type是mimetype的超集，在Content-Type中包含了对mimetype的定义和使用。

MIME类型 描述 multipart/form-data 可用于联系 HTML Forms 和 POST 方法 multipart/byteranges 使用状态码206 Partial Content来发送整个文件的子集 multipart/related 用于消息中多个相关部分。 具体地讲，与 SwA（具有附件的 SOAP）一起使用 multipart/signed 用于消息中多个相关部分（包括签名）。 具体的讲，与 S/MIME 一起使用 multipart/mixed 用于消息中多个独立部分。
