MIME (多用途互联网邮件扩展类型)
MIME(Multipurpose Internet Mail Extensions)多用途互联网邮件扩展类型。是设定某种扩展名的文件用一种应用程序来打开的方式类型,当该扩展名文件被访问的时候,浏览器会自动使用指定应用程序来打开。多用于指定一些客户端自定义的文件名,以及一些媒体文件打开方式。
它是一个互联网标准,扩展了电子邮件标准,使其能够支持:
非ASCII字符文本;非文本格式附件(二进制、声音、图像等);由多部分(multiple parts)组成的消息体;包含非ASCII字符的头信息(Header information)。
这个标准被定义在RFC 2045、RFC 2046、RFC 2047、RFC 2048、RFC 2049等RFC中。 MIME改善了由RFC 822转变而来的RFC 2822,这些旧标准规定电子邮件标准并不允许在邮件消息中使用7位ASCII字符集以外的字符。正因如此,一些非英语字符消息和二进制文件,图像,声音等非文字消息原本都不能在电子邮件中传输(MIME可以)。MIME规定了用于表示各种各样的数据类型的符号化方法。 此外,在万维网中使用的HTTP协议中也使用了MIME的框架,标准被扩展为互联网媒体类型。
在HTTP中,MIME类型被定义在Content-Type header中。每个MIME类型由3部分组成:Content-Type: [type]/[subtype]。前者是数据大类别,后者定义具体的种类。
ContentType
Content-Type,内容类型,一般是指网页中存在的Content-Type,用于定义网络文件的类型和网页的编码,决定文件接收方将以什么形式、什么编码读取这个文件,这就是经常看到一些Asp网页点击的结果却是下载到的一个文件或一张图片的原因。
ContentType属性指定响应的 HTTP内容类型。如果未指定 ContentType,默认为TEXT/HTML。
