文件格式和对应的ContentType 对应表

文件名和其文档类型的对应规则，每个文件都有不一样的文件后缀.txt ,  .html , .zip 他们的文档类型是不一样的。详细请看 文件名和对应的ContentType 对应表 。
并且提供了一个java读取这些属性的代码供参考。

定义

HTML中的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，决定浏览器将以什么形式、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。

ASP中的ContentType

ContentType属性指定响应的 HTTP内容类型。如果未指定 ContentType，默认为TEXT/HTML。

2语法规则编辑

GZIP中的　Content-Type=text/ht*/js/css/php

3语法编辑

HTML

<meta content="text/html; charset=gb2312" http-equiv="Content-Type"/>

Response.ContentType [= ContentType]

Java Servlet

response.setContentType(String);

4参数编辑

HTML

content

即为类型，具体参照下文的“ContentType的类型”

charset

决定网页的编码，一般为gb2312、UTF-8等

ContentType

描述内容类型的字符串。该字符串通常被格式化为类型/子类型，其中类型是常规内容范畴而子类为特定内容类型。有关支持内容类型的完整列表，请参阅 Web 浏览器文档或当前的 HTTP 规格说明。

示例

下面的示例将内容类型设置为 Channel Definition Format（CDF）。

<% Response.ContentType = "application/x-cdf" %>

下面的示例将 ContentType 属性设置为其他的常见值。

<% Response.ContentType = "text/HTML" %>

<% Response.ContentType = "image/GIF" %>

<% Response.ContentType = "image/JPEG" %>

应用于

Response 对象

关于详细的类型对应参看ContentType的类型。

  存到contentType.proerties 文件中，再使用classLoad读出来

java代码访问
