包路径：org.openide.filesystems.FileUtil
类名称：FileUtil
方法名：getMIMEType

FileUtil.getMIMEType介绍

[英]Obtain MIME type for a well-known extension. If there is a case-sensitive match, that is used, else will fall back to a case-insensitive match.
[中]获取已知扩展的MIME类型。如果使用了区分大小写的匹配，else将返回到不区分大小写的匹配。

* <P>
* The default implementation calls {@link FileUtil#getMIMEType}.
* (As a fallback return value, <code>content/unknown</code> is used.)
* @return the MIME type textual representation, e.g. <code>"text/plain"</code>; never <code>null</code>
