首先说一下来第一种,也是自认为自最简单的一句话搞定,也不用导jar包,需要import javax.activation.MimetypesFileTypeMap;
第二种,跟第一种差不多,不过里面的内容就少了很多,好多类型都没有,需要import java.net.FileNameMap;
import java.net.URLConnection;
第三种需要导入jmimemagic.jar,需要import net.sf.jmimemagic.Magic;
import net.sf.jmimemagic.MagicMatch;
第四种需要导入mime-util.jar,需要import eu.medsea.mimeutil.MimeUtil; import java.util.Collection;
Ⅱ torrent文件mime怎么设置
增加BT种子的Mime类型,使.torrent格式可以被下载,扩展名为.torrent,Mime类型为application/octet-stream,扩展名之类的都知道回,就是类型不答知道,现在记录下,免得再次忘记! 现在很多站长都在使用Windows主机做WEB服务器,在win主机中最主流的操作系统莫过于windows 2003了, 详细了解windows对于每个建站的人来说是一件无敌法宝,所以烈火建站学院的小编决定定期发一些技巧给大家,今天来说一下如何让IIS支持BT种子文件下载。 大家都知道,Win2003的IIS6默认是不支持torrent的,那么如何才能支持呢? 回答:需要手工添加。具体步骤如下: 在IIS里所需要的站点—属性—HTTP头—MIME类型–
Ⅲ 谁知道FLASH中老说的 MIME类型 是什么东西
复如果使用户能够观看WEB页上的动画制,必须正确配置WEB服务器,以便它能够识别FLASH电影文件,配置服务器就是为服务器建立适当的MIME类型,以便把文件同属于SHOCKWAVE FLASH的有.SWF后辍的文件联系起来。浏览器收到正确的MIME类型后,便载入合适的插件、控制器或者帮助程序来处理或者正确显示进入的数据。如果MIME类型丢失或者传递不正确,则浏览器会显示出一个错误通知或者一个空白的窗口。
我看了上面的可以这样理解:MIME定义flash在网页中显示的文件后缀为.swf~如果未定义MIME值,网页就显示不了!~

Ⅳ 文件拓展名 对应的MIME类型,文件下传上载有用怎么解决
解决mediawiki 文件扩展名 与检测到的文件MIME类型(application/zip)不匹配
标签: 扩展extension文档fileweb
在mediawiki中,如果上传doc或者docx文件时,经常会出现:文件扩展名".***" 与检测到的文件MIME类型(application/zip)不匹配 的警告。要想去掉这个警告,需要更改includes目录下的DefaultSettings.php文件,其中的 $wgVerifyMimeType = false, 即可。
本内容取自mediawiki官方文档。原文内容如下:
You can also disable the MIME type check completely by setting $wgVerifyMimeType = false; — note however that this is very insecure: arbitrary files can then be uploaded with a "harmless" file extension, but may possibly still executed/interpreted in a harmful way on the client computer, or the web server. Pending: how does this relate to$wgCheckFileExtensions?
Ⅵ MIME类型是什么意思啊
MIME类型就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。 MIME的英文全称是"Multipurpose Internet Mail Extensions" 多功能Internet 邮件扩充服务,它是一种多用途网际邮件扩充协议,在1992年最早应用于电子邮件系统,但后来也应用到浏览器。服务器会将它们发送的多媒体数据的类型告诉浏览器,而通知手段就是说明该多媒体数据的MIME类型,从而让浏览器知道接收到的信息哪些是MP3文件,哪些是Shockwave文件等等。服务器将MIME标志符放入传送的数据中来告诉浏览器使用哪种插件读取相关文件。 MIME能够支持非ASCII字符、二进制格式附件等多种格式的邮件消息。这个标准被定义在; RFC 2045,; RFC 2046,; RFC 2047,; RFC 2048,; RFC 2049等RFC中。 由RFC 822转变而来的RFC 2822,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,声音等非文字消息都不能在电子邮件中传输。MIME规定了用于表示各种各样的数据类型的符号化方法。 浏览器接收到文件后,会进入插件系统进行查找,查找出哪种插件可以识别读取接收到的文件。如果浏览器不清楚调用哪种插件系统,它可能会告诉用户缺少某插件,或者直接选择某现有插件来试图读取接收到的文件,后者可能会导致系统的崩溃。传输的信息中缺少MIME标识可能导致的情况很难估计,因为某些计算机系统可能不会出现什么故障,但某些计算机可能就会因此而崩溃。 检查一个服务器是否正确设置了MIME类型的步骤是: 1. 在Netscape浏览器中打开服务器网页 2. 进入"View"菜单,选择"Page Info" 3. 在弹出的窗口中点击上层框架中的"EMBED" 4. 在下层框架中查看MIME的类型是否为"application/x-director"或"application/x-shockwave-flash",如果是上述信息的话表明服务器已经正确设置了MIME类型;而如果MIME类型列出的是文本内容、八位一组的数据或是其它形式均表明服务器的MIME类型没有设置正确。 如果服务器没有正确标明其发送的数据的类型,服务器管理员应该正确添加相关信息,具体操作方法非常简单快捷。 Microsoft公司应用于Windows系统下的浏览器使用ActiveX控件,而不是Netscape插件,这种浏览器不必象其它浏览器那样依靠MIME的编码。"OBJECT"标签的"CLSID"属性准确地标明了应调用哪种程序来读取接收到的文件,因此浏览器不必象"EMBED"标签那样选择一种读取程序。正因为如此,你往往会在使用带插件的浏览器时遇到MIME问题,而使用ActiveX控件的浏览器则很少出现此类麻烦。 正由于上述工作方式的差别也解释了一种现象,不知你是否发现在使用Netscape浏览器播放WAV文件时,浏览器会调用LiveConnect插件进行播放,而其它浏览器一般都使用通用的QuickTime的播放插件等来进行播放,这是因为Netscape浏览器接收文件需要读取MIME标识符,以便决定调用哪种程序来读取接收的文件,而服务器设置在Netscape浏览器中播放WAV文件应使用LiveConnect插件,因此Netscape浏览器接收到WAV格式的文件时必然就会调用LiveConnect插件,但由于其它浏览器不使用这种方式,因此它们都使用系统默认的播放WAV格式文件的播放器。当然Flash电影文件并不存在这种问题,因为只有Flash播放器才能够正确读取这种格式的文件。 在把输出结果传送到浏览器上的时候,浏览器必须启动适当的应用程序来处理这个输出文档。这可以通过多种类型MIME(多功能网际邮件扩充协议)来完成。在HTTP中,MIME类型被定义在Content-Type header中。 例如,假设你要传送一个Microsoft Excel文件到客户端。那么这时的MIME类型就是“application/vnd.ms-excel”。在大多数实际情况中,这个文件然后将传送给Execl来处理(假设我们设定Execl为处理特殊MIME类型的应用程序)。在ASP中,设定MIME类型的方法是通过Response对象的ContentType属性。
Ⅶ java怎么获取文件的mime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。这是我在网络上摘抄的一段介绍,具体大家可以去网络查阅。
好,我们现在就来看看如何使用java获取文件的Content-Type的值,那么按照我的习惯,先来上代码:
30
import java.io.IOException;import java.nio.file.Files;import java.nio.file.Path;import java.nio.file.Paths;/** * 测试类 * @author ZY * */public class MIME_Demo { public static void main(String[] args) throws Exception { System.out.println(getContentType("F:/test.png")); System.out.println(getContentType("F:/2.doc")); System.out.println(getContentType("F:/2.csv")); System.out.println(getContentType("F:/LiveUpdate.exe")); System.out.println(getContentType("F:/1.txt")); System.out.println(getContentType("F:/demo.jpg")); } public static String getContentType(String filename){ String type = null; Path path = Paths.get(filename); try { type = Files.probeContentType(path); } catch (IOException e) { e.printStackTrace(); } return type; }}
这段代码的执行结果为:
image/png
application/msword
application/vnd.ms-excel
application/x-msdownload
text/plain
image/jpeg
Ⅷ 什么是mime类型
MIME的全称是Multipurpose Internet Mail Extensions,即多用途互联网邮件扩展类型。
这是HTTP协议中用来定义文档性质及格式的标回准。IETF RFC 6838,对HTTP传输内容答类型进行了全面定义。
而IANA(互联网号码分配机构)是负责管理所有标准MIME类型的官方机构。可以在这里)找到所有的标准MIME。
服务器通过MIME告知响应内容类型,而浏览器则通过MIME类型来确定如何处理文档。
MIME的格式:
type/subtype
这是一个两级的分类,第一级分类通常包含(见下图):
