MIME Type 與 Content-Type 的關系
首先看看tomcat伺服器中預設的web.xml中的描述:
<!-- ===================== Default MIME Type Mappings =================== -->
<!-- When serving static resources, Tomcat will automatically generate -->
<!-- a "Content-Type" header based on the resource's filename extension, -->
<!-- based on these mappings. Additional mappings can be added here (to -->
<!-- apply to all web applications), or in your own application's web.xml -->
<!-- deployment descriptor. -->
再看看apache伺服器中mime.types的描述:
# This file controls what Internet media types are sent to the client for
# given file extension(s). Sending the correct media type to the client
# is important so they know how to handle the content of the file.
# Extra types can either be added here or by using an AddType directive
# in your config files. For more information about Internet media types,
# please read RFC 2045, 2046, 2047, 2048, and 2077. The Internet media type
# registry is at <http://www.iana.org/assignments/media-types/>.
當web伺服器收到靜态的資源檔案請求時,依據請求檔案的字尾名在伺服器的MIME配置檔案中找到對應的MIME Type,
再根據MIME Type設定HTTP Response的Content-Type,然後浏覽器根據Content-Type的值處理檔案。
浏覽器對Content-Type的處理方式都可以設定:
IE:同檔案浏覽器,【控制台】->【檔案夾選項】->【檔案類型】中修改。
Firefox:【工具】->【選項】->【應用程式】中修改。
Opera:【工具】->【首選項】->【進階】->【下載下傳】中修改。

MIME 參考手冊:http://www.w3school.com.cn/media/media_mimeref.asp
MIME定義:http://zh.wikipedia.org/w/index.php?title=MIME&variant=zh-hans
MIME MIME類型就是設定某種擴充名的檔案用一種應用程式來打開的方式類型,當該擴充名檔案被通路的時候,浏覽器會自動使用指定應用程式來打開。多用于指定一些用戶端自定義的檔案名,以及一些媒體檔案打開方式。
MIME的英文全稱是"Multipurpose Internet MailExtensions" 多功能Internet郵件擴充服務,它是一種多用途網際郵件擴充協定,在1992年最早應用于電子郵件系統,但後來也應用到浏覽器。伺服器會将它們發送的多媒體資料的類型告訴浏覽器,而通知手段就是說明該多媒體資料的MIME類型,進而讓浏覽器知道接收到的資訊哪些是MP3檔案,哪些是Shockwave檔案等等。伺服器将MIME标志符放入傳送的資料中來告訴浏覽器使用哪種插件讀取相關檔案。
MIME能夠支援非ASCII字元、二進制格式附件等多種格式的郵件消息。這個标準被定義在;RFC 2045,; RFC 2046,; RFC 2047,; RFC 2048,; RFC 2049等RFC中。 由RFC822轉變而來的RFC2822,規定電子郵件标準并不允許在郵件消息中使用7位ASCII字元集以外的字元。正因如此,一些非英語字元消息和二進制檔案,圖像,聲音等非文字消息都不能在電子郵件中傳輸。MIME規定了用于表示各種各樣的資料類型的符号化方法。
浏覽器接收到檔案後,會進入插件系統進行查找,查找出哪種插件可以識别讀取接收到的檔案。如果浏覽器不清楚調用哪種插件系統,它可能會告訴使用者缺少某插件,或者直接選擇某現有插件來試圖讀取接收到的檔案,後者可能會導緻系統的崩潰。傳輸的資訊中缺少MIME辨別可能導緻的情況很難估計,因為某些計算機系統可能不會出現什麼故障,但某些計算機可能就會是以而崩潰。
檢查一個伺服器是否正确設定了MIME類型的步驟是:
1. 在Netscape浏覽器中打開伺服器網頁
2. 進入"View"菜單,選擇"Page Info"
3. 在彈出的視窗中點選上層架構中的"EMBED"
4.在下層架構中檢視MIME的類型是否為"application/x-director"或"application/x-shockwave-flash",如果是上述資訊的話表明伺服器已經正确設定了MIME類型;而如果MIME類型列出的是文本内容、八位一組的資料或是其它形式均表明伺服器的MIME類型沒有設定正确。
如果伺服器沒有正确标明其發送的資料的類型,伺服器管理者應該正确添加相關資訊,具體操作方法非常簡單快捷。
Microsoft公司應用于Windows系統下的浏覽器使用ActiveX控件,而不是Netscape插件,這種浏覽器不必象其它浏覽器那樣依靠MIME的編碼。"OBJECT"标簽的"CLSID"屬性準确地标明了應調用哪種程式來讀取接收到的檔案,是以浏覽器不必象"EMBED"标簽那樣選擇一種讀取程式。正因為如此,你往往會在使用帶插件的浏覽器時遇到MIME問題,而使用ActiveX控件的浏覽器則很少出現此類麻煩。
正由于上述工作方式的差别也解釋了一種現象,不知你是否發現在使用Netscape浏覽器播放WAV檔案時,浏覽器會調用LiveConnect插件進行播放,而其它浏覽器一般都使用通用的QuickTime的播放插件等來進行播放,這是因為Netscape浏覽器接收檔案需要讀取MIME辨別符,以便決定調用哪種程式來讀取接收的檔案,而伺服器設定在Netscape浏覽器中播放WAV檔案應使用LiveConnect插件,是以Netscape浏覽器接收到WAV格式的檔案時必然就會調用LiveConnect插件,但由于其它浏覽器不使用這種方式,是以它們都使用系統預設的播放WAV格式檔案的播放器。當然Flash電影檔案并不存在這種問題,因為隻有Flash播放器才能夠正确讀取這種格式的檔案。
在把輸出結果傳送到浏覽器上的時候,浏覽器必須啟動适當的應用程式來處理這個輸出文檔。這可以通過多種類型MIME(多功能網際郵件擴充協定)來完成。在HTTP中,MIME類型被定義在Content-Type header中。
例如,假設你要傳送一個MicrosoftExcel檔案到用戶端。那麼這時的MIME類型就是“application/vnd.ms-excel”。在大多數實際情況中,這個檔案然後将傳送給Execl來處理(假設我們設定Execl為處理特殊MIME類型的應用程式)。在ASP中,設定MIME類型的方法是通過Response對象的ContentType屬性。
多媒體檔案格式MIME
最早的HTTP協定中,并沒有附加的資料類型資訊,所有傳送的資料都被客戶程式解釋為超文本标記語言HTML 文檔,而為了支援多媒體資料類型,HTTP協定中就使用了附加在文檔之前的MIME資料類型資訊來辨別資料類型。
MIME意為多目Internet郵件擴充,它設計的最初目的是為了在發送電子郵件時附加多媒體資料,讓郵件客戶程式能根據其類型進行處理。然而當它被HTTP協定支援之後,它的意義就更為顯著了。它使得HTTP傳輸的不僅是普通的文本,而變得豐富多彩。
每個MIME類型由兩部分組成,前面是資料的大類别,例如聲音audio、圖象p_w_picpath等,後面定義具體的種類。
常見的MIME類型
超文本标記語言文本 .html,.html text/html
普通文本 .txt text/plain
RTF文本 .rtf application/rtf
GIF圖形 .gif p_w_picpath/gif
JPEG圖形 .jpeg,.jpg p_w_picpath/jpeg
au聲音檔案 .au audio/basic
MIDI音樂檔案 mid,.midi audio/midi,audio/x-midi
RealAudio音樂檔案 .ra, .ram audio/x-pn-realaudio
MPEG檔案 .mpg,.mpeg video/mpeg
AVI檔案 .avi video/x-msvideo
GZIP檔案 .gz application/x-gzip
TAR檔案 .tar application/x-tar
Internet中有一個專門組織IANA來确認标準的MIME類型,但Internet發展的太快,很多應用程式等不及IANA來确認他們使用的MIME類型為标準類型。是以他們使用在類别中以x-開頭的方法辨別這個類别還沒有成為标準,例如:x-gzip,x-tar等。事實上這些類型運用的很廣泛,已經成為了事實标準。隻要客戶機和伺服器共同承認這個MIME類型,即使它是不标準的類型也沒有關系,客戶程式就能根據MIME類型,采用具體的處理手段來處理資料。而Web伺服器和浏覽器(包括作業系統)中,預設都設定了标準的和常見的MIME類型,隻有對于不常見的 MIME類型,才需要同時設定伺服器和客戶浏覽器,以進行識别。
由于MIME類型與文檔的字尾相關,是以伺服器使用文檔的字尾來區分不同檔案的MIME類型,伺服器中必須定義文檔字尾和MIME類型之間的對應關系。而客戶程式從伺服器上接收資料的時候,它隻是從伺服器接受資料流,并不了解文檔的名字,是以伺服器必須使用附加資訊來告訴客戶程式資料的MIME類型。伺服器在發送真正的資料之前,就要先發送标志資料的MIME類型的資訊,這個資訊使用Content-type關鍵字進行定義,例如對于HTML文檔,伺服器将首先發送以下兩行MIME辨別資訊,這個辨別并不是真正的資料檔案的一部分。
Content-type: text/html
注意,第二行為一個空行,這是必須的,使用這個空行的目的是将MIME資訊與真正的資料内容分隔開。
MIME利用了一個事實就是,RFC822在消息體的内容中做了一點限制:唯一的限制就是隻能使用簡單的ASCII文本。是以,MIME資訊由正常的Internet文本郵件組成,文本郵件擁有一些特别的符合RFC 822的資訊頭和格式化過的資訊體(用ASCII的子集來表示的附件)。這些MIME頭給出了一種在郵件中表示附件的特别的方法。
MIME資訊的剖析
一個普通的文本郵件的資訊包含一個頭部分(To: From: Subject:等等)和一個體部分(HelloMr.,等等)。在一個符合MIME的資訊中,也包含一個資訊頭并不奇怪,郵件的各個部分叫做MIME段,每段前也綴以一個特别的頭。MIME郵件隻是基于RFC 822郵件的一個擴充。然而它有着自己的RFC規範集。
頭字段
MIME頭根據在郵件包中的位置,大體上分為MIME資訊頭和MIME段頭。(譯者:MIME資訊頭指整個郵件的頭,而MIME段頭隻每個MIME段的頭。)
MIME資訊頭有:
MIME-Version:
這個頭提供了所用MIME的版本号。這個值習慣上為1.0。
Content-Type:
它定義了資料的類型,以便資料能被适當的處理。有效的類型有:text,
p_w_picpath,audio,video,applications,multipart和message。注意任何一個二進制附件都應該被叫做application/octet-stream。這個頭的一些用例為:p_w_picpath/jpg,application/mswork,multipart/mixed,這隻是很少的一部分。
Content-Transfer-Encoding:
這是所有頭中最重要的一個,因為它說明了對資料所執行的編碼方式,客
戶/MUA 将用它對附件進行解碼。對于每個附件,可以使用7bit,8bit,
binary,quoted-printable,base64和custom中的一種編碼方式。7bit編碼是用在USASCII字元集上的常用的一種編碼方式,也就是,保持它的原樣。8bit和binary編碼一般不用。對人類可讀的标準文本,如果傳輸要經過對格式有影響的網關時對其進行保護,可以使用quoted printable。Base64是一種通用方法,在需要決定使用哪一種編碼方法時,它提供了一個不用費腦子的選擇;它通常用在二進制,非文本資料上。注意,任何非7bit資料必須用一種模式編碼,這樣它就可以通過Internet郵件網關!
Content-ID:
如果Content-Type是message/external-body或multipart/alternative時,這個
頭就有用了。它超出了本文的範圍。
Content-Description:
這是一個可選的頭。它是任何資訊段内容的自由文本描述。描述必須使用us-ascii碼。
Content-Disposition:
一個試驗性的頭,它用于給客戶程式/MUA提供提示,來決定是否在行内顯示附件或作為單獨的附件。
MIME段頭(出現在實際的MIME附件部分的頭),除了MIME-Version頭,可以擁有以上任何頭字段。如果一個MIME頭是資訊塊的一部分,它将作用于整個資訊體。例如,如果Content-Transfer-Encoding顯示在資訊(指整個資訊)頭中,它應用于整個資訊體,但是如果它顯示在一個MIME段裡,它"隻能"用于那個段中.
