一蝉仇、MIME TYPE 描述

多用途互聯(lián)網(wǎng)郵件擴展（MIME，Multipurpose Internet Mail Extensions）是一個互聯(lián)網(wǎng)標準，它擴展了電子郵件標準矫户，使其能夠支持非ASCII字符、二進制格式附件等多種格式的郵件消息残邀。

二皆辽、內(nèi)容類型（Content-Type）

這個頭部領域用于指定消息的類型柑蛇。一般以下面的形式出現(xiàn)。[type]/[subtype]
type 有下面的形式：

Text：用于標準化地表示的文本信息驱闷，文本消息可以是多種字符集和或者多種格式的耻台；
Multipart：用于連接消息體的多個部分構(gòu)成一個消息，這些部分可以是不同類型的數(shù)據(jù)空另；
Application：用于傳輸應用程序數(shù)據(jù)或者二進制數(shù)據(jù)盆耽；
Message：用于包裝一個E-mail消息；
Image：用于傳輸靜態(tài)圖片數(shù)據(jù)痹换；
Audio：用于傳輸音頻或者音聲數(shù)據(jù)征字；
Video：用于傳輸動態(tài)影像數(shù)據(jù)，可以是與音頻編輯在一起的視頻數(shù)據(jù)格式娇豫。
subtype用于指定type的詳細形式。content-type/subtype配對的集合和與此相關的參數(shù)畅厢，將隨著時間而增長冯痢。為了確保這些值在一個有序而且公開的狀態(tài)下開發(fā)，MIME使用Internet Assigned Numbers Authority (IANA)作為中心的注冊機制來管理這些值框杜。常用的subtype值如下所示：
text/plain（純文本）
text/html（HTML文檔）
application/xhtml+xml（XHTML文檔）
image/gif（GIF圖像）
image/jpeg（JPEG圖像）【PHP中為：image/pjpeg】
image/png（PNG圖像）【PHP中為：image/x-png】
video/mpeg（MPEG動畫）
application/octet-stream（任意的二進制數(shù)據(jù)）
application/pdf（PDF文檔）
application/msword（Microsoft Word文件）
message/rfc822（RFC 822形式）
multipart/alternative（HTML郵件的HTML形式和純文本形式浦楣，相同內(nèi)容使用不同形式表示）
application/x-www-form-urlencoded（使用HTTP的POST方法提交的表單）
multipart/form-data（同上，但主要用于表單提交時伴隨文件上傳的場合）
