一、MIME TYPE描述
多用途網際網路郵件擴充套件(MIME,Multipurpose Internet Mail Extensions)是一個網際網路標準,它擴充套件了電子郵件標準,使其能夠支援非ASCII字元、二進制格式附件等多種格式的郵件訊息。
內容型別(Content-Type),這個頭部領域用於指定訊息的型別。一般以下面的形式出現。[type]/[subtype]
type有下面的形式。
Text:用於標準化地表示的文字資訊,文字訊息可以是多種字符集和或者多種格式的;
Multipart:用於連線訊息體的多個部分構成一個訊息,這些部分可以是不同型別的資料;
Application:用於傳輸應用程式資料或者二進制資料;
Message:用於包裝一個E-mail訊息;
Image:用於傳輸靜態圖片資料;
Audio:用於傳輸音訊或者音聲資料;
Video:用於傳輸動態影像資料,可以是與音訊編輯在一起的視訊資料格式。
subtype 用於指定type的詳細形式。content-type/subtype配對的集合和與此相關的引數,將隨著時間而增長。爲了確保這些值在一個有序而且公開的狀態下開發,MIME使用Internet Assigned Numbers Authority (IANA)作為中心的序號產生器制來管理這些值。常用的subtype值如下所示:
text/plain(純文字)
text/html(HTML文件)
application/xhtml+xml(XHTML文件)
image/gif(GIF影象)
image/jpeg(JPEG影象)【PHP中為:image/pjpeg】
image/png(PNG影象)【PHP中為:image/x-png】
video/mpeg(MPEG動畫)
application/octet-stream(任意的二進制資料)
application/msword(Microsoft Word檔案)
message/rfc822(RFC 822形式)
multipart/alternative(HTML郵件的HTML形式和純文字形式,相同內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,但主要用於表單提交時伴隨檔案上傳的場合)
