4.quoted-printable:该编码方式用于编码8位数据,但将所有非ASCII字符以及特殊字符进行编码,以确保它们能够正确传输。这种编码方式常用于电子邮件。 5.base64:用于将8位二进制数据编码成ASCII字符集中的可打印字符,以便传输非文本数据,如图片或二进制文件。base64编码会引入一些额外的字符,但它具有广泛的应用。©...
Content-Transfer-Encoding是指在传输MIME消息体时所采用的编码方式。它告诉接收方如何解码消息体以获取原始数据。常见的Content-Transfer-Encoding包括7bit、8bit、binary、base64和quoted-printable等。具体含义如下: 7bit:表示消息体中只包含7位的ASCII字符,不需要进行编码转换。 8bit:表示消息体中可能包含8位字符,但...
Base64将3个字节转变为4个字节,因此,编码后的代码量(以字节为单位,下同)约比编码前的代码量多了1/3。之所以说是“约”,是因为如果代码量正好是3的整数倍,那么自然是多了1/3。但如果不是呢? 细心的人可能已经注意 到了,在The Base64 Alphabet中的最后一个有一个(pad) =字符。这个字符的目的就是用来处理...
5.2. Base64 Content-Transfer-Encoding The Base64 Content-Transfer-Encoding is designed to represent arbitrary sequences of octets in a form that need not be humanly readable. The encoding and decoding algorithms are simple, but the encoded data are consistently only about 33 percent larger than ...

MIME 定義兩種編碼方法:Base64 與QP(Quote-Printable), 兩者使用時機不同,QP 的規則是對於資料中的7bits無須重複encode, 僅8bits資料轉成7bits。QP編碼適用於非US-ASCII的文字內容, 例如我們的中文檔案,而Base64的編碼規則,是將整個檔案重新編碼, 編成7bits,它是用於傳送binary檔案時使用。 由於編碼的方式不同...
While there are five content-transfer-encoding values defined, along with the extensible X-token, the base64 and quoted-printable are the only actual encoding schemes defined by Multipurpose Internet Mail Extensions (MIME). These two schemes offer the extremes in the tradeoff between the need for...
