ColdFusion cfmail 主题行中的特殊字符

发布于 2025-01-07 09:32:46 字数 527 浏览 0 评论 0原文

邮件主题行中的特殊字符将转换为问号或方框。

我尝试将主题行的动态字符串包装在 URLEncodedFormat 中，但最终徒劳无功。

<cfset strSubject= URLEncodedFormat(s)>
<cfmail 
  from="[email protected]" 
  to="[email protected]" 
  subject="#strSubject#"         
  type="html"
>
  #testText#
</cfmail>

原文

Special characters in the subject line of the mail getting converted in to question marks or boxes.

I have tried to wrap the dynamic string of the subject line in URLEncodedFormat , however ended up in vain.

<cfset strSubject= URLEncodedFormat(s)>
<cfmail 
  from="[email protected]" 
  to="[email protected]" 
  subject="#strSubject#"         
  type="html"
>
  #testText#
</cfmail>

假设特殊字符是 unicode 字符，您必须将字符串编码为 base64 格式并在主题行中使用它。像这样，

<cfset strSubject="Demande d’chantillons supplémentaires">
<cfset strSubject=ToBase64(strSubject, "utf-8")>

<cfmail from="[email protected]" to="[email protected]" subject="=?utf-8?B?#strSubject#?=" type="html">
    #testText#
</cfmail>

主题行的格式必须为 =????=

? 和 = 为必填项。

MIME - 编码字

“字符集”可以是向 IANA 注册的任何字符集。通常
它将与消息正文具有相同的字符集。
“编码”可以是“Q”，表示类似的 Q 编码
到引用打印编码，或“B”表示base64编码。
“编码文本”是Q编码或base64编码文本。

Assuming the special characters are unicode charactes, you will have to encode the string to a base64 format and use that in the subject line. Like this,

<cfset strSubject="Demande d’chantillons supplémentaires">
<cfset strSubject=ToBase64(strSubject, "utf-8")>

<cfmail from="[email protected]" to="[email protected]" subject="=?utf-8?B?#strSubject#?=" type="html">
    #testText#
</cfmail>

The subject line must be in the format =?<charset>?<encoding>?<encoded text>?=

The ? and = are required.

MIME - Encoded Word

"charset" may be any character set registered with IANA. Typically
it would be the same charset as the message body.
"encoding" can be either "Q" denoting Q-encoding that is similar
to the quoted-printable encoding, or "B" denoting base64 encoding.
"encoded text" is the Q-encoded or base64-encoded text.
