我想创建包含多个附件的.eml
格式的电子邮件文件。附件已生成且附件内容正确。但附件始终以 .dat
格式出现,文件名为“ATT00001”、“ATT0002”等
目前我正在遵循 this stackoverflow question 中给出的解决方案我的代码如下
PHP
foreach($reports as $pdf){
$attachment = file_get_contents("auto_report_attachments\\Template_Attachment.eml");
$attachment = str_replace("TEMPLATE_MIME_TYPE", $pdf['type'], $attachment);
$attachment = str_replace("TEMPLATE_FILE_NAME", $pdf['filename'], $attachment);
$attachment = str_replace("TEMPLATE_ATTACHMENT_CONTENT", base64_encode($pdf['file']), $attachment);
$content .= $attachment;
unset($attachment);
}
模板附件
--080107000800000609090108
Content-Type: "TEMPLATE_MIME_TYPE"
name="TEMPLATE_FILE_NAME"
Content-Transfer-Encoding: base64
Content-Disposition: attachment;
filename="TEMPLATE_FILE_NAME"
TEMPLATE_ATTACHMENT_CONTENT
$content
是上面链接中描述的主要电子邮件 header 和正文。我的 .eml
文件看起来像;

上面的 base64
内容在通过选择要使用 pdf Reader
打开的文件打开时,在 pdf
文件中提供了正确的内容。但文件不是 .pdf
格式。 .xls
、.doc
和所有其他文件类型也是如此。所有文件均采用 .dat
格式,具有标准命名而不是指定名称。
请帮助我解决此附件问题,该附件来自具有指定文件名的所需文件类型
。
注意:示例 .eml
文件中的 base64
内容被截断
最佳答案
我自己找到了答案..!! Template_Attachment
的头部应该如下所示
--080107000800000609090108
Content-Type: TEMPLATE_MIME_TYPE;name="TEMPLATE_FILE_NAME"
Content-Transfer-Encoding: base64
Content-Disposition: attachment;filename="TEMPLATE_FILE_NAME"
TEMPLATE_ATTACHMENT_CONTENT
在这种情况下,080107000800000609090108
是边界,在所有附件的末尾,应该有另一个 080107000800000609090108
来结束电子邮件。
希望有一天这会对某人有所帮助:-)
PS:所以实际的 .eml
文件看起来像下面这样完美地工作

关于php - 附件名称和文件扩展名在电子邮件 *.eml 中不起作用,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/16032713/
