PHPMailer，AddStringAttachment和数据URI方案 [英] PHPMailer, AddStringAttachment and Data URI Scheme

问题描述

我已使用toDataURL()($contact_image_data)将canvas元素的内容转换为数据(URI方案)，我想通过电子邮件将其作为附件发送.当前，这是我设置PHPMailer的方式:

I have converted the contents of a canvas element to data (URI Scheme) using toDataURL() ($contact_image_data) and I want to send this via email as an attachment. This is currently how I have PHPMailer set up:

$contact_image_data="data:image/png;base64,iVBORw0KGgo[...]";
$filename="test.png"; 
$encoding = "base64"; 
$type = "image/png";
$mail->AddStringAttachment($contact_image_data, $filename, $encoding, $type);   

我想知道这是否真的可能，如果可以的话，我错过了哪些步骤.

I am wondering if this is actually possible, and if so, what steps I am missing.

我可以发送电子邮件，附加一个名为"test.png"的文件，其中包含$contact_image_data的内容，但实际上并没有创建图像.

I can send an email, attach a file named "test.png" which contains the contents of $contact_image_data, but it doesn’t actually create an image.

任何帮助将不胜感激.

推荐答案

是的，应该可行.您要使用"image/png" MIME类型调用toDataURL()以便它知道如何输出吗?

Yes it should be possible. Are you calling toDataURL() with the 'image/png' MIME type so it knows how to output it?

尝试将脚本分为两个部分-确保您确实有PNG，然后尝试邮寄该邮件.

Try breaking your script into two components - make sure you really have a PNG then try mailing it.

例如，编写时会在计算机上打开test.png吗?.

For example, will test.png open on your computer when written?..

<?php
$contact_image_data="data:image/png;base64,iVBORw0KGgo[...]";
$fp = fopen('test.png', 'w');
fwrite($fp, $contact_image_data);
fclose($fp);
?>
