Question

我想发送带有附加图片的邮件，并将此图片嵌入到html中。作为标记的来源，我应该写什么，是否有任何缺少的标题部分，如content_type？

当我进行真正的测试时，我会发送邮件到我的Gmail帐户。我可以看到有一个名为“未命名”的附件，即使我下载也无法显示图像。

require 'pony'
Pony.override_options = { :via => :test }
Pony.mail(
    :to => 'foo@bar',
    :from => 'abc@abc.com',
    :subject => 'test123',
    :body =>   "<h1><strong>Dear X, check the newsletter ,<br></strong></h1> <img src='attached image' />",
    :attachments => {"happy_image.jpg" => File.read("happy_image.jpg")}
)
puts Mail::TestMailer.deliveries

输出：

Answer 1

您应该能够对图像进行BASE64编码，并将结果字符串用作\d+\s\d+(\s\d+)+标记的src。

例如：

img

另外，请确保将您的内容类型设置为<img src="data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAWQAAAD8CAYAAAB..."/>而不是text/html。看邮件，它似乎设置为后者，因此图像不会渲染，标签呈现为文本。将以下内容添加到您的参数中以使用text/plain内容类型：

text/html

在Ruby中发送带嵌入图像的邮件
