问题描述
我希望有人可以帮助我在下面的代码中做错了什么 - 我的电子邮件被发送，大多数电子邮件客户端（gmail web，android）中的图像都已正确插入，但是它不能正常呈现一个iphone / ipad：只显示最后附加的图片，没有显示任何html内容或文本内容。我理解每个电子邮件客户端都会解释并提供不同的有效载荷，我不知道如何使其在iphone上工作。任何帮助赞赏！
ruby code：
require'mail'
def inline_body_with_attachments（html，附件）
attachments.each do | attachment |
if（html =〜/#{attachment.filename}/）
html = html.sub（attachment.filename，cid：＃{attachment.cid}）
end
end
return html
end
mail = Mail.new（{
：from =>[email protected]，
：to =>[email protected]，
：subject =>带内联图片的html电子邮件
}）
text_part =邮件:: Part.new do
bodysome text
end
mail.text_part = text_part
＃加载附件
附件=image.png
mail.attachments [attachment] = File.read（attachment）
inline_html = inline_body_with_attachments（< b>内联图像< / b>< img src ='image.png'/>，mail.attachments）
html_part = Mail :: Part.new do
content_type'text / html; charset = UTF-8'
body inline_html
end
mail.html_part = html_part
mail.deliver！

解决方案
为了wrok on iphone，我不得不将图像的html内容包装到他们自己的多部分/相关的部分。
require'mail'
def inline_body_with_attachments（html，附件）
attachments.each do | attachment |
if（html =〜/#{attachment.filename}/）
html = html.sub（attachment.filename，cid：＃{attachment.cid}）
end
end
return html
end
mail = Mail.new（{
：from =>[email protected]，
：to =>[email protected]，
：subject =>带有attachment- raw4的测试邮件，
：content_type =>'multipart / alternative'
}）
text_part = Mail :: Part.new do
bodysome text
end
mail.add_part（text_part）
other_part = Mail :: Part.new do
content_type'multipart / related;'
end
＃加载附件
附件=image.png
＃mail.attachments [attachment] = File.read（附件）
other_part.add_file（附件）
inline_html = inline_body_with_attachments（< b> ;一个内联图像< / b>< img src ='image.png'/>，other_part.attachments）
html_part = Mail :: Part.new do
conte nt_type'text / html; charset = UTF-8'
body inline_html
end
other_part.add_part（html_part）
mail.add_part（other_part）
邮件。交付！
I was hoping someone could help me out what I'm doing wrong in the below code - my email get sent, with the image inlined properly in most email client (gmail web, android), but it does not render properly on an iphone/ipad: only the last attached picture is displayed, without any html content or text content displayed. I understand every email client interprets and renders the payload differently, I don't know how to make it work on an iphone.
Any help appreciated!
ruby code:
require 'mail'
def inline_body_with_attachments(html, attachments)
attachments.each do |attachment|
if (html =~ /#{attachment.filename}/)
html = html.sub(attachment.filename, "cid:#{attachment.cid}")
end
end
return html
end
mail = Mail.new({
:from => "[email protected]",
:to => "[email protected]",
:subject => "html email with inline images"
})
text_part = Mail::Part.new do
body "some text"
end
mail.text_part = text_part
# Load the attachments
attachment = "image.png"
mail.attachments[attachment] = File.read(attachment)
inline_html = inline_body_with_attachments("<b>An inline image</b><img src='image.png'/>", mail.attachments)
html_part = Mail::Part.new do
content_type 'text/html; charset=UTF-8'
body inline_html
end
mail.html_part = html_part
mail.deliver!

解决方案
In order to wrok on the iphone, I had to wrap the html content with the image into their own multipart/related part.
require 'mail'
def inline_body_with_attachments(html, attachments)
attachments.each do |attachment|
if (html =~ /#{attachment.filename}/)
html = html.sub(attachment.filename, "cid:#{attachment.cid}")
end
end
return html
end
mail = Mail.new({
:from => "[email protected]",
:to => "[email protected]",
:subject => "test mail with attachment- raw4",
:content_type => 'multipart/alternative'
})
text_part = Mail::Part.new do
body "some text"
end
mail.add_part( text_part)
other_part = Mail::Part.new do
content_type 'multipart/related;'
end
# Load the attachments
attachment = "image.png"
#mail.attachments[attachment] = File.read(attachment)
other_part.add_file(attachment)
inline_html = inline_body_with_attachments("<b>An inline image</b><img src='image.png'/>", other_part.attachments)
html_part = Mail::Part.new do
content_type 'text/html; charset=UTF-8'
body inline_html
end
other_part.add_part(html_part)
mail.add_part(other_part)
mail.deliver!
