How to send an email with attachments in Go

我发现了这个库，并成功地在一封空邮件中发送了附件，但无法将文本和附件组合在一起。

如何实现这个功能？

我自己最终实现了它：https://github.com/scorredoira/email
使用非常简单：
m := email.NewMessage("Hi", "this is the body")
m.From = "from@example.com"
m.To = []string{"to@example.com"}
err := m.Attach("picture.png")
if err != nil {
log.Println(err)
}
err = email.Send("smtp.gmail.com:587", smtp.PlainAuth("", "user", "password", "smtp.gmail.com"), m)
英文:
I ended up implementing it myself: https://github.com/scorredoira/email
Usage is very simple:
m := email.NewMessage("Hi", "this is the body")
m.From = "from@example.com"
m.To = []string{"to@example.com"}
err := m.Attach("picture.png")
if err != nil {
log.Println(err)
}
err = email.Send("smtp.gmail.com:587", smtp.PlainAuth("", "user", "password", "smtp.gmail.com"), m)

我为此目的创建了gomail。它支持附件、多部分邮件和非ASCII字符的编码。它有很好的文档和测试。
这是一个示例：
package main
func main() {
m := gomail.NewMessage()
m.SetHeader("From", "alex@example.com")
m.SetHeader("To", "bob@example.com", "cora@example.com")
m.SetAddressHeader("Cc", "dan@example.com", "Dan")
m.SetHeader("Subject", "Hello!")
m.SetBody("text/html", "Hello <b>Bob</b> and <i>Cora</i>!")
m.Attach("/home/Alex/lolcat.jpg")
d := gomail.NewPlainDialer("smtp.example.com", 587, "user", "123456")
// 将邮件发送给Bob、Cora和Dan。
if err := d.DialAndSend(m); err != nil {
panic(err)
}
}
英文:
I created gomail for this purpose. It supports attachments as well as multipart emails and encoding of non-ASCII characters. It is well documented and tested.
Here is an example:
package main
func main() {
m := gomail.NewMessage()
m.SetHeader("From", "alex@example.com")
m.SetHeader("To", "bob@example.com", "cora@example.com")
m.SetAddressHeader("Cc", "dan@example.com", "Dan")
m.SetHeader("Subject", "Hello!")
m.SetBody("text/html", "Hello <b>Bob</b> and <i>Cora</i>!")
m.Attach("/home/Alex/lolcat.jpg")
d := gomail.NewPlainDialer("smtp.example.com", 587, "user", "123456")
// Send the email to Bob, Cora and Dan.
if err := d.DialAndSend(m); err != nil {
panic(err)
}
}

我更喜欢使用https://github.com/jordan-wright/email来处理电子邮件。
它支持附件。

在SMTP协议中，附件是使用多部分MIME消息发送的。
所以我建议你简单地：
- 创建一个
MultipartMessage - 将你的文本作为第一部分设置为
TextMessage（使用"Content-Type", "text/plain"） - 使用
AddPart将你的附件添加为部分。
英文:
Attachements in the SMTP protocol are sent using a Multipart MIME message.
So I suggest you simply
-
create a
MultipartMessage -
set your text in the fist part as a
TextMessage(with"Content-Type", "text/plain") -
add your attachements as parts using
AddPart.
