Is it possible to create email templates with CSS in Google App Engine Go?
问题
我正在创建一个使用GAE Golang应用程序，用于通知用户系统中正在发生的事情。由于我希望邮件看起来漂亮，所以我已经在使用HTMLBody。然而，随着我创建越来越复杂的邮件，我想开始使用类似html/template的东西来创建带有CSS等漂亮外观的邮件。然而，我不确定如何使用Template.Execute将其转换为可以发送的HTMLBody字符串。
我该如何使用类似html/template的东西来创建HTML邮件，并与appengine/mail一起使用？

I am creating a GAE Golang application that will be notifying users of what is happening in the system. Since I want the emails to look nice, I am already using HTMLBody. However, as I'm creating more and more complex emails, I would like to start using something like html/template to crease nice looking emails with CSS and so forth. However, I'm not sure how I can do Template.Execute to turn it into HTMLBody string that can be sent.
How can I use something like html/template to create HTML emails to use with appengine/mail ?

你可以将模板渲染到一个临时的字节缓冲区中，像这样：
var tmpl = template.Must(template.ParseFiles("templates/email.html"))
buff := new(bytes.Buffer)
if err = tmpl.Execute(buff, struct{ Name string }{"Juliet"}); err != nil {
panic(err.Error())
}
msg := &mail.Message{
Sender: "romeo@montague.com",
To: []string{"Juliet <juliet@capulet.org>"},
Subject: "See you tonight",
Body: "...you put here the non-HTML part...",
HTMLBody: buff.String(),
}
c := appengine.NewContext(r)
if err := mail.Send(c, msg); err != nil {
c.Errorf("Alas, my user, the email failed to sendeth: %v", err)
}
英文:
You can render the template to a temporary byte buffer, like this:
var tmpl = template.Must(template.ParseFiles("templates/email.html"))
buff := new(bytes.Buffer)
if err = tmpl.Execute(buff, struct{ Name string }{"Juliet"}); err != nil {
panic(err.Error())
}
msg := &mail.Message{
Sender: "romeo@montague.com",
To: []string{"Juliet <juliet@capulet.org>"},
Subject: "See you tonight",
Body: "...you put here the non-HTML part...",
HTMLBody: buff.String(),
}
c := appengine.NewContext(r)
if err := mail.Send(c, msg); err != nil {
c.Errorf("Alas, my user, the email failed to sendeth: %v", err)
}
