Contact form mail handler example for go on appengine
问题
令我惊讶的是，我没有找到一个关于Go语言的联系表单邮件处理器的示例。我今天不想重复造轮子，是否有现成的示例可用？
编辑：（剪切和粘贴的答案）
package binimport ("fmt""net/http"netMail "net/mail""appengine""appengine/mail")func contact(w http.ResponseWriter, r *http.Request) {c := appengine.NewContext(r)name := r.FormValue("name")email := r.FormValue("email")subject := r.FormValue("subject")message := r.FormValue("message")msg := &mail.Message{Sender: name + " <...@yourappid.appspotmail.com>",To: []string{"...@..."},ReplyTo: email,Subject: subject,Body: message,Headers: netMail.Header{"On-Behalf-Of": []string{email},},}if err := mail.Send(c, msg); err != nil {c.Errorf("Couldn't send email: %v", err)fmt.Fprint(w, "Mail NOT send! Error")} else {fmt.Fprint(w, "Mail send.")}}
注意：
1）如果Sender和To不同，ReplyTo只在Gmail中起作用。
2）Sender应该在Google Cloud控制台中拥有管理员角色，或者是something@yourappid.appspotmail.com。

To my surprise I did not find a contact form mail handler example for go? I don't feel like making a wheel today, are there examples available?
EDIT: (cut and paste answer)
package binimport ("fmt""net/http"netMail "net/mail""appengine""appengine/mail")func contact(w http.ResponseWriter, r *http.Request) {c := appengine.NewContext(r)name := r.FormValue("name")email := r.FormValue("email")subject := r.FormValue("subject")message := r.FormValue("message")msg := &mail.Message{Sender: name + " <...@yourappid.appspotmail.com>",To: []string{"...@..."},ReplyTo: email,Subject: subject,Body: message,Headers: netMail.Header{"On-Behalf-Of": []string{email},},}if err := mail.Send(c, msg); err != nil {c.Errorf("Couldn't send email: %v", err)fmt.Fprint(w, "Mail NOT send! Error")}else{fmt.Fprint(w, "Mail send.")}}
NOTE:
-
ReplyToonly works in gmail ifSenderandToare different. -
Sendershould have admin role in google cloud console orsomething@yourappid.appspotmail.com.

这很可能失败是因为Sender只能是以下两种情况之一：
- 你的应用程序开发者的电子邮件，或者
something@yourappid.appspotmail.com
我建议你硬编码发送者的电子邮件，并在其中使用On-Behalf-Of头部，其中包括原始发送者的姓名/电子邮件。
另外，WriteString只接受一个string，而不是[]string切片。
对于你的示例，最小的修改应该是：
…msg := &mail.Message{Sender: name + " <developer@yourapp.com>",To: []string{"...@gmail.com"},Subject: subject,Body: message,Headers: netMail.Header{"On-Behalf-Of": []string{email},},}…
另外，你需要确保用户的姓名实际上不包含电子邮件地址。那可能会给你带来问题...
最好按照 @elithrar 的建议验证你的表单。
英文:
This is most likely failing because the Sender can only be
- an email of a developer of you app, or
something@yourappid.appspotmail.com
I suggest that you hard-code the sender's email, and use the On-Behalf-Of header in which you include the original sender's name/email.
Also, WriteString accepts a single string, not a []string slice.
The minimum modifications for your example would be:
…msg := &mail.Message{Sender: name + " <developer@yourapp.com>",To: []string{"...@gmail.com"},Subject: subject,Body: message,Headers: netMail.Header{"On-Behalf-Of": []string{email},},}…
Also, you'll need to make sure the user's name doesn't actually contain an email address. That could cause you problems…
The best would be to do as @elithrar suggested and validate your form.
