前言
本文使用 Gmail 提供的 SMTP server 做為範例。
前置作業
首先,到 Google 帳戶的「安全性」頁面,設定以下:
- 啟用兩步驟驗證(2-Step Verification)
- 新增應用程式密碼(App passwords)
實作
新增 main.go
檔:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30
| package main
import ( "log" "net/smtp" )
func main() { addr := "smtp.gmail.com:587" host := "smtp.gmail.com" identity := "" from := "" password := "" to := "" subject := "This is an example email" body := "Hello" msg := "From:" + from + "\r\n" + "To:" + to + "\r\n" + "Subject:" + subject + "\r\n" + body
err := smtp.SendMail( addr, smtp.PlainAuth(identity, from, password, host), from, []string{to}, []byte(msg), )
if err != nil { log.Println(err) } }
