最近看了下go发送smtp邮件,于是总结一下
简单示例
先上一个最简单的代码 (网上搂的代码改了改)
package main import ( "fmt" "net/smtp" ) const ( // 邮件服务器地址 SMTP_MAIL_HOST = "smtp.qq.com" // 端口 SMTP_MAIL_PORT = "587" // 发送邮件用户账号 SMTP_MAIL_USER = "1348581672@qq.com" // 授权密码 SMTP_MAIL_PWD = "xxxx" // 发送邮件昵称 SMTP_MAIL_NICKNAME = "lewis" ) func main() { //声明err, subject,body类型,并为address,auth以及contentType赋值, //subeject是主题,body是邮件内容, address是收件人 var err error var subject, body string address := "lewissunp@outlook.com" auth := smtp.PlainAuth("", SMTP_MAIL_USER, SMTP_MAIL_PWD, SMTP_MAIL_HOST) contentType := "Content-Type: text/html; charset=UTF-8" //要发送的消息,可以直接写在[]bytes里,但是看着太乱,因此使用格式化 s := fmt.Sprintf("To:%s\r\nFrom:%s<%s>\r\nSubject:%s\r\n%s\r\n\r\n%s", address, SMTP_MAIL_NICKNAME, SMTP_MAIL_USER, subject, contentType, body) msg := []byte(s) //邮件服务地址格式是"host:port",因此把addr格式化为这个格式,直接赋值也行。 addr := fmt.Sprintf("%s:%s", SMTP_MAIL_HOST, SMTP_MAIL_PORT) //发送邮件 err = smtp.SendMail(addr, auth, SMTP_MAIL_USER, []string{address}, msg) if err != nil { fmt.Println(err) } else { fmt.Println("send email succeed") } }
收到邮件截图
简要说明
稍加改进
我们来加点常用的功能
package main import ( "fmt" "net/smtp" ) const ( // 邮件服务器地址 SMTP_MAIL_HOST = "smtp.qq.com" // 端口 SMTP_MAIL_PORT = "587" // 发送邮件用户账号 SMTP_MAIL_USER = "1348581672@qq.com" // 授权密码 SMTP_MAIL_PWD = "jhguvicvhrnwgaeh" // 发送邮件昵称 SMTP_MAIL_NICKNAME = "lewis" ) func main() { address := []string{"norton_s@qq.com", "lewissunp@outlook.com"} subject := "test mail" body := `<br>hello!</br> <br>this is a test email, pls ignore it.</br>` SendMail(address, subject, body) } func SendMail(address []string, subject, body string) (err error) { // 认证, content-type设置 auth := smtp.PlainAuth("", SMTP_MAIL_USER, SMTP_MAIL_PWD, SMTP_MAIL_HOST) contentType := "Content-Type: text/html; charset=UTF-8" // 因为收件人,即address有多个,所以需要遍历,挨个发送 for _, to := range address { s := fmt.Sprintf("To:%s\r\nFrom:%s<%s>\r\nSubject:%s\r\n%s\r\n\r\n%s", to, SMTP_MAIL_NICKNAME, SMTP_MAIL_USER, subject, contentType, body) msg := []byte(s) addr := fmt.Sprintf("%s:%s", SMTP_MAIL_HOST, SMTP_MAIL_PORT) err = smtp.SendMail(addr, auth, SMTP_MAIL_USER, []string{to}, msg) if err != nil { return err } } return err }
