【go语言发送电子邮件】go语言版发送电子邮件

本文主要是介绍【go语言发送电子邮件】go语言版发送电子邮件，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

一、实现功能
用go语言发送一封邮件

二、实现源代码

package main
import ("net/smtp""fmt""strings"
)/**  user : example@example.com login smtp server user*  password: xxxxx login smtp server password*  host: smtp.example.com:port   smtp.163.com:25*  to: example@example.com;example1@163.com;example2@sina.com.cn;...*  subject:The subject of mail*  body: The content of mail*  mailtyoe: mail type html or text*/func SendMail(user, password, host, to, subject, body, mailtype string) error{hp := strings.Split(host, ":")auth := smtp.PlainAuth("", user, password, hp[0])var content_type stringif mailtype == "html" {content_type = "Content-Type: text/"+ mailtype + "; charset=UTF-8"}else{content_type = "Content-Type: text/plain" + "; charset=UTF-8"}msg := []byte("To: " + to + "\r\nFrom: " + user + "<"+ user +">\r\nSubject: " + subject + "\r\n" + content_type + "\r\n\r\n" + body)send_to := strings.Split(to, ";")err := smtp.SendMail(host, auth, user, send_to, msg)return err
}func main() {user := "此处填写qq邮箱账号"password := "此处填写qq邮箱授权码"host := "smtp.qq.com:587"to := "18720081236m@sina.cn"subject := "Test send email by golang"body := `
`fmt.Println("send email")err := SendMail(user, password, host, to, subject, body, "text")if err != nil {fmt.Println("send mail error!")fmt.Println(err)}else{fmt.Println("send mail success!")}}

运行效果

"D:\Program Files (x86)\JetBrains\Gogland 171.3780.106\bin\runnerw.exe" D:/Go\bin\go.exe run D:/Go/code/src/awesomeProject/go_email.go
send email
send mail success!Process finished with exit code 0

版本2（发送多个人，HTML格式）：

package main
import ("net/smtp""fmt""strings"
)/**  user : example@example.com login smtp server user*  password: xxxxx login smtp server password*  host: smtp.example.com:port   smtp.163.com:25*  to: example@example.com;example1@163.com;example2@sina.com.cn;...*  subject:The subject of mail*  body: The content of mail*  mailtyoe: mail type html or text*/func SendMail(user, password, host, to, subject, body, mailtype string) error{hp := strings.Split(host, ":")auth := smtp.PlainAuth("", user, password, hp[0])var content_type stringif mailtype == "html" {content_type = "Content-Type: text/"+ mailtype + "; charset=UTF-8"}else{content_type = "Content-Type: text/plain" + "; charset=UTF-8"}msg := []byte("To: " + to + "\r\nFrom: " + user + "<"+ user +">\r\nSubject: " + subject + "\r\n" + content_type + "\r\n\r\n" + body)send_to := strings.Split(to, ";")err := smtp.SendMail(host, auth, user, send_to, msg)return err
