GoLang越来越被看好，流行只是时间的问题了，闲暇时间玩玩Go。
下面是发送邮件的demo，替换自己的邮箱，完全可以正常跑起来，用的是net/smtp包：
package main
import (
"fmt"
"net/smtp"
"strings"
)
func SendToMail(user, password, host, to, subject, body, mailtype string) error {
hp := strings.Split(host, ":")
auth := smtp.PlainAuth("", user, password, hp[0])
var content_type string
if 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 + "\r\nSubject: " + subject + "\r\n" + content_type + "\r\n\r\n" + body)
err := smtp.SendMail(host, auth, user, []string{to}, msg)
return err
}
func main() {
user := "591592159@qq.com"
password := "********"
host := "smtp.qq.com:587"
to := "591592159@qq.com"
subject := "使用Golang发送邮件"
body := `
<html>
<body>
<h3>
Test send to emailTest send to email
</h3>
</body>
</html>
`
fmt.Println("send email")
err := SendToMail(user, password, host, to, subject, body, "html")
if err != nil {
fmt.Println("Send mail error!")
fmt.Println(err)
} else {
fmt.Println("Send mail success!")
}
}
GoLang的基础包还是挺多的，也有github上的各种库，使用很方便！
