发邮件功能可以调用比如: qq  163 新浪的邮箱进行发送 , 使用go-smtp这个类库来发送比较简单 , 例如下面的例子:

 

package tools

import (
    "github.com/emersion/go-sasl"
    "github.com/emersion/go-smtp"
    "strings"
)

func Send(server string,from string,password string,to []string,subject string,body string)error{
    auth := sasl.NewPlainClient("", from, password)
    msg := strings.NewReader(
        "From: "+from+"\r\n"+
            "To: "+strings.Join(to,",")+"\r\n"+
        "Subject: "+subject+"\r\n" +
        "\r\n" +
        body+"\r\n")
    err := smtp.SendMail(server, auth, from, to, msg)
    if err != nil {
        return err
    }
    return nil
}
