网上能找到使用golang 发送邮件和发送加密邮件的教程。发送简单的文本邮件很是简单,但遇到须要发送附件时就基本要靠github.com/scorredoira/email。git
若是要发送加密带附件的邮件,邮件构造和加密处理加起来就显得代码有点杂。所以就本身封装了ssl
部分。固然,邮件构造就再也不重复造轮子了,仍是使用这个库github.com/scorredoira/email。github
用的是aliyun邮箱作测试。加密和非加密的区别就在于使用的时25
端口仍是465
端口。golang
package emailagent_test import ( "net/mail" "testing" "github.com/scorredoira/email" "github.com/zhnxin/emailagent" ) func generateEmail() (*email.Message, error) { // compose the message m := email.NewMessage("Hi", "this is the body") //这里显示的发件人名和邮箱,随便写不会影响邮件发送 m.From = mail.Address{Name: "nic name", Address: "username@aliyun.com"} m.To = []string{"target@aliyun.com"} // add attachments if err := m.Attach("agent.go"); err != nil { return nil, err } // add headers m.AddHeader("X-CUSTOMER-id", "xxxxx") return m, nil } func TestSSL(t *testing.T) { msg, err := generateEmail() if err != nil { t.Fatal(err) } agent := emailagent.New("exmaple@aliyun.com", "password", "smtp.aliyun.com", 465, true) //agent := emailagent.NewWithIdentify("identify","exmaple@aliyun.com", "password", "smtp.aliyun.com", 465, true) if err = agent.SendEmail(msg); err != nil { t.Fatal(err) } } func TestPlainAuth(t *testing.T) { msg, err := generateEmail() if err != nil { t.Fatal(err) } agent := emailagent.New("exmaple@aliyun.com", "password", "smtp.aliyun.com", 25, false) //agent := emailagent.NewWithIdentify("identify","exmaple@aliyun.com", "password", "smtp.aliyun.com", 25, false) if err = agent.SendEmail(msg); err != nil { t.Fatal(err) } }
