Golang implements the method of sending e-mail through SMTP _golang

The example in this article describes the Golang implementation method for sending e-mail messages through SMTP. Share to everyone for your reference, specific as follows:

Today wrote a company's mail to send a background service, PHP only need to put the mail into the database, and then Golang write the mailservice will mail sent out. The company's code does not send out, thinking with the business logic of the company, I sorted out the code for your reference. hehe

Copy Code code as follows:

Package Main
Import (
"FMT"
"Net/mail"
"Net/smtp"
"Encoding/base64"
)
Func Main () {
B64: = base64. Newencoding ("abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz0123456789+/")
Host: = "smtp.mail.com"
Email: = "mail1@mail.com"
Password: = "password"
Toemail: = "mail2@mail.com"
From: = Mail. address{"sender", email}
To: = Mail. address{"Receiver", toemail}
Header: = Make (map[string]string)
Header[' from '] = from. String ()
Header["to"] = to. String ()
header["Subject"] = FMT. Sprintf ("=? UTF-8? B?%s?= ", b64. Encodetostring ([]byte ("Mail Heading 2"))
header["mime-version"] = "1.0"
header["Content-type"] = "text/html; Charset=utf-8 "
header["content-transfer-encoding"] = "base64"
Body: = "I am an email!golang issued.";
Message: = ""
For k, V: = Range Header {
Message + + FMT. Sprintf ("%s:%s\r\n", K, V)
}
Message + = "\ r \ n" + b64. Encodetostring ([]byte (body))
Auth: = SMTP. Plainauth (
"",
Email
Password
Host
)
ERR: = SMTP. SendMail (
host+ ": 25",
Auth
Email
[]string{to. Address},
[]byte (Message),
)
If Err!= nil {
Panic (ERR)
}
}
