好久没有更新博客了,这次又带来了一段GO语言的代码(没办法,只会写代码了)。
Go语言邮件群发器 main.go
// Multi-SendEmail project main.go package main import ( "bufio" "errors" "fmt" "io" "io/ioutil" "net/smtp" "os" "strings" "time" ) 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 string if mailtype == "html" { content_type = "Content-Type: text/html;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 readLine2Array(filename string) ([]string, error) { result := make([]string, 0) file, err := os.Open(filename) if err != nil { return result, errors.New("Open file failed.") } defer file.Close() bf := bufio.NewReader(file) for { line, isPrefix, err1 := bf.ReadLine() if err1 != nil { if err1 != io.EOF { return result, errors.New("ReadLine no finish") } break } if isPrefix { return result, errors.New("Line is too long") } str := string(line) result = append(result, str) } return result, nil } func main() { fmt.Println("start...") user := "邮箱@qq.com" password := "密码" host := "smtp.qq.com:25" //QQ为例 subject := "邮件标题" sendTo, err := readLine2Array("send.txt") if err != nil { fmt.Println(err) return } content, err := ioutil.ReadFile("email.txt") if err != nil { fmt.Println(err) return } body := string(content) for i := 0; i < len(sendTo); i++ { to := sendTo[i] fmt.Println("Send email to " + to) err = SendMail(user, password, host, to, subject, body, "html") if err != nil { fmt.Println("send mail error!") fmt.Println(err) i-- time.Sleep(600 * time.Second) } else { fmt.Println("send mail success!") } } }
使用说明:
编译出exe文件,把要发送的邮箱一行一个放入send.txt中,邮件内容放入email.txt中(HTML格式),运行。
这代码我也有在用,有很多不灵活的地方,仅供参考。
