/*
遇到的问题:

1、body := ``,这里用的是反单引号,而非单引号;

2、err != nil,golang的nil在概念上和其它语言的null、None、nil、NULL一样,都指代零值或空值。nil是预先说明的标识符,也即通常意义上的关键字。在golang中,nil只能赋值给指针、channel、func、interface、map或slice类型的变量。如果未遵循这个规则,则会引发panic。对此官方有明确的说明:http://pkg.golang.org/pkg/builtin/#Type

3、参数auth,auth := smtp.PlainAuth("", user, password, hp[0])

4、强制类型转换,msg := []byte("To: " + to + "\r\nFrom: " + user + ">\r\nSubject: " + "\r\n" + content_type + "\r\n\r\n" + body)

5、多个邮箱:send_to := strings.Split(to, ";")*/
