关于python和php发送邮件

背景

突然想做一个能在手机上提示事件发生的东西，考虑了几种方式：

1. 写一个APP与服务器进行socket通信，每隔一定时间取信息，事件发生时提醒；
2. 利用短信，诸如SMS，飞信等；
3. 利用QQ，微信等通信工具提醒；
4. 服务器发送邮件到指定邮箱，然后手机上利用邮箱管理软件提醒；

斟酌一下，1太麻烦，2太费钱，3需要获取QQ，微信API，呃...找了下资料，还是太麻烦，4勉强还行，那就4吧。

python实现

网上找了个现成的，测试还可以用，就直接搬上来:

# coding=utf-8
import smtplib
from email.mime.text import MIMEText

mailto_list = ['XXXX@163.com']
mail_host = "smtp.163.com"
mail_user = "XXXX@163.com"
mail_pass = "XXXX"
mail_postfix = "163.com"


def send_mail(to_list, sub, content):
    me = "hello" + "<" + mail_user + "@" + mail_postfix + ">"
    msg = MIMEText(content, _subtype='plain', _charset='utf-8')
    msg['Subject'] = sub
    msg['From'] = "XXXXX@163.com"
    msg['To'] = ";".join(to_list)

    try:
        server = smtplib.SMTP()
        server.connect(mail_host)
        server.login(mail_user, mail_pass)
        server.sendmail(me, to_list, msg.as_string())
        server.close()
        return True
    except Exception, e:
        print str(e)
        return False


if __name__ == '__main__':
    if send_mail(mailto_list, "提示邮件", "测试一下!"):
        print "success"
    else:
        print "failed"

php实现

网上php版本有很多，但这个版本相对而言较为简洁，测试也可用。

    <?php
    $bfconfig = Array (
    'sitename' => 'YTNotice',
    );
    
    $mail = Array (
    'state' => 1,
    'server' => 'smtp.163.com',
    'port' => 25,
    'auth' => 1,
    'username' => 'xxxx@163.com',
    'password' => 'xxx',
    'charset' => 'utf-8',
    'mailfrom' => xxxx@163.com'
    );
    
    function sendmail($mail_to, $mail_subject, $mail_message) {
    
    global $mail, $bfconfig;
    
    date_default_timezone_set('PRC');
    
    $mail_subject = '=?'.$mail['charset'].'?B?'.base64_encode($mail_subject).'?=';
    $mail_message = chunk_split(base64_encode(preg_replace("/(^|(\r\n))(\.)/", "\1.\3", $mail_message)));
    
    $headers = "";
    $headers .= "MIME-Version:1.0\r\n";
    $headers .= "Content-type:text/html\r\n";
    $headers .= "Content-Transfer-Encoding: base64\r\n";
    $headers .= "From: ".$bfconfig['sitename']."<".$mail['mailfrom'].">\r\n";
    $headers .= "Date: ".date("r")."\r\n";
    list($msec, $sec) = explode(" ", microtime());
    $headers .= "Message-ID: <".date("YmdHis", $sec).".".($msec * 1000000).".".$mail['mailfrom'].">\r\n";
    
    if(!$fp = fsockopen($mail['server'], $mail['port'], $errno, $errstr, 30)) {
    exit("CONNECT - Unable to connect to the SMTP server");
    }
    
    stream_set_blocking($fp, true);
    
    $lastmessage = fgets($fp, 512);
    if(substr($lastmessage, 0, 3) != '220') {
    exit("CONNECT - ".$lastmessage);
    }
    
    fputs($fp, ($mail['auth'] ? 'EHLO' : 'HELO')." befen\r\n");
    $lastmessage = fgets($fp, 512);
    if(substr($lastmessage, 0, 3) != 220 && substr($lastmessage, 0, 3) != 250) {
    exit("HELO/EHLO - ".$lastmessage);
    }
    
    while(1) {
    if(substr($lastmessage, 3, 1) != '-' || empty($lastmessage)) {
    break;
    }
    $lastmessage = fgets($fp, 512);
    }
    
    if($mail['auth']) {
    fputs($fp, "AUTH LOGIN\r\n");
    $lastmessage = fgets($fp, 512);
    if(substr($lastmessage, 0, 3) != 334) {
    exit($lastmessage);
    }
    
    fputs($fp, base64_encode($mail['username'])."\r\n");
    $lastmessage = fgets($fp, 512);
    if(substr($lastmessage, 0, 3) != 334) {
    exit("AUTH LOGIN - ".$lastmessage);
    }
    
    fputs($fp, base64_encode($mail['password'])."\r\n");
    $lastmessage = fgets($fp, 512);
    if(substr($lastmessage, 0, 3) != 235) {
    exit("AUTH LOGIN - ".$lastmessage);
    }
    
    $email_from = $mail['mailfrom'];
    }
    
    fputs($fp, "MAIL FROM: <".preg_replace("/.*\<(.+?)\>.*/", "\\1", $email_from).">\r\n");
    $lastmessage = fgets($fp, 512);
    if(substr($lastmessage, 0, 3) != 250) {
    fputs($fp, "MAIL FROM: <".preg_replace("/.*\<(.+?)\>.*/", "\\1", $email_from).">\r\n");
    $lastmessage = fgets($fp, 512);
    if(substr($lastmessage, 0, 3) != 250) {
    exit("MAIL FROM - ".$lastmessage);
    }
    }
    
    foreach(explode(',', $mail_to) as $touser) {
    $touser = trim($touser);
    if($touser) {
    fputs($fp, "RCPT TO: <".preg_replace("/.*\<(.+?)\>.*/", "\\1", $touser).">\r\n");
    $lastmessage = fgets($fp, 512);
    if(substr($lastmessage, 0, 3) != 250) {
    fputs($fp, "RCPT TO: <".preg_replace("/.*\<(.+?)\>.*/", "\\1", $touser).">\r\n");
    $lastmessage = fgets($fp, 512);
    exit("RCPT TO - ".$lastmessage);
    }
    }
    }
    
    fputs($fp, "DATA\r\n");
    $lastmessage = fgets($fp, 512);
    if(substr($lastmessage, 0, 3) != 354) {
    exit("DATA - ".$lastmessage);
    }
    
    fputs($fp, $headers);
    fputs($fp, "To: ".$mail_to."\r\n");
    fputs($fp, "Subject: $mail_subject\r\n");
    fputs($fp, "\r\n\r\n");
    fputs($fp, "$mail_message\r\n.\r\n");
    $lastmessage = fgets($fp, 512);
    if(substr($lastmessage, 0, 3) != 250) {
    exit("END - ".$lastmessage);
    }
    
    fputs($fp, "QUIT\r\n");
    }

测试代码：

    <?php 
    require "sendmail.php";
    sendmail("tomail@163.com","消息","测试一下");

注意事项

1. 拼写是smtp不是stmp,刚开始还找半天smtplib的库，其实是自带的。
2. 文件保存的时候文件名不要写成email，这和库Email重了。
