PHP调用Python快速发送高并发邮件

1 简介

       在PHP中发送邮件，通常都是封装一个php的smtp邮件类来发送邮件。但是PHP底层的socket编程相对于python来说效率是非常低的。CleverCode同时写过用python写的爬虫抓取网页，和用php写的爬虫抓取网页。发现虽然用了php的curl抓取网页，但是涉及到超时，多线程同时抓取等等。不得不说python在网络编程的效率要比PHP好的多。

     PHP在发送邮件时候，自己写的smtp类，发送的效率和速度都比较低。特别是并发发送大量带有附件报表的邮件的时候。php的效率很低。建议可以使用php调用python的方式来发送邮件。

2 程序

2.1 python程序

      php的程序和python的文件必须是相同的编码。如都是gbk编号，或者同时utf-8编码，否则容易出现乱码。python发送邮件主要使用了email模块。这里python文件和php文件都是gbk编码，发送的邮件标题内容与正文内容也是gbk编码。

2.2 python程序使用帮助

输入以下命令，可以输出这个程序的使用帮助

# python mail.py --help

2.3 php程序

这个程序主要是php拼接命令字符串，调用python程序。注意：用程序发送邮件，需要到邮件服务商，开通stmp服务功能。如qq就需要开通smtp功能后，才能用程序发送邮件。开通如下图。

php调用程序如下：

<?php/** * SendMail.php *  * 发送邮件类 * * Copyright (c) 2015 by http://blog.csdn.net/CleverCode * * modification history: * -------------------- * 2015/5/18, by CleverCode, Create * */class SendMail{    /**     * 发送邮件方法     *     * @param string $fromAddress 发件人,'[e-mail]' 或者修改发件人名 'CleverCode<[e-mail]>'     * @param string $toAddress 收件人,多个收件人逗号分隔,'[e-mail],[e-mail],[e-mail]....'， 或者 'test1<[e-mail]>,test2<[e-mail]>,....'     * @param string $subject 标题     * @param string $content 正文     * @param string $fileList 附件，附件必须是绝对路径,多个附件逗号分隔。'/data/test1.txt,/data/test2.tar.gz,...'     * @return string 成功返回'OK'，失败返回错误信息     */    public static function send($fromAddress, $toAddress, $subject = NULL, $content = NULL, $fileList = NULL){        if (strlen($fromAddress) < 1 || strlen($toAddress) < 1) {            return '$fromAddress or $toAddress can not be empty!';        }        // smtp服务器        $smtpServer = 'smtp.qq.com';        // 登录用户        $username = '[e-mail]';        // 登录密码        $password = '123456';                // 拼接命令字符串，实际是调用了/home/CleverCode/mail.py        $cmd = "LANG=C && /usr/bin/python /home/CleverCode/mail.py";        $cmd .= " -s '$smtpServer'";        $cmd .= " -u '$username'";        $cmd .= " -p '$password'";                $cmd .= " -f '$fromAddress'";        $cmd .= " -t '$toAddress'";                if (isset($subject) && $subject != NULL) {            $cmd .= " -S '$subject'";        }                if (isset($content) && $content != NULL) {            $cmd .= " -c '$content'";        }                if (isset($fileList) && $fileList != NULL) {            $cmd .= " -F '$fileList'";        }                // 执行命令        exec($cmd, $out, $status);        if ($status == 0) {            return 'OK';        } else {            return "Error,Send Mail,$fromAddress,$toAddress,$subject,$content,$fileList ";        }        return 'OK';    }}

2.3 使用样例

压缩excel成附件，发送邮件。

<?php/** * test.php * * 压缩excel成附件，发送邮件 * * Copyright (c) 2015 http://blog.csdn.net/CleverCode * * modification history: * -------------------- * 2015/5/14, by CleverCode, Create * */include_once ('SendMail.php');/* * 客户端类 * 让客户端和业务逻辑尽可能的分离，降低页面逻辑和业务逻辑算法的耦合， * 使业务逻辑的算法更具有可移植性 */class Client{    public function main(){                // 发送者        $fromAddress = 'CleverCode<[e-mail]>';                // 接收者        $toAddress = '[e-mail]';                // 标题        $subject = '这里是标题！';                // 正文        $content = "您好：\r\n";        $content .= "   这里是正文\r\n ";                // excel路径        $filePath = dirname(__FILE__) . '/excel';        $sdate = date('Y-m-d');        $PreName = 'CleverCode_' . $sdate;                // 文件名        $fileName = $filePath . '/' . $PreName . '.xls';                // 压缩excel文件        $cmd = "cd $filePath && zip $PreName.zip $PreName.xls";        exec($cmd, $out, $status);        $fileList = $filePath . '/' . $PreName . '.zip';                // 发送邮件（附件为压缩后的文件）        $ret = SendMail::send($fromAddress, $toAddress, $subject, $content, $fileList);        if ($ret != 'OK') {            return $ret;        }                return 'OK';    }}/** * 程序入口 */function start(){    $client = new Client();    $client->main();}start();?>
