yii2.0 发送邮件带word小附件

   
把 common/config/main-local.php 下的 mailer 注释掉：

          'mailer'=>[

                   'class'=>'yii\swiftmailer\Mailer',

                   'viewPath'=>'@common/mail',

                   'useFileTransport'=>false,

                   'transport'=>[

                                    'class'=>'Swift_SmtpTransport',

                                    'host'=>'',                                              //自己申请邮箱时的服务器

                                    'username'=>'',                                     //申请时的账号

                                    'password'=>'',                                     //申请时的密码

                                    'port'=>'25',                                           //端口

                                    'encryption'=>'tls'                                  //一种加密方式，报错时删除它再试试（我这里就不支持这种加密方式）

                    ],

                   'messageConfig'=>[

                                    'charset'=>'UTF-8',                                                          //设置字符集

                                    'from'=>['？？？'=>？？？]                   //给发送的邮箱起个别名

                    ]

          ]

   

    在任意控制下创建一个方法：

          $file_size=filesize(路径);

            $fp=fopen(路径,'r');               //只读模式打开

            $buff=1024;

            $file_count=0;

            $file_con='';

            while(!feof($fp)&&file_count<$file_size){

                  $file_con.=fread($fp,$buff);                                             //因为文件每读取一次只要不关闭或重置，指针就会停在上次最后读取的位置。下次继续读取。所以长度不必改变。

                  $file_count+=$buff;

            }

            fclose($fp);

            $mail=\Yii::$app->mailer->compose();

            $mail->attachContent($file_con,['filename'=>'demo.docx','contentType'=>'application/octet-stream']);

                                               
//附件内容            //附件名称                 //文件类型

            $mail->setTo(收件人账号);

            $mail->setSubject("标题");
            $mail->setHtmlBody("内容");

            $mail->send();                                                                   
//发送

            unset($file_con);                                                                 //销毁附件内容字符串
