Swift_IoException 无法打开文件读取 yii2

Question

我正在用 Yii2 开发 Web 应用程序。我在发送电子邮件时附加了一个文件。但是在电子邮件中附加文件后我遇到了这个错误。

我发送带附件的电子邮件的代码是这样的

Yii::$app->mailer->compose()
                ->setFrom('sender email')
                ->setTo('reciever email')
                ->setSubject('test')
                ->setHtmlBody('test')
                ->attach('path of attachment file')
                ->send();

我真的遇到了一个大问题，请帮忙。

根据此 link http://www.yiiframework.com/doc-2.0/guide-tutorial-mailing.html#file-attachment ，attach() 方法需要文件名（字符串）作为参数。要修复您的代码：

$model->attachment = UploadedFile::getInstances($model, 'attachment');

if($model->attachment) {
    $message = Yii::$app->mailer->compose()
    ->setFrom([ Yii::$app->user->identity->email => 'Sample Mail'])
    ->setTo($model->email)
    ->setSubject($model->subject)
    ->setHtmlBody($model->content);

    foreach ($model->attachment as $file) {
        $filename = 'emailattachments/' .$file->baseName. '.' . $file->extension; # i'd suggest adding an absolute path here, not a relative.
        $file->saveAs($filename);
        $message->attach($filename);
    }

    $message->send();
}
