环境:
- Laravel 5.3
案例:
有关“事件”的邮件,包括带有 iCalendar 文件 (.ics
) 的附件。正在使用 PHP
生成 ics
文件。
问题:
使用 ics
文件发送邮件时,Laravel 返回以下错误:
Swift_IoException in FileByteStream.php line 144: Unable to open file for reading [/storage/app/public/events/eventname.ics]
生成的文件在没有邮件的情况下使用时看起来很好。该事件将添加到日历中,因此文件不会损坏。调试时(路径上的dd
)文件被返回,因此文件夹/访问权限似乎也很好。
代码:
// Build mail
public function build()
{
$event = $this->createEvent($this->data[2]->planned_at, $this->data[2]->subject, $this->data[2]->content);
return $this->view('emails.template')
->from('info@stackoverflow.nl', 'Stackoverflow')->subject($this->data[2]->subject)
->with([
'token' => $this->data[0],
'email' => $this->data[1],
'mail' => $this->data[2],
'sponsors' => $this->data[3],
'name' => $this->data[4],
])
->attach(Storage::url('app/public/events/' . $this->data[2]->subject . '.ics'), [
'as' => $this->data[2]->subject . '.ics',
'mime' => 'calendar/event',
]);
}
// Build ics file
static function createEvent($date, $subject, $content)
{
$dateTimeArr = explode(' ', $date);
$newDate = $dateTimeArr[0];
$dateArr = explode('-', $newDate);
$newDate = $dateArr[0] . $dateArr[1] . $dateArr[2] . '-' . $dateTimeArr[1];
$date = substr($newDate, 0, -9);
$startTime = str_replace(":", "", substr($newDate, 9, -3));
$strip = str_replace("\r", "", strip_tags($content));
$desc = str_replace("\n", "", $strip);
// ICS
$mail[0] = "BEGIN:VCALENDAR";
$mail[1] = "-//WEBSITE v1.0//NL";
$mail[2] = "VERSION:2.0";
$mail[3] = "METHOD:PUBLISH";
$mail[4] = "BEGIN:VCALENDAR";
$mail[5] = "DTSTART:" . $date . "T" . $startTime . "00Z";
$mail[6] = "DTEND:" . $date . "T" . $startTime . "00Z";
$mail[7] = "DTSTAMP:" . gmdate('Ymd') . 'T' . gmdate('His') . "Z";
$mail[8] = "UID:" . md5(uniqid(mt_rand(), true));
$mail[9] = "ORGANIZER;" . "Stackoverflow";
$mail[10] = "CREATED:" . $date . "T" . $startTime . "00Z";
$mail[11] = "DESCRIPTION:" . $desc;
$mail[12] = "LAST-MODIFIED:" . $date . "T" . $startTime . "00Z";
$mail[13] = "LOCATION:" . "";
$mail[14] = "SEQUENCE:0";
$mail[15] = "STATUS:CONFIRMED";
$mail[16] = "SUMMARY:" . "";
$mail[17] = "TRANSP:OPAQUE";
$mail[18] = "END:VEVENT";
$mail[19] = "END:VCALENDAR";
//set correct content-type-header
$filename = $subject . '.ics';
$mail = implode("\r\n", $mail);
header("text/calendar");
Storage::put('public/events/' . $filename , $mail);
}
最佳答案
许多类似的票证建议您需要将真实路径传递给 swiftmailer。
类似这样的事情:
public function build()
{
$event = $this->createEvent($this->data[2]->planned_at, $this->data[2]->subject, $this->data[2]->content);
$path=realpath('app/public/events/' . $this->data[2]->subject . '.ics');
return $this->view('emails.template')
->from('info@stackoverflow.nl', 'Stackoverflow')->subject($this->data[2]->subject)
->with([
'token' => $this->data[0],
'email' => $this->data[1],
'mail' => $this->data[2],
'sponsors' => $this->data[3],
'name' => $this->data[4],
])
->attach($path), [
'as' => $this->data[2]->subject . '.ics',
'mime' => 'calendar/event',
]);
}
