[英]How to send response to user before sending mail in php
我正在開發一個項目,有兩個過程。
我需要做所有這一切,但是要花很多時間。 所以現在我正在考慮使用多線程。 任何人都可以幫助如何在php中實現嗎?
我只需要盡快發送回復。 這是我的代碼,我創建了一個發送郵件的功能,並且在成功發送完完整的郵件后,我使用JSON編碼向用戶發送響應。
/ 郵件功能 /
public function emailSent($booking_id, $mailHeading, $smallHeading, $subject, $smallHeadingcustomer ,$status, $senttoestimator = true, $senttocustomer = true, $mailSent = false){
if(!empty($booking_id)){
$bookingData = $this->Cnc_model->getData('bookings', array('*'), array('id'=>$booking_id));
if(!empty($bookingData)){
if(!empty($bookingData[0]['estimator_id']) && $bookingData[0]['estimator_id'] != 0){
$name = $this->Cnc_model->getData('users',array('username', 'email'), array('user_id'=> $bookingData[0]['estimator_id']));
$estimator_name = $name[0]['username'];
$estimator_mail = $name[0]['email'];
}
if($bookingData[0]['customer_id'] != 0){
$cname = $this->Cnc_model->getData('customers',array('name', 'office_contact_email'), array('id'=> $bookingData[0]['customer_id']));
$customer_name = $cname[0]['name'];
$customer_mail = $cname[0]['office_contact_email'];

這取決於您想走多深。 理想的方法是運行RabbitMQ或Gearman服務器並設置一個“發送郵件”作業供它們處理。 提交作業非常快,並且可以使腳本完成並將響應發送回用戶,但是當然這將涉及設置更多的基礎結構,編寫/維護更多的代碼以處理該作業以及處理重試/錯誤狀態。
問題最少的方法可能是運行將中繼郵件的本地郵件服務器。 移交應該非常快,可以提供更好的“有效”響應(至少用戶會知道郵件已移交給本地郵件服務器)並允許腳本繼續進行。 如果電子郵件失敗,則由本地郵件服務器作為對管理員或“發件人”用戶的退回處理。
概述一種方式在這里將意味着第一個發送響應,則處理的電子郵件-這意味着它不可能報告故障給用戶。 不太理想,但這取決於您的情況-也許管理員可以處理失敗的消息並可以重新發送?
您可以使用ignore_user_abort(true); 設置客戶端斷開連接是否應導致腳本中止。 這將斷開您當前的連接,然后將響應發送到前端,但仍執行其余代碼。
ignore_user_abort(true);
ob_start();
echo "success";
$serverProtocole = filter_input(INPUT_SERVER, 'SERVER_PROTOCOL', FILTER_SANITIZE_STRING);
header($serverProtocole.' 200 OK');
header('Content-Encoding: none');
header('Content-Length: '.ob_get_length());
header('Connection: close');
ob_end_flush();
ob_flush();
flush();
最初對API使用后端驗證,然后使用上述代碼發送響應,然后您可以編寫代碼向用戶發送電子郵件,這樣前端將獲得響應,腳本將執行直到遇到返回或死亡為止。 這種方法的問題在於,如果在發送電子郵件時出錯,則無法向前端發送響應。
否則,您可以在代碼中使用郵件隊列來稍后執行任務
