的某些部分我有執行下列步驟瓶頸放慢我的劇本
- 用戶登錄腳本中,增加了一個短信,並指定收件人。該信息被添加到「排隊的消息表」中;
- 某些進程使用API發送消息並將消息移至「已發送消息表」;
- 發送傳送報告並從「已發送消息表」中刪除消息,並將引用已發送消息的日誌條目添加到「已發送消息日誌表」中。
當消息量大被排隊在「隊列消息表」,步驟(2)和(3)需要很長的時間,
消息之前被推到API,隨機爲每個收件人生成唯一的ID,以供稍後在檢索報告時參考,該ID用於「發送消息日誌表」表。
下面是示例腳本
<?php
class Message {
/*
* random unique id for mobile number
*/
protected $mobile_ids = array();
public function add_unique_id($id, $mobile)
{
$this->mobile_ids[] = array($id, $mobile);
}
public function get_unique_id()
{
return $this->mobile_ids;
}
// The method that generated the xml for API
public function makeXML($param,$multi_part=false)
{
$xmlString =
"<SMS>
<authentification>
<username>sss</username>
<password>sss</password>
</authentification>
<message>
<sender>sender</sender>";
if($multi_part == "longSMS") $xmlString .= "<type>longSMS</type>";
$xmlString .= "<text>{$param['text']}</text></message><recipients>";
// Array of mobile numbers came from $param
$phone_numbers = $param['numbers'];
// Loop through the array and generate <gsm messageId='0001'>mobile</gsm>
foreach($phone_numbers as $mobile) {
// Generate id for mobile
$msg_id = $this->make_random_int();
/**
* This is the slow part of the script,
* IDs are added to the array for logging into the database
* When message is sent, i looped through the id and created a log for this message
**/
$this->add_unique_id($msg_id, $mobile);
$xmlString .= "<gsm messageId=\"{$msg_id}\">{$mobile}</gsm>";
}
$xmlString .= "</recipients></SMS>";
return $xmlString;
}
/**
* This is the method that created the log
* Log the sms
* You will need to call $msgid = $this->update_db('the sms')
* return value of $msgid is last_insert_id
*/
public function log_sms($msgid) {
// Log the currently sent message
$userData = array();
$now = date('Y-m-d H:i:s');
foreach ($this->mobile_ids as $data) {
$userData[] = "('{$msgid}', '{$data[0]}', '{$data[1]}', 'QUEUED', '0000-00-00', '0000-00-00', '{$now}')";
}
$query = 'INSERT INTO sent_sms_log (txtId,msgID,mobile,status,sentdate_time,deliver_date_time,sysdate_time) VALUES' . implode(',', $userData);
$this->ci->db->query($query);
$this->mobile_ids = array(); // reset the array
}
// Make random int
protected function make_random_int() {
$this->ci->load->helper('string');
$int = random_string('numeric', 12);
return $int;
}
/**
* Update database after sms sent
* @return int
*/
public function update_db($msg, $owner, $qid=0) {
$data = array('qid'=> $qid, 'sms' => $msg, 'date_time' => date('Y-m-d H:i:s'), 'owner' => $owner);
$this->ci->db->insert('f_sent_sms', $data);
return $this->ci->db->insert_id();
}
}
將消息傳遞給API是可以的,通過ID循環並將其記錄到數據庫中是很慢的部分,我想知道是否可以找到更好的方法來生成並記錄ID – elf1984 2011-04-18 23:21:00
