我有一个执行以下步骤的脚本
- 用户登录,添加 SMS 消息并指定收件人。该信息被添加到“排队消息表”;
- 某些进程使用 API 发送消息并将消息移动到“已发送消息表”;
- 发送报告出现,消息从“已发送消息表”中删除,引用已发送消息的日志条目被添加到“已发送消息日志表”中。
当大量消息在“队列消息表”中排队时,步骤(2)和(3)耗时较长,
在将消息推送到 API 之前,会为每个接收者生成一个随机的唯一 ID,以供以后检索报告时参考,该 ID 用于表“已发送消息日志表”。
下面是示例脚本
<?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();

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;
}
