站点迁移后如何解决 Magento 商店与 POS 系统的集成问题?

How to fix integration issue Magento store with POS system after site migration?

我们将 Magento 站点 (Magento 1.8.1.0) 从旧服务器迁移到新服务器。

但是,我们不能再使用 Winepos 集成扩展了。

我们的站点与 Winepos system 连接,并且此 Magento 扩展程序在迁移工作之前已经运行。

这是Winepos API manual

此时,我们认为一些 PHP 模块没有安装在我们的新服务器上。

但是,我们不知道哪些 PHP 模块没有安装。似乎所有 PHP 个模块都安装在我们的新服务器上。

与Winepos整合的Magento扩展如下。此扩展由两个文件组成。

Config.xml

<config>
 <global>
   <events>
     <checkout_onepage_controller_success_action>
       <observers>
         <igor_winepos_order_success_observer>
           <type>singleton</type>
           <class>igor_Winepos_Model_Wineposobserver</class>
           <method>checkoutSuccessObserve</method>
         </igor_winepos_order_success_observer>
       </observers>
     </checkout_onepage_controller_success_action>
    </events>
   </global>
  </config>

wineposobserver.php

class igor_Winepos_Model_Wineposobserver extends Varien_Event_Observer {

  function customlog($obj) {
    ob_start();
    var_dump($obj);
    $out1 = ob_get_contents();
    ob_end_clean();
    $f = fopen('/tmp/log.txt', 'ab');
    fwrite($f, $out1);
    fclose($f);
  }

  public function __construct() {
  }

  public function checkoutSuccessObserve($observer) {
    // $event = $observer->getEvent();
    $order_ids = $observer->getData('order_ids');
    if(gettype($order_ids) == 'array' && count($order_ids) == 1) {
       $the_order = Mage::getModel('sales/order')->load($order_ids[0]);
       Mage::helper('globalfunc')->registerOrderWithWinePOSAsynchronousWithTimeout($the_order);
    }
 }
}

我在 Apache 日志中得到以下信息:

PHP Warning: PHP Startup: apc.shm_segments setting ignored in MMAP mode in Unknown on line 0 [Sun Apr 30 06:32:30 2017] [notice] Apache/2.2.22 (Ubuntu) mod_ssl/2.2.22 OpenSSL/1.0.1 configured -- resuming normal operations

 285:   function registerOrderWithWinePOSAsynchronousWithTimeout($the_order) {
 286      try {
 287        $items = $the_order->getAllItems();
 ...
 426          $ordered_raw_item = $ordered_products_raw_items[$ordered_product_id];
 428:         $product_winepos_id = trim(strval($product->getResource()->getAttribute('winepos_id')->getFrontend()->getValue($product)));
 429  
 430          $item_element = $doc->createElement('item');
 432          $item_num_element = $doc->createElement('item-num');
 433:         $item_num_element->appendChild($doc->createTextNode(strval($product_winepos_id)));
 434          $item_element->appendChild($item_num_element);
 ...
 466        $the_xml = $doc->saveXML();
 468:       // $post_result = Mage::helper('globalfunc')->post_to_api_winepos('https://wines-in-november.vznlink.com/orders', $the_xml, 'admin276975', '8dc670fb943dc2c0a1415405cdf00e3ec579c4e6', 8, 10);
 470:       return Mage::helper('globalfunc')->delayed_post_to_winepos($the_xml);
 471      } catch(Exception $e) {
 472        $this->customlog($e);
 ...
 475    }

我创建了一个与 POS 系统集成的新模块,并成功实现了库存同步。 这项工作应该由 cron 作业来完成。为此,我创建了三个单独的脚本文件。 此外,POS 提供商应在每个时间间隔通过 ftp 以 txt 文件形式提供订购的产品信息,包括库存信息。

lftp -u [username],[password] -e'set ftp:passive-mode false; cd files; put data.txt; quit' [folder name]

cron job操作块如下

cron_file_mover.php

  $start = microtime(true);
  shell_exec('cp /home/files/data.txt /var/www/vhosts/magento/');
  shell_exec('chown -R www-data:www-data /var/www/vhosts/magento/');
  $end = microtime(true);
  echo 'Run time: '.round($end-$start, 4).'s';

cron_pos_post_script.php

Utils::initMagento(); $MAX_RETRIES = 5;
$delayed_jobs = Utils::mageGetRows("select * from delayed_jobs where job_type = 'pos_order' and status = 'todo' order by created_at DESC");
$current_index = 0;
foreach($delayed_jobs as $delayed_job) {
  $current_index += 1;
  $retry_count = intval($delayed_job['retry_count']);
  $retry_count += 1;
  $post_result = Mage::helper('globalfunc')->post_to_api_pos('https://vznlink.com/orders', $delayed_job['job_details'], 'admin', 'fd93d2de58ab', 8, 10);  
   Utils::mageSqlExecute("update delayed_jobs set status = 'done' where id = " . $delayed_job['id']);

Utils::mageSqlExecute("update delayed_jobs set status = '" . $new_status . "', retry_count = " . $retry_count . " where id = " . $delayed_job['id']);
}

cron_pos_update_script.php

$PATH_TO_FILE = '/var/www/vhosts/magento/data.txt';

function read_pos_file($path_to_file) {
  $min_count_required_for_product = 12;
  $f = fopen($path_to_file, 'rb');
  $text = trim(fread($f, 100000000));
  fclose($f);
  $lines = preg_split('/\r\n|\r|\n/i', $text);
  $products = array();
  foreach($lines as $line) {
  $product = preg_split('/\t/i', trim($line));
  if(count($product) >= $min_count_required_for_product) {
      $product[0] = strval(trim($product[0]));
      $product[1] = strval(trim($product[1]));
      $product[2] = strval(trim($product[2]));
      $product[11] = intval(strval(trim($product[11])));
      $products []= $product;
  }
}
  return $products;
}

function update_stock_for_stock_item($product_id, $new_stock) {
   $stock_item = Mage::getModel('cataloginventory/stock_item')->loadByProduct($product_id);
   $stock_item->setData('qty', $new_stock);
   if($new_stock > 0) {
      $stock_item->setData('is_in_stock', 1);
   }
   $stock_item->save();
}
   $products = read_pos_file($PATH_TO_FILE);
   $total_count = 0; $processed_count = 0;
   foreach($products as $product) {
     $total_count += 1;
     $item_number = $product[0];
     $new_stock = $product[11];
     if($new_stock < 0) {
        $new_stock = 0;
     }
   $products_matching_item_number = Mage::getModel('catalog/product')->getCollection()->addAttributeToSelect('pos_id')->addFieldToFilter('pos_id', $item_number)->getItems();
   if(count($products_matching_item_number) == 1) {
      $products_matching_item_number = array_values($products_matching_item_number);
      $matching_product = $products_matching_item_number[0];
      $matching_product_id = $matching_product->getId();
      update_stock_for_stock_item($matching_product_id, $new_stock);
      $processed_count += 1;
   }
}

cron作业设置如下。

10 * * * * /usr/bin/php /var/www/vhosts/magento/pos/cron_winepos_post_script.php &> /dev/null
10 * * * * /usr/bin/php /var/www/vhosts/magento/pos/cron_winepos_update_script.php &> /dev/null
20 * * * * /usr/bin/php /var/www/vhosts/magento/pos/cron_pos_file_mover.php &> /dev/null

记住,检查 POS 系统提供的 POS 数据,cron 作业设置,检查更新脚本操作。
