【问题描述】：

我通过 web 服务创建了一个简单的添加产品到 prestashop，但是当我尝试将它添加到数据库时，我只看到一个错误 'Bad parameters given'。我的代码有什么问题？以及如何通过 webservice 找到一个类别是否已经存在？

  $reader = new XMLReader;
$reader->open($filename); // open an large xml with products and it should add this to db prestashop via webservice
$xml = $webService->get(array('url' => $shopUrl.'/api/products?schema=blank'));
$resources = $xml->children()->children();
foreach ($resources as $resource) {
  while ($reader->read()) {
    if($reader->nodeType == XMLReader::ELEMENT) { 
      $name = $reader->name;
    }

    if($reader->nodeType == XMLReader::TEXT || $reader->nodeType == XMLReader::CDATA){
        switch ($name) {
          case 'id':
           if ($reader->value != '0')
              $resource->id = $reader->value;
            break;

          case 'ilosc':
            $resource->quantity = $reader->value;
            break;

          case 'cena_netto':
            $resource->price = $reader->value;
            break;

          case 'opis':
            $resource->description = $reader->value;
            break;

          case 'waga':
            $resource->weight = $reader->value;
            break;

          case 'kod_kreskowy':
            $resource->ean13 = $reader->value;
            break;
        }
    }

    if($reader->nodeType == XMLReader::END_ELEMENT && $reader->name == 'produkt'){
      $reader->next();
      $opt['postXml'] = $xml->asXML();
      $xml = $webService->add($opt);
    }
  }
}

【解决方案1】：

您可以从categories?schema=blank 获取类别，它会返回给您

<?xml version="1.0" encoding="UTF-8"?>
<prestashop xmlns:xlink="http://www.w3.org/1999/xlink">
<categories>
<category id="1" xlink:href="http://www.yourshop/api/categories/1"/>
<category id="2" xlink:href="http://www.yourshop/api/categories/2"/>
<category id="3" xlink:href="http://www.yourshop/api/categories/3"/>
</categories>
</prestashop>

每个xlink 都会回复你：

<?xml version="1.0" encoding="UTF-8"?>
<prestashop xmlns:xlink="http://www.w3.org/1999/xlink">
