如何從Amazon API解析stdClass響應返回字符串

Question

您好，我想使用從Amazon api收集的數據設置magento產品的描述。我調用API，並在日誌中我得到不過接收響應：

Recoverable Error: Object of class stdClass could not be converted to string

的問題是如何解析的信息轉換成字符串，因此可以在Magento的產品的詳細信息可以使用？

<?php 
require_once '../abstract.php'; 
require('AmazonApi.php'); 

class Mage_Shell_Amazon extends Mage_Shell_Abstract 
{ 


public function run() { 

    //Create API access object 
    $public_key = '*********'; 
    $secret_key = '*********+*******'; 
    $associate_tag = '*******-21'; 
    $amazon_api = new AmazonAPI($public_key, $secret_key, $associate_tag); 


    //load product by categoryId 
    $products = Mage::getModel('catalog/product') 
     ->getCollection() 
     ->addAttributeToSelect('asin') 
     ->addAttributeToSelect('description'); 

    //Array of request parameters 
    foreach($products as $prod) 
    { 
     //load the actual products data 
     $product = Mage::getModel('catalog/product')->load($prod->getId()); 

     $asin = $product->getAsin(); 

     $params_array = array(
      'Operation' => 'ItemLookup', 
      'IdType' => 'ASIN', 
      'ItemId' => $asin , 
      'ResponseGroup' => 'Tracks'); 

     // returns a list of items for the search query 'Slow Magic' 
     $response = $amazon_api->sendRequest($params_array); 

     $product->setDescription($restponse); 
     $product->getResource()->saveAttribute($product, 'description'); 

     foreach ($response as $restponse) 
     { 
      sleep(1); 
     } 
     echo '<pre>'; 
     print_r($restponse); 
     echo '</pre>'; 

    } 

    //  foreach($parsed_xml->OperationRequest->Errors->Error as $error){ 
    //   echo "Error code: " . $error->Code . "\r\n"; 
    //   echo $error->Message . "\r\n"; 
    //   echo "\r\n"; 
    //  } 
     } 
    } 

     $amazonConnector = new Mage_Shell_Amazon(); 
     $amazonConnector->run();

我不知道在與亞馬遜API的細節，所以我會做的第一件事就是將研究在亞馬遜如何文檔得到一個字符串描述。

如果不是，看結果，說明是結構化數據。例如，在這種情況下，它是一個軌道列表和一個ID。如果你需要得到你可以先轉換成stdClass的描述到一個數組使用：

json_decode(json_encode($item), true); 

，然後一旦這是一個數組，你可以通過它走遞歸和編譯字符串。如果它是一維數組，則可以簡單地使用帶有分隔符的implode將它連接在一起，但在這種情況下，它是一個多維數組。

但是，我應該再次重申，這應該是LAST度假村。首先儘可能努力地找到顯示亞馬遜描述的最佳實踐。
