如何从prestashop web服务获取json格式的数据

我需要为客户端请求返回json格式的数据。我使用了prestashop 1.6并启用了Web服务并创建了authkey。我使用下面的代码如何从prestashop web服务获取json格式的数据

<?php 
define('DEBUG', true);           // Debug mode 
define('PS_SHOP_PATH', 'http://www.example.com');  // Root path of your PrestaShop store 
define('PS_WS_AUTH_KEY', 'myauthkey'); // Auth key (Get it in your Back Office) 
require_once('PSWebServiceLibrary.php'); 

try 
{ 
    $webService = new PrestaShopWebservice(PS_SHOP_PATH, PS_WS_AUTH_KEY, DEBUG); 

    // Here we set the option array for the Webservice : we want customers resources 
    $opt['resource'] = 'categories'; 

    $opt['output_format'] = 'JSON'; 

    $opt['ps_method'] = 'GET'; 

    // Call 
    $output = $webService->get($opt); 
    echo $output; 
} 
catch (PrestaShopWebserviceException $e) 
{ 
    // Here we are dealing with errors 
    $trace = $e->getTrace(); 
    if ($trace[0]['args'][0] == 404) echo 'Bad ID'; 
    else if ($trace[0]['args'][0] == 401) echo 'Bad auth key'; 
    else echo 'Other error'; 
} 
?>

但它返回像

如何在不HTTP响应头并返回HTTP BODY只返回JSON输出。

看来你得到了一个simpleXMLElement。可以通过使用json_encode()转换成JSON也看这个问题：PHP convert XML to JSON

我已经使用json_encode（$ array）检查它是否返回json格式的数据，但是我只需要响应json字符串，但是它会返回http resonse header和RETURN HTTP BODY文本。如何删除这些东西，并只响应json字符串 –

你可以尝试去掉所有的东西，返回HTTP身体与strstr（http://php.net/manual/en/function.strstr.php），然后把它槽json_encode我猜这里是一个例子，只是做这个：http://stackoverflow.com/questions/7802821/php-remove-all-characters-before-specific-string –

如果我不回应任何东西，它默认显示HTTP RESPONSE HEADER和RETURN HTTP BODY详细信息。为什么prestashop webservice模块回显http内容 –

我解决了这个问题

public function printDebug($title, $content) 
    { 
     //echo '<div style="display:table;background:#CCC;font-size:8pt;padding:7px"><h6 style="font-size:9pt;margin:0">'.$title.'</h6><pre>'.htmlentities($content).'</pre></div>'; 
    }
