问题 eBay API下载用户列表（eBay API用户指南/分步指南）

我是eBay API的新手，目前正在使用PHP开发，我已设法使用GetItem将基于Item ID的订单详细信息导入到我网站的数据库中。但我现在要做的是将用户帐户链接到我的网站并将其列表导入我的数据库。我已经把我用于GetItem的代码（下面），但现在我卡住了，我不知道要使用什么，GetAccount，GetUser或GetSellerList：

第一： 让我的用户从我的网站重定向到eBay，以授权我的应用程序访问他/她的列表。

第二： 将该列表（现在回声已足够）导入我的网站。

这是我的GetItem代码：

     require_once('keys.php');
     require_once('eBaySession.php');

    if(isset($_POST['Id']))
    {
        //Get the ItemID inputted
        $id = $_POST['Id'];


        //SiteID must also be set in the Request's XML
        //SiteID = 0  (US) - UK = 3, Canada = 2, Australia = 15, ....
        //SiteID Indicates the eBay site to associate the call with
        $siteID = 101;
        //the call being made:
        $verb = 'GetItem';

        ///Build the request Xml string
        $requestXmlBody = '<?xml version="1.0" encoding="utf-8" ?>';
        $requestXmlBody .= '<GetItemRequest xmlns="urn:ebay:apis:eBLBaseComponents">';
        $requestXmlBody .= "<RequesterCredentials><eBayAuthToken>$userToken</eBayAuthToken></RequesterCredentials>";;
        $requestXmlBody .= "<ItemID>$id</ItemID>";
        $requestXmlBody .= '</GetItemRequest>';

        //Create a new eBay session with all details pulled in from included keys.php
        $session = new eBaySession($userToken, $devID, $appID, $certID, $serverUrl, $compatabilityLevel, $siteID, $verb);

        //send the request and get response
        $responseXml = $session->sendHttpRequest($requestXmlBody);
        if(stristr($responseXml, 'HTTP 404') || $responseXml == '')
            die('<P>Error sending request');

        //Xml string is parsed and creates a DOM Document object
        $responseDoc = new DomDocument();
        $responseDoc->loadXML($responseXml);


        //get any error nodes
        $errors = $responseDoc->getElementsByTagName('Errors');

        //if there are error nodes
        if($errors->length > 0)
        {
            echo '<P><B>eBay returned the following error(s):</B>';
            //display each error
            //Get error code, ShortMesaage and LongMessage
            $code = $errors->item(0)->getElementsByTagName('ErrorCode');
            $shortMsg = $errors->item(0)->getElementsByTagName('ShortMessage');
            $longMsg = $errors->item(0)->getElementsByTagName('LongMessage');
            //Display code and shortmessage
            echo '<P>', $code->item(0)->nodeValue, ' : ', str_replace(">", "&gt;", str_replace("<", "&lt;", $shortMsg->item(0)->nodeValue));
            //if there is a long message (ie ErrorLevel=1), display it
            if(count($longMsg) > 0)
                echo '<BR>', str_replace(">", "&gt;", str_replace("<", "&lt;", $longMsg->item(0)->nodeValue));

        }

        else //no errors
        {
            //get the nodes needed
            $titleNode = $responseDoc->getElementsByTagName('Title');
