如何修复请求缺少必需的输入标签

Question

我正在尝试从用户的ebay帐户中获取一些产品，但是当我运行代码时，我只收到一个错误"您的应用程序遇到错误。此请求缺少必需的输入标记"或"."

<?php
function print_d($array){    echo "<pre>n";    print_r($array);    echo "</pre>n";}
$mytoken = "************mytoken************";
$devId   = "************mydevId************";
$appId   = "************myappId************";
$certId  = "************mycertId************";
$wsdl_url = 'http://developer.ebay.com/webservices/latest/ebaySvc.wsdl';
$apiCall = "GetSellerList";
$credentials = array('AppId' => $appId, 'DevID' => $devId, 'AuthCert' => $certId);
$client = new SOAPClient($wsdl_url, array('trace' => 1, 'exceptions' => 0, 'location' => "https://api.ebay.com/wsapi?callname=$apiCall&appid=$appId&siteid=0&version=803&Routing=new"));
$eBayAuth = array('eBayAuthToken' => new SoapVar($mytoken, XSD_STRING, NULL, NULL, NULL, 'urn:ebay:apis:eBLBaseComponents'),
'Credentials' => new SoapVar ($credentials, SOAP_ENC_OBJECT, NULL, NULL, NULL, 'urn:ebay:apis:eBLBaseComponents'));  
$header_body = new SoapVar($eBayAuth, SOAP_ENC_OBJECT);    
$header = array(new SOAPHeader('urn:ebay:apis:eBLBaseComponents', 'RequesterCredentials', $header_body));                
//set the API call parameters
$params = array('UserID'=>'**sellerid**','DetailLevel'=>'ReturnAll','WarningLevel'=>'High','IncludeWatchCount'=>'true','Pagination'=>array('EntriesPerPage'=>'20','PageNumber'=>'1'),'Version' => '803', 'CreateTimeFrom'=>'2019-07-01T01:01:02.768Z', 'CreateTimeTo'=>'2019-08-22T01:01:02.768Z');  
$request = $client->__soapCall($apiCall, array($params), NULL, $header);  //make the actual API call
print_d($request);
?>

这就是我得到的：

stdClass Object
(
[Timestamp] => 2019-08-23T05:54:30.954Z
[Ack] => Failure
[Errors] => stdClass Object
(
[ShortMessage] => Your application encountered an error.

Answer 2

我在德语中Your application encountered an error. This request is missing required input tag ""或In der Anwendung ist ein Fehler aufgetreten. In dieser Anforderung fehlt der erforderliche Eingabetag ""遇到了相同的错误。

首先，如果您在浏览器中发出请求(99%确定(，则必须查看浏览器源代码HTML代码(CTRL + U(，将显示隐藏在"漂亮"浏览器视图中的标签信息。

就我而言，我错过了eBay开发人员APIAddItem方法Item.PrimaryCategory.CategoryID标签，该方法在文档中不是必需的，但在实际中是必需的。
