eBay 交易 API AddItem 调用返回“无效的工作上下文类型”错误

Question

我正在尝试使用 php 和 CURL 使用 Ebay Tradding API 在 ebay 上列出一个项目。

XML 请求和 CURL 语法对我来说似乎很好，但 API 返回 Invalid job context type 错误。

我想我在标题中遗漏了一些东西。

我的请求代码如下：

$xml_string = '<?xml version="1.0" encoding="utf-8"?>
                        <AddItemRequest xmlns="urn:ebay:apis:eBLBaseComponents">

                            <eBayAuthToken>*Token*</eBayAuthToken>
                          </RequesterCredentials>
                          <ErrorLanguage>en_US</ErrorLanguage>

                         </Item>
                        </AddItemRequest>';

        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, "https://api.sandbox.ebay.com/ws/api.dll");
        $headers = array(
            'Content-Type: text/xml',
            'X-EBAY-API-COMPATIBILITY-LEVEL: 967',
            'X-EBAY-API-DEV-NAME: ',
            'X-EBAY-API-APP-NAME: ',
            'X-EBAY-API-CERT-NAME: ',
            'X-EBAY-API-SITEID: 2',
            'X-EBAY-API-CALL-NAME: AddItems'
        );

        curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
        curl_setopt($ch, CURLOPT_POSTFIELDS, "xmlRequest=" . $xml_string);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
        curl_setopt($ch, CURLOPT_HEADER, FALSE);
        curl_setopt($ch, CURLOPT_POST, TRUE);
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 300);

响应是：

<?xml version="1.0" encoding="UTF-8"?>
  <AddItemsResponse xmlns="urn:ebay:apis:eBLBaseComponents">
  <Timestamp>2017-07-28T18:48:59.487Z</Timestamp>

     <ErrorClassification>RequestError</ErrorClassification>
 </Errors><Version>1021</Version><Build>E1021_UNI_API5_18478667_R1</Build></AddItemsResponse>

当我使用 API Explorer 尝试相同的 XML 时。请求已通过。

我认为 CURL 存在一些问题。

Answer 1

您将 X-EBAY-API-CALL-NAME 指定为 AddItems

您的 XML 是一个 AddItemRequest

这些必须匹配。 AddItem 和 AddItems 是 2 个不同的调用。
