Java Spring Boot获取Api响应：Ebay Api

我试图使用Ebay API进行测试，但看起来我并没有得到我想要达到的结果

我在控制器中的@GetMapping请求为：

 @GetMapping(value = "test")
    public ResponseEntity testLogin(){

        RestTemplate restTemplate = new RestTemplate();

        String findCompletedItemsUrl =  "https://svcs.ebay.com/services/search/FindingService/v1?SECURITY-APPNAME=THIS-IS-MY-APP-ID&OPERATION-NAME=findCompletedItems&SERVICE-VERSION=1.0.0&RESPONSE-DATA-FORMAT=JSON&keywords=iphone%20case&categoryId=9355&sortOrder=PricePlusShippingLowest&itemFilter(0).name=Condition&itemFilter(0).value=1000&itemFilter(1).name=SoldItemsOnly&itemFilter(1).value=true&paginationInput.entriesPerPage=10&outputSelector(0)=SellerInfo&GLOBAL-ID=EBAY-US";

        ResponseEntity<String> response = restTemplate.getForEntity(findCompletedItemsUrl, 
         String.class);
        return response;

    }

但是，当我尝试使用上述方法访问同一URL时，没有得到任何结果，count属性显示为0。我得到的json如下所示：

{
  "findCompletedItemsResponse": [
    {
      "ack": [
        "Success"
      ],
      "version": [
        "1.13.0"
      ],
      "timestamp": [
        "2020-03-09T21:57:05.206Z"
      ],
      "searchResult": [
        {
          "@count": "0"
        }
      ],
      "paginationOutput": [
        {
          "pageNumber": [
            "0"
          ],
          "entriesPerPage": [
            "10"
          ],
          "totalPages": [
            "0"
          ],
          "totalEntries": [
            "0"
          ]
        }
      ]
    }
  ]
}
