eBay API findItemsAdvanced() returns 变体列表的重复结果

Question

eBay API 功能

findItemsAdvanced() or findItemsByKeywords()

return 变体列表的所有变体。如何防止同一列表获得多个结果？

目前，我在 eBay 上的页面正在根据 this listing 的变体执行此操作你可以看到结果 here.

如何将变体结果合并为每个列表的一个结果？

这是来自 eBay 的教程显示的代码：

<html>
    <head>
    <title>eBay Search Results</title>
    <style type="text/css">body { font-family: arial,sans-serif;} </style>
    </head> 
    <body>
    <h1>eBay Search Results</h1>

    <div id="results"></div>

    <script>

    // Parse the response and build an HTML table to display search results
    function _cb_findItemsByKeywords(root) {
      var items = root.findItemsByKeywordsResponse[0].searchResult[0].item || [];
      var html = [];
      html.push('<table width="100%" border="0" cellspacing="0" cellpadding="3"><tbody>');
      for (var i = 0; i < items.length; ++i) {
        var item     = items[i];
        var title    = item.title;
        var pic      = item.galleryURL;
        var viewitem = item.viewItemURL;
        if (null != title && null != viewitem) {
          html.push('<tr><td>' + '<img src="' + pic + '" border="0">' + '</td>' + 
          '<td><a href="' + viewitem + '" target="_blank">' + title + '</a></td></tr>');
        }
      }
      html.push('</tbody></table>');
      document.getElementById("results").innerHTML = html.join("");
    }  // End _cb_findItemsByKeywords() function

    // Create a JavaScript array of the item filters you want to use in your request
    var filterarray = [
      {"name":"Seller",
       "value":"gavdials-com"},
      //{"name":"FreeShippingOnly", 
       //"value":"true", 
       //"paramName":"", 
       //"paramValue":""},
      ];


    // Define global variable for the URL filter
    var urlfilter = "";

    // Generates an indexed URL snippet from the array of item filters
    function  buildURLArray() {
      // Iterate through each filter in the array
      for(var i=0; i<filterarray.length; i++) {
        //Index each item filter in filterarray
        var itemfilter = filterarray[i];
        // Iterate through each parameter in each item filter
        for(var index in itemfilter) {
          // Check to see if the paramter has a value (some don't)
          if (itemfilter[index] !== "") {
            if (itemfilter[index] instanceof Array) {
              for(var r=0; r<itemfilter[index].length; r++) {
              var value = itemfilter[index][r];
              urlfilter += "&itemFilter\(" + i + "\)." + index + "\(" + r + "\)=" + value ;
              }
            } 
            else {
              urlfilter += "&itemFilter\(" + i + "\)." + index + "=" + itemfilter[index];
            }
          }
        }
      }
    }  // End buildURLArray() function

    // Execute the function to build the URL filter
    buildURLArray(filterarray);

    // Construct the request
    // Replace MyAppID with your Production AppID
    var url = "http://svcs.ebay.com/services/search/FindingService/v1";
        url += "?OPERATION-NAME=findItemsByKeywords";
        url += "&SERVICE-VERSION=1.0.0";
        url += "&SECURITY-APPNAME=MyAppID";
        url += "&GLOBAL-ID=EBAY-US";
        url += "&RESPONSE-DATA-FORMAT=JSON";
        url += "&callback=_cb_findItemsByKeywords";
        url += "&REST-PAYLOAD";
        url += "&keywords=markers";
        url += "&paginationInput.entriesPerPage=100";
        url += urlfilter;


    // Submit the request 
    s=document.createElement('script'); // create script element
    s.src= url;
    document.body.appendChild(s);

    // Display the request as a clickable link for testing
    document.write("<a href=\"" + url + "\">" + url + "</a>");

    </script>
    </body>

您是否尝试过使用项目过滤器 "HideDuplicateItems"？

另外，以后公开发帖时一定要掩盖您的 eBay API 凭据。
