Question

我使用以下代码使用Ebay的FindingAPI来获取Ebay匹配关键字的所有项目链接。在这种情况下，“gruen watch”是关键字。此代码不会显示超过100个项目的链接。如何修改它以显示所有项链接？

**我已经取代原来的appid

Program.cs的

namespace ConsoleApplication1
{

class Program
{

    static void Main(string[] args)
    {

        TextWriter tw = new StreamWriter("link.txt");
        using (FindingServicePortTypeClient client = new FindingServicePortTypeClient())
        {

            MessageHeader header = MessageHeader.CreateHeader("My-CustomHeader", "http://www.mycustomheader.com", "Custom Header");
            using (OperationContextScope scope = new OperationContextScope(client.InnerChannel))
            {

                OperationContext.Current.OutgoingMessageHeaders.Add(header);
                HttpRequestMessageProperty httpRequestProperty = new HttpRequestMessageProperty();
                httpRequestProperty.Headers.Add("X-EBAY-SOA-SECURITY-APPNAME", "MY-APP-ID");
                httpRequestProperty.Headers.Add("X-EBAY-SOA-OPERATION-NAME", "findItemsByKeywords");
                httpRequestProperty.Headers.Add("X-EBAY-SOA-GLOBAL-ID", "EBAY-US");
                OperationContext.Current.OutgoingMessageProperties[HttpRequestMessageProperty.Name] = httpRequestProperty;


                FindItemsByKeywordsRequest request = new FindItemsByKeywordsRequest();
                request.keywords = "gruen watch";

                PaginationInput pagination = new PaginationInput();
                pagination.entriesPerPageSpecified = true;
                pagination.entriesPerPage = 250;
                pagination.pageNumberSpecified = true;
                pagination.pageNumber = 10;
                request.paginationInput = pagination;




                FindItemsByKeywordsResponse response = client.findItemsByKeywords(request);


                foreach (var item in response.searchResult.item)
                {

                    //Console.WriteLine(item.title);
                    tw.WriteLine(item.viewItemURL.ToString());
                    Console.WriteLine(item.viewItemURL.ToString());

                }


            }

        }

        tw.Close();

        Console.ReadKey();

    }

}

app.config是here

这是我所做的解决方案：

namespace ConsoleApplication1

{ 



class Program

{



    static void Main(string[] args)

    {



        TextWriter tw = new StreamWriter("1001.txt");

        using (FindingServicePortTypeClient client = new FindingServicePortTypeClient())

        {



            MessageHeader header = MessageHeader.CreateHeader("My-CustomHeader", "http://www.mycustomheader.com", "Custom Header");

            using (OperationContextScope scope = new OperationContextScope(client.InnerChannel))

            {



                OperationContext.Current.OutgoingMessageHeaders.Add(header);

                HttpRequestMessageProperty httpRequestProperty = new HttpRequestMessageProperty();

                httpRequestProperty.Headers.Add("X-EBAY-SOA-SECURITY-APPNAME", "MYAPPID");

                httpRequestProperty.Headers.Add("X-EBAY-SOA-OPERATION-NAME", "findItemsByKeywords");

                httpRequestProperty.Headers.Add("X-EBAY-SOA-GLOBAL-ID", "EBAY-US");

                OperationContext.Current.OutgoingMessageProperties[HttpRequestMessageProperty.Name] = httpRequestProperty;





                FindItemsByKeywordsRequest request = new FindItemsByKeywordsRequest();



                request.keywords = "gruen watch";

                FindItemsByKeywordsResponse check = client.findItemsByKeywords(request);

                int totalEntries = check.paginationOutput.totalEntries;

                int cnt = 0;

                int totalPages = (int)Math.Ceiling((double)totalEntries/100.00);



                bool flag = true;



                for (int curPage = 1; curPage <= totalPages; curPage++)

                {

                    PaginationInput pagination = new PaginationInput();



                    pagination.entriesPerPageSpecified = true;

                    pagination.entriesPerPage = 100;

                    pagination.pageNumberSpecified = true;

                    pagination.pageNumber = curPage;

                    request.paginationInput = pagination;



                    FindItemsByKeywordsResponse response = client.findItemsByKeywords(request);





                    foreach (var item in response.searchResult.item)

                    {

                        Console.WriteLine(item.viewItemURL.ToString());

                        tw.WriteLine(item.viewItemURL.ToString());

                    }

                }















            }



        }



        tw.Close();

        Console.WriteLine("end");

        Console.ReadKey();



    }



}



}

默认情况下，响应返回第一页数据，最多返回100个项目。您可以使用paginationInput更改此值。

在official eBay documentation for findItemsByKeywords上，有一个名为将结果分页的部分，它可以告诉您确切需要知道的内容：

使用paginationInput及其子元素来控制在结果集中返回与搜索条件匹配的项目集。使用paginationInput将返回的项目划分为数据的子集或“页面”：

paginationInput.entriesPerPage 指定最大商品数   返回任何给定的请求

paginationInput.pageNumber 指定   在当前通话中返回哪个“页面”数据

默认情况下，   响应返回第一页数据，最多返回100个项目。   以下示例显示如何返回结果的第二页，   每页最多包含50个项目：

...&paginationInput.pageNumber=2&paginationInput.entriesPerPage=50...

在此示例中，响应将包含匹配项51到100，假设至少有100个匹配项。
