c# - 有人可以使用 Amazon Web Services 的 itemsearch 提供一个 C# 示例吗

Question

我正在尝试使用 Amazon Web Services 来查询艺术家和标题信息并接收专辑封面。使用 C# 我找不到任何与此类似的示例。所有在线示例都已过时，不适用于 AWS 的较新版本。

Answer 1

CodePlex上有一个开源项目，您可能想看看......它是亚马逊网络服务的 .NET 库。S3、SQS、FPS、EC2 和 DevPay

它可以像这样简单（如 codeplex 所示）：

S3Client s3 = new S3Client("myAWSKey", "MyAWSPassword");

bool success = s3.Connect();

S3Client s3 = new S3Client("key", "secret"):
var buckets = from b in s3.Buckets
                           where b.Name == "demo"
                           select b;
foreach(Bucket b in buckets)
{
     Console.WriteLine(b.About());
}

在这里你去看看它的价值。这是在 Asp.Net 控件中显示书籍信息的代码。您可能可以很容易地根据您的目的调整它。或者至少给你一个起点。如果您真的想要，我很乐意将控件捆绑起来并按照您的方式发送。

if (!(string.IsNullOrEmpty(ISBN) && string.IsNullOrEmpty(ASIN)))
{
    AWSECommerceService service = new AWSECommerceService();
    ItemLookup lookup = new ItemLookup();
    ItemLookupRequest request = new ItemLookupRequest();

    lookup.AssociateTag = ConfigurationManager.AppSettings["AssociatesTag"];
    lookup.AWSAccessKeyId = ConfigurationManager.AppSettings["AWSAccessKey"];
    if (string.IsNullOrEmpty(ASIN))
    {
        request.IdType = ItemLookupRequestIdType.ISBN;
        request.ItemId = new string[] { ISBN.Replace("-", "") };
    }
    else
    {
        request.IdType = ItemLookupRequestIdType.ASIN;
        request.ItemId = new string[] { ASIN };
    }
    request.ResponseGroup = ConfigurationManager.AppSettings["AWSResponseGroups"].Split(new char[] { ' ', ',', ';' }, StringSplitOptions.RemoveEmptyEntries);

    lookup.Request = new ItemLookupRequest[] { request };
    ItemLookupResponse response = service.ItemLookup(lookup);

    if (response.Items.Length > 0 && response.Items[0].Item.Length > 0)
    {
        Item item = response.Items[0].Item[0];
        if (item.MediumImage == null)
        {
            bookImageHyperlink.Visible = false;
        }
        else

            else

            }
        }
        else

        }
        if (item.ItemAttributes.Author != null)
        {
            authorLabel.Text = string.Format("By {0}", string.Join(", ", item.ItemAttributes.Author));
        }
        else
        {
            authorLabel.Text = string.Format("By {0}", string.Join(", ", item.ItemAttributes.Creator.Select(c => c.Value).ToArray()));
        }
        ItemLink link = item.ItemLinks.Where(i => i.Description.Contains("Wishlist")).FirstOrDefault();
        if (link == null)
        {
            wishListHyperlink.Visible = false;
        }
        else

        }
    }
