c# - 誰かが Amazon Web Services の itemsearch を使用して C# の例を提供できますか?

Question

Amazon Web Services を使用して、アーティストとタイトルの情報をクエリし、アルバム アートを受信しようとしています。C# を使用すると、これに近い例が見つかりません。オンラインの例はすべて古く、AWS の新しいバージョンでは機能しません。

Answer 1

CodePlexにはオープン ソース プロジェクトがあります。ぜひご覧ください。これは、Amazon の Web サービス用の .NET ライブラリです。S3、SQS、FPS、EC2、DevPay

次のように簡単にできます (codeplex に示されているように):

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());
}

Answer 2

Here you go for what it's worth. This is code within an Asp.Net control to display book information. You can probably adapt it for your purposes easily enough. Or at least give you a starting-point. If you really want, I'd be happy to bundle the control up and send it your way.

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
        {
            bookImageHyperlink.ImageUrl = item.MediumImage.URL;
        }
        bookImageHyperlink.NavigateUrl = item.DetailPageURL;
        bookTitleHyperlink.Text = item.ItemAttributes.Title;
        bookTitleHyperlink.NavigateUrl = item.DetailPageURL;
        if (item.OfferSummary.LowestNewPrice == null)
        {
            if (item.OfferSummary.LowestUsedPrice == null)
            {
                priceHyperlink.Visible = false;
            }
            else
            {
                priceHyperlink.Text = string.Format("Buy used {0}", item.OfferSummary.LowestUsedPrice.FormattedPrice);
                priceHyperlink.NavigateUrl = item.DetailPageURL;
            }
        }
        else
        {
            priceHyperlink.Text = string.Format("Buy new {0}", item.OfferSummary.LowestNewPrice.FormattedPrice);
            priceHyperlink.NavigateUrl = item.DetailPageURL;
        }
        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
        {
            wishListHyperlink.NavigateUrl = link.URL;
        }
    }
}
