amazon product advertising api - item lookup request working example
- by I__
would anyone have a working example of an amazon ITEMLOOKUP ?
i have the following code but it does not seem to work:
string ISBN = "0393326381";
string ASIN = "";
if (!(string.IsNullOrEmpty(ISBN) && string.IsNullOrEmpty(ASIN)))
{
AWSECommerceServicePortTypeChannel service = new AWSECommerceServicePortTypeChannel();
ItemLookup lookup = new ItemLookup();
ItemLookupRequest request = new ItemLookupRequest();
lookup.AssociateTag = secretKey;
lookup.AWSAccessKeyId = accessKeyId;
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 = new string[] { "OfferSummary" };
lookup.Request = new ItemLookupRequest[] { request };
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;
}
* */
}
}
}
the problem is with this:
thisshould be defined differently but i do not know how AWSECommerceServicePortTypeChannel service = new AWSECommerceServicePortTypeChannel();
