使用Asp.net的Amazon圖書搜索API

Question

amazon API如何使用asp.net使用ISBN號碼來搜索圖書？

Answer 1

http://webservices.amazon.com/AWSECommerceService/AWSECommerceService.wsdl 使用svcutil.exe爲以上給定的url創建代理 然後這是GetBookByISBN的方法。 AmazonBook是我必須創建自己的DTO DTO。

public static AmazonBook GetBookByISBN(string ISBN) 
    { 
     WebConfigHelper wch = new WebConfigHelper("AWSSettings"); 
     AmazonBook book = null; 
     string AWSAccessKeyId = wch["AccessKey"]; 
     string AssociateTag = wch["AssociateTag"]; 
     string AWSSecKey = wch["SecretKey"]; 

     BasicHttpBinding binding = new BasicHttpBinding(BasicHttpSecurityMode.Transport); 
     binding.MaxReceivedMessageSize = int.MaxValue; 

     AWSECommerceServicePortTypeClient client = new AWSECommerceServicePortTypeClient(
      binding, 
      new EndpointAddress("https://webservices.amazon.com/onca/soap?Service=AWSECommerceService")); 

     // add authentication to the ECS client 
     client.ChannelFactory.Endpoint.Behaviors.Add(new AmazonSigningEndpointBehavior(AWSAccessKeyId, AWSSecKey)); 


     ItemSearchRequest request = new ItemSearchRequest(); 
     request.SearchIndex = "Books"; 
     request.Power = "ISBN:" + ISBN.Trim(); 
     request.ResponseGroup = new string[] { "Large" }; 
     request.Sort = "salesrank"; 

     ItemSearchRequest[] requests = new ItemSearchRequest[] { request }; 

     ItemSearch itemSearch = new ItemSearch(); 
     itemSearch.AWSAccessKeyId = AWSAccessKeyId; 
     itemSearch.AssociateTag = AssociateTag; 
     itemSearch.Request = requests; 


     try 
     { 
      ItemSearchResponse response = client.ItemSearch(itemSearch); 
      Items info = response.Items[0]; 
      if (info.Item != null) 
      { 
       Item[] items = info.Item; 
       if (items.Length == 1) 
       { 
        book = new AmazonBook(items[0]); 
       } 
      } 
     } 
     catch (Exception ex) 
     { 
      throw ex; 
     } 
     return book; 


    }

你可以使用這個庫Nager.AmazonProductAdvertising才能安裝容易的NuGet。該庫還支持.NET 2.0標準

你可以在這裏找到一個asp.net Website實現示例

PM> Install-Package Nager.AmazonProductAdvertising 

短的例子：

var authentication = new AmazonAuthentication(); 
authentication.AccessKey = "accesskey"; 
authentication.SecretKey = "secretkey"; 

var wrapper = new AmazonWrapper(authentication, AmazonEndpoint.US); 
//The Lord of the Rings 
var result = wrapper.Lookup("978-0261102385");
