Amazon Product Advertising API通过Java / SOAP [英] Amazon Product Advertising API through Java/SOAP

问题描述

我一直在玩亚马逊的产品广告API，我无法获得要求通过并向我提供数据。我一直在努力： http://docs.amazonwebservices.com / AWSECommerceService / 2011-08-01 / GSG / 和此：使用Java签署的Amazon Product Advertising API请求

I have been playing with Amazon's Product Advertising API, and I cannot get a request to go through and give me data. I have been working off of this: http://docs.amazonwebservices.com/AWSECommerceService/2011-08-01/GSG/ and this: Amazon Product Advertising API signed request with Java

这是我的代码..我使用以下方法生成了SOAP绑定： http://docs.amazonwebservices.com/AWSECommerceService/2011-08-01/GSG /YourDevelopmentEnvironment.html#Java

Here is my code.. I generated the SOAP bindings using this: http://docs.amazonwebservices.com/AWSECommerceService/2011-08-01/GSG/YourDevelopmentEnvironment.html#Java

在Classpath上，我只有： commons-codec.1.5.jar

On the Classpath, I only have: commons-codec.1.5.jar

import com.ECS.client.jax.AWSECommerceService;
import com.ECS.client.jax.AWSECommerceServicePortType;
import com.ECS.client.jax.Item;
import com.ECS.client.jax.ItemLookup;
import com.ECS.client.jax.ItemLookupRequest;
import com.ECS.client.jax.ItemLookupResponse;
import com.ECS.client.jax.ItemSearchResponse;
import com.ECS.client.jax.Items;

public class Client {

    public static void main(String[] args) {

        String secretKey = <my-secret-key>;
        String awsKey = <my-aws-key>;

        System.out.println("API Test started");

        AWSECommerceService service = new AWSECommerceService();
        service.setHandlerResolver(new AwsHandlerResolver(
                secretKey)); // important
        AWSECommerceServicePortType port = service.getAWSECommerceServicePort();

        // Get the operation object:
        com.ECS.client.jax.ItemSearchRequest itemRequest = new com.ECS.client.jax.ItemSearchRequest();

        // Fill in the request object:
        itemRequest.setSearchIndex("Books");
        itemRequest.setKeywords("Star Wars");
        // itemRequest.setVersion("2011-08-01");
        com.ECS.client.jax.ItemSearch ItemElement = new com.ECS.client.jax.ItemSearch();
        ItemElement.setAWSAccessKeyId(awsKey);
        ItemElement.getRequest().add(itemRequest);

        // Call the Web service operation and store the response
        // in the response object:
        com.ECS.client.jax.ItemSearchResponse response = port
                .itemSearch(ItemElement);

        String r = response.toString();
        System.out.println("response: " + r);

        for (Items itemList : response.getItems()) {
            System.out.println(itemList);
            for (Item item : itemList.getItem()) {
                System.out.println(item);
            }
        }

        System.out.println("API Test stopped");

    }
}

以下是我的回复。我希望看到亚马逊上的一些星球大战书籍被丢弃到我的控制台： - /：

Here is what I get back.. I was hoping to see some Star Wars books available on Amazon dumped out to my console :-/:

API Test started
response: com.ECS.client.jax.ItemSearchResponse@7a6769ea
com.ECS.client.jax.Items@1b5ac06e
API Test stopped

我做错了什么（请注意，第二个for循环中没有item正在打印出来，因为它是空的）？如何解决此问题或获取相关的错误信息？

What am I doing wrong (Note that no "item" in the second for loop is being printed out, because its empty)? How can I troubleshoot this or get relevant error information?

推荐答案

这最终起作用（我必须将我的associateTag添加到请求中）：

This ended up working (I had to add my associateTag to the request):

public class Client {

    public static void main(String[] args) {

        String secretKey = "<MY_SECRET_KEY>";
        String awsKey = "<MY AWS KEY>";

        System.out.println("API Test started");


        AWSECommerceService service = new AWSECommerceService();
        service.setHandlerResolver(new AwsHandlerResolver(secretKey)); // important
        AWSECommerceServicePortType port = service.getAWSECommerceServicePort();

        // Get the operation object:
        com.ECS.client.jax.ItemSearchRequest itemRequest = new com.ECS.client.jax.ItemSearchRequest();

        // Fill in the request object:
        itemRequest.setSearchIndex("Books");
        itemRequest.setKeywords("Star Wars");
        itemRequest.getResponseGroup().add("Large");
//      itemRequest.getResponseGroup().add("Images");
        // itemRequest.setVersion("2011-08-01");
        com.ECS.client.jax.ItemSearch ItemElement = new com.ECS.client.jax.ItemSearch();
        ItemElement.setAWSAccessKeyId(awsKey);
        ItemElement.setAssociateTag("th0426-20");
        ItemElement.getRequest().add(itemRequest);

        // Call the Web service operation and store the response
        // in the response object:
        com.ECS.client.jax.ItemSearchResponse response = port
                .itemSearch(ItemElement);

        String r = response.toString();
        System.out.println("response: " + r);

        for (Items itemList : response.getItems()) {
            System.out.println(itemList);

            for (Item itemObj : itemList.getItem()) {

                System.out.println(itemObj.getItemAttributes().getTitle()); // Title
                System.out.println(itemObj.getDetailPageURL()); // Amazon URL
            }
        }

        System.out.println("API Test stopped");

    }
}
