在我的web应用程序做亚马逊API“ItemLookup的要求,得到响应,比如我想获得在amazon.com上的“iPhone 7”所有可用ASINs,我的要求是这样的:亚马逊API ItemLookup响应解析
public class Application {
public static void main(String[] args) {
List<String> foundASINs = new ArrayList<>();
Map<String, String> params = new HashMap<>();
params.put("Operation", "ItemSearch");
params.put("ResponseGroup", "ItemIds");
params.put("Keywords", "iphone 7");
params.put("SearchIndex", "Wireless");
AwsRequest request = new AwsRequest();
String res="";
try {
request.getRequest(params);
和AwsRequest类:
public Document getRequest (Map<String, String> params) throws IOException, NoSuchAlgorithmException, InvalidKeyException, ParserConfigurationException, SAXException {
params.put("Service", "AWSECommerceService");
params.put("AssociateTag", ASSOCIATE_TAG);
params.put("Version", "2016-09-27");
SignedRequestsHelper helper = SignedRequestsHelper.getInstance(ENDPOINT, AWS_ACCESS_KEY_ID, AWS_SECRET_KEY);
String requestUrl = helper.sign(params);
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
doc = db.parse(requestUrl);
return doc;
}
所以我得到的响应为XML文档。 一切都好,但我想知道为什么我得到最多10个ASIN?如果我检查文档的TotalResults属性,必须有10000个以上的结果,但是作为回应,我只能看到10个结果?我怎样才能得到别人?
