在我的web應用程序做亞馬遜API「ItemLookup的要求,得到響應,比如我想獲得在amazon.com上的「iPhone 7」所有可用ASINs,我的要求是這樣的:亞馬遜API ItemLookup響應解析
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類:
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;
}
所以我得到的響應爲XML文檔。 一切都好,但我想知道爲什麼我得到最多10個ASIN?如果我檢查文檔的TotalResults屬性,必須有10000個以上的結果,但是作爲迴應,我只能看到10個結果?我怎樣才能得到別人?
