我在理解如何使用 amazon mws java 库时遇到问题。我能够实现它，我可以调用 ListMatchingProducts 并将一些 xml 打印到控制台中。但是我如何从中获取部分内容，例如产品标题？ 我刚开始编程，可能我只是不了解这里的 api 使用的一些基础知识。 请帮帮我。 这就是我调用搜索方法的方式:
searchF.setOnAction(new EventHandler<ActionEvent>() {
@Override
public void handle(ActionEvent event) {
AmazonSearch.amazonSearch(searchF.getText());
}
});
这是我想使用的亚马逊 api 类的摘录:
invokeListMatchingProducts(service, request);
}
public static ListMatchingProductsResponse response;
public static void invokeListMatchingProducts(MarketplaceWebServiceProducts service,
ListMatchingProductsRequest request) {
try {
response = service.listMatchingProducts(request);
System.out.println ("ListMatchingProducts Action Response");
System.out.println ("=============================================================================");
System.out.println ();
System.out.println(" ListMatchingProductsResponse");
System.out.println();
if (response.isSetListMatchingProductsResult()) {
System.out.println(" ListMatchingProductsResult");
System.out.println();
ListMatchingProductsResult listMatchingProductsResult = response.getListMatchingProductsResult();
if (listMatchingProductsResult.isSetProducts()) {
System.out.println(" Products");
System.out.println();
ProductList products = listMatchingProductsResult.getProducts();
java.util.List<Product> productList = products.getProduct();
for (Product product : productList) {
System.out.println(" Product");
System.out.println();
if (product.isSetIdentifiers()) {
System.out.println(" Identifiers");
System.out.println();
IdentifierType identifiers = product.getIdentifiers();
if (identifiers.isSetMarketplaceASIN()) {
System.out.println(" MarketplaceASIN");
System.out.println();
ASINIdentifier marketplaceASIN = identifiers.getMarketplaceASIN();
if (marketplaceASIN.isSetMarketplaceId()) {
System.out.println(" MarketplaceId");
System.out.println();
System.out.println(" " + marketplaceASIN.getMarketplaceId());
System.out.println();
}
if (marketplaceASIN.isSetASIN()) {
System.out.println(" ASIN");
System.out.println();
System.out.println(" " + marketplaceASIN.getASIN());
System.out.println();
}
}
if (identifiers.isSetSKUIdentifier()) {
System.out.println(" SKUIdentifier");
System.out.println();
SellerSKUIdentifier SKUIdentifier = identifiers.getSKUIdentifier();
if (SKUIdentifier.isSetMarketplaceId()) {
System.out.println(" MarketplaceId");
System.out.println();
System.out.println(" " + SKUIdentifier.getMarketplaceId());
System.out.println();
}
if (SKUIdentifier.isSetSellerId()) {
System.out.println(" SellerId");
System.out.println();
System.out.println(" " + SKUIdentifier.getSellerId());
System.out.println();
}
if (SKUIdentifier.isSetSellerSKU()) {
System.out.println(" SellerSKU");
System.out.println();
System.out.println(" " + SKUIdentifier.getSellerSKU());
System.out.println();
}
}
}
if (product.isSetAttributeSets()) {
System.out.println(" Attributes");
AttributeSetList attributeSetList = product.getAttributeSets();
for (Object obj : attributeSetList.getAny()) {
Node attribute = (Node) obj;
System.out.println(ProductsUtil.formatXml(attribute));
}
System.out.println();
}
...
}
}
}
if (response.isSetResponseMetadata()) {
System.out.println(" ResponseMetadata");
System.out.println();
ResponseMetadata responseMetadata = response.getResponseMetadata();
if (responseMetadata.isSetRequestId()) {
System.out.println(" RequestId");
System.out.println();
System.out.println(" " + responseMetadata.getRequestId());
System.out.println();
}
}
System.out.println();
System.out.println(response.getResponseHeaderMetadata());
System.out.println();
} catch (MarketplaceWebServiceProductsException ex) {
System.out.println("Caught Exception: " + ex.getMessage());
System.out.println("Response Status Code: " + ex.getStatusCode());
System.out.println("Error Code: " + ex.getErrorCode());
System.out.println("Error Type: " + ex.getErrorType());
System.out.println("Request ID: " + ex.getRequestId());
System.out.println("XML: " + ex.getXML());
System.out.print("ResponseHeaderMetadata: " + ex.getResponseHeaderMetadata());
}
}
}
最佳答案
我自己搞定了。我只需要访问 public static ListMatchingProductsResponse response; 并将其转换为 xml。其实没那么难。
