Java

Product product = new Product();

product.setOfferId("book123");
product.setTitle("A Tale of Two Cities");
product.setDescription("A classic novel about the French Revolution");
product.setLink("http://my-book-shop.com/tale-of-two-cities.html");
product.setImageLink("http://my-book-shop.com/tale-of-two-cities.jpg");
product.setContentLanguage("en");
product.setTargetCountry("GB");
product.setChannel("online");
product.setAvailability("in stock");
product.setCondition("new");
product.setGoogleProductCategory("Media > Books");
product.setGtin("9780007350896");

Price price = new Price();
price.setValue("2.50");
price.setCurrency("GBP");
product.setPrice(price);

Price shippingPrice = new Price();
shippingPrice.setValue("0.99");
shippingPrice.setCurrency("GBP");

ProductShipping shipping = new ProductShipping();
shipping.setPrice(shippingPrice);
shipping.setCountry("GB");
shipping.setService("Standard shipping");

ArrayList shippingList = new ArrayList();
shippingList.add(shipping);
product.setShipping(shippingList);

Product result = service.products().insert(merchantId, product).execute();

PHP

$product = new Google_Service_ShoppingContent_Product();
$product->setOfferId('book123');
$product->setTitle('A Tale of Two Cities');
$product->setDescription('A classic novel about the French Revolution');
$product->setLink('http://my-book-shop.com/tale-of-two-cities.html');
$product->setImageLink('http://my-book-shop.com/tale-of-two-cities.jpg');
$product->setContentLanguage('en');
$product->setTargetCountry('GB');
$product->setChannel('online');
$product->setAvailability('in stock');
$product->setCondition('new');
$product->setGoogleProductCategory('Media > Books');
$product->setGtin('9780007350896');

$price = new Google_Service_ShoppingContent_Price();
$price->setValue('2.50');
$price->setCurrency('GBP');

$shipping_price = new Google_Service_ShoppingContent_Price();
$shipping_price->setValue('0.99');
$shipping_price->setCurrency('GBP');

$shipping = new Google_Service_ShoppingContent_ProductShipping();
$shipping->setPrice($shipping_price);
$shipping->setCountry('GB');
$shipping->setService('Standard shipping');

$shipping_weight = new Google_Service_ShoppingContent_ProductShippingWeight();
$shipping_weight->setValue(200);
$shipping_weight->setUnit('grams');

$product->setPrice($price);
$product->setShipping(array($shipping));
$product->setShippingWeight($shipping_weight);

$result = $service->products->insert($merchant_id, $product);

获取商品列表

要获取商品列表，请使用以下代码：

协议

GET /content/v2/YOUR_MERCHANT_ID/products

Java

List productsList = service.products().list(merchantId);

ProductsListResponse page = productsList.execute();
while ((page.getResources() != null) && !page.getResources().isEmpty()) {
  for (Product product : page.getResources()) {
    System.out.printf("%s %s%n", product.getId(), product.getTitle());
  }

  if (page.getNextPageToken() == null) {
    break;
  }

  productsList.setPageToken(page.getNextPageToken());
  page = productsList.execute();
}

PHP

$products = $service->products->listProducts($merchantId);
$parameters = array();
while (!empty($products->getResources()) {
  foreach ($products->getResources() as $product) {
    printf("%s %s\n", $product->getId(), $product->getTitle());
  }
  if (!empty($products->getNextPageToken()) {
    break;
  }
  $parameters['pageToken'] = $products->nextPageToken;
  $products = $service->products->listProducts($merchantId, $parameters);
}

检索特定商品

要从列表中检索特定商品，请使用以下代码：

协议

GET /content/v2/YOUR_MERCHANT_ID/products/online:en:GB:book123

Java

Product product = service.products()
    .get(merchantId, "online:en:GB:book123")
    .execute();
System.out.printf("%s %s\n", product.getId(), product.getTitle());

PHP

$product = $service->products->get($merchant_id, 'online:en:GB:book123');
printf("%s %s\n", $product->getId(), $product->getTitle());

更新商品价格

您可以利用 Inventory 服务，使用以下代码更新价格和库存状况：

协议

POST /content/v2/YOUR_MERCHANT_ID/inventory/online/products/online:en:GB:book123

{
  "price": {
    "value": "3.99",
    "currency": "USD"
  }
}

Java

InventorySetRequest inventory = new InventorySetRequest();

Price price = new Price();
price.setValue('3.99');
price.setCurrency('USD');

inventory.setPrice(price);

service.inventory()
    .set(merchantId, "online", "online:en:US:book1", inventory)
    .execute();

PHP

$inventory = new Google_Service_ShoppingContent_InventorySetRequest();

$price = new Google_Service_ShoppingContent_Price();
$price->setValue('3.99');
$price->setCurrency('USD');

$inventory->setPrice($price);

$service->inventory->set(merchant_id, 'online', 'online:en:US:book1', $inventory);
