product.setTargetCountry("GB");
product.setChannel("online");
product.setAvailability("in stock");
product.setCondition("new");

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');

获取商品列表

要获取使用以下代码：

协议

GET /content/v2.1/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);
}

    .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());

更新在线商品库存状况

product.setOfferId("book123");
product.setContentLanguage("en");
product.setTargetCountry("GB");
product.setChannel("online");

// Optional Fields to Update

feedId=123456789

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

PHP
