Google Shopping 来源旨在通过 `google_shopping_search` 和 `google_shopping_product` 来源分别收集 SERP 和商品列表数据。数据提取是一个如下所示的两步过程。

### **步骤 1：生成 Token**

首先，您需要向 `google_shopping_search` [source](/api-targets/cn/sou-suo-yin-qing/google/shopping/shopping-search.md)提交请求。此步骤至关重要，因为它会生成 **商品 token**，这是稍后收集商品数据所必需的。下面是用于 `google_shopping_search` 请求的基本 JSON 载荷：

```json
{
  "source": "google_shopping_search",
  "query": "google_pixel",
  "render": "html",
  "parse": true
}
```

{% hint style="warning" %}
**重要：** 只有已渲染并解析的任务才会返回商品 token。
{% endhint %}

任务完成后，您会在响应中的 `organic` 部分找到该 token：

```json
{
    "results": [
        {
            "content": {
                "url": "https://www.google.com/search?q=google_pixel&gl=us&hl=en&udm=28&sei=1uDkaLnMNPCNxc8P67XmqQg",
                "page": 1,
                "results": {
                    "paid": [],
                    "organic": [
                        {
                            "pos": 1,
                            "url": "https://www.google.com/shopping/product/547163035992318172?q=google_pixel&gl=us&hl=en&udm=28&sei=1uDkaLnMNPCNxc8P67XmqQg&gl=US",
                            "type": "grid",
                            "price": 899,
                            "title": "Google Pixel 9 Pro XL",
                            "token": "eyJjYXRhbG9naWQiOiAiNTQ3MTYzMDM1OTkyMzE4MTcyIiwgImdwY2lkIjogIjQ0MjYwMDg2MDY1MDIwNTc4NTkiLCAiaW1hZ2VEb2NpZCI6ICIxMjMwMTAyNDkzMzk0Mjg2MjY4IiwgIm1pZCI6ICI1NzY0NjI3ODc4NTM5Njc1NDAiLCAicHZvIjogIjIzIiwgInB2dCI6ICJoZyIsICJyZHMiOiAiUENfNDQyNjAwODYwNjUwMjA1Nzg1OXxQUk9EX1BDXzQ0MjYwMDg2MDY1MDIwNTc4NTkiLCAicXVlcnkiOiAiZ29vZ2xlX3BpeGVsIn0=",
```

解析结果中的每个已收集商品 token 都代表一个自然结果。

{% hint style="info" %}
**注意：** 如果没有生成的 token，就无法检索商品或价格信息。
{% endhint %}

### **步骤 2：在商品请求中使用 Token**

要开始收集商品数据，请在您向 `google_shopping_product` [source](/api-targets/cn/sou-suo-yin-qing/google/shopping/shopping-product.md):

```json

{
  "source": "google_shopping_product",
  "query": "eyJjYXRhbG9naWQiOiAiNTQ3MTYzMDM1OTkyMzE4MTcyIiwgImdwY2lkIjogIjQ0MjYwMDg2MDY1MDIwNTc4NTkiLCAiaW1hZ2VEb2NpZCI6ICIxMjMwMTAyNDkzMzk0Mjg2MjY4IiwgIm1pZCI6ICI1NzY0NjI3ODc4NTM5Njc1NDAiLCAicHZvIjogIjIzIiwgInB2dCI6ICJoZyIsICJyZHMiOiAiUENfNDQyNjAwODYwNjUwMjA1Nzg1OXxQUk9EX1BDXzQ0MjYwMDg2MDY1MDIwNTc4NTkiLCAicXVlcnkiOiAiZ29vZ2xlX3BpeGVsIn0=",
  "parse": true
}
```

{% hint style="warning" %}
**重要：** 如果使用了无效或生成错误的 token，任务将失败。
{% endhint %}

在使用 `google_shopping_product` 和 `google_shopping_search` 来源的本地化参数时，请确保使用相同的地区设置（如果未定义，则不使用）。来源之间的地区不匹配可能会导致数据不完整或不准确。
