# URL

该 `沃尔玛` source 的设计用于检索各类沃尔玛页面的直接 URL 内容。您无需发送多个参数，只需为所需的沃尔玛页面提供一个直接 URL 即可。我们不会移除任何参数，也不会以任何其他方式更改您的 URL。

{% hint style="success" %}
解析仅限于 [搜索页面](https://developers.oxylabs.io/scraping-solutions/web-scraper-api/targets/walmart/search) 和 [产品页面](https://developers.oxylabs.io/scraping-solutions/web-scraper-api/targets/walmart/product). 

对于其他页面类型，我们可以返回 HTML 内容。您可以轻松地 [**构建你自己的解析器**](broken://pages/1020d1e5b4bde02bde3e51d8471fe9dbed215fea) 如果你想获取 JSON 结构化数据。

### 请求样本

下面的示例说明了如何获取沃尔玛页面。

{% tabs %}
{% tab title="cURL" %}

```shell
curl 'https://realtime.oxylabs.io/v1/queries' \\
--user 'USERNAME:PASSWORD' \\
-H 'Content-Type: application/json' \\
-d '{
        "source": "walmart",
        "url": "https://www.walmart.com/cp/new-arrivals/2593086"
    }'
```

{% endtab %}

{% tab title="Python" %}

```python
import requests
from pprint import pprint


# 结构化负载。
payload = {
    "source": "walmart",
    "url": "https://www.walmart.com/cp/new-arrivals/2593086"
}

# 获取响应。
response = requests.request(
    'POST',
    'https://realtime.oxylabs.io/v1/queries',
    auth=('USERNAME', 'PASSWORD'),
    json=payload
)

# 不会返回作业状态和结果 URL 的响应，而是会返回
# 包含结果的 JSON 响应。
pprint(response.json())
```

{% endtab %}

{% tab title="Node.js" %}

```javascript
const https = require("https");

    });
});

request.on("error", (error) => {
    console.error("错误：", error);
});

request.write(JSON.stringify(body));
request.end();
```

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://developers.oxylabs.io/api-targets/cn/dian-zi-shang-wu/walmart/url.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
