# 会话

如果您想使用同一个代理发起多个请求，您可以添加 `X-Oxylabs-Session-Id` 标头，并在会话 ID 中使用一个随机生成的字符串。我们将为此 ID 分配一个单独的代理，并在接下来的最多 10 分钟内将其用于所有后续请求。之后，我们会为该特定会话 ID 分配一个新的代理。

为了获得最佳的网站解锁效果，网页解锁器采用预定义会话。请 **避免发送任何常用于解锁的自定义参数**，因为它们可能会干扰网页解锁器获取高质量数据的能力。

#### 代码示例

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

```shell
curl -k -v -x https://unblock.oxylabs.io:60000 \
-U 'USERNAME:PASSWORD' \
'https://ip.oxylabs.io/location' \
-H 'X-Oxylabs-Session-Id: 123randomString'
```

{% endtab %}

{% tab title="Python" %}

```python
import requests

# 在此处使用您的网页解锁器凭据。
用户名，密码 = 'YOUR_USERNAME', 'YOUR_PASSWORD'

# 定义代理字典。
代理 = {
  'http': f'http://{USERNAME}:{PASSWORD}@unblock.oxylabs.io:60000',
  'https': f'https://{USERNAME}:{PASSWORD}@unblock.oxylabs.io:60000',
}

headers = {
    'X-Oxylabs-Session-Id': '123randomString'
}

response = requests.get(
    'https://ip.oxylabs.io/location',
    verify=False，# 需要忽略证书
    代理=代理,
    headers=headers,
)

# 将结果页打印到标准输出
print(response.text)

# 将返回的 HTML 保存到 result.html 文件
with open('result.html', 'w') as f:
    f.write(response.text)

# 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/products/cn/web-unblocker/making-requests/session.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.
