# 请求头与 Cookie

网页解锁器通过使用我们团队预定义的请求头和Cookie来优化数据访问。

### 自定义请求头

如果你需要使用自己的请求头，可以通过添加 `x-oxylabs-force-headers: 1` 将其添加到你的请求中。网页解锁器会把你的自定义请求头合并到预定义的请求头集合中，然后用它来访问网站。

#### 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/headers' \
-H 'x-oxylabs-force-headers: 1' \
-H 'Accept-Language: en-GB' \
-H 'Your-Header-Name: interesting header content'
```

{% endtab %}

{% tab title="Python" %}

```python
import requests

# 在此使用你的网页解锁器凭据。
USERNAME, PASSWORD = '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-force-headers': '1',
    'Accept-Language': 'en-GB',
    'Your-Header-Name': 'interesting header content'
}

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

# Print result page to stdout
print(response.text)

# Save returned HTML to result.html file
with open('result.html', 'w') as f:
    f.write(response.text)
```

{% endtab %}

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

### 自定义 Cookie

如果你需要使用自己的 Cookie，可以通过添加以下内容 `x-oxylabs-force-Cookie:1` 请求中的标头。网页解锁器会将你的自定义 Cookie 合并到预定义的 Cookie 集中，然后用它来访问网站。

#### 代码示例

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

```shell
curl -k -v -x https://unblock.oxylabs.io:60000 \
-U 'USERNAME:PASSWORD' \
'https://example.com' \
--Cookie 'NID=1234567890' \
-H 'x-oxylabs-force-Cookie: 1'
```

{% endtab %}

{% tab title="Python" %}

```python
import requests

# 在此使用你的网页解锁器凭据。
USERNAME, PASSWORD = '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 = {
    'Cookie': 'NID=1234567890',
    'x-oxylabs-force-Cookie': '1' 
}

response = requests.get(
    'https://example.com',
    代理=代理,
    headers=headers,
    verify=False  # 忽略证书验证
)

# Print result page to stdout
print(response.text)

# Save returned HTML to result.html file

    f.write(response.text)
```

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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, and the optional `goal` query parameter:

```
GET https://developers.oxylabs.io/products/cn/web-unblocker/making-requests/headers.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
