# 请求头与 Cookie

网页解锁器通过使用我们团队预先定义的标头和 Cookie，最大化网站解锁效率。

### 自定义标头

如果您需要使用自己的标头，可以通过添加以下内容来实现 `x-oxylabs-force-headers: 1` 标头到您的请求中。网页解锁器会将您的自定义标头合并到预定义的标头集中，然后使用它来访问网站。

#### 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

# 在这里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,
)

# 将结果页面打印到标准输出
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)
```

### 自定义 Cookie

如果您需要使用自己的 Cookie，您可以通过添加 `x-oxylabs-force-Cookie:1` 请求中的 header。网页解锁器会将你的自定义 Cookie 合并到预定义的 Cookie 集中，然后使用它来访问该网站。

#### 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

# 在这里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
)

# 将结果页面打印到标准输出
print(response.text)

# 将返回的 HTML 保存到 result.html 文件

# 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/headers.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.
