# POST 请求

[**网页解锁器**](https://github.com/oxylabs/web-unblocker) 不仅支持发送 GET 请求，还允许你向你选择的网页端点发送 POST 请求。你可以向目标网站发送数据，使其返回不同的结果。

#### 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' \
-d 'Your POST JSON: data'
```

{% endtab %}

{% tab title="Python" %}

```python
# 网页解锁器不仅支持发送 GET 请求，还允许你向你选择的网页端点发送 POST 请求。这意味着你可以向目标网站发送数据，然后网站可以返回不同的结果。
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',
}

data = {
    'Your POST JSON': 'data'
}

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

# 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
使用 open('result.html', 'w') 作为 f：
    f.write(response.text)
```

{% endtab %}

```javascript

const headers = {

const body = {

const response = await fetch('https://ip.oxylabs.io/location', {
  method: 'post',
  body: JSON.stringify(body),
  headers: headers,
  agent: agent,

console.log(await 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/post-requests.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.
