# POST 请求

[**网页解锁器**](https://github.com/oxylabs/web-unblocker) 不仅支持发送 GET 请求，还允许你向所选的网络端点发送 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 %}

```python
# Web Unblocker 不仅支持发送 GET 请求，还允许你向所选的网络端点发送 POST 请求。这意味着你可以向目标网站发送数据，从而使网站返回不同的结果。
import requests

# 在此处使用你的 Web Unblocker 凭证。
USERNAME, PASSWORD = 'YOUR_USERNAME', 'YOUR_PASSWORD'

# 定义代理字典。
proxies = {
  '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
    proxies=proxies,
    json=data,
)

# 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)
```
