# 协议

### HTTP

我们的文档包含代码示例，展示如何使用 `HTTP` 协议连接到代理。该协议受常见库和第三方软件支持。

### HTTPS

你也可以使用完全加密的连接，通过 `HTTPS` 协议来额外提升一层安全性。为此，你需要在代理入口地址前添加‘https\://’。例如： `https://isp.oxylabs.io:8001`

<pre class="language-sh"><code class="lang-sh"><strong>curl -x https://isp.oxylabs.io:8000 -U user-USERNAME:PASSWORD https://ip.oxylabs.io/location 
</strong></code></pre>

### SOCKS5

Oxylabs ISP代理支持 `TCP` 和 `UDP` 连接。

要使用 `SOCKS5` 协议，你需要添加 `socks5h://` 到你的代理入口地址。例如： `socks5h://isp.oxylabs.io:8001`

```bash
curl -x socks5h://user-USERNAME:PASSWORD@isp.oxylabs.io:8000 https://ip.oxylabs.io/location
```

{% hint style="info" %}
请注意，某些网站在使用 `SOCKS5` 协议时可能会识别出代理 IP。在这种情况下，我们强烈建议切换到其他协议。
