# 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

你还可以使用完全加密的连接通过以下方式连接到代理： `HTTPS` 协议。为此，你需要添加 `https://` 到您的代理入口点。例如： `https://dc.oxylabs.io:8000`

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

### SOCKS5

SOCKS5 协议支持这两种 `TCP` 和 `UDP` 连接。

要使用 `SOCKS5` 协议，您需要添加 `socks5h://` 到您的代理入口点。例如： `socks5h://dc.oxylabs.io:8000`

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