# 协议

ISP代理支持 HTTP、HTTPS 和 SOCKS5 协议。了解如何为安全且多样化的任务配置这些协议。

### HTTP

我们的文档包含代码示例，展示如何使用 `HTTP` 协议。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，采用 `HTTPS` 用于额外安全层的协议。为此，您需要在代理入口添加 ‘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代理支持这两种协议 `TCP` 和 `UDP` 连接。

要使用 `SOCKS5` 协议，你需要添加 `socks5h://` 到你的代理入口点。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，某些网站在使用该协议时可能会识别出代理 IP `SOCKS5` 协议。我们强烈建议在这种情况下切换到其他协议。

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://developers.oxylabs.io/products/cn/proxies/isp-proxies/protocols.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
