#### HTTP

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

#### **SOCKS5** 

要使用 `SOCKS5` 协议，你必须添加 `socks5h` 到你的请求中，例如： 

```
curl -x socks5h://1.2.3.4:1180 -U USERNAME:PASSWORD ip.oxylabs.io
```

#### 代理的端口

代理端口的默认配置包括 `80` 和 `443`，这些是为支持 `HTTP` 和 `HTTPS` 协议而设计的标准端口，如下表所示。要访问其他端口，需要进行合规验证，请联系我们的 [**支持**](mailto:support@oxylabs.io).

| 协议      | 端口    |
| ------- | ----- |
| `HTTP`  | `80`  |
