# 高带宽代理

## 快速开始

要开始使用我们的 [**高带宽代理** ](https://oxylabs.io/products/high-bandwidth-proxies)用于 视频数据和音频抓取，请联系销售团队以获取您的专用端点。每位客户都会获得为其特定需求配置的唯一代理端点。要将此解决方案直接与 `yt_dlp` 库集成，请参阅此页面：

{% endcontent-ref %}

## 端点配置

在从客户管理团队收到您的端点后，您将获得：

* 一个专用代理端点
* 您的用户名和密码
* 端口号（默认：60000）

## 发起请求

要快速检查连接，请在用户名中添加 `-test` 参数。

### 为每次下载设置会话

为确保最佳成功率，高带宽代理在每个会话期间提供自动负载均衡。该 `-$((1 + RANDOM % 100000))`  用户名旁的参数会生成一个随机数作为会话 ID，并为每次下载分配不同的 IP 地址。&#x20;
