// 方式一：本地引入（下载 SDK 文件后放置到项目中）
import { IceShuttle, downloadBlob } from './sdk/iceshuttle.esm.js';

// 方式二：官网下载引入（适合无构建工具的项目）
// 下载地址：https://www.wringcloud.com/sdk/iceshuttle-js/dist/iceshuttle.min.js
<script src="./sdk/iceshuttle.min.js"></script>

import { IceShuttle } from 'iceshuttle-js';

const client = new IceShuttle({
  appKey: 'your-app-key',         // 必填：应用 Key
  appSecret: 'your-app-secret',   // 必填：应用 Secret
  serverDomain: 'https://www.wringcloud.com',  // 可选：服务器地址
  debug: false                       // 可选：是否开启调试日志
});

// 1. 创建 P2P 发送任务
const sender = await client.createP2PSender({
  fileName: file.name,             // 必填：文件名
  fileSize: file.size,             // 必填：文件大小（字节）
  password: '可选密码',            // 可选：传输密码
  maxReceiveCount: 1              // 可选：最大接收次数
});

// 2. 获取接收链接，分享给接收方
const receiveLink = sender.getReceiveLink();
console.log('接收链接:', receiveLink);

// 3. 发送文件（SDK 自动等待接收方连接并传输）
await sender.sendFile(file, {
  onProgress: (percent) => {

// 4. 取消传输（可选）
await sender.cancel();

// 从接收链接中解析 transferId 和 token
const receiver = await client.createP2PReceiver(transferId, token);

// 获取文件信息

// 1. 创建安全中转任务

  fileSize: file.size,             // 必填：文件大小（字节）
  password: '可选密码',            // 可选：传输密码
  maxReceiveCount: 5,             // 可选：最大下载次数
  expireHours: 168               // 可选：链接有效期（小时）
});

// 2. 获取下载链接，分享给接收方
const downloadLink = sender.getDownloadLink();

// 3. 上传文件（SDK 自动处理分块上传）
await sender.sendFile(file, {

// 从下载链接中解析 transferId 和 token

// 获取文件信息

// 下载文件为 Blob

// 查询 P2P 传输状态

const relayStatus = await client.getRelayTransferStatus(transferId);

// 取消 P2P 传输
await client.cancelP2PTransfer(transferId);

// 取消安全中转传输

// 或直接调用 sender.cancel()
await sender.cancel();
