通义万相 (Wan) 2.6 API 可视化调用面板

通义万相图像生成模型支持图像编辑、图文混排输出，满足多样化生成与集成需求。

以下是一个基于 React 的通义万相 (Wan) API 可视化调用面板。

效果图：

由于目前通义万相（Wan 2.1/2.0）的视频生成通常是异步任务（提交任务 -> 轮询状态 -> 获取结果），这个面板完整实现了这套全流程逻辑。

核心功能：

1. 配置管理：输入 API Key（存储在本地浏览器内存中，刷新即焚，保证安全）。
2. 参数控制：支持模型选择（预置了 Wan 2.1 等）、提示词、分辨率、时长等参数调节。
3. 任务流处理：自动处理“提交任务”与“轮询进度”的交互逻辑。
4. 调试友好：右侧实时显示发送的 JSON 请求体和 API 返回的原始日志，方便排查问题。

使用说明与注意事项

1. 关于 CORS（跨域）报错：

   • 现象：如果你直接在浏览器运行上述代码并点击生成，可能会在控制台看到Access-Control-Allow-Origin相关的红色报错。
   • 原因：阿里云 DashScope API 出于安全考虑，默认不允许纯浏览器前端直接发起调用（防止你的 API Key 暴露在公网）。
   • 解决方案：
     • 本地测试：你可以安装 Chrome 插件（如 “Allow CORS”）临时绕过限制进行测试。
     • 正式使用：你需要一个简单的后端（Node.js/Python）作为中转，或者使用 Next.js 的 API Route。

2. 模型版本：

   • 代码中预置了wan2.1-t2v-plus，这是目前的旗舰视频模型。如果官方发布了更新的版本（如你提到的 2.6），你只需在左侧下拉菜单选择或直接修改代码中的model参数即可。

3. 如何获取 API Key：

   • 访问 阿里云百炼控制台。
   • 开通 DashScope 服务并创建一个 API Key。
   • 将 Key 粘贴到面板左上角的配置框中即可。

这个面板展示了不使用任何第三方套壳工具，仅用标准的 Web 技术（React + fetch）即可完成与大模型的深度交互。
