|
||||
|
||||
### ✨ Added
|
||||
- **故障转移系统**
|
||||
- 实现了基于 Pool 的自动故障转移：当某个 Worker 执行任务失败（如 API 超时、页面崩溃、被限流）时，系统会自动寻找下一个支持该模型的 Worker 进行重试。
|
||||
- **Merge 模式增强**：Merge Worker 内部也会在不同的适配器之间进行故障转移。
|
||||
|
||||

||||
- **行为说明**：
|
||||
- **流式请求 (stream: true)**：支持无限排队，并通过心跳机制保持连接以等待结果。
|
||||
- **非流式请求**：在队列未满时正常处理；当队列满时，将立即拒绝并返回明确的拒绝原因，但仍受 `maxQueueSize` 限制。

### 🔄 Changed
|
||||
- **流式接口优化**
|
||||
- 移除了全局开关，改为由请求体参数 `stream: true` 动态控制。
|
||||
- **保活机制**：流式模式下支持无限排队，并通过 SSE 心跳包防止连接超时。
|
||||
- **拒绝策略**：非流式请求在队列满时立即拒绝，避免无限等待。
