数据源策略层 - 包初始化
|
||
===================================
|
||
|
||
本包实现策略模式管理多个数据源，实现：
|
||
1. 统一的数据获取接口
|
||
2. 自动故障切换
|
||
3. 防封禁流控策略
|
||
|
||
数据源优先级（动态调整）：
|
||
【配置了 TUSHARE_TOKEN 时】
|
||
1. TushareFetcher (Priority 0) - 🔥 最高优先级（动态提升）
|
||
2. EfinanceFetcher (Priority 0) - 同优先级
|
||
3. AkshareFetcher (Priority 1) - 来自 akshare 库
|
||
4. PytdxFetcher (Priority 2) - 来自 pytdx 库（通达信）
|
||
5. BaostockFetcher (Priority 3) - 来自 baostock 库
|
||
6. YfinanceFetcher (Priority 4) - 来自 yfinance 库
|
||
|
||
【未配置 TUSHARE_TOKEN 时】
|
||
1. EfinanceFetcher (Priority 0) - 最高优先级，来自 efinance 库
|
||
2. AkshareFetcher (Priority 1) - 来自 akshare 库
|
||
3. PytdxFetcher (Priority 2) - 来自 pytdx 库（通达信）
|
||
4. TushareFetcher (Priority 2) - 来自 tushare 库（不可用）
|
||
5. BaostockFetcher (Priority 3) - 来自 baostock 库
|
||
6. YfinanceFetcher (Priority 4) - 来自 yfinance 库
|
||
7. LongbridgeFetcher (Priority 5) - 长桥 OpenAPI（美股/港股兜底）
|
||
|
||
提示：优先级数字越小越优先，同优先级按初始化顺序排列
