市场有风险,投资需谨慎
v1.1.0 修复说明
修复新股过滤bug:原代码错误地检查股票代码(
code)是否以C/N开头,实际股票代码为纯数字,新股标识在名称(name)中。已修正为检查stock.name。优化Vercel超时:默认候选数从300降至80,避免Vercel免费版(10秒超时)扫描超时。可通过
maxCandidates参数调整(范围20-200)。添加API重试机制:所有东方财富API调用增加2次重试+超时控制,提升网络不稳定时的成功率。
更新vercel.json:使用现代
rewrites配置替代已废弃的builds/routes语法。添加MCP协议头:响应增加
MCP-Protocol-Version头,提升与MCP客户端的兼容性。优化导入:
market_overview工具改用静态导入,去除不必要的动态import。
重要提示
Vercel免费版超时限制:单次扫描需在10秒内完成。默认80只候选股约需4-8秒。若市场数据量大或API响应慢可能超时。如需扫描更多股票,建议升级Vercel Pro(60秒超时)或自行部署到其他平台。
东方财富API可用性:该API为非官方公开接口,可能随时变更或限制IP。若部署后持续返回错误,需考虑更换数据源。
交易时段:建议在交易时段(9:30-15:00)使用,非交易时段数据为上一交易日收盘数据。
