🚀 核心功能 +- **容错解析**: 处理各种JSON格式错误，包括语法错误、格式不一致等 +- **多种恢复策略**: 标准JSON解析、手动修复、正则提取、部分解析 +- **Markdown支持**: 自动提取Markdown代码块中的JSON内容 +- **性能优化**: 内置缓存机制，支持高频解析场景 +- **详细统计**: 提供解析统计信息，包括错误率、恢复策略使用情况 + +### 🛠️ 支持的错误类型 +- **无引号键**: `{name: "value"}` → `{"name": "value"}` +- **尾随逗号**: `{"key": "value",}` → `{"key": "value"}` +- **单引号**: `{'key': 'value'}` → `{"key": "value"}` +- **Markdown包裹**: 自动提取
