传统常规方式统一接口返回值 以及Abp Vnext 统一接口返回值

文章摘要：本文介绍了两种统一API接口返回值的实现方式。传统方式通过定义ResponseModel和ResponseModel<T>基类，包含状态码、消息和数据字段，并提供了扩展方法SetSuccess和SetFail来设置响应结果。ABP框架方式则更全面，通过WrapResult<T>类、WrapResultAttribute特性及ResultExceptionFilter过滤器实现，能自动处理异常并统一返回格式。后者还包含日志记录、状态码转换等功能，通过在控制器或Action上添加WrapResult特性即可启用统一响应格式。两种方式都实现了成功/失败状态的标准化返回，提高了API接口的一致性。
