这篇文章主要介绍了详解ASP.NET Core WebApi 返回统一格式参数，小编觉得挺不错的，现在分享给大家，也给大家做个参考。一起跟随小编过来看看吧
业务场景：
业务需求要求，需要对 WebApi 接口服务统一返回参数，也就是把实际的结果用一定的格式包裹起来，比如下面格式：
{ "response":{ "code":200, "msg":"Remote service error", "result":"" } }
具体实现：
using Microsoft.AspNetCore.Mvc; using Microsoft.AspNetCore.Mvc.Filters; public class WebApiResultMiddleware : ActionFilterAttribute { public override void OnResultExecuting(ResultExecutingContext context) { //根据实际需求进行具体实现 if (context.Result is ObjectResult) { var objectResult = context.Result as ObjectResult; if (objectResult.Value == null) { context.Result = new ObjectResult(new { code = 404, sub_msg = "未找到资源", msg = "" }); } else { context.Result = new ObjectResult(new { code = 200, msg = "", result = objectResult.Value }); } } else if (context.Result is EmptyResult) { context.Result = new ObjectResult(new { code = 404, sub_msg = "未找到资源", msg = "" }); } else if (context.Result is ContentResult) { context.Result = new ObjectResult(new { code = 200, msg = "", result= (context.Result as ContentResult).Content }); } else if (context.Result is StatusCodeResult) { context.Result = new ObjectResult(new { code = (context.Result as StatusCodeResult).StatusCode, sub_msg = "", msg = "" }); } } }
Startup添加对应配置：
public void ConfigureServices(IServiceCollection services) { services.AddMvc(options => { options.Filters.Add(typeof(WebApiResultMiddleware)); options.RespectBrowserAcceptHeader = true; }); }
以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持脚本之家。
