这篇文章主要介绍了详解ASP.NET Core WebApi 返回统一格式参数，长沙网络推广觉得挺不错的，现在分享给大家，也给大家做个参考。一起跟随长沙网络推广过来看看吧
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，比如狼蚁网站SEO优化格式：
{
"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狼蚁SEO。
