這篇文章主要介紹了詳解ASP.NET Core WebApi 返回統(tǒng)一格式參數(shù)，小編覺得挺不錯的，現(xiàn)在分享給大家，也給大家做個參考。一起跟隨小編過來看看吧

業(yè)務場景：

業(yè)務需求要求，需要對 WebApi 接口服務統(tǒng)一返回參數(shù)，也就是把實際的結(jié)果用一定的格式包裹起來，比如下面格式：

{
  "response":{
    "code":200,
    "msg":"Remote service error",
    "result":""
  }
}

具體實現(xiàn)：

using Microsoft.AspNetCore.Mvc;
using Microsoft.AspNetCore.Mvc.Filters;

public class WebApiResultMiddleware : ActionFilterAttribute
{
  public override void OnResultExecuting(ResultExecutingContext context)
  {
    //根據(jù)實際需求進行具體實現(xiàn)
    if (context.Result is ObjectResult)
    {
      var objectResult = context.Result as ObjectResult;
      if (objectResult.Value == null)
      {
        context.Result = new ObjectResult(new { code = 404, sub_msg = "未找到資源", 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 = "未找到資源", 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添加對應配置：

public void ConfigureServices(IServiceCollection services)
{
  services.AddMvc(options =>
  {
    options.Filters.Add(typeof(WebApiResultMiddleware));
    options.RespectBrowserAcceptHeader = true;
  });
}
