ASP.NET Core WebApi 返回统一参数 详解ASP.NET Core WebApi 返回统一格式参数
田园里的蟋蟀 人气:0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;
});
}
