asp.net Core多环境读取Json

IHostingEnviroment 获取环境相关洗洗

IsDevelopment()、IsStaging()、IsProduction() 分别为:开发、准生产、生产环境

IsEnviroment("Uat") 自定义环境,比如自定义Uat环境

新建:

appsettings.Uat.json文件

{
  "Enviroment": "Uat"
}

Controller文件:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Mvc;
using Microsoft.Extensions.Configuration;

namespace WebApplication1.Controllers
{
    [Route("[Controller]")]
    public class EnviromentController : Controller
    {
        private readonly IConfiguration _configuration;

        public EnviromentController(IConfiguration configuration)
        {
            _configuration = configuration;
        }

        [HttpGet("Index")]
        public IActionResult Index()
        {
            String enviroment=_configuration["Enviroment"];
            return View(nameof(Index), enviroment);
        }
    }
}

view文件:

@model string
@inject Microsoft.AspNetCore.Hosting.IHostingEnvironment hostEnvi
@{
    Layout = null;
}

<!DOCTYPE html>

<html>
<head>
    <meta name="viewport" content="width=device-width" />
    <title>Index</title>
</head>
<body>
    <h1>@hostEnvi.EnvironmentName</h1>
    <h1>@Model</h1>
</body>
</html>

　　在launchSettings.json文件profiles下中添加:

  "Uat": {
      "commandName": "Project",
      "launchBrowser": true,
      "applicationUrl": "http://localhost:5000",
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Uat"
      }
    }

　　选择Uat运行

结果:
