IHostingEnviroment 获取环境相关洗洗
IsDevelopment()、IsStaging()、IsProduction() 分别为:开发、准生产、生产环境

}
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:
