Asp.Net.Core 5 配置文件读取

配置文件如下

{
  "Logging": {
    "LogLevel": {
      "Default": "Information",
      "Microsoft": "Warning",
      "Microsoft.Hosting.Lifetime": "Information"
    }
  },
  "Version": "v1.0",
  "AllowedHosts": "*"
}

 

 

1,构造函数注入IConfiguration

private readonly ILogger<HomeController> _logger;
        private readonly IConfiguration _Configuration;

        public HomeController(ILogger<HomeController> logger,
            IConfiguration configuration
            )
        {
            _logger = logger;
            _Configuration = configuration;
        }

2,读取配置文件信息

  public IActionResult ReadConfig()
        {
            base.ViewBag.Version = _Configuration["Version"];
            base.ViewBag.AllowedHosts = _Configuration["AllowedHosts"];
            base.ViewBag.LoggingDefault = _Configuration["Logging:LogLevel:Default"];
            return View();
        }

 

3,ReadConfig.cshtml 前端显示配置文件 --配置文件信息不给暴露

<h1>配置文件读取</h1>
<div>Version:<b>@ViewBag.Version</b></div>
<div>AllowedHosts:<b>@ViewBag.AllowedHosts</b></div>
<div>Logging-LogLevel-Default:<b>@ViewBag.LoggingDefault</b></div>

显示效果
