asp.net core mvc 控制器使用配置

一、在根目录 添加 mysettings.json 文件

mysettings.json 文件代码如下：

{"MySettings": {"Name": "独立配置文件","Site": "lt"}
}

appsettings.json 文件代码如下：

{"Logging": {"LogLevel": {"Default": "Warning"}},"AllowedHosts": "*","WebSettings": {"Name": "涛哥网站","Site": "www.tg.com"}
}

二、core目录下添加相应的类

    public class WebSettings{public string Name { get; set; }public string Site { get; set; }}

    public class MySettings{public string Name { get; set; }public string Site { get; set; }}

 

三、Startup.cs 文件配置

1、将根路径中的JSON配置提供程序添加到生成器

public IConfiguration Configuration { get; set; }
public Startup(IHostingEnvironment env)
{var builder = new ConfigurationBuilder().SetBasePath(env.ContentRootPath) //设置路径为网站根目录.AddJsonFile("appsettings.json", optional: true, reloadOnChange: true).AddJsonFile("mysettings.json", optional: true, reloadOnChange: true);Configuration = builder.Build();
}

2、添加配置类

public void ConfigureServices(IServiceCollection services)
{//添加配置类services.AddOptions();services.Configure<WebSettings>(Configuration.GetSection("WebSettings"));services.Configure<MySettings>(Configuration.GetSection("MySettings"));
}

四、控制器中使用

Microsoft.Extensions.Options

public class HomeController : BaseController
{//通过一个字段来存储private WebSettings webOption;public HomeController(IOptions<WebSettings> weboptions,IOptions<MySettings> myoptions){webOption = weboptions.Value;}
}
