.Net Core读取自定义配置文件

比如有个自定义json配置文件：SettingsBuiltin.json

{  
  "OIDC": {
    "Host": "http://localhost:8020",
    "Https": false,
    "ClientId": "Workspace",
    "ClientSecret": "bf88b9d30eca4f84be20b7744b2b3573",
    "Scopes": [
      "openid",
      "profile",
      "security",
      "org_profile",
      "ad_profile",
      "iam_profile",
      "access_oaplus"
    ],
    "ClaimMaps": [
      {
        "ClaimType": "displayName",
        "JsonKey": "display_name"
      },
      {
        "ClaimType": "nickname",
        "JsonKey": "nickname"
      }
    ]
  }
}

Program.cs

public static IWebHostBuilder CreateWebHostBuilder(string[] args, CancellationTokenSource cancellation) =>
WebHost.CreateDefaultBuilder(args)
.ConfigureAppConfiguration((context, config) =>
{
　　config.AddJsonFile("settings/Builtin.json", false, false);
})
.UseStartup<Startup>();

Startup.cs

public void ConfigureServices(IServiceCollection services)
{
    services.Configure<OpenIdConnectOption>(Configuration.GetSection("OIDC"));

　　　 var provider = services.BuildServiceProvider();

var oidcOption = provider.GetRequiredService<IOptions<OpenIdConnectOption>>().Value;        
}

OpenIdConnectOption 类的结构如下：

    public class OpenIdConnectOption
    {
        public string Host { get; set; }
        public bool Https { get; set; }
        public string ClientId { get; set; }
        public string ClientSecret { get; set; }
        public string[] Scopes { get; set; }
        public ClaimMap[] ClaimMaps { get; set; }
    }

    public class ClaimMap
    {
        public string ClaimType { get; set; }
        public string JsonKey { get; set; }
    }

另外分享一个读取默认配置的工具类

using Microsoft.Extensions.Configuration;
using System.IO;

namespace EIP.Core.DataAccess
{
    public static class AppsettingsConfig
    {
        public static IConfiguration Configuration { get; set; }

        static AppsettingsConfig()
        {
            Configuration = new ConfigurationBuilder()
                   .SetBasePath(Directory.GetCurrentDirectory())
                   .AddJsonFile("appsettings.json", true, reloadOnChange: true).Build();
        }

        public static string GetConfigValue(string key)
        {
            return Configuration[key];
        }
    }
}

使用方法：

var setting = AppsettingsConfig.GetConfigValue("Token:Secret")
