如何从ASP.NET Core中的.json文件中读取AppSettings值

时间:2015-07-16 11:57:12

标签: c# asp.net-core

我在appsettings / Config .json中设置了我的AppSettings数据,如下所示:

{
  "AppSettings": {
        "token": "1234"
    }
}

我在网上搜索过如何从.json文件中读取AppSettings值,但我无法获得任何有用的信息。

我试过了:

var configuration = new Configuration();
var appSettings = configuration.Get("AppSettings"); // null
var token = configuration.Get("token"); // null

我知道在ASP.NET 4.0中你可以这样做:

System.Configuration.ConfigurationManager.AppSettings["token"];

但是我如何在ASP.NET Core中执行此操作?

这有一些曲折。我已将此答案修改为 ASP.NET Core 2.0 (截至26/02/2018)。

这主要来自the official documentation

要在ASP.NET应用程序中使用设置,建议您仅在应用程序的Configuration类中实例化Startup。然后,使用“选项”模式访问各个设置。假设我们有一个appsettings.json文件,如下所示:

{
  "MyConfig": {
   "ApplicationName": "MyApp",
   "Version": "1.0.0"
   }

}

我们有一个代表配置的POCO对象:

public class MyConfig
{
    public string ApplicationName { get; set; }
    public int Version { get; set; }
}

现在我们在Startup.cs

中构建配置
public class Startup 
{
    public IConfigurationRoot Configuration { get; set; }

    public Startup(IHostingEnvironment env)
    {
        var builder = new ConfigurationBuilder()
            .SetBasePath(env.ContentRootPath)
            .AddJsonFile("appsettings.json", optional: true, reloadOnChange: true);

        Configuration = builder.Build();
    }
}

请注意,{Core} 2.0中appsettings.json默认 。如果需要,我们还可以为每个环境注册一个appsettings.{Environment}.json配置文件。

如果我们想将配置注入控制器,我们需要在运行时注册它。我们是通过Startup.ConfigureServices

这样做的
public void ConfigureServices(IServiceCollection services)
{
    services.AddMvc();

    // Add functionality to inject IOptions<T>
    services.AddOptions();

    // Add our Config object so it can be injected
    services.Configure<MyConfig>(Configuration.GetSection("MyConfig"));
}

我们这样注入:

public class HomeController : Controller
{
    private readonly IOptions<MyConfig> config;

    public HomeController(IOptions<MyConfig> config)
    {
        this.config = config;
    }

    // GET: /<controller>/
    public IActionResult Index() => View(config.Value);
}

完整的Startup课程:

public class Startup 
{
    public IConfigurationRoot Configuration { get; set; }

    public Startup(IHostingEnvironment env)
    {
        var builder = new ConfigurationBuilder()
            .SetBasePath(env.ContentRootPath)
            .AddJsonFile("appsettings.json", optional: true, reloadOnChange: true);

        Configuration = builder.Build();
    }

    public void ConfigureServices(IServiceCollection services)
    {
        services.AddMvc();

        // Add functionality to inject IOptions<T>
        services.AddOptions();

        // Add our Config object so it can be injected
        services.Configure<MyConfig>(Configuration.GetSection("MyConfig"));
    }
}

首先: Microsoft.Framework.ConfigurationModel的程序集名称和命名空间已更改为Microsoft.Framework.Configuration。所以你应该使用: e.g。

"Microsoft.Framework.Configuration.Json": "1.0.0-beta7"

作为project.json中的依赖项。如果您没有安装7,请使用beta5或6。 然后你可以在Startup.cs中执行类似的操作。

public IConfiguration Configuration { get; set; }

public Startup(IHostingEnvironment env, IApplicationEnvironment appEnv)
{
     var configurationBuilder = new ConfigurationBuilder(appEnv.ApplicationBasePath)
        .AddJsonFile("config.json")
        .AddEnvironmentVariables();
     Configuration = configurationBuilder.Build();
}

如果您想从config.json中检索变量,可以使用以下命令立即获取:

public void Configure(IApplicationBuilder app)
    {
        // Add .Value to get the token string
        var token = Configuration.GetSection("AppSettings:token");
        app.Run(async (context) =>
        {
            await context.Response.WriteAsync("This is a token with key (" + token.Key + ") " + token.Value);
        });
    }

或者您可以创建一个名为AppSettings的类:

public class AppSettings
{
    public string token { get; set; }
}

并配置如下服务:

public void ConfigureServices(IServiceCollection services)
{       
    services.AddMvc();

    services.Configure<MvcOptions>(options =>
    {
        //mvc options
    });

    services.Configure<AppSettings>(Configuration.GetSection("AppSettings"));
}

然后通过例如访问它像这样的控制器:

public class HomeController : Controller
{
    private string _token;

    public HomeController(IOptions<AppSettings> settings)
    {
        _token = settings.Options.token;
    }
}

答案 2 :(得分:33)

对于.NET Core 2.0,情况有所改变。启动构造函数将Configuration对象作为参数,因此不需要使用ConfigurationBuilder。这是我的:

public Startup(IConfiguration configuration)
{
    Configuration = configuration;
}

public IConfiguration Configuration { get; }

// This method gets called by the runtime. Use this method to add services to the container.
public void ConfigureServices(IServiceCollection services)
{
    services.Configure<StorageOptions>(Configuration.GetSection("AzureStorageConfig"));
}

我的POCO是顶部提到的StorageOptions对象:

namespace Brazzers.Models
{
    public class StorageOptions
    {
        public String StorageConnectionString { get; set; }
        public String AccountName { get; set; }
        public String AccountKey { get; set; }
        public String DefaultEndpointsProtocol { get; set; }
        public String EndpointSuffix { get; set; }

        public StorageOptions() { }
    }
}

配置实际上是我的appsettings.json文件的一个子部分,名为AzureStorageConfig

{
  "ConnectionStrings": {
    "DefaultConnection": "Server=(localdb)\\mssqllocaldb;",
    "StorageConnectionString": "DefaultEndpointsProtocol=https;AccountName=brazzerswebapp;AccountKey=Cng4Afwlk242-23=-_d2ksa69*2xM0jLUUxoAw==;EndpointSuffix=core.windows.net"
  },
  "Logging": {
    "IncludeScopes": false,
    "LogLevel": {
      "Default": "Warning"
    }
  },

  "AzureStorageConfig": {
    "AccountName": "brazzerswebapp",
    "AccountKey": "Cng4Afwlk242-23=-_d2ksa69*2xM0jLUUxoAw==",
    "DefaultEndpointsProtocol": "https",
    "EndpointSuffix": "core.windows.net",
    "StorageConnectionString": "DefaultEndpointsProtocol=https;AccountName=brazzerswebapp;AccountKey=Cng4Afwlk242-23=-_d2ksa69*2xM0jLUUxoAw==;EndpointSuffix=core.windows.net"
  }
}

我唯一要补充的是,由于构造函数已经更改,我还没有测试是否需要为加载appsettings.<environmentname>.json而不是appsettings.json加载额外的东西。< / p>

对于ASP.NET Core 3.1,您可以遵循以下文档:

https://docs.microsoft.com/en-us/aspnet/core/fundamentals/configuration/?view=aspnetcore-3.1

在创建新的ASP.NET Core 3.1项目时,您将在Program.cs中具有以下配置行:

Host.CreateDefaultBuilder(args)

这将启用以下功能:

  1. ChainedConfigurationProvider:将现有的IConfiguration添加为 资源。在默认配置情况下,添加主机 配置并将其设置为应用程序的第一个来源 组态。
  2. appsettings.json使用JSON配置 提供者。
  3. appsettings.Environment.json使用JSON配置 提供者。例如,appsettings.Production.json和 appsettings.Development.json。
  4. 当应用程序在 开发环境。
  5. 使用环境的环境变量 变量配置提供程序。
  6. 使用 命令行配置提供程序。

这意味着您可以注入IConfiguration并使用字符串键获取值,甚至是嵌套值。像IConfiguration ["Parent:Child"];

示例:

appsettings.json

{
  "ApplicationInsights":
    {
        "Instrumentationkey":"putrealikeyhere"
    }
}

WeatherForecast.cs

[ApiController]
[Route("[controller]")]
public class WeatherForecastController : ControllerBase
{
    private static readonly string[] Summaries = new[]
    {
        "Freezing", "Bracing", "Chilly", "Cool", "Mild", "Warm", "Balmy", "Hot", "Sweltering", "Scorching"
    };

    private readonly ILogger<WeatherForecastController> _logger;
    private readonly IConfiguration _configuration;

    public WeatherForecastController(ILogger<WeatherForecastController> logger, IConfiguration configuration)
    {
        _logger = logger;
        _configuration = configuration;
    }

    [HttpGet]
    public IEnumerable<WeatherForecast> Get()
    {
        var key = _configuration["ApplicationInsights:InstrumentationKey"];

        var rng = new Random();
        return Enumerable.Range(1, 5).Select(index => new WeatherForecast
        {
            Date = DateTime.Now.AddDays(index),
            TemperatureC = rng.Next(-20, 55),
            Summary = Summaries[rng.Next(Summaries.Length)]
        })
        .ToArray();
    }
}

{
  "AppConfig": {
    "FilePath": "C:\\temp\\logs\\output.txt"
  }
}

4- Program.cs

configurationSection.KeyconfigurationSection.Value将具有配置属性。

static void Main(string[] args)
{
    try
    {

        IConfigurationBuilder builder = new ConfigurationBuilder()
            .SetBasePath(Directory.GetCurrentDirectory())
            .AddJsonFile("appsettings.json", optional: true, reloadOnChange: true);

        IConfigurationRoot configuration = builder.Build();
        // configurationSection.Key => FilePath
        // configurationSection.Value => C:\\temp\\logs\\output.txt
        IConfigurationSection configurationSection = configuration.GetSection("AppConfig").GetSection("FilePath");  

    }

只是为了补充Yuval Itzchakov的答案。

您可以在不使用构建器功能的情况下加载配置,只需注入它即可。

public IConfiguration Configuration { get; set; }

public Startup(IConfiguration configuration)
{
   Configuration = configuration;
}

对于.NET Core 2.0,您只需:

在appsettings.json中声明您的键/值对:

{
  "MyKey": "MyValue"
}

将配置服务注入startup.cs,并使用该服务获取值

using Microsoft.Extensions.Configuration;

public class Startup
{
    public void Configure(IConfiguration configuration,
                          ... other injected services
                          )
    {
        app.Run(async (context) =>
        {
            string myValue = configuration["MyKey"];
            await context.Response.WriteAsync(myValue);
        });

除了现有的答案外,我还想提一下,为简单起见,有时为IConfiguration使用扩展方法可能会有用。

我将JWT配置保留在appsettings.json中,因此我的扩展方法类如下所示:

public static class ConfigurationExtensions
{
    public static string GetIssuerSigningKey(this IConfiguration configuration)
    {
        string result = configuration.GetValue<string>("Authentication:JwtBearer:SecurityKey");
        return result;
    }

    public static string GetValidIssuer(this IConfiguration configuration)
    {
        string result = configuration.GetValue<string>("Authentication:JwtBearer:Issuer");
        return result;
    }

    public static string GetValidAudience(this IConfiguration configuration)
    {
        string result = configuration.GetValue<string>("Authentication:JwtBearer:Audience");
        return result;
    }

    public static string GetDefaultPolicy(this IConfiguration configuration)
    {
        string result = configuration.GetValue<string>("Policies:Default");
        return result;
    }

    public static SymmetricSecurityKey GetSymmetricSecurityKey(this IConfiguration configuration)
    {
        var issuerSigningKey = configuration.GetIssuerSigningKey();
        var data = Encoding.UTF8.GetBytes(issuerSigningKey);
        var result = new SymmetricSecurityKey(data);
        return result;
    }

    public static string[] GetCorsOrigins(this IConfiguration configuration)
    {
        string[] result =
            configuration.GetValue<string>("App:CorsOrigins")
            .Split(",", StringSplitOptions.RemoveEmptyEntries)
            .ToArray();

        return result;
    }
}

它节省了很多行,而您只编写了简洁的代码:

...
x.TokenValidationParameters = new TokenValidationParameters()
{
    ValidateIssuerSigningKey = true,
    ValidateLifetime = true,
    IssuerSigningKey = _configuration.GetSymmetricSecurityKey(),
    ValidAudience = _configuration.GetValidAudience(),
    ValidIssuer = _configuration.GetValidIssuer()
};

也可以将IConfiguration实例注册为单例并将其注入到您需要的任何地方-我使用Autofac容器,方法如下:

var appConfiguration = AppConfigurations.Get(WebContentDirectoryFinder.CalculateContentRootFolder());
builder.Register(c => appConfiguration).As<IConfigurationRoot>().SingleInstance();

您可以对MS Dependency Injection做同样的事情:

services.AddSingleton<IConfigurationRoot>(appConfiguration);

        {
            _HttpContextAccessor = httpContextAccessor;
        }
        public static void Configure(IHttpContextAccessor httpContextAccessor)
        {
            _HttpContextAccessor = httpContextAccessor;
        }
        public static IConfigurationBuilder Getbuilder()
        {
            var builder = new ConfigurationBuilder()
              .SetBasePath(Directory.GetCurrentDirectory())
              .AddJsonFile("appsettings.json");
            return builder;
        }

        public static string GetAppSetting(string key)
        {
            //return Convert.ToString(ConfigurationManager.AppSettings[key]);
            var builder = Getbuilder();
            var GetAppStringData = builder.Build().GetValue<string>("AppSettings:" + key);
            return GetAppStringData;
        }

        public static string GetConnectionString(string key="DefaultName")
        {
            var builder = Getbuilder();
            var ConnectionString = builder.Build().GetValue<string>("ConnectionStrings:"+key);
            return ConnectionString;
        }
    }

在这里我创建了一个类来获取连接字符串和应用程序设置。

.NET Core 2.2方式

(毫无疑问,Microsoft将在下一个.NET版本中再次将其更改为完全不同的内容。)

1。 appSettings.json

它可能看起来像这样。在这里,我们将加载Setting1和Setting2

{
  "Logging": {
    "LogLevel": {
      "Default": "Warning"
    }
  },
  "AllowedHosts": "*",
  "Setting1": "abc",
  "Setting2": 123
}

2。 AppSettings.cs

用于保存Setting1和Setting2的POCO类。我们将把appsettings.json加载到该类对象中。 POCO类的结构应与JSON文件匹配,如果需要,属性可以嵌套在其他属性/类中。

public class AppSettings
{
    public string Setting1 { get; set; }
    public int Setting2 { get; set; }
}

3 Startup.cs

将appSettings.json加载到您的AppSettings对象中并开始使用它:

public class Startup
{
    public Startup(IConfiguration configuration)
    {
        AppSettings settings = new AppSettings();

        Configuration = configuration;
        configuration.Bind(settings);

        // Now start using it

通过调用Get<YourType>()将其作为对象放入控制器内部

public IActionResult Index([FromServices] IConfiguration config) { BillModel model= config.GetSection("Yst.Requisites").Get<BillModel>(); return View(model); }

使用netcoreapp 3.1的最新版本,您可以非常简单地进行此操作,而无需任何第三方依赖性。

created a gist for this,但是您可以使用此类读取JSON文件并返回动态属性。

using System.Text.Json;
using System.IO;

class ConfigurationLoader
{

    private dynamic configJsonData;
    public ConfigurationLoader Load(string configFilePath = "appsettings.json")
    {
        var appSettings = File.ReadAllText(configFilePath);
        this.configJsonData = JsonSerializer.Deserialize(appSettings, typeof(object));
        return this;
    }

    public dynamic GetProperty(string key)
    {
        var properties = key.Split(".");
        dynamic property = this.configJsonData;
        foreach (var prop in properties)
        {
            property = property.GetProperty(prop);
        }

        return property;
    }
}

我专门做了这个,所以我可以在我的dotnet控制台应用程序中使用appconfig.json。我只是将其放在我的Program.Main函数中:

var config = new ConfigurationLoader();
config.Load();
Console.WriteLine(config.GetProperty("Environment.Name"));

这将返回该属性的dynamic对象。 (如果不是基本类型,则为JsonElement)。 我的appsettings.json文件如下所示:

{
  "Environment": {
    "Token": "abc-123",
    "Name": "Production"
  }
}
