亚比谢克的回答是:

如果你想将值导入到静态类中，那么只需使用(ReSharper推荐):

static IConfiguration conf = (JsonConfigurationExtensions.AddJsonFile(new ConfigurationBuilder().SetBasePath(Directory.GetCurrentDirectory()), "appsettings.json").Build());

private static string AuthorizationServiceURL { get; } = conf["ServiceUrls:AuthorizationUrl"];

// appsettings.json
{
  "ServiceUrls": {
    "AuthorizationUrl": "https://example.com/authorize"
  } 
}

就我而言，我从头开始创建所有内容和应用程序设置。Json也没有加载。经过一些调试后，我发现文件从未复制到“目标文件夹”。

为了解决这个问题，我只需要设置正确的文件属性。

它是这样的:

我认为最好的选择是:

创建一个模型类作为配置模式 在DI注册: services.Configure (Configuration.GetSection(“democonfig”)); 从控制器中的DI中获取模型对象的值: private readonly myConfig; (IOptions<your_model> configOps) ｛ 这一点。myConfig = configOps.Value; ｝

这里是一个关于。net框架和Core: web的抽象。Config, app.config和appsettings.json

    static SafeDictionary<string, string> _appSettings;

    public static SafeDictionary<string, string> AppSettings {
        get {
            if (_appSettings == null)
            {
                _appSettings = ConfigurationManager.AppSettings
                    .ToDictionary()
                    .ToSafe();

                BuildAppSettings( JsonAppSettings, "");

            }

            return _appSettings;
        }
    }


    static SafeDictionary<string, string> _connectionStrings;

    public static SafeDictionary<string, string> ConnectionStrings
    {
        get
        {
            if (_connectionStrings == null)
            {
                _connectionStrings = ConfigurationManager.ConnectionStrings
                    .Cast<ConnectionStringSettings>()
                    .ToDictionary(x => x.Name, x => x.ConnectionString)
                    .ToSafe();

                foreach (var jp in JsonAppSettings["ConnectionStrings"].Cast<JProperty>())
                    _connectionStrings.Add(jp.Name, jp.Value.ToString() );

            }

            return _connectionStrings;
        }
    }

我发现用。net Core 3+最容易做到以下几点。我发现所有使用HostBuilders等的其他方法都有点啰嗦，而且可读性不强。这不是专门针对ASP的。但是你可以调整它…

这里有一个工作示例:https://github.com/NotoriousPyro/PyroNexusTradingAlertBot/blob/develop/PyroNexusTradingAlertBot/Program.cs

创建json:

{
"GlobalConfig": {
    "BlacklistedPairs": [ "USD", "USDT", "BUSD", "TUSD", "USDC", "DAI", "USDK" ]
},
"CoinTrackingConfig": {
    "Cookie1": "",
    "Cookie2": "",
    "ApiKey": "",
    "ApiSecret": "",
    "UpdateJobs": [
    {
        "Name": "Binance",
        "Path": "binance_api",
        "JobId": 42202
    },
    {
        "Name": "Bitfinex",
        "Path": "bitfinex_api",
        "JobId": 9708
    }
    ]
},
"DiscordConfig": {
    "BotToken": ""
}
}

创建json对象的类:

class GlobalConfig
{
    public string[] BlacklistedPairs { get; set; }
}
class CoinTrackingConfig
{
    public string Cookie1 { get; set; }
    public string Cookie2 { get; set; }
    public string ApiKey { get; set; }
    public string ApiSecret { get; set; }
    public List<CoinTrackingUpdateJobs> UpdateJobs { get; set; }
}

class CoinTrackingUpdateJobs
{
    public string Name { get; set; }
    public string Path { get; set; }
    public int JobId { get; set; }
}

class DiscordConfig
{
    public string BotToken { get; set; }
}

创建一个helper类:

private class Config
{
    private IConfigurationRoot _configuration;
    public Config(string config) => _configuration = new ConfigurationBuilder()
            .AddJsonFile(config)
            .Build();

    public T Get<T>() where T : new()
    {
        var obj = new T();
        _configuration.GetSection(typeof(T).Name).Bind(obj);
        return obj;
    }
}

服务提供者选项和服务构造函数:

public class DiscordServiceOptions
{
    public string BotToken { get; set; }
}

public DiscordService(IOptions<DiscordServiceOptions> options, ILogger<DiscordService> logger)
{
    _logger = logger;
    _client = new DiscordSocketClient();
    _client.Log += Log;
    _client.Ready += OnReady;
    _client.Disconnected += OnDisconnected;
    _client.LoginAsync(TokenType.Bot, options.Value.BotToken);
    _client.StartAsync();
}

像这样初始化它(将配置传递给服务提供者- IOptions将在服务构建时传递进来):

static async Task Main(string[] args)
{
    var _config = new Config("config.json");

    var globalConfig = config.Get<GlobalConfig>();
    var coinTrackingConfig = config.Get<CoinTrackingConfig>();
    var discordConfig = config.Get<DiscordConfig>();

    _services = new ServiceCollection()
        .AddOptions()
        .Configure<DiscordServiceOptions>(options =>
        {
            options.BotToken = discordConfig.BotToken;
        })
        .AddSingleton<IDiscordService, DiscordService>()
        .AddLogging(logging =>
        {
            logging.SetMinimumLevel(LogLevel.Trace);
            logging.AddNLog(new NLogProviderOptions
            {
                CaptureMessageTemplates = true,
                CaptureMessageProperties = true
            });
        })
        .BuildServiceProvider();
}

我在WPF中遇到了类似的问题。NET Framework 5.0)

我所要做的就是登记。

services.AddSingleton<IConfiguration>(_configuration);

配置本身是这样配置的(在App.xaml.cs中):

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

_configuration = builder.Build();
