在.NetCore中实现密钥库，并将值转换为Startup.cs .NetCore应用程序中的模型

public class KeyVault
{
    private Dictionary<string, string> _keyValuePairs;

    public KeyVault()
    {
        _keyValuePairs = new Dictionary<string, string>();
    }

    public void AddKey(string key, string value)
    {
        _keyValuePairs[key] = value;
    }

    public string GetValue(string key)
    {
        if (_keyValuePairs.ContainsKey(key))
        {
            return _keyValuePairs[key];
        }
        return null;
    }
}

public class Startup
{
    private readonly KeyVault _keyVault;

    public Startup(IConfiguration configuration)
    {
        _keyVault = new KeyVault();
        // 添加密钥和值到密钥库
        _keyVault.AddKey("Key1", "Value1");
        _keyVault.AddKey("Key2", "Value2");
        // 可以从其他配置源中读取密钥和值，并添加到密钥库中
        // ...
    }

    public void ConfigureServices(IServiceCollection services)
    {
        // 注册KeyVault实例为服务
        services.AddSingleton(_keyVault);

        // 其他服务的注册
        // ...
    }

    public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
    {
        // 获取密钥库中的值，并转换为AppSettings模型
        var appSettings = new AppSettings
        {
            Key1 = _keyVault.GetValue("Key1"),
            Key2 = _keyVault.GetValue("Key2")
        };

        // 其他配置和中间件的设置
        // ...
    }
}
