Question

在配置文件中，我有

  "HRServices": {
    "CarService": "https://stackoverflow.com/Cars/...",
    "EmployeesService": "https://stackoverflow.com/Employees/...",
    "FinanceService": "https://stackoverflow.com/Finance/...",
    ....
  }

是否可以为所有这些地址指定基本网址？

获得类似

  "baseUrl":"https://stackoverflow.com",
  "HRServices": {
    "CarService": "baseUrl/Cars/...",
    "EmployeesService": "baseUrl/Employees/...",
    "FinanceService": "baseUrl/Finance/...",
    ....
  }

更新：

它在控制器中使用过：

private readonly IConfiguration _configuration;

public HomeController(IConfiguration configuration)
{
    _configuration = configuration;
}

[HttpGet]
public PartialViewResult Index()
{
    string url = _configuration["HRServices:EmployeesService"];
    ...
}


using System.Collections.Generic;

namespace Microsoft.Extensions.Configuration
{
    //
    // Summary:
    //     Represents the root of an Microsoft.Extensions.Configuration.IConfiguration hierarchy.
    public interface IConfigurationRoot : IConfiguration
    {
        //
        // Summary:
        //     The Microsoft.Extensions.Configuration.IConfigurationProviders for this configuration.
        IEnumerable<IConfigurationProvider> Providers { get; }

        //
        // Summary:
        //     Force the configuration values to be reloaded from the underlying Microsoft.Extensions.Configuration.IConfigurationProviders.
        void Reload();
    }
}

没有什么可以自动为您执行此操作，但是您可以手动注册您的强类型配置，然后自己进行：

services.AddScoped(p =>
{
    var config = p.GetRequiredService<IConfiguration>();
    var baseUrl = config["baseUrl"]
    return new HRServicesConfig
    {
        CarService = baseUrl + config["HRServices:CarService"],
        EmployeeService = baseUrl + config["HRServices:EmployeeService"],
        FinanceService = baseUrl + config["HRServices:FinanceService"]
    }
});

一个要注意的是，您将不再使用IOptions，因此您将直接注入HRServicesConfig，而不是类似IOptions<HRServicesConfig>的注入。不过，有些人可能会认为该功能。
