How to get appsettings value in ConfigureAppConfiguration c#

Question

I have to set a configurable value in CreateHostBuilder either from appsettings or any way; I just tried using appsettings

public static IHostBuilder CreateHostBuilder(string[] args) =>
                 Host.CreateDefaultBuilder(args)
                    .ConfigureWebHostDefaults(webBuilder =>
                    {
                        webBuilder.UseStartup<Startup>();
                        webBuilder.ConfigureAppConfiguration((hostingContext, config) =>
                        {
                            var url = _configuration.GetSection("url");
                            config.SetBasePath(hostingContext.HostingEnvironment.ContentRootPath)
                             .AddJsonFile("appsettings.json", optional: true, reloadOnChange: true).AddOcelot(// Set url here)

                               .AddEnvironmentVariables();
                        });

                    });

But url value always returns as null. Does anyone has better solution to get appsetings in ConfigureAppConfiguration or any better idea to use any other idea to set configuration value?

I am wonderig where _configuration from? and what you need url for? — Serge

You can change like below:

public static IHostBuilder CreateHostBuilder(string[] args) =>
Host.CreateDefaultBuilder(args)
    .ConfigureWebHostDefaults(webBuilder =>
    {
        webBuilder.UseStartup<Startup>();
        webBuilder.ConfigureAppConfiguration((hostingContext, config) =>
        {
            var settings = config.Build();
            var url = settings.GetSection("url").Value;

        });

    });

try this

Host.CreateDefaultBuilder(args)
                .ConfigureWebHostDefaults(webBuilder =>
                {
                    webBuilder.UseStartup<Startup>();
                })
             .ConfigureServices((hostContext, services) =>
             {
                 IConfiguration configuration = hostContext.Configuration;
                  var url = configuration.GetSection("url");
             });
