如何在 .NET 6 中将 IApiVersionDescriptionProvider 实现为 Program.cs

Question

我正在使用.NET 6。

我正在为我的 Web API 核心进行版本控制。当我在 Program.cs 中实现 IApiVersionDescriptionProvider 时，我陷入了困境。

因为在创建新项目ASP.NET Core Web API时，只有program.cs文件。（旧的.NET Core有Startup.cs和Program.cs）

请帮助我，谢谢大家这是我的代码

using Microsoft.AspNetCore.Mvc;
using Microsoft.AspNetCore.Mvc.ApiExplorer;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.Options;
using Swashbuckle.AspNetCore.SwaggerGen;
using System.Reflection;
using VfcSolution.Application.User;
using VfcSolution.WebApi;
using VfcSolution.WebApi.VfcSolutionMapper;

var builder = WebApplication.CreateBuilder(args);

// Add services to the container.

builder.Services.AddScoped<IUserRepository, OracleUserRepository>();

builder.Services.AddAutoMapper(typeof(VfcSolutionMappings));

builder.Services.AddApiVersioning(options =>
{
    options.AssumeDefaultVersionWhenUnspecified = true;
    options.DefaultApiVersion = new ApiVersion(1, 0);
    options.ReportApiVersions = true;
});

builder.Services.AddVersionedApiExplorer(options => options.GroupNameFormat = "'v'VVV");

builder.Services.AddTransient<IConfigureOptions<SwaggerGenOptions>, ConfigureSwaggerOptions>();
builder.Services.AddSwaggerGen();

builder.Services.AddControllers();

var app = builder.Build();

// Configure the HTTP request pipeline.

app.UseHttpsRedirection();

if(app.Environment.IsDevelopment())
{
    app.UseDeveloperExceptionPage();
}

app.UseSwagger();

app.UseSwaggerUI(options =>
{   
    ==> I'M STUCKED IN HERE, I DO NOT KNOW HOW TO IMPLEMENT IApiVersionDescriptionProvider
    foreach (var desc in provider.ApiVersionDescriptions)
    {

    }
});

app.UseAuthorization();

app.MapControllers();

app.Run();

您需要在 ; 之后添加以下行builder.Build()：

 using Microsoft.AspNetCore.Mvc.ApiExplorer;

 var app = builder.Build();
 var provider = app.Services.GetRequiredService<IApiVersionDescriptionProvider>();
