c# - 如何将ConfigureServices(IServiceCollection 服务)从.Net 5 迁移到.Net 6？

Question

我正在尝试使用 Azure Active Directory B2C 启用对我自己的 Web api 的身份验证，并按照官方文档提供的步骤进行操作，我需要在我的 startup.cs 中使用此代码，但它是针对 .Net 5 的，我真的不知道如何将其迁移到 .Net 6。你能帮助我吗？

public void ConfigureServices(IServiceCollection services)
{
    // Adds Microsoft Identity platform (Azure AD B2C) support to protect this Api
    services.AddAuthentication(JwtBearerDefaults.AuthenticationScheme)
            .AddMicrosoftIdentityWebApi(options =>
    {
        Configuration.Bind("AzureAdB2C", options);

        options.TokenValidationParameters.NameClaimType = "name";
    },
    options => { Configuration.Bind("AzureAdB2C", options); });
    // End of the Microsoft Identity platform block    

    services.AddControllers();
}

我的Program.cs:

    var builder = WebApplication.CreateBuilder(args);

// Add services to the container.
builder.Services.AddControllersWithViews();

var app = builder.Build();

// Configure the HTTP request pipeline.
if (!app.Environment.IsDevelopment())
{
    app.UseExceptionHandler("/Home/Error");
    // The default HSTS value is 30 days. You may want to change this for production scenarios, see https://aka.ms/aspnetcore-hsts.
    app.UseHsts();
}

app.UseHttpsRedirection();
app.UseStaticFiles();

app.UseRouting();

app.UseAuthentication();
app.UseAuthorization();

app.MapControllerRoute(
    name: "default",
    pattern: "{controller=Home}/{action=Login}/{id?}");

app.Run();

您看到的差异是由于 "top-level statements" feature ，而不一定是 .NET5 与 .NET6。

要添加所需的代码，您可以依赖 builder 对象，它为您提供对服务和配置的访问。

var builder = WebApplication.CreateBuilder(args);

// Add services to the container.
builder.Services.AddControllersWithViews();

// Adds Microsoft Identity platform (Azure AD B2C) support to protect this Api
builder.Services.AddAuthentication(JwtBearerDefaults.AuthenticationScheme)
    .AddMicrosoftIdentityWebApi(options =>
    {
        builder.Configuration.Bind("AzureAdB2C", options);

        options.TokenValidationParameters.NameClaimType = "name";
    },
    options => { Configuration.Bind("AzureAdB2C", options); });
    // End of the Microsoft Identity platform block

var app = builder.Build();

// Configure the HTTP request pipeline.
if (!app.Environment.IsDevelopment())
{
    app.UseExceptionHandler("/Home/Error");
    // The default HSTS value is 30 days. You may want to change this for production scenarios, see https://aka.ms/aspnetcore-hsts.
    app.UseHsts();
}

app.UseHttpsRedirection();
app.UseStaticFiles();

app.UseRouting();

app.UseAuthentication();
app.UseAuthorization();

app.MapControllerRoute(
    name: "default",
    pattern: "{controller=Home}/{action=Login}/{id?}");

app.Run();
