使用.Net核心的OAuth实现2.0，Swagger

dotnet add package Microsoft.AspNetCore.Authentication.JwtBearer
dotnet add package Swashbuckle.AspNetCore

public void ConfigureServices(IServiceCollection services)
{
    services.AddAuthentication(options =>
    {
        options.DefaultAuthenticateScheme = JwtBearerDefaults.AuthenticationScheme;
        options.DefaultChallengeScheme = "OAuth2";
    })
    .AddJwtBearer(options =>
    {
        options.TokenValidationParameters = new TokenValidationParameters
        {
            ValidateIssuer = true,
            ValidateAudience = true,
            ValidateLifetime = true,
            ValidateIssuerSigningKey = true,
            ValidIssuer = Configuration["Jwt:Issuer"],
            ValidAudience = Configuration["Jwt:Audience"],
            IssuerSigningKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes(Configuration["Jwt:SecretKey"]))
        };
    })
    .AddOAuth("OAuth2", options =>
    {
        options.ClientId = Configuration["OAuth2:ClientId"];
        options.ClientSecret = Configuration["OAuth2:ClientSecret"];
        options.AuthorizationEndpoint = "https://authorization-server.com/oauth/authorize";
        options.TokenEndpoint = "https://authorization-server.com/oauth/token";
        options.UserInformationEndpoint = "https://authorization-server.com/userinfo";

        options.CallbackPath = new PathString("/signin-oauth2");
        options.SaveTokens = true;
    });

    services.AddControllers();
    services.AddSwaggerGen(c =>
    {
        c.SwaggerDoc("v1", new OpenApiInfo { Title = "My API", Version = "v1" });
    });
}

public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
    if (env.IsDevelopment())
    {
        app.UseDeveloperExceptionPage();
        app.UseSwagger();
        app.UseSwaggerUI(c => c.SwaggerEndpoint("/swagger/v1/swagger.json", "My API V1"));
    }

    app.UseRouting();

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

    app.UseEndpoints(endpoints =>
    {
        endpoints.MapControllers();
    });
}
