如何将ASP 5/Core Web API与[授权]属性集成测试

Question

我目前有一个ASP 5/ASP核心Web API,我需要与OWIN测试服务器进行集成测试.

问题是我在生产中使用IdentityServer作为授权服务器,我不想将授权作为集成测试的一部分.

这是API的Startup.cs:

public Startup(IHostingEnvironment env)
{
    // Set up configuration sources.
    IConfigurationBuilder builder = new ConfigurationBuilder()
        .AddJsonFile("appsettings.json")
        .AddJsonFile($"appsettings.{env.EnvironmentName}.json", true);

    if (env.IsEnvironment("Development"))
    {
        // This will push telemetry data through Application Insights pipeline faster, allowing you to view results immediately.
        builder.AddApplicationInsightsSettings(developerMode: true);
    }

    builder.AddEnvironmentVariables();
    Configuration = builder.Build().ReloadOnChanged("appsettings.json");
}

public IConfigurationRoot Configuration { get; set; }

// This method gets called by the runtime. Use this method to add services to the container
public IServiceProvider ConfigureServices(IServiceCollection services)
{
    // Add framework services.
    services.AddApplicationInsightsTelemetry(Configuration);

    ConfigureEntityFrameworkDatabase(services, Configuration);

    services.AddIdentity<IdentityUser, IdentityRole>()
        .AddEntityFrameworkStores<HoehenSuchtIdentityDbContext>()
        .AddDefaultTokenProviders();

    ConfigureMvc(services);

    // register autofac as dependency resolver
    ContainerBuilder containerBuilder = new ContainerBuilder();

    // register all required autofac modules
    RegisterAutofacModules(containerBuilder);

    // register all automapper mappings as di services so there dependencies can be resolved
    ConfigureAutomapper(containerBuilder);

    ConfigureSwagger(services);

    // copy all asp core dependency injection registrations to autofac
    containerBuilder.Populate(services);
    IContainer container = containerBuilder.Build();

    return container.Resolve<IServiceProvider>();
}

// This method gets called by the runtime. Use this method to configure the HTTP request pipeline

public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
{
    loggerFactory.AddConsole(Configuration.GetSection("Logging"));
    loggerFactory.AddDebug();

    if (env.IsDevelopment())
    {
        app.UseBrowserLink();
        app.UseDeveloperExceptionPage();
        app.UseDatabaseErrorPage();
    }

    // make sure the database was created and all migrations applied
    MigrateDatabase(app);
    app.ApplicationServices.GetService<HoehenSuchtDbContext>().EnsureSeedData(env);

    app.UseIISPlatformHandler();

    app.UseApplicationInsightsRequestTelemetry();
    app.UseApplicationInsightsExceptionTelemetry();

    ConfigureIdentityServer(app, Configuration);

    app.UseStaticFiles();

    app.UseMvc();

    //app.UseSwaggerGen(/*routeTemplate: "docs/{apiVersion}/swagger.json"*/);
    //app.UseSwaggerUi(/*baseRoute: "docs", swaggerUrl: "docs/v1/swagger.json"*/);
}

public static Action<IServiceCollection, IConfigurationRoot> ConfigureEntityFrameworkDatabase = (services, config) =>
{
    services.AddEntityFramework()
        .AddSqlServer()
        .AddDbContext<HoehenSuchtDbContext>(builder =>
            builder.UseSqlServer(config["Data:DefaultConnection:ConnectionString"]))
        .AddDbContext<HoehenSuchtIdentityDbContext>(builder =>
            builder.UseSqlServer(config["Data:IdentityConnection:ConnectionString"]));
};

public static Action<IServiceCollection> ConfigureMvc = services =>
{
    services.AddMvc().AddControllersAsServices(new List<Assembly> { typeof(Startup).GetTypeInfo().Assembly });
};

我已经尝试注册一个特殊的测试中间件,理论上应该验证并设置索赔主体.但在OWIN管道的某处,身份验证被拒绝,我收到401错误代码.

这就是我设置OWIN测试服务器的方法:

Startup.MigrateDatabase = app =>
{
    app.ApplicationServices.GetService<HoehenSuchtDbContext>().Database.EnsureCreated();
};
Startup.ConfigureEntityFrameworkDatabase = ApiTestServer.ConfigureInMemoryDatabase;
Startup.ConfigureIdentityServer = (app, config) =>
{
    app.ApplicationServices.GetService<HoehenSuchtDbContext>().EnsureSeedData(new HostingEnvironment {EnvironmentName = "development" });

    app.UseMiddleware<AuthenticatedTestRequestMiddleware>();
};
Server = new TestServer(TestServer.CreateBuilder().UseStartup<Startup>());

这是我的习惯AuthenticatedTestRequestMiddleware:

public class AuthenticatedTestRequestMiddleware
{
    public const string TestingCookieAuthentication = "TestCookieAuthentication";
    public const string TestingHeader = "X-Integration-Testing";
    public const string TestingHeaderValue = "78EAAA45-E68B-43C7-9D12-3A5F1E646BD5";

    private readonly RequestDelegate _next;

    public AuthenticatedTestRequestMiddleware(RequestDelegate next)
    {
        _next = next;
    }

    public async Task Invoke(HttpContext context)
    {
        if (context.Request.Headers.Keys.Contains(TestingHeader) && context.Request.Headers[TestingHeader].First().Equals(TestingHeaderValue))
        {
            // fake authenticated the user
            ClaimsIdentity claimsIdentity = new ClaimsIdentity();
            claimsIdentity.AddClaims(new List<Claim>
            {
                new Claim(ClaimTypes.Name, "admin"),
                new Claim(ClaimTypes.NameIdentifier, UserSeedData.AdminUserId)
            });
            ClaimsPrincipal claimsPrincipal = new ClaimsPrincipal(claimsIdentity);
            context.User = claimsPrincipal;
        }

        await _next(context);
    }
}

主体已设置并存在于具有给定ID的数据库中,但在我调用后,next(context)我得到一个401 Unauthorized结果.

如何成功假冒用户身份并绕过[授权],同时还为HttpRequest设置当前用户？

更新: 如果我注册我自己的CookieAuthentication处理程序:

app.UseCookieAuthentication(options =>
{
    options.AuthenticationScheme = AuthenticatedTestRequestMiddleware.TestingCookieAuthentication;
    options.AutomaticAuthenticate = true;
    options.AutomaticChallenge = true;
});

我进入302 Redirect登录页面.然而,当我在TestMiddleware中使用它时,登录正常工作await context.Authentication.SignInAsync(TestingCookieAuthentication, claimsPrincipal)

Answer 1

好的,所以我发现了为什么它不起作用:)

创建ClaimsPrincipalAuthenticationProvider时必须包含在主体的构造函数中.如果未提供身份验证类型,则该SignInAsync()功能将失败并且不会对用户进行身份验证.

而不是这样做:

ClaimsIdentity claimsIdentity = new ClaimsIdentity(new List<Claim>
{
    new Claim(ClaimTypes.Name, "admin"),
    new Claim(ClaimTypes.NameIdentifier, UserSeedData.AdminUserId)
});

您必须像这样指定AuthenticationHandler:

ClaimsIdentity claimsIdentity = new ClaimsIdentity(new List<Claim>
{
    new Claim(ClaimTypes.Name, "admin"),
    new Claim(ClaimTypes.NameIdentifier, UserSeedData.AdminUserId)
}, TestingCookieAuthentication);
