c# - 为使用 IdentityServer4 进行身份验证的 Asp Net Core API 构建集成测试

Question

我构建了一个简单的 AspNetCore 2.2 API，它使用 IdentityServer 4 来处理 OAuth。它工作正常，但我现在想添加集成测试，最近发现 this 。我用它构建了一些测试，这些测试都运行良好 - 只要我的 Controller 上没有 [Authorize] 属性 - 但显然该属性需要存在。

我遇到了this stackoverflow question根据那里给出的答案，我尝试将测试放在一起，但当我尝试运行测试时，我仍然收到 Unauthorized 响应。

请注意:我真的不知道在创建客户端时应该使用哪些详细信息。

• 允许的范围应该是什么？ (它们应该与真实的相符吗？范围)

构建 IdentityServerWebHostBuilder 时也是如此

• 我应该将什么传递给 .AddApiResources？ (也许是个愚蠢的问题，但是这有关系吗)

如果有人能指导我，我将不胜感激。

这是我的测试:

[Fact]
public async Task Attempt_To_Test_InMemory_IdentityServer()
{
    // Create a client
        var clientConfiguration = new ClientConfiguration("MyClient", "MySecret");

        var client = new Client
        {
            ClientId = clientConfiguration.Id,
            ClientSecrets = new List<Secret>
            {
                new Secret(clientConfiguration.Secret.Sha256())
            },
            AllowedScopes = new[] { "api1" },
            AllowedGrantTypes = new[] { GrantType.ClientCredentials },
            AccessTokenType = AccessTokenType.Jwt,
            AllowOfflineAccess = true
        };

        var webHostBuilder = new IdentityServerWebHostBuilder()
            .AddClients(client)
            .AddApiResources(new ApiResource("api1", "api1name"))
            .CreateWebHostBuilder();

        var identityServerProxy = new IdentityServerProxy(webHostBuilder);
        var tokenResponse = await identityServerProxy.GetClientAccessTokenAsync(clientConfiguration, "api1");

        // *****
        // Note: creating an IdentityServerProxy above in order to get an access token
        // causes the next line to throw an exception stating: WebHostBuilder allows creation only of a single instance of WebHost
        // *****

        // Create an auth server from the IdentityServerWebHostBuilder 
        HttpMessageHandler handler;
        try
        {
            var fakeAuthServer = new TestServer(webHostBuilder);
            handler = fakeAuthServer.CreateHandler();
        }
        catch (Exception e)
        {
            throw;
        }

        // Create an auth server from the IdentityServerWebHostBuilder 
        HttpMessageHandler handler;
        try
        {
            var fakeAuthServer = new TestServer(webHostBuilder);
            handler = fakeAuthServer.CreateHandler();
        }
        catch (Exception e)
        {
            Console.WriteLine(e);
            throw;
        }

        // Set the BackChannelHandler of the 'production' IdentityServer to use the 
        // handler form the fakeAuthServer
        Startup.BackChannelHandler = handler;
        // Create the apiServer
        var apiServer = new TestServer(new WebHostBuilder().UseStartup<Startup>());
        var apiClient = apiServer.CreateClient();


        apiClient.SetBearerToken(tokenResponse.AccessToken);

        var user = new User
        {
            Username = "<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="6b18020604050704060a132b0e000645080406" rel="noreferrer noopener nofollow">[email protected]</a>",
            Password = "Password-123"
        };

        var req = new HttpRequestMessage(new HttpMethod("GET"), "/api/users/login")
        {
            Content = new StringContent(JsonConvert.SerializeObject(user), Encoding.UTF8, "application/json"),
        };

        // Act
        var response = await apiClient.SendAsync(req);

        // Assert
        Assert.Equal(HttpStatusCode.OK, response.StatusCode);

}

我的启动类(class):

public class Startup
{

    public IConfiguration Configuration { get; }
    public static HttpMessageHandler BackChannelHandler { get; set; }

    public Startup(IConfiguration configuration)
    {
        Configuration = configuration;
    }

    // This method gets called by the runtime. Use this method to add services to the container.
    public void ConfigureServices(IServiceCollection services)
    {
        services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1);
        ConfigureAuth(services);    
        services.AddTransient<IPassportService, PassportService>();
        services.Configure<ApiBehaviorOptions>(options =>
        {
            options.SuppressModelStateInvalidFilter = true;
        });

    }

    protected virtual void ConfigureAuth(IServiceCollection services)
    {
        services.AddAuthentication(JwtBearerDefaults.AuthenticationScheme)
            .AddJwtBearer(options =>
            {
                options.Authority = Configuration.GetValue<string>("IdentityServerAuthority");
                options.Audience = Configuration.GetValue<string>("IdentityServerAudience");
                options.BackchannelHttpHandler = BackChannelHandler;
            });
    }


    // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
    public void Configure(IApplicationBuilder app, IHostingEnvironment env)
    {
        if (env.IsDevelopment())
        {
            app.UseDeveloperExceptionPage();
        }
        else
        {
            app.UseHsts();
        }

        app.UseAuthentication();
        app.UseHttpsRedirection();
        app.UseMvc();
        app.UseExceptionMiddleware();
    }
}

编辑:

下面的建议是一个问题。由于尝试构建 WebHostBuilder 时出现异常，原始源代码失败 twice 。其次，配置文件仅存在于 API 项目中，而不存在于测试项目中，这就是权限未设置的原因。

而不是这样做

services.AddAuthentication(JwtBearerDefaults.AuthenticationScheme)
   .AddJwtBearer(options =>
   {
       options.Authority = Configuration.GetValue<string>("IdentityServerAuthority");
       options.Audience = Configuration.GetValue<string>("IdentityServerAudience");
       options.BackchannelHttpHandler = BackChannelHandler;
   });

你必须做这样的事情:

services.AddAuthentication(JwtBearerDefaults.AuthenticationScheme)
   .AddIdentityServerAuthentication(options =>
   {
      options.Authority = Configuration.GetValue<string>("IdentityServerAuthority");
      options.JwtBackChannelHandler = BackChannelHandler;
    });

您可以找到示例here .

希望有帮助，对我有用!
