private const string AzureAdConfigKey = "AzureAd";
private const string OAuth2Definition = "openid";
private IConfiguration Configuration get;
private IHostingEnvironment Environment get;
public Startup(IConfiguration configuration, IHostingEnvironment environment)
Environment = environment;
Configuration = configuration;
public void ConfigureServices(IServiceCollection services)
services.AddAuthentication(AzureADDefaults.JwtBearerAuthenticationScheme)
.AddAzureADBearer(options => Configuration.Bind(AzureAdConfigKey, options));
services.Configure<JwtBearerOptions>(AzureADDefaults.JwtBearerAuthenticationScheme,
options => options.Authority += "/v2.0");
var authorizationPolicy = new AuthorizationPolicyBuilder()
.RequireAuthenticatedUser()
.Build();
services.AddMvc(options => options.Filters.Add(new AuthorizeFilter(authorizationPolicy)))
.SetCompatibilityVersion(CompatibilityVersion.Version_2_2);
var azureAdAuthority = $"https://login.microsoftonline.com/Configuration["AzureAd:TenantId"]/oauth2/v2.0";
services.AddSwaggerGen(options =>
options.SwaggerDoc("v1", new Info
Title = "My Api Name",
Version = "v1"
);
options.AddSecurityDefinition(OAuth2Definition, new OAuth2Scheme
Description = "OAuth2 Implicit Grant",
Flow = "implicit",
AuthorizationUrl = $"azureAdAuthority/authorize",
TokenUrl = $"azureAdAuthority/connect/token",
Scopes = new Dictionary<string, string>
OAuth2Definition, "User.Read"
);
options.AddSecurityRequirement(new Dictionary<string, IEnumerable<string>> OAuth2Definition, null);
);
services.AddCors(options => options.AddPolicy("AllowSpecificOrigin", builder => builder
.WithOrigins(Configuration["MyAppClientUrl"])
.AllowCredentials()
.AllowAnyHeader()
.AllowAnyMethod()
));
// Other Service Registrations.
public void Configure(IApplicationBuilder app, IHostingEnvironment env)
app.UseMiddleware<ErrorHandlingMiddleware>();
app.UseCors("AllowSpecificOrigin");
app.UseHsts();
app.UseHttpsRedirection();
app.UseSwagger();
app.UseSwaggerUI(config =>
const string swaggerName = "MyApp Coding Api";
const string swaggerUrl = "/swagger/v1/swagger.json";
config.SwaggerEndpoint(swaggerUrl, swaggerName);
config.RoutePrefix = string.Empty;
config.OAuthAppName(swaggerName);
config.OAuthClientId(Configuration["AzureAd:ClientId"]);
config.OAuthClientSecret(Configuration["AzureAd:ClientSecret"]);
// This is my Api local path.
config.OAuthRealm("https://localhost:44398/swagger/ui/o2c-html");
config.OAuthScopeSeparator(" ");
);
app.UseAuthentication();
app.UseMvc();
以下是客户端生成的token,工作正常,实现.v2.0:
"aud": "Excldued",
"iss": "https://login.microsoftonline.com/Excldued/v2.0",
"iat": 1556730915,

但是swagger生成如下token,即.v1.0:

我在请求 1.0 端点并获取错误令牌类型的 Swagger 配置中做错了什么?
更新:
这是对 Azure AD 授权端点的提琴手请求:

【问题讨论】:
嗨,Saeid,您是否可以在本地托管它并获取提琴手/网络跟踪以查看 Swagger 真正在做什么?如果是这样,您能否提供大摇大摆的 URL 是什么?看起来 configureservices 方法设置正确,所以它应该转到 v2.0 端点, 嘿@FrankHu。我用 Fiddler 请求更新了这个问题。奇怪的是,该 API 可以与使用 MSAL 库进行身份验证的客户端 SPA 应用程序一起正常工作。它只是不适用于 Swagger 或 Postman。不过,感谢您对此进行检查。 如果您愿意,我可以让您与技术支持部门联系以仔细查看。查看完整的提琴手跟踪可能很有用。我不确定该请求是否是 Swagger 请求。您可以通过 AzCommunity@microsoft.com 给我发送电子邮件,并在电子邮件中包含指向该主题的链接,这样我就可以为您启用免费支持请求。 @Saeid 你是怎么解决的? 【参考方案1】:您获得 v1.0 令牌的原因是您尝试访问 v1.0 资源。请在此处查看文章:https://docs.microsoft.com/en-us/azure/active-directory/develop/access-tokens
访问令牌是根据令牌的受众创建的,即拥有令牌范围的应用程序。这就是将应用清单中的资源设置 accessTokenAcceptedVersion 为 2 允许调用 v1.0 端点的客户端接收 v2.0 访问令牌的方式。同样,这就是为什么更改客户端的访问令牌可选声明不会更改在为 user.read 请求令牌时收到的访问令牌,该令牌由 MS Graph 资源拥有。 出于同样的原因,在使用个人帐户(例如 hotmail.com 或 Outlook.com)测试您的客户端应用程序时,您可能会发现您的客户端收到的访问令牌是一个不透明的字符串。这是因为正在访问的资源请求了已加密且客户端无法理解的旧版 MSA(Microsoft 帐户)票证。
您的 v1.0 令牌具有 Microsoft Graph 的受众,该受众由 v1.0 端点颁发。如果您在此处关注文章:https://docs.microsoft.com/en-us/azure/active-directory/develop/v2-oauth2-auth-code-flow 您会看到,即使在访问 v2.0 端点并使用 Postman 为资源 graph.microsoft.com 请求访问令牌时,您也会在 iss 没有 v2.0 的情况下获得访问令牌。
这也是一个非常有用的资源,因为它很好地参考了 Azure 中一些流行的 GUID。 :https://www.shawntabrizi.com/aad/common-microsoft-resources-azure-active-directory/
