Asp.net core Web API for SPA - 如何实现 Swagger 身份验证，而无需在 Web API 外部获取访问令牌并传递它？

Question

我们正在使用 React 和 ASP.Net core Web API 构建 SPA。

React 会将 Auth_Token 传递给 ASP.Net core Web API 进行身份验证，这是可行的。

front-end application由于应用程序注册是与 一起完成的Scope & Roles，我不确定如何在 ASP.Net core Web API 中实现 Swagger 的身份验证。

目前我有以下swagger配置

    private void AddSwagger(IServiceCollection services)
    {
        services.AddSwaggerGen(c =>
        {
            c.SwaggerDoc("v1", new OpenApiInfo
            {
                Version = "v1",
                Title = "Track Management API",
            });

            var xmlCommentsFile = $"{Assembly.GetExecutingAssembly().GetName().Name}.xml";
            var xmlCommentsFullPath = Path.Combine(AppContext.BaseDirectory, xmlCommentsFile);

            c.IncludeXmlComments(xmlCommentsFullPath);

            var jwtSecurityScheme = new OpenApiSecurityScheme
            {
                Scheme = "bearer",
                BearerFormat = "JWT",
                Name = "JWT Authentication",
                In = ParameterLocation.Header,
                Type = SecuritySchemeType.Http,
                Description = "Put **_ONLY_** your JWT Bearer token on textbox below!",

                Reference = new OpenApiReference
                {
                    Id = JwtBearerDefaults.AuthenticationScheme,
                    Type = ReferenceType.SecurityScheme
                }
            };

            c.AddSecurityDefinition(jwtSecurityScheme.Reference.Id, jwtSecurityScheme);

            c.AddSecurityRequirement(new OpenApiSecurityRequirement
            {
                { jwtSecurityScheme, Array.Empty<string>() }
            });
        });
    }

目前，我们必须在 ASP.Net core Web API 外部获取 Auth_Token 并将其传递给它。

开发者能否直接从Swagger页面生成所需的Auth_Token来简化这个过程？

更新：下面的 Swagger 配置尝试获取所需的 auth_code 但it uses the Web API URL as the redirection URL失败。我想要的是它应该使用前端 URL 作为重定向 URL 来生成 auth_code 但将其传递给 Web API？

            c.AddSecurityDefinition("oauth2", new OpenApiSecurityScheme
            {
                Description = "OAuth2.0 Auth Code with PKCE",
                Name = "oauth2",
                Type = SecuritySchemeType.OAuth2,
                Flows = new OpenApiOAuthFlows
                {
                    AuthorizationCode = new OpenApiOAuthFlow
                    {
                        AuthorizationUrl = new Uri($"https://login.microsoftonline.com/{this.Configuration.GetValue<string>("AzureAd:TenantId")}/oauth2/authorize"),
                        TokenUrl = new Uri($"https://login.microsoftonline.com/{this.Configuration.GetValue<string>("AzureAd:TenantId")}/v2.0/token"),
                        Scopes = new Dictionary<string, string>
                        {
                            { this.Configuration.GetValue<string>("AzureAd:ApiScope"), "Allows Read and Write" }
                        }
                    }
                }
            });
            c.AddSecurityRequirement(new OpenApiSecurityRequirement
            {
                {
                    new OpenApiSecurityScheme
                    {
                        Reference = new OpenApiReference { Type = ReferenceType.SecurityScheme, Id = "oauth2" }
                    },
                    new[] { this.Configuration.GetValue<string>("AzureAd:ApiScope") }
                }
            }); 

我看到的另一个选项是在较低环境的应用程序注册中添加 Web API URL 作为重定向 URL。

这与 Azure AD B2C 结合使用对我有用：

config.AddSecurityDefinition("oauth2", new OpenApiSecurityScheme
{
    Type = SecuritySchemeType.OAuth2,
    Scheme = "oauth2",
    OpenIdConnectUrl = new Uri(builder.Configuration["AzureAd:Authority"]),
    Flows = new OpenApiOAuthFlows
    {
        Implicit = new OpenApiOAuthFlow
        {
            AuthorizationUrl = new Uri(builder.Configuration["AzureAd:Authority"], UriKind.Absolute),
            Scopes = new Dictionary<string, string>
                {
                    { builder.Configuration["AzureAd:Scopes"], "Access web API" },
                }
        }
    }
});

config.AddSecurityRequirement(new OpenApiSecurityRequirement
    {
        {
            new OpenApiSecurityScheme
            {
                Reference = new OpenApiReference { Type = ReferenceType.SecurityScheme, Id = "oauth2" }
            },
            new[] { builder.Configuration["AzureAd:Scopes"] }
        }
    });
