swagger asp..net核心3.1的隐式承载流

Question

是否有一种方法可以自动将承载令牌放入Swagger中的每个请求？我不想在应该与身份交互的地方使用oauth隐式流。

我想为我的api提供一个庞大的端点，它可以获取访问令牌并自动将其放入每个请求。

Answer 1

在您的startup.s类中：

// prevent from mapping "sub" claim to nameidentifier.
JwtSecurityTokenHandler.DefaultInboundClaimTypeMap.Remove("sub");

var identityUrl = configuration.GetValue<string>("IdentityUrl");

services.AddAuthentication(options =>
{
    options.DefaultAuthenticateScheme = JwtBearerDefaults.AuthenticationScheme;
    options.DefaultChallengeScheme = JwtBearerDefaults.AuthenticationScheme;
})
.AddJwtBearer(options =>
{
    options.Authority = identityUrl;
    options.RequireHttpsMetadata = false;
    options.Audience = "demo_api";
});

SwaggerGen

    services.AddSwaggerGen(options =>
    {
      ...
        options.AddSecurityDefinition("oauth2", new OpenApiSecurityScheme
       {
            Type = SecuritySchemeType.OAuth2,
            Flows = new OpenApiOAuthFlows
            {
                Implicit = new OpenApiOAuthFlow
                {
                    AuthorizationUrl = new Uri($"{configuration.GetValue<string>("IdentityUrl")}/connect/authorize"),
                    TokenUrl = new Uri($"{configuration.GetValue<string>("IdentityUrl")}/connect/token"),
                    Scopes = new Dictionary<string, string>()
                    {
                        { "api1", "Demo API - full access" }
                    }
                }
            }
        });

操作过滤器

options.OperationFilter<AuthorizeCheckOperationFilter>();

实施

public class AuthorizeCheckOperationFilter : IOperationFilter
{
    public void Apply(OpenApiOperation operation, OperationFilterContext context)
    {
        var hasAuthorize = context.MethodInfo.DeclaringType.GetCustomAttributes(true).OfType<AuthorizeAttribute>().Any() ||
                           context.MethodInfo.GetCustomAttributes(true).OfType<AuthorizeAttribute>().Any();

        if (!hasAuthorize) return;

        var unauthorizedHashCode = HttpStatusCode.Unauthorized.GetHashCode().ToString();
        var unauthorizedDescription = HttpStatusCode.Unauthorized.ToString();

        var forbiddenHashCode = HttpStatusCode.Forbidden.GetHashCode().ToString();
        var forbiddenDescription = HttpStatusCode.Forbidden.ToString();

        operation.Responses.TryAdd(unauthorizedHashCode, new OpenApiResponse { Description = unauthorizedDescription });
        operation.Responses.TryAdd(forbiddenHashCode, new OpenApiResponse { Description = forbiddenDescription });

        var oAuthScheme = new OpenApiSecurityScheme
        {
            Reference = new OpenApiReference { Type = ReferenceType.SecurityScheme, Id = "oauth2" }
        };

        operation.Security = new List<OpenApiSecurityRequirement>
        {
            new OpenApiSecurityRequirement
            {
                [ oAuthScheme ] = new [] { "api1" }
            }
        };

    }
}

使用此

// Keep both UseAuthentication and UseAuthorization IN THIS ORDER
app.UseAuthentication();
app.UseAuthorization();

使用摇摇杆

app.UseSwagger(c =>
        {
            c.RouteTemplate = "swagger/{documentName}/swagger.json";
        });
        app.UseSwaggerUI(s =>
        {
            s.SwaggerEndpoint("/swagger/v1/swagger.json", "Your awesome project name");

            s.OAuthAppName("My API - Swagger");
            s.OAuthClientId("client");

            // Should match the client RedirectUrl in the IdentityServer
            s.OAuth2RedirectUrl("https://localhost:5001/swagger/oauth2-redirect.html");
        });

您的控制器

[Authorize]
[ApiController]
[Route("api/[controller]")] // TODO: Take care of the versioning
public class IndentityController : ControllerBase
{
    ...

现在在IdentityServer项目中。 ApiResources：

public static IEnumerable<ApiResource> GetApiResources()
    {
        return new List<ApiResource>
        {
            new ApiResource("api1", "My API")
        };
    }

最后，您的客户应如下所示：

new Client
{
    ClientId = "client",
    AllowedGrantTypes = GrantTypes.Implicit,
    RedirectUris = { "https://localhost:5001/swagger/oauth2-redirect.html" },
    AllowedScopes = { "api1" },
    AllowAccessTokensViaBrowser = true,
    RequireConsent = false
}
