使用JWT身份验证的RestSharp不起作用

Question

这是我"学习"如何操作的页面:https://stormpath.com/blog/token-authentication-asp-net-core

但对我来说这不起作用(也不适用于Fiddler)我的ApplicationUser模型有这个控制器:

[Authorize] //works when it's not set, doesn't work when it's set
[Route("api/[controller]")]
public class ApplicationUserController : Controller
{
    private IRepository<ApplicationUser> _applicationUserRepository;

    public ApplicationUserController(IRepository<ApplicationUser> applicationUserRepository)
    {
        _applicationUserRepository = applicationUserRepository;
    }

    [HttpGet("{id}")]
    public ApplicationUser Get(int id)
    {
        return _applicationUserRepository.Get(id);
    }
}

并且我的RestSharp包装器可以获取所有应用程序用户:

public Task<T> GetResponseContentAsync<T>(string resource, int id) where T : new()
{
    RestRequest request = new RestRequest($"{resource}/{{id}}", Method.GET);
    request.AddUrlSegment("id", id);
    if (!AuthenticationToken.IsNullOrEmpty(true))
    {
        request.AddHeader("Authorization", string.Format("Bearer {0}", AuthenticationToken));
        _client.Authenticator = new JwtAuthenticator(AuthenticationToken);
        _client.Authenticator.Authenticate(_client, request);
    }

    TaskCompletionSource<T> tcs = new TaskCompletionSource<T>();
    _client.ExecuteAsync<T>(request, response =>
    {
        tcs.SetResult(response.Data);
    });
    return tcs.Task;
}

从我的Web客户端应用程序,我想用JWT(令牌验证)登录什么工作.登录后我得到例如这个access_token: eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiJURVNUIiwianRpIjoiZTBjYjE0NjgtYzBmOS00ZTM4LTg4ZjgtMGM4ZjNmYjMyNjZmIiwiaWF0IjoxNDcwOTUwMTA0LCJuYmYiOjE0NzA5NTAxMDQsImV4cCI6MTQ3MDk1MDQwNCwiaXNzIjoiRXhhbXBsZUlzc3VlciIsImF1ZCI6IkV4YW1wbGVBdWRpZW5jZSJ9.a9_JK2SG3vzc6NSOB0mZXqHlM9UAEXUHHrrijAQUsX0

没有Authorize-attribute我得到ApplicationUser,但是在设置Attribute时,结果为null(因为web-api没有被调用)

wrapper-call看起来像这样:

//this works, token-value is set
string token = new RepositoryCall("http://localhost:54008/").Login("token", "TEST", "TEST123");

string accessToken = JsonConvert.DeserializeObject<Dictionary<string, string>>(token)["access_token"];
ViewData["Result"] = accessToken;

ApplicationUser userAfterLogin = await new RepositoryCall("http://localhost:54008/api") 
    { AuthenticationToken = accessToken }
    .GetResponseContentAsync<ApplicationUser>("ApplicationUser", 2);

这里userAfterLogin是null.

我试图在两周后登录,但我仍然没有把它弄好..

知道我做错了什么吗？授权可能是一个错误的request-header-value？

更新

这是我配置为使用Bearer/JWT的Startup.Configure:

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

    if (env.IsDevelopment())
    {
        app.UseDeveloperExceptionPage();
        app.UseDatabaseErrorPage();
        app.UseBrowserLink();
    }
    else
    {
        app.UseExceptionHandler("/Home/Error");
    }

    app.UseStaticFiles();

    app.UseIdentity();
    var secretKey = "mysupersecret_secretkey!123";
    var signingKey = new SymmetricSecurityKey(Encoding.ASCII.GetBytes(secretKey));

    // Add external authentication middleware below. To configure them please see http://go.microsoft.com/fwlink/?LinkID=532715
    var options = new TokenProviderOptions
    {
        Audience = "ExampleAudience",
        Issuer = "ExampleIssuer",
        SigningCredentials = new SigningCredentials(signingKey, SecurityAlgorithms.HmacSha256),
    };


    var tokenValidationParameters = new TokenValidationParameters
    {
        // The signing key must match!
        ValidateIssuerSigningKey = true,
        IssuerSigningKey = signingKey,

        // Validate the JWT Issuer (iss) claim
        ValidateIssuer = true,
        ValidIssuer = "ExampleIssuer",

        // Validate the JWT Audience (aud) claim
        ValidateAudience = true,
        ValidAudience = "ExampleAudience",

        // Validate the token expiry
        ValidateLifetime = true,

        // If you want to allow a certain amount of clock drift, set that here:
        ClockSkew = TimeSpan.Zero
    };


    app.UseJwtBearerAuthentication(new JwtBearerOptions
    {
        AutomaticAuthenticate = true,
        AutomaticChallenge = true,
        TokenValidationParameters = tokenValidationParameters
    });

    app.UseCookieAuthentication(new CookieAuthenticationOptions
    {
        AutomaticAuthenticate = true,
        AutomaticChallenge = true,
        AuthenticationScheme = "Cookie",
        CookieName = "access_token",
        TicketDataFormat = new CustomJwtDataFormat(
            SecurityAlgorithms.HmacSha256,
            tokenValidationParameters)
    });

    app.UseMiddleware<TokenProviderMiddleware>(Options.Create(options));
    app.UseMvc(routes =>
    {
        routes.MapRoute(
            name: "default",
            template: "{controller=Home}/{action=Index}/{id?}");
    });
}

Answer 1

所以你正在使用 2 个中间件来进行身份验证。一个由 asp.net 身份提供（基于 cookie），另一个基于令牌。现在，两个中间件使用相同的属性来处理请求 [Authorize]。更准确地看这里的代码

https://github.com/aspnet/Security/blob/dev/src/Microsoft.AspNetCore.Authentication.JwtBearer/JwtBearerHandler.cs

对于 JWT 承载者

和

https://github.com/aspnet/Security/blob/dev/src/Microsoft.AspNetCore.Authentication.Cookies/CookieAuthenticationHandler.cs

对于饼干

因为两者都是在中间件管道中激活的，所以当您发送身份验证令牌或 cookie 时，主体将拥有数据。

但由于它们都处于活动状态，因此对于没有 cookie 或 JwtBearer 的请求，它们中的任何一个都会返回 Unauthorized。

对于您正在寻找的解决方案，您需要在现有 cookie 和令牌之上创建一个中间件，以根据授权标头是否存在将请求路由到其中一个。
