带有JWT身份验证的RestSharp不起作用

[英]RestSharp with JWT-authentication doesn't work

这是我“学习”如何做的页面: https : //stormpath.com/blog/token-authentication-asp-net-core

但是对我来说这不起作用(也不适用于Fiddler)我的ApplicationUser-model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);
    }
}

我的包装是RestSharp的,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;
}

我想从Web客户端应用程序中使用JWT(令牌身份验证)登录。 登录后,我得到这个如的access_token: eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiJURVNUIiwianRpIjoiZTBjYjE0NjgtYzBmOS00ZTM4LTg4ZjgtMGM4ZjNmYjMyNjZmIiwiaWF0IjoxNDcwOTUwMTA0LCJuYmYiOjE0NzA5NTAxMDQsImV4cCI6MTQ3MDk1MDQwNCwiaXNzIjoiRXhhbXBsZUlzc3VlciIsImF1ZCI6IkV4YW1wbGVBdWRpZW5jZSJ9.a9_JK2SG3vzc6NSOB0mZXqHlM9UAEXUHHrrijAQUsX0

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

包装器调用如下所示:

//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);

此处userAfterLogin为null。

自两个星期以来,我一直在尝试获取登录信息,但仍然无法正确登录。

知道我在做什么错吗? 也许是错误的授权请求标头值?

更新资料

这是我的Startup.Configure,配置为使用Bearer / JWT:

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?}");
    });
}

如果您收到授权错误或使用邮递员,您将意识到您被要求重定向到登录名,只需使用以下命令装饰您的班级:

[Authorize(AuthenticationSchemes = "Bearer")]

默认情况下,.Net使用基于cookie的身份验证,带有该注释的您将粘贴到基于令牌的令牌中

因此,您正在使用2个中间件进行身份验证。 一个由asp.net身份提供(基于cookie),另一个由令牌提供。 现在,两个中间件都使用相同的属性来处理请求[授权]。 更精确地看一下这里的代码

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

对于JWTBearer

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

饼干

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

但是因为它们都处于活动状态,所以对于没有cookie或JwtBearer的请求,它们中的任何一个都将返回Unauthorized。

对于您要寻找的解决方案,您需要在现有的cookie和令牌的基础上创建一个中间件,以根据是否存在授权标头将请求路由到其中一个。

在Fiddler中,您将看到是否将您重定向到登录页面(它将报告2个结果,其中一个为302(重定向),然后为404)-是这样吗?

您已激活DebugLogger,因此请尝试AddDebug(LogLevel.Trace)并查看“调试”输出窗口,这对于分析哪些身份验证步骤失败非常有帮助。 它还显示身份验证是否失败或授权,以及是否具有有效的令牌等。因此,它指出了查找问题的方向。
