ASP.NET Core MVC Hangfire自定义身份验证

Question

我设法在我的ASP.NET Core MVC应用程序上使用Hangfire，现在我试图添加管理员授权。

我将以下代码添加到Startup.cs文件中：

app.UseHangfireDashboard("/hangfire", new DashboardOptions
 {
    Authorization = new[] {new  SecurityHelpers.AdminAuthorization.HangFireAuthorizationFilter() }
 });

app.UseHangfireServer();
RecurringJob.AddOrUpdate( () => Debug.WriteLine("Minutely Job"), Cron.Minutely);

现在，我对自定义授权过滤器有疑问：

public class HangFireAuthorizationFilter : IDashboardAuthorizationFilter
{
    public bool Authorize(DashboardContext context)
    {
        return true;
    }
}

有一些使用IAutohorizationFilter进行旧配置的示例，并且在版本1.6.8中，有一个新接口IDashboardAuthorizationFilter，我不知道如何实现它。

我的Web应用程序使用声明。

在 Hangfire 中为 asp.net core 添加自定义基本身份验证

使用 Hangfire.Dashboard.Basic.Authentication nuget 包。

使用命令安装

Install-Package Hangfire.Dashboard.Basic.Authentication

参考

在启动配置方法中添加以下内容

app.UseHangfireDashboard("/hangfire", new DashboardOptions
        {
            //AppPath = "" //The path for the Back To Site link. Set to null in order to hide the Back To  Site link.
            DashboardTitle = "My Website",
            Authorization = new[]
        {
                new HangfireCustomBasicAuthenticationFilter{
                    User = _configuration.GetSection("HangfireSettings:UserName").Value,
                    Pass = _configuration.GetSection("HangfireSettings:Password").Value
                }
            }
        });

在 appsettings.json 中添加以下内容（使用您的用户名和密码）

 "HangfireSettings": {
     "UserName": "admin",
     "Password": "password"
 }

这是我对.NET Core的实现：

public class HangfireAuthorizationFilter : IDashboardAuthorizationFilter {
    private string policyName;

    public HangfireAuthorizationFilter(string policyName) {
        this.policyName = policyName;
    }

    public bool Authorize([NotNull] DashboardContext context) {
        var httpContext = context.GetHttpContext();
        var authService = httpContext.RequestServices.GetRequiredService<IAuthorizationService>();
        return authService.AuthorizeAsync(httpContext.User, this.policyName).ConfigureAwait(false).GetAwaiter().GetResult();
    }
}

使用以下命令进行设置Startup Configure：

app.UseHangfireDashboard(
            pathMatch: "/hangfire",
            options: new DashboardOptions() {
                Authorization = new IDashboardAuthorizationFilter[] {
                    new HangfireAuthorizationFilter("somePolicy")
                }
            });

确保您先前选择的策略（例如“ somePolicy”）已设置Startup ConfigureServices。例如：

services.Configure<AuthorizationOptions>(options => {
    options.AddPolicy("somePolicy", policy => {
        // require the user to be authenticated
        policy.RequireAuthenticatedUser();
        // Maybe require a claim here, if you need that.
        //policy.RequireClaim(ClaimTypes.Role, "some role claim");
    });
};

如果您使用 .NET Core 2.0，则需要自定义实现以符合新的身份验证标准。

您需要添加一个中间件。这个是由 HangFire 在他们的 Github 页面/问题中提供的。

public class HangfireDashboardMiddleware
{
    private readonly DashboardOptions _dashboardOptions;
    private readonly JobStorage _jobStorage;
    private readonly RequestDelegate _nextRequestDelegate;
    private readonly RouteCollection _routeCollection;

    public HangfireDashboardMiddleware(
        RequestDelegate nextRequestDelegate,
        JobStorage storage,
        DashboardOptions options,
        RouteCollection routes)
    {
        _nextRequestDelegate = nextRequestDelegate;
        _jobStorage = storage;
        _dashboardOptions = options;
        _routeCollection = routes;
    }

    public async Task Invoke(HttpContext httpContext)
    {
        var aspNetCoreDashboardContext =
            new AspNetCoreDashboardContext(_jobStorage, _dashboardOptions, httpContext);

        var findResult = _routeCollection.FindDispatcher(httpContext.Request.Path.Value);
        if (findResult == null)
        {
            await _nextRequestDelegate.Invoke(httpContext);
            return;
        }

        // attempt to authenticate against default auth scheme (this will attempt to authenticate using data in request, but doesn't send challenge)
        var result = await httpContext.AuthenticateAsync();

        if (!httpContext.User.Identity.IsAuthenticated)
        {
            // request was not authenticated, send challenge and do not continue processing this request
            await httpContext.ChallengeAsync();
        }

        if (_dashboardOptions
            .Authorization
            .Any(filter =>
                     filter.Authorize(aspNetCoreDashboardContext) == false))
        {
            var isAuthenticated = httpContext.User?.Identity?.IsAuthenticated;
            httpContext.Response.StatusCode = isAuthenticated == true
                                                  ? (int) HttpStatusCode.Forbidden
                                                  : (int) HttpStatusCode.Unauthorized;
            return;
        }

        aspNetCoreDashboardContext.UriMatch = findResult.Item2;
        await findResult.Item1.Dispatch(aspNetCoreDashboardContext);
    }
}

然后在你的 Startup.cs 中你需要添加这个方法

private static IApplicationBuilder UseHangfireDashboardCustom(IApplicationBuilder app,string pathMatch = "/hangfire",DashboardOptions options = null,JobStorage storage = null)
{
    var services = app.ApplicationServices;
    storage = storage ?? services.GetRequiredService<JobStorage>();
    options = options ?? services.GetService<DashboardOptions>() ?? new DashboardOptions();
    var routes = app.ApplicationServices.GetRequiredService<RouteCollection>();

    app.Map(new PathString(pathMatch), x =>
        x.UseMiddleware<HangfireDashboardMiddleware>(storage, options, routes));

    return app;
}

最后，使用自定义授权

    public void Configure(IApplicationBuilder app, IHostingEnvironment env)
    {
        if (env.IsDevelopment())
        {
            app.UseDeveloperExceptionPage();
            app.UseBrowserLink();
            app.UseDatabaseErrorPage();
        }
        else
        {
            app.UseExceptionHandler("/Home/Error");
        }

        app.UseStaticFiles();

        app.UseAuthentication();

        app.UseMvc(routes => routes.MapRoute(
                       "default",
                       "{controller=Home}/{action=Index}/{id?}"));

        app.UseHangfireServer();

        //Voila!
        UseHangfireDashboardCustom(app);
    }

这就是我的实现方式IDashboardAuthorizationFilter

public class HangfireAuthorizeFilter : IDashboardAuthorizationFilter
{
    public bool Authorize(DashboardContext context)
    {
        var owinEnvironment = context.GetOwinEnvironment();
        if (owinEnvironment.ContainsKey("server.User"))
        {
            if (owinEnvironment["server.User"] is ClaimsPrincipal)
            {
                return (owinEnvironment["server.User"] as ClaimsPrincipal).Identity.IsAuthenticated;
            }
            else if (owinEnvironment["server.User"] is GenericPrincipal)
            {
                return (owinEnvironment["server.User"] as GenericPrincipal).Identity.IsAuthenticated;
            }
        }
        return false;
    }
}

在你的启动中

app.UseHangfireDashboard("/hangfire", new DashboardOptions
{
    Authorization = new [] { new HangfireAuthorizeFilter() }
});
