Question

当我尝试访问localhost：5000 / hangfire时，我被重定向到错误页面（我有一个返回相对状态页面的控制器（400,404等））

这是我遇到的错误：

我想/ hangfire不存在。它所指的“ HandeErrorCode”来自我的控制器。

[Route ("Error/{statusCode}")]
        public IActionResult HandleErrorCode (int statusCode) {
            var statusCodeData = 
HttpContext.Features.Get<IStatusCodeReExecuteFeature> ();

        switch (statusCode) {
            case 404:
                return View("Status404");
            case 401:
                return View("Status401");
            case 400:
                return View("Status400");    
            case 500:
                return View("Status500");
        }

        return View ();
    }

Startup.cs

ConfigureServices

services.AddHangfire(configuration=>{
              configuration.UsePostgreSqlStorage(connectionString);
          });

配置

app.UseHangfireDashboard("/hangfire");    
      app.UseHangfireServer();

如何访问hangfire仪表板？

Answer 1

对于Hangfire Dashboard，它公开了有关后台作业的敏感信息，包括方法名称和序列化参数，并为您提供了通过执行不同的操作（重试，删除，触发等）来管理它们的机会。限制对仪表板的访问非常重要。

为确保默认情况下的安全，仅允许本地请求，但是您可以通过传递自己的IDashboardAuthorizationFilter接口的实现来更改此设置，该接口的Authorize方法用于允许或禁止请求。第一步是提供您自己的实现。

引用Configuring Authorization

更新：

对此行为已在上面进行了描述，并由HangfireApplicationBuilderExtensions控制。它注册LocalRequestsOnlyAuthorizationFilter。

如果要启用对非本地主机的请求，则需要提供DashboardOptions。

仔细检查此代码，以查看其配置是否正确

public void ConfigureServices(IServiceCollection services)
{
    // Add Hangfire services.
    services.AddHangfire(configuration => configuration
        .SetDataCompatibilityLevel(CompatibilityLevel.Version_170)
        .UseSimpleAssemblyNameTypeSerializer()
        .UseRecommendedSerializerSettings()
        .UseSqlServerStorage(Configuration.GetConnectionString("HangfireConnection"), new SqlServerStorageOptions
        {
            CommandBatchMaxTimeout = TimeSpan.FromMinutes(5),
            SlidingInvisibilityTimeout = TimeSpan.FromMinutes(5),
            QueuePollInterval = TimeSpan.Zero,
            UseRecommendedIsolationLevel = true,
            UsePageLocksOnDequeue = true,
            DisableGlobalLocks = true
        }));

    // Add the processing server as IHostedService
    services.AddHangfireServer();

    // Add framework services.
    services.AddMvc();
}

public void Configure(IApplicationBuilder app, IBackgroundJobClient backgroundJobs, IHostingEnvironment env)
{
    // ...
    app.UseStaticFiles();

    app.UseHangfireDashboard();
    backgroundJobs.Enqueue(() => Console.WriteLine("Hello world from Hangfire!"));

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

您也不需要像这样的hangfire网址

app.UseHangfireDashboard("/hangfire");

只需使用

app.UseHangfireDashboard();

因为文档已经说过here

启动应用程序后，打开以下URL（假设您的应用程序   在5000端口上运行）以访问Hangfire信息中心   接口。如我们所见，我们的后台工作已经完成   成功。

http://localhost:5000/hangfire
