我在应用程序上使用 hangfire,我需要使用我的存储库进行仪表板身份验证。为此,我必须在 Hangfire 的 Authorize 方法中解析存储库,但是使用 OwinContext
我一直无法这样做。我选择在这个项目中使用 SimpleInjector,因为它在 WebApiConfig
的 Register
方法中注册了所有东西,所以我想访问它。最近我使用了一个 middleware
作为 MessageHandler
,然后我成功地使用 HttpRequestMessage
解决了一个依赖项。但是在 OwinContext
上,我无法使用 HttpRequestMessage.GetDependencyScope()
访问它并通过它解决依赖项。
这是 Hangfire 建议在其文档中对 Asp.net 应用进行身份验证的方式;
public class MyAuthorizationFilter : IDashboardAuthorizationFilter
{
public bool Authorize(DashboardContext context)
{
// In case you need an OWIN context, use the next line, `OwinContext` class
// is the part of the `Microsoft.Owin` package.
var owinContext = new OwinContext(context.GetOwinEnvironment());
// Allow all authenticated users to see the Dashboard (potentially dangerous).
return owinContext.Authentication.User.Identity.IsAuthenticated;
}
}
由于我在前端使用 Angular
,因此 owinContext.Authentication.User
为空。即使不是这样,我也只希望自己够到仪表板。所以这不能解决我的问题。
如何在 Authorize
方法中解决我的依赖关系?
我不能通过构造函数注入来做到这一点,因为对于 Hangfire,你在 UseHangfireDashboard
的 Startup.cs
上说 Configuration
如下所述;
这是我的 Startup.cs
文件
private IEnumerable<IDisposable> GetHangfireServers()
{
Hangfire.GlobalConfiguration.Configuration
.SetDataCompatibilityLevel(CompatibilityLevel.Version_170)
.UseSimpleAssemblyNameTypeSerializer()
.UseRecommendedSerializerSettings()
.UseSqlServerStorage("CONN_STR", new SqlServerStorageOptions
{
CommandBatchMaxTimeout = TimeSpan.FromMinutes(5),
SlidingInvisibilityTimeout = TimeSpan.FromMinutes(5),
QueuePollInterval = TimeSpan.Zero,
UseRecommendedIsolationLevel = true,
DisableGlobalLocks = true
});
yield return new BackgroundJobServer();
}
public void Configuration(IAppBuilder app)
{
app.UseHangfireAspNet(GetHangfireServers);
app.UseHangfireDashboard("/hangfire", new DashboardOptions {
Authorization = new [] {
new DashboardAuthorization()
/* explanation */
// for DI to work through constructor,
//I have to give my AuthRepository as a parameter here.
//And my AuthRepository also has many DIs so,
//it's not possible through here.
}
});
BackgroundJob.Enqueue(() => Console.WriteLine("Hello world from Hangfire!"));
}
顺便说一下,我的项目是一个 .Net Framework 4.7.2 项目。
答案 0 :(得分:1)
就 Hangfire 而言,您负责提供实现 IDashboardAuthorizationFilter 的类的实例。因此,如果该类具有您要注入的依赖项,则需要您进行连接。最好在您的 DI 容器中注册该类型及其依赖项,并让它为您解析一个实例。这样它就可以通过构造函数注入为您注入所有依赖项。
您应该在 Startup.cs 中得到类似这样的模式,您可以在其中配置 OWIN 管道。
public void Configuration(IAppBuilder app)
{
var container = CreateContainerWithRegisteredServices();
var dashboardFilter = container.Resolve<IDashboardAuthorizationFilter>();
app.UseHangfireDashboard("/hangfire", new DashboardOptions {
Authorization = new [] { dashboardFilter }
});
BackgroundJob.Enqueue(() => Console.WriteLine("Hello world from Hangfire!"));
// Configure Web API, SignalR, or whatever else hangs off your OWIN pipeline.
// You can pass the container into their configure methods if necessary.
}
IContainer CreateContainerWithRegisteredServices()
{
//this method will look different depending on your chosen IoC library
var container = SomeIoCLibrary.CreateContainer();
container.Register<MyAuthorizationFilter, IDashboardAuthorizationFilter>();
//register other dependencies here
return container;
}
