c# - asp.net core 在前一个操作完成之前在此上下文上启动了第二个操作

问题描述

我有一个 ASP.Net Core 2 Web 应用程序。

我正在尝试创建一个自定义路由中间件，这样我就可以从数据库中获取路由。

在 ConfigureServices 我有：

services.AddDbContext<DbContext>(options => options.UseMySQL(configuration.GetConnectionString("ConnectionClient")));
services.AddScoped<IServiceConfig, ServiceConfig>();

在配置中：

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

在 RouteCustom

public class RouteCustom : IRouteCustom
{
    private readonly IRouter _innerRouter;
    private IServiceConfig _serviceConfig;

    public RouteCustom(IRouter innerRouter)
    {
        _innerRouter = innerRouter ?? throw new ArgumentNullException(nameof(innerRouter));
    }

    public async Task RouteAsync(RouteContext context)
    {
        _serviceConfig = context.HttpContext.RequestServices.GetRequiredService<IServiceConfig>();
        ...
        Operations inside _serviceConfig to get the route
    }

    public VirtualPathData GetVirtualPath(VirtualPathContext context)
    {
        _serviceConfig = context.HttpContext.RequestServices.GetRequiredService<IServiceConfig>();
        ...
        Operations inside _serviceConfig to get the route
    }
}

IServiceConfig 它只是我访问数据库以获取数据的一个类，在这种情况下是路由，还有我需要的应用程序配置数据。

public interface IServiceConfig
{
    Config GetConfig();
    List<RouteWeb> SelRoutesWeb();
}

public class ServiceConfig : IServiceConfig
{
    private readonly IMemoryCache _memoryCache;
    private readonly IUnitOfWork _unitOfWork;
    private readonly IServiceTenant _serviceTenant;

    public ServiceConfig(IMemoryCache memoryCache, IUnitOfWork unitOfWork, IServiceTenant serviceTenant)
    {
        _memoryCache = memoryCache;
        _unitOfWork = unitOfWork;
        _serviceTenant = serviceTenant;
    }


    public Config GetConfig()
    {
        var cacheConfigTenant = Names.CacheConfig + _serviceTenant.GetId();

        var config = _memoryCache.Get<Config>(cacheConfigTenant);
        if (config != null) return config;

        config = _unitOfWork.Config.Get();
        _memoryCache.Set(cacheConfigTenant, config, new MemoryCacheEntryOptions() { SlidingExpiration = Names.CacheExpiration });

        return config;
    }


    public List<RouteWeb> SelRoutesWeb()
    {
        var cacheRoutesWebTenant = Names.CacheRoutesWeb + _serviceTenant.GetId();

        var routesWebList = _memoryCache.Get<List<RouteWeb>>(cacheRoutesWebTenant);
        if (routesWebList != null) return routesWebList;

        routesWebList = _unitOfWork.PageWeb.SelRoutesWeb();
        _memoryCache.Set(cacheRoutesWebTenant, routesWebList, new MemoryCacheEntryOptions() { SlidingExpiration = Names.CacheExpiration });

        return routesWebList;
    }
}

问题是我在打开多个选项卡进行测试并尝试同时刷新所有选项卡时收到此消息：“在前一个操作完成之前，在此上下文上启动了第二个操作”

我确定我做错了什么，但我不知道是什么。它必须是访问自定义路由中间件中的数据库的更好方法，甚至是更好的方法。

例如，在常规中间件（不是路由中间件）上，我可以将依赖项注入到 Invoke 函数中，但我不能在此处将依赖项注入到 RouteAsync 或 GetVirtualPath。

这里会发生什么？

提前致谢。

更新这些是我得到的例外。我觉得有关系...

这是工作单元

public interface IUnitOfWork : IDisposable
{
    ICompanyRepository Company { get; }
    IConfigRepository Config { get; }
    ...

    void Complete();
}


public class UnitOfWork : IUnitOfWork
{
    private readonly DbContext _context;

    public UnitOfWork(DbContext context)
    {
        _context = context;

        Company = new CompanyRepository(_context);
        Config = new ConfigRepository(_context);
        ...
    }

    public ICompanyRepository Company { get; private set; }
    public IConfigRepository Config { get; private set; }
    ...

    public void Complete()
    {
        _context.SaveChanges();
    }

    public void Dispose()
    {
        _context.Dispose();
    }
}

更新

在查看了评论并进行了大量测试之后，我得到的最好的线索是当我删除 CustomRoute 行时问题就消失了。从 Startup.cs 上的 Configure 函数中删除此行

routes.Routes.Add(new RouteCustom(routes.DefaultHandler));

我也尝试过删除，首先是 RouteAsync，然后是 GetVirtualPath 方法，但是如果其中一个方法存在，我会收到错误消息，因此很明显问题出在这个 CustomRoute 类中。

在针对任何请求首先调用的 TenantMiddleware 中，我正在注入 UnitOfWork，我没有问题。此中间件是在 Configure 函数中创建的：

app.UseMiddleware<TenantMiddleware>();

在内部，我正在注入 UnitOfWork，并在每个请求中使用它，如下所示：

public async Task Invoke(HttpContext httpContext, IServiceTenant serviceTenant) { ...执行数据库操作以检索租户的数据。

}

public class ServiceTenant : IServiceTenant
{
    public ServiceTenant(IHttpContextAccessor contextAccessor, IMemoryCache memoryCache, IUnitOfWorkMaster unitOfWorkMaster)
    {
        _unitOfWorkMaster = unitOfWorkMaster;
    }

    ...performing DB operations
}

因此，CustomROute 的问题是我无法通过添加到 Invoke 函数来注入依赖项，如下所示：

public async Task Invoke(HttpContext httpContext, IServiceTenant serviceTenant)

所以我必须像这样调用相应的服务（在该服务中我注入 UnitOfWork 并执行数据库操作），我认为这可能是导致问题的原因：

public async Task RouteAsync(RouteContext context)
{
    _serviceConfig = context.HttpContext.RequestServices.GetRequiredService<IServiceConfig>();
    ....
}

因为这是我知道将 IServiceConfig“注入”到 RouteAsync 和 GetVirtualPath 中的唯一方法......

另外，由于我使用的是 BaseCONtroller，所以我在每个控制器中都这样做，所以我决定使用哪个操作系统的注入服务......

public class BaseWebController : Controller
{
    private readonly IMemoryCache _memoryCache;
    private readonly IUnitOfWork _unitOfWork;
    private readonly IUnitOfWorkMaster _unitOfWorkMaster;
    private readonly IServiceConfig _serviceConfig;
    private readonly IServiceFiles _serviceFiles;
    private readonly IServiceFilesData _serviceFilesData;
    private readonly IServiceTenant _serviceTenant;

    public BaseWebController(IServiceProvider serviceProvider)
    {
        _memoryCache = serviceProvider.GetRequiredService<IMemoryCache>();
        _unitOfWork = serviceProvider.GetRequiredService<IUnitOfWork>();
        _unitOfWorkMaster = serviceProvider.GetRequiredService<IUnitOfWorkMaster>();
        _serviceConfig = serviceProvider.GetRequiredService<IServiceConfig>();
        _serviceFiles = serviceProvider.GetRequiredService<IServiceFiles>();
        _serviceFilesData = serviceProvider.GetRequiredService<IServiceFilesData>();
        _serviceTenant = serviceProvider.GetRequiredService<IServiceTenant>();        }
    ...
}

然后在每个控制器中，而不是引用所有注入的服务，我可以只为我需要的那些服务，像这样：

public class HomeController : BaseWebController
{
    private readonly IUnitOfWork _unitOfWork;

    public HomeController(IServiceProvider serviceProvider) : base(serviceProvider)
    {
        _unitOfWork = serviceProvider.GetRequiredService<IUnitOfWork>();
    }

    public IActionResult Index()
    {
        ...
    }
}

我不知道这是否与我的问题有关，但我只是向您展示我认为可能是问题所在，以便您获得更多信息。

谢谢。

更新

这是检索路由的数据库代码：

public class PageWebRepository : Repository<PageWeb>, IPageWebRepository
{
    public PageWebRepository(DbContext context) : base(context) { }


    public List<RouteWeb> SelRoutesWeb()
    {
        return Context.PagesWebTrs.Include(p => p.PageWeb).Where(p => p.PageWeb.Active)
            .Select(p => new RouteWeb
            {
                PageWebId = p.PageWebId,
                LanguageCode = p.LanguageCode,
                Route = p.Route,
                Regex = p.PageWeb.Regex.Replace("<route>", p.Route),
                Params = p.PageWeb.Params,
                Area = p.PageWeb.Area,
                Controller = p.PageWeb.Controller,
                Action = p.PageWeb.Action,
                Type = p.PageWeb.Type,
                Sidebar = p.PageWeb.Sidebar,
                BannerIsScript = p.PageWeb.BannerIsScript,
                Title = p.Title,
                Description = p.Description,
                Keywords = p.Keywords,
                ScriptHead = p.ScriptHead,
                ScriptBody = p.ScriptBody,
                BannerScript = p.BannerScript,
                BannerUrl = p.BannerUrl,
            }).ToList();
    }
}

其中 PagesWebTrs 是页面的翻译（多语言），PagesWeb 是主表。

解决方案

这个问题确实在路由中间件内。

根据定义，中间件是一个单例，因此单个实​​例处理所有请求。这导致多个同时请求访问和更改实例状态（已the IServiceConfig连接）；DbContext这是一个伪装得很好的经典并发问题。

一个例子。

请求 A 执行RouteAsync、设置_serviceConfig并在 上执行查询DbContext。纳秒（或更少:)）之后，请求 B 也会这样做。在执行请求 B 的查询时，请求 A 执行GetVirtualPath，但这次是在DbContext请求 B 的集合上执行。这导致在DbContext请求 B 上执行第二个查询，该请求仍然在运行，您会收到提到的错误。

IServiceConfig解决方案是通过在每个方法的开头检索 来防止共享状态。

正如您已经说过的，通过该方法注入这样的依赖项Invoke是行不通的；该Invoke方法没有被执行。

下面是重做的RouteCustom.

public class RouteCustom : IRouteCustom
{
    private readonly IRouter _innerRouter;

    public RouteCustom(IRouter innerRouter)
    {
        _innerRouter = innerRouter ?? throw new ArgumentNullException(nameof(innerRouter));
    }

    public async Task RouteAsync(RouteContext context)
    {
        var serviceConfig = context.HttpContext.RequestServices.GetRequiredService<IServiceConfig>();
        // ...

    }

    public VirtualPathData GetVirtualPath(VirtualPathContext context)
    {
        var serviceConfig = context.HttpContext.RequestServices.GetRequiredService<IServiceConfig>();
        // ...

    }
}
