asp.net-core-webapi - .NET Core 3 API - 在一个请求后停止工作？

Question

我遇到了一个奇怪的问题，请求只能工作一次。它发生在 IIS 和 IIS Express 中。如果我重新启动/回收，它会再次工作，但仍然只有一次。放置断点显示后续请求永远不会到达 Controller ...

[HttpGet("private/{zipCode}")]
public IActionResult PrivateZipSearch(string zipCode)

启动.配置

public void Configure(IApplicationBuilder app, IWebHostEnvironment env, IServiceProvider srv, ILoggerFactory loggerFactory)
{
     loggerFactory.AddProvider(new DbLoggerProvider(this.Configuration, srv.GetService<IHttpContextAccessor>()));

     app.UseHttpsRedirection(); // Redirect HTTP -> HTTPS
     app.UseRouting();
     {
         app.UseCors(Config.Settings.Cors.PolicyName);
         app.UseAuthentication();
     }

     // Hangfire
     {
         app.UseHangfireDashboard();
         app.UseHangfireServer();
     }

     app.UseMiddleware<LoggingMiddleware>();
     app.UseMiddleware<OptionsVerbMiddleware>();

     // Must be last!
     app.UseEndpoints(x => x.MapControllers());
 }

如有任何建议，我们将不胜感激!谢谢!

原来是因为我将 HttpContext 设置为一个字段。

有很多该做和不该做的事情，可以在这里找到: https://github.com/davidfowl/AspNetCoreDiagnosticScenarios/blob/master/AspNetCoreGuidance.md#do-not-store-ihttpcontextaccessorhttpcontext-in-a-field
