Hello, The temporary solution you suggested seems to work, thanks for your help!
Ok, thank you, let us know about the progress when possible, our project progress is on hold while we cant solve this.
Thanks again
Hi,
Thank you for your suggestions. We have tried both configurations you provided:
Using PreConfigure<ISignalRServerBuilder>
:
PreConfigure<ISignalRServerBuilder>(builder =>
{
builder.AddAzureSignalR(options =>
{
options.ConnectionString = context.Services.GetConfiguration().GetConnectionString("AzureSignalR");
options.ServerStickyMode = Microsoft.Azure.SignalR.ServerStickyMode.Required;
});
});
Using context.Services.AddSignalR
with filters:
context.Services.AddSignalR(options =>
{
options.DisableImplicitFromServicesParameters = true;
options.AddFilter<AbpHubContextAccessorHubFilter>();
options.AddFilter<AbpAuthenticationHubFilter>();
options.AddFilter<AbpAuditHubFilter>();
}).AddAzureSignalR(options =>
{
options.ConnectionString = context.Services.GetConfiguration().GetConnectionString("AzureSignalR");
options.ServerStickyMode = Microsoft.Azure.SignalR.ServerStickyMode.Required;
});
Unfortunately, neither of these resolved the issue of HttpContext
being null
when Azure SignalR is configured.
We have found two related issues with Azure SignalR disrupting the httpcontext:
Since Abp is relying on httpcontext in the BlazorServerLookupApiRequestService we either need an alternate solution to setting the headers or possibly a way to configure azure signalr so that we still have access to the httpcontext if that still is the issue.
Thank you for your assistance
We have not deployed to Azure yet, so this issue is occurring in our local development environment. Therefore, Azure-specific settings like enabling WebSockets should not be related to the problem.
Follow up, we have tried setting up azure signalr in the same way in the test project and we get the same issue there, we have tested with the filters mentioned before and without them, not solving the issue.
Hello, It seems that the issue stems from that we are using azure signalr in our Blazor Server app. When not setting up that in the Blazor module we get no httpclient null exception. We have found two possible related issues in the abp support:
https://abp.io/support/questions/2054/Using-Azure-SignalR-backplane-for-abp-Blazor-app https://abp.io/support/questions/4993/Issue-Implementing-Azure's-Managed-SignalR-service-with-an-ABP-Blazor-Server-application
We have tried using both solutions/filters when configuring azure signalr and neither solves the issue that the httpclient beeing null when trying to set the headers in the lookup api request call. Can you please check if there is any issues in how we are implementing azure signalr in the module?
public override void ConfigureServices(ServiceConfigurationContext context)
{
var hostingEnvironment = context.Services.GetHostingEnvironment();
var configuration = context.Services.GetConfiguration();
Configure<AbpSystemTextJsonSerializerOptions>(options => { options.JsonSerializerOptions.ReferenceHandler = ReferenceHandler.IgnoreCycles; });
// Add services to the container.
context.Services.AddRazorComponents()
.AddInteractiveServerComponents();
if (!configuration.GetValue<bool>("App:DisablePII"))
{
Microsoft.IdentityModel.Logging.IdentityModelEventSource.ShowPII = true;
Microsoft.IdentityModel.Logging.IdentityModelEventSource.LogCompleteSecurityArtifact = true;
}
if (!configuration.GetValue<bool>("AuthServer:RequireHttpsMetadata"))
{
Configure<OpenIddictServerAspNetCoreOptions>(options => { options.DisableTransportSecurityRequirement = true; });
Configure<ForwardedHeadersOptions>(options => { options.ForwardedHeaders = ForwardedHeaders.XForwardedProto; });
}
ConfigureAuthentication(context);
ConfigureUrls(configuration);
ConfigureBundles();
ConfigureImpersonation(context, configuration);
ConfigureCookieConsent(context);
ConfigureAutoMapper();
ConfigureVirtualFileSystem(hostingEnvironment);
ConfigureSwaggerServices(context.Services);
ConfigureAutoApiControllers();
ConfigureBlazorise(context);
ConfigureRouter(context);
ConfigureMenu(context);
ConfigureTheme();
ConfigureLocalization();
ConfigureHangfire(context, configuration);
ConfigureSignalR(context);
Configure<AbpBackgroundJobWorkerOptions>(options => { options.DefaultTimeout = 3600; });
}
private void ConfigureSignalR(ServiceConfigurationContext context)
{
context.Services.AddSignalR(options =>
{
options.AddFilter<AbpSignalRFilter>();
}).AddAzureSignalR(options =>
{
options.ConnectionString = context.Services.GetConfiguration().GetConnectionString("AzureSignalR");
options.ServerStickyMode = Microsoft.Azure.SignalR.ServerStickyMode.Required;
});
// context.Services.AddSignalR(options =>
// {
// options.AddFilter<AbpMultiTenantHubFilter>();
// }).AddAzureSignalR();
context.Services.AddResponseCompression(opts =>
{
opts.MimeTypes = ResponseCompressionDefaults.MimeTypes.Concat(
["application/octet-stream"]);
});
}
We have tried setting up signalr with the filters from both previous mentioned issues and with no filter at all. Thanks!
We are experiencing the same issue described in tickets #6195 and #8205, but the problem occurs in a Blazor Server setup running locally, not in Azure.
We have extended the IdentityUser
entity using the documented approach with an additional property called "SupplierId"
. This property is configured as a lookup using the following code:
ObjectExtensionManager.Instance.Modules()
.ConfigureIdentity(identity =>
{
identity.ConfigureUser(user =>
{
user.AddOrUpdateProperty<int?>(
"SupplierId",
property =>
{
property.UI.Lookup.Url = "/api/app/suppliers";
property.UI.Lookup.DisplayPropertyName = "companyName";
}
);
});
});
When attempting to open a modal that depends on the "SupplierId"
lookup, we encounter the following error:
System.Text.Json.JsonReaderException: '<' is an invalid start of a value.
Upon further investigation, we determined that this error is due to the response not being JSON, but instead an HTML login page (401 Unauthorized) caused by missing authentication headers during the API call.
HttpContext
) is only available during the initial page load and becomes null during subsequent SignalR WebSocket communications.HttpContextAccessor
is null when the API call is made, causing the token and authentication headers to be excluded from the request./api/app/suppliers
endpoint returns a 401 Unauthorized, leading to the parsing error.MyBlazorServerLookupApiRequestService
to try manually adding headers.HttpContextAccessor
but it was null in Blazor Server.Could you clarify how to properly handle token propagation and ensure the IdentityUser extension properties work correctly in a Blazor Server environment? Specifically:
HttpContextAccessor
?This issue seems to be directly related to how SignalR handles persistent connections in Blazor Server, and a clear resolution would be beneficial for others facing similar challenges.
Thank you for your assistance!
Hello, what do you mean by a test project?
Hi,
adding
@addTagHelper *, Microsoft.AspNetCore.Mvc.TagHelpers @addTagHelper *, Volo.Abp.AspNetCore.Mvc.UI.Bootstrap @addTagHelper *, Volo.Abp.AspNetCore.Mvc.UI.Bundling
to the Default.cshtml did the trick, thank you!
I would suggest adding this information to the section about overriding in the LeptonX Mvc Ui layout https://abp.io/docs/commercial/6.0/themes/lepton-x/commercial/mvc#account-layout
Thanks again
