Hi Support Teams,
I have two questions:
- Is there a way to use ScreenUrl within ExtraProperties instead of creating an additional ScreenUrl column and using EF.Property(u, "ScreenUrl") to write the query statement?
Below is my code.
2. How can I add `context.GetHttpContext().Request.Headers["screen-url"]` to the `ScreenUrl` column in `EntityChanges`? Currently, when I run it, it only adds it to the `ScreenUrl` in `ExtraProperties` but doesn't save it to the newly added `ScreenUrl` column.
public class ExtendedAuditLogContributor : AuditLogContributor
{
public override void PreContribute(AuditLogContributionContext context)
{
context.AuditInfo.SetProperty(
"ScreenUrl",
context.GetHttpContext().Request.Headers["screen-url"]
);
}
public override void PostContribute(AuditLogContributionContext context)
{
var currentUser = context.ServiceProvider.GetRequiredService<ICurrentUser>();
foreach (var change in context.AuditInfo.EntityChanges)
{
change.SetProperty(
"ScreenUrl",
context.GetHttpContext().Request.Headers["screen-url"]);
change.SetProperty(
"UserId", currentUser.Id);
}
}
}

Hi,
Is there a way to use ScreenUrl within ExtraProperties instead of creating an additional ScreenUrl column and using EF.Property(u, "ScreenUrl") to write the query statement?
Unfortunately no, It will be calculated on the client side instead of the server client, which will affect query performance: https://learn.microsoft.com/en-us/ef/core/querying/client-eval
How can I add
context.GetHttpContext().Request.Headers["screen-url"]to theScreenUrlcolumn inEntityChanges? Currently, when I run it, it only adds it to theScreenUrlinExtraPropertiesbut doesn't save it to the newly addedScreenUrlcolumn.Could you share a simple minimal project to reproduce the problem? I will check it, thanks. my email is shiwei.liang@volosoft.com

Hi,
I made some changes to the project and it works for me.
I have shared the project with you via email, you can check it
Steps
- Run
dotnet ef database updateto create database. (for authserver and httpapihost) - Run the AuthServer, HttpApi.Host and Blazor project
- Login and navigate to
commonpage - Click the

It worked. Thank you very much.
But I'm still facing an issue. Currently, in Blazor WebAssembly, I have code in
HttpApi.Client.
and I use
context.GetHttpContext().Request.Headers["screen-url"].ToString();to get the URL.
However, using this approach won't work in Blazor Server. Is there any way to retrieve the URL when using Blazor Server?

Is the Blazor server a tiered solution?

I think it should be working.
How I reproduce the problem? I will check it.

Here is the result when running Blazor WebAssembly.
When I run Blazor Server, I am unable to find the Screen-Url, and there is no data for Screen-Url being saved in the AuditLogs and EntityChange database tables.

You can try:
public class MyHubFilter : IHubFilter { public ValueTask<object?> InvokeMethodAsync(HubInvocationContext invocationContext, Func<HubInvocationContext, ValueTask<object?>> next) { var httpContext = invocationContext.Context.GetHttpContext(); if (httpContext != null) { var navigationManager = invocationContext.ServiceProvider.GetRequiredService<NavigationManager>(); httpContext.Request.Headers["screen-url"] = navigationManager.Uri; } return next(invocationContext); } } public override void PreConfigureServices(ServiceConfigurationContext context) { Configure<HubOptions>(options => { options.AddFilter<MyHubFilter>(); }); }Markdown supported.Copy, paste, or drag & drop images and files (max 100 MB per file, 100 MB total per post) -

Please add to the Blazor server instead of HttpAPI project

You did not configure the
AuditMessageHandler

I apologize for the delayed response. Do I need to make any modifications to the AuditMessageHandler?
Because when I configure the AuditMessageHandler, I encounter an error when running it:

Hi,
Yes you need to make some changes
Idea from: https://stackoverflow.com/questions/77129117/blazor-navigationmanager-not-initialized-error
Add
AppInfoclass to Blazor server project.public class AppInfo : ISingletonDependency { public string? CurrentUrl { get; private set; } public void UpdateAppUrl(string url) { this.CurrentUrl = url; } }Move
AuditMessageHandlerclass to Blazor Server projectpublic class AuditMessageHandler : DelegatingHandler, ITransientDependency { private readonly AppInfo _appInfo; public AuditMessageHandler(AppInfo appInfo) { _appInfo = appInfo; } protected override Task<HttpResponseMessage> SendAsync(HttpRequestMessage request, CancellationToken cancellationToken) { request.Headers.Add("screen-url", _appInfo.CurrentUrl); return base.SendAsync(request, cancellationToken); } }Add
AppInfoProvider.razorto Blazor server project.@code { [Inject] private NavigationManager NavigationManager { get; set; } = default!; [Inject] private AppInfo AppInfo { get; set; } = default!; protected override void OnInitialized() { NavigationManager.LocationChanged += (sender, args) => { this.AppInfo.UpdateAppUrl(this.NavigationManager.Uri); }; } } ------------------- Configure<AbpLayoutHookOptions>(options => { options.Add(LayoutHooks.Body.First, typeof(AppInfoProvider),StandardLayouts.Application); });Markdown supported.Copy, paste, or drag & drop images and files (max 100 MB per file, 100 MB total per post)
