Give Blazor SSR access to HTTP Context

[westonwalker]

Is there an existing issue for this?

• I have searched the existing issues

Is your feature request related to a problem? Please describe the problem.

Currently Blazor SSR components do not have access to HTTP Context. So login and register pages have to be created using Razor Pages.

However, if using the Blazor enhanced navigation, switching between Blazor and Razor Page routes causes styling issues due to them using different layouts.

Describe the solution you'd like

I would like to Blazor SSR components to have access to the HTTP Context object. This would solve the above issue and allow us to entirely create apps with authentication in Blazor.

@westonwalker You should be able to obtain an instance for server-side rendered components by injecting IHttpContextAccessor into your component.

It will of course not work for Server with SignalR since there are no requests, hence no HttpContext.

Program.cs:

builder.Services.AddHttpContextAccessor();

In your component (.razor):

@inject IHttpContextAccessor HttpContextAccessor

Obtain the current HttpContext:

var httpContext = HttpContextAccessor.HttpContext;

@westonwalker And I want to add, unless you really want to re-invent everything yourself, you can use what is already in ASP.NET Core to do authentication, and even register users. For Blazor SSR works the same way as with Razor Pages.

There will be official ones, but I myself ported some of the Razor Pages to Razor components:

I use cookie authentication both for SSR and interactive client components.

This is a dupe of #48769, which is now done.

Thanks for the advice @marinasundstrom . I'll do that until the .NET 8 RC adds Httpcontext access.
