I am working on a .NET 8 Blazor project with .NET Identity authentication. My goal is to automatically log in the user and redirect them within the OnInitializedAsync method based on an OTP provided via a query parameter.
Here is the code snippet:
[SupplyParameterFromQuery]private string Otp { get; set; } = default!;[Inject]SignInManager<ApplicationUser> SignInManager { get; set; } = default!;protected override async Task OnInitializedAsync(){ try { if (HttpMethods.IsGet(HttpContext.Request.Method)) { await HttpContext.SignOutAsync(IdentityConstants.ExternalScheme); } if (!string.IsNullOrEmpty(Otp)) { // Validate and get the user and claims await SignInManager.SignInWithClaimsAsync(user, isPersistent: false, claims); NavigationManager.NavigateTo("/test"); } else { NavigationManager.NavigateTo("/error"); } await base.OnInitializedAsync(); } catch (Exception) { NavigationManager.NavigateTo("/error"); }}However, when attempting to redirect the user, I am encountering the following exception:
Microsoft.AspNetCore.Components.NavigationException: 'Exception of type 'Microsoft.AspNetCore.Components.NavigationException' was thrown.'How can I handle this exception or modify my approach to achieve the desired functionality without encountering errors?
UpdateThis worked for me
public static class BlazorSsrRedirectManagerExtensions{ public static void RedirectTo(this HttpContext httpContext, string redirectionUrl) { ArgumentNullException.ThrowIfNull(httpContext); httpContext.Response.Headers.Append("blazor-enhanced-nav-redirect-location", redirectionUrl); httpContext.Response.StatusCode = 200; httpContext.Response.Redirect(redirectionUrl); }}
