Azure B2C与Blazor Web App集成技术指导求助

问题描述 #

我们正尝试将Azure B2C与Blazor Web App集成，虽有官方通用指导文档但仍未找到解决方案。通过Visual Studio创建Blazor Server App时集成该功能很简单，但新版Blazor Web App仅提供个人登录选项。

我们已尝试遵循官方文档指导但无效，运行时出现错误：An action cannot use both form and JSON body parameters.

当前program.cs代码如下：

using AzureB2CTesting2.Components;
using AzureB2CTesting2.Components.Account;
using AzureB2CTesting2.Data;
using Microsoft.AspNetCore.Authentication.OpenIdConnect;
using Microsoft.AspNetCore.Components.Authorization;
using Microsoft.AspNetCore.Identity;
using Microsoft.EntityFrameworkCore;
using Microsoft.Identity.Web;
using Microsoft.Identity.Web.UI;

var builder = WebApplication.CreateBuilder(args);


// Add configuration to the container
builder.Configuration.AddJsonFile("appsettings.json"); // Adjust the file path as needed


// Add services to the container.
builder.Services.AddRazorComponents()
    .AddInteractiveServerComponents();

builder.Services.AddCascadingAuthenticationState();
//builder.Services.AddScoped<IdentityUserAccessor>();
builder.Services.AddScoped<IdentityRedirectManager>();
builder.Services.AddScoped<AuthenticationStateProvider, IdentityRevalidatingAuthenticationStateProvider>();

builder.Services.AddMicrosoftIdentityWebAppAuthentication(builder.Configuration, "AzureB2C");

builder.Services.AddControllersWithViews()
    .AddMicrosoftIdentityUI();

builder.Services.AddRazorPages();

//Configuring appsettings section AzureAdB2C, into IOptions
builder.Services.AddOptions();
builder.Services.Configure<OpenIdConnectOptions>(builder.Configuration.GetSection("AzureB2C"));

IdentityNoOpEmailSender>();

var app = builder.Build();

// Configure the HTTP request pipeline.
if (app.Environment.IsDevelopment())
{
    app.UseMigrationsEndPoint();
}
else
{
    app.UseExceptionHandler("/Error", createScopeForErrors: true);
    // The default HSTS value is 30 days. You may want to change this for production scenarios, see https://aka.ms/aspnetcore-hsts.
    app.UseHsts();
}

app.UseAuthentication();
app.UseAuthorization();

app.UseHttpsRedirection();

app.UseStaticFiles();
app.UseAntiforgery();

app.MapRazorComponents<App>()
    .AddInteractiveServerRenderMode();

// Add additional endpoints required by the Identity /Account Razor components.
app.MapAdditionalIdentityEndpoints();

app.Run();

更新内容 #

我们创建了一个使用Azure B2C的Blazor Server App，然后按照官方迁移文档将其转换为Blazor Web App，只需确保App.razor和Routes.razor文件位于根目录即可。
