authentication - 使用多个身份提供者对 Blazor WebAssembly 进行身份验证

Question

我正在学习 Blazor WebAssembly 并构建一个小项目，以在 Azure 中作为静态 Web 应用程序托管。

目标框架是net5.0。

当用户单击“登录”超链接或按钮时，新页面将显示一些身份提供者的名称（Microsoft、Google、SackOverflow 等）。然后用户将选择一个进行登录。

我只使用了一个身份提供者（只是微软、谷歌等）。

如何在同一个应用程序中使用多个身份提供者？

有人可以帮助我吗？

Blazor WebAssembly 应用程序

目标框架：net5.0

在 Azure 中作为静态 Web 应用程序托管

程序.cs

using Blazored.LocalStorage;

using Microsoft.AspNetCore.Components.WebAssembly.Hosting;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;

using System;
using System.Net.Http;
using System.Threading.Tasks;

namespace FileProcApp
{
    public class Program
    {
        public static async Task Main(string[] args) {
            var builder = WebAssemblyHostBuilder.CreateDefault(args);
            builder.RootComponents.Add<App>("#app");

            builder.Services.AddScoped(sp => new HttpClient { BaseAddress = new Uri(builder.HostEnvironment.BaseAddress) });

            builder.Services.AddOidcAuthentication(options => {
                options.ProviderOptions.DefaultScopes.Clear();
                options.ProviderOptions.DefaultScopes.Add("openid");
                options.ProviderOptions.DefaultScopes.Add("offline_access");
                builder.Configuration.Bind("AzureAd", options.ProviderOptions);
            });
            
            builder.Services.AddOidcAuthentication(options => {
                options.ProviderOptions.DefaultScopes.Clear();               
                builder.Configuration.Bind("Google", options.ProviderOptions);
            });


            builder.Services.AddBlazoredLocalStorage();

            builder.Services.AddSingleton<Services.Authentication>();

            await builder.Build().RunAsync();
        }
    }
}

应用设置.json

  "Google": {
    "Authority": "https://accounts.google.com/",
    "ClientId": "1234567890123-45678901234567890123456789012345.apps.googleusercontent.com",
    "PostLogoutRedirectUri": "https://lorem-ipsun-dolor-sit-amet.azurestaticapps.net/authentication/logout-callback",
    "RedirectUri": "https://lorem-ipsun-dolor-sit-amet.azurestaticapps.net/authentication/login-callback",
    "ResponseType": "token id_token"
  },
  "AzureAd": {
    "Authority": "https://login.microsoftonline.com/common",
    "ClientId": "12345678-9012-3456-7890-123456789012",
    "ValidateAuthority": true
  }
}
