小编Dis*_*ort的帖子

我第一次尝试使用 MSAL 授权，但在 Blazor 中失败了。任何线索（我认为这将是一个简单的答案？）

此处提供小型仓库

客户端文件：Program.cs

var builder = WebAssemblyHostBuilder.CreateDefault(args);
builder.RootComponents.Add<App>("app");

builder.Services.AddMsalAuthentication(options => //THROWS EXCEPTION!!!!!
{
    options.ProviderOptions.AdditionalScopesToConsent.Add($"https://graph.microsoft.com/User.Read");
});

var baseAddress = builder.HostEnvironment.BaseAddress;
builder.Services.AddHttpClient(baseAddress, client => client.BaseAddress = new Uri(baseAddress))
        .AddHttpMessageHandler<BaseAddressAuthorizationMessageHandler>();

意外结果：抛出异常

暴击：
