路径不是来自Blazor的允许的IdentityServer CORS端点，但可用于邮递员

Question

在单独的项目中具有IdentityServer4和Blazor客户端的Identity用户数据库API。我可以通过邮递员注册一个新用户。在Blazor客户端中运行以下代码时（用于修补和学习）

@page "/registrer"
@using Models
@using System.Net.Http
@using IdentityModel.Client
@inject HttpClient Http

    <EditForm Model="@registerUserModel" OnValidSubmit="@HandleValidSubmit">
        <DataAnnotationsValidator />
        <ValidationSummary />

        <InputText id="email" type="email" @bind-Value="@registerUserModel.Email" />
        <InputText id="password" type="password" @bind-Value="@registerUserModel.Password" />
        <InputText id="confirmPassword" type="password" @bind-Value="@registerUserModel.ConfirmPassword" />

        <button type="submit">Registrer deg</button>
    </EditForm>

@code {
    private RegisterUserModel registerUserModel = new RegisterUserModel();

    public async Task HandleValidSubmit()
    {
        var newUser = new RegisterUserModel
        {
            Email = registerUserModel.Email,
            Password = registerUserModel.Password,
            ConfirmPassword = registerUserModel.ConfirmPassword
        };

        var client = new HttpClient();

        var response = await client.RequestClientCredentialsTokenAsync(new ClientCredentialsTokenRequest
        {
            Address = "https://localhost:5001/connect/token",

            ClientId = "client",
            ClientSecret = "511536EF-F270-4058-80CA-1C89C192F69A",
            Scope = "api1"
        });

        Http.SetBearerToken(response.AccessToken);

        await Http.PostJsonAsync("https://localhost:5001/register", newUser);
    }
}

我能够获取访问令牌并验证Blazor客户端，但随后出现此错误

dbug：IdentityServer4.Hosting.CorsPolicyProvider [0]针对来源：http://localhost:60013的路径：/注册提出了CORS请求，但由于路径不是针对允许的IdentityServer CORS端点

为什么？当它在邮递员中工作并且没有CORS政策时。试图允许客户使用AllowedCorsOrigins，只是为了检查。

编辑：HttpClient的两个实例只是“修补”，我知道（？）注入的客户端具有某种默认值，但是当在@code中使用新的默认值时，错误保持不变

ID4配置按要求

                new Client
                {
                    ClientId = "client",
                    ClientName = "Client Credentials Client",

                    AllowedGrantTypes = GrantTypes.ClientCredentials,
                    ClientSecrets = { new Secret("511536EF-F270-4058-80CA-1C89C192F69A".Sha256()) },

                    AllowedScopes = { "api1" },
                    // AllowedCorsOrigins = { "http://localhost:60013" },
                },
ID4启动

        var builder = services.AddIdentityServer(options =>
        {
            options.Events.RaiseErrorEvents = true;
            options.Events.RaiseInformationEvents = true;
            options.Events.RaiseFailureEvents = true;
            options.Events.RaiseSuccessEvents = true;
        })
        .AddInMemoryIdentityResources(Config.GetIdentityResources())
        .AddInMemoryApiResources(Config.GetApis())
        .AddInMemoryClients(Config.GetClients())
        .AddAspNetIdentity<User>();

        builder.AddDeveloperSigningCredential();
