如何配置cors以使swagger.json可以从另一个来源消费来构建.net blazor文档门户网站

我有一个.net核心7 api(WebApplication1)和一个blazor应用程序(BlazorApp1)。api和blazor应用程序已经安装了swagger,我想使用blazor程序中的swagger/swagger.json在iframe中显示swagger ui。然而,我不知道如何配置api,这样我就不会出现cors错误。

这是我的WebApplication1/Program.cs

WebApplication1/Program.cs
var builder = WebApplication.CreateBuilder(args);

var  myAllowSpecificOrigins = "_myAllowSpecificOrigins";
builder.Services.AddCors(options =>
{
    options.AddPolicy(name: myAllowSpecificOrigins,
        policy  =>
        {
            policy
                .AllowAnyOrigin()
                .AllowAnyMethod()
                .AllowAnyHeader();
        });
});
// Add services to the container.

builder.Services.AddControllers();
// Learn more about configuring Swagger/OpenAPI at https://aka.ms/aspnetcore/swashbuckle
builder.Services.AddEndpointsApiExplorer();
builder.Services.AddSwaggerGen();

var app = builder.Build();

// Configure the HTTP request pipeline.
if (app.Environment.IsDevelopment())
{
    app.UseSwagger();
    app.UseSwaggerUI();
}

app.UseHttpsRedirection();
app.UseRouting();
app.UseCors(myAllowSpecificOrigins);
app.UseAuthorization();

app.MapControllers();

app.Run();

这是我的BlazorApp1/Program.cs

//BlazorApp1/Program.cs
using BlazorApp1.Data;

var builder = WebApplication.CreateBuilder(args);


// Add services to the container.
builder.Services.AddRazorPages();
builder.Services.AddServerSideBlazor();
builder.Services.AddSingleton<WeatherForecastService>();
builder.Services.AddControllers();
builder.Services.AddSwaggerGen();
var app = builder.Build();

// Configure the HTTP request pipeline.
if (!app.Environment.IsDevelopment())
{
    app.UseExceptionHandler("/Error");
    // 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.UseSwagger();
app.UseSwaggerUI(options => options.SwaggerEndpoint("https://localhost:44323/swagger/v1/swagger.json","v1"));

app.UseHttpsRedirection();

app.UseStaticFiles();

app.UseRouting();

app.MapBlazorHub();
app.MapFallbackToPage("/_Host");

app.Run();

WebApplication1正在上运行https://localhost:44323 BlazorApp1正在上运行https://localhost:7145

无论我如何调整api中的cors配置,我都会得到以下结果:
