在program.cs中添加以下代码
var builder = WebApplication.CreateBuilder(args);
builder.Services.AddCors(options =>
{
options.AddPolicy("AllowAllOrigins",
builder =>
{
builder
.AllowAnyMethod()
.SetIsOriginAllowed(_ => true)
.AllowAnyHeader()
.AllowCredentials();
});
});
var app = builder.Build();
app.UseCors("AllowAllOrigins");
