Cors在.Net Core 3.1项目中实现Oracle数据库主机

Question

Only one HOST can connect to the API, in this case it is an Oracle server.

I added Cors as per Microsoft docs, still other HOST can connect to my API. Has anyone tried to add an Oracle Database HOST? Is there something wrong with the configuration?

Startup.cs

public void ConfigureServices(IServiceCollection services)
        {
            services.AddControllers();
            services.AddHttpClient();

            services.AddCors(options =>
            {
                options.AddPolicy(name: "CorsPolicy",
                    builder =>
                    {
                        builder.WithOrigins("http://oraas1111.net:1001")
                                           .AllowAnyHeader()
                                           .AllowAnyMethod();
                    });
            });
        } 
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
        {
            if (env.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
            }
            app.UseRouting();

            app.UseCors("CorsPolicy");

            app.UseAuthorization();

            app.UseEndpoints(endpoints =>
            {
                endpoints.MapControllers().RequireCors("CorsPolicy");
            });
        }

Controller.cs

    [EnableCors("CorsPolicy")]
    [Route("[controller]")]
    [ApiController]
    public class Controller : ControllerBase
    {

        [HttpPost]
        [Route("/Service/[action]")]
        public async Task<ActionResult<Request>> Update(Request data)
        {

        }

        [HttpGet]
        [Route("/GET_Service/[action]")]
        public ActionResult Test()
        {
            return Ok();
        }
    }

You have to move services.AddCors() to the top, before AddControllers()
