CORS 구성 - ASP 네트 코어

CORS 구성

API와 API 간의 상호 작용에 대한 정의, API 사용에 대한 요구 사항은 WS와 상호 작용할 수 있습니다. CORS 구성에 대한 정의입니다.

Esta configuración se realiza en la clase **Startup** .

Declaras una variable solo de lectura, al inicio de la clase:

public class Startup
{
    readonly string MiCors = "MiCors";
        ...
        ...
}

Lo siguiente, es agregar la configuración del servicio en el metodo **ConfigureServices** :

services.AddCors(options =>
{
      options.AddPolicy(name: MiCors,
                        builder =>
                        {
                                builder.WithMethods("*");
                                builder.WithHeaders("*");
                            builder.WithOrigins("*");
                        });
});

**builder.WithOrigins("*"); -** Es donde se le indica al CORS qué dirección tendrá interacción con el WS. Si se deja el asterisco como tal, permitirá la conexión de cualquier dirección.

Por último es necesario agregar el **app.Use** , 최종 결정 사항:

app.UseRouting();

app.UseCors(MiCors);

app.UseAuthorization();
