En muchos casos no es muy obvio cómo las variables de entorno serían útiles y aplicables de inmediato. Pero siguen apareciendo en muchos escenarios diferentes cuando estás desarrollando, así que es bueno conocerlas.

### Suporte do OpenAPI

O OpenAPI não suporta uma maneira de declarar um *parâmetro de rota* que contenha uma *rota* dentro, dado que isso poderia levar a cenários que são difíceis de testar e definir.

No entanto, você pode fazer isso no **FastAPI**, usando uma das ferramentas internas do Starlette.

Probablemente no necesitarás usarlos directamente en tu código.

Pero en caso de que los necesites para un escenario avanzado, puedes agregar headers personalizados:

{* ../../docs_src/handling_errors/tutorial002.py hl[14] *}

## Instalar manejadores de excepciones personalizados

## Before Upgrading

Consider the following changes, limitations, and guidelines before you upgrade:

### **API Machinery**

                            } catch (SmbException e) {
                                // Account locked out - this is expected behavior in concurrent scenario
                                blockedAttempts.incrementAndGet();
                                break; // Stop trying if account is locked
                            }

                            if (!allowed) {

You probably won't need to use it directly in your code.

But in case you needed it for an advanced scenario, you can add custom headers:

{* ../../docs_src/handling_errors/tutorial002.py hl[14] *}
