## Verifique o usuário { #check-the-username }

Aqui está um exemplo mais completo.

Utilize uma dependência para verificar se o usuário e a senha estão corretos.

Para isso, utilize o módulo padrão do Python <a href="https://docs.python.org/3/library/secrets.html" class="external-link" target="_blank">`secrets`</a> para verificar o usuário e senha.

        int expectedBytes = 12 + (fileName.length() * 2); // Unicode is 2 bytes per char
        assertEquals(expectedBytes, bytesRead);
    }

    @DisplayName("Test getAction returns correct value")
    void testGetAction() throws SMBProtocolDecodingException {
        int expectedAction = FileNotifyInformation.FILE_ACTION_RENAMED_NEW_NAME;

            // Act
            String result = uuid.toString();

            // Assert
            assertEquals(VALID_UUID_STRING, result.toUpperCase(), "toString() should return the correct UUID string in uppercase");

Puedes usar funciones `async` o regulares.

**FastAPI** hará lo correcto con cada una, igual que con dependencias normales.

La manera en que los formularios HTML (`<form></form>`) envían los datos al servidor normalmente usa una codificación "especial" para esos datos, es diferente de JSON.

**FastAPI** se encargará de leer esos datos del lugar correcto en lugar de JSON.

/// note | Detalles técnicos

Los datos de formularios normalmente se codifican usando el "media type" `application/x-www-form-urlencoded`.
