Crea evaluaciones destinadas a aplicaciones para dispositivos móviles

En esta página, se explica cómo crear una evaluación para permitir que tu backend verifique la autenticidad del token que envía reCAPTCHA Enterprise. reCAPTCHA Enterprise envía una respuesta encriptada, el token de respuesta (token) de reCAPTCHA, cuando el usuario final activa una acción.

Debes crear una evaluación para evaluar los resultados de execute() en tu backend. Para ello, envía el token generado al extremo de la evaluación. reCAPTCHA Enterprise procesa el token enviado y, luego, informa la validez y puntuación del token.

El primer millón de evaluaciones mensuales de reCAPTCHA Enterprise son gratuitas. Para seguir creando evaluaciones después de alcanzar el límite de uso mensual gratuito (1 millón de evaluaciones al mes), debes habilitar la facturación para tu proyecto de Google Cloud. Para obtener más información sobre la facturación de reCAPTCHA Enterprise, consulta Datos de facturación.

Antes de comenzar

  1. Prepara tu entorno para reCAPTCHA Enterprise.
  2. Asegúrate de tener el siguiente rol de Identity and Access Management: Agente de reCAPTCHA Enterprise (roles/recaptchaenterprise.agent).
  3. Instala claves basadas en puntuaciones en tu aplicación para iOS o en tu aplicación para Android.
  4. Configura la autenticación en reCAPTCHA Enterprise.

    El método de autenticación que elijas dependerá del entorno en el que se haya configurado reCAPTCHA Enterprise. En la siguiente tabla, encontrarás ayuda para elegir el método de autenticación apropiado y la interfaz compatible para configurar la autenticación:

    Entorno Interfaz Método de autenticación
    Google Cloud
    • REST
    • Bibliotecas cliente
    Usa cuentas de servicio adjuntas.
    Local o un proveedor de servicios en la nube diferente REST Usa claves de API o la federación de identidades para cargas de trabajo.

    Si deseas usar claves de API, te recomendamos que apliques restricciones de claves de API para protegerlas.

    Bibliotecas cliente

    Para ello, usa los siguientes recursos:

Recupera un token

Recupera un token de la respuesta de la llamada a execute().

Puedes acceder al token de cada usuario solo una vez. Si necesitas evaluar una acción posterior que realiza un usuario en tu aplicación para dispositivos móviles, o si un token vence antes de que se cree una evaluación, debes volver a llamar a execute() para generar un token nuevo.

Crea una evaluación

Después de configurar la autenticación, crea una evaluación. Para ello, envía una solicitud a la API de reCAPTCHA Enterprise o usa las bibliotecas cliente de reCAPTCHA Enterprise.

Para mejorar la detección, te recomendamos que pases los siguientes valores adicionales cuando crees evaluaciones: userAgent, userIpAddress y ja3.

API de REST

Para crear una evaluación, envía una solicitud a la API de reCAPTCHA Enterprise. Puedes usar gcloud CLI o la clave de API para la autenticación.

Usa la CLI de gcloud

Crea una evaluación con el método projects.assessments.create. Envía esta solicitud al extremo de API de v1.

Antes de usar cualquiera de los datos de solicitud a continuación, realiza los siguientes reemplazos:

  • PROJECT_ID: El ID del proyecto de Google Cloud.
  • TOKEN: Token que se muestra a partir de la llamada grecaptcha.enterprise.execute()
  • KEY_ID: Es la clave reCAPTCHA asociada con el sitio o la app. Para obtener más información, consulta las claves de reCAPTCHA.
  • USER_AGENT: Es el usuario-agente de la solicitud del dispositivo del usuario.
  • USER_IP_ADDRESS: Es la dirección IP en la solicitud del dispositivo del usuario.
  • JA3: Huella digital JA3 para el cliente SSL. Recomendamos usar salesforce/ja3 para procesar JA3.
  • USER_ACTION: Es la acción iniciada por el usuario que especificaste para action en la llamada a grecaptcha.enterprise.execute(), como login.

    Para obtener más información, consulta Nombres de acciones.

HTTP method and URL:

POST https://recaptchaenterprise.googleapis.com/v1/projects/PROJECT_ID/assessments

Cuerpo JSON de la solicitud:

{
  "event": {
    "token": "TOKEN",
    "siteKey": "KEY_ID",
    "userAgent": "USER_AGENT",
    "userIpAddress": "USER_IP_ADDRESS",
    "ja3": "JA3",
    "expectedAction": "USER_ACTION"
  }
}

Para enviar tu solicitud, elige una de estas opciones:

curl

Guarda el cuerpo de la solicitud en un archivo llamado request.json y ejecuta el siguiente comando:

curl -X POST \
-H "Authorization: Bearer $(gcloud auth print-access-token)" \
-H "Content-Type: application/json; charset=utf-8" \
-d @request.json \
"https://recaptchaenterprise.googleapis.com/v1/projects/PROJECT_ID/assessments"

PowerShell

Guarda el cuerpo de la solicitud en un archivo llamado request.json y ejecuta el siguiente comando:
