• Recurso de servicios de Azure AI o Document Intelligence. Una vez que tenga la suscripción de Azure, cree un recurso de servicio único o de varios servicios en Azure AI para obtener la clave y el punto de conexión.

• Puede usar el plan de tarifa gratis (F0) para probar el servicio y actualizarlo más adelante a un plan de pago para producción.

• Una vez implementado el recurso, seleccione Ir al recurso. Necesitará la clave y el punto de conexión del recurso que ha creado para conectar la aplicación a API de Document Intelligence. En una sección posterior de este mismo inicio rápido, va a pegar la clave y el punto de conexión en el código:

Para interactuar con el servicio Document Intelligence, tiene que crear una instancia de la clase DocumentIntelligenceClient. Para ello, creará un elemento AzureKeyCredential con key de Azure Portal y una instancia de DocumentIntelligenceClient con AzureKeyCredential y el endpoint de Document Intelligence.

Para interactuar con el servicio Form Recognizer, tiene que crear una instancia de la clase DocumentAnalysisClient. Para ello, creará un elemento AzureKeyCredential con key de Azure Portal y una instancia de DocumentAnalysisClient con AzureKeyCredential y el endpoint de Form Recognizer.

Agregue el ejemplo de código siguiente al archivo Program.cs. Asegúrese de actualizar las variables de clave y punto de conexión con valores de la instancia de Document Intelligence en Azure Portal:

Ejecución de la aplicación

Tras haber agregado un ejemplo de código a la aplicación, compile y ejecute el programa:

1. Vaya a la carpeta donde tiene el archivo doc_intel_quickstart.py.

2. Escriba el siguiente comando en el terminal:

   python doc_intel_quickstart.py
   

Para analizar un archivo determinado de un URI, usará el método begin_analyze_document_from_url y transferirá prebuilt-invoice como identificador del modelo. El valor devuelto es un objeto result que contiene datos sobre el documento enviado.

Agregue el siguiente ejemplo de código a la aplicación form_recognizer_quickstart.py. Asegúrese de actualizar las variables de clave y punto de conexión con valores referentes a la instancia de Form Recognizer en Azure Portal:

# import libraries
import os
from azure.ai.formrecognizer import DocumentAnalysisClient
from azure.core.credentials import AzureKeyCredential

# set `<your-endpoint>` and `<your-key>` variables with the values from the Azure portal
endpoint = "<your-endpoint>"
key = "<your-key>"
