• Служба ИИ Azure или ресурс аналитики документов. После получения подписки Azure создайте ресурс с несколькими службами или azure AI в портал Azure, чтобы получить ключ и конечную точку.

• Используйте бесплатную ценовую категорию (F0), чтобы опробовать службу, а затем выполните обновление до платного уровня для рабочей среды.

• После развертывания ресурса выберите Перейти к ресурсу. Вам потребуется ключ и конечная точка из ресурса, создаваемого для подключения приложения к API аналитики документов. Вставьте ключ и конечную точку в код далее в кратком руководстве:

Чтобы взаимодействовать со службой аналитики DocumentIntelligenceClient документов, необходимо создать экземпляр класса. Для этого вы создадите AzureKeyCredential с key помощью портал Azure и DocumentIntelligenceClient экземпляра с AzureKeyCredential помощью аналитики документовendpoint.

Чтобы взаимодействовать со службой Распознаватель документов, необходимо создать экземпляр DocumentAnalysisClient класса. Для этого вы создадите AzureKeyCredential с key портал Azure и DocumentAnalysisClient экземпляром с AzureKeyCredential Распознаватель документовendpoint.

Запуск приложения

После добавления примера кода в приложение создайте и запустите программу:

1. Перейдите в папку, в которой есть файл doc_intel_quickstart.py .

2. В окне терминала введите следующую команду:

   python doc_intel_quickstart.py
   

Чтобы проанализировать заданный файл по универсальному коду ресурса, используйте метод begin_analyze_document_from_url и передайте prebuilt-layout в качестве идентификатора модели. Возвращаемое значение — это объект result, содержащий данные об отправленном документе.

Запуск приложения

После добавления примера кода в приложение создайте и запустите программу:

1. Перейдите в папку, в которой есть файл doc_intel_quickstart.py .

2. В окне терминала введите следующую команду:

   python doc_intel_quickstart.py
   

Чтобы проанализировать заданный файл по универсальному коду ресурса, используйте метод begin_analyze_document_from_url и передайте prebuilt-invoice в качестве идентификатора модели. Возвращаемое значение — это объект result, содержащий данные об отправленном документе.

Добавьте приведенный ниже пример кода в свое приложение form_recognizer_quickstart.py. Убедитесь, что ключи и переменные конечной точки обновлены значениями из экземпляра Распознавателя документов на портале Azure:

# 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>"
