概述

To successfully establish a connection and send requests to the Form Recognizer API, the Azure Form Recognizer Scope activity must provide a subscription key that validates your subscription to the Azure Form Recognizer service.

要生成订阅密钥并使其他活动能够成功向表单识别器 API 操作发送请求，您必须完成以下先决条件和步骤：

1. 创建表单识别器 Azure 资源

2. 构建并上传训练数据集

3. 获取共享访问签名

4. 构建项目

   

1. Create a Form Recognizer Azure resource

Complete Microsoft's documented steps to create a Form Recognizer resource.

备注：

The Azure Form Recognizer service is available in a limited-access preview. Because of this, the process to create a resource may be different when compared to other Azure services (to learn more, see request access in the Microsoft documentation).

当表单识别器资源完成部署时：

1. Find and select it from the All resources list in the portal.

2. Click the Quick start tab under RESOURCE MANAGEMENT to view your subscription data.

3. 备注：

   the values of Key1 and Endpoint (you'll enter these in the Azure Form Recognizer Scope activity).

   

2. Build and upload a training data set

Follow Microsoft's documented tips and input requirements to build a training data set for a custom model.

备注：

To build a training data set for our examples, we used the files in the Train folder of Microsoft's provided sample data set.

After building your training data set, follow Microsoft's documented steps to create a container (you may need to create a storage account first if you don't have one).

创建容器后：

1. Go to Storage Explorer in the Azure portal.

2. Under Subscriptions, find and select the storage account that you created your container in.

3. Under the account's Blob containers, select the container that you created.

4. Upload your training data set (e.g., 5 PDF invoices).

   

3. Get shared access signature

The Train Model activity requires a URI to the container that has your training data set.

要获取容器 URI，请执行以下操作：

1. Go to Storage Explorer in the Azure portal.

2. Under Subscriptions, find and select the storage account that you created your container in.

3. Under the account's Blob containers, right-click the container that you created.

4. Click Get Shared Access Signature (this opens Shared Access Signature window).

5. Enter your Access policy,Start time,Expiry time,Time zone, and Permissions.

   • At a minimum, select *Read
   • and *List
   • from the Permissions list.

6. 单击“创建”。

7. 备注：

   the URI value.

   

4. 构建项目

1. 创建一个新的自动化项目。

   1. Open UiPath Studio.

   2. Under New Project, click Process (this opens a New Blank Process window).

   3. Enter a project Name, Location, and Description.

   4. 单击“创建”。

      

2. Install the UiPath.AzureFormRecognizer.Activities package.
   1. In the Design ribbon, click Manage Packages (this opens the Manage Packages window).
   2. Under All Packages, click Go.
   3. In the Search bar, enter Azure.
   4. Click, install and accept the license for the UiPath.AzureFormRecognizer.Activities.

      • For more information about Uipath Studio packages, see Managing Packages in the Studio Guide.

        

操作完毕！

现在，您已完成设置，可以开始将 Azure 表单识别器活动添加到项目中。
