DocumentModelAdministrationClient class

  • 参考
包:
@azure/ai-form-recognizer

用于与 表单识别器 服务的模型管理功能交互的客户端，例如创建、读取、列出、删除和复制模型。

示例：

Azure Active Directory

import { DocumentModelAdministrationClient } from "@azure/ai-form-recognizer";
import { DefaultAzureCredential } from "@azure/identity";

const endpoint = "https://<resource name>.cognitiveservices.azure.com";
const credential = new DefaultAzureCredential();

const client = new DocumentModelAdministrationClient(endpoint, credential);

API 密钥 (订阅密钥) 

import { DocumentModelAdministrationClient, AzureKeyCredential } from "@azure/ai-form-recognizer";

const endpoint = "https://<resource name>.cognitiveservices.azure.com";
const credential = new AzureKeyCredential("<api key>");

const client = new DocumentModelAdministrationClient(endpoint, credential);

构造函数

DocumentModelAdministrationClient(string, KeyCredential, DocumentModelAdministrationClientOptions)

从资源终结点和静态 API 密钥创建 DocumentModelAdministrationClient 实例， () KeyCredential ，

示例：

import { DocumentModelAdministrationClient, AzureKeyCredential } from "@azure/ai-form-recognizer";

const endpoint = "https://<resource name>.cognitiveservices.azure.com";
const credential = new AzureKeyCredential("<api key>");

const client = new DocumentModelAdministrationClient(endpoint, credential);
DocumentModelAdministrationClient(string, TokenCredential, DocumentModelAdministrationClientOptions)

从资源终结点和 Azure 标识 TokenCredential创建 DocumentModelAdministrationClient 实例。

有关使用 Azure Active Directory 进行身份验证的详细信息， @azure/identity 请参阅包。

示例：

import { DocumentModelAdministrationClient } from "@azure/ai-form-recognizer";
import { DefaultAzureCredential } from "@azure/identity";

const endpoint = "https://<resource name>.cognitiveservices.azure.com";
const credential = new DefaultAzureCredential();

const client = new DocumentModelAdministrationClient(endpoint, credential);

方法

beginBuildDocumentClassifier(string, DocumentClassifierDocumentTypeSources, BeginBuildDocumentClassifierOptions)

使用给定的分类器 ID 和文档类型生成新的文档分类器。

分类器 ID 在资源中的分类器中必须是唯一的。

文档类型作为对象提供，该对象将文档类型的名称映射到该文档类型的训练数据集。 支持两种训练数据输入方法：

  • azureBlobSource，它使用给定Azure Blob 存储容器中的数据训练分类器。
  • azureBlobFileListSource，它类似于 azureBlobSource ，但允许使用 JSONL 格式的文件列表对训练数据集中包含的文件进行更精细的控制。

表单识别器服务从 Azure 存储容器读取训练数据集，该数据集作为包含 SAS 令牌的容器的 URL 提供，允许服务后端与容器通信。 至少需要“读取”和“列表”权限。 此外，必须根据特定约定组织给定容器中的数据，该约定记录在 用于生成自定义文档分类器的服务文档中。

示例

const classifierId = "aNewClassifier";
const containerUrl1 = "<training data container SAS URL 1>";
const containerUrl2 = "<training data container SAS URL 2>";

const poller = await client.beginBuildDocumentClassifier(
  classifierId,
  {
    // The document types. Each entry in this object should map a document type name to a
    // `ClassifierDocumentTypeDetails` object
    "formX": {
      azureBlobSource: {
        containerUrl: containerUrl1,
      }
    },
    "formY": {
      azureBlobFileListSource: {
        containerUrl: containerUrl2,
        fileList: "path/to/fileList.jsonl"
      }
    },
  },
  {
    // Optionally, a text description may be attached to the classifier
    description: "This is an example classifier!"
  }
);

// Classifier building, like model creation operations, returns a poller that eventually produces a
// DocumentClassifierDetails object
const classifierDetails = await poller.pollUntilDone();

const {
  classifierId, // identical to the classifierId given when creating the classifier
  description, // identical to the description given when creating the classifier (if any)
  createdOn, // the Date (timestamp) that the classifier was created
  docTypes // information about the document types in the classifier and their details
} = classifierDetails;
beginBuildDocumentModel(string, DocumentModelSource, DocumentModelBuildMode, BeginBuildDocumentModelOptions)

内容源描述了服务用于读取输入训练数据的机制。 有关详细信息， <xref:DocumentModelContentSource> 请参阅 类型。

示例

const modelId = "aNewModel";

const poller = await client.beginBuildDocumentModel(modelId, { containerUrl: "<SAS-encoded blob container URL>" }, {
  // Optionally, a text description may be attached to the model
  description: "This is an example model!"
});

// Model building, like all other model creation operations, returns a poller that eventually produces a ModelDetails
// object
const modelDetails = await poller.pollUntilDone();

const {
  modelId, // identical to the modelId given when creating the model
  description, // identical to the description given when creating the model
  createdOn, // the Date (timestamp) that the model was created
  docTypes // information about the document types in the model and their field schemas
} = modelDetails;
beginBuildDocumentModel(string, string, DocumentModelBuildMode, BeginBuildDocumentModelOptions)

从一组输入文档和标记字段生成具有给定 ID 的新模型。

模型 ID 可以包含任何文本，只要它不以“prebuilt-”开头， (因为这些模型指的是所有资源) 通用的预生成表单识别器模型，只要它尚不存在于资源中。

表单识别器服务从 Azure 存储容器读取训练数据集，该数据集作为包含 SAS 令牌的容器的 URL 提供，允许服务后端与容器通信。 至少需要“读取”和“列出”权限。 此外，必须根据特定约定组织给定容器中的数据，该约定记录在 用于生成自定义模型的服务文档中。

示例

const modelId = "aNewModel";
const containerUrl = "<training data container SAS URL>";

const poller = await client.beginBuildDocumentModel(modelId, containerUrl, {
  // Optionally, a text description may be attached to the model
  description: "This is an example model!"
});

// Model building, like all other model creation operations, returns a poller that eventually produces a ModelDetails
// object
const modelDetails = await poller.pollUntilDone();

const subModelIds = [
  "documentType1Model",
  "documentType2Model",
  "documentType3Model"
];

// The resulting composed model can classify and extract data from documents
// conforming to any of the above document types
const poller = await client.beginComposeDocumentModel(modelId, subModelIds, {
  description: "This is a composed model that can handle several document types."
});

// Model composition, like all other model creation operations, returns a poller that eventually produces a
// ModelDetails object
const modelDetails = await poller.pollUntilDone();

const {
  modelId, // identical to the modelId given when creating the model
  description, // identical to the description given when creating the model
  createdOn, // the Date (timestamp) that the model was created
  docTypes // information about the document types of the composed submodels
} = modelDetails;
beginCopyModelTo(string, CopyAuthorization, BeginCopyModelOptions)

将具有给定 ID 的模型复制到由给定复制授权编码的资源和模型 ID 中。

请参阅 CopyAuthorization 和 getCopyAuthorization。

示例

// We need a client for the source model's resource
const sourceEndpoint = "https://<source resource name>.cognitiveservices.azure.com";
const sourceCredential = new AzureKeyCredential("<source api key>");
const sourceClient = new DocumentModelAdministrationClient(sourceEndpoint, sourceCredential);

// We create the copy authorization using a client authenticated with the destination resource. Note that these two
// resources can be the same (you can copy a model to a new ID in the same resource).
const copyAuthorization = await client.getCopyAuthorization("<destination model ID>");

// Finally, use the _source_ client to copy the model and await the copy operation
const poller = await sourceClient.beginCopyModelTo("<source model ID>");

// Model copying, like all other model creation operations, returns a poller that eventually produces a ModelDetails
// object

getDocumentModel(string, GetModelOptions)

(DocumentModelDetails) 按 ID 检索有关模型的信息。

此方法可以检索有关自定义模型和预生成模型的信息。

中断性变更

在以前版本的 表单识别器 REST API 和 SDK 中getModel，该方法可能会返回任何模型，甚至可能返回因错误而无法创建的模型。 在新服务版本中， getDocumentModel 和 listDocumentModels仅生成成功创建的模型 (即“已准备就绪”可供) 使用的模型。 现在，通过“操作”API 检索失败的模型，请参阅 getOperation 和 listOperations。

示例

// The ID of the prebuilt business card model
const modelId = "prebuilt-businessCard";

const {
  modelId, // identical to the modelId given when calling `getDocumentModel`
  description, // a textual description of the model, if provided during model creation
  createdOn, // the Date (timestamp) that the model was created
  // information about the document types in the model and their field schemas
