创建和管理处理器

您必须先创建自己的处理器实例，然后才能发送文档进行处理。本页面详细介绍了如何创建和管理处理器。

可用的处理器

如需使用 API 创建处理器实例，您需要知道每种处理器类型的名称。动态获取此列表（使用以下代码），因为您的访问权限可能会发生变化。

公开提供的处理器类型包括：

数字化处理器

OCR_PROCESSOR
FORM_PARSER_PROCESSOR
LAYOUT_PARSER_PROCESSOR

预训练处理器

BANK_STATEMENT_PROCESSOR
EXPENSE_PROCESSOR
FORM_W2_PROCESSOR
ID_PROOFING_PROCESSOR
INVOICE_PROCESSOR
PAYSTUB_PROCESSOR
US_DRIVER_LICENSE_PROCESSOR
US_PASSPORT_PROCESSOR
UTILITY_PROCESSOR

提取 / 分类 / 拆分处理器

CUSTOM_EXTRACTION_PROCESSOR
CUSTOM_CLASSIFICATION_PROCESSOR
CUSTOM_SPLITTING_PROCESSOR
SUMMARIZER_PROCESSOR

列出处理器类型

网页界面

在 Google Cloud 控制台的 Document AI 部分，前往处理器库页面。

前往处理器库
查看或搜索处理器类型列表。

注意：某些处理器的访问权限受限。如果处理器的访问权限受限，您必须申请访问权限并获得批准，才能创建处理器。

REST

此示例展示了如何使用 fetchProcessorTypes 方法列出项目的可用处理器类型。

在使用任何请求数据之前，请先进行以下替换：

LOCATION：处理器的位置，例如：
- us - 美国
- eu - 欧盟
PROJECT_ID：您的 Google Cloud 项目 ID。

HTTP 方法和网址：

GET https://LOCATION-documentai.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION:fetchProcessorTypes

如需发送请求，请选择以下方式之一：

curl

注意：以下命令假定您已使用您的用户账号通过运行 gcloud init 或 gcloud auth login 登录 gcloud CLI，或者使用了 Cloud Shell，这会使您自动登录 gcloud CLI。您可以运行 gcloud auth list 来检查当前活跃的账号。

执行以下命令：

curl -X GET \
     -H "Authorization: Bearer $(gcloud auth print-access-token)" \
     "https://LOCATION-documentai.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION:fetchProcessorTypes"

PowerShell

注意：以下命令假定您已使用您的用户账号通过运行 gcloud init 或 gcloud auth login 登录 gcloud CLI。您可以运行 gcloud auth list 来检查当前活跃的账号。

执行以下命令：

$cred = gcloud auth print-access-token
$headers = @{ "Authorization" = "Bearer $cred" }

Invoke-WebRequest `
    -Method GET `
    -Headers $headers `
    -Uri "https://LOCATION-documentai.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION:fetchProcessorTypes" | Select-Object -Expand Content

响应是一个 ProcessorType 列表，其中显示了可用的处理器类型，以及类别和可用位置。

创建处理器

网页界面

在 Google Cloud 控制台的 Document AI 部分，前往处理器库页面。

前往处理器库
查看或搜索处理器库，找到要创建的处理器。
在列表中点击要创建的处理器类型。

注意：某些处理器的访问权限受限。如果处理器的访问权限受到限制，您必须申请访问权限并获得批准，才能创建该处理器。
在侧边创建处理器窗口中，指定处理器名称。
从列表中选择您的地区。
点击创建以创建处理器。

系统会将您转到处理器的概览标签页，其中包含名称、ID、类型和预测端点等信息。使用此端点发送请求。

REST

此示例展示了如何使用 processors.create 方法创建新的 processor。

在使用任何请求数据之前，请先进行以下替换：

LOCATION：处理器的位置，例如：
- us - 美国
- eu - 欧盟
PROJECT_ID：您的 Google Cloud 项目 ID。
PROCESSOR_TYPE：处理器的类型，例如：
- OCR_PROCESSOR
- FORM_PARSER_PROCESSOR
- INVOICE_PROCESSOR
- US_DRIVER_LICENSE_PROCESSOR
DISPLAY_NAME：处理器的显示名称。

HTTP 方法和网址：

POST https://LOCATION-documentai.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/processors

请求 JSON 正文：

{
  "type": "PROCESSOR_TYPE",
  "displayName": "DISPLAY_NAME"
}

如需发送请求，请选择以下方式之一：

curl

将请求正文保存在名为 request.json 的文件中，然后执行以下命令：

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

查看处理器的详细信息

网页界面

在 Google Cloud 控制台的 Document AI 部分，前往处理器页面。

前往“处理器”页面
在处理器列表中，点击要查看其详细信息的处理器的名称。

系统会将您转到处理器的概览标签页，其中包含名称、ID、类型和预测端点等信息。

REST

此示例展示了如何使用 processors.get 方法获取有关现有 Processor 的详细信息。

在使用任何请求数据之前，请先进行以下替换：

LOCATION：处理器的位置，例如：
- us - 美国
- eu - 欧盟
PROJECT_ID：您的 Google Cloud 项目 ID。
PROCESSOR_ID：自定义处理器的 ID。

HTTP 方法和网址：

GET https://LOCATION-documentai.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/processors/PROCESSOR_ID

如需发送请求，请选择以下方式之一：

curl

执行以下命令：

curl -X GET \
     -H "Authorization: Bearer $(gcloud auth print-access-token)" \
     "https://LOCATION-documentai.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/processors/PROCESSOR_ID"

PowerShell

注意：以下命令假定您已使用您的用户账号通过运行 gcloud init 或 gcloud auth login 登录 gcloud CLI。您可以运行 gcloud auth list 来检查当前活跃的账号。

执行以下命令：

$cred = gcloud auth print-access-token
$headers = @{ "Authorization" = "Bearer $cred" }

Invoke-WebRequest `
    -Method GET `
    -Headers $headers `
    -Uri "https://LOCATION-documentai.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/processors/PROCESSOR_ID" | Select-Object -Expand Content

停用处理器

网页界面

在 Google Cloud 控制台的 Document AI 部分，前往处理器页面。

前往“处理器”页面
1. 在操作菜单 中，点击处理器旁边的停用处理器。

REST

此示例展示了如何使用 processors.disable 方法停用现有的 Processor。

在使用任何请求数据之前，请先进行以下替换：

LOCATION：处理器的位置，例如：
- us - 美国
- eu - 欧盟
PROJECT_ID：您的 Google Cloud 项目 ID。
PROCESSOR_ID：自定义处理器的 ID。

HTTP 方法和网址：

POST https://LOCATION-documentai.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/processors/PROCESSOR_ID:disable

如需发送请求，请选择以下方式之一：

curl

执行以下命令：

curl -X POST \
     -H "Authorization: Bearer $(gcloud auth print-access-token)" \
     -H "Content-Type: application/json; charset=utf-8" \
     -d "" \
     "https://LOCATION-documentai.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/processors/PROCESSOR_ID:disable"

PowerShell

注意：以下命令假定您已使用您的用户账号通过运行 gcloud init 或 gcloud auth login 登录 gcloud CLI。您可以运行 gcloud auth list 来检查当前活跃的账号。

执行以下命令：

$cred = gcloud auth print-access-token
$headers = @{ "Authorization" = "Bearer $cred" }

Invoke-WebRequest `
    -Method POST `
    -Headers $headers `
    -Uri "https://LOCATION-documentai.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/processors/PROCESSOR_ID:disable" | Select-Object -Expand Content

该响应是一个长时间运行的操作

  }
}

如需轮询长时间运行的操作，请调用 operations.get：
