建立及管理處理器

必須先建立處理器執行個體，才能傳送要處理的文件。這個頁面提供了建立及管理處理器的詳細資料。

可用的處理器

如要使用 API 建立處理器執行個體，您必須知道每種處理器類型的名稱。請動態取得這份清單 (使用下列程式碼)，因為您的存取權可能會變更。

公開可用的處理器類型如下：

數位化處理器

  • OCR_PROCESSOR
  • FORM_PARSER_PROCESSOR
  • LAYOUT_PARSER_PROCESSOR

預先訓練的處理器

  • BANK_STATEMENT_PROCESSOR
  • EXPENSE_PROCESSOR
  • FORM_W2_PROCESSOR
  • ID_PROOFING_PROCESSOR
  • INVOICE_PROCESSOR
  • PAYSTUB_PROCESSOR
  • US_DRIVER_LICENSE_PROCESSOR
  • US_PASSPORT_PROCESSOR
  • UTILITY_PROCESSOR

擷取 / 分類 / 分割處理器

  • CUSTOM_EXTRACTION_PROCESSOR
  • CUSTOM_CLASSIFICATION_PROCESSOR
  • CUSTOM_SPLITTING_PROCESSOR
  • SUMMARIZER_PROCESSOR

列出處理器類型

網路使用者介面

  1. 在 Google Cloud 控制台的「Document AI」專區中，前往「Processor Gallery」(處理器庫) 頁面。

    前往處理器庫

  2. 查看或搜尋處理器類型清單。

REST

這個範例說明如何使用 fetchProcessorTypes 方法，列出專案的可用處理器類型。

使用任何要求資料之前，請先修改下列項目的值：

  • LOCATION：處理器的位置，例如：
    • us - 美國
    • eu - 歐盟
  • PROJECT_ID： Google Cloud 專案 ID。

HTTP 方法和網址：

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

如要傳送要求，請選擇以下其中一個選項：

curl

執行下列指令： 

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

PowerShell

執行下列指令： 

$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

回應是 ProcessorType 清單，顯示可用的處理器類型，以及類別和可用位置。
