開始使用文件智慧服務
重要
- Azure 認知服務表格辨識器現在稱為 Azure AI 文件智慧服務。
- 某些平台仍在等候重新命名更新。
- 我們文件中的 Azure 表格辨識器或文件智慧服務全都是指相同的 Azure 服務。
Azure AI 文件智慧服務/表格辨識器是雲端式 Azure AI 服務，其使用機器學習從文件中擷取機碼值組、文字、資料表和重要資料。
您可以使用程式設計語言 SDK 或呼叫 REST API，輕鬆地將檔案處理模型整合到工作流程和應用程式中。
針對此快速入門，建議您在學習技術時使用免費服務。 請記住，免費的頁數限制為每個月 500 頁。
若要深入了解 API 的功能和開發選項，請瀏覽我們的概觀 (部分機器翻譯) 頁面。

必要條件
Azure 訂用帳戶 - 建立免費帳戶。
目前的 Visual Studio 整合式開發環境 (IDE) 版本。
Azure AI 服務或文件智慧服務資源。 擁有 Azure 訂用帳戶後，請在 Azure 入口網站中建立單一服務或 Azure AI 多重服務資源，以取得金鑰與端點。
您可以使用免費定價層 (
F0) 來試用服務，之後可升級至付費層以用於實際執行環境。
提示
如果您打算在單一端點/金鑰下存取多個 Azure AI 服務，請建立 Azure AI 服務資源。 若為僅限文件智慧服務存取，請建立文件智慧服務資源。 請注意，如果您想要使用 Microsoft Entra 驗證 (部分機器翻譯)，需要使用單一服務資源。
部署資源之後，請選取 [移至資源]。 您需要使用已建立資源的金鑰和端點，將應用程式連線至文件智慧服務 API。 您稍後會在快速入門中將金鑰和端點貼上至程式碼中：

重要
完成時，請記得從程式碼中移除金鑰，且不要公開張貼金鑰。 在生產環境中，請使用安全的方式來儲存和存取您的認證，例如 Azure Key Vault。 如需詳細資訊，請參閱 Azure AI 服務安全性。
版面配置模型
從文件擷取文字、選取標記、文字樣式、表格結構和週框區域座標。
- 在此範例中，您需要來自 URI 的文件檔案。 您可以針對本快速入門使用我們的範例文件 (英文)。
- 我們已將檔案 URI 值新增至指令碼頂端的
Uri fileUri變數。 - 若要從 URI 上的指定檔案擷取配置，請使用
StartAnalyzeDocumentFromUri方法並傳遞prebuilt-layout作為模型識別碼。 傳回值是AnalyzeResult物件，包含來自提交文件的資料。

完成時，請記得從程式碼中移除金鑰，且不要公開張貼金鑰。 在生產環境中，請使用安全的方式來儲存和存取您的認證，例如 Azure Key Vault。 如需詳細資訊，請參閱 Azure AI 服務安全性。
版面配置模型
從文件擷取文字、選取標記、文字樣式、表格結構和週框區域座標。
- 在此範例中，您需要位於某個 URI 的文件檔案。 您可以針對本快速入門使用我們的範例文件 (英文)。
- 若要在 URI 上分析指定檔案，您將使用
beginAnalyzeDocumentFromUrl方法並傳遞prebuilt-layout作為模型識別碼。傳回值是AnalyzeResult物件，其中包含提交文件的相關資料。 - 我們已將檔案 URI 值新增至主要方法中的
documentUrl變數。

最新的 Visual Studio Code 版本或您慣用的 IDE。 如需詳細資訊，請參閱 Visual Studio Code 中的 Node.js。
最新
LTS版的 Node.js (英文)。Azure AI 服務或文件智慧服務資源。 擁有 Azure 訂閱後，請在 Azure 入口網站中建立單一服務或多重服務文件智慧服務資源，以取得您的金鑰和端點。 您可以使用免費定價層 (
F0) 來試用服務，之後可升級至付費層以用於實際執行環境。提示
如果您打算在單一端點/金鑰下存取多個 Azure AI 服務，請建立 Azure AI 服務資源。 若為僅限文件智慧服務存取，請建立文件智慧服務資源。 請注意，如果您想要使用 Microsoft Entra 驗證 (部分機器翻譯)，需要使用單一服務資源。
部署資源之後，請選取 [移至資源]。 您需要使用已建立資源的金鑰和端點，將應用程式連線至文件智慧服務 API。 您稍後會在快速入門中將金鑰和端點貼上至程式碼中：
設定
建立新 Node.js 快速應用程式：在主控台視窗 (例如 cmd、PowerShell 或 Bash) 中，為您的應用程式建立名為
doc-intel-app的新目錄，並瀏覽至該目錄。mkdir doc-intel-app && cd doc-intel-app執行
npm init命令來初始化應用程式，並建構您的專案。npm init使用終端機中顯示的提示來指定專案的屬性。
- 名稱、版本號碼和進入點是最重要的屬性。
- 建議為進入點名稱保留
index.js。 描述、測試命令、GitHub 存放庫、關鍵字、作者和授權資訊皆為選擇性屬性，在此專案中可以跳過。 - 選取 [退回] 或 [輸入]，以接受括弧中的建議。
- 完成提示後，將會在 doc-intel-app 目錄中建立

在本快速入門中，請使用下列功能，從表單和文件中分析及擷取資料：
必要條件
Azure 訂用帳戶 - 建立免費帳戶。
Python 3.7 或更新版本 (英文)。
- 您安裝的 Python 應包含 pip。 您可以在命令列上執行
pip --version來檢查是否已安裝 pip。 安裝最新版本的 Python 以取得 pip。
- 您安裝的 Python 應包含 pip。 您可以在命令列上執行
最新的 Visual Studio Code 版本或您慣用的 IDE。 如需詳細資訊，請參閱 Visual Studio Code 中的 Python 使用者入門。
Azure AI 服務或文件智慧服務資源。 擁有 Azure 訂閱後，請在 Azure 入口網站中建立單一服務或多重服務文件智慧服務資源，以取得您的金鑰和端點。 您可以使用免費定價層 (
F0) 來試用服務，之後可升級至付費層以用於實際執行環境。
提示
如果您打算在單一端點/金鑰下存取多個 Azure AI 服務，請建立 Azure AI 服務資源。 若為僅限文件智慧服務存取，請建立文件智慧服務資源。 請注意，如果您想要使用 Microsoft Entra 驗證 (部分機器翻譯)，需要使用單一服務資源。
部署資源之後，請選取 [移至資源]。 您需要使用已建立資源的金鑰和端點，將應用程式連線至文件智慧服務 API。 您稍後會在快速入門中將金鑰和端點貼上至程式碼中：
設定
在本機環境中開啟終端機視窗，並使用 pip 安裝適用於 Python 的 Azure AI 文件智慧服務用戶端程式庫：
pip install azure-ai-documentintelligence==1.0.0b4
pip install azure-ai-formrecognizer==3.3.0
pip install azure-ai-formrecognizer==3.2.0b6
建立 Python 應用程式
若要與此文件智慧服務互動，您必須建立 DocumentIntelligenceClient 類別的執行個體。 若要這樣做，請使用 key 從 Azure 入口網站建立 AzureKeyCredential，並使用 AzureKeyCredential 和文件智慧服務 endpoint 來建立 DocumentIntelligenceClient 執行個體。
若要與此文件智慧服務互動，您必須建立 DocumentAnalysisClient 類別的執行個體。 若要這樣做，請使用 key 從 Azure 入口網站建立 AzureKeyCredential，並使用 AzureKeyCredential 和文件智慧服務 endpoint 來建立 DocumentAnalysisClient 執行個體。
重要
完成時，請記得從程式碼中移除金鑰，且不要公開張貼金鑰。 在生產環境中，請使用安全的方式來儲存和存取您的認證，例如 Azure Key Vault。 如需詳細資訊，請參閱 Azure AI 服務安全性。
版面配置模型
從文件擷取文字、選取標記、文字樣式、表格結構和週框區域座標。
- 在此範例中，您需要來自 URL 的文件檔案。 您可以針對本快速入門使用我們的範例文件 (英文)。
- 我們已將檔案 URI 值新增至

在本快速入門中，您使用文件智慧服務模型分析了多種表單和文件。 接下來，請探索文件智慧服務工作室和參考文件以深入了解文件智慧服務 API。
下一步
- 在 GitHub 上尋找更多範例 (英文)。
- 在 GitHub 上尋找更多範例 (英文)。
此內容適用於： 
v2.1 | 最新版本： 
v4.0 (預覽版)
使用您選擇的程式設計語言或 REST API 開始使用 Azure AI 文件智慧服務。 文件智慧服務是雲端式 Azure AI 服務，其使用機器學習從文件中擷取機碼值組、文字和資料表。 當您學習技術時，我們建議您使用免費的服務。 請記住，免費的頁數限制為每個月 500 頁。
若要深入了解文件智慧服務的功能和開發選項，請瀏覽我們的概觀 (部分機器翻譯) 頁面。
參考文件 | 程式庫來源程式碼 | 套件 (NuGet) | 範例
在本快速入門中，您會使用下列 API 從表單和文件中擷取結構化資料：
必要條件
Azure 訂用帳戶 - 建立免費帳戶。
目前的 Visual Studio 整合式開發環境 (IDE) 版本。
Azure AI 服務或文件智慧服務資源。 擁有 Azure 訂用帳戶後，請在 Azure 入口網站中建立單一服務或多重服務文件智慧服務資源，以取得您的金鑰與端點。 您可以使用免費定價層 (
F0) 來試用服務，之後可升級至付費層以用於實際執行環境。提示
如果您打算在單一端點/金鑰下存取多個 Azure AI 服務，請建立 Azure AI 服務資源。 若為僅限文件智慧服務存取，請建立文件智慧服務資源。 請注意，如果您想要使用 Microsoft Entra 驗證 (部分機器翻譯)，需要使用單一服務資源。
部署資源之後，請選取 [移至資源]。 您需要使用已建立資源的金鑰和端點，將應用程式連線至文件智慧服務 API。 您稍後會在快速入門中將金鑰和端點貼上至程式碼中：
設定
啟動 Visual Studio 2019。
在開始頁面中，選擇 [建立新的專案]。
在 [建立新的專案] 頁面的搜尋方塊中，輸入主控台。 選擇 [主控台應用程式] 範本，然後選擇 [下一步]。
在 [設定新專案] 對話方塊視窗中，於 [專案名稱] 方塊中輸入
formRecognizer_quickstart。 接著，選擇 [下一步]。![Visual Studio [設定新專案] 對話視窗的螢幕擷取畫面。](../media/quickstarts/configure-new-project.png?view=doc-intel-4.0.0)
在 [其他資訊] 對話方塊視窗中，選取 [.NET 5.0 (目前)]，然後選取 [建立]。
使用 NuGet 安裝用戶端程式庫
於您的 formRecognizer_quickstart 專案上按一下滑鼠右鍵，然後選取 [管理 NuGet 套件]。
選取 [瀏覽] 索引標籤，然後輸入 [Azure.AI.FormRecognizer]。
從下拉式功能表中選取 3.1.1 版，然後選取 [安裝]。
建置您的 應用程式
若要與此文件智慧服務互動，您必須建立 FormRecognizerClient 類別的執行個體。 若要這樣做，您可以使用金鑰建立 AzureKeyCredential，並使用 AzureKeyCredential 和您的文件智慧服務 endpoint 建立 FormRecognizerClient 執行個體。
注意
- 從 .NET 6 開始，使用
console範本的新專案會產生與舊版不同的新程式樣式。 - 新輸出會使用最新的 C# 功能，以簡化您需要撰寫的程式碼。
- 當您使用較新版本時，只需要撰寫
Main方法的本文。 您不需要包含最上層陳述式、全域 Using 指示詞或隱含 Using 指示詞。 - 如需詳細資訊，請參閱新的 C# 範本產生最上層陳述式。
開啟 Program.cs 檔案。
包含下列 Using 指示詞：
using Azure;
using Azure.AI.FormRecognizer;
using Azure.AI.FormRecognizer.Models;
using System.Threading.Tasks;
- 設定您的
endpoint和key環境變數，並建立您的AzureKeyCredential和FormRecognizerClient執行個體：
private static readonly string endpoint = "your-form-recognizer-endpoint";
private static readonly string key = "your-api-key";
private static readonly AzureKeyCredential credential = new AzureKeyCredential(key);
刪除行
Console.Writeline("Hello World!");，並將其中一個試試看程式碼範例新增至 Program.cs 檔案：
請選取程式碼範例以複製並貼上到應用程式的 Main 方法中：
重要
完成時，請記得從程式碼中移除金鑰，且不要公開張貼金鑰。 在生產環境中，請使用安全的方式來儲存和存取您的認證，例如 Azure Key Vault。 如需詳細資訊，請參閱 Azure AI 服務安全性一文。
試試看：配置模型
從文件中擷取文字、選取標記、文字樣式、資料表結構及其週框區域座標。
- 在此範例中，您需要位於某個 URI 的文件檔案。 您可以針對本快速入門使用我們的範例文件 (英文)。
- 我們已將檔案 URI 值新增至
formUri變數。 - 若要從 URI 上的指定檔案擷取配置，請使用
StartRecognizeContentFromUriAsync方法。
將下列程式碼新增至版面配置應用程式 Program.cs 檔案：
FormRecognizerClient recognizerClient = AuthenticateClient();
Task recognizeContent = RecognizeContent(recognizerClient);
Task.WaitAll(recognizeContent);
private static FormRecognizerClient AuthenticateClient()
{
var credential = new AzureKeyCredential(key);
var client = new FormRecognizerClient(new Uri(endpoint), credential);
return client;
}
private static async Task RecognizeContent(FormRecognizerClient recognizerClient)
{
string formUrl = "https://raw.githubusercontent.com/Azure-Samples/cognitive-services-REST-api-samples/master/curl/form-recognizer/sample-layout.pdf";
FormPageCollection formPages = await recognizerClient
.StartRecognizeContentFromUri(new Uri(formUrl))
.WaitForCompletionAsync();
foreach (FormPage page in formPages)
{
Console.WriteLine($"Form Page {page.PageNumber} has {page.Lines.Count} lines.");
for (int i = 0; i < page.Lines.Count; i++)

執行您的應用程式
瀏覽至 form_recognizer_quickstart.py 檔案所在的資料夾。
在您的終端機中輸入下列命令：
python form_recognizer_quickstart.py
| 文件智慧服務 REST API | Azure REST API 參考 |
在本快速入門中，您會使用下列 API 從表單和文件中擷取結構化資料：
必要條件
Azure 訂用帳戶 - 建立免費帳戶
已安裝 cURL。
PowerShell 6.0 版以上，或類似的命令列應用程式。
Azure AI 服務或文件智慧服務資源。 擁有 Azure 訂用帳戶後，請在 Azure 入口網站中建立單一服務或多重服務文件智慧服務資源，以取得您的金鑰與端點。 您可以使用免費定價層 (
F0) 來試用服務，之後可升級至付費層以用於實際執行環境。提示
如果您打算在單一端點/金鑰下存取多個 Azure AI 服務，請建立 Azure AI 服務資源。 若為僅限文件智慧服務存取，請建立文件智慧服務資源。 請注意，如果您想要使用 Microsoft Entra 驗證 (部分機器翻譯)，需要使用單一服務資源。
部署資源之後，請選取 [移至資源]。 您需要使用已建立資源的金鑰和端點，將應用程式連線至文件智慧服務 API。 您稍後會在快速入門中將金鑰和端點貼上至程式碼中：
請選取程式碼範例，以複製並貼到您的應用程式中：
重要
完成時，請記得從程式碼中移除金鑰，且不要公開張貼金鑰。 在生產環境中，請使用安全的方式來儲存和存取您的認證，例如 Azure Key Vault。 如需詳細資訊，請參閱 Azure AI 服務安全性。
試試看：版面配置模型
- 在此範例中，您需要位於某個 URI 的文件檔案。 您可以針對本快速入門使用我們的範例文件 (英文)。
- 將
{endpoint}取代為您使用文件智慧服務訂用帳戶取得的端點。 - 將
{key}取代為您在先前的步驟中複製的金鑰。 - 將
\"{your-document-url}取代為範例文件 URL：
https://raw.githubusercontent.com/Azure-Samples/cognitive-services-REST-api-samples/master/curl/form-recognizer/sample-layout.pdf
要求
curl -v -i POST "https://{endpoint}/formrecognizer/v2.1/layout/analyze" -H "Content-Type: application/json" -H "Ocp-Apim-Subscription-Key: {key}" --data-ascii "{'urlSource': '{your-document-url}'}"
Operation-Location
您收到 202 (Success) 回應，其中包含 Operation-Location 標頭。 此標頭的值會包含一個結果識別碼，可用來查詢非同步作業狀態並取得結果：
https://cognitiveservice/formrecognizer/v2.1/layout/analyzeResults/{resultId}。
在下列範例中，URL 中在 analyzeResults/ 之後的字串就是結果識別碼。
https://cognitiveservice/formrecognizer/v2/layout/analyzeResults/54f0b076-4e38-43e5-81bd-b85b8835fdfb
取得配置結果
呼叫分析配置API 後，您可以呼叫取得分析配置結果 API 來取得作業狀態並擷取資料。 執行命令之前，請進行下列變更：
- 將
{endpoint}取代為您使用文件智慧服務訂用帳戶取得的端點。 - 將
{key}取代為您在先前的步驟中複製的金鑰。 - 將
{resultId}取代為先前步驟中的結果識別碼。
要求
curl -v -X GET "https://{endpoint}/formrecognizer/v2.1/layout/analyzeResults/{resultId}" -H "Ocp-Apim-Subscription-Key: {key}"
檢查結果
