# Aktionen für Amazon Textract mit AWS SDKs
Die folgenden Codebeispiele zeigen, wie Sie einzelne Amazon Textract Textract-Aktionen mit AWS SDKs ausführen. Jedes Beispiel enthält einen Link zu GitHub, wo Sie Anweisungen zum Einrichten und Ausführen des Codes finden.
Diese Auszüge rufen die Amazon Textract API auf und sind Codeauszüge aus größeren Programmen, die im Kontext ausgeführt werden müssen. Sie können Aktionen im Kontext unter [Szenarien für die Verwendung von Amazon Textract AWS SDKs](textract_code_examples_scenarios.md) anzeigen.
Die folgenden Beispiele enthalten nur die am häufigsten verwendeten Aktionen. Eine vollständige Liste finden Sie in der [API-Referenz für Amazon Textract](https://docs.aws.amazon.com/textract/latest/dg/API_Reference.html).

# Verwendung `AnalyzeDocument` mit einem AWS SDK oder CLI
Die folgenden Code-Beispiele zeigen, wie `AnalyzeDocument` verwendet wird.

#### [ CLI ]
**AWS CLI**
**So analysieren Sie Text in einem Dokument**
Das folgende Beispiel für `analyze-document` zeigt, wie Text in einem Dokument analysiert wird.
Linux/macOS:
```
aws textract analyze-document \
--document '{"S3Object":{"Bucket":"bucket","Name":"document"}}' \
--feature-types '["TABLES","FORMS"]'
```
Windows:
```
aws textract analyze-document \
--document "{\"S3Object\":{\"Bucket\":\"bucket\",\"Name\":\"document\"}}" \
--feature-types "[\"TABLES\",\"FORMS\"]" \
--region region-name
```
Ausgabe:
