# `CreateDocumentClassifier` 搭配 AWS SDK 或 CLI 使用
下列程式碼範例示範如何使用 `CreateDocumentClassifier`。
動作範例是大型程式的程式碼摘錄，必須在內容中執行。您可以在下列程式碼範例的內容中看到此動作：
+ [訓練自訂分類器並分類文件](comprehend_example_comprehend_Usage_ComprehendClassifier_section.md)
------
#### [ CLI ]
**AWS CLI**
**建立文件分類器以將文件分類**
下列 `create-document-classifier` 範例開始進行文件分類器模型的訓練程序。訓練資料檔案 `training.csv` 位於 `--input-data-config` 標籤。`training.csv` 是兩欄文件，第一欄提供標籤或分類，第二欄提供文件。
```
aws comprehend create-document-classifier \
--document-classifier-name example-classifier \
--data-access-arn arn:aws:comprehend:us-west-2:111122223333:pii-entities-detection-job/123456abcdeb0e11022f22a11EXAMPLE \
--input-data-config "S3Uri=s3://amzn-s3-demo-bucket/" \
--language-code en
```
輸出：
```
{
"DocumentClassifierArn": "arn:aws:comprehend:us-west-2:111122223333:document-classifier/example-classifier"
}
```
