내 Android 용 애플리케이션에 Amazon Dynamo DB를 구현하려고합니다. id (string), status (number)와 같은 속성으로 생성 된 테이블. AmazonClientException이 "오류 응답을 언 마샬 할 수 없습니다"라는 메시지가 나타납니다. 누구든지 나를 제안한다. 여기 Android Amazon DynamoDB 400 잘못된 요청 오류
내 코드는
..try {
AmazonDynamoDBClient ddb = DynamoDB.getInstance();
Map<String, AttributeValue> item = new HashMap<String, AttributeValue>();
item.put("googleid", new AttributeValue().withS("Test"));
item.put("status", new AttributeValue().withN("1234"));
PutItemRequest putItemRequest = new PutItemRequest("android_news_push", item);
PutItemResult putItemResult = ddb.putItem(putItemRequest);
} catch (AmazonServiceException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (AmazonClientException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
내 예외이다 : 당신이 당신의 AWS 자격 증명에 문제가있는 것처럼
