阿里云 ocr识别 银行卡java

示例代码：

import com.aliyun.ocr.Client;
import com.aliyun.ocr.ClientException;
import com.aliyun.ocr.card.CardInfo;
import com.aliyun.ocr.card.CardType;
import com.aliyun.ocr.card.CardUtils;
import com.aliyun.ocr.card.model.BankCard;
import com.aliyun.ocr.card.model.DebitCard;
import com.aliyun.ocr.card.model.CreditCard;
import com.aliyun.ocr.card.result.RecognizeBankCardResult;
import com.aliyun.ocr.card.result.RecognizeDebitCardResult;
import com.aliyun.ocr.card.result.RecognizeCreditCardResult;

public class BankCardOcrDemo {
    private static final String ACCESS_KEY_ID = "<your_access_key_id>";
    private static final String ACCESS_KEY_SECRET = "<your_access_key_secret>";

    public static void main(String[] args) {
        Client client = new Client(ACCESS_KEY_ID, ACCESS_KEY_SECRET);

        String imageUrl = "<your_bank_card_image_url>";
        RecognizeBankCardResult result = null;
        try {
            result = client.recognizeBankCard(imageUrl, null);
        } catch (ClientException e) {
            e.printStackTrace();
        }

        if (result != null) {
            CardInfo cardInfo = result.getCardInfo();
            if (cardInfo != null) {
                CardType cardType = cardInfo.getCardType();
                switch (cardType) {
                    case DebitCard:
                        DebitCard debitCard = CardUtils.convertToDebitCard(cardInfo);
                        // TODO: 处理储蓄卡信息
                        break;
                    case CreditCard:
                        CreditCard creditCard = CardUtils.convertToCreditCard(cardInfo);
                        // TODO: 处理信用卡信息
                        break;
                    case BankCard:
                        BankCard bankCard = CardUtils.convertToBankCard(cardInfo);
                        // TODO: 处理银行卡信息
                        break;
                    default:
                        break;
                }
            }
        }
    }
}

注意替换 `ACCESS_KEY_ID`、`ACCESS_KEY_SECRET` 和 `imageUrl` 为实际值。
