 *  第四 总结

# 第一、背景 #

银行卡，身份证，驾驶证等证件扫描和识别有很广泛的应用场景，比如用户实名认证时。

# 第二、接入 #

这里使用百度的文字识别功能。登陆百度的[AI开放平台][AI]找到[文字识别][Link 1]文档。创建一个应用[地址][Link 2]  
创建好的应用会有三个关键参数。AppID，API Key，Secret Key个会程序里会有使用。

使用SDK  
maven引入方式：

<dependency>
        <groupId>com.baidu.aip</groupId>
        <artifactId>java-sdk</artifactId>
        <version>${baidu-version}</version>
    </dependency>

参数配置类AlibabaMainConfig.java:

package yui.bss.baidu.config;
    
    public class AlibabaMainConfig { 
        public static final String APP_ID = "144444951468";
        public static final String API_KEY = "ahvukw8hqlhoAqqbXrXXXXqPoCyE";
        public static final String SECRET_KEY = "RqwNLpnH8YwctkkRI07lpv8kpXXXXXXXUFfR";
    }

AipOcr是Optical Character Recognition的Java客户端，为使用Optical Character Recognition的开发人员提供了一系列的交互方法。用户可以参考如下代码新建一个AipOcr,初始化完成后建议单例使用,避免重复获取access\_token。  
配置AipOcr  
如果用户需要配置AipOcr的一些细节参数，可以在构造AipOcr之后调用接口设置参数，目前只支持以下参数：

setConnectionTimeoutInMillis：建立连接的超时时间（单位：毫秒）  
setSocketTimeoutInMillis： 通过打开的连接传输数据的超时时间（单位：毫秒）  
setHttpProxy ：设置http代理服务器  
setSocketProxy ：设置socket代理服务器 （http和socket类型代理服务器只能二选一）

AlipayClientFactory.java:

package yui.bss.baidu.config;
    
    import javax.annotation.PostConstruct;
    
    import org.apache.log4j.Logger;
    import org.springframework.stereotype.Service;
    
    import com.baidu.aip.ocr.AipOcr;
    
    @Service
    public class AlipayClientFactory {
        private static Logger logger = Logger.getLogger(AlipayClientFactory.class);
        public static AipOcr client;
    
        @PostConstruct
        public void postConstruct() throws Exception {
            logger.info("百度环境初始化开始");
            // 初始化一个AipOcr
            AlipayClientFactory.client = new AipOcr(AlibabaMainConfig.APP_ID, AlibabaMainConfig.API_KEY, AlibabaMainConfig.SECRET_KEY);
            // 可选：设置网络连接参数
            client.setConnectionTimeoutInMillis(2000);
            client.setSocketTimeoutInMillis(60000);
            logger.info("百度环境初始化结束");
        }
    }

创建一个接口，用于外部调用IBaiduImgMgrx.java

package yui.bss.baidu.service;
    
    import yui.bss.baidu.bean.BankCardBean;
    import yui.bss.baidu.bean.DrivingLicenseBean;
    import yui.bss.baidu.bean.IdCardBean;
    import yui.bss.baidu.bean.PlateLicense;
    
    public interface IBaiduImgMgrx { 
    
        /** * 通过图片地址url识别身份证信息 * * @param imgUrl */
        IdCardBean doBaiduIdCard(String imgUrl);
    
        /** * 银行卡识别 * * @param imgUrl */
        BankCardBean doBankCard(String imgUrl);
    
        /** * 车牌识别 * * @param imgUrl */
        PlateLicense doPlateLicense(String imgUrl);
    
        /** *驾驶证识别 * * @param imgUrl */
        DrivingLicenseBean doDrivingLicense(String imgUrl);
    
    }

接口实现如下BaiduImgMgrxImpl.java:

package yui.bss.baidu.service;
    
    import java.util.HashMap;
    
    import org.apache.log4j.Logger;
    import org.json.JSONObject;
    import org.springframework.stereotype.Service;
    
    import com.alibaba.fastjson.JSON;
    
    import yui.bss.baidu.bean.BankCardBean;
    import yui.bss.baidu.bean.DrivingLicenseBean;
    import yui.bss.baidu.bean.IdCardBean;
    import yui.bss.baidu.bean.PlateLicense;
    import yui.bss.baidu.config.AlipayClientFactory;
    import yui.comn.util.FileUtil;
    
    @Service
    public class BaiduImgMgrxImpl implements IBaiduImgMgrx {
        private static Logger logger = Logger.getLogger(BaiduImgMgrxImpl.class);
    
        @Override
        public IdCardBean doBaiduIdCard(String imgUrl) {
            // 重写接口方法：2018年3月19日
            // 传入可选参数调用接口
            HashMap<String, String> options = new HashMap<String, String>();
            options.put("detect_direction", "true");
            options.put("detect_risk", "false");
    
            // 通用文字识别, 图片参数为远程url图片
            byte[] file = FileUtil.readNetImage(imgUrl);
            JSONObject res = AlipayClientFactory.client.idcard(file, "front", options);
            IdCardBean idCardFront = JSON.parseObject(res.toString(), IdCardBean.class);
            return idCardFront;
        }
    
        @Override
        public BankCardBean doBankCard(String imgUrl) {
            // 传入可选参数调用接口
            HashMap<String, String> options = new HashMap<String, String>();
            options.put("detect_direction", "true");
            options.put("detect_risk", "false");
    
            // 通用文字识别, 图片参数为远程url图片
            byte[] file = FileUtil.readNetImage(imgUrl);
            JSONObject res = AlipayClientFactory.client.bankcard(file, options);
            BankCardBean bankCardBean = JSON.parseObject(res.toString(), BankCardBean.class);
            return bankCardBean;
        }
    
        @Override
        public PlateLicense doPlateLicense(String imgUrl) {
            // 传入可选参数调用接口
            HashMap<String, String> options = new HashMap<String, String>();
            options.put("multi_detect", "true");
    
            // 通用文字识别, 图片参数为远程url图片
            byte[] file = FileUtil.readNetImage(imgUrl);
            JSONObject res = AlipayClientFactory.client.plateLicense(file, options);
            PlateLicense plateLicense = JSON.parseObject(res.toString(), PlateLicense.class);
            return plateLicense;
        }
    
        @Override
        public DrivingLicenseBean doDrivingLicense(String imgUrl) {
            // 传入可选参数调用接口
            HashMap<String, String> options = new HashMap<String, String>();
            options.put("detect_direction", "true");
    
            // 通用文字识别, 图片参数为远程url图片
            byte[] file = FileUtil.readNetImage(imgUrl);
            JSONObject res = AlipayClientFactory.client.drivingLicense(file, options);
            DrivingLicenseBean drivingLicenseBean = JSON.parseObject(res.toString(), DrivingLicenseBean.class);
            return drivingLicenseBean;
        }
    }

4.驾驶证识别结果类PlateLicense.java:

package yui.bss.baidu.bean;
    
    import java.util.List;
    
    /** * @author chenyuan * @version 创建时间：2018年3月19日 下午5:20:20 * @ClassName 类名称 * @Description 类描述 */
    public class PlateLicense { 
        private long log_id;
        private List<Words_result> words_result;
    
        public void setLog_id(long log_id) {

                return number;
            }
    
        }
    }

到此,银行卡，身份证，驾驶证识别信息已经做完.

# 第三、 测试 #

测试使用springMVC框架写个接口如下:

/** * 身份证图片扫描 * * @return * @throws Exception */
        @RequestMapping(value = "/baiduIdcard", method = RequestMethod.POST)
        @ResponseBody
        public Object baiduIdcard(@RequestParam(value = "imgUrl", required = true) String imgUrl){
            try {
                IdCardBean idCardFront = baiduImgMgrx.doBaiduIdCard(imgUrl);
                return buildObj(idCardFront);
            } catch (Exception e) {
                logger.info("error.", e);
                return buildFailure("百度身份证验证失败");
            }
        }
    
        /** * 银行卡扫描 * * @return * @throws Exception */
        @RequestMapping(value = "/bankCard", method = RequestMethod.POST)
        @ResponseBody
        public Object bankCard(@RequestParam(value = "imgUrl", required = true) String imgUrl){
            try {
                BankCardBean bankCardBean = baiduImgMgrx.doBankCard(imgUrl);
                return buildObj(bankCardBean);
            } catch (Exception e) {
                logger.info("error.", e);
                return buildFailure("银行卡扫描失败");
            }
        }
    
        /** * 驾驶证识别 * * @return * @throws Exception */
        @RequestMapping(value = "/drivingLicense", method = RequestMethod.POST)
        @ResponseBody
        public Object drivingLicense(@RequestParam(value = "imgUrl", required = true) String imgUrl){
            try {
                DrivingLicenseBean drivingLicenseBean = baiduImgMgrx.doDrivingLicense(imgUrl);
                return buildObj(drivingLicenseBean);
            } catch (Exception e) {
                logger.info("error.", e);
                return buildFailure("车牌识别失败");
            }
        }
    
        /** * 车牌识别 * * @return * @throws Exception */
        @RequestMapping(value = "/plateLicense", method = RequestMethod.POST)
        @ResponseBody
        public Object plateLicense(@RequestParam(value = "imgUrl", required = true) String imgUrl){
            try {
                PlateLicense plateLicense = baiduImgMgrx.doPlateLicense(imgUrl);
                return buildObj(plateLicense);
            } catch (Exception e) {
                logger.info("error.", e);
                return buildFailure("车牌识别失败");
            }
        }
