2、Controller层接口
@Autowiredprivate IMailService mailService;@Value("${qichacha.key}")private String key;@Value("${qichacha.secret}")private String secret;/*** 营业执照识别真伪*/@GetMapping("business_license")public BusinessLicInfo businessLicense(){//获取本地的绝对路径图片File file = new File("D:\\3.png");//进行BASE64位编码String imageBase = BASE64.encodeImgageToBase64(file);imageBase = imageBase.replaceAll("\r\n", "");imageBase = imageBase.replaceAll("\\+", "%2B");//百度云的文字识别接口,后面参数为获取到的tokenString httpUrl = "/rest/2.0/ocr/v1/business_license?access_token="+BaiDuOCR.getAuth();//id_card_side=front 识别正面 id_card_side=back 识别背面String httpArg = "detect_direction=true&id_card_side=front&image=" + imageBase;String jsonResult = BaiDuOCR.request(httpUrl, httpArg);System.out.println("返回的结果--------->" + jsonResult);HashMap<String, String> map = BaiDuOCR.getBusniessLicHashMap(jsonResult);BusinessLicInfo businessLicInfo = new BusinessLicInfo();businessLicInfo.setAddress(map.get("地址"));businessLicInfo.setCeo(map.get("法人"));businessLicInfo.setCode(map.get("证件编号"));businessLicInfo.setCompanyName(map.get("单位名称"));businessLicInfo.setCreditId(map.get("社会信用代码"));businessLicInfo.setDate(map.get("有效期"));businessLicInfo.setType(map.get("类型"));//判断营业执照的真伪String url = "/ECIMatch/CompanyVerify?key=" + key + "&dtype=json" + "®No=" + businessLicInfo.getCreditId()+ "&companyName=" + businessLicInfo.getCompanyName() + "&frname=" + businessLicInfo.getCeo();int timestamp = DateUtil.getSecondTimestamp(new Date());try {String result = HttpClientUtil.doGet(url, MD5Util.MD5(key+timestamp+secret),timestamp+"");System.out.println(result);} catch (Exception e) {e.printStackTrace();}return businessLicInfo;}
3、相关工具类
3.1 DateUtils
import java.util.Date;public class DateUtil {public static int getSecondTimestamp(Date date){if (null == date) {return 0;}String timestamp = String.valueOf(date.getTime());int length = timestamp.length();if (length > 3) {return Integer.valueOf(timestamp.substring(0,length-3));} else {return 0;}}}
3.2 Http请求工具类

至于百度OCR的调用可以参考我的上一边博文基于SpringBoot调用百度ocr实现图片的文字识别功能
