ocr识别证件照；主要是使用阿里云j接口：
1、注册阿里云账户获取appKey \appSer
2、调用接口
2.1：定义常量
public class OrcHttpConstant { /** * 驾驶证识别appCode */ public static final String OCR_APPCODE = "033f4b0f719d4e01b431a18cba7a79e1"; /** * 调用方式 */ public static final String MONTH = "POST"; /** * 驾驶证识别url */ public static final String DRIVER_LICENSE_HOST = "https://cardriving.market.alicloudapi.com"; /** * 驾驶证识别path */ public static final String DRIVER_LICENSE_PATH = "/rest/160601/ocr/ocr_driver_license.json"; /** * 身份证识别url */ public static final String ID_CARD_HOST = "https://cardnumber.market.alicloudapi.com"; /** * 身份证识别path */ public static final String ID_CARD_PATH = "/rest/160601/ocr/ocr_idcard.json"; /** * 行驶证识别url */ public static final String VEHICLE_LICENSE_HOST = "https://driving.market.alicloudapi.com"; /** * 行驶证识别path */ public static final String VEHICLE_LICENSE_PATH = "/rest/160601/ocr/ocr_vehicle.json"; /** * 营业执照证识别url */ public static final String BUSINESS_LICENSE_HOST = "https://bizlicense.market.alicloudapi.com"; /** * 营业执照证识别path */ public static final String BUSINESS_LICENSE_PATH = "/rest/160601/ocr/ocr_business_license.json"; /** * 发票识别url */ public static final String INVOICE_LICENSE_HOST = "https://dgfp.market.alicloudapi.com"; /** * 发票识别path */ public static final String INVOICE_LICENSE_PATH = "/ocrservice/invoice"; }
