印刷文字识别-身份证识别(阿里云)
以下是自己根据阿里云api文档说明封装的工具类，主要是获取阿里云Oss身份证图片信息

工具类在tp5.0中的结构位置如下图
正常返回示例
正面返回结果： { "address" : "浙江省杭州市余杭区文一西路969号", #地址信息 "config_str" : "{\\\"side\\\":\\\"face\\\"}", #配置信息，同输入configure "face_rect":{ "angle": -90, "center":{ "x" : 952, "y" : 325.5 }, "size":{ "height":181.99, "width":164.99 } }, #人脸位置，center表示人脸矩形中心坐标，size表示人脸矩形长宽，angle表示矩形顺时针旋转的度数。 "name" : "张三", #姓名 "nationality": "汉"， #民族 "num" : "1234567890", #身份证号 "sex" : "男", #性别 "birth" : "20000101", #出生日期 "nationality" : "汉", #民族 "success" : true #识别结果，true表示成功，false表示失败 } 反面返回结果: { "config_str" : "{\\\"side\\\":\\\"back\\\"}",#配置信息，同输入configure "start_date" : "19700101", #有效期起始时间 "end_date" : "19800101", #有效期结束时间 "issue" : "杭州市公安局", #签发机关 "success" : true #识别结果，true表示成功，false表示失败 }
使用此工具类可参考如下步骤
1.Controller引入工具类 use Helper\AutoRecognition;
2.
public function save(Request $request) { $param = $request->only([‘username‘, ‘idnum‘, ‘mobile‘, ‘idcard_a‘, ‘idcard_b‘]); $param[‘userid‘] = $this->userid; $param[‘status‘] = 0; //身份证正面识别 $res = self::check_idcard_face_message($param); if (!$res) { return Response::response(1,‘填写身份证号码与证件号码不符‘); } //身份证反面识别 $res = self::check_idcard_back_message($param); // dump($res);exit; if (!$res) { return Response::response(1,‘身份证已过期‘); } }
3.
/** * 身份证正面信息校对 * @param $file 身份证正面图片 * @return bool */ public static function check_idcard_face_message($param) { if ($param[‘idcard_b‘]) { $file = get_image_url($param[‘idcard_b‘]); } else { return false; } //调取阿里身份认证api获取身份证信息 $data = AutoRecognition::face($file); //dump($data);exit; if($data[‘data‘]->num == $param[‘idnum‘]){ return true; }else{ return false; } } /** * 身份证反面信息校对 * @param $file 身份证反面图片-国徽面 * @return bool */ public static function check_idcard_back_message($param) { if ($param[‘idcard_a‘]) { $file = get_image_url($param[‘idcard_a‘]); } else { return false; } //调取阿里身份认证api获取身份证信息 $data = AutoRecognition::back($file); //dump($data);exit; $end_date = $data[‘data‘]->end_date;//提取身份证过期时间 $y = substr($end_date,0,4);//截取年 $m = substr($end_date,4,2);//截取月 $d = substr($end_date,6,2);//截取日 $last_date_unix = strtotime($y.‘-‘.$m.‘-‘.$d);//身份证截止日时间戳 $today_unid = strtotime(date(‘Y-m-d‘));//今日时间戳 //身份证截止日时间戳 > 今日时间戳,身份证未过期,返回true if($last_date_unix > $today_unid){ return true; } else { return false; } }
