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.方法接收参数 idcard_b-身份证正面 idcard_a-身份证国徽面 

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
        $res1 = self::check_idcard_back_message($param);
        if (!$res1) {
            return Response::response(1,'身份证已过期');
        }
    }

 

3.调用工具类验证

/**
     * 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'] != '获取身份信息失败' && $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($data);exit;
        if ($data['data'] != '获取身份信息失败') {
            $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;
            }
        } else {
            return false;
        }

    }
