支付宝身份认证（刷脸）小程序PHP

支付宝小程序的身份认证，需要添加支付宝（支付宝身份验证）能力，签约成功后可以开始了

TP代码

public function aliUserCode(): array
{
    // 引入支付宝SDK
    vendor('.alipayapp.aop.AopClient');
    vendor('.alipayapp.aop.request.AlipayUserCertifyOpenInitializeRequest');
    vendor('.alipayapp.aop.request.AlipayUserCertifyOpenCertifyRequest');
    $aop = new \AopClient();
    $data = Payment::read(12, 1, true); // 数据库保存的支付宝配置信息，没有的可以忽略
    $aop->gatewayUrl = 'https://openapi.alipay.com/gateway.do';
    $aop->appId = $data['pay_config']['app_id']; // 支付宝APPID
    $aop->rsaPrivateKey = $data['pay_config']['private_key']; // 应用私钥
    $aop->alipayrsaPublicKey = $data['pay_config']['ali_public_key']; // 支付宝公钥
    $aop->apiVersion = '1.0';
    $aop->signType = 'RSA2';
    $aop->postCharset='utf-8';
    $aop->format='json';
    // 身份认证初始化服务
    $request = new \AlipayUserCertifyOpenInitializeRequest  ();
    $order_no = time().rand(1111,9999);
    $newsigndata=array();
    $newsigndata['outer_order_no']= $order_no;
    $newsigndata['biz_code']="FACE";
    $newsigndata['identity_param']['identity_type']="CERT_INFO";
    $newsigndata['identity_param']['cert_type']="IDENTITY_CARD";
    $newsigndata['identity_param']['cert_name']= '小明'; // 真实姓名
    $newsigndata['identity_param']['cert_no']= '4418219999999999999'; // 证件号码
    $newsigndata['merchant_config']['return_url']= url('api/payment/fundAuthNotify');
    $newsigndata['face_contrast_picture']="xydasf==";
    $tosign=\json_encode($newsigndata);
    $request->setBizContent($tosign);
    $result = $aop->execute ($request);
    $responseNode = str_replace(".", "_", $request->getApiMethodName()) . "_response";
    $resultCode = $result->$responseNode->code;
    if(empty($resultCode) || $resultCode != 10000){
            return '失败';
    }
    // (身份认证开始认证)
    $certify_id = $result->$responseNode->certify_id;
    $request = new \AlipayUserCertifyOpenCertifyRequest();
    $tousersigndata = ['certify_id'=>$certify_id];
    $tousersign=\json_encode($tousersigndata);
    $request->setBizContent($tousersign);
    $result = $aop->pageExecute ( $request, 'get');  // 加get 返回url链接 ，不加返回form表单
    return $result; // 如果是小程序的话就直接返回url链接，客户端的话就返回表单
}

认证场景码（biz_code）这个参数有多种选择

identity_param：需要验证的身份信息参数，格式为 json

         cert_type：证件类型，必填，当前支持  （IDENTITY_CARD：身份证）（HOME_VISIT_PERMIT_HK_MC：港澳居民来往内地通行证）（HOME_VISIT_PERMIT_TAIWAN：台湾居民来往内地通行证）（RESIDENCE_PERMIT_HK_MC：港澳居民居住证）（RESIDENCE_PERMIT_TAIWAN：台湾居民居住证）
