国外的支付集成接入。
只使用基础的卡支付，跟PayPal支付。
braintree 有沙盒环境可以申请测试，有php sdk包直接下载调用，非常简单。
1，声明配置信息
private $_debug = false; private $_pay_method = 'braintree'; private $_config = null; private $_gateway = null; private $_merchantAccountId = [ 'usd' => 'xxxUSD' ]; //货币对应的merchantAccountId，建议自定义该值， private $_customerPre = ''; //用户名前缀，用户生成顾客id， private $_customerId = null; public $_err = '';
public function __construct() { if( $this->_debug ) { $this->_config['environment'] = 'sandbox'; $this->_config['merchantId'] = '6xqytmznhcczwwph'; $this->_config['publicKey'] = 'ks2j7rg234tq7fm7'; $this->_config['privateKey'] = '13012ef64ae8b95443f08226ac25c890'; $this->_merchantAccountId['usd'] = ''; //测试使用默认，也可以自定义， $this->_customerPre = 'test1'; }else { $this->_config['environment'] = 'production'; $this->_config['merchantId'] = ''; $this->_config['publicKey'] = ''; $this->_config['privateKey'] = ''; $this->_customerPre = 'Pro'; }
//实例化gate类，为基础类 import("Pay.braintree_macaroon_app.lib.Braintree", VENDOR_PATH, '.php' ); $this->_gateway = new Braintree_Gateway( [ 'merchantId' => $this->_config['merchantId'], 'publicKey' => $this->_config['publicKey'], 'privateKey' => $this->_config['privateKey'], 'environment' => $this->_config['environment'], 'timeout' => 2, ] ); }
2，生成并获取顾客id，顾客id可以保留顾客的支付方式，方便其下次直接已购买，而不用重复输入卡或者paypal信息
/** create table uro_braintree_uid( id int unsigned not null auto_increment, uid int unsigned not null default 0 comment '本站id', bid varchar(256) not null default '' comment 'braintree customerid', primary key (`id`), unique key (`uid`) ) engine innodb charset utf8 comment 'braintree 用户对应关系表，creditcard，paypal等信息以后可加字段'; * 获取、创建braintree 用户， * author liuxiaodong * date 2018/7/31 15:38 * @param $uid * @return string */ private function getCreateCustom( $uid ) { $model = M('braintreeUid'); $bid = $model->where( ['uid' => $uid] )->getField( 'bid' ); if( $bid ) return $bid; try{ $res = $this->_gateway->customer()->create( [ 'id' => $this->_customerPre . $uid ] ); if( $res->success ) { $bid = $res->customer->id; if( !$model->add( ['uid' => $uid, 'bid' => $bid] ) ) $this->_warnNotice( 'send -- into db error', '数据入库失败，入库数据为 = '. json_encode( ['uid' => $uid, 'bid' => $bid] ) . ',err =' . $model->getLastSql() .'|'. $model->getDbError() ); }else $this->_warnNotice( 'send -- res error', '请求braintree服务器，生成用户信息失败 = ' . json_encode( $res ) ); return $bid; }catch ( Exception $e ) { $this->_warnNotice( 'send -- createCustom', '请求braintree服务器，抛出异常' . json_encode( $e ) ); return ''; } }
3，获取客户端token，同时可以追加自己的信息，比如这边追加返回了订单的信息，让客户端回传，
/** * 初始化订单信息，返回 clientoken，orderinfo 信息 * author liuxiaodong * date 2018/7/27 17:56 * @param array $params * @return array */ public function send( $order ) { $this->_customerId = $this->getCreateCustom( $order['braintree']['uid'] ); $this->_warnNotice( 'send -- getClientToken', 'get request', 'debug' ); $res = ['clientoken' => '', 'transaction' => []]; try{ $res['clientoken'] = $this->_gateway->clientToken()->generate( [ 'customerId' => $this->_customerId ] ); }catch ( Exception $e ) { $this->_warnNotice( 'send -- getClientToken', '错误信息：格式化exception ==' . json_encode( $e ) . ' , errmsg = ' . $e->getMessage() ); return []; } $res['transaction'] = $this->_encrypt( $order['braintree'] ); $this->_warnNotice( 'send -- getClientToken', 'send request' . json_encode( $res ), 'debug' ); return $res; }
4，支付, 是客户端请求后，请求braintree直接获取支付结果，做逻辑操作。
//此接口做支付 public function notify( $params ) { $this->_warnNotice( 'notify', '参数' . json_encode( $params ), 'debug' ); if( empty( $params['nonce'] ) || empty( $params['transaction'] ) ) { $this->_warnNotice( 'notify', '请求参数异常 无nonce、transaction， 参数为 == ' . json_encode( $params ) ); $this->_err = 'invalid params'; return false; } $transaction = $this->_decrypt( $params['transaction'] ); if( empty( $transaction ) || !is_array( $transaction ) ) { $this->_warnNotice( 'notify', '参数异常, 无transaction == ' . json_encode( $params ) ); $this->_err = 'invalid params'; return false; } //读取订单信息 $model = D('Common/OrderRetail'); $order = $model->find( $transaction['oid'] ); if( !$order ) { $this->_err = 'invalid order info'; $this->_warnNotice( 'notify', '读取订单信息异常 == ' . json_encode( $transaction ) . ' from ' . $params['client'] . ' order == ' . json_encode( $order ) . ' sql ==' . $model->getLastSql() ); return false; } if( $order['amount'] != $transaction['amount'] ) { $this->_err = 'check amount error'; $this->_warnNotice( 'notify', '核对订单金额失败 == ' . json_encode( $transaction ) . ' from ' . $params['client'] . ' order amount = ' .$order['amount'] ); return false; } $amount = $transaction['amount']; if( $this->_debug ) $amount = 0.01; //debug下请保证前端使用的金额也是0.01 //商品信息 foreach ( $transaction['goods'] as $v ) { $lineItems[] = [ 'description' => $transaction['oid'], // Maximum 127 characters 'kind' => 'debit', 'name' => mb_substr( $v['product_info']['name'], 0, 30, 'utf8' ) . '...', 'productCode' => $v['product_id'], //gid 'quantity' => $v['num'], 'totalAmount' => $v['product_info']['price'] * $v['product_info']['num'], 'unitAmount' => $v['product_info']['price'], 'url' => '' ]; } $this->_customerId = $this->getCreateCustom( $transaction['uid'] ); $trans = [ 'amount' => $amount, //总金额 'merchantAccountId' => $this->_merchantAccountId['usd'], //merchantAccountId 'paymentMethodNonce' => $params['nonce'], 'lineItems' => $lineItems, 'orderId' => $transaction['oid'], //自定义的值 'customerId' => $this->_customerId, 'options' => [ 'submitForSettlement' => true, //申请结算， ] ]; $this->_warnNotice( 'notify', 'sale 发送请求' . json_encode( $trans ) . 'from ' . $params['client'], 'debug' ); $res = $this->_gateway->transaction()->sale( $trans ); $this->_warnNotice( 'notify', 'sale 结果' . json_encode( $res->success ) . 'from ' . $params['client'], 'debug' ); if( $res->success ) { $trance = $res->transaction;
//个人逻辑
return true; }else { $this->_err = $res->message . '('.$res->transaction->processorResponseCode.')'; $this->_warnNotice( 'notify', '请求 sale 发送交易抛出异常, 简讯 '.$this->_err.' 详情 == ' . json_encode( $res ), 'error' ); return false; } }
5, 其他附加方法，报警；加解密
/** * 获取客户端token * author liuxiaodong * date 2018/7/26 15:57 * @return array */ public function getClientToken() { try{ $token = $this->_gateway->clientToken()->generate(); return [true, $token]; }catch ( Exception $e ) { $this->_warnNotice( 'getClientToken', '获取clienttoken 失败。。' . json_encode( $e ), 'error' ); return [false, $e->getMessage()]; } } private function _warnNotice( $action, $msg, $level = 'error' ) { if( $level == 'debug' && !$this->_debug ) return; $msg .= PHP_EOL; Log::write( $action . ' -- ' . $msg, $level, '', C('LOG_PATH') . 'braintreeErr/' . date( 'Y-m-d' ) . '.log' ); if( !$this->_debug ) { $email = new AliyunEail(); $email->sendEmail( 'email...', 'braintree pay error', date( 'Y-m-d H:i:s' ) . '<br />' . $msg ); } } /** * Encrypts the input text using the cipher key * * @param $input * @return string */ private function _encrypt( Array $input) { $input = json_encode( $input ); // Create a random IV. Not using mcrypt to generate one, as to not have a dependency on it. $iv = substr(uniqid("", true), 0, self::IV_SIZE); // Encrypt the data $encrypted = openssl_encrypt($input, "AES-256-CBC", 'key', 0, $iv); // Encode the data with IV as prefix return base64_encode($iv . $encrypted); } /** * Decrypts the input text from the cipher key * * @param $input * @return string */ private function _decrypt($input) { // Decode the IV + data $input = base64_decode($input); // Remove the IV $iv = substr($input, 0, self::IV_SIZE); // Return Decrypted Data $output = openssl_decrypt(substr($input, self::IV_SIZE), "AES-256-CBC", 'key', 0, $iv); return json_decode( $output, true ); } public function getError() { $msg = 'err: '; $msg .= $this->_err ? $this->_err : 'server fail'; return $msg; }

报警： （该错误是前段生成的金额跟后端的不一致导致，多是debug的时候）
