php支付宝手机网页支付类实例_php实例

本文实例讲述了php支付宝手机网页支付类。分享给大家供大家参考。具体分析如下：

此处注意：

① 该类是用在Yii框架里面的，没有去掉一些框架的东西。
② 本类不能不做任何修改而使用。

1. PHP代码部分如下：

2. 使用方法：

//授权接口请求参数<br />$sum = 0.01; //测试用金额<br />$req_data = '充值';<br />$req_data .= ''.$orderNo.'';<br />$req_data .= ''.$sum.'';<br />$req_data .= ''.Url::toRoute(['payment/return'], true).'';<br />$req_data .= ''.Url::toRoute(['payment/notify'], true).'';<br />$req_data .= ''.Yii::$app->params['alipay']['seller_email'].'';<br />$req_data .= '';<br />$params = [<br />    'service' => 'alipay.wap.trade.create.direct',<br />    'format' => 'xml',<br />    'v' => '2.0',<br />    'partner' => Yii::$app->params['alipay']['partner'], //合作者省份ID<br />    'req_id' => date('Ymdhis'),<br />    'sec_id' => Yii::$app->params['alipay']['sign_type'],<br />    'req_data' => $req_data,<br />];<br /> <br />$alipay = new Alipay();<br />$alipay->key = Yii::$app->params['alipay']['key'];<br />$alipay->alipay_config = $params;<br />$url = $alipay->buildPageUrl();<br />$this->redirect($url);

3. 配置示例：

//支付宝相关配置<br />'alipay' => [<br />        'key' => 'XXXXX',  //交易安全校验码,用于签名的32位密钥<br />        'transport' => 'https',         //消息验证地址使用访问方式<br />        'seller_email' => 'XXXX', //卖家支付宝账号，即收款账户<br />        'service' => 'create_direct_pay_by_user', //接口名称<br />        'partner' => 'XXXX', //合作者省份ID<br />        '_input_charset' => 'utf-8', //参数编码字符集<br />        'sign_type' => 'MD5', //签名方式，不参加签名,目前只能是MD5<br />        //以下两个参数没用<br />        'notify_url' => '', //服务器异步通知页面路径<br />        'return_url' => '', //页面跳转通知页面路径<br />],

希望本文所述对大家的php程序设计有所帮助。
