PHP开发微信支付和支付宝支付实例

本文主要和大家分享PHP开发微信支付和支付宝支付实例,关于支付的流程之类的就不做解释,大家可以自行在php中文网中搜索哦。

 

  • 微信支付

项目前提:本人用的是tp框架,PHP语言下载到微信平台提供的微信支付接口文件,放在了tp第三方类库vendor,命名为WxpayAPI,

WxpayAPI/lib/WxPay.Api.php 接口访问类;

WxpayAPI/lib/WxPay.Config.php 配置账号信息;

WxpayAPI/lib/WxPay.Data.php 数据对象基础类;

WxpayAPI/lib/WxPay.Exception.php 微信支付API异常类;

WxpayAPI/lib/WxPay.Notify.php 回调基础类

WxpayAPI/example/WxPay.JsApiPay.php JSAPI支付实现类

PHP开发微信支付和支付宝支付实例_第2张图片

1.对源码进行了部分修改

(1)WxPay.Api.php 里注释掉

        //require_once "WxPay.Exception.php";

        //require_once "WxPay.Config.php";

        //require_once "WxPay.Data.php";

  

(2)WxPay.Config.php里

        需要根据商户信息对APPID , MCHID ,KEY , APPSECRET 进行配置。

  

(3)WxPay.Data.php 里注释掉

        //require_once "WxPay.Config.php";

        //require_once "WxPay.Exception.php";

  

(4)WxPay.JsApiPay.php 里注释掉

        //require_once "../lib/WxPay.Api.php";

配置好这些,接下来就是我们的重点部分了。

2.在订单控制器GoodsController.class.php有订单函数sure()和回调信息函数 Callback_url()

5.支付成功跳转到OrderController.class.php ,订单支付完成

 

到此,微信支付流程结束。

  • 支付宝支付

话不多说,直接上代码!

注:1.支付文件是从支付宝上直接拿过来的2.依旧是TP框架
【1】将文件放入第三方类库:

【2】支付业务逻辑

(1)GoodsController.class.php 下提交订单 ajax_sure()

  

public function ajax_sure() {

  $data['order_code'] = $order_code;

  $addr[0] = $_POST['prov'];

  $addr[1] = $_POST['city'];

  $addr[2] = $_POST['dist'];

  $addr[3] = $_POST['area'];

  $data['area'] = serialize($addr);

  $data['create_time'] = time();

  $data['update_time'] = time();

  $data['ip'] = $_SERVER['REMOTE_ADDR'];

   if ($data['pay_id'] == 1) {

          $data['order_status'] = 11; //已付款

          $data['status'] = '1';

   } else {

          $data['order_status'] = 10; //待付款

           $data['status'] = '1';

  }

   //函数调用 返回信息

  $this->Callback_url($data);

}

/**

     * 回调信息函数

     * @param type $data

     */

    public function Callback_url($data) {

        $o_model = D("Wine/Orders");

        $add_id = $o_model->add($data);

        if (!$add_id) {

            $this->error("订单提交失败,请稍后重试!");

        }

        if ('3' == $data['pay_id']) {

            //支付宝支付

            $msg = '正在为您跳转到支付宝支付页面,请等待……';

            $url = U("Pay/doalipay", array('o_id' => $add_id));

        }

        $this->success("订单提交成功!" . $msg, $url);

    }

  

(2)PayController.class.php 下

    /**

     * 支付页面

     */

    public function doalipay() {

        $o_id = I("get.o_id", 0, "intval");

        $info = $this->model->findone(array("a.id" => $o_id, 'a.status' => array('neq', '-1')));

        //10代表订单待支付的状态

        if ($info['order_status'] != 10) {

            $this->error("订单已支付!");

        }

        vendor("Payment.Alipay.Alipay");

        $alipay = new \Alipay();

        $param['order_sn'] = $info['order_code'];

//        $param['order_amount'] = $info['pay_price'];

        $param['order_amount'] = 0.01;//测试支付时,将支付价格设为0.01元,土豪朋友忽略此提示O(∩_∩)O~

        $param['order_subject'] = '支付宝支付测试';

        $param['return_url'] = 'http://' . $_SERVER['SERVER_NAME'] . '/index.php/Wine/Orders/pay_ok/o_id/'.$o_id;

        $return = $alipay->submit($param);

        echo $return;

        exit;

    }

就是这么简单几步,到此,支付宝支付的流程就已经结束了。
