PHP后台支付的开发:微信支付和支付宝支付
关于支付的流程之类的就不做解释,大家可以自行搜索!
- 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 |
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()

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() {<br> $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!" ); }<br> 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。
