PHP后臺微信支付使用方法
主要為大家詳細介紹了PHP后臺微信支付和支付寶支付開發的相關資料，具有一定的參考價值，感興趣的小伙伴們可以參考一下.
微信支付
項目前提：本人用的是tp框架，PHP語言
下載到微信平臺提供的微信支付接口文件，放在了tp第三方類庫vendor，命名為WxpayAPI
WxpayAPI/lib/WxPay.Api.php 接口訪問類;
WxpayAPI/lib/WxPay.Config.php 配置賬號信息;
WxpayAPI/lib/WxPay.Data.php 數據對象基礎類;
WxpayAPI/lib/WxPay.Exception.php 微信支付API異常類;
WxpayAPI/lib/WxPay.Notify.php 回調基礎類
WxpayAPI/example/WxPay.JsApiPay.php JSAPI支付實現類
1.對源碼進行了部分修改
（1）WxPay.Api.php 里注釋掉
/pic/p>
/pic/p>
/pic/p>
（2）WxPay.Config.php里
需要根據商戶信息對APPID ， MCHID ，KEY ， APPSECRET 進行配置。
（3）WxPay.Data.php 里注釋掉
/pic/p>
/pic/p>
（4）WxPay.JsApiPay.php 里注釋掉
/pic/lib/WxPay.Api.php";
配置好這些，接下來就是我們的重點部分了。
2.在訂單控制器GoodsController.class.php有訂單函數sure（）和回調信息函數 Callback_url（）
/**
* 提交訂單函數
*/
public function sure() {
$o_model = D("Wine/Orders");
if (IS_AJAX) {
$data = I("post.");
if ($o_model->create($data)) {
if (!sp_check_verify_code()) {
$this->error("驗證碼錯誤！");
}
#生成隨機訂單號
$order_code = 'O' . date('YmdHis') . $o_model->get_order_code(4);
while ($o_model->findone(array("order_code" => $order_code))) {
$order_code = 'O' . date('YmdHis') . $o_model->get_order_code(4);
}
$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();
$data['update_time'] = time();
if ($data['pay_id'] == 1) {
$data['order_status'] = 11; /pic/p>
$data['status'] = '1';
} else {
$data['order_status'] = 10; /pic/p>
$data['status'] = '1';
}
/pic/p>
$this->Callback_url($data);
} else {
$this->error($o_model->getError());
}
} else {
$this->error($o_model->getError());
}
}
/**
* 回調信息函數
* @param type $data
*/
public function Callback_url($data) {
$o_model = D("Wine/Orders");
$add_id = $o_model->add($data);
if (!$add_id) {
$this->error("訂單提交失敗，請稍后重試！");
}
if ('4' == $data['pay_id']) {
if ('4' == $data['pay_id']) {
/pic/p>
$msg = '正在為您跳轉到微信支付頁面，請等待……';
$url = "/index.php/wine/wxpay/index/?o_id=$add_id";
}
$this->success("訂單提交成功！" . $msg, $url);
}
