1.1 项目介绍
基于laravel框架 微信小程序支付v3版本，支付请求、支付回调、退款请求、退款回调
1.2 配置
在laravel的配置config/app.php中的provide添加```Mjy191\LaravelWxPayV3\ServiceProvider::class``
运行命令php artisan vendor:publish --provider="Mjy191\LaravelWxPayV3\ServiceProvider"发布配置config/wx.php
配置微信小程序的支付
return [
// 小程序的appid
'appAPPID'=>'xxxxxx',
// 商户号
'payMCHID'=>'xxxxxx',
// v2的key
'sk'=>'xxxxxx',
// v3的key
'skv3'=>'xxxxxx',
// 证书序列号
'xlid'=>'xxxxxx',
// 支付证书存放在app/Common/wxCert目录下
'certPath'=>'/app/Common/wxCert/',
// 支付回调地址
'payNotifyUrl'=>'/api/wx/paynotify/',
// 退款回调地址
'refundsNotifyUrl'=>'/api/wx/refundsnotify/',
];
在routes/api.php新增支付回调地址、退款回调地址
Route::post('wx/paynotify/{payNum}',[\App\Http\Controllers\Api\WxController::class,'paynotify']);
Route::post('wx/refundsnotify/{payNum}',[\App\Http\Controllers\Api\WxController::class,'refundsnotify']);
在控制器
namespace App\Http\Controllers\Api;
use App\Http\Controllers\Controller;
use Mjy191\LaravelWxPayV3\WxPayV3;
class WxController extends Controller
{
/**
* 微信支付回调
*/
public function paynotify(WxPayV3 $wxPayV3)
{
return $wxPayV3->notify(function($res){
// 解密后的消息$res，可以参考下面
//处理订单业务逻辑
});
}
/**

*/
public function refundsnotify(WxPayV3 $wxPayV3){
return $wxPayV3->refundsNotify(function($res){
//解密消息$res，可以参考下面

namespace App\Exceptions;
use Mjy191\Tools\Tools;
use Exception;
class ApiException extends Exception
{
/**
* 转换异常为 HTTP 响应
*
* @param \Illuminate\Http\Request
* @return \Illuminate\Http\Response
*/
public function render($request)
{
return response()->json(Tools::returnData(null,$this->getCode(),$this->getMessage()))->setEncodingOptions(JSON_UNESCAPED_UNICODE);
}
}
