详解用vue.js和laravel实现微信支付

注：此项是微信公众号开发，请在往下看之前，先实现网页微信授权登陆功能，具体参看我简书的另一篇文章：//www.Vevb.com/article/117004.htm

1.打开app/config/wechat.php，配置微信支付参数：

  /*   * 微信支付   */   'payment' => [     'merchant_id'    => env('WECHAT_PAYMENT_MERCHANT_ID', 'your-mch-id'),//商家号ID，请将其放在.env文件中     'key'        => env('WECHAT_PAYMENT_KEY', 'key-for-signature'),//商家支付key，请将其放在.env文件中     'cert_path'     => env('WECHAT_PAYMENT_CERT_PATH', storage_path('app/public/apiclient_cert.pem')), //微信支付证书apiclient_cert.pem的绝对路径，我放在storage/app/public/下     'key_path'      => env('WECHAT_PAYMENT_KEY_PATH', storage_path('app/public/apiclient_key.pem')),   //微信支付证书apiclient_key.pem的绝对路径，我放在storage/app/public/下径     // 'device_info'   => env('WECHAT_PAYMENT_DEVICE_INFO', ''),     // 'sub_app_id'   => env('WECHAT_PAYMENT_SUB_APP_ID', ''),     // 'sub_merchant_id' => env('WECHAT_PAYMENT_SUB_MERCHANT_ID', ''),     // ...   ],

以上参数，请依照自己的情况配置，请勿直接拷贝代码！

2.配置微信支付和回调路由

//以下路由我放在api.php路由里，如果你放在web.php路由，请自行调整！Route::middleware('api')->post('wxpay','BillsController@wxpay');Route::middleware('api')->post('wx_notify','BillsController@wxnotify');

3.在相应的控制器里创建wxpay的方法

 /**  * 这是我自己项目的内部代码示例，具体根据自己的业务逻辑调整，切不可直接拷贝！  */  public function wxpay(Request $request)  {    //本实例传递的参数为user_id 和 broadcast_id，具体    if($request->has('user_id') && $request->has('broadcast_id')){      $out_trade_no = md5(Carbon::now().str_random(8));      $user_id = $request->get('user_id');      $broadcast_id = $request->get('broadcast_id');      $num = $request->get('num');      $flag = $request->get('flag');      $openid = $this->user->getOpenid($user_id);      $broadcast = $this->broadcast->getById($broadcast_id);      $speaker_id = $broadcast->speaker_id;      $body = $broadcast->title;      $detail = '';      $paid_at = null;      $status = 'pre_paid';      $amount = ($broadcast->price)*$num;      $attributes = [        'trade_type'    => 'JSAPI', // JSAPI，NATIVE，APP...        'body'       => $body,         'detail'      => $detail,        'out_trade_no'   => $out_trade_no,        'total_fee'    => $amount, // 单位：分        'notify_url'    => $_ENV['APP_URL'].'/api/wx_notify', // 支付结果通知网址，如果不设置则会使用配置里的默认地址        'openid'      => $openid, // trade_type=JSAPI，此参数必传，用户在商户appid下的唯一标识，        // ...      ];      $order = new Order($attributes);      $result = $this->wechat->payment->prepare($order);      if ($result->return_code == 'SUCCESS' && $result->result_code == 'SUCCESS'){        //创建预订单        $param = [          'out_trade_no'=>$out_trade_no,          'user_id'=>$user_id,          'broadcast_id'=>$broadcast_id,          'speaker_id'=>$speaker_id,          'body'=>$body,          'detail'=>$detail,          'paid_at'=>$paid_at,          'amount'=>$amount,          'flag'=>$flag,          'status'=>$status,          'num'=>$num        ];        $this->bill->store($param);        //返回        $prepayId = $result->prepay_id;        $config = $this->wechat->payment->configForPayment($prepayId,false);        return response()->json($config);      }    }  }
