laravel安装laravel-wechat 实现微信授权登录

一.下载laravel-wechat

https://packagist.org/packages/overtrue/laravel-wechat

二. 使用composer安装laravel-wechat

composer require "overtrue/laravel-wechat:~4.0"

三.配置

在 config/app.php 注册 ServiceProvider 和 Facade (Laravel 5.5 + 无需手动注册)

'providers' => [
    // ...
    Overtrue\LaravelWeChat\ServiceProvider::class,
],
'aliases' => [
    // ...
    'EasyWeChat' => Overtrue\LaravelWeChat\Facade::class,
],

创建配置文件：

php artisan vendor:publish --provider="Overtrue\LaravelWeChat\ServiceProvider

1.修改应用根目录下的 config/wechat.php 中对应的参数即可。

WECHAT_LOG_LEVEL=info  //日志级别 最好和laravel同级
WECHAT_LOG_FILE=/var/log/coupon/report.log  //日志保存文件 最好和laravel 统一
WECHAT_OFFICIAL_ACCOUNT_APPID=申请的appid
WECHAT_OFFICIAL_ACCOUNT_SECRET=申请的appsecret
WECHAT_OFFICIAL_ACCOUNT_TOKEN=
WECHAT_OFFICIAL_ACCOUNT_AES_KEY=

     // return $this->success(['c' => $this->wxapp_config, 'b' => $app, 'f' => $data, 'userInfo' => ]);

laravel使用EasyWeChat 统一下单

use EasyWeChat\Factory;
private $app;
public function __construct()
{

  $config = config('wechat.payment.default');
  $this->app = Factory::payment($config);
}
public function payment(PayRequest $request){
  $isContract = true;
  $result = $this->app->order->unify([
  'body' => '用户下单',
  'out_trade_no' => $order_no,
  'total_fee' => 10,
//           'spbill_create_ip' => '123.12.12.123', // 可选，如不传该参数，SDK 将会自动获取相应 IP 地址
  'notify_url' =>  config('wechat.payment.default.notify_url'), // 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
  'trade_type' => 'JSAPI', // 请对应换成你的支付方式对应的值类型
  'openid' => Auth::user()->openid,
  ], $isContract);
  //注意
  1、如果支付时出现报错，timestame 参数问题。这是 easywechat 底层文件出错了。

  if ($result['return_code'] == 'SUCCESS' && $result['result_code'] == 'SUCCESS'){
      $config['timeStamp'] = $config['timestamp'];
     unset($config['timestamp']);
     return $this->success( $config);
}else{
      return $this->fail('支付失败');
}
2、如果签名失败
if ($result['return_code'] == 'SUCCESS' && $result['result_code'] == 'SUCCESS'){
      $prepayId = $result['prepay_id'];
      $jssdk =$this->app->jssdk;
      $config = $jssdk->sdkConfig($prepayId);
      $config['timeStamp'] = $config['timestamp'];
     unset($config['timestamp']);
     return $this->success( $config);
}else{
      return $this->fail('支付失败');
}

}

申请退款

退款方式分为两种
第一种：根据微信订单号退款

// 参数分别为：微信订单号、商户退款单号、订单金额、退款金额、其他参数
$app->refund->byTransactionId(string $transactionId, string $refundNumber, int $totalFee, int $refundFee, array $config = []);

// Example:
$result = $app->refund->byTransactionId('transaction-id-xxx', 'refund-no-xxx', 10000, 10000, [
    // 可在此处传入其他参数，详细参数见微信支付文档
    'refund_desc' => '商品已售完',
]);

第二种：根据商户订单号退款

// 参数分别为：商户订单号、商户退款单号、订单金额、退款金额、其他参数
$app->refund->byOutTradeNumber(string $number, string $refundNumber, int $totalFee, int $refundFee, array $config = []);

// Example:
$result = $app->refund->byOutTradeNumber('out-trade-no-xxx', 'refund-no-xxx', 20000, 1000, [
    // 可在此处传入其他参数，详细参数见微信支付文档
    'refund_desc' => '退运费',
]);
