绑定回调路由 routes/api.php

Route::any('/gateway/wxpay/callback', 'PayController@callback')->name('pay.callback');

注意前一篇文章的添加 .env 与此处路由的 URL 要保持一致。：

WECHAT_PAYMENT_NOTIFY_URL=https://www.mysite.com/gateway/wxpay/callback

app/Http/Controllers/PayController.php 添加 callback 方法

/**     * 微信支付回调     *     * @return Response     */    public function callback()    {        return $this->buy_repository->callback();    }

appRepositoriesBuyRepository.php 添加 callback 逻辑

public function callback()    {        $this->wxpay = app('easywechat.payment');        return $this->wxpay->handlePaidNotify(            function ($message, $fail) {                if ($message['result_code'] === 'FAIL') {                    logger()->warning('WXPAY_CALLBACK', ['FAIL', $message]);                    return true;                } else if ($message['return_code'] === 'SUCCESS') {                    // TODO: 你的发货逻辑                    return true;                }            }        );    }
