我正在尝试使用Laravel创建一个简单的LMS系统。我在这里关注YouTube指南和QuickLMS存储库:https://github.com/LaravelDaily/QuickLMS/。大多数应用程序都可以正常运行,但是我想更改并删除其中一个功能。
我在为学生或用户分配课程的特定功能时遇到困难。每当学生在首页上打开课程时,顶部都会显示一个按钮,显示“购买课程”,这会加载Stripe弹出窗口供学生付款。付款完成后,会在course_student表中将课程分配给学生。
我从中借用的代码使用Stripe支付课程费用。我希望该按钮是“注册课程”按钮,而不是付款按钮。这样,当学生进入课程时,将显示一个注册课程的按钮,该按钮将学生添加到course_student表中,而无需任何付款信息。
CoursesController.php:
public function payment(Request $request)
{
$course = Course::findOrFail($request->get('course_id'));
$this->createStripeCharge($request);
$course->students()->attach(\Auth::id());
return redirect()->back()->with('success', 'Payment completed successfully.');
}
private function createStripeCharge($request)
{
Stripe::setApiKey(env('STRIPE_API_KEY'));
try {
$customer = Customer::create([
'email' => $request->get('stripeEmail'),
'source' => $request->get('stripeToken')
]);
$charge = Charge::create([
'customer' => $customer->id,
'amount' => $request->get('amount'),
'currency' => "usd"
]);
} catch (\Stripe\Error\Base $e) {
return redirect()->back()->withError($e->getMessage())->send();
}
}
course.blade.php:
<form action="{{ route('courses.payment') }}" method="POST">
<input type="hidden" name="course_id" value="{{ $course->id }}" />
<input type="hidden" name="amount" value="{{ $course->price * 100 }}" />
<script
src="https://checkout.stripe.com/checkout.js" class="stripe-button"
data-key="{{ env('PUB_STRIPE_API_KEY') }}"
data-amount="{{ $course->price * 100 }}"
data-currency="usd"
data-name="Quick LMS"
data-label="Buy course (${{ $course->price }})"
data-description="Course: {{ $course->title }}"
data-image="https://stripe.com/img/documentation/checkout/marketplace.png"
data-locale="auto"
data-zip-code="false">
</script>
web.php:
Route::post('course/payment', ['uses' => 'CoursesController@payment', 'as' => 'courses.payment']);
我尝试通过删除对Stripe的任何引用来更改所有这些内容,而是创建一个看起来像这样的新函数:
CoursesController.php:
public function register (Request $request)
{
$this->createSubscription($request);
return redirect()->back()->with('success', 'Payment completed successfully.');
}
private function createSubscription($request)
{
$course = Course::findOrFail($request->get('course_id'));
$course->students()->attach(\Auth::id());
}
但是,这只会从Laravel生成一条“页面已过期”消息,而我不知道如何仅删除“条纹”按钮。
我试图替换整个“付款”功能而没有成功。我认为这是我想要的代码,但是显然它需要进行一些更改才能工作,但是我无法弄清楚:
$course->students()->attach(\Auth::id());
答案 0 :(得分:0)
我自己通过创建两个新功能解决了这个问题: CoursesController.php:
BlockSource
以及Course.blade.php上的以下表格:
private async void ReceiveUdpPackets()
{
await Task.Run(async () =>
{
try
{
while (receivePackets)
{
Log.Info("Listening for UDP packets...");
listener.Client.SetSocketOption(SocketOptionLevel.Udp, SocketOptionName.BlockSource, false);
byte[] bytes = listener.Receive(ref groupEP);
listener.Client.SetSocketOption(SocketOptionLevel.Udp, SocketOptionName.BlockSource, true);
Log.Info($"Received UDP broadcast from {groupEP} :");
Log.Info($"{Encoding.ASCII.GetString(bytes, 0, bytes.Length)}");
var bString = BitConverter.ToString(bytes).Replace("-", "");
Log.Info("UDP ByteString: " + bString);
DecodeByteString(bString);
await Task.Delay(5000);
}
}
catch (Exception ex)
{
Log.Error("There was an issue decoding the UDP packet: " + ex.ToString());
}
});
}
Web.php
public function register (Request $request)
{
$course = Course::findOrFail($request->get('course_id'));
$this->createSubscription($request);
$course->students()->attach(\Auth::id());
return redirect()->back()->with('success', 'Payment completed successfully.');
}
private function createSubscription($request)
{
return;
}
也许可以用更好的方法来完成,但这确实是我想要的。
