Question

我的HTML表单定义如下：

<form action="{{route('save.checkout')}}" method="POST">
  {{csrf_field()}}
  <input name="amount" type="hidden" value="{{session()->get('cart')->totalprice}}">
  <div class="cart_navigation">
    <a class="continue-btn" href="#">
      <i class="fa fa-arrow-left"> </i>&nbsp; خرید را ادامه دهید
    </a> 
    <a class="checkout-btn" href="{{route('save.checkout')}}">
      <i class="fa fa-check"></i> ادامه به  پرداخت
    </a>
  </div>
</form>

提交表单时抛出以下错误：

The GET method is not supported for this route. Supported methods: POST.

我的路线是：

route::post('/savecheckout','BasketController@checkout')->name('save.checkout');

和结帐功能：

public function checkout(Request $request){
  $user = auth()->user()->id;
  $order = new order();
  $order->user_id = $user;
  $order->amount = $request->input('amount');
  $order->status = 0;
  $order->save();
  $order = order::where('status' ,0)->where('user_id', $user)->first();
  return view('checkout.index', compact('order'));
}

Answer 1

我解决了这个问题。我更改了按钮类型以提交

，这是一个愚蠢的错误

如果您是从Laravel开始的，那么我想为将来的项目做出一些贡献，以使您的编程更好，更安全。

始终验证您的输入
使用try＆catch块
向用户显示适当的错误消息，以便您也可以将来进行调试。

所以修改后的代码如下：

public function checkout(Request $request){
    // use Validator; (add this after namespace to import validator)
    $validator = Validator::make($request->all(),[
        'user_id' => 'required|integer|max:11',
        'amount' => 'required|numeric',
        'status' => 'sometimes|integer|max:1',
    ]);

    if($validator->fails()) {
        return back()->withErrors($validator);
    }
    try {
        $user = auth()->user()->id;
        $order = new order();
        $order->user_id = $user;
        $order->amount = $request->input('amount');
        $order->status = 0;
        $order->save();
        $request->session()->flash('message', 'Order Successfully Created');
        $order = order::where('status' ,0)->where('user_id', $user)->first();
        return view('checkout.index', compact('order'));
    } catch (\Exception $e){
        dd($e->getMessage()); // it will show the error message with, you can replace this block with redirect code or anything else..
    }
}

用于在结帐> index.blade.php模板中的代码下面的前端使用中显示错误和成功消息（仅是示例代码，您可以使用自己的CSS和样式使其更出色）

@if(session()->has('message'))
    <div class="alert alert-success">
        {{ session()->get('message') }}
    </div>
@endif
@if(count($errors) > 0)
    <div class="note note-error">
        <h4>Error..!!</h4>
        <p>
            @foreach($errors->all() as $error)
                <div class="alert alert-danger fade in m-b-15">
                <i class="fa fa-chevron-right"></i>
                {{ $error }}
                <span class="close" data-dismiss="alert">&times;</span></div>
            @endforeach
        </p>
    </div>
@endif

PHP路由：此路由不支持GET方法。支持的方法：POST
