我有私人和公共職能。私有函數獲取從表單發送的數據，公共函數執行結帳。 private function projectData(Request $request){ // dd($request->all()); // $item = []; // $datat = array_map(function($item){ // return [ // 'name'=>$request->project_id, // 'price'=>$request->budget, // 'desc'=>'Deposit', // 'qty'=>1 // ]; // }, $item); $data = [ 'items'=>[ 'name'=>'Project No.'.$request->project_id ], 'invoice_id' => uniqid(), 'invoice_description' => "Payment for Project No.".$request->project_id." Amount ".$request->budget, 'return_url' => route('payment.success'), 'cancel_url' => route('payment.cancel'), 'total' => $request->budget ]; // dd($data); return $data; } /** * Responds with a welcome message with instructions * * @return \Illuminate\Http\Response */ public function payment() { $data = $this->projectData(); $provider = new ExpressCheckout; $response = $provider->setExpressCheckout($data); dd($response); // $response = $provider->setExpressCheckout($data, true); return redirect($response['paypal_link']); }我收到這個錯誤函數 App\Http\Controllers\PayPalController::projectData() 的參數太少，第 42 行 /var/www/CareerHouse/app/Http/Controllers/PayPalController.php 中傳入的參數為 0，而預期為 1我不知道我做錯了什么以及如何糾正？

由于付款是公共方法并且它會重定向，因此很可能是通過路由調用的。在這種情況下，您可以在付款中注入請求實例，如下所示：
public function payment(Request $request) {
$data = $this->projectData($request);
$provider = new ExpressCheckout;
$response = $provider->setExpressCheckout($data);
dd($response);
// $response = $provider->setExpressCheckout($data, true);
return redirect($response['paypal_link']);
}

private function projectData(){
$request=request();
// dd($request->all());
// $item = [];
// $datat = array_map(function($item){
// return [
// 'name'=>$request->project_id,
// 'price'=>$request->budget,
// 'desc'=>'Deposit',
// 'qty'=>1
// ];
// }, $item);
$data = [
'items'=>[
'name'=>'Project No.'.$request->project_id
],
'invoice_id' => uniqid(),
'invoice_description' => "Payment for Project No.".$request->project_id." Amount ".$request->budget,
'return_url' => route('payment.success'),
'cancel_url' => route('payment.cancel'),
'total' => $request->budget
];
// dd($data);
return $data;
}
/**
* Responds with a welcome message with instructions
*
* @return \Illuminate\Http\Response
*/
public function payment() {
$data = $this->projectData();
$provider = new ExpressCheckout;
$response = $provider->setExpressCheckout($data);
dd($response);
// $response = $provider->setExpressCheckout($data, true);
return redirect($response['paypal_link']);
}
僅當您來自請求時，而不是從請求的函數調用另一個函數時，才可以使用依賴項注入，如果您要這樣做，請嘗試我的方法，或者將您的請求添加到處理此請求的主控制器并傳遞給其他方法。
