与我以前的存储功能相比,try/catch方法不起作用。请进一步阅读。您可以捕获它在找不到时抛出的异常
try {
$customer = Customer::findOrFail($customer_id);
} catch(\Exception $exception){
dd($exception);
$errormsg = 'No Customer to de!' . $exception->getCode();
return Response::json(['errormsg'=>$errormsg]);
}
$result = $customer->delete();
if ($result) {
$customer_response['result'] = true;
$customer_response['message'] = "Customer Successfully Deleted!";
} else {
$customer_response['result'] = false;
$customer_response['message'] = "Customer was not Deleted, Try Again!";
}
return json_encode($customer_response, JSON_PRETTY_PRINT);
