Question

我有一个奇怪的错误，没有'Access-Control-Allow-Origin'标题。我知道我必须给予原始域（客户端）一些权限才能访问服务器，并且我可以正常处理其他一些请求。但是当涉及到另一个要调用的函数时，它只会说'No-Control-Control-Allow-Origin'标题。

我的客户端托管于heroku，服务器托管在godaddy ......

当错误显示时，这是函数：

public function store(Request $request)
{

    $ffSpending = new FriendsFamilySpending();
    $ffSpending->user_id = Auth::user()->id;
    $ffSpending->team_id = Auth::user()->student->team_id;
    $ffSpending->management_units = $request->input('management_units');
    $ffSpending->sales_units = $request->input('sales_units');
    $ffSpending->product_units = $request->input('product_units');
    $ffSpending->ip_units = $request->input('ip_units');

    $ffSpendingRules = array(
        'management_units' => 'required',
        'sales_units' => 'required',
        'product_units' => 'required',
        'ip_units' => 'required'
    );

    $ffSpendingValidator = \Validator::make($ffSpending->getAttributes(), $ffSpendingRules);

    if ($ffSpendingValidator->passes()) {


        $team = Team::find($ffSpending->team_id);
        $currentBalance = $this->teamService->checkBalance($team);

        //Baseline costs
        $BASELINE = FriendsFamilySpending::BASELINE;
        //Get Prices for each unit
        $IP_ONE_TIME_COST = OperationalExpensePrice::getPrice(OperationalExpense::IP, $request->input('ip_units'), OperationalExpenseSerie::FF);//one-time IP costs
        $MANAGEMENT = OperationalExpensePrice::getPrice(OperationalExpense::MANAGEMENT, $request->input('management_units'), OperationalExpenseSerie::FF);
        $SALES = OperationalExpensePrice::getPrice(OperationalExpense::SALES, $request->input('sales_units'), OperationalExpenseSerie::FF);
        $PRODUCT = OperationalExpensePrice::getPrice(OperationalExpense::PRODUCT, $request->input('product_units'), OperationalExpenseSerie::FF);

        //Monthly Costs
        $quartlyCosts = $BASELINE + $MANAGEMENT + $SALES + $PRODUCT;

        $newBalance = $currentBalance;
        $workingMoney = $newBalance - $IP_ONE_TIME_COST;

        $minimumMonth = 12; // the minimum amount of time they must be able to afford (Staging Day  = 12 months)
        //Calculate how many months they (team) can survive
        $survivingMonths = 0;
        while ($workingMoney >= $quartlyCosts) {
            $workingMoney = $workingMoney - $quartlyCosts; //deduct monthly costs from the current working money
            $survivingMonths = $survivingMonths + 3; // quartly spending
            if ($survivingMonths > 24) { // team survives the whole staging and deal day
                break;
            }
        }

        // month to minute - Conversation ratio
        $monthToMinute = 6.25; // (75min / 12month) = 6.25min a month
        $totalMinutes = $survivingMonths * $monthToMinute;
        $minMinutes = 75; //the minimum amount of time they must be able to afford

        //Check if team makes it till the deal day
        if ($survivingMonths < $minimumMonth) {
            return response()->json(['message' => 'With your current spending plan, you will not make it to deal day. Please try again with less spending plan. Currently you run out of money after ' . $totalMinutes . ' minutes. You have to survive at least 75 minutes."', 'success' => false, 'status' => 500, 'data' => null]);
        }

        $ffSpendingRes = $this->ffSpendingService->save($ffSpending);
        if ($ffSpendingRes) {
            $this->ffSpendingService->score(Auth::user()->student->team->class_id); // update ff spending scoring
            $this->ffSpendingService->updateTotalScore(Auth::user()->student->team->class_id);

            //Update balance
            $team = Team::find($ffSpending->team_id);
            $this->teamService->updateBalance($team, $workingMoney);


            if ($survivingMonths >= $minimumMonth && $survivingMonths < 24) {
                $survivingMonthsAfterStagingDay = $survivingMonths - $minimumMonth;
                $survivingMonthsAfterStagingDayToMinute = $survivingMonthsAfterStagingDay * $monthToMinute;
                $outOfMoney = new OutOfMoney();
                $outOfMoney->team_id = Auth::user()->student->team_id;
                $outOfMoney->stage = OutOfMoney::$FF_SPENDING;
                $outOfMoney->is_running_out_of_money_on_deal_day = 1;
                $outOfMoney->month = $survivingMonthsAfterStagingDay;
                $outOfMoney->minutes = $survivingMonthsAfterStagingDayToMinute;
                $outOfMoney->monthly_cost = $quartlyCosts;
                $outOfMoney->save();
            } else {
                $outOfMoney = new OutOfMoney();
                $outOfMoney->team_id = Auth::user()->student->team_id;
                $outOfMoney->stage = OutOfMoney::$FF_SPENDING;
                $outOfMoney->is_running_out_of_money_on_deal_day = 0;
                $outOfMoney->monthly_cost = $quartlyCosts;
                $outOfMoney->save();
            }
            return response()->json(['message' => 'Success', 'success' => true, 'status' => 200, 'data' => $ffSpending]);
        } else {
            return response()->json(['message' => 'Error', 'success' => false, 'status' => 500, 'data' => null]);
        }
    } else {
        return response()->json(['message' => 'Validation Failed', 'success' => false, 'status' => 400, 'data' => array('class' => $ffSpendingRules)]);
    }

注意：如果我更改了函数并使其变得简单，例如返回'test'，它就不再显示原始访问错误。我想知道函数是否有任何问题，为什么不显示实际错误，但它显示cors错误。

有什么建议吗？

正在发生的是ORIGINS请求即将进入并被拒绝，因为它不在您允许的方法中。

'allowedMethods' => ['GET', 'POST', 'PUT', 'DELETE', 'ORIGINS']

您还希望将allowedOrigins设置为某种内容。

我总是使用MDN作为参考。

即使您来自同一域的其他请求正在运行，也不会出现“Access-Control-Allow-Origin”标头
