php - Illuminate\Routing\Redirect 类的对象或无法转换为字符串

Question

当我点击一个 PayPal 集成按钮时，它会显示这个错误，我也在 larval 5.7 的标题中写了这个错误

下面是我的控制器代码

class PayPalController extends Controller
{
    /**
     * @var ExpressCheckout
     */
    protected $provider;
    protected $mail = false;

    protected $products = [

        });

        return $invoice;
    }
}

这是我在控制器中使用的代码，其中重定向代码要更改我无法理解

这是我的路线我找不到错误我用这个代码做的错误

Route::get('/payment/{type}','PayPalController@getExpressCheckout');
Route::post('/payment/{type}','PayPalController@getExpressCheckout');
Route::get('/payment-process/{type}','PayPalController@getExpressCheckoutSuccess');
Route::get('/payment-details','PayPalController@getIndex');

Answer 1

首先，我将向您展示如何使用自定义 php 集成 paypal。

1）这是贝宝的html表单。

<!DOCTYPE html>
<html>
<head>
    <meta charset="utf-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <title>Paypal Integration Test</title>
</head>
<body>

    <form class="paypal" action="payments.php" method="post" id="paypal_form">
        <input type="hidden" name="cmd" value="_xclick" />
        <input type="hidden" name="no_note" value="1" />
        <input type="hidden" name="lc" value="UK" />
        <input type="hidden" name="bn" value="PP-BuyNowBF:btn_buynow_LG.gif:NonHostedGuest" />
        <input type="hidden" name="first_name" value="Customer's First Name" />
        <input type="hidden" name="last_name" value="Customer's Last Name" />
        <input type="hidden" name="payer_email" value="[e-mail]" />
        <input type="hidden" name="item_number" value="123456" / >
        <input type="submit" name="submit" value="Submit Payment"/>
    </form>

</body>

2）请求（操作页面）

payment.php 页面将用于处理对 PayPal 的传出请求，并在处理付款后处理传入的响应。

// For test payments we want to enable the sandbox mode. If you want to put live
// payments through then this setting needs changing to `false`.
$enableSandbox = true;

// Database settings. Change these for your database configuration.
$dbConfig = [
    'host' => 'localhost',
    'username' => 'user',
    'password' => 'secret',
    'name' => 'example_database'
];

// PayPal settings. Change these to your account details and the relevant URLs
// for your site.
$paypalConfig = [
    'email' => '[e-mail]',
    'return_url' => 'http://example.com/payment-successful.html',
    'cancel_url' => 'http://example.com/payment-cancelled.html',
    'notify_url' => 'http://example.com/payments.php'
];

$paypalUrl = $enableSandbox ? 'https://www.sandbox.paypal.com/cgi-bin/webscr' : 'https://www.paypal.com/cgi-bin/webscr';

// Product being purchased.
$itemName = 'Test Item';
$itemAmount = 5.00;

// Include Functions
require 'functions.php';

// Check if paypal request or response
if (!isset($_POST["txn_id"]) && !isset($_POST["txn_type"])) {

    // Grab the post data so that we can set up the query string for PayPal.
    // Ideally we'd use a whitelist here to check nothing is being injected into
    // our post data.
    $data = [];
    foreach ($_POST as $key => $value) {
        $data[$key] = stripslashes($value);
    }

    // Set the PayPal account.
    $data['business'] = $paypalConfig['email'];

    // Set the PayPal return addresses.
    $data['return'] = stripslashes($paypalConfig['return_url']);
    $data['cancel_return'] = stripslashes($paypalConfig['cancel_url']);
    $data['notify_url'] = stripslashes($paypalConfig['notify_url']);

    // Set the details about the product being purchased, including the amount
    // and currency so that these aren't overridden by the form data.
    $data['item_name'] = $itemName;
    $data['amount'] = $itemAmount;
    $data['currency_code'] = 'GBP';

    // Add any custom fields for the query string.
    //$data['custom'] = USERID;

    // Build the query string from the data.
    $queryString = http_build_query($data);

    // Redirect to paypal IPN
    header('location:' . $paypalUrl . '?' . $queryString);
    exit();

} else {
    // Handle the PayPal response.
}
