当我单击贝宝（PayPal）集成按钮时，它会显示此错误，该错误也在我的幼虫5.7标题中写了
下面是我的控制器代码

这是我在控制器中使用的代码，其中的重定向代码使我无法理解
这是我的路线，我在这段代码中出错的地方找不到错误
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');

首先，我将向您展示如何使用自定义php集成贝宝。
1）这是Paypal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="customer@example.com" />
<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，以及处理付款后的传入响应。
// 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' => 'user@example.com',
'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.
}
答案 1 :(得分：-1)
错误消息非常清楚，check the documentation on redirects。调用重定向方法时，您将收到一个RedirectResponse实例。检查您的代码并查找对redirect或back的调用，并根据错误消息跟踪您对返回的数据的处理方式，我可以从错误消息中猜测您是显式的还是隐式的（调用具有string类型的提示参数）对该值执行string转换，正如您可以从错误中看到的那样，该转换不能自动完成。
这就是我看不到您的代码的全部内容。
