如果没有发生错误，如何使Try/catch条错误处理程序将用户发送到success.php？

Question

我正在为我的业务建立一个结账页面，我正在为此使用Stripe。当错误处理程序没有返回错误时，我的charge.php文件出现了问题，不能重定向。

我尝试使用header()函数，如果输入正确的卡片详细信息，就可以成功地重定向，但是当我尝试使用用于显示错误消息的卡片之一时，它只是重定向到输入表单所在的index.html。如果删除标头函数，charge.php将成功地显示错误，但显然，成功的充电不会出现重定向。

  // added stripe dependencies with composer
require_once('vendor/autoload.php');

  \Stripe\Stripe::setApiKey('SECRETKEY');

 // Sanitize POST Array
 $POST = filter_var_array($_POST, FILTER_SANITIZE_STRING);

 $first_name = $POST['first_name'];
 $last_name = $POST['last_name'];
 $email = $POST['email'];
 $token = $POST['stripeToken'];

// Create Customer In Stripe
try {
$customer = \Stripe\Customer::create(array(
  "email" => $email,
  "source" => $token
));

// Charge Customer

$charge = \Stripe\Charge::create(array(
  "amount" => 4999,
  "currency" => "usd",
  "description" => "Online Purchase",
  "customer" => $customer->id
));

//ERROR HANDLER
} catch ( Stripe\Error\Base $e ) {
  // Code to do something with the $e exception object when an error occurs.
  echo $e->getMessage();

  // DEBUG.
  $body = $e->getJsonBody();
  $err  = $body['error'];
  echo '<br> ——— <br>';
  echo '<br>YOU HAVE NOT BEEN CHARGED — <br>';
  echo '— Status is: ' . $e->getHttpStatus() . '<br>';
  echo '— Message is: ' . $err['message'] . '<br>';
  echo '— Type is: ' . $err['type'] . '<br>';
  echo '— Param is: ' . $err['param'] . '<br>';
  echo '— Code is: ' . $err['code'] . '<br>';
  echo '<p>If you have entered the correct details, please try DOMAIN (in Safari or Chrome). If the error persists, please screenshot this message and send it to me alongside your email address.</p>';
  echo '<br> ——— <br>';

// Catch any other non-Stripe exceptions.
} catch ( Exception $e ) {
    $body = $e->getJsonBody();
    $err  = $body['error'];
    echo '<br> ——— <br>';
    echo '<br>Error — <br>';
    echo '— Status is: ' . $e->getHttpStatus() . '<br>';
    echo '— Message is: ' . $err['message'] . '<br>';
    echo '— Type is: ' . $err['type'] . '<br>';
    echo '— Param is: ' . $err['param'] . '<br>';
    echo '— Code is: ' . $err['code'] . '<br>';
    echo '<p>If you have entered the correct details, please try DOMAIN (in Safari or Chrome). If the error persists, please screenshot this message and send it to me alongside your email address.</p>'; 
    echo '<br> ——— <br>';
}

header('Location: success.php?tid='.$charge->id.'&product='.$charge->description);

我期望charge.php在成功充电时重定向到success.php，并在错误电荷上显示错误。

Answer 1

它执行重定向，因为它是在catch块之后。这些块将被执行，并且因为其中没有return语句，所以它将继续执行在块之后的下一行--您的重定向头行。

你可以：

1. 将header(....)行移动到您的try块中，就在电荷创建之后
2. 在您的return块中执行特定的exit或exit类型的行。

两者都是可行的解决办法。
