Question

我创建了一个使用Stripe和PayPal的应用。为了获取令牌，我使用XAMPP在Mac上创建了一个本地后端服务器。

//。。。通过发出HTTP POST请求将令牌发送到我们的后端

func postStripeToken(token: STPToken) {

    let URL = "http://localhost/ryde/payment.php"
    let params = ["stripeToken": token.tokenId,
                  "amount": Double(self.driverInfoView.rydeFare.text!)!,
                  "currency": "cad",
                  "description": self.riderName] as [String : Any]

    let manager = AFHTTPSessionManager()
    manager.post(URL, parameters: params, success: { (operation, responseObject) -> Void in

        if let response = responseObject as? [String: String] {

            let alertController = UIAlertController(title: response["status"], message: response["message"], preferredStyle: .alert)

            let defaultAction = UIAlertAction(title: "OK", style: .default, handler: nil)
            alertController.addAction(defaultAction)

            self.present(alertController, animated: true, completion: nil)
        }

    }) { (operation, error) -> Void in
        self.handleError(error as NSError)
        print(error)
    }
}

payment.php

<?php
require_once('vendor/autoload.php');

// Set your secret key: remember to change this to your live secret key  in production
// See your keys here https://dashboard.stripe.com/account/apikeys
\Stripe\Stripe::setApiKey("sk_test_**********************");

// Get the credit card details submitted by the form
$token =  $_POST['stripeToken'];
$amount = $_POST['amount'];
$currency = $_POST['currency'];
// $description = $_POST['description'];

// Create the charge on Stripe's servers - this will charge the user's   card
try {
$charge = \Stripe\Charge::create(array(
"amount" => $amount*100, // Convert amount in cents to dollar
"currency" => $currency,
"source" => $token,
// "description" => $description)
);

// Check that it was paid:
if ($charge->paid == true) {
    $response = array( 'status'=> 'Success', 'message'=>'Payment has been charged!!' );
} else { // Charge was not paid!
    $response = array( 'status'=> 'Failure', 'message'=>'Your payment could NOT be processed because the payment system rejected the transaction. You can try again or use another card.' );
}
header('Content-Type: application/json');
echo json_encode($response);

} catch(\Stripe\Error\Card $e) {
// The card has been declined
}

?>

问题是，如果我使用本地服务器，我必须始终运行XAMPP，以便移动应用程序中没有打嗝。

如何创建外部后端而不是本地后端？

您需要做的就是

1）启动在Ubuntu上运行的linux实例服务器。您可以使用AWS或heroku

2）通过命令行

在其上安装XAMPP

wget http://sourceforge.net/projects/xampp/files/XAMPP%20Linux/1.8.3/xampp-linux-x64-1.8.3-5-installer.run

3）使其可执行

sudo chmod +x xampp-linux-x64-1.8.3-5-installer.run

4）运行安装

sudo ./xampp-linux-x64-1.8.3-5-installer.run

5）启动Xampp。这将使Xampp启动并运行。

sudo /opt/lampp/lampp start

5）将PHP代码文件夹复制到/opt/lampp/htdocs

6）运行以下命令重新启动XAMPP

sudo /opt/lampp/lampp restart

7）最后将swift代码中的URL从localhost更改为远程服务器URL

let URL = "Your server URL/payment.php"

这就是你需要做的一切。
