Question

如何在yii2中使用paypal扩展。我正在使用此链接
https://github.com/marciocamello/yii2-paypal。
我安装了扩展并在配置文件中添加了代码。

但没有更多信息下一步该做什么。所以请帮助我。

谢谢

Answer 1

我在我的网站中使用基于 Rest API 的 paypal express checkout。无需任何第三方扩展。该解决方案一般适用于任何网站，不限于 Yii 框架。要了解基本概念，请阅读https://developer.paypal.com/docs/integration/direct/express-checkout/integration-jsv4/

这是我的方法：

1. 在 https://developer.paypal.com 中创建一个 REST API 应用程序。一旦你创建了你的APP，你就会得到Client ID和Secret Key，供以后进行身份验证使用。

2. 在您要显示结帐按钮的网页上，创建一个空 div <div id="paypal-button"></div>

3. 在您的资产中包含 https://www.paypalobjects.com/api/checkout.js javascript。

4.使用以下Javascript代码渲染paypal按钮

paypal.Button.render({
    env: 'sandbox', // Specify 'sandbox' for the test environment
    client: {
        sandbox: 'CLIENT-ID of your APP in step1'           
    },
    payment: function (resolve, reject) {

        /* URL which would create payment */
        var CREATE_PAYMENT_URL = '/transactions/create-paypal';

        paypal.request.post(CREATE_PAYMENT_URL)
            .then(function (data) {
                resolve(data.paymentID);
            })
            .catch(function (err) {
                reject(err);
            });
    },

    onAuthorize: function (data, actions) {

        // Execute the payment here, when the buyer authorize and approves the transaction
        var EXECUTE_PAYMENT_URL = '/transactions/execute-paypal';
        paypal.request.post(EXECUTE_PAYMENT_URL,
            {paymentID: data.paymentID, payerID: data.payerID, token: data.paymentToken,serviceId:serviceId})

            .then(function (data) {
                console.log(data);
                if(data.http_code == '200') {
                    /* payment done .. do something here */
                    handleCreateService(url);
                }else {
                    /* something didn't went right with payment */
                }
            })
            .catch(function (err) {
                /* catch any exceptions */
                console.log(err);
            });
    }

}, '#paypal-button');

5. 现在您需要在控制器中编写创建付款并执行付款方式的代码。

   /* Create Paypal function will pass token,
   paymentID back to JS in step 4. */
   
   public function actionCreatePaypal() {        
       $paypal = new Paypal();
       $paypal->getToken();
       $res = $paypal->createPayment();
       echo json_encode($res);
   }
   
   public function actionExecutePaypal() {
       $paymentID = $_POST['paymentID'];
       $payerID =  $_POST['payerID'];
       $access_token = $_POST['token'];
       $paypal = new Paypal(['paymentID'=>$paymentID,'payerID' =>$payerID,'access_token' =>$access_token]);
       $paypal->getToken();
       $res = $paypal->executePayment();
       echo json_encode($res);
   }    
   

6. 最后创建一个组件来进行身份验证/生成令牌并执行支付。

   class Paypal {  
   
       public $url;
       public $env;
       public $clientId;
       public $clientSecret;
       public $access_token;
       public $paymentID;
       public $payerID;
       public $premiumService;
   
       public function __construct($params=0) {
           $this->access_token = '';
           /* for sandbox url is https://api.sandbox.paypal.com */
           $this->url = \Yii::$app->params['paypal_url'];
           $this->clientId = \Yii::$app->params['paypal_clientId'];
           $this->clientSecret = \Yii::$app->params['paypal_clientSecret'];
   
           if(isset($params['paymentID'])) {
               $this->paymentID = $params['paymentID'];
           }
   
           if(isset($params['payerID'])) {
               $this->payerID = $params['payerID'];
           }
   
           if(isset($params['access_token'])) {
               $this->access_token = $params['access_token'];
           }
   
           /* This is where you describe the product you are selling */    
           $this->premiumService = '{
           "intent":"sale",
           "redirect_urls":{
                "cancel_url":"https://cancelurl.com",
                "return_url":"https://returnurl.com"
           },
           "payer":{
               "payment_method":"paypal"
           },
           "transactions":[
           {
               "amount":{
               "currency":"USD",
               "total":"39.00"
               },
               "item_list":{
                   "items": [
                   {
                       "quantity": "1",
                       "name": "Premium Service",
                       "price": "39.00",
                       "currency": "USD",
                       "description": "Purchase allows one time use of this premium service"
                   }]
               },
               "description":"Premium Service"
   
           }]
           }';
   }
   public function getToken() {
       $curlUrl = $this->url."/v1/oauth2/token";
       $curlHeader = array(
           "Content-type" => "application/json",
           "Authorization: Basic ". base64_encode( $this->clientId .":". $this->clientSecret),
       );

       );
   
       $curlPostData = http_build_query($postData);
       $curlResponse = $this->curlCall($curlUrl, $curlHeader, $curlPostData);
       if($curlResponse['http_code'] == 200) {
           $this->access_token = $curlResponse['json']['access_token'];
       }
   }
   
   
   public function createPayment() {
       $curlUrl = $this->url."/v1/payments/payment";
       $curlHeader = array(
           "Content-Type:application/json",
           "Authorization:Bearer  ". $this->access_token,
       );
   
   
       $curlResponse = $this->curlCall($curlUrl, $curlHeader, $this->premiumService);
       $id = null;
       $approval_url = null;
       if($curlResponse['http_code'] == 201) {
           $id = $curlResponse['json']['id'];
           foreach ($curlResponse['json']['links'] as $link) {
               if($link['rel'] == 'approval_url'){
                   $approval_url = $link['href'];
               }
           }
       }
   
       $res = ['paymentID' =>$id,'approval_url'=>$approval_url];
       return $res;

       );
   
       $curlPostData = json_encode($postData);

       );
   
       //set the cURL parameters
       $ch = curl_init($curlServiceUrl);

       curl_close($ch); // close cURL handler
   
       // some kind of an error happened
       if (empty($response)) {
           return $resp;
       }
   
       $resp["http_code"] = $http_code;
       $resp["json"] = json_decode($response, true);
   
       return $resp;
   
   }
   }
   

Answer 2

无需为此使用扩展程序。您可以简单地安装paypal/rest-api-sdk-php 包并执行以下步骤。

1。创建一个组件将 Paypal 粘合到 Yii2

在您的@app 目录中创建一个components 文件夹。如果您使用的是基本模板，则这是与webroot 相同的文件夹；在高级模板中，此文件夹位于您要启用付款的应用中。

创建一个PHP类文件（例如CashMoney），内容如下

use yii\base\Component;

use PayPal\Rest\ApiContext;
use PayPal\Auth\OAuthTokenCredential;

class CashMoney extends Component {
  public $client_id;
  public $client_secret;
  private $apiContext; // paypal's API context

  // override Yii's object init()
  function init() { 
    $this->apiContext = new ApiContext(
      new OAuthTokenCredential($this->client_id, $this->client_secret)
    );
  }

  public function getContext() {
    return $this->apiContext;
  }
}

这足以开始。稍后您可以选择添加特定于 PayPal 的其他配置。

2。用 Yii2 注册你的胶水组件

在您的app/config/main.php（或app/config/main-local.php）中，包含以下内容以注册CashMoney 组件。

'components' => [
  ...
  'cm' => [ // bad abbreviation of "CashMoney"; not sustainable long-term
    'class' => 'app/components/CashMoney', // note: this has to correspond with the newly created folder, else you'd get a ReflectionError

     // Next up, we set the public parameters of the class
    'client_id' => 'YOUR-CLIENT-ID-FROM-PAYPAL',
    'client_secret' => 'YOUR-CLIENT-SECRET-FROM-PAYPAL',
    // You may choose to include other configuration options from PayPal
    // as they have specified in the documentation
  ],
  ...
]

现在我们的支付组件注册为CashMoney，我们可以使用Yii::$app->cm 访问它。很酷吧？

3。进行 API 调用

致 Yii2 中的Make Your First API call，

打开您要在其中处理付款的控制器操作，并包括以下内容

use Yii;
...
use PayPal\Api\CreditCard;
use PayPal\Exception\PaypalConnectionException;

class PaymentsController { // or whatever yours is called
  ...
  public function actionMakePayments { // or whatever yours is called
    ...
    $card = new PayPalCreditCard;
    $card->setType('visa')
      ->setNumber('4111111111111111')
      ->setExpireMonth('06')
      ->setExpireYear('2018')
      ->setCvv2('782')
      ->setFirstName('Richie')
      ->setLastName('Richardson');

    try {
      $card->create(Yii::$app->cm->getContext());
      // ...and for debugging purposes
      echo '<pre>';
      var_dump('Success scenario');
      echo $card;
    } catch (PayPalConnectionException) {
      echo '<pre>';
      var_dump('Failure scenario');
      echo $e;
    }
    ...
  }

  ...

}

预期的输出类似于 PayPal 文档中的输出。

连接成功后，您应该能够执行其他任务。

Answer 3

https://github.com/marciocamello/yii2-paypal。通过此扩展，您只需设置/安装可在此链接上使用的贝宝库- https://github.com/paypal/PayPal-PHP-SDK
这个 papypal-php-SDK 有不同方法的例子。

我已经在 YII2 中安装/设置了这个库并使用了支付方式。

Answer 4

这是我的解决方案，它适用于 yii2 高级模板！

我已将此类 marciocamello/yii2-paypal/PayPal.php 从供应商文件夹移至 common/component/PayPal.php

您必须在组件部分下的 frontend\config\main.php 中“包含”common\components\paypal：

 'components' => [
    'paypal'=> [
        'class'        => 'common\components\Paypal',
        'clientId'     => 'your id you can find it over your paypal develpoer account. Ypu ah to create an application',
        'clientSecret' => 'your id you can find it over your paypal develpoer account. Ypu ah to create an application',
        'isProduction' => false,
         // This is config file for the PayPal system
         'config'       => [
             'http.ConnectionTimeOut' => 30,
             'http.Retry'             => 1,
             'mode'                   => \common\components\Paypal::MODE_SANDBOX, 
             'log.LogEnabled'         => YII_DEBUG ? 1 : 0,
             'log.FileName'           => '@runtime/logs/paypal.log',
             'log.LogLevel'           => \common\components\Paypal::LOG_LEVEL_INFO,
        ]
    ],

],

在第 11 行的 PPHttpConfig.php 中，我更改了以下行

    //CURLOPT_SSLVERSION => 3,
    CURLOPT_SSLVERSION => 'CURL_SSLVERSION_TLSv1',

在第 48-52 行的 PPLoggingManager.php 中，我对日志路径进行了硬编码

if($this->isLoggingEnabled) {
        $this->loggerFile = $_SERVER['DOCUMENT_ROOT'].'/domain/frontend/runtime/logs/paypal.log';//($config['log.FileName']) ? $config['log.FileName'] : ini_get('error_log');
        $loggingLevel = strtoupper($config['log.LogLevel']);
        $this->loggingLevel = (isset($loggingLevel) && defined(__NAMESPACE__."\\PPLoggingLevel::$loggingLevel")) ? constant(__NAMESPACE__."\\PPLoggingLevel::$loggingLevel") : PPLoggingManager::DEFAULT_LOGGING_LEVEL;
    }

在站点控制器中，我调用了组件函数

      echo '<pre/>';
  print_r(Yii::$app->paypal->payDemo());  
  exit();

我收到了带有重定向 url、transactionId 等的成功响应。

--------------  400 ERROR Debuging ----------

我总是收到 400 错误，因为我的价格格式有问题，我使用 number_format 函数修复了它。

我稍微修改了 payDemo() 函数。

    $amount = 16;    
$formattedAmount = number_format($amount,2);
        $payer = new Payer();
        $payer->setPayment_method("paypal");
        $item1 = new Item();
$item1->setName('Ground Coffee 40 oz')
    ->setCurrency('USD')
    ->setQuantity(1)
    ->setPrice($formattedAmount);
$item2 = new Item();
$item2->setName('Granola bars')
    ->setCurrency('USD')
    ->setQuantity(1)
    ->setPrice($formattedAmount);
$itemList = new ItemList();

$itemList->setItems(array($item1, $item2));
        //  $amountDetails = new Details();
        // $amountDetails->setSubtotal('7');
        // $amountDetails->setTax('0.00');
        // $amountDetails->setShipping('0.00');

         $amount = new Amount();
        $amount->setCurrency('USD');
        $amount->setTotal(number_format((2*$formattedAmount),2));
      //  $amount->setDetails($amountDetails);

        $transaction = new Transaction();
        $transaction->setDescription("creating a payment");
        $transaction->setItemList($itemList);
        $transaction->setAmount($amount);

        //$baseUrl = getBaseUrl();
        $redirectUrls = new RedirectUrls();
        $redirectUrls->setReturn_url("https://devtools-paypal.com/guide/pay_paypal/php?success=true");
        $redirectUrls->setCancel_url("https://devtools-paypal.com/guide/pay_paypal/php?cancel=true");

        $payment = new Payment();
        $payment->setIntent("sale");
        $payment->setPayer($payer);
        $payment->setRedirect_urls($redirectUrls);
        $payment->setTransactions(array($transaction));


        return $payment->create($this->_apiContext);

如果您仍然收到 400 或 40x 错误，您可以在第 107 行的 PPHttpConnection.php 中打印带有错误消息等的整个 PayPal 响应。

    $ex->setData($result);
        // echo '<pre>';
        // print_r($ex);exit;
        throw $ex;
