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。

但是没有更多的信息告诉我接下来该怎么做。请帮助我。

谢谢

也许最好向实际的开发人员询问。您可以在Github上创建问题，以解决文档中的问题。从我所看到的情况来看，文档相当差，也没有其他链接可以提供。另一个选择是通过查看源代码自己找出答案。除了init和demo之外，主类中只有一个方法和配置文件。也许扩展处于开发的初期阶段。 - arogachev

不是答案，只是想知道http://paypal.github.io/PayPal-PHP-SDK/是否有所帮助。我不是YII开发人员，因此不确定它是否需要特别考虑。PayPal-PHP-SDK在composer中可用作`paypal/rest-api-sdk-php`。 - Jay Patel - PayPal

这是我的解决方案，它可以与yii2高级模板一起使用！

我将marciocamello/yii2-paypal/PayPal.php类从vendor文件夹移动到common/component/PayPal.php。

您需要在frontend\config\main.php的components部分中“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PPHttpConfig.php文件的第11行，我已经更改了以下行：

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

在PPLoggingManager.php的48-52行，我已经硬编码了日志路径。

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;
    }

在网站控制器中，我调用了组件函数。

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

我收到了一个成功的响应，其中包括重定向URL、交易ID等信息。

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

我一直遇到400错误，因为价格格式有问题，我使用number_format函数进行了修复。

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，可以在PPHttpConnection.php的107行打印整个PayPal响应与错误消息等内容。

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

你好，能否提供您的电子邮件地址？我有一个使用PayPal模块的YII2高级入门项目，并且它运行良好。我可以通过电子邮件将其发送给您。 :) - Nagy Ervin

我刚刚发送了一封电子邮件：)。如果您有任何问题，请随时与我联系。 - Nagy Ervin

请检查您的收件箱。我已经发送了一个链接，您可以通过它下载项目。祝您有愉快的一天。 - Nagy Ervin

感谢nagy的回复，按照您的建议，它起作用了。我的问题是这样的。 1）当我们加入任何项目时，以https://www.elegantthemes.com/join.php为例，有三种类型的订阅。这就像订阅一样。在订阅期结束后，我将自动支付预付款，例如一个月或一年。这是PayPal的循环付款，我如何在yii2中实现这一点。谢谢 - jatin vaghasiya

不需要将类移出供应商位置。只需从composer包含自动加载程序，并在Yii 2控制器类的顶部使用路径/到/类;以访问库类的逻辑。 - David J Eddy

我在我的网站上使用基于Rest API的Paypal Express Checkout。不需要任何第三方扩展。该解决方案通常适用于任何网站，而不仅限于Yii框架。要了解基本概念，请阅读https://developer.paypal.com/docs/integration/direct/express-checkout/integration-jsv4/。

以下是我的方法：

在https://developer.paypal.com中创建一个REST API APP。创建APP后，您将获得客户端ID和密钥，稍后用于身份验证。
在您希望显示结帐按钮的网页上，创建一个空div <div id="paypal-button"></div>
在您的资源中包含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');

Now you need to code your create payment and execute payment methods in controller.

/* 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);
}

Finally create a component to do authentication/ generating token and executing payment.

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(

不需要使用扩展程序。您可以简单地安装paypal/rest-api-sdk-php软件包并执行以下步骤。

1. 创建一个组件将Paypal连接到Yii2

在@app目录中创建一个components文件夹。如果您使用的是基本模板，则该文件夹与webroot相同；在高级模板中，此文件夹位于要启用支付的应用程序中。

创建一个名为PHP类文件（例如CashMoney）且具有以下内容：

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;
  }
}

这已经足够开始了。您可以选择稍后添加其他针对PayPal的配置。

2. 在Yii2中注册您的“粘合”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
  ],
  ...
]

现在我们已经将付款组件注册为CashMoney，我们可以使用Yii::$app->cm进行访问。很酷，是吧？

3. 进行API调用

要在Yii2中进行第一次API调用，

打开你想处理付款的控制器操作，并包含以下内容：

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;
    }
    ...
  }

  ...

}

预期输出的格式与 PayPal 文档类似。

一旦连接成功，您应该能够执行其他任务。
