如何在yii2中使用paypal扩展。我正在使用此链接
https://github.com/marciocamello/yii2-paypal 。
我安装了扩展程序，并在配置文件中添加了代码。
但是没有更多信息下一步该做什么。所以请帮助我。

无需为此使用扩展名。您只需安装paypal/rest-api-sdk-php包并执行以下步骤即可。
在components目录中创建@app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，此文件夹位于您要启用付款的应用中。
使用以下内容创建一个PHP类文件（例如CashMoney）
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 $this->apiContext;
}
}
这足以开始使用。您可以选择稍后添加特定于PayPal的其他配置。
在app/config/main.php（或app/config/main-local.php）中，添加以下内容以注册CashMoney组件。
'components' => [
...
'cm' => [ // bad abbreviation of "CashMoney"; not sustainable long-term
'class' => 'app/components/CashMoney', // note: this has to correspond with the newly created folder, else you'd get a ReflectionError
// Next up, we set the public parameters of the class
'client_id' => 'YOUR-CLIENT-ID-FROM-PAYPAL',
'client_secret' => 'YOUR-CLIENT-SECRET-FROM-PAYPAL',
// You may choose to include other configuration options from PayPal
// as they have specified in the documentation
],
...
]
现在我们的付款组件已注册为CashMoney，我们可以使用Yii::$app->cm访问它。很酷，嗯？
Yii2中的Make Your First API call，
打开要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;
}
...
}
...
}
预期输出类似于PayPal文档中的输出。
一旦建立连接，您应该能够执行其他任务。

这是我的解决方案，它适用于yii2高级tempalte！
我将此类marciocamello / yii2-paypal / PayPal.php从供应商文件夹移至common / component / PayPal.php
你必须＆＃34;包括＆＃34;组件部分下的frontend \ config \ main.php中的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，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;
}
在站点控制器中，我称之为组件功能
echo '<pre/>';
print_r(Yii::$app->paypal->payDemo());
exit();
我通过重定向网址，transactionId等获得了成功的回复。
-------------- 400 ERROR Debuging ----------
我总是得到400错误，因为我有价格格式的问题，我使用number_format函数修复它。
我修改了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);
如果仍然出现400或40x错误，您可以在第107行的PPHttpConnection.php中打印整个PayPal响应和错误消息等。
$ex->setData($result);
// echo '<pre>';
// print_r($ex);exit;
throw $ex;

https://github.com/marciocamello/yii2-paypal。通过此扩展，您可以设置/安装此链接上可用的paypal库 -
https://github.com/paypal/PayPal-PHP-SDK
这个papypal-php-SDK有不同方法的例子。
我已在YII2中安装/设置此库并使用了付款方式。

我在我的网站上使用基于Rest API的paypal express checkout。无需任何第三方扩展。该解决方案可以应用于任何网站，通常不限于Yii框架。要获得基本概念，请阅读https://developer.paypal.com/docs/integration/direct/express-checkout/integration-jsv4/
这是我的方法：
在https://developer.paypal.com中创建REST API APP。创建APP后，您将获得客户端ID和密钥，以便稍后用于身份验证。
在您要显示结帐按钮的网页上，创建一个空div
<div id="paypal-button"></div>
在您的资源中加入https://www.paypalobjects.com/api/checkout.js个javascript。
4.使用以下Javascript代码恢复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');
现在您需要对创建付款进行编码并在控制器中执行付款方式。
/* 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);
}
最后创建一个组件来进行身份验证/生成令牌并执行付款。
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",

);
$postData = array(

);
$curlPostData = http_build_query($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(

foreach ($curlResponse['json']['links'] as $link) {
if($link['rel'] == 'approval_url'){
$approval_url = $link['href'];
}
}
}
$res = ['paymentID' =>$id,'approval_url'=>$approval_url];
return $res;
}
public function executePayment() {
$curlUrl = $this->url."/v1/payments/payment/".$this->paymentID."/execute";
$curlHeader = array(
"Content-Type:application/json",
"Authorization:Bearer ".$this->access_token,
);
$postData = array(
"payer_id" => $this->payerID
);
$curlPostData = json_encode($postData);
$curlResponse = $this->curlCall($curlUrl, $curlHeader, $curlPostData);
return $curlResponse;
}
function curlCall($curlServiceUrl, $curlHeader, $curlPostData) {
// response container
$resp = array(
"http_code" => 0,
"json" => ""
);
//set the cURL parameters
$ch = curl_init($curlServiceUrl);
curl_setopt($ch, CURLOPT_VERBOSE, 1);
//turning off the server and peer verification(TrustManager Concept).
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
curl_setopt($ch, CURLOPT_SSLVERSION , 'CURL_SSLVERSION_TLSv1_2');
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
//curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $curlHeader);
if(!is_null($curlPostData)) {
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $curlPostData);
}
//getting response from server
$response = curl_exec($ch);
$http_code = curl_getinfo($ch, CURLINFO_HTTP_CODE);
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;
}
}
