以创建一个Standard的计划为例，其参数如下：
$param = [
"name" => "standard_monthly",
"display_name" => "Standard Plan",
"desc" => "standard Plan for one month",
"type" => "REGULAR",
"frequency" => "MONTH",
"frequency_interval" => 1,
"cycles" => 0,
"amount" => 20,
"currency" => "USD"
];
创建并激活计划代码如下：
//上面的$param例子是个数组，我的实际应用传入的实际是个对象，用户理解下就好。
public function createPlan($param)
{
$apiContext = $this->getApiContext();
$plan = new Plan();
// # Basic Information
// Fill up the basic information that is required for the plan
$plan->setName($param->name)
->setDescription($param->desc)
->setType('INFINITE');//例子总是设置为无限循环
// # Payment definitions for this billing plan.
$paymentDefinition = new PaymentDefinition();
// The possible values for such setters are mentioned in the setter method documentation.
// Just open the class file. e.g. lib/PayPal/Api/PaymentDefinition.php and look for setFrequency method.
// You should be able to see the acceptable values in the comments.
$paymentDefinition->setName($param->name)
->setType($param->type)
->setFrequency($param->frequency)
->setFrequencyInterval((string)$param->frequency_interval)
->setCycles((string)$param->cycles)
->setAmount(new Currency(array('value' => $param->amount, 'currency' => $param->currency)));
// Charge Models
$chargeModel = new ChargeModel();
$chargeModel->setType('TAX')
->setAmount(new Currency(array('value' => 0, 'currency' => $param->currency)));
$returnUrl = config('payment.returnurl');
$merchantPreferences = new MerchantPreferences();
$merchantPreferences->setReturnUrl("$returnUrl?success=true")
->setCancelUrl("$returnUrl?success=false")
->setAutoBillAmount("yes")
->setInitialFailAmountAction("CONTINUE")
->setMaxFailAttempts("0")
->setSetupFee(new Currency(array('value' => $param->amount, 'currency' => 'USD')));
$plan->setPaymentDefinitions(array($paymentDefinition));
$plan->setMerchantPreferences($merchantPreferences);
// For Sample Purposes Only.
$request = clone $plan;
// ### Create Plan
try {
$output = $plan->create($apiContext);
} catch (Exception $ex) {
return false;
}
$patch = new Patch();
$value = new PayPalModel('{"state":"ACTIVE"}');
$patch->setOp('replace')
->setPath('/')
->setValue($value);
$patchRequest = new PatchRequest();
$patchRequest->addPatch($patch);
$output->update($patchRequest, $apiContext);
return $output;
} 2.创建订阅(创建Agreement)，然后将跳转到Paypal的网站等待用户同意
Plan创建后，要怎么让用户订阅呢，其实就是创建Agreement,关于Agreement，有以下注意点：
例子参数如下：
$param = [
'id' => 'P-26T36113JT475352643KGIHY',//上一步创建Plan时生成的ID
'name' => 'Standard',
'desc' => 'Standard Plan for one month'
];
代码如下：
public function createPayment($param)
{
$apiContext = $this->getApiContext();
$agreement = new Agreement();
$agreement->setName($param['name'])
->setDescription($param['desc'])
->setStartDate(Carbon::now()->addMonths(1)->toIso8601String());
// Add Plan ID
// Please note that the plan Id should be only set in this case.
$plan = new Plan();
$plan->setId($param['id']);
$agreement->setPlan($plan);
// Add Payer
$payer = new Payer();
$payer->setPaymentMethod('paypal');
$agreement->setPayer($payer);
// For Sample Purposes Only.
$request = clone $agreement;
// ### Create Agreement
try {
// Please note that as the agreement has not yet activated, we wont be receiving the ID just yet.
$agreement = $agreement->create($apiContext);
// ### Get redirect url
// The API response provides the url that you must redirect
// the buyer to. Retrieve the url from the $agreement->getApprovalLink()
// method
$approvalUrl = $agreement->getApprovalLink();
} catch (Exception $ex) {
return "create payment failed, please retry or contact the merchant.";
}
return $approvalUrl;//跳转到$approvalUrl，等待用户同意
}
函数执行后返回$approvalUrl，记得通过redirect($approvalUrl)跳转到Paypal的网站等待用户支付。 用户同意后，执行订阅
用户同意后，订阅还未完成，必须执行Agreement的execute方法才算完成真正的订阅。这一步的注意点在于
完成订阅后，并不等于扣款，可能会延迟几分钟；
如果第一步的setSetupFee费用设置为0，则必须等到循环扣款的时间到了才会产生订单；
代码片段如下：
public function onPay($request)
{
$apiContext = $this->getApiContext();
if ($request->has('success') && $request->success == 'true') {
$token = $request->token;
$agreement = new \PayPal\Api\Agreement();
try {
$agreement->execute($token, $apiContext);
} catch(\Exception $e) {
return ull;
return $agreement;
}
return null;
} 获取交易记录
订阅后，可能不会立刻产生交易扣费的交易记录，如果为空则过几分钟再次尝试。本步骤注意点：
