Paypal-jfinal

This is a very simple demo[SDK] for PayPal with Credit Card Payment Only.
[jFinal is a light, powerful Java framework]

How to setup?

1. Get a PayPal Account 2. Create an App in https://developer.paypal.com/, then you can get `REST API CREDENTIALS`  3. Update [`sdk_config.properties`](src/main/resources/sdk_config.properties)

Support Credit Card Types

must be visa, mastercard, amex, or discover

Unit Test

I provide a usage demo in [Unit test](src/main/java/me/hzhou/paypal/test/UnitTest.java) ``` @Test public void paymentTest() { PayPal paypal = new PayPal(); paypal.setBillAddress("52 N Main ST", "Johnstown", "US", "OH", "43210");

	// Never mind, this is a fake information from PayPal Developer Center
	// sorry
	paypal.setCreditCard("4417119669820331", "visa", 11, 2018, "874", "Joe", "Shopper");
	
	// 1.50 doesn't include tax
	paypal.setAmount(1.50);
	
	// output details as
	/*{
	  "shipping": "0",
	  "subtotal": "1.50",
	  "tax": "0.09"
	}
	*/
	System.out.println(paypal.getDetails().toJSON());
	
	Payment payment = paypal.pay();
	System.out.println(payment.toJSON());
	
}
