Smart Payment Buttons 简称：spb支付话不多说 直接上demo1.首先申请好paypal收款账户；2.创建应用（分正式版live和沙盒环境）创建完成后 会生成 Client ID 和 Secret注意;这里是测试环境的参数 正式环境需要申请live html代码<!DOCTYPE html>

需要先引入PayPalCheckoutSdkhttps://github.com/paypal/Checkout-PHP-SDK创建订单代码：createOrder.php<?php
require __DIR__ . '/vendor/autoload.php';
//这个cofig.php 声明了2个全局变量 clientId 和 clientSecret
require __DIR__ . '/config.php';
use PayPalCheckoutSdk\Core\PayPalHttpClient;
use PayPalCheckoutSdk\Core\SandboxEnvironment;
use PayPalCheckoutSdk\Orders\OrdersCreateRequest;
$environment = new SandboxEnvironment($con['clientId'], $con['clientSecret']);
$client = new PayPalHttpClient($environment);
//获取支付金额
$money=$_POST['total_amt'];
$request = new OrdersCreateRequest();
$request->prefer('return=representation');
$request->body = [
"intent" => "CAPTURE",
"purchase_units" => [[
"reference_id" => "test_ref_id1",
"amount" => [
"value" => $money,
"currency_code" => "USD"
]
]],
"application_context" => [
"user_action"=> 'CONTINUE',
// 注意这里：NO_SHIPPING 代表是数字产品 无账单地址；
"shipping_preference"=> 'NO_SHIPPING',
"cancel_url" => "https://oiren.com/captureOrder.php", //回调地址
"return_url" => "https://oiren.com/captureOrder.php"
]
];
try {
$response = $client->execute($request);
$res=array(
'ack'=>true,
'data'=>array("id"=>$response->result->id)
);
echo json_encode($res);
exit;
}catch (HttpException $ex) {
echo $ex->statusCode;
print_r($ex->getMessage());
} 捕获订单：captureOrder.php<?php
require __DIR__ . '/vendor/autoload.php';
require __DIR__ . '/config.php';
use PayPalCheckoutSdk\Core\PayPalHttpClient;
use PayPalCheckoutSdk\Core\SandboxEnvironment;
use PayPalCheckoutSdk\Orders\OrdersCaptureRequest;
$environment = new SandboxEnvironment($con['clientId'], $con['clientSecret']);
$client = new PayPalHttpClient($environment);
$content=file_get_contents("php://input");
$json=json_decode($content,true);
$orderID=$json['orderID'];
file_put_contents("1.txt",$orderID.PHP_EOL,FILE_APPEND);
$request = new OrdersCaptureRequest($orderID);
$request->prefer('return=representation');
try {
// Call API with your client and get a response for your call
$response = $client->execute($request);
if(empty($response)){
$response = $client->execute($request);
}
if($response->statusCode == 201){
$aa['msg'] = 'COMPLETED';
}else{
$aa['msg'] == 'error';
}
// If call returns body in response, you can get the deserialized version from the result attribute of the response
echo json_encode($aa);
exit;
//验证通过获取到订单的详细信息可以写入到数据库
}catch (HttpException $ex) {
echo $ex->statusCode;
var_dump($ex->getMessage());
}
到这里支付流程就跑完了，测试的时候可以先用palpay的测试账户 进行测试；ps:测试环境请求的api接口不同，需修改api路径；/vendor/paypal/paypal-checkout-sdk/lib/PayPalCheckoutSdk/Core/SandboxEnvironment.php换到正式环境 不要忘记切换请求地址；有问题可以给我留言；
