php - fatal error : Class 'Paypal\Api\Payer' not found en sdk Paypal

Question

我用 composer 安装了 PayPal SDK 但我的 php 文件 CHECKOUT.php 错误是:

Fatal error: Class 'Paypal\Api\Payer' not found in C:\xampp\htdocs\pagos\checkout.php on line 23

结帐.php:

<?php
require ("start.php");

use Paypal\Api\Payer;
use Paypal\Api\Item;

$payer = new Payer();
$payer->setPaymentMethod("paypal");

$item = new Item();
$item->setName($descripcion)
    ->setCurrency('MXN')
    ->setQuantity(1)
    ->setPrice($precio);
$itemList = new ItemList();
$itemList->setItems([$item]);

开始.php

<?php
// 1. Autoload the SDK Package. This will include all the files and classes to your autoloader
// Used for composer based installation
require __DIR__  . '/vendor/autoload.php';
// Use below for direct download installation
// require __DIR__  . '/PayPal-PHP-SDK/autoload.php';  

$apiContext = new \PayPal\Rest\ApiContext(
    new \PayPal\Auth\OAuthTokenCredential(
        'ashdjkhaskdjhalksdfjhaglskjdfhlasdfasdfsdfgh',     // ClientID
        'ejkhsdkjhakjdhakjshdkjashdkjashdkjaskjdhaskjh'      // ClientSecret
    )
);

$apiContext->setConfig([
 'mode'=>'sandbox',
 'http.ConnectionTimeOut'=>30,
 'log.LogEnabled'=>false,
 'log.FileName'=>'',
 'log.LogLevel'=>'FINE',
 'validation.level'=>'log'
]);

Answer 1

代替:
使用 Paypal\Api\Payer;
使用 Paypal\Api\Item;

将其更改为:
使用 PayPal\Api\Payer;
使用 PayPal\Api\Item;

只需将“PayPal”一词的第二个“P”大写即可。希望它有效:)
