传递给AwsAwsClient::getCommand()的参数2必须是array, string类型

我从这个页面开始安装。

是SDK的第3版。这里的基本用法

<?php
require 'vendor/autoload.php';
use Aws'CloudFront'CloudFrontClient;
$cdn = new CloudFrontClient(
['version' => 'latest',
 'region'  => 'us-east-1']
);
// Create a new invalidation.
$response = $cdn->create_invalidation('EPYAAAAAAPAA', 'aws-clear-cache' . time(), "/*");

根据本文

可捕获致命错误:参数2传递给Aws'AwsClient::getCommand()的类型必须是array, string given，在/Users/jason/www/aws/vendor/aws/aws-sdk-php/src/AwsClient.php上线167，定义为/Users/jason/www/aws/vendor/aws/aws-sdk-php/src/AwsClient.php上线211

更新,

$config = array(
                'region' => 'us-east-1',
                'version' => '2015-07-27',
                'credentials' => array(
                    'key'    => env('AMAZON_KEY_CLOUDFRONT'),  
                    'secret' => env('AMAZON_SECRET_CLOUDFRONT') 
                )
            );
        $cdn = new CloudFrontClient($config);
        $cache =    array('DistributionId' => env('CLOUDFRONT'),
                    'InvalidationBatch' => array(
                        'CallerReference' => 'none',
                        'Paths' => array(
                            'Quantity' => 1,
                            'Items' => array( 'test' => '/*')
                            )
                        )
            );
        // Create a new invalidation.
        $response = $cdn->createInvalidation($cache);
        var_dump($response);
