Laravel 拉威尔aws空白页

我已经在本地公司安装了laravel+laravel aws软件包，一切正常。然后我通过ftp将所有代码移动到我的主机提供商，aws停止工作

我的代码

Route::get('/', function()
{
    error_reporting(E_ALL); ini_set('display_errors', '1');
    $db = AWS::get('DynamoDb');
    $result = $db->listTables();
    print_r($result);
    return;
});

在我的comp it输出上

Guzzle\Service\Resource\Model对象（[structure:protected]=>[data:protected]=>Array（[TableNames]=>Array（[0]=>users）））

在主机上它是空白页

我在拉威尔的日志里找到了这个

有什么想法吗？

接收BSOD最常见的情况之一是web服务器无法在应用程序/存储目录中写入。使该文件夹可写，如果无法工作，请检查php web服务器日志，或在

public/index.php

中尝试此操作，仅用于调试：

try {
    $app->run();
} catch(\Exception $e) {
    echo "<pre>";
    echo $e;
    echo "</pre>";
}

试试看{
$app->run（）；
}捕获（\异常$e）{
回声“；
echo$e；
回声“；
}

我讨厌whitescreens，它们不会告诉你任何事情，我脑海中唯一想到的就是“Composer update”你用

php artisan key:generate生成加密密钥了吗？现在你说了，我做了。Laravel现在输出此错误Aws\DynamoDb\Exception\UnrecognizedClientException请求中包含的安全令牌无效。现在是Aws问题，请尝试更改安全凭据/访问密钥，应该可以正常工作。
