php亚马逊弹性转码器

Question

我正在尝试执行一个对视频文件进行转码的工作......我有一个 php 文件:

<?php
require 'vendor/autoload.php';

use Aws\ElasticTranscoder\ElasticTranscoderClient;

// Create a service locator using a configuration file
$client = ElasticTranscoderClient::factory(array(
        'key'    => 'my key',
        'secret' => 'my secret',
        'region' => 'us-west-2',
));

$result = $client->createJob(array(
        'PipelineId' => 'my pipeline id',
        'Input' => array(
                'Key' => 'video.mp4',
                'FrameRate' => 'auto',
                'Resolution' => 'auto',
                'AspectRatio' => 'auto', 
                'Interlaced' => 'auto',
                'Container' => 'auto',
        ),
        'Output' => array(
                'Key' => 'output.mp4',
                'ThumbnailPattern' => 'thumb{count}.jpg',
                'Rotate' => 'auto',
                'PresetId' => '1351620000001-000010',
        ),
));

?>

我把这个脚本称为 transcoder.php

问题是，如果我从 VPS 的根目录调用它，例如 php 转码器.php 它工作得很好，但如果我尝试从我的浏览器(safari、chrome、firefox)调用它，我会得到一个

Fatal error: Uncaught exception 'Aws\ElasticTranscoder\Exception\ElasticTranscoderException' in /home/my_user/public_html/test/vendor/aws/aws-sdk-php/src/Aws/Common/Exception/NamespaceExceptionFactory.php:91

知道为什么它可以从 root 运行以及为什么它不能在浏览器中运行吗？我需要从浏览器访问它。

Answer 1

尝试从 php.ini 更改有关 curl 和 exec 的设置，这就是为什么您无权从浏览器访问脚本，但可以从根控制台访问。
