php亚马逊弹性代码转换器

Question

我正在尝试执行将对视频文件进行代码转换的工作...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',
        ),
));

?>

而且我将此脚本称为transcoder.php

事实是，如果我从VPS的根目录像php transcoder.php一样调用它，它就可以正常工作，但是如果我尝试从浏览器（Safari，Chrome，Firefox）调用它，我会得到一个] >

有人知道为什么它可以从根本上运行，为什么它不能从浏览器上运行？我需要从浏览器访问它。

我正在尝试执行将对视频文件进行转码的工作...我有一个php文件：

Answer 1

尝试从php.ini中更改有关curl和exec的设置，这就是为什么您没有权限从浏览器访问脚本，但可以从root控制台运行的原因。

Answer 2

首先，在代码周围放一个try/catch statement，以查看整个错误消息，这将有助于诊断问题。
