Question

我正在尝试按照我在YouTube上找到的教程

将文件从php脚本上传到s3

我有以下php文件

upload.php的

use Aws\S3\Exception\S3Exception;

require 'start.php';

if(isset($_FILES['file'])){
    $file=$_FILES['file'];

    $name = $file['name'];
    $tmp_name = $file['tmp_name'];

    $file_ext = explode('.', $name);
    $file_ext = strtolower(end($file_ext));

    $key = md5(uniqid());
    $tmp_file_name = "{$key}.{$file_ext}";
    $tmp_file_path = "../files/{$tmp_file_name}";

    move_uploaded_file($tmp_name, $tmp_file_path);
    try{
        $s3 -> putObject([
                'Bucket' => $config['s3']['bucket'],
                'Key' => 'uploads/{$key}.{$name}',
                'Body' => fopen($tmp_file_path, 'rb'),
                'ACL' => 'public-read'

        ]);

        unlink($tmp_file_path);
    }catch(S3Exception $e){
        die("Error uploading file");
    }


}

?>

<html>
    <head>
        <title>Upload</title>
    </head>
    <body>
        <form action="upload.php" method="post" enctype="multipart/form-data">
            <input type="file" name="file">

            <input type="submit" value="Upload">
        </form>
    </body>
</html>

Start.php

'最新'， 'region'=＆gt; '美东-1' ]）; ？＆GT;

的config.php

<?php

return [
    's3' => [
        'bucket' => 'umnbucket2016'
    ]
];
?>

我在〜/ .aws /凭证的文件包含[默认]而不是我的密钥和密钥

当我尝试上传文件时，我收到以下错误

 Fatal error: Uncaught exception 'Aws\Exception\CredentialsException' with message 'Error retrieving credentials from the instance profile metadata server. (Error creating resource: [message] fopen(http://169.254.169.254/latest/meta-data/iam/security-credentials/): failed to open stream: Connection timed out [file] /var/www/html/AWS/vendor/guzzlehttp/guzzle/src/Handler/StreamHandler.php [line] 282)' in /var/www/html/AWS/vendor/aws/aws-sdk-php/src/Credentials/InstanceProfileProvider.php:79 Stack trace: #0 /var/www/html/AWS/vendor/guzzlehttp/promises/src/Promise.php(199): Aws\Credentials\InstanceProfileProvider->Aws\Credentials\{closure}(Array) #1 /var/www/html/AWS/vendor/guzzlehttp/promises/src/Promise.php(152): GuzzleHttp\Promise\Promise::callHandler(2, Array, Array) #2 /var/www/html/AWS/vendor/guzzlehttp/promises/src/TaskQueue.php(60): GuzzleHttp\Promise\Promise::GuzzleHttp\Promise\{closure}() #3 /var/www/html/AWS/vendor/guzzlehttp/promises/src/Promise.php(240): GuzzleHttp\Promise\TaskQueue->run(true) #4 /var/www/html/AWS in /var/www/html/AWS/vendor/aws/aws-sdk-php/src/Credentials/InstanceProfileProvider.php on line 79

我最初有config.php存储我的密钥和秘密ID，但改为支持凭证文件

任何帮助将不胜感激。

你得到的错误是一个线索：

的fopen（http://169.254.169.254/latest/meta-data/iam/security-credentials/）：无法打开流：连接超时

该库正在尝试访问安全凭证元数据，但正在超时。

您能否确认可以从实例内部打开该URL？当然，此代码应位于正在运行的AWS实例上，并且应该可以访问元数据URL。

可能存在导致该网址被阻止的问题。防火墙吗？安全组？

从实例配置文件元数据服务器检索凭据时出错
