如何使用 Codeigniter/PHP 将文件上传到亚马逊 S3？

Question

我正在尝试将文件上传到我的 Amazon S3 存储桶。我的朋友过去曾在我们的网站上进行过这项工作，但一年后它被破坏了，我不知道出了什么问题。我们使用的是Geoff gaudreault开发的S3 PHP library。

这个库对我来说看起来很简单，实际上它看起来有一个关键功能：putObject()。

不幸的是，我什至没有走出大门。我收到以下错误消息： Error 324 (net::ERR_EMPTY_RESPONSE): The server closed the connection without sending any data.

这是我的上传表单action的codeigniter PHP：

    function s3(){

    $config['upload_path'] = $_SERVER["DOCUMENT_ROOT"].'/temp/';
    $config['allowed_types'] = 'gif|jpg|png';
    $config['max_size'] = '1000000';
    $config['max_width']  = '1024000';
    $config['max_height']  = '768000';

    $this->load->library('upload', $config);

    if ( ! $this->upload->do_upload())
    {
        $error = array('error' => $this->upload->display_errors());

        print_r($error);
        echo 'failure';
    }
    else
    {
       $data = array('upload_data' => $this->upload->data()); 
        $fn = $data['file_name'];
        $type = substr($fn, strrpos($fn, '.') + 1);

    $this->load->library('s3');
    $temp_file_path = $_SERVER["DOCUMENT_ROOT"]."/temp/" . $data['file_name'];
    $contents = read_file($temp_file_path); // will this blow up or timeout for large files?! 
    $newFileName = uniqid().".".substr($temp_file_path, strrpos($temp_file_path, '.') + 1);
     $contentPath = "mysite.com/Images"; 

    $this->s3->putObject($newFileName, $contents, $contentPath, 'private', $type);
    echo 'success';
    }
}

有人有什么想法吗？

Answer 1

我切换到different S3 PHP library，也称为 S3.php，这是这个非常好的 Netuts 教程源代码的一部分。

只需将我的 AWS 密钥和存储桶名称插入演示的 page.php 文件，我就可以在 2 分钟内上传到我的存储桶。所以这个教程超级简单。非常令人兴奋！

在代码点火器中
