从Codeigniter上传到S3存储桶

Question

Hi have the S3 bucket library in the codeigniter and I'm try to upload a file from a folder but it give me error. Much appreciated if some one could point out what I'm doing worng.

In the Module folder below code.

  $this->load->library('s3');
  $bucket = "xxxxxxxxxx";
  $file = "http://localhost/xxxx/backup/01.txt";
  $this->s3->putObjectFile($file, $bucket, 'test', S3::ACL_PUBLIC_READ);

I get the below error.

A PHP Error was encountered

Severity: User Warning
Message: S3::inputFile(): Unable to open input file: http://localhost/xxxx/backup/01.txt
Filename: libraries/S3.php
Line Number: 310

Check the inputFile method, its been used by putObjectFile. This checks whether a file or directory exists but you're using an url.

public static function inputFile($file, $md5sum = true)
{
    if (!file_exists($file) || !is_file($file) || !is_readable($file))
    {
        trigger_error('S3::inputFile(): Unable to open input file: ' . $file, E_USER_WARNING);
        return false;
    }
    return array('file' => $file, 'size' => filesize($file),
        'md5sum' => $md5sum !== false ? (is_string($md5sum) ? $md5sum :
                        base64_encode(md5_file($file, true))) : '');
}

Is this a file on your server? Just add the path of your file:

$this->load->library('s3');
$bucket = "xxxxxxxxxx";
$file = "/filesystem/backup/01.txt";
$this->s3->putObjectFile($file, $bucket, 'test', S3::ACL_PUBLIC_READ);
