Dropbox API Downloading a file Downloading a file with metadata via curl in PHP
Example
<?php
function dbx_get_file($token, $in_filepath, $out_filepath)
{
$out_fp = fopen($out_filepath, 'w+');
if ($out_fp === FALSE)
{
echo "fopen error; can't open $out_filepath\n";
return (NULL);
}
$url = 'https://content.dropboxapi.com/2/files/download';
$header_array = array(
'Authorization: Bearer ' . $token,
'Content-Type:',
'Dropbox-API-Arg: {"path":"' . $in_filepath . '"}'
);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, TRUE);
curl_setopt($ch, CURLOPT_HTTPHEADER, $header_array);
curl_setopt($ch, CURLOPT_FILE, $out_fp);
$metadata = null;
curl_setopt($ch, CURLOPT_HEADERFUNCTION, function ($ch, $header) use (&$metadata)
{
$prefix = 'dropbox-api-result:';
if (strtolower(substr($header, 0, strlen($prefix))) === $prefix)
{
$metadata = json_decode(substr($header, strlen($prefix)), true);
}
return strlen($header);
}
);
$output = curl_exec($ch);
if ($output === FALSE)
{
echo "curl error: " . curl_error($ch);
}
curl_close($ch);
fclose($out_fp);
return($metadata);
} // dbx_get_file()
$metadata = dbx_get_file("<ACCESS_TOKEN>", '/test.txt', 'test.txt');
echo "File " . $metadata['name'] . " has the rev " . $metadata['rev'] . ".\n";
?>
<ACCESS_TOKEN> should be replaced with the OAuth 2 access token.
