help with PUT and CURLOPT_READFUNCTION
2008-05-01 17:13:22 GMT
Hi!
I can successfully PUT a file using CURLOPT_PUT, CURLOPT_INFILE, and CURLOPT_INFILESIZE. However, for large files ( > ~100MB) my machine runs out of memory so I want to be able to "stream" the file to the webserver (instead of storing it in memory and then sending) via CURLOPT_READFUNCTION. Unfortunately, I can't get this to work and cannot find any working examples online. I've given both my working and non-working code below. Interestingly, method 1 below (which does not work) takes about 30 seconds to PUT, while method 2 (works) happens practically instantly.Any help is truly appreciated!
========= DOES NOT WORK =========
if ($method == 'PUT')
{
$this->fp = fopen($file, 'r');
$this->fileSize = filesize($file);
curl_s
etopt($curl, CURLOPT_CUSTOMREQUEST, 'PUT');
curl_setopt($curl, CURLOPT_READFUNCTION, array($this, 'stream_file'));
curl_setopt($curl, CURLOPT_UPLOAD,
true);
$request_headers[] = 'Content-Length: '.$this->fileSize;
$request_headers[] = "Expect: ";
$request_headers[] = "Transfer-Encoding: ";
curl_setopt($this->curl, CURLOPT_HTTPHEADER, $request_headers);
...
}
protected function stream_file($curl, $fileData, $fileSize)
{
return fread($this->fp, $this->fileSize);
}
