Question

I am trying to upload a file using a RESTful web service as follows:

$filename = "pathtofile/testfile.txt";
$handle = fopen($filename, "r");
$filecontents = fread($handle, filesize($filename));
fclose($handle);

$data = array('name' => 'testfile.txt', 'file' => $filecontents);

$client = curl_init($url);
curl_setopt($client, CURLOPT_POST, true);
curl_setopt($client, CURLOPT_POSTFIELDS, $data);
curl_setopt($client, CURLOPT_RETURNTRANSFER, 1);
curl_close($client);

But I keep gettig file is empty as a response for this request.

I tried also sending the file path like:

$data = array('name' => 'testfile.txt', 'file' => 'pathtofile/testfile.txt');
curl_setopt($client, CURLOPT_POSTFIELDS, $data);

Or: just sending the contents of the file only like:

curl_setopt($client, CURLOPT_POSTFIELDS, $filecontents);

But the same response: file is empty.

Note that: the file exists and not empty, and I am just trying to only upload the file no additional fields .

I saw this post , but the same problem, any ideas?

Try this:

$data = array ('myfile' => '@'.$filename);

This will fill $_FILE ['myfile'] for the receiving end.

Edit: to actually put the file contents as the body, you could do it directly:

//Get the file data
$body = file_get_contents ($filename);
$len = strlen ($body);

//Open a direct connection to the server on port 80
$socket = fsockopen ('hostname.example.com', 80);

//Write the HTTP request headers
fwrite ($socket, "POST /path/to/url HTTP/1.1\r\n");
fwrite ($socket, "Host: hostname.example.com\r\n");
fwrite ($socket, "Connection: Close\r\n");
fwrite ($socket, "Content-Length: " . $len . "\r\n");

//Empty line marks end of headers, start of body
fwrite ($socket, "\r\n");

//Actually write the body
fwrite ($socket, $body);

//Get the result (half a kB at a time)
$result = '';
while (!feof ($socket)) $result .= fread ($socket, 512);

//Clean up nicely
fclose ($socket);

Note that that code is untested, but it should give you the general idea.
