send file to server curl php

Question

I have small php app, that have some files inside. I want to send one of the files from one server to another server with using curl.

I already have file on server, I just need to send it to another server.

I execute the following code:

$url = "http://localhost:3919/";
$myCurl = curl_init();
curl_setopt($myCurl, CURLOPT_URL, $url);
curl_setopt_array($myCurl, array(
                CURLOPT_RETURNTRANSFER => true,
                CURLOPT_POST => true,
                CURLOPT_HEADER => false,
                CURLOPT_SAFE_UPLOAD => true,
                // CURLOPT_HTTPHEADER => array(
                //  "Content-Type: multipart/form-data"),
                CURLOPT_POSTFIELDS => array(
                    "inputFile" => new CurlFile('@' . './Files/example.docx'))
            ));

$response = curl_exec($myCurl);
curl_close($myCurl);
return $response;

But it doesn't trigger the server. So what should I do wrong?

For example in other case (other app) I use this:

$file = $_FILES["inputFile"];
curl_setopt_array($myCurl, array(
    CURLOPT_URL => $url,
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_POST => true,
    CURLOPT_HEADER => false,
    CURLOPT_SAFE_UPLOAD => true,
    CURLOPT_HTTPHEADER => array(
        "Content-Type: multipart/form-data"),
    CURLOPT_POSTFIELDS => array(
        "inputFile" => new CurlFile($file["tmp_name"], $file["type"], $file["name"]))
));

And it works perfectly.

Have you checked curl_error()? Also, you say that you want to send the file to "another" server, but you're using a local url (with an odd port for a web server too). — Patrick Q

It's my another app with localhost, where I get file. Yes, I've checked curl_error(), it's empty. — A. Gladkiy

Okay, so then what exactly does "it doesn't trigger the server" mean? Is it supposed to return something? If so, provide the code that should be generating that response as well as what the current response is. Right now you're basically just saying "it's not working", which isn't helpful. — Patrick Q

I just want to know why this code doesn't send file to server (server it's c# web api app where I set breakpoint to look at parameters that is sent from php file) — A. Gladkiy

So far, you haven't provided anything to show that it's not sending the file. Also, I'm pretty sure that if you're using CurlFile, you don't use the @ prefix. CurlFile is a replacement for that method of sending files. You should see that in your working code you don't have that. — Patrick Q

Using the curl_file_create works for me on sending files in curl.

$target_url = 'http://localhost:3919/';

$post = array (
    'file' => curl_file_create('Location of the file')
);

$ch = curl_init ($target_url);
curl_setopt ($ch, CURLOPT_POST, 1);
curl_setopt ($ch, CURLOPT_POSTFIELDS, $post);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
$msg=curl_exec ($ch);
$info = curl_getinfo($ch);

if($info['http_code'] === 200){
    $returnMessage = json_decode($msg,1);
} else {
    $returnMessage['file_type'] = 'error';
}
curl_close($ch);

maybe you need validate if exist files on your post and this a example complete:

<form enctype="multipart/form-data" encoding='multipart/form-data' method='post' action="form.php">
  <input name="uploadedfile" type="file" value="choose">
  <input type="submit" value="Upload">
</form>
<?
if ( isset($_FILES['uploadedfile']) ) {
 $filename  = $_FILES['uploadedfile']['tmp_name'];
 $handle    = fopen($filename, "r");
 $data      = fread($handle, filesize($filename));
 $POST_DATA = array(
   'file' => base64_encode($data)
 );
 $curl = curl_init();
 curl_setopt($curl, CURLOPT_URL, '<span style="color: red;">http://extserver.com/handle.php</span>');
 curl_setopt($curl, CURLOPT_TIMEOUT, 30);
 curl_setopt($curl, CURLOPT_POST, 1);
 curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
 curl_setopt($curl, CURLOPT_POSTFIELDS, $POST_DATA);
 $response = curl_exec($curl);
 curl_close ($curl);
 echo "<h2>File Uploaded</h2>";
}
?>

this is a example with encrypt the file with base64.

your external server

$encoded_file = $_POST['file'];
$decoded_file = base64_decode($encoded_file);
/* Now you can copy the uploaded file to your server. */
file_put_contents('<span style="color: red;">subins</span>', $decoded_file);

No, I already have file on server, I just need to send it to another server.

on this case you need attachment the file

When I try your example, I see this screencast.com/t/WsQkD3BHa For file path I tried 'D:\\Share\\Programs\\xampp\\htdocs\\Files\\example.docx' and ./Files/example.docx and http://localhost/Files/example.docx. But I would like url independent path to file (not hardcoded).
