Upload a file into dropbox folder - dropbox-api

Question

I have tried this to upload a file from a folder in my desktop to a folder in dropbox account.
but each time i have uploaded an empty file through this code.
How it is possible?
Below s my code:
$ch = curl_init();
$TOKEN = "asasasa";//token here
$url = 'https://content.dropboxapi.com/2/files/upload';
curl_setopt($ch,CURLOPT_URL,$url);
curl_setopt($ch,CURLOPT_POST, 1);
curl_setopt($ch,CURLOPT_RETURNTRANSFER, true);
$headers = array();
$headers[] = 'Accept: application/json';
$headers[] = 'Content-Type: multipart/form-data';
$headers[] = 'Dropbox-API-Arg:{"path":"/home/new/ofd","mode":{".tag":"add"},"autorename":false,"mute":false}';
$headers[] = "Authorization: Bearer ".$TOKEN;
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
$response = curl_exec($ch);
$droplist = json_decode($response,true);

Answer 1

You don't seem to be adding the file content to the upload call anywhere, so an empty file is expected from your code.
You can find an example of using /2/files/upload with curl in PHP below. That uses CURLOPT_INFILE to add the file content itself.
<?php
$path = 'test_php_upload.txt';
$fp = fopen($path, 'rb');
$size = filesize($path);
$cheaders = array('Authorization: Bearer <ACCESS_TOKEN>',
'Content-Type: application/octet-stream',
'Dropbox-API-Arg: {"path":"/test/'.$path.'", "mode":"add"}');
$ch = curl_init('https://content.dropboxapi.com/2/files/upload');
curl_setopt($ch, CURLOPT_HTTPHEADER, $cheaders);
curl_setopt($ch, CURLOPT_PUT, true);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'POST');
curl_setopt($ch, CURLOPT_INFILE, $fp);
curl_setopt($ch, CURLOPT_INFILESIZE, $size);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
echo $response;
curl_close($ch);
fclose($fp);
?>
<ACCESS_TOKEN> should be replaced with the OAuth 2 access token.

Upload a file into dropbox folder dropbox api v2
$dropbox_api_url = 'https://content.dropboxapi.com/2/files/upload'; //dropbox api url
$token = 'Access token value put here'; // should be replaced with the OAuth 2 access token
$headers = array('Authorization: Bearer '. $token,
'Content-Type: application/octet-stream',
'Dropbox-API-Arg: '.
json_encode(
array(
"path"=> '/'. basename($filename),
"mode" => "add",
"autorename" => true,
"mute" => false
)
)
);
$ch = curl_init($dropbox_api_url);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_POST, true);
$path = $filename;
$fp = fopen($path, 'rb');
$filesize = filesize($path);
curl_setopt($ch, CURLOPT_POSTFIELDS, fread($fp, $filesize));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
$http_code = curl_getinfo($ch, CURLINFO_HTTP_CODE);
//For display value as array object starts here
echo "<pre>";
print_r(json_decode($response));
//For display value as array object ends here
echo($response.'<br/>');
echo($http_code.'<br/>');
curl_close($ch);
