Files Uploaded are Corrupted After api usage
I tried uploading various documents of types ms word doc and pdf to the site using the standard fread method in my curl postfields input. The files are corrupted and cannot be repaired by a word proc...
I see you're adding a layer of base64 encoding via your call to base64_encode. You should not base64 encode the file data when uploading it. Try removing that base64_encode call.
$dropbox_url_upload = "https://content.dropboxapi.com/2/files/upload";
$opendoc = fopen($filename, 'rb');
$docsize = $doc['size'];
$d1curl = curl_init();
curl_setopt($d1curl, CURLOPT_URL, $dropbox_url_upload);
curl_setopt($d1curl, CURLOPT_TIMEOUT, $timeout);
curl_setopt($d1curl, CURLOPT_HTTPHEADER, [
utf8_encode('Authorization: Bearer ' . $dropbox_token),
'Content-Type: application/octet-stream',
'Dropbox-API-Arg: '.
json_encode(
array(
"path"=> $dropbox_directory,
"mode" => "add",
"autorename" => true,
"mute" => false
))]);
curl_setopt($d1curl, CURLOPT_POST, true);
curl_setopt($d1curl, CURLOPT_POSTFIELDS, base64_encode(fread($opendoc, $docsize)));
curl_setopt($d1curl, CURLOPT_RETURNTRANSFER, true);
$dropbox_upload = curl_exec($d1curl);
$http_request = curl_getinfo($d1curl, CURLINFO_HTTP_CODE);
echo $dropbox_upload;
echo $http_request;
curl_close($d1curl);
fclose($opendoc);

It is working now and am able to view the contents on my dropbox viewer. However, when I tried doing it without any encoding yesterday, I also had corruption. What could increase the risk of file corruption when uploading with the api?

There's no reason an upload without extra encoding like that should result in a corrupted file.
If you can reproduce an issue where correct code and a valid original file results in a corrupted file when uploaded to Dropbox via the API, please share the steps and code to reproduce it so we can look into it.
