Post File as an Attachment Using Confluence Rest API with PHP curl

[Coline Macorol]

Hello All,

I have trying for quite awhile to post a file as an attachment using the rest api with php curl. I have seen similar questions out there, and I tried to emulate those who said they had success, but it just does not seem to work for me. I would greatly appreciate and welcome any suggestions.

My code:

$ch = curl_init();
$file = 'C:\path\path\path\path.txt';

if (function_exists('curl_file_create')) {
     $cFile = curl_file_create($file);
} else { 
     $cFile = '@' . realpath($file);
}
$postData = array('file_contents' => $cFile);
$headers = array();
$headers[] = "X-Atlassian-Token: no-check"; 

curl_setopt($ch, CURLOPT_URL, "http://localhost:8090/rest/api/content/31391748/child/attachment");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_USERPWD, "****" . ":" . "****");
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postData);

$result = curl_exec($ch);
$info = curl_getinfo($ch);
print_r($info);
curl_close ($ch);

I noticed I am getting a HTTP code of 400 when $info prints, which I know means it is a bad request. I am not sure what could potentially be causing this. Again, any help will be much appreciated!

Dear @Coline Macorol ,

as written in the API document:

The name of the multipart/form-data parameter that contains attachments must be "file"

Replace

$postData = array('file_contents' => $cFile);

with 

$postData = array('file' => $cFile);

So long

Hi all,

I'm unfortunately back to say the php curl is once again not working. Thanks to php curl error handling, it appears the problem is cURL error (26): Failed to open/read local data from file/application.

I know this means it is unable to open the file it is pointing to. However, I don't know why it isn't, especially since it worked before and I haven't changed anything but the file. Could it be the file path? Or is it something else I'm not seeing?

Thanks,

Coline Macorol
