Bad HTTP "Content-Type" header

heisenberg41

Hello,

I am writing a simple app that creates some folders when we add a new client to our systems.

I keep getting an error:

Error in call to API function "files/create_folder_batch": Bad HTTP "Content-Type" header: "application/json; boundary=------------------------0e03e86aa71fa792". Expecting one of "application/json", "application/json; charset=utf-8", "text/plain; charset=dropbox-cors-hack".

Here is the code that I am using:

function create_folders() {
	$ch = curl_init();
	$folders = array(
	    "/B - Client Folders/" . $folder_name, 
	    "/B - Client Folders/" . $folder_name . "/Logo", 
	    "/B - Client Folders/" . $folder_name . "/Photos", 
	    "/B - Client Folders/" . $folder_name . "/Graphics"
	    );

	$params = array(
	    $folders, 
	    '"autorename":false', 
	    '"force_async":false');

	curl_setopt($ch, CURLOPT_URL, 'https://api.dropboxapi.com/2/files/create_folder_batch');
	curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
	curl_setopt($ch, CURLOPT_POST, 1);
	curl_setopt($ch, CURLOPT_POSTFIELDS, $params);

	curl_setopt($ch, CURLOPT_HTTPHEADER, array(
	    'Authorization: Bearer <key>',
	    'Dropbox-Api-Path-Root: {".tag": "namespace_id", "namespace_id": "<nsid>"}',
	    'Content-Type: application/json'));

	$result = curl_exec($ch);
	if (curl_errno($ch)) {
		echo 'Error:' . curl_error($ch);
	} else {echo $result;}
	curl_close($ch);
}

I don't understand why "; boundary=------------------------0e03e86aa71fa792" is being added to "application/json".

Thanks for your help in advance.

It looks like you're just passing along a native object as the API call parameters, and curl is then applying the multi-part Content-Type. You should send up the parameters as JSON.

You can build your parameters as JSON like:

$params = json_encode(array(
    'paths'=> $folders,
    'autorename'=> false,
    'force_async'=> false));
