Thanks for the additional information. I see you have extra \ values in your JSON string. You may have copied those from the command-line curl examples in the documentation. Those are only needed in contexts where you need to escape the subsequent " values, such as in bash, like in those examples, since the " character is already used to start the string for the header parameter for curl itself.

Since that doesn't apply to your PHP context, you shouldn't include them as they'll be sent as-is, corrupting the JSON string. Instead, you'd just want something like:

$headers[] = 'Dropbox-Api-Arg: {"path": "/test"}';

I do recommend having some other library or method build those JSON strings for you instead though.

function dropbox_download_zip($folder_path, $file_name) { $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, 'https://content.dropboxapi.com/2/files/download_zip'); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_POST, 1); $headers = array(); $headers[] = "Authorization: Bearer " . DROPBOX_TOKEN . ""; $headers[] = "Dropbox-API-Arg: {\"path\": \"$folder_path\"}"; $headers[] = "Content-Type: application/octet-stream; charset=utf-8"; curl_setopt($ch, CURLOPT_HTTPHEADER, $headers); $result = curl_exec($ch); curl_close($ch); if (curl_errno($ch)) { echo 'Error:' . curl_error($ch); } else { $file_name = $file_name . '.zip'; file_put_contents(get_home_path() . '/' . $file_name, $result); $zipFilePath = get_home_path() . $file_name; $zipBaseName = basename($zipFilePath); header("Content-Type: application/zip"); header("Content-Disposition: attachment; filename=$zipBaseName"); header("Content-Length: " . filesize($zipFilePath)); readfile($zipFilePath); unlink($zipFilePath); die(); } }

here is my code, but it only works on a local server, on a real site it produces such an error, why? https://monosnap.com/file/0Dxbpzchbiq8ngZRl42SNEHqbCvmi1
