Dropbox download_zip api
I use api https://www.dropbox.com/developers/documentation/http/documentation#files-download_zip to download files from a folder, but I always get an error in call to API function "files / download_z...
here is my sample code, i think here everything is right $ch = curl_init(); curl_setopt($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 $token'; $headers[] = 'Dropbox-Api-Arg: {\"path\": \"/test/"}'; $headers[] = "Content-Type: application/octet-stream"; curl_setopt($ch, CURLOPT_HTTPHEADER, $headers); $result = curl_exec($ch); if (curl_errno($ch)) { echo 'Error:' . curl_error($ch); } curl_close($ch);
You can also use the API v2 Explorer to prototype these calls for you. It will build the header for you, and can even show you the code for making the call.
I used this, I generated the code, but it doesn't work

Dropbox StaffThanks 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

I see this was also opened as a new thread, so I'll take a look and reply on that one:
