header array invalid request for token auth php
I have been trying to get the header array for my php curl working. This is the structure of it.
$http_headers = array( "Authorization: " . base64_encode($app_key . ":" . $app_secret), "Content-Type: application/x-www-form-urlencoded", "Dropbox-API-Arg: " . json_encode(array( 'code' => $code, 'grant_type' => 'authorization_code', 'redirect_url' => 'http://localhost:8080/FSUInnovation/ResumeUpload.php' )));
I get this error:
{"error_description": "No auth function available for given request", "error": "invalid_request"}400
I don't know what particular syntax issue is causing a problem for this particular request. I tried to base it off of my curl for file upload and download.
You should send them as POST parameters, encoded using "application/x-www-form-urlencoded", not headers. Here's a basic example I just put together for calling /oauth2/token using curl in PHP:
$app_key = "<APP_KEY>"; $app_secret = "<APP_SECRET>"; $headers = array("Authorization: Basic " . base64_encode($app_key . ":" . $app_secret), "Content-Type: application/x-www-form-urlencoded"); $authorization_code = "<AUTHORIZATION_CODE>"; $redirect_uri = "<REDIRECT_URI>"; $params = array("code" => $authorization_code, "grant_type" => "authorization_code", "redirect_uri" => $redirect_uri); $ch = curl_init('https://api.dropboxapi.com/oauth2/token'); curl_setopt($ch, CURLOPT_HTTPHEADER, $headers); curl_setopt($ch, CURLOPT_POST, true); curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($params)); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); $response = curl_exec($ch); echo $response; if (curl_errno($ch)) { echo 'Error:' . curl_error($ch); } curl_close($ch);

When using "Basic" authorization, your "Authorization" header value should start with the string "Basic ". So, that line should look like:
"Authorization: Basic " . base64_encode($app_key . ":" . $app_secret),
Also, note that the /oauth2/token endpoint is based on the OAuth spec and doesn't work like the other Dropbox API endpoints. Specifically, it doesn't take a "Dropbox-API-Arg" header. You should be specifiy those parameters as 'application/x-www-form-urlencoded' POST parameters, not JSON in a header or body.
Do the other parameters need to be in a assosiative array appended to the Content Type element like I would do with the API Args, or do I need to post those parameters like this: "code: " . $code, ... ?
