I was reading the tutorial here beause I don’t know anything about oauth. I got to this point…
$after_access_request = doHttpRequest($access_token_req->to_url());
parse_str($after_access_request,$access_tokens);
$access_token = new OAuthConsumer($access_tokens['oauth_token'], $access_tokens['oauth_token_secret']);
However when testing there isn’t an index $acccess_tokens[oauth_token_secret]. I did a dump of the values I was getting which were the following.
[url/oauth/request_token?oauth_consumer_key] => key
[oauth_nonce] => key
[oauth_signature] => key
[oauth_signature_method] => HMAC-SHA1
[oauth_timestamp] => 1374688924
[oauth_token] => key
[oauth_version] => 1.0errorInvalid OAuth request
I replaced all of the keys with “key” since I’m not sure what they are used for and feel it would be really bad to simply post them here. As you can see though there is no oauth_consumer_secret also oauth_version has a strange string in it that says it was an invalid oauth request. I’ll include the whole code below.
function doHttpRequest($urlreq)
{
$ch = curl_init();
// set URL and other appropriate options
curl_setopt($ch, CURLOPT_URL, "$urlreq");
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, true);
// grab URL and pass it to the browser
$request_result = curl_exec($ch);
// close cURL resource, and free up system resources
curl_close($ch);
return $request_result;
}
//helper function to get the stream_key from returned XML
function parseStream_KeyFromXML($xml)
{
$xml_parser = xml_parser_create();
xml_parse_into_struct($xml_parser, $xml, $vals, $index);
xml_parser_free($xml_parser);
if ($vals[1]['tag'] == "STREAM_KEY")
return $vals[1]['value'];

$sig_method = new OAuthSignatureMethod_HMAC_SHA1();

$params = array(callback => $base_url);
