Tradeking / Ally Invest API PHP的市场报价请求

Question

I am trying to use the Ally Invest/ Tradeking PHP API to request a market quote: https://www.ally.com/api/invest/documentation/market-ext-quotes-get-post/

Using the documentation, I installed PHP OAuth and I created the below code, but it doesnt seem to yield an output when i make the call:

$consumer_key     = 'Z3fPyf181adB63Gq4gQZAjL1b7xgx7jLGA92DQ9jnuk4';
$consumer_secret  = 'feDtEmHTWoRb4rDMZkF6gvXj0xd2lP5vGDXPCUiZJww7';
$access_token     = '251cgNlYK21b6tqbqYSImAiqJKk3c51lHu4UOOF71ZI4';
$access_secret    = 'aLth5Imx0VgB67IgFhDxmW3QVYKPxdtzNMmjbiNWYXI7';

$oauth = new OAuth($consumer_key,$consumer_secret,OAUTH_SIG_METHOD_HMACSHA1,OAUTH_AUTH_TYPE_AUTHORIZATION);
$oauth->setToken($access_token,$access_secret);
$noonce=date('U') ;
$oauth->setNonce($noonce);
$signature= $oauth->generateSignature("GET", "https://api.tradeking.com/v1/market/ext/quotes.xml?symbols=fb");
$url = 'https://api.tradeking.com/v1/market/ext/quotes.xml?symbols=fb';
$header = [
    "GET /v1/market/ext/quotes.xml?symbols=fb HTTP/1.1 
" .
    "Authorization: OAuth 
" .
    'oauth_consumer_key="'.$consumer_key.'"' . " 
" .
    'oauth_nonce="'.$noonce.'"' .  " 
" .
    'oauth_signature="'.$signature.'"' . " 
" .
    'oauth_signature_method="HMAC-SHA1"' . " 
" .
    'oauth_timestamp="'.time().'"' . " 
" .
    'oauth_token="'.$access_token.'"' . " 
" .
    'oauth_version="1.0"' . " 
" .
    'Connection: close' . " 
" .
    'Host: api.tradeking.com'

];
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_HTTPHEADER,$header);
$response = curl_exec($ch);

You don't need to manually build the HTTP header -- PHP's OAuth library will do it for you. This is all you need:

$oauth = new OAuth($consumer_key,$consumer_secret,OAUTH_SIG_METHOD_HMACSHA1,OAUTH_AUTH_TYPE_AUTHORIZATION);
$oauth->setToken($access_token,$access_secret);
$url = 'https://api.tradeking.com/v1/market/ext/quotes.xml?symbols=fb';
$oauth->fetch($url);
print($oauth->getLastResponse());
