Dear list,
[Sorry if this may be a bit of topic, but I don't know much about php and
http, and I'm not sure where else to turn]
I'm trying to port a working php api client implementation to clojure.
So on the one hand, I've got the following working php code for performing
a signed post request:
function perform_request($url, $method, $key, $secret) {
$query_params['method'] = $method;
$mt = explode(' ', microtime());
$query_params['nonce'] = $mt[1]*1000;
$query_string = http_build_query($query_params, '', '&');
$sign = hash_hmac("sha512", $query_string, $secret);
$headers = array(
'sign: '.$sign,
'key: '.$key,
);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POSTFIELDS, $query_string);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
$res = curl_exec($ch);
return $res;
}
On the other hand, I've got the following clojure code which, as far as I
can tell, performs an identical request (I've checked that the signatures
are the same in both implementations):
(defn perform-request [url method key secret]
(let [query-params {:method method
:nonce (clj-time.coerce/to-long
(clj-time.core/now))}
query-string (clj-http.client/generate-query-string query-params)
signature (pandect.core/sha512-hmac query-string secret)]
(clj-http.client/post url
{:query-params query-params
:headers {"sign" signature
"key" key}})))
Unfortunately, the clojure code always returns with an "unable to authorize
request, check post data" response from the remote service, and I don't
understand why? Is it possible that the default client settings in php/curl
are different from those in clj-http or something, i.e. maybe I need to
disable/add some clj-http request wrappers or something?
