clj-http client translated from php/curl implementation fails, why?

[Joachim De Beule]

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?

Untested of course, but I think you need to use either :body or :form-params rather than :query-params to put the query-params data into the body of the post request.

They return identical data if you use http://httpbin.org/post as url ?

Solved by Gijs S., but thanks anyway, I didn't know about httpbin.org.
