java - How to call Json Post request with queryparam on client side? -

i wrote both service , client part of application. tested service "postman" application , working fine url = http://192.168.2.50:8084/facebusinessservice/webresources/service/login?phone=123456789&password=1234

however when try call on android application not working. while debuging on service side see phone , password parameters null.

here service side :

    @path("login")     @post     @produces("application/json")     public string postjson(@queryparam("phone")string phone, @queryparam("password") string password) {          string info = null;               try {             userinfo userinfo  = null;             usermodel usermodel = new usermodel();             userinfo = usermodel.ispersonregistered(phone, password);              gson gson = new gson();             system.out.println(gson.tojson(userinfo));             info = gson.tojson(userinfo);                                 } catch (exception e) {             system.out.println("exception: " + e.getmessage());         }          return info;     } 

here android app side :

    private userinfo loginuser(string phone, string password) {         userinfo userinfo = null;          httpclient httpclient = new defaulthttpclient();         httppost post = new httppost("http://192.168.2.27:8084/facebusinessservice/webresources/service/login");           try {             /*             multipartentity entity = new multipartentity(httpmultipartmode.browser_compatible);             entity.addpart("phone", new stringbody(phone));             entity.addpart("password", new stringbody(password));              post.setentity(entity);             */              list<namevaluepair> params = new arraylist<namevaluepair>(2);             params.add(new basicnamevaluepair("phone", phone));             params.add(new basicnamevaluepair("password", password));             post.setentity(new urlencodedformentity(params, "utf-8"));               log.d(tag, "post string: " + post.tostring());              try {                 httpresponse response = httpclient.execute(post);                  if (response.getentity().getcontentlength() > 0) {                     string json_string = entityutils.tostring(response.getentity());                     jsonobject jsonobject = new jsonobject(json_string);                      // todo                      return userinfo;                 }               } catch (ioexception e) {                 e.printstacktrace();                 return null;             } catch (jsonexception e) {                 e.printstacktrace();                 return null;             }          } catch (unsupportedencodingexception e) {             e.printstacktrace();             return null;         }          return null;     } 

i tried both multipartentity , namevaluepair none of them worked. give me idea how handle issue?

note when testing postman passed parameters (user name , password) part of url (url encoded), can directly retrieved on server side. (you don't need post request this). objects passed string objects, not json objects.

in client code , url different because you're encoding parameters part of post request entity (payload). parameters packaged inside of request/message body , not in url.

now since url doesn't have parameters, should retrieve them deserializing request (desderialize json request userinfo object).

note should rewrite server side code should accept application/json object apparently should return/produce string object (plain/text or application/html).

i'm not familiar gson code might like

@path("login") @post @produces("text/plain") @consumes("application/json") public string postjson(userinfo ui) {      string info = null;           try {         userinfo userinfo  = null;         usermodel usermodel = new usermodel();         userinfo = usermodel.ispersonregistered(ui.phone, ui.password);          gson gson = new gson();         system.out.println(gson.tojson(userinfo));         info = gson.tojson(userinfo);                             } catch (exception e) {         system.out.println("exception: " + e.getmessage());     }      return info; }
