android :

 try {                 jsonobject obj = new jsonobject();                 obj.put("id", editid.gettext().tostring());                 obj.put("pw", editpassword.gettext().tostring());                 final string jsonstring = obj.tostring();                 //final string jsonstring = "{\"id=\":\"abce\",\"pw\":\"13447\"}";                 log.i("tag",jsonstring);                 thread background = new thread(new runnable() {                     @override                     public void run() {                         try {                             log.i("tag", "thread");                             url url = new url("http://49.172.86.247:80/login/controller_on");                             httpurlconnection hey = (httpurlconnection) url.openconnection();                             hey.setrequestmethod("post");                             hey.setdoinput(true);                             hey.setdooutput(true);                             hey.setrequestproperty("content-type", "application/json");                             hey.setconnecttimeout(10000);                             hey.setusecaches(false);                              dataoutputstream wr = new dataoutputstream(hey.getoutputstream());                              inputstream inputstream = hey.getinputstream();                             wr.writebytes(jsonstring.tostring());                             wr.flush();                             wr.close();                          } catch (exception e) {                             log.e("tag","error");                         }

server : 

app.post('/login/:termtype', function(req, res){     console.log(req.body);  });
