this jsonparser class:

public class jsonparser {      static inputstream = null;     static jsonobject jobj = null;     static string json = "";      // constructor     public jsonparser() {      }      // function json url     // making http post or mehtod     public jsonobject makehttprequest(string url, string method,         list<namevaluepair> params) {          // making http request         try {              // check request method             if(method.equals("post"){                 // request method post                 // defaulthttpclient                 defaulthttpclient httpclient = new defaulthttpclient();                 httppost httppost = new httppost(url);                 httppost.setentity(new urlencodedformentity(params));                  httpresponse httpresponse = httpclient.execute(httppost);                 httpentity httpentity = httpresponse.getentity();                 = httpentity.getcontent();              } else if (method.equals("get") {                 // request method                 defaulthttpclient httpclient = new defaulthttpclient();                 string paramstring = urlencodedutils.format(params, "utf-8");                 url += "?" + paramstring;                 httpget httpget = new httpget(url);                  httpresponse httpresponse = httpclient.execute(httpget);                 httpentity httpentity = httpresponse.getentity();                 = httpentity.getcontent();             }                     } catch (unsupportedencodingexception e) {             e.printstacktrace();         } catch (clientprotocolexception e) {             e.printstacktrace();         } catch (ioexception e) {             e.printstacktrace();         }          try {             bufferedreader reader = new bufferedreader(new inputstreamreader(is, "iso-8859-1"), 8);             stringbuilder sb = new stringbuilder();             string line = null;             while ((line = reader.readline()) != null) {                 sb.append(line + "\n");             }             is.close();             json = sb.tostring();         } catch (exception e) {             log.e("buffer error", "error converting result " + e.tostring());         }          // try parse string json object         try {             jobj = new jsonobject(json);         } catch (jsonexception e) {             log.e("json parser", "error parsing data " + e.tostring());         }          // return json string         return jobj;     } }

this login asynctask:

class attemptlogin extends asynctask<string, string, string> {      /**      * before starting background thread show progress dialog      * */     boolean failure = false;      @override     protected void onpreexecute() {         super.onpreexecute();         pdialog = new progressdialog(login.this);         pdialog.setmessage("attempting login...");         pdialog.setindeterminate(false);         pdialog.setcancelable(true);         pdialog.show();        }      @override     protected string doinbackground(string... args) {          int success;         string emailaddress = eadd.gettext().tostring();         string password = pass.gettext().tostring();          list<namevaluepair> params = new arraylist<namevaluepair>();         params.add(new basicnamevaluepair("mem_email", emailaddress));         params.add(new basicnamevaluepair("mem_password", password));          log.d("request!", "starting");          jsonobject json = jsonparser.makehttprequest("http://builtcycles.com/built_mobile/login.php", "post", params);          // check log json response         log.d("login attempt", json.tostring());         // json success tag         try{             success = json.getint("success");              if (success == 1) {                 string memberid = json.getstring("id");                 string membername = json.getstring("uid");                  log.d("login successful!", json.tostring());                 pdialog.dismiss();                  intent = new intent(login.this, mainactivity.class);                  intent.putextra("id", memberid);                 intent.putextra("uid", membername);                  startactivity(intent);                 finish();                  return json.getstring("message");                    } else {                 log.d("login failure!", json.getstring("message"));                 return json.getstring("message");             }          } catch (exception e) {             e.printstacktrace();         }          return null;     }      /**      * after completing background task dismiss progress dialog      * **/      @override     protected void onpostexecute(string file_url) {          pdialog.dismiss();          if (file_url != null) {             toast.maketext(login.this, file_url, toast.length_short).show();         }     } }

and login php:

<?php     $response = array();     if (!empty($_post)) {          $email= $_post['mem_email'];          // include db connect class         require_once __dir__ . '/db_connect.php';          // connecting db         $db = new db_connect();          // mysql inserting new row         $result = mysql_query("select * tblmembers mem_email='$email'");          if (mysql_num_rows($result) > 0) {             while ($row = mysql_fetch_array($result)) {                 $response["id"] = $row["mem_id"];                 $response["uid"] = $row["mem_fname"];                  if ($row["mem_active"]==1) {                     if (md5($_post['mem_password'])===$row['mem_password']) {                          $response["success"] = 1;                         $response["message"] = "login successfully!";                          echo json_encode($response);                     } else {                          $response["success"] = 0;                         $response["message"] = "invalid email or password";                          echo json_encode($response);                                                  }                 } else {                     $response["success"] = 3;                     $response["message"] = "check email verification! thanks.";                      echo json_encode($response);                  }             }         } else {             // no products found             $response["success"] = 4;             $response["message"] = "no user found";              // echo no users json             echo json_encode($response);         }        } else {         $response["success"] = 4;         $response["message"] = "fields empty.";          // echo no users json         echo json_encode($response);     } ?>

i have changed method == "post"/"get" method.equals("post"). still, not able send data server. problem coming jsonparser class, or in doinbackground() of asynctask?

change string comparison statements in 

makehttprequest()

from

// check request method if(method == "post"){   ... } else if (method == "get") {

to

// check request method if(method.equals("post")){   ... } else if (method.equals("get")) {

javascript - Complete OpenIDConnect auth when requesting via Ajax -

the normal openidconnect server works like: you go a.com/secure-resource you 302 server your browser handles , sends identity server you login there it sends a.com via post you logged in on a.com , a.com/secure-resource on browser. however have scenario i'm trying solve need help. the user logged in on idserver the user logged in on a.com the user not logged in on b.com we need send ajax call web server b.com (from domain a.com ) b.com configured use openidconnect. but because request b.com via ajax, user cannot redirected idserver. (all in response 302 ) we can go ahead , handle 302 via ajax (i'm still not sure whether work, security-wise). but is there scenario in identityserver/openidconnect designed these situations? with identityserver in scenario setup server b.com use bearer token authentication, need use access token provided a.com in headers of ajax call $.ajax({ url: 'http://b.com', headers: { ...
