php - Problems with volley passing parameters -


(check variablepost)

well, want pass params volley android current code code volley 

map<string, string> params = new hashmap<string, string>();     params.put("variablepost", "androidvolley");//****         jsonobjectrequest jsonobjreq = new jsonobjectrequest(request.method.post,             url, new jsonobject(params),             new response.listener<jsonobject>() {                  @override                 public void onresponse(jsonobject response) {                     log.d(tag, response.tostring());                     pdialog.hide();                 }             }, new response.errorlistener() {          @override         public void onerrorresponse(volleyerror error) {             volleylog.d(tag, "error: " + error.getmessage());             pdialog.hide();         }     }) {         @override         protected map<string, string> getparams() throws authfailureerror {              map<string, string> params = new hashmap<string, string>();             params.put("variablepost", "androidvolley");             return params;         }         @override         public map<string, string> getheaders() throws authfailureerror {             hashmap<string, string> headers = new hashmap<string, string>();             headers.put("content-type", "application/json; charset=utf-8");             headers.put("user-agent", "my useragent");             return headers;         }         @override         public string getbodycontenttype() {             return "application/json; charset=utf-8";         }      };         jsonobjreq.setretrypolicy(             new defaultretrypolicy(                     defaultretrypolicy.default_timeout_ms, // 2500                     defaultretrypolicy.default_max_retries, // 1                     defaultretrypolicy.default_backoff_mult)); //1f  appcontroller.getinstance().addtorequestqueue(jsonobjreq, "tag_json_obj");

want variable $ _post ["variablepost"] passed volley , save json return (for test version) 

$db = new db_connect(); $response= array(); $response["dataperfil"]= array();  mysql_query("set names 'utf8'"); $sql = sprintf("select p.nombres, p.apellidos, p.tiposangre, p.email, p.telefono, p.cuentaface, p.cuentatwitt, p.cuentagoogle, p.fondo, p.foto perfil p left join usuario u on p.iduser= u.id"); $result = mysql_query($sql) or die(mysql_error()); while ($row = mysql_fetch_array($result)) { $data_perfil = array(); $data_perfil["nombres"]= $row["nombres"]; $data_perfil["variablepost"] = $_post["variablepost"];//**** $data_perfil["foto"]= $row["foto"];  array_push($response["dataperfil"], $data_perfil); }  $response["success"] = 1; echo json_encode($response);

result in logcat 

wvolley d/mainactivity: {"dataperfil":[{"variablepost":null,"nombres":"carolina"},{"variablepost":null,"nombres":"ricardo"}]}

variablepost null.

try this:

    stringrequest jsonobjreq = new stringrequest(method.post, url, new response.listener<string>() {          @override         public void onresponse(string response) {             zeputils.log(response);             try {                 jsonobject responsejo = new jsonobject(response);                 //todo responsejo variables             } catch (jsonexception e) {             }         }      }, new response.errorlistener() {          @override         public void onerrorresponse(volleyerror error) {             //todo error();         }      }) {          @override         protected map<string, string> getparams() {             map<string, string> params = new hashmap<string, string>();             params.put("variablepost", "androidvolley");             return params;         }          @override         public map<string, string> getheaders() throws authfailureerror {             hashmap<string, string> headers = new hashmap<string, string>();             headers.put("user-agent", "useragent");             return headers;         }     };      appcontroller.getinstance().addtorequestqueue(jsonobjreq, "tag_json_obj");

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: { ...
