javascript - Highcharts add point to line chart with json -


i need add point data mysql database. @ time, data json don't know why in output array, data have double quote(" ") this:

["{name:'chip 3',data:[[moment('2015-05-14 13:26:21','hh:mm:ss').valueof(),29],[moment('2015-05-14 13 :26:51','hh:mm:ss').valueof(),29],[moment('2015-05-14 13:27:21','hh:mm:ss').valueof(),29],[moment('2015-05-14  13:27:51','hh:mm:ss').valueof(),29],[moment('2015-05-14 13:28:21','hh:mm:ss').valueof(),29],[moment('2015-05-14  14:42:54','hh:mm:ss').valueof(),32],]}"]

so highcharts can not access data , show data on chart. need remove double quote array or else make highcharts can regconize data.

this code in data.php file use , update series data.

<?php  header("content-type: text/json");    include_once 'include/connection.php';  $db = new db_class();          $query = "select distinct idchip datatable ";      $result = mysql_query( $query );      $rows = array();      $count = 0;      $getall = array();      while( $row = mysql_fetch_array( $result ) ) {           $table = array();           $query2 = "select datetime,temperature datatable idchip=".$row['idchip'].' group datetime ';              $dataresult = mysql_query($query2);             while($datarow = mysql_fetch_array($dataresult))             {                  $data = '';                   $datatimes .= $datarow['0'].',';                   $data .= "[moment('".$datarow['0']."','hh:mm:ss').valueof(),".(integer)$datarow['1']."],";                 $stringdata .= $data;                  }          $newstring = $stringdata ;          $stringdata = '';         $stringtime = '';          $namedata = "{name:'chip ".$row["idchip"]."',data:[$newstring]}";         $getall[] = $namedata;        }   echo json_encode($getall); ?>

this code use ajax return data.

function getdata() {         jquery.ajax({             url: 'data.php',             type: 'get',             datatype: 'json',             mimetype: 'multipart/form-data',             contenttype: false,             cache: false,             processdata: false,             success: function( data, jqxhr ) {                 if( data == "null" ) {                  } else {                   $.getjson("data.php", function(json) {              chart = new highcharts.chart({                chart: {                 renderto: 'container',                 defaultseriestype: 'spline',                 events: {                //     load: requestdata                 }             },  series: json              });         });                 }             },             error: function( textstatus ) {                 console.log(" error. damm. ");                 //console.log(error);             }         });     }

i think this

    $query = "select distinct idchip datatable ";     $result = mysql_query( $query );     $rows = array();     $count = 0;     $getall = array();     while( $row = mysql_fetch_array( $result ) ) {          $table = array();         $stringdata = array();         $query2 = "select datetime,temperature datatable idchip=".$row['idchip'].' group datetime ';          $dataresult = mysql_query($query2);          $stringdata = array();         while($datarow = mysql_fetch_array($dataresult))         {             $stringdata[] = "moment('".$datarow['0']."','hh:mm:ss').valueof(),".(integer)$datarow['1'];         }          $namedata['name'] = "chip ".$row["idchip"];         $namedata['data'] =  $stringdata;         $getall[] = $namedata;     }      echo json_encode($getall);

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: { ...
