javascript - ajax can not recieve JSON from php -


i have issues receiving json object php. can alert , ( think correct) json object datatype: 'text', not use data.message --> "undefined". datatype: 'json','jsonp' or ajax call $.getjson not work (it not fire request).

ajax

$('#login').click(function () { var name = $('#username').val(); var pass = $('#password').val(); $.ajax({     url: "http://localhost/weltenbummler/weltenbummler1/weltenbummler1/app/login.php?username=" + name + "&password=" + pass,     datatype: 'text',     type: 'get',     success: function (d) {         alert(d);         alert(d.message);     } });});

alerted jsons

{"status":"f","message":"benutzername und passwort stimmen nicht ueberein"} or

{"status":"t","message":"erfolgreich eingeloggt!","data":{"id":"1","mail":"abc","password":"123"}}

i tested recieved string on jsonlint.com , should valid. tried json.parse(data) , $.parsejson(data) not work. json.stringify(data) returning json slashes (i not know why).

postman can read aswell in html, text, xml or json...

in php tried change header header("content-type: application/json; charset=utf-8"); or force response json.

connect.php file:

<?php $host = "127.0.0.1"; $user= "root"; $pw=""; $db = "weltenbummler";  //create connection $con = new mysqli($host,$user,$pw,$db);   //check connection if($con->connect_error){     die("connection failed: " .$con->connect_error); }?>

login.php file:

<?php header('content-type: application/json'); require 'connect.php';  $username = $_get['username']; $password = $_get['password'];  $response = array(); if(empty($username)){     $response = array(         "status " => " f",         "message " => " gebe einen benutzernamen ein!"     );     die(json_encode($response)); } if(empty($password)){     $response = array(         "status" => "f",         "message"=> "gebe ein passwort ein!"     );     die(json_encode($response)); }  $sqlstatement= ("select id,mail,password user mail = '$username' , password = '$password'"); $result = mysqli_fetch_assoc($con->query($sqlstatement));  if (!$result) {     $response = array(         "status" => "f",         "message" => "benutzername und passwort stimmen nicht ueberein"     ); } else {     $response = array(         "status" => "t",         "message" => "erfolgreich eingeloggt!",         "data" => $result     ); } $con->close();  echo json_encode($response);?>

edit 1:

as use datatype: 'json' recieve nothing (not string), continue using 'text'. php file need change recieve json?

here things tried comments:

console.log(typeof d); returns string

alert(json.stringify(d)); returns "{\"status\":\"f\",\"message\":\"benutzername und passwort stimmen nicht ueberein\"}"

alert(json.parse(d)); returns uncaught syntaxerror: unexpected token in json @ position 0

any more recommendations? thank you!

try this

$.ajax({     url: 'http://localhost/weltenbummler/weltenbummler1/weltenbummler1/app/login.php?username=' + name + '&password=' + pass,     datatype: 'json',     type: 'get',     success: function (e) {         alert( json.parse(e.message) ); // undefined     } });

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...
