получать данные из JSON в Jquery

Question

у меня есть этот PHP файл, который получит данные пользователя из Instagram API

<?php 

//Get data from instagram api 

$keyword = $_GET['keyword']; 

if(!isset($_GET['count'])) $count = 20; 

else $count = $_GET['count']; 


//Query need client_id or access_token 

$query = array(
    'client_id' => '8c81a425a76340a79aa66cb88aa74c89', 
    'count'  => $count 
); 

$url = 'https://api.instagram.com/v1/users/search?q='.$keyword.'&'.http_build_query($query); 


try { 
    $curl_connection = curl_init($url); 
    curl_setopt($curl_connection, CURLOPT_CONNECTTIMEOUT, 30); 
    curl_setopt($curl_connection, CURLOPT_RETURNTRANSFER, true); 
    curl_setopt($curl_connection, CURLOPT_SSL_VERIFYPEER, false); 

    //Data are stored in $data 
    $data = curl_exec($curl_connection); 
    curl_close($curl_connection); 
    echo $data; 

} catch(Exception $e) { 
    return $e->getMessage(); 
} 

?> 

и вернуть JSON строку с информацией 20 пользователя как

я просто хочу, чтобы использовать username и profile_picture из retrived данных и отображать его в тегах ..

но ничего отображается я не знаю, почему .. может кто-нибудь помочь, пожалуйста?

Answer 1

Вы можете удалить строку с JSON.parse() как уже явно установлено, что вы получите JSON:

dataType: 'JSON', 

Затем в блоке успеха, обрабатывать его следующим образом:

$.each(jsonStr.data, function(index, element){ 
    $("#result").text(element.username); 
    $("#img").attr('src', element.profile_picture); 
});
