使用udemy api获取课程列表

问题描述

我正尝试使用其会员API和PHP来访问udemy课程列表。

如果不使用json_decode，我可以毫无问题地获取数据。 当我使用json_decode我收到此错误。

'SyntaxError：JSON.parse：JSON数据第1行第1列的意外字符'

function getcourse($id)
{
    header('Content-Type: application/json');

    $url = "https://www.udemy.com/api-2.0/courses/$id?fields[course]=@all";
    //  Initiate curl
    $ch = curl_init();
    // Disable SSL verification
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    // Will return the response, if false it print the response
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    // Set the url
    curl_setopt($ch, CURLOPT_URL,$url);
    // Execute
    $c_id = base64_encode('myclientid');
    $c_sid = base64_encode('myclientsecretid');

    curl_setopt($ch,CURLOPT_HTTPHEADER,array('X-Udemy-Client-Id: '.$c_id.'','X-Udemy-Client-Secret: '.$c_sid.'',"Authorization: base64 encoded value of client-id:client-secret","Accept: application/json, text/plain, */*"));
    curl_setopt($ch, CURLINFO_HEADER_OUT, true);
    $result=curl_exec($ch);
    echo curl_getinfo($ch, CURLINFO_HEADER_OUT);
    echo curl_getinfo($ch,CURLINFO_HTTP_CODE);
    // Closing
    curl_close($ch);


    $result = json_decode($result);
    return $result; 
}


$cdetail = getcourse(120042);
print_r($cdetail);
