Instagram API无效

Question

来自Instagram的结果Api几天前工作但现在当我试图从userid

获取username时显示错误

使用以下php代码

<?php
    $client = '84e9fefb6d8745059ab5290f68c1237f';
    $url = 'https://api.instagram.com/v1/users/search?q=vijaydohare&client_id='.$client;
    $ch = curl_init();
    curl_setopt_array($ch, array(
        CURLOPT_URL => $url,
        CURLOPT_RETURNTRANSFER => true,
        CURLOPT_SSL_VERIFYPEER => false,
        CURLOPT_SSL_VERIFYHOST => 2
    ));

    $result = curl_exec($ch);
    curl_close($ch);
    echo $result;
?>

我得到的回应

    "meta": {
        "error_type": "OAuthAccessTokenException",
        "code": 400,
        "error_message": "The access_token provided is invalid."
    }
}
