php - Citrix PHP cURL oAuth 無効キー

Question

私はこれに問題があり、誰かが助けてくれるかどうかわかりません。これについて考えているoAuthキーの取得に問題があります。私が返し続けるエラーはinValidKeyであり、私は調査して調査しました。わからないだけかもしれませんが、これを固定することはできません。

<?php

class ApiClient {

    private $oauthToken;

    public function __construct($oauthToken) {
        $this->oauthToken = $oauthToken;
    }

    public function post($url, $data) {
        $data_string = json_encode($data);   

        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $url); 
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
        curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);

        curl_setopt($ch, CURLOPT_TIMEOUT, '10');

        $headers = array(
                "Content-Type: application/json",
                "Accept: application/json",
                "Authorization: OAuth oauth_token={$this->oauthToken}",
                "Content-Length: " . strlen($data_string)
            );
        curl_setopt($ch, CURLOPT_HTTPHEADER, $headers); 

        $ret = curl_exec($ch);

        return json_decode($ret);
    }

    public function get($url) {
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $url); 
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt($ch, CURLOPT_TIMEOUT, '10');

        $headers = array(
                "Content-Type: application/json",
                "Accept: application/json",
                "Authorization: OAuth oauth_token={$this->oauthToken}"
            );
        curl_setopt($ch, CURLOPT_HTTPHEADER, $headers); 

        $ret = curl_exec($ch);

        return json_decode($ret);
    }

}

        }
        $this->developerKey = $this->apps[$app]['developerKey'];
