Question

当我从浏览器调用Slim php中的路由时，它运行得很好，但是当我通过Ajax调用它时，我收到了404错误。有问题的函数发出Curl请求。我怀疑这可能与我用curl发送的标题有关：

$data = $this->curl->call($url, $urlParams, $postParams, $method, $this->getDefaultHeaders());

protected function getDefaultHeaders() {
		
        return array(
            'Authorization' => 'Bearer ' . $this->access_token,
            'Accept' => self::HTTP_HEADER_ACCEPT,
        );
    }

class Curl {

    const METHOD_GET = 'GET';
    const METHOD_POST = 'POST';
    const METHOD_PUT = 'PUT';
    const METHOD_DELETE = 'DELETE';
    
    const CURL_TIMEOUT_IN_SECS = 15;

    public static $successFullHttpCodes = array(200, 201, 204);

    public function call($url, $urlParams = array(), $postParams = null, $method = self::METHOD_GET, $headers = array()) {
        $finalUrl = $url . $this->getUrlParameterString($urlParams);
        $data = $this->makeCurlCall($finalUrl, $postParams, $method, $headers);
        return $data;
    }

            curl_setopt($curl, CURLOPT_HTTPHEADER, $usableHeaders);
        }

事实证明我的错误是在引发两个不同的会话时将api令牌存储在会话变量中。
