Twilio - 下载的通话录音有时是空的

标签: download twilio recording conference

我目前正在努力解决一个问题,即少数录音是空的(当从Twilio的服务器下载时)它们不应该是。

我的申请目前每天约有10,000个电话。如果应答,则记录这些呼叫中的每一个,然后将该记录下载到我的服务器。

无论出于何种原因,这些下载的mp3文件中的少数是空的,它们的大小为363字节(没有音频,只有文件本身),即使我知道mp3文件中应该有内容。例如,某些通话将持续30-40分钟,但下载时会录制空白。

我正在使用PHP开发并附加了用于下载下面录制的代码。有什么看起来偶尔会引起问题吗?我已经尝试过寻找其他人可能遇到的类似问题,到目前为止还没找到任何东西。

请记住,此代码适用于90%的情况......只有10%的代码无法正确下载。

非常感谢你的时间!

public function index()
{
    if (isset($_REQUEST['RecordingUrl'])) {

        // Get the call ID from the url
        $confId = $this->security->xss_clean($_GET['confId']);
        $callId = $this->security->xss_clean($_GET['callId']);
        $userId = $this->security->xss_clean($_GET['userId']);

        // Twilio account information
        $accountSid = $this->config->item('twilio_accountSid');
        $authToken  = $this->config->item('twilio_authToken');

        // Download the recording to our server
        $callUrl = 'recordings/calls/' . $callId . '.mp3';
        $this->getMp3($_REQUEST['RecordingUrl'], $callUrl);

        // Delete the recording from Twilio's servers
        $this->deleteMp3($_REQUEST['RecordingUrl'], $accountSid, $authToken);

        // Mark this call as completed and update its log
        $this->call->logEndOfCall($callId);

        // Load a blank Twilio response to keep the server from throwing an error
        $this->load->view('twilio/blank_twiml');
    }
}

private function getMp3($sourceUrl = '', $destinationUrl = '')
{
    // Add the '.mp3' onto the end of the url to return an mp3 file
    $sourceUrl = $sourceUrl . '.mp3';

    // Set the variables and initialize cURL
    $destinationUrl = '/' . $destinationUrl;
    $fp = fopen($destinationUrl, 'w+');
    $ch = curl_init();
    $timeout = 300;

    // Sleep for two seconds to prevent a race condition with Twilio
    sleep(2);

    // Set the options for cURL to download the file
    curl_setopt($ch, CURLINFO_HEADER_OUT, TRUE);
    curl_setopt($ch, CURLOPT_HEADER, FALSE);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
    curl_setopt($ch, CURLOPT_URL, $sourceUrl);
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
    curl_setopt($ch, CURLOPT_FILE, $fp);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);

    // Execute the cURL
    curl_exec($ch);

    // Save any information for future debugging purposes
    $info = curl_getinfo($ch);

    // Close the new mp3 file and cURL
    curl_close($ch);
    fclose($fp);
}

private function deleteMp3($url = '', $username, $password)
{
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'DELETE');
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_HEADER, 1);
    curl_setopt($ch, CURLOPT_USERPWD, $username . ":" . $password);
    $result = curl_exec($ch);
    curl_close($ch);
}

我无法在他们的网站上收到Twilio的回复,而且我自己的搜索没有显示任何结果。

我现在所做的就是实现一个循环,它会多次调用getMp3,直到确认文件已正确下载为止。我是使用PHP的文件大小功能完成的。
