Google云端硬盘api上传失败

Question

我想将一个文件从网址上传到google drive，但我收到了错误消息。我用本地文件测试了它，它的工作原理。这有什么问题？

这是我的代码：

<?php
require_once __DIR__ . '/vendor/autoload.php';
require_once __DIR__ . '/GoogleApi.php';

if (php_sapi_name() != 'cli') {
    throw new Exception('This application must be run on the command line.');
}

 *
 * @param resource $handle
 * @param int      $chunkSize
 *
 * @return string
 */
function readFileChunk($handle, int $chunkSize) {
    $byteCount = 0;
    $giantChunk = '';
    while (!feof($handle)) {
        $chunk = fread($handle, 8192);
        $byteCount += strlen($chunk);
        $giantChunk .= $chunk;
        if ($byteCount >= $chunkSize) {

            return $giantChunk;
        }
    }

    return $giantChunk;
}

    # Get all header information
    $data = get_headers($url, true);
    # Look up validity
    if (isset($data['Content-Length'])) {
        return (int) $data['Content-Length'];
    }

    return 0;
}

/**

 *
 * @param string $url
 *
 * @return string
 */
function remoteMimeType($url) {
    $ext = pathinfo($url, PATHINFO_EXTENSION);
    $mimeType = 'application/octetstream';

    switch ($ext) {
        case 'zip'    :
            $mimeType = 'application/zip';
            break;
        case 'rar'    :
            $mimeType = 'application/x-rar-compressed';
            break;
        case '7z'    :
            $mimeType = 'application/x-7z-compressed';
            break;
    }

    return $mimeType;
}
