Google服务器在隐私浏览模式下发出第一个请求时出现服务器错误

Question

每当我在Safari和Google Chrome的私人窗口中运行网址https://scholar.google.com/citations?user=N7m4vIQAAAAJ&hl=en时，Google都会出错。

它仅在具有隐私浏览模式的第一个请求中发生。

有谁知道为什么只在特定的环境中发生这种情况？ 自3天前以来一直在发生这种情况。

修复了在请求网址时使用Cookie的问题。 REF： PHP cURL如何添加用户代理值或克服服务器阻塞cURL请求？

我使用PHP脚本来检索并添加一些cookie选项。

代码片段是

    $curl = curl_init($url);
    $dir                   = dirname(__FILE__);
    $config['cookie_file'] = $dir . '/cookies/' . md5($_SERVER['REMOTE_ADDR']) . '.txt';

    curl_setopt($curl, CURLOPT_COOKIEFILE, $config['cookie_file']);
    curl_setopt($curl, CURLOPT_COOKIEJAR, $config['cookie_file']);

    curl_setopt($curl, CURLOPT_FOLLOWLOCATION, true);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);

    $data = curl_exec($curl);
    curl_close($curl);
