现在，我登录到一个网站，该网站在标题中显示我的用户名，表明我已登录。

现在，当我尝试抓取该网页并在我的 m/c 上显示结果时，页面标题显示“登录”，表明我需要登录。

我想我在抓取时遗漏了一些我需要考虑的 cookie 信息。

有什么办法我也可以读取cookies。

卷曲代码：

function getString( $url ) {
    $ch = curl_init();
    curl_setopt( $ch, CURLOPT_URL, $url );
    curl_setopt( $ch, CURLOPT_RETURNTRANSFER, 1 );
    curl_setopt( $ch, CURLOPT_AUTOREFERER, true );
    curl_setopt( $ch, CURLOPT_COOKIESESSION, true );
    curl_setopt( $ch, CURLOPT_COOKIEJAR, 'cookie.txt' );
    $response = curl_exec( $ch );
    curl_close( $ch );
    return $response;
}

由于完整路径 Cookie 路径，您的代码无法正常工作，并确保它cookie.txt是可写的

尝试

var_dump(getString("http://google.com"));

    function getString($url) {
    $ch = curl_init();
    $cookie =  __DIR__ . '/cookie.txt' ;
    touch($cookie);

    if(!is_writable($cookie))
    {
        die("Can't write to cookie");
    }

    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_AUTOREFERER, true);
    curl_setopt($ch, CURLOPT_COOKIESESSION, true);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
    curl_setopt($ch, CURLOPT_COOKIEJAR,$cookie);
    curl_setopt($ch, CURLOPT_COOKIEFILE,$cookie);
    $response = curl_exec($ch);
    curl_close($ch);
    return $response;
}

cookie.txt 输出
