我想从网站获取一些详细信息，我的代码在 wampserver 中运行良好，但是当我将文件上传到真实服务器上时，我没有得到任何结果，它向我显示了一个空白页面，这是我的代码。

    <?php 
error_reporting(E_ALL);

$htm = my_curl($url);
echo $htm;
$dat = file_get_contents('cookies.txt');

echo "<pre>";
echo PHP_EOL . "<b>$url</b>";
echo PHP_EOL . "<i>$dat</i>";
echo PHP_EOL;


function my_curl( $url, $timeout=5, $error_report=TRUE)
{
    $curl = curl_init();


    $header[] = "Accept: text/xml,application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5";
    $header[] = "Cache-Control: max-age=0";
    $header[] = "Connection: keep-alive";
    $header[] = "Keep-Alive: timeout=5, max=100";
    $header[] = "Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7";
    $header[] = "Accept-Language: en-us,en;q=0.5";
    $header[] = ""; // BROWSERS USUALLY LEAVE BLANK

    // SET THE CURL OPTIONS - SEE http://php.net/manual/en/function.curl-setopt.php
    curl_setopt( $curl, CURLOPT_URL,            $url  );
    curl_setopt( $curl, CURLOPT_USERAGENT,      'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1.6) Gecko/20091201 Firefox/3.5.6'  );
    curl_setopt( $curl, CURLOPT_HTTPHEADER,     $header  );
    curl_setopt( $curl, CURLOPT_REFERER,        'http://www.google.com'  );
    curl_setopt( $curl, CURLOPT_ENCODING,       'gzip,deflate'  );
    curl_setopt( $curl, CURLOPT_AUTOREFERER,    TRUE  );
    curl_setopt( $curl, CURLOPT_RETURNTRANSFER, TRUE  );
    curl_setopt( $curl, CURLOPT_FOLLOWLOCATION, TRUE  );
    curl_setopt( $curl, CURLOPT_COOKIEFILE,     'cookies.txt' );
    curl_setopt( $curl, CURLOPT_COOKIEJAR,      'cookies.txt' );
    curl_setopt( $curl, CURLOPT_TIMEOUT,        $timeout  );


    $htm = curl_exec($curl);

    // ON FAILURE HANDLE ERROR MESSAGE
    if ($htm === FALSE)
    {   echo 'HELO';
        if ($error_report)
        {echo 'HELOs';
            $err = curl_errno($curl);
            $inf = curl_getinfo($curl);
            echo "CURL FAIL: $url TIMEOUT=$timeout, CURL_ERRNO=$err";
            var_dump($inf);
        }
        curl_close($curl);
        return FALSE;
    }

    // ON SUCCESS RETURN XML / HTML STRING
    curl_close($curl);
    return $htm;
}

我检查了我的 php 配置，一切似乎都很好。我在 Stack Overflow 的任何其他相关帖子中都找不到任何答案。

错误：

CURL 失败：http : //14.139.236.46:7001/Forms/Student/PrintReportCard.aspx?rollno=11013001027&sem=07 TIMEOUT=5，CURL_ERRNO=7array(22) { ["url"]=> string(86) " http ://14.139.236.46:7001/Forms/Student/PrintReportCard.aspx?rollno=11013001027&sem=07" ["content_type"]=> NULL ["http_code"]=> int(0) ["header_size"]=> int(0) ["request_size"]=> int(0) ["filetime"]=> int (-1) ["ssl_verify_result"]=> int(0) ["redirect_count"]=> int(0) ["total_time"]=> float(0) ["namelookup_time"]=> float(0.001099) [" connect_time"]=> float(0) ["pretransfer_time"]=> float(0) ["size_upload"]=> float(0) ["size_download"]=> float(0) ["speed_download"]=> float (0) ["speed_upload"]=> float(0) ["download_content_length"]=> float(-1) ["upload_content_length"]=> float(-1) ["starttransfer_time"]=> float(0) [ "redirect_time"]=> float(0) ["certinfo"]=>数组（0）{}[“redirect_url”]=>字符串（0）“”}

我认为您的网址无效 - 目前您的网址类似于：

http://14.139.236.46:7001/Forms/Student/PrintReportCard.aspxrollno=123&sem=456

虽然我认为它应该是：

http://14.139.236.46:7001/Forms/Student/PrintReportCard.aspx?rollno=123&sem=456

添加 ? 在 aspx 和 rollno 之间再试一次

尝试单独设置端口。

curl_setopt($ch, CURLOPT_PORT, 7001);
