Question

我正在尝试通过URL从ServiceNow启动自动下载CSV文件的操作。

我可以将链接"https://<mycompany>.service-now.com/incident_list.do?CSV&sysparm_query=sys_updated_onBETWEENjavascript:gs.daysAgoStart(0)@javascript:gs.daysAgoEnd(0)&sysparm_orderby=sys_updated_on"粘贴到浏览器中，然后自动下载CSV文件。我想使它自动化。我尝试使用javascript，但没有绕过相同原产地政策。我正在尝试使用以下代码编写PHP CURL。

<?php

include 'credentials.php';

function get_web_page( $url)
{
$header = array('content-type: application/x-www-form-urlencoded');
 global $user;
 global $pass;

    $options = array(
        CURLOPT_CUSTOMREQUEST  => 'GET',
        CURLOPT_RETURNTRANSFER => true,     // return web page
        CURLOPT_HEADER         => false,    // don't return headers
        CURLOPT_FOLLOWLOCATION => true,     // follow redirects
        CURLOPT_ENCODING       => "",       // handle all encodings
        CURLOPT_USERAGENT      => "spider", // who am i
        CURLOPT_AUTOREFERER    => true,     // set referer on redirect
        CURLOPT_CONNECTTIMEOUT => 120,      // timeout on connect
        CURLOPT_TIMEOUT        => 120,      // timeout on response
        CURLOPT_MAXREDIRS      => 10,       // stop after 10 redirects
        CURLOPT_SSL_VERIFYPEER => false,     // Disabled SSL Cert checks
        CURLOPT_HTTPHEADER     => array('content-type: application/x-www-form-urlencoded'),
        CURLOPT_USERPWD        => "$user:$pass"

    );

    $ch      = curl_init( $url );
    curl_setopt_array( $ch, $options );
    $content = curl_exec( $ch );
    $err     = curl_errno( $ch );
    $errmsg  = curl_error( $ch );
    $header  = curl_getinfo( $ch );
    curl_close( $ch );

$header['errno']   = $err;
$header['errmsg']  = $errmsg;
$header['content'] = $content;
return $header;
}
$Content_Array = array();

$url = 'https://<mycompany>.service-now.com/incident_list.do?CSV&sysparm_query=sys_updated_onBETWEENjavascript:gs.daysAgoStart(0)@javascript:gs.daysAgoEnd(0)&sysparm_orderby=sys_updated_on';//
echo '<hr>'.$url.'<hr>';
$page =  get_web_page( $url );
echo $content = $page['content'];
echo '<pre>';
print_r($page);
echo '</pre>';
?>

这将返回一系列信息，但不是我需要的信息，并且不会下载任何内容。希望我只是缺少一些简单的东西。

在您指定输出文件的任何地方都看不到。您可以使用 CURLOPT_FILE 选项和 fopen 自动保存输出。这是我从here借来的精简示例：

$out = fopen($localfilename, 'wb');
$ch = curl_init();
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_FILE, $out);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_USERPWD, "username:password");
curl_exec($ch);
curl_close($ch);
fclose($out);
