我正在研究如何从某个特定项目中导出仪表板，例如显示此链接。
我制作的代码会像预期的那样正确生成下载链接。但是导出的 PDF 文件并没有像我想要的那样带来过滤的值。
我的问题发生在此评论下方：
// Execute the dashboard with context
...我想设置“影响仪表板的所有过滤器”，就像上面的链接所说的那样。但它没有指定如何设置过滤器的值。
我在 PHP 中编写了所有代码（替换所有“{some-thing}”以使此代码工作）：
<?php
$login = '{email}';
$pass = '{password}';
$headers = array('accept' => 'Accept: application/json','content-type' => 'Content-Type: application/json; charset=utf-8');
$data = json_encode(array('postUserLogin'=>array('login'=> $login,'password'=> $pass,'remember'=>0)));
$ch = curl_init();
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_URL, "https://secure.gooddata.com/gdc/account/login");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HEADER, 1);
$output = curl_exec($ch);
$AuthSST = substr($output, strrpos($output, "GDCAuthSST=")+strlen("GDCAuthSST="), 17);
$headers = array('accept' => 'Accept: application/json',
'content-type' => 'Content-Type: application/json; charset=utf-8',
'cookie:' => 'Cookie: $Version=0; GDCAuthSST='.$AuthSST.' $Path=/gdc/account');
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_HTTPGET, 1);
curl_setopt($ch, CURLOPT_URL, "https://secure.gooddata.com/gdc/account/token");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HEADER, 1);
$output = curl_exec($ch);
$start = strrpos($output, "GDCAuthTT=")+strlen("GDCAuthTT=");
$finish = strrpos($output, "Path=/gdc");
$GDCAuthTT = substr($output, $start, ($finish-$start));
$headers = array('accept' => 'Accept: application/json',
'content-type' => 'Content-Type: application/json; charset=utf-8',
'cookie:' => 'Cookie: $Version=0; GDCAuthTT='.$GDCAuthTT.' $Path=/gdc/account');
// Authentication finished, now start the dashboard export API
// Execute the dashboard with context
$project_id = '{project_id}';
$filter_id = '{filter_id}';
$filter_obj = '{0000}';
$dash_obj = '{0000}';
$url = 'https://secure.gooddata.com/gdc/internal/projects/'.$project_id.'/executionContexts';
// Inside filters: constraint, promptUri, uri, id ||||||||| Inside executionContext: dashboard, links, name, type, user
$bode = json_encode(array('executionContext' => array('filters' => array(array(
