Hello,

It works with body as a third parameter. Body has to be defined in http request because without that third parameter is ignored.

Working example:

for $x in http:send-request(
  <http:request method='post'>
    <http:header name="User-Agent" value="Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/67.0.3396.99 Safari/537.36"/>
    <http:body media-type='application/x-www-form-urlencoded; charset=UTF-8'/>
  </http:request> 
,'http:localhost:3333', 'start=0&amp;length=100&amp; ')[2]/data/results/content
return $x

Thank you Christian for help.

Best Regards
Bogdan Bogucki

Hi Bogdan,

I didn’t try it, but what happens if you specify the body as third argument?

Cheers,
Christian
