Question

I need to get images from Google Chart, but I’m behind a proxy.

With the code below (changing $url) I can get images from other sites, but not from google:

$url =
‘http://chart.apis.google.com/chart?chs=450×270&chd=t:’.$values_list.’&cht=p&chl=’.$labels_list.’&chco=80AF1B,FFFF8C&chf=bg,s,F8F8F8′;

$img = '../uploads/tx_oriindicadores/triglo.png'; 

file_put_contents($img, t3lib_div::getURL($url));

The code of the getURL() method uses cURL functions to connect and retrieve data.

At this moment I only get an empty file.

Are there some parameters or configuraton that I care in order to get images from google?

Thanks.

The getURL() method is native of TYPO3 and you can see the code in this page:

I pass the parameters through the backend of the site.

Answer 1

The function above is right, the problem was that in the variable $labels_list there were spaces. So replacing the spaces with %20 solved the problem.

The spaces in the direct URL request are not a problem, but in cURL there are.

So as general rule don’t use spaces when work with cURL, use instead %20.
