使用cURL对tomcat localhost进行PHP请求并获取响应

I'm new to PHP and am currently struggling to set this up. Could someone provide me an outline of how you use curl to post and retrieve the returning data?

I tried this out:

$url = 'http://localhost:8080/ds/stuff?maybe=false';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, $string);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$response = curl_exec($ch);
curl_close($ch);

But I keep getting the HTTP status 405 Error (aka this):

Am I doing something wrong/what should I do? Or do I have to change something in my ds/stuff

You should set CURLOPT_POST to true. POST data goes to CURLOPT_POSTFIELDS.

$url = 'http://localhost:8080/ds/stuff?maybe=false';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $string);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$response = curl_exec($ch);
curl_close($ch);
