Make a curl request to a url having no file extension?
I have following URL
http://www.davesinclairstpeters.com/auto2_inventorylist?i=37647&c=12452&npg=1&ns=50&echo=2
I want to retrieve content of this url using curl but everytime I make this request it is showing me error, as it is not passing required parameters
Below is my code
$ch = curl_init(); // start CURL
curl_setopt($ch, CURLOPT_URL, $json_url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPGET, true);
curl_setopt($ch, CURLOPT_FRESH_CONNECT, true);
$response = curl_exec($ch);
That page doesn't give any information stating that the information isn't being passed properly. In fact, it tells you that the information has been recieved - by viewing the source, you can see:
<!--
javax.servlet.forward.request_uri = /auto2_inventorylist
...
javax.servlet.forward.servlet_path = /auto2_inventorylist
...
javax.servlet.forward.query_string = i=37647&c=12452&npg=1&ns=50&echo=2
-->
Which tells you the information has infact been recieved.
Therefore, it's no problem with your code, but with the website itself. You should make sure the URL you are using is valid, or contact that website to get more information.
With regards to your code itself - the curl_setopt($ch, CURLOPT_HTTPGET, true); isn't necessary, as this is already set by default, and you can also pass the URL as an argument of the curl_init function. Doesn't impact performance, but makes for neater code.
$ch = curl_init($json_url); // start CURL
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_FRESH_CONNECT, true);
$response = curl_exec($ch);
You code is perfectly fine and if there's something wrong returned, simply paste this URL to your web browser and check the result. In this case website simply failed for some reasons. There's nothing you can do about that as problem is NOT on your side.
This URL yields a page of cars with links to more cars. Looks like the URL you're starting with is old, or has some sort of expiration factor that's not obvious.
Not knowing which sort of filtering parameters you're shooting for.. hard to say what else my be wrong, other than your starting URL be bad.
working url:
