I want to call a certain URL in my PHP script and if I do not get a response after 10s, the script should just continue. Does anyone knows how I can do that?
I only found two ways. One is fopen(), which determinates my script if it doesn't get a return and curl which is just calling the URL without waiting/getting response?
But how can I say, try to get the content of the URL and if you do not get anything after 10s then continue and ignore the URL?
You can use curl.
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "url");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_TIMEOUT, 10);
$response = curl_exec($ch);
curl_close($ch);
If timeout is occurred - $response variable has boolean 'false' value.

$url = "http://www.reddit.com/r/{mysubreddit}/new.json";
$fields = "sort=new";
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $fields);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$data = curl_exec($ch);
curl_close($ch);
var_dump($data);
{mysubreddit} is whatever subreddit I wanna check. It works fine to just grab that url via postman, or even in the browser. But when I use PHP/CURL, it returns empty. I've tried replacing the URL, with another URL to another site, and it works fine, so the curl part is working fine.
Is there something with reddit that I have to set? headers? or explicitly tell it for JSON? Or what?
I thought it might have to do with POST, but I tried GET to, still empty/null.
$url = "http://www.reddit.com/r/{mysubreddit}/new.json?sort=new";
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$data = curl_exec($ch);
curl_close($ch);
That doesnt work either
You just need to add:
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
As others have mentioned, reddit is sending you a 302 redirect to https. You would be able to see that by examining the headers returned by curl_getinfo().
Enabling redirect following, as sorak describes, will work. However, it's not a good solution - you will make two HTTP requests on every single API call. This is a completely unnecessary waste of network and increases the execution time of your script. Instead, just change the url that you're requesting to be from https://www.reddit.com/ in the first place.
I am using curl request to hit the has-offers conversion url from my sevrver with the help of curl but it is not working.But when I call the same URL using a browser, it works.Is they can block CURL requests?.I am not getting why, is there any port blocking issue.
Below is php code to call url using curl request.
<?php
function curl_get_contents($url)
{
$ch = curl_init();
$timeout = 5;
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
$data = curl_exec($ch);
curl_close($ch);
return $data;
}
$url="http://paravey.go2cloud.org/aff_l?offer_id=12&aff_id=1000";
$contents = curl_get_contents($url);
echo $contents;
?>
Please help me thanks in Advance
The url you are curling is a pixel tracking url:
http://paravey.go2cloud.org/aff_l?offer_id=12&aff_id=1000
The aff_l endpoint looks for a cookie with session information (hence why it works in the browser).
If you want to create conversions with server side code, you will need to store the session identifier (the transaction_id) in your system and use the aff_lsr endpoint to send that data to HasOffers to trigger a conversion.
The url for this would look like this:
http://paravey.go2cloud.org/aff_lsr?transaction_id= VALUE
Where Value is the session identifier you have stored.
I would ask the HasOffers support team if you have more issues with this.
EDIT: The proper thing to do is just to send a response from Node-red as hardillb pointed out below.
My CURL request is working fine and instantly, but I simply need to have the page visit the url and not wait around for a response. I have tried every combination I can think of and my browser still sits waiting for a server response until timeout.
$url = 'http://example.com:1880/get?temperature='.$temperature;
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT_MS, 1);
curl_setopt($ch, CURLOPT_NOBODY, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HEADER, 0);
// 3. execute and fetch the resulting HTML output
$output = curl_exec($ch);
// 4. free up the curl handle
curl_close($ch);
}
As mentioned in the comments.
The correct solution is to ensure your http-in node is paired with a http-response node in your Node-RED flow
I'm trying to fetch this url via a script: http://api.alarabiya.net/sections/2/
But JSON response received is much smaller than when I open it directly in a browser,
please notice that I tried this url through CURL and set the same USER-AGENT of the browser and all request header used in the browser and I still get a smaller response.
Here's an exmaple using just file_get_contents
<?php
echo file_get_contents("http://api.alarabiya.net/sections/2/");
?>
My question is if there's a request size limit when using file_get_contents or if the PHP's memory can't handle it or what's the problem exactly?
When I CURLed this in shell it gave me the same o/p as in php (the trimmed output).
I finally found a solution for this:
$url = "http://api.alarabiya.net/sections/2/";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true );
// This is what solved the issue (Accepting gzip encoding)
curl_setopt($ch, CURLOPT_ENCODING, "gzip,deflate");
$response = curl_exec($ch);
curl_close($ch);
echo $response;
I use the following command in some old scripts:
curl -Lk "https:www.example.com/stuff/api.php?"
I then record the header into a variable and make comparisons and so forth. What I would really like to do is convert the process to PHP. I have enabled curl, openssl, and believe I have everything ready.
What I cannot seem to find is a handy translation to convert that command line syntax to the equivalent commands in PHP.
I suspect something in the order of :
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
// What goes here so that I just get the Location and nothing else?
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
// Get the response and close the channel.
$response = curl_exec($ch);
curl_close($ch);
The goal being $response = the data from the api “OK=1&ect”
Thank you
I'm a little confused by your comment:
// What goes here so that I just get the Location and nothing else?
Anyway, if you want to obtain the response body from the remote server, use:
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$response = curl_exec($ch);
If you want to get the headers in the response (i.e.: what your comment might be referring to):
curl_setopt($ch, CURLOPT_HEADER, 1);
If your problem is that there is a redirection between the initial call and the response, use:
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
