The below php code is making a REST API call that returns json object. This works fine when i use it on my localhost using WAMP Absolutely no problem.
However when i push this app on the server it would TimeOut and display 503 Service Unavailable.
I checked the logs it has an entry :
The TimeOut Specified has expired.
I contacted my admin he just said this app listens to PORT=64665 and HOST=0.0.0.0. What does that mean? What more changes do i need to make in my code to make it work on the server ? Help
<?php
$url = "http://xyz.net/v2/plan/"; // I have changed the REST URI API Link for security reasons
$ch = curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_PROXY, false);
curl_setopt($ch, CURLOPT_URL,$url);
$result=curl_exec($ch);
curl_close($ch);
// Will dump json
var_dump(json_decode($result, true));
$response = "http://xyz.net/v2/plan/";
echo $response;
?>
Check your server's /etc/hosts file, there could be the problem, ie. domain mapped to another (wrong) IP address.

I have two servers, one is my webserver, for my website, and the other one is my discord bot hosting server. My setup is when a certain action occurs on the webpage, it'll use cURL to post to the node.js server (the discord bot), which would then return some data.When it was in development and I was creating it on my localhost, it worked perfect (both servers were locally hosted). When I take the servers and run them on their respective services, I am given a connection refused error from cURL, same with file_get_contents().
$ch = curl_init();
curl_setopt($ch, CURLOPT_AUTOREFERER, TRUE);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_URL, 'http://51.161.93.27:8109/');
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
$data = curl_exec($ch);
echo "<pre>";
var_dump( curl_getinfo($ch) ) . '<br/>';
echo curl_errno($ch) . '<br/>';
echo curl_error($ch) . '<br/>';
curl_close($ch);
If I run this exact code from localhost instead of the webserver, it works and gets the data. On the webserver I can not post or get.
On the webserver, if I remove the port from the CURLOPT_URL, it'll connect to the main ip and return stuff. Same if I put www.google.com. This means cURL works, just can't connect to the port itself.
Note, the specific port is being run with the node.js http module along with express.
The webserver is being run from namecheap, and using cpanel. The discord bot hosting service is called pebblehosting.
Feel free to use the address, http://51.161.93.27:8109/ to find some more information, its the bot address. If able to succesfully get data from it, it should display a json string with a message stating {"status":"fail. You already have a ticket open"}.
I also connected to the address from services like ping.com and was able to connect.
I have spent all day trying to find a solution, but couldn't find anything.
I have been using cURL code to access Beanstream for awhile now, and all of a sudden it stopped working as of yesterday. I have determined that this has to do with accessing the HTTPS URL for Beanstream processing, as if I test that same code and just go to the HTTP URL, it works (of course it returns an insecure connection code).
Prior to the below code I was setting VERIFYPEER / VERIFYHOST to FALSE, which was working up until yesterday.
$url = 'https://www.google.com';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 30);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);
curl_setopt($ch, CURLOPT_CAINFO, "/xxxx/public_html/_cert/GeoTrustGlobalCA_google.crt");
$getResponse = (curl_exec($ch));
curl_close($ch);
print_r($getResponse);
I have setup the above test code to try and access Google via HTTPS. I had read that a proper connection requires the VERIFYPEER / CAINFO options to be set, which I have done and grabbed the Google .crt and placed it on the web server as well.
I still get a 503 Service Unavailable error back though.
The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.
Additionally, a 503 Service Unavailable error was encountered while
trying to use an ErrorDocument to handle the request.
As recommended by my DocuSign account manager, I am using Fiddler2 to capture the necessary trace for API certification. I am unable to retrieve the trace from the DocuSign domain and have narrowed it down to the fact that these are cURL calls.
According to Fiddler2, http://fiddler2.com/documentation/Configure-Fiddler/Tasks/ConfigurePHPcURL, the advice is to add the following to code:
curl_setopt($ch, CURLOPT_PROXY, '127.0.0.1:8888');
where $ch = curl_init().
I've also tried
curl_setopt($curl, CURLOPT_PROXY, '127.0.0.1:8888');
Still no dice. I only get traffic from my application site. The following is all of my curl code:
$url = "https://demo.docusign.net/restapi/v2/login_information";
$curl = curl_init($url);
$ch = curl_init();
curl_setopt($curl, CURLOPT_HEADER, false);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_HTTPHEADER, array("X-DocuSign-Authentication: $header"));
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, true);
curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, 2);
curl_setopt($curl, CURLOPT_CAINFO, getcwd() ."/**the cert info");
curl_setopt($ch, CURLOPT_PROXY, '127.0.0.1:8888');//allows fiddler to see requests
$json_response = curl_exec($curl);
$status = curl_getinfo($curl, CURLINFO_HTTP_CODE);
It's definitely talking to the DocuSign domain as my application is working, I'm just trying to get the trace. Any help is appreciated.
fiddler is client side program, it cannot see server traffic to other servers only traffic between client and server.
Unless your server is running locally (on the same computer that you are running fiddler) using 127.0.0.1 this will not work as 127.0.0.1 is the loopback ip for the computer, in this case the server would be trying to use itself as a proxy (which would be ok if the server computer itself was the one running fiddler). You need to change the ip to the computer running fiddler and make sure the server can access that port.
I was facing the exact same scenario, and I used a protocol analyzer such as Wireshark or TCPDUMP to see HTTP traffic at network level.
Of course the server needs to be running locally. Bellow you can find a screenshot example of traffic capture where you can clearly see the HTTP GET going out.
Hi I have a server which has several virtual hosts set up on it.
I wanted to make a curl request to this server's ip using php.
Also I wanted to make this request to a specific hostname on the server's ip.
Is there a way to do it?
A bit more elaboration :
I want to make a curl requests between my servers using internal LAN, using their internal IP. The issue is that I have several sites hosted on this server. So when i make a curl request to the internal IP of the server.. something like (curl_init(xxx.xxx.xxx.xxx)), I want to be able to be tell apache to go to a particular folder pointed to by a virtual host. I hope that made the question a bit more clear.. – Vishesh Joshi 3 mins ago edit
You can set the host header in the curl request:
<?php
$ch = curl_init('XXX.XXX.XXX.XXX');
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Host: subdomain.hostname.com'));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
echo curl_exec($ch);
For HTTPS sites use CURLOPT_RESOLVE which exists in every PHP version since PHP 5.5.
<?php
$ch = curl_init('https://www.example.com/');
// note: array used here
curl_setopt($ch, CURLOPT_RESOLVE, array(
"www.example.com:443:172.16.1.1",
));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_VERBOSE, true);
$result = curl_exec($ch);
Sample output:
* Added www.example.com:443:172.16.1.1 to DNS cache
* Hostname www.example.com was found in DNS cache
* Trying 172.16.1.1...
Base on Leigh Simpson,
It works, but I need query string attach with it.
That's what I work around:
<?php
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://xxx.xxx.xxx.xxx/index.php?page=api&action=getdifficulty");
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Host: subdomain.hostname.com'));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
echo curl_exec($ch);
?>
