I'm new to using and API in php.
I have an existing call to an external API, which works and looks like this:
// $id = "227";
// $url = "external-api.com/places/$id?;
// url above works, too
$url = "external-api.com";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
curl_setopt($ch, CURLOPT_USERPWD, "$partner_code:$secret_code");
$result = curl_exec($ch);
curl_close($ch);
echo($result);
On my local server the page is displayed correctly when I enter http://localhost/mytest/mytest.php
The page also displays links and when I click on of them, it shows me the page could not be found. This is because the target is localhost/places/227 and there is no such page.
What I want now is that a call to localhost/places/227 shows a result of an API call to external-api.com/places/227. Just like in the example above, except that this time $url has changed to external-api.com/places/227.
But this shouldn't happen to every link on my website. Just to those links that were retrieved by the API call.
So I think this is what I want: When the link to /places/227 is clicked I want the above php script to be executed again except that the varaible for $url has changed to $url = "external-api.com/places/227;

I am trying to fetch data from a URL using cURL...this is something I would be able to do but the URL that I want to fetch data from has a section of php code within it - i.e. the URL is populated using a values generated by an earlier section of code.
I want to access the URL, take the figures out of it and then plug those figures into something else. At the minute I am hitting a bit of a roadblock as the php doesn't populate the URL...any ideas?
The code I am using is:
$url = "https://*START OF API ADDRESS*<?php echo $request_ids; ?>*END OF API ADDRESS*";
$ch = curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_URL,$url);
$result=curl_exec($ch);
curl_close($ch);
//var_dump(json_decode($result, true));
$rates = json_decode($result, true);
// Save result
$rates['last_updated'] = time();
file_put_contents($file, json_encode($rates));
}
I try to get odata produced by a navision webservice. When I directly access the url given using chrome browser, the page asks for user name and password and then chrome shows xml data as expected.
But when i use a PHP script, it always returns "1".
My code looks like this:
$url = 'http://103.7.1.182:14048/DynamicsNAV71-6/OData/Company(\'Unit%20G%205\')/Item_Master_on_hand_no_Desc';
$login = 'Gem-gae\senzo1:Bsbsenzo2018';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_USERPWD, $login);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Content-Type:application/x-www-form-urlencoded',
'Content-Length: ' . strlen(1))
);
$output = curl_exec($ch);
curl_close($ch);
echo $output;
Is there any mistakes with that code ?
Thanks for your help
There's no mistake on your code, it successfully connects to the external server via cURL and retrieves the data.
The value in $output (if you do a var_dump) is true (that's why you see 1 if you echo it).
Said that, the issue is on the server you are contacting (103.7.1.182:14048).
You probably need to send some data or something, I can't tell you exactly what because I don't know what is in that server.
To send data, you can add a curl_setopt line:
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($data));
Where $data is an array.
Following is the call to an URL using CURL :
<?php
ini_set('display_startup_errors',1);
ini_set('display_errors',1);
error_reporting(-1);
$link = $_GET['link'];
$url = "http://www.complexknot.com/user/verify/link_".$link."/";
// create a new cURL resource
$ch = curl_init();
// set URL and other appropriate options
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, 0);
// grab URL and pass it to the browser
curl_exec($ch);
// close cURL resource, and free up system resources
curl_close($ch);
?>
The variable $url contains one URL which I'm hitting using CURL.
The logic written in the file(present in a variable $url) is working absolutely fine.
After executing the code I want the control to be redirected to one URL. For it I've written following code :
header('Location: http://www.complexknot.com/login.php');
exit;
The following code is not working. The URL http://www.complexknot.com/login.php is not opening and a blank white page appears. This is the issue I'm facing.
If I don't use the CURL and hit the URL i.e. the URL contained in $url then it gets redirect to the URL http://www.complexknot.com/login.php that means header function works fine when I hit the URL in browser.
Why it's not working when I call it from CURL?
Please someone help me.
Thanks in advance.
This is happening because CURL is outputting the data. You must use curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); in order to let CURL returning data instead of outputting it.
<?php
ini_set('display_startup_errors', 0);
ini_set('display_errors', 0);
error_reporting(0);
$link = $_GET['link'];
$url = "http://www.complexknot.com/user/verify/link_$link/";
// create a new cURL resource
$ch = curl_init();
// set URL and other appropriate options
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// grab URL and pass it to the browser
curl_exec($ch);
// close cURL resource, and free up system resources
curl_close($ch);
header('Location: http://www.complexknot.com/login.php');
You can use
<?php echo "<script>window.location.href = 'http://www.complexknot.com/login.php';</script>";die; ?>
trying to send post request to api, to get an image back.
example url:
https://providers.cloudsoftphone.com/lib/prettyqr/createQR.php?user=1003123&format=png&cloudid=asdasdasd&pass=123123123
the above url works fine in the browser,
the api doesnt care if the request is get/post,
result of my code is always 'invalid input'.
code:
$url='https://providers.cloudsoftphone.com/lib/prettyqr/createQR.php';
$u = rand();
$p = rand();
$fields = array(
'user'=> urlencode($u),
'pass'=> urlencode($p),
'format'=> urlencode('jpg'),
'cloudid' => urlencode('test')
);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $fields);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
$output = curl_exec($ch);
curl_close($ch);
echo $output;
on a side note: is there a way to debug the request in order to see what is being sent ?
The URL provided isn't working for POST request. Here is resulting screenshot (I tried using Advance Rest Client)
However Its working perfectly with GET method. So you can continue using GET request method to generate QR code.
I agree that GET isn't much secure compare to POST method but in your case while requesting from curl user won't get to know about such URL parameters (userid, password). Because curl request will be sending from your web server and not from client/user's browser.
Later you can just output the response image you got from the api.
I would like to fetch the content of the page from vk.com.I'm using php and i've got the page contents but however its not the appropriate contents.For example when i get the contents from vk.com/video56612186_167049188 is should be getting the video details completely at the bottom but i'm getting the users video list as page content.I've noted that that the the part that i want is loaded by ajax upon click and the link on the address bar also chnages, means that i should be getting the video contents but its not the case.
<?php
set_time_limit(0);
function get_content_of_url($url){
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_BINARYTRANSFER, true);
$content = curl_exec($ch);
curl_close($ch);
return $content;
}
$plyst = get_content_of_url("http://vk.com/video56612186_167049188");
?>
The URL is sending a redirect , so add this cURL param to your existing thing..
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
