I have this code to POST data to an url that is receiving the data with below, with content-type header set as text/html
file_get_contents("php://input");
This is the code That I used to POST to url and it is sending the data, but without values (i'm sending an array data with key values).
$url = "http://url im sending data to";
$object = array(
"key1" => "123",
"key2" => "345",
"key3" => "567"
);
$data = http_build_query($object, '', '&');
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTREDIR, 3);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
$result = curl_exec($ch);
However, it's sending the data, but without the values, since I get a response back from the url saying that values are empty.
Moreover, I checked the curl_errno($ch) and it doesn't return anything so there is no error within my code (I think?)
Can someone help me out?!
Thanks in advance!
OK I solved the problem and it was pretty simple.
Just swap the http_build_query with json_encode, and make sure to only set the curl_setopt as it is.
add the bottom code also.
curl_setopt($ch, CURLOPT_TIMEOUT, 10);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 10);
I don't know why but for some reason, if I add other curl_setopt variables like
curl_setopt($ch, CURLOPT_POST, true);
it does not work.

I have rest API of Nodejs Server, I'm trying to make a POST call to it using PHP.
My php code is:
function post_url($apiRoute,$data) {
$request_url = 'http://test-app.herokuapp.com';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $request_url . $apiRoute);
curl_setopt($curl, CURLOPT_HTTPHEADER, array('Content-Type:application/json'));
curl_setopt($ch, CURLOPT_POST, 1);
echo $data ;
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
//curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$result = curl_exec($ch);
curl_close($ch);
return $result;
}
I have tried calling this function with diff forms of data:
$g = array("_id" => "111");
$postapiresponse = post_url('/CCTRequest/get',json_encode($g));
OR
$postapiresponse = post_url('/CCTRequest/get',json_encode(array("_id" => "111"));
But on server side which Node.js, when I console log req.body I get data like this:
{ '{"_id":"111"}': '' }
How should I pass the data in PHP so I can get proper obj in node.js i.e:
{ '_id': '111' }
See the PHP document:
http://php.net/manual/en/function.curl-setopt.php
CURLOPT_POST:
TRUE to do a regular HTTP POST. This POST is the normal
application/x-www-form-urlencoded kind, most commonly used by HTML forms.
CURLOPT_POSTFIELDS:
If value is an array, the Content-Type header will be set to multipart/form-data.
So you can pass a query string returned by http_build_query() into CURLOPT_POSTFIELDS:
post_url('/CCTRequest/get', http_build_query($g, null, '&'));
and remove curl_setopt($curl, CURLOPT_HTTPHEADER, array('Content-Type:application/json'));. (In fact, the varieble should be $ch, but you typed $curl, so this line doesn't work.)
In the other way, you can replace curl_setopt($ch, CURLOPT_POST, 1); with
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'POST');, it can prevent the data be encoded automaticlly. And then send json_encode() data.
I have solved by using http_build_query($g, null, '&') for making data.
$g = array("_id" => "111");
$g = http_build_query($g, null, '&');
$postapiresponse = post_url('/CCTRequest/get', $g);
You have a typo in the code, which will prevent it setting the header $curl should be $ch:
curl_setopt($curl, CURLOPT_HTTPHEADER, array('Content-Type:application/json'));
You also need CURLOPT_RETURNTRANSFER uncommented.
function post_url($apiRoute, $data) {
$request_url = 'www.example.com';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $request_url . $apiRoute);
curl_setopt($ch, CURLOPT_HTTPHEADER, ['Content-Type:application/json']);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$result = curl_exec($ch);
curl_close($ch);
return $result;
}
I have 2 sites, one main, one external. On the main site, I am using Lucene to search through it. The problem is, I am trying to also search through the external site.
The Form action for the external site:
<form action="https://secure.bcchf.ca/SuperheroPages/searchResults.cfm?Event=WOT" method="post" name="search_tribute" >
I've tried to use curl, but it only brings up the search form without actually doing the search (the field is empty as well).
<?php
$ch = curl_init("https://secure.bcchf.ca/SuperheroPages/searchResults.cfm?Event=WOT");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, tname='hello');
$output = curl_exec($ch);
echo $output;
curl_close($ch);
?>
Any tips?
I don't have access to the form action since it's on an external site. All i have is a form that links to it when I submit it.
<?php
$ch = curl_init("https://secure.bcchf.ca/SuperheroPages/searchResults.cfm?Event=WOT");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, array("teamName" => "hello", "searchType" => "team"));
$output = curl_exec($ch);
echo $output;
curl_close($ch);
?>
Can you try this?
I'm pretty sure it's supposed to be teamName instead of tName
Most search engine use GET and not POST .. you can try
// asumption
$_POST['search'] = "hello";
// Return goole Search Result
echo curlGoogle($_POST['search']);
function curlGoogle($keyword) {
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://www.google.com/search?hl=en&q=' . urlencode($keyword) . '&btnG=Google+Search&meta=');
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_FILETIME, true);
$data = curl_exec($ch);
curl_close($ch);
return $data;
}
Or if you want post then
curl_setopt($ch, CURLOPT_POSTFIELDS, array("search"=>"hello"));
Your php code is not valid syntax, it does not compile.
So if this is really what you have, your problem is that your file generates a fatal error.
That being said, this question is hard to answer since we don't know the site you want to grab your search results from.
Try modifying your line like this:
curl_setopt($ch, CURLOPT_POSTFIELDS, "search=hello");
or alternatively
curl_setopt($ch, CURLOPT_POSTFIELDS, array("search" => "hello");
Maby it will work, however it may be that more post data is required or that the element name is not correct.
You have to look at the form or try making a request and look at it with chromes developer tools or firebug.
Also there are a number of ways for external sites to prevent what you are doing, altough evertything can be worked around somehow.
Assuming that is not the case, I hope i could help you.
Try just putting it into an array.
as that will be the variable the $_POST checks on the other side
and just checked your link, its teamName for the field
$fields = array("teamName"=>"julia");
Then..
curl_setopt($ch, CURLOPT_POSTFIELDS, $fields);
So your complete code is...
<?php
$ch = curl_init("https://secure.bcchf.ca/SuperheroPages/searchResults.cfm?Event=WOT");
$fields = array("teamName"=>"julia");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $fields);
$output = curl_exec($ch);
var_dump($output);
curl_close($ch);
?>
I have a Affiliate URL Like http://track.abc.com/?affid=1234
open this link will go to http://www.abc.com
now i want to execute the http://track.abc.com/?affid=1234 Using CURL
and now how i can Get http://www.abc.com
with Curl ?
If you want cURL to follow redirect headers from the responses it receives, you need to set that option with:
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);
You may also want to limit the number of redirects it follows using:
curl_setopt($ch, CURLOPT_MAXREDIRS, 3);
So you'd using something similar to this:
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://track.abc.com/?affid=1234");
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);
curl_setopt($ch, CURLOPT_MAXREDIRS, 3);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
$data = curl_exec($ch);
Edit: Question wasn't exactly clear but from the comment below, if you want to get the redirect location, you need to get the headers from cURL and parse them for the Location header:
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://track.abc.com/?affid=1234");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_HEADER, true);
$data = curl_exec($ch);
This will give you the headers returned by the server in $data, simply parse through them to get the location header and you'll get your result. This question shows you how to do that.
I wrote a function that will extract any header from a cURL header response.
function getHeader($headerString, $key) {
preg_match('#\s\b' . $key . '\b:\s.*\s#', $headerString, $header);
return substr($header[0], strlen($key) + 3, -2);
}
In this case, you're looking for the value of the header Location. I tested the function by retrieving headers from a TinyURL, that redirects to http://google.se, using cURL.
$url = "http://tinyurl.com/dtrkv";
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$data = curl_exec($ch);
curl_close($ch);
$location = getHeader($data, 'Location');
var_dump($location);
Output from the var_dump.
string(16) "http://google.se"
I am able to send the GET request and receive the response at following line.
$curl_resp = curl_exec($curl);
I used the following to parse the response, but it does not work, I have manually set some values to $curl_resp but still not sure how to access the value of each tag of the xml separately.
$xml = simplexml_load_string($curl_resp);
NOTE: I recevice the actual xml but cant parse it, (I need to get each tag's value separately in a variable)
Code:
<?php
$service_url = ' The Url goes here';
$curl = curl_init($service_url);
$curl_post_data = array(
"PASSWORD" => 'pass',
"USERNAME" => 'username'
);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_POSTFIELDS, $curl_post_data);
$curl_resp = curl_exec($curl);
curl_close($curl);
Your variable $curl_response is different than $curl_resp (what you're trying to parse)
You can access the value of each tag just like any other array.
if the CURLOPT_RETURNTRANSFER option is not set then your $curl_resp will just return true/false.
if it is set you may be returning false or a poorly formed xml string. If you post more code or the actual curl response text we may be able to provide more info.
EDIT:
upon reading the code looks like you are assigning the response text to $curl_response instead of $curl_resp
$ch = curl_init();
curl_setopt( $ch, CURLOPT_URL, "your url");
curl_setopt($ch, CURLOPT_USERAGENT, 'Googlebot/2.1 (+http://www.google.com/bot.html)');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$response = curl_exec($ch);
I have been trying to post some variables to a site using POST method, using curl to get some results. I am posting to this link.
http://www.rasta.pk/Lhr/Lhr_Traffic.aspx
At this page you will see a drop down menu .. onchange some values are returned in "Yellow" colored table.
I have monitored this site and trying to get those results by making a post request to that link. But, I am getting "Bad Header" error. I have tried changing things but ubable to find a solution.
Here is my code:
"Canal Bank Rd",
"ScriptManager1 " => "UpdatePanelDDLRoads|DropDownRoads",
"__EVENTARGUMENT" => "",
"__EVENTTARGET" => "DropDownRoads"
);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headerz);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 0);
curl_setopt($ch, CURLOPT_REFERER, "http://www.rasta.pk/Lhr/Lhr_Traffic.aspx");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$output = curl_exec($ch);
curl_close($ch);
echo $output;
?>
There's too little details presented for us to know for sure.
A guess is that you're doing the wrong kind of post, since when you pass in a hash array to CURLOPT_POSTFIELDS it will do a multipart formpost which might not be what the server expects. Pass in a string instead to make a "normal" POST.
If that is not enough, use LiveHTTPHeaders or similar in a browser to figure out exactly what is sent in a "manual" session and then you make sure that your curl program mimics that operation as closely as possible.
