using curlto send POST request always outputs the result - php

I'm using curl to send a port request without printing the result using this code
$data = array('username' => 'username', 'password' => 'password');
$url = 'http://urlhere';
$ch = curl_init($url);
$postString = http_build_query($data, '', '&');
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postString);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
// or use this line curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
curl_close($ch);
I've used 1 and true for the last line of code but it always prints the result on the webpage. How to execute curl without outputting the result?


must work as i am using same code in my daily projects and getting back data without getting printed
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);

PHP curl request reading data

I want to send a data using curl and return some data
I'am using the following code
$data = array('type' => 'active');
$result = '';
$url = 'https://example.com/'.$function_name;
$send_data = json_encode($data, TRUE);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_USERAGENT, 'PHP-MCAPI/2.0');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 80);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $send_data);
$result = curl_exec($ch);
curl_close($ch);
print_r($result);exit;
On the receiving end returning the POST data
print_r($_POST);exit;
But I'am getting data in different structure as below
(
[{"type":"active"}] =>
)
I think due to this $_POST['type'] is not getting in the receiving side

cURL does not send postfields

I have been reading documentation and queries for several hours and I think I have a correct POST made with cURL.
It communicates correctly, because I receive the auth key and OK is validated, but then it doesn't receive any parameters from the post. I think some parameter must be missing, but I don't see anything in the documentation.
My code:
$data = "email=name#xxxx.com&template=3";
$url = "https://xxxx.net/xxx/aaa/bbb";
$ch = curl_init();
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
"keyname: keyvalue"
));
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data );
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
$result = curl_exec($ch);
Does anyone know if I should stick some more configuration??

How can I make a CURL request to IP Address PHP?

I am trying to make a CURL request to an IP address, however it just fails and I have no idea why.
This is my code:
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,"127.0.0.1/script.php");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, "postdata=postdata&postdata1=postdata1");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$result = curl_exec($ch);
curl_close ($ch);
However it justs returns an empty result.
Any suggestions here?

Try with:
curl_setopt($ch, CURLOPT_URL,"http://127.0.0.1/script.php");
and CURLOPT_POSTFIELDS sould be an array:
$data = array('postdata' => 'postdata', 'postdata1' => 'postdata1');
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);

Fetching Data from mca.gov.in using curl and PHP

I am trying to fetch the data from http://mca.gov.in. I am using CURL and PHP for extracting the data.
Here is the form : http://www.mca.gov.in/mcafoportal/viewSignatoryDetails.do
When I do the HTML form submit directly through this HTML form to ( "http://www.mca.gov.in/mcafoportal/viewSignatoryDetails.do"), it works.
I developed my own form and submitted directly to the above link and it works too.
However, when I pass the same parameters to retrieve the data using curl, it is not giving any data.
Here is the code I am using to fetch the data from http://mca.gov.in.
$data = http_build_query($post_data);
curl_setopt($ch, CURLOPT_URL, "http://www.mca.gov.in/mcafoportal/viewSignatoryDetailsAction.do");
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$result = curl_exec($ch);
echo $result;
Any idea, what could be wrong or If I have missed anything ?

Your problem is that the url you are trying to fetch uses a captcha and you cannot bypass this by code.
You need to use a this url "http://www.mca.gov.in/mcafoportal/popupSignatories.do" that does not require a captcha.
So change your code to:
curl_setopt($ch, CURLOPT_URL, "http://www.mca.gov.in/mcafoportal/popupSignatories.do");
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, array(
"companyid" => "AAA-4416"
));
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$result = curl_exec($ch);
echo $result;
Additionally if you want the company details, use "http://www.mca.gov.in/mcafoportal/companyMasterDataPopup.do"
curl_setopt($ch, CURLOPT_URL, "http://www.mca.gov.in/mcafoportal/companyMasterDataPopup.do");
curl_setopt($ch, CURLOPT_POSTFIELDS, array(
"method" => "ajaxGetCompanyMasterData",
"companyid" => 'AAA-4416'
));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$result = curl_exec($ch);
echo $result;
Update
There are some new APIs that can be found at company master data API from https://data.gov.in

POST JSON with PHP cURL

I have the following php code
curl_setopt($ch, CURLOPT_URL, $URL);
curl_setopt($ch, CURLOPT_USERAGENT, $this->_agent);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_AUTOREFERER, true);
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, $this->_headers);
curl_setopt($ch, CURLOPT_ENCODING , "gzip");
curl_setopt($ch, CURLOPT_VERBOSE, false);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 120);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_COOKIEFILE, $this->_cookie_file_path);
curl_setopt($ch, CURLOPT_COOKIEJAR, $this->_cookie_file_path);
curl_setopt($ch, CURLOPT_POSTFIELDS, '{"folderId":"1","parameters":{"amount":3,"ascending":false,"offset":0,"sort":"date"}}');
curl_setopt($ch, CURLOPT_POST, 1);
But I don't understand why is not working . The API that I'm posting the JSON to says that the parameters were not received . Is there anything wrong in my code ? I think the whole trick is on the JSON parameters... I'm not sure how to send them as I couldn't see any "nave->value" pair with the http analyzer as it usually appears in simple forms ... just that JSON code without any "name".

You can try as follows.
Basically if we have a array of data then it should be json encoded using php json_encode. And you should also add content-type in header which can be defined in curl as curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));
$data = array("country"=>"US","states"=>array("MHASASAS"=>"MH","XYZABABA"=>"XYZ"));
$postdata = json_encode($data);
$ch = curl_init($URL);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postdata);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));
$result = curl_exec($ch);
curl_close($ch);

you can use this and replace with
curl_setopt($ch, CURLOPT_POSTFIELDS, '{"folderId":"1","parameters":{"amount":3,"ascending":false,"offset":0,"sort":"date"}}');
use this
$Parameters = array(
'MerchantCode' => $MerchantCode,
'PriceValue' => $amount,
'ReturnUrl' => $callback,
'InvoiceNumber' => $resnum,
);
curl_setopt($curl, CURLOPT_POSTFIELDS, json_encode($Parameters));

If:you use post method,you should know that:
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.
#see http://php.net/manual/en/function.curl-setopt.php
So:you can do like this:
$ar_form = array('name'=>'PHPJungle','age'=>66,'gender'=>'male');
$poststr = http_build_query($ar_form ); # important
$options[CURLOPT_HTTPGET] = false;
$options[CURLOPT_POST] = true;
$options[CURLOPT_POSTFIELDS] = $poststr ; //default type:application/x-www-from-urlencoded
curl_setopt_array ( $ch, $options );
# #todo your other codes
This is my class I have used for a long time.The class is based on PHP cURL.
It supports GET/POST，HTTP/HTTPS.
#see https://github.com/phpjungle/iHttp/

You can post a json data with curl like so:
Using Command Prompt:
curl -X POST -H "Content-Type: application/json" -d '{"folderId":"1","parameters":{"amount":3,"ascending":false,"offset":0,"sort":"date"}}' $url
Using PHP:
$data = array("folderId"=>"1","parameters"=>array("amount"=>3,"ascending"=>false,"offset"=>0,"sort"=>"date"));
$postdata = json_encode($data);
OR
$postdata = '{"folderId":"1","parameters":{"amount":3,"ascending":false,"offset":0,"sort":"date"}}';
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postdata);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));
$result = curl_exec($ch);
curl_close($ch);
print_r($result);

You haven't set the content type, so the post data is being sent as form data. Try setting the content type to application/json.
If that doesn't work, try wrapping the json string with an array.

$link = "http://test.domain/myquery";
$json = '{"folderId":"1","parameters":{"amount":3,"ascending":false,"offset":0,"sort":"date"}}';
$postdata = json_decode($json);
echo openurl($link, $postdata);
This works as json decode converts a json string into array.
function openurl($url, $postvars = "") {
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postvars);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, '3');
$content = trim(curl_exec($ch));
curl_close($ch);
return $content;
}

if your API endpoint using body for send request using json data may be you can use Guzzle the doc is here doc.
use GuzzleHttp\Client;
$client = new Client();
$request = $this->client->post($url,array(
'content-type' => 'application/json'
),array());
$request->setBody($json_data);
$response = $request->send();
return $response;
hope this work.

You can do it make by steps:
$data = array(
'folderId'=>"1","parameters"=>array(
"amount"=>"3","ascending"=>false,"offset"=>0,"sort"=>"date"
)
);
$data_string = http_build_query($data);
$ch = curl_init();
curl_setopt($ch,CURLOPT_URL, $url);
curl_setopt($ch,CURLOPT_POST, count($data));
curl_setopt($ch,CURLOPT_POSTFIELDS, $data_string);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$result = curl_exec($ch);
curl_close($ch);
$result = json_decode($result,true);
I don't know if you need the header. I think that by default it is already application/x-www-form-urlencode
If it doesn't work, try changing the $data values in array. Think it helps. :)

I'm not sure, that this is the solution but this works for me when posting json, change the json from
'{"folderId":"1","parameters":{"amount":3,"ascending":false,"offset":0,"sort":"date"}}'
to
"{'folderId':'1','parameters':{'amount':3,'ascending':false,'offset':0,'sort':'date'}}"
The only change i made was the double quotes are now on the outside, that works for me but I'm obviously posting to a different server
Only other help I could offer is to download a network debugging tool such as Fiddler or Charles proxy and monitor the requests sent/received, it could be a case that something else is wrong in your code.
Hope i helped :)

first of all
please check the curl http status code
$http_code= curl_get_info($exec_res,CURL_HTTP_CODE);
then modify this request header set with post header API server add a recorder to log those request info.
