Posting JSON using PHP Curl - php

I'm trying to post some JSON data in PHP on my local server. I have the following code below but it's not working. Did i miss a vital thing?
$url = 'http://localhost/mmcv/chart1.php';
//open connection
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS, $json);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADERS,array('Content-Type: application/json'));
$result = curl_exec($ch);


Maybe your problem is in the receiving script.
Try the following in "mmcv/chart1.php":
$rawInput = file_get_contents('php://input');
if(is_string($rawInput)) {
if(!is_null($jsonInput = json_decode($rawInput, true)))
$_POST = $jsonInput;
}


curl_setopt($ch, CURLOPT_HTTPHEADERS,array('Content-Type: application/json'));
even if you are posting json you still have to send data in url encoded form so send it like
curl_setopt($ch, CURLOPT_HTTPHEADERS,array('Content-Type: application/x-www-form-urlencoded'));
and use
curl_setopt($ch, CURLOPT_POST, TRUE);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
instead of
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS, $json);

Parameter not passing in curl using Php

I am trying to fetch data from webservice(nodejs) using curl in php but i am getting result "lang is required"
i tried with following code but not working for me where i am wrong ?
Here is my code
$post = ['lang'=> "593f973dea53161779dd5660",'password'=> "amit123d"];
$ch = curl_init();
$url="http://xxxxxx:8000/api/employer/login";
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($post));
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
$response = curl_exec($ch);
$result = json_decode($response);
echo "<pre>";print_R($result);

Usually to send post variables i use : the http_build_query function.
$url = "http://xxxxxx:8000/api/employer/login";
$post = ['lang'=> "593f973dea53161779dd5660",'password'=> "amit123d"];
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);
curl_setopt($ch,CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/x-www-form-urlencoded'));
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($post));
$response = curl_exec($ch);
$result = json_decode($response);
echo "<pre>";print_R($result);
It works better.

first check the request whether send post field or not.
$post = ['lang'=> "593f973dea53161779dd5660",'password'=> "amit123d"];
$ch = curl_init();
$url="https://httpbin.org/post";
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($post));
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
$response = curl_exec($ch);
$result = json_decode($response);
echo "<pre>";print_R($result);
the site: https://httpbin.org/ will response the post field if the post data exists.
I think the problem may occurs the nodejs side. Does it check the post field rightly ?
from my experience your code is right.

Hi I want to get information from the API and i POST Json data using PHP Curl but I cannot get the output.Can someone let me know where did I do wrong

Two cURL requests showing the same data when loaded via AJAX

I'm making two seperate cURL requests in the same php page. When I load the page by itself, it works as expected, with each request returning different, correct data.
However, when I load the page via AJAX, the second request shows the same data as the first. Why is this happening? Code follows below:
$auth = base64_encode( 'user:'.$api_key );
$data = array(
'apikey' => $api_key,
);
$json_data = json_encode($data);
$ch = curl_init();
$ch2 = curl_init();
$curlopt_url = "https://us7.api.mailchimp.com/3.0/reports/".$_GET['id'];
curl_setopt($ch, CURLOPT_URL, $curlopt_url);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "GET");
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json','Authorization: Basic '.$auth));
curl_setopt($ch, CURLOPT_USERAGENT, 'PHP-MCAPI/3.0');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_TIMEOUT, 10);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_POSTFIELDS, $json_data);
$result = curl_exec($ch);
$results = json_decode($result, true); ?>
$curlopt_url_b = "https://us7.api.mailchimp.com/3.0/reports/".$_GET['id'].'/sent-to/?count=5000 ';
curl_setopt($ch2, CURLOPT_URL, $curlopt_url_b);
curl_setopt($ch2, CURLOPT_CUSTOMREQUEST, "GET");
curl_setopt($ch2, CURLOPT_HTTPHEADER, array('Content-Type: application/json','Authorization: Basic '.$auth));
curl_setopt($ch2, CURLOPT_USERAGENT, 'PHP-MCAPI/3.0');
curl_setopt($ch2, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch2, CURLOPT_TIMEOUT, 10);
curl_setopt($ch2, CURLOPT_POST, true);
curl_setopt($ch2, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch2, CURLOPT_POSTFIELDS, $json_data);
$recipient_result = curl_exec($ch2);
$recipients = json_decode($recipient_result, true);
When loaded via AJAX, $recipients == $results, when they should return results from completely different end points. What gives?

The problem was with the AJAX request, not the cURL request. The AJAX request had added an additional paramter to the URL (in this case, 'ajax=true'), which was feeding through into $_GET variable, and hence requesting the wrong endpoint. It loaded correctly when loaded independently because the URL was not changed by the JS.

Sending post parameter to a url and reading the response....how to do it..?

I am trying to send the post parameter to a url
http://judis.nic.in/supremecourt/DateQry.aspx
and read the response in in php...
How to do I send and read the response...!
Thanks in advance..
My code...as Below comments
<?php
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://judis.nic.in/supremecourt/DateQry.aspx");
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, "button=Submit");
curl_setopt($ch, CURLOPT_POSTFIELDS, "ddlday1=01");
curl_setopt($ch, CURLOPT_POSTFIELDS, "ddlday2=31");
curl_setopt($ch, CURLOPT_POSTFIELDS, "ddlmonth1=01");
curl_setopt($ch, CURLOPT_POSTFIELDS, "ddlmonth2=01");
curl_setopt($ch, CURLOPT_POSTFIELDS, "ddlreport=A");
curl_setopt($ch, CURLOPT_POSTFIELDS, "ddlyear1=2013");
curl_setopt($ch, CURLOPT_POSTFIELDS, "ddlyear2=2013");
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
$response=curl_exec($ch);
echo $response;
curl_close($ch);
?>

By making use of cURL
Here's an example
<?php
// create a new cURL resource
$ch = curl_init();
// set URL and other appropriate options
curl_setopt($ch, CURLOPT_URL, "http://judis.nic.in/supremecourt/DateQry.aspx");
curl_setopt($ch, CURLOPT_HEADER, 0);
// say if your URL has any POST params
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, "name=John");
// grab URL and pass it to the browser
$response=curl_exec($ch);
//Display your response
echo $response;
// close cURL resource, and free up system resources
curl_close($ch);
?>
EDIT:
Concatenate the fields like this
//Since you are using multiple fields .. do like this
$postFields="button=Submit&ddlday=01&ddlday2=31&ddlmonth1=01&ddlmonth2=01&ddlreport=A&ddlyear1=2013&ddlyear2=2013";
curl_setopt($ch, CURLOPT_POSTFIELDS, $postFields);

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.
