I try to send a post request to another php page with the following code:
$vars = ['val1' => 'myval'];
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POSTFIELDS, $vars);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_REFERER, $_SERVER['REQUEST_URI']);
curl_setopt($ch, CURLOPT_VERBOSE, TRUE);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, TRUE);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);
curl_setopt($ch, CURLOPT_MAXREDIRS, 4);
curl_setopt($ch, CURLOPT_POST, TRUE);
curl_setopt($ch, CURLOPT_USERPWD, "username:password");
$data = curl_exec($ch);
curl_close($ch);
But on the target page, var_dump($_POST); will output only "1". I had expected something like:
array(val1 = myval) or something similar. So that i can check with isset($_POST["val1"]) if this exists and contains "myval".
Any ideas whats wrong with the request?
Edit:
I have now changed my code to the following:
<?php
$data = array(
'foo'=>'bar',
'baz'=>'boom',
'cow'=>'milk',
'php'=>'hypertext processor');
$ch=curl_init();
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data));
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/x-www-form-urlencoded'));
curl_setopt($ch, CURLOPT_URL, "target.php");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
curl_close($ch);
echo $response;
?>
And in target.php:
<?php
echo print_r($_POST, true));
?>
But there is no response. Both files are in the same dir at the server.
That's because curl_setopt() doesn't accept such complext types as array ;) You need to present your data in form of a query string: "postvar1=value1&postvar2=value2&postvar3=value3".
$format = http_build_query($vars);
curl_setopt($ch, CURLOPT_POSTFIELDS, $format);
or
$format = "val1=my-value"; // be careful to create proper encoding
curl_setopt($ch, CURLOPT_POSTFIELDS, $format);
If you're using CURLOPT_POSTFIELDS, you don't need to set CURLOPT_POST as well. In fact, setting it after will result in a potentially incorrect header being sent.
CURLOPT_POSTFIELDS accepts an array, and will set the Content-Type header to multipart/form-data if one is provided. Later, setting CURLOPT_POST will overwrite this to application/x-www-form-urlencoded, and means that the PHP script at the other end will expect data encoded as an HTTP query-string. This is why you're having problems.
You can fix this either by encoding $vars correctly before sending (using http_build_query, as in the other answer), or just remove the call to set CURLOPT_POST. I'd recommend the latter.
I think, i got it. When i set as target something like "target.php", data was not send. But when i use a complete URL, like https://myserver.com/target.php, this will work as expected. Sometimes, its to easy... sorry for stealing your time.
after I succeeded in making a POST request and grab the values in the web service i'm building. I'm facing a problem regarding the Put Request. I managed to make the Put Request and I sent an array containing name and id for the update purpose this way:
curl_setopt($ic, CURLOPT_POSTFIELDS, http_build_query($data));
But when I try to grab the id sent using $_POST['id'] I get the undefined index error, I printed_r($_POST) and it's empty. Now I dont't believe there is a super global array for PUT like for POST and even if it exists , I don't think there is :
curl_setopt($ic, CURLOPT_PUTFIELDS, http_build_query($data));
in curl have you even been through a similar error? any idea?
To take a look at my previous post concerning the post request to have a better understanding of what I'm trying to do , it's here
Try this
curl_setopt($ic, CURLOPT_PUTFIELDS, json_encode($data));
and take it by
$array_get = json_decode(file_get_contents('php://input'));
use this CURLOPT_CUSTOMREQUEST =PUT and then just set values with CURLOPT_POSTFIELDS
or
you can use custom header CURLOPT_HTTPHEADER
eg.
curl_setopt($ch, CURLOPT_HTTPHEADER, array('X-HTTP-Method-Override: PUT'));
The script below demonstrates how you make a PUT request.
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "url");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "PUT"); // note the PUT here
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Content-Type: application/json',
'Content-Length: ' . strlen($data_string)
));
// execute the request
$output = curl_exec($ch);
// close curl resource to free up system resources
curl_close($ch);
The $_POST only for method=post;
You use method=put, so the $_POST is empty.
You can get the putdata like this:
$_PUT = array();
if('PUT' == $_SERVER['REQUEST_METHOD']){
parse_str(file_get_contents('php://input'), $_PUT);
}
This is the secret to sending a PUT request:
curl_setopt($ch, CURLOPT_POST, true); // <-- NOTE this is POST
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "PUT"); // <-- NOTE this is PUT
A full example:
$vals = array("email" => "hi#example.com", "phone" => "12345");
$jsonData = json_encode($vals);
curl_setopt($ch, CURLOPT_POST, true); // <-- NOTE this
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "PUT"); // <-- NOTE this
//We want the result / output returned.
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Content-Type:application/json',
'Content-Length:' . strlen($jsonData),
'X-Apikey:Any_other_header_value_goes_here'
));
//Our fields.
curl_setopt($ch, CURLOPT_POSTFIELDS, $jsonData);
//Execute the request.
$response = curl_exec($ch);
echo $response;
i'm trying using cURL for a GET request like this:
function connect($id_user){
$ch = curl_init();
$headers = array(
'Accept: application/json',
'Content-Type: application/json',
);
curl_setopt($ch, CURLOPT_URL, $this->service_url.'user/'.$id_user);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_HEADER, 0);
$body = '{}';
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "GET");
curl_setopt($ch, CURLOPT_POSTFIELDS,$body);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// Timeout in seconds
curl_setopt($ch, CURLOPT_TIMEOUT, 30);
$authToken = curl_exec($ch);
return $authToken;
}
As you an see i want to pass $body as the request's body , but i don't know if its correct or not and i can't debug this actually, do you know if is the right to use curl_setopt($ch, CURLOPT_POSTFIELDS,$body); with a GET request?
Cause this enteire code works perfect with POST, now i'm trying change this to GET as you can see
The accepted answer is wrong. GET requests can indeed contain a body. This is the solution implemented by WordPress, as an example:
curl_setopt( $ch, CURLOPT_CUSTOMREQUEST, 'GET' );
curl_setopt( $ch, CURLOPT_POSTFIELDS, $body );
EDIT: To clarify, the initial curl_setopt is necessary in this instance, because libcurl will default the HTTP method to POST when using CURLOPT_POSTFIELDS (see documentation).
CURLOPT_POSTFIELDS as the name suggests, is for the body (payload) of a POST request. For GET requests, the payload is part of the URL in the form of a query string.
In your case, you need to construct the URL with the arguments you need to send (if any), and remove the other options to cURL.
curl_setopt($ch, CURLOPT_URL, $this->service_url.'user/'.$id_user);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_HEADER, 0);
//$body = '{}';
//curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "GET");
//curl_setopt($ch, CURLOPT_POSTFIELDS,$body);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
<?php
$post = ['batch_id'=> "2"];
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,'https://example.com/student_list.php');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($post));
$response = curl_exec($ch);
$result = json_decode($response);
curl_close($ch); // Close the connection
$new= $result->status;
if( $new =="1")
{
echo "<script>alert('Student list')</script>";
}
else
{
echo "<script>alert('Not Removed')</script>";
}
?>
For those coming to this with similar problems, this request library allows you to make external http requests seemlessly within your php application. Simplified GET, POST, PATCH, DELETE and PUT requests.
A sample request would be as below
use Libraries\Request;
$data = [
'samplekey' => 'value',
'otherkey' => 'othervalue'
];
$headers = [
'Content-Type' => 'application/json',
'Content-Length' => sizeof($data)
];
$response = Request::post('https://example.com', $data, $headers);
// the $response variable contains response from the request
Documentation for the same can be found in the project's README.md
you have done it the correct way using
curl_setopt($ch, CURLOPT_POSTFIELDS,$body);
but i notice your missing
curl_setopt($ch, CURLOPT_POST,1);
What do I have to do on the server page and how to receive this xml file? I'm stuck.
The xml is fine, it is checked with simplexml_load_string.
$var='caca';
$login_xml ='<xml>'.
'<action>log_in</action>'.
'<parameters>'.
'<username>'.$var.'</username>'.
'<pass>abdef01</pass>'.
'</parameters>'.
'</xml>';
$URL = "http://myurl.com/login.php/";
$ch = curl_init($URL);
curl_setopt($ch, CURLOPT_MUTE, 1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: text/xml'));
curl_setopt($ch, CURLOPT_POSTFIELDS, "$login_xml");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$output = curl_exec($ch);
curl_close($ch);
Thank you for your time.
Since the data is send as text/xml and not as url-encoded form-data, you can't use $_POST. You have to read the raw request from the php://input stream
$xml = file_get_contents('php://input');
You have an error in your CURLOPT_POST_FIELDS:
This option, must be an array:
...
$data = array('xml' => $login_xml);
...
And then:
...
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
...
This sends the value 'xml' as post field;
Hope this helps.
I have the following php code
curl_setopt($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.
