I'm trying to write simple CURL request from server. Script looks like:
$ch = curl_init();
$url = 'http://URL/';
curl_setopt($ch, CURLOPT_URL, $url);
// ADD URL
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Content-Type: application/x-www-form-urlencoded',
'Accept: application/json',
'Authorization: Basic Y291bn54adsASD78asd5LWFkbWlu'));
// ADD HEADER
curl_setopt($ch, CURLOPT_POST, 1);
// SAY IT'S POST
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
if($response === false){
echo 'Curl error: ' . curl_error($ch);
}
else{
$sessionID = json_decode($response, true);
print_r($sessionID);
}
curl_close($ch);
Problem is that I need to add some x-www-form-urlencoded like: grant_type = value, login = value2, password=value3. But I just can't make it work.
Can somebody help please?
The values must be like they would be in an URL (hence the urlencoded), so:
grant_type=value&login=value2&password=value3
If values are not numbers, you will probably need to enclose them between quotes.

I have an array of params which I'm sending in CURL get request but not getting params which I have checked.
I want to send these params(key, value) in curl get request but not sending giving empty data
this is my code you can see that
$params = [];
foreach($product_data->params as $param) {
array_push($params, $param);
}
$curl = curl_init($product_data_url);
$headers = [
'Content-Type: application/json',
'Authorization: Bearer ' . $token,
];
curl_setopt($curl, CURLOPT_HTTPHEADER, $headers);
curl_setopt($curl, CURLOPT_URL, $product_datat_url);
curl_setopt($curl, CURLOPT_CUSTOMREQUEST, "GET");
curl_setopt($curl, CURLOPT_POSTFIELDS, http_build_query($params));
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
$resp = curl_exec($curl);
if($resp === false)
{
echo "Error Number:".curl_errno($curl)."<br>";
echo "Error String:".curl_error($curl);
}
curl_close($curl);
return $resp;
First you have a typo in this line:
curl_setopt($curl, CURLOPT_URL, $product_datat_url);
$product_datat_url should be $product_data_url.
Second, another problem that you are trying to send a post request parameters in get request, As known the get request parameters appears in the url like: url?param1=value¶m2=value so you should add the following before setting the url:
$url = $product_data_url . '?' . http_build_query($params);
curl_setopt($curl, CURLOPT_URL, $url);
And remove this line:
curl_setopt($curl, CURLOPT_POSTFIELDS, http_build_query($params));
Im trying to create a simple api that will post json to an endpoint using curl and php. its giving me an error whereby its saying unsupported media type and i need help seeing what it is i might be doing wrong, here is the code
<?php
$data = array("saleAmount"=>"2000","cashBack"=>"800","posUser"=>"John","tenderType"=>"SWIPE","currency"=>"RTGS","transactionId"=>'0001');
$payload = json_encode($data);
echo $payload;
// prepare curl
$ch = curl_init('http://localhost:9111/api/requests');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLINFO_HEADER_OUT, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $payload);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Content-Type: application/jsonp',
'Content-Length: ' . strlen($payload))
);
// Submit the POST request
$result = curl_exec($ch);
echo json_encode($result);
// Close cURL session handle
curl_close($ch);
?>
The issue is that your API is expecting a different media type than the one you are providing in your quest.
https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/415
Make sure that your API supports the content-type application/json
$url="";//path of api
$ch=curl_init($url);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Content-Type: application/json')
);
$data = array("saleAmount"=>"2000","cashBack"=>"800","posUser"=>"John","tenderType"=>"SWIPE","currency"=>"RTGS","transactionId"=>'0001');
$data=json_encode($data);
curl_setopt($ch,CURLOPT_URL,$url);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);
curl_setopt($ch,CURLOPT_POST,true);
curl_setopt($ch,CURLOPT_POSTFIELDS,$data);
$response=curl_exec($ch);
print_r($response);die;
curl_close($ch);
Append your url in $url and check this once.
I am trying to call an api called Wave I have used cURL before but never with GRAPHQL queries. I am wondering what is wrong with the below when using cURL. I get an error Bad Request Below is an exmple of my code.
This is what the API cURL is
curl -X POST "https://reef.waveapps.com/graphql/public" \
-H "Authorization: Bearer <ACCESS_TOKEN>" \
-H "Content-Type: application/json" \
-d '{ "query": "query { user { id defaultEmail } }" }'
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://reef.waveapps.com/graphql/public');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 0);
curl_setopt($ch, CURLOPT_POSTFIELDS, '{ "query": "query { user { id defaultEmail } }');
curl_setopt($ch, CURLOPT_POST, 1);
$headers = array();
$headers[] = 'Content-Type: application/json';
$headers[] = 'Authorization: Bearer 1212121';
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
$result = curl_exec($ch);
var_dump($result);
if (curl_errno($ch)) {
echo 'Error:' . curl_error($ch);
}
Any help would be helpful.
For those wanting to query a GraphQL service WITHOUT a third party library, I basically took Brian's code and tested against a GraphCMS service I had already written Node.js code for. So I knew the url, authorization token, and query all worked.
<?php
$endpoint = "https://api-euwest.graphcms.com/v1/[[your id number here]]/master";//this is provided by graphcms
$authToken = "[[your auth token]]";//this is provided by graphcms
$qry = '{"query":"query {products(where:{status:PUBLISHED}){title,img,description,costPrice,sellPrice,quantity,sku,categories {name},brand {name}}}"}';
$headers = array();
$headers[] = 'Content-Type: application/json';
$headers[] = 'Authorization: Bearer '.$authToken;
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $endpoint);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 0);
curl_setopt($ch, CURLOPT_POSTFIELDS, $qry);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
$result = curl_exec($ch);
var_dump($result);
if (curl_errno($ch)) {
echo 'Error:' . curl_error($ch);
}
?>
All worked fine.
The auth token is a big long character string provided by GraphCMS and only needs to be passed in the header. So no real tricky authentication process - as long as you have the token.
I can recommend using https://github.com/softonic/graphql-client, it has worked great for us.
A way easier way to go about doing this is by using an API platform. I often use Postman, the platform have the functionality to give you the PHP cURL code for a GraphQL request in the GraphQl tools part of the application.
You can create your own client passing whatever middleware you'd like:
$clientWithMiddleware = \MyGuzzleClientWithMiddlware::build();
$graphQLClient = new \Softonic\GraphQL\Client(
$clientWithMiddleware,
new \Softonic\GraphQL\ResponseBuilder()
);
For an example how to build a Guzzle client with middleware you can check this out:
https://github.com/softonic/guzzle-oauth2-middleware/blob/master/src/ClientBuilder.php
If there is no authentication
You can use file_get_contents instead of curl
$url = http://myapi/graphql?query={me{name}}
$html =file_get_contents($url);
echo $html;
use json in query paramter for graphql;
Bit late but I made this code
$endpoint = "https://gql.waveapps.com/graphql/public";
$authToken = ""; //Your Bearer code
$qry = '{"query": "query {user {id firstName lastName defaultEmail createdAt modifiedAt}}"}';
$headers = array();
$headers[] = 'Content-Type: application/json';
$headers[] = 'Authorization: Bearer '.$authToken;
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $endpoint);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $qry);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
$result = curl_exec($ch);
var_dump($result);
if (curl_errno($ch)) {
echo 'Error:' . curl_error($ch);
}
I have been working on building an Rest API for the hell of it and I have been testing it out as I go along by using curl from the command line which is very easy for CRUD
I can successfully make these call from the command line
curl -u username:pass -X GET http://api.mysite.com/pet/1
curl -d '{"dog":"tall"}' -u username:pass -X GET http://api.mysite.com/pet
curl -d '{"dog":"short"}' -u username:pass -X POST http://api.mysite.com/pet
curl -d '{"dog":"tall"}' -u username:pass -X PUT http://api.mysite.com/pet/1
The above calls are easy to make from the command line and work fine with my api, but now I want to use PHP to create the curl. As you can see, I pass data as a json string. I have read around and I think I can probably do the POST and include the POST fields, but I have not been able to find out how to pass http body data with GET. Everything I see says you must attached it to the url, but it doesn't look that way on the command line form. Any way, I would love it if someone could write the correct way to do these four operations in PHP here on one page. I would like to see the simplest way to do it with curl and php. I think I need to pass everything through the http body because my php api catching everything with php://input
PUT
$data = array('username'=>'dog','password'=>'tall');
$data_json = json_encode($data);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json','Content-Length: ' . strlen($data_json)));
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'PUT');
curl_setopt($ch, CURLOPT_POSTFIELDS,$data_json);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
curl_close($ch);
POST
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS,$data_json);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
curl_close($ch);
GET
See #Dan H answer
DELETE
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "DELETE");
curl_setopt($ch, CURLOPT_POSTFIELDS,$data_json);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
curl_close($ch);
You can use this small library: https://github.com/ledfusion/php-rest-curl
Making a call is as simple as:
// GET
$result = RestCurl::get($URL, array('id' => 12345678));
// POST
$result = RestCurl::post($URL, array('name' => 'John'));
// PUT
$result = RestCurl::put($URL, array('$set' => array('lastName' => "Smith")));
// DELETE
$result = RestCurl::delete($URL);
And for the $result variable:
$result['status'] is the HTTP response code
$result['data'] an array with the JSON response parsed
$result['header'] a string with the response headers
Hope it helps
For myself, I just encode it in the url and use $_GET on the destination page. Here's a line as an example.
$ch = curl_init();
$this->json->p->method = "whatever";
curl_setopt($ch, CURLOPT_URL, "http://" . $_SERVER['SERVER_NAME'] . $this->json->path . '?json=' . urlencode(json_encode($this->json->p)));
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$output = curl_exec($ch);
curl_close($ch);
EDIT: Adding the destination snippet... (EDIT 2 added more above at OPs request)
<?php
if(!isset($_GET['json']))
die("FAILURE");
$json = json_decode($_GET['json']);
$method = $json->method;
...
?>
I was Working with Elastic SQL plugin.
Query is done with GET method using cURL as below:
curl -XGET http://localhost:9200/_sql/_explain -H 'Content-Type: application/json' \
-d 'SELECT city.keyword as city FROM routes group by city.keyword order by city'
I exposed a custom port at public server, doing a reverse proxy with Basic Auth set.
This code, works fine plus Basic Auth Header:
$host = 'http://myhost.com:9200';
$uri = "/_sql/_explain";
$auth = "john:doe";
$data = "SELECT city.keyword as city FROM routes group by city.keyword order by city";
function restCurl($host, $uri, $data = null, $auth = null, $method = 'DELETE'){
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $host.$uri);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, $method);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
if ($method == 'POST')
curl_setopt($ch, CURLOPT_POST, 1);
if ($auth)
curl_setopt($ch, CURLOPT_USERPWD, $auth);
if (strlen($data) > 0)
curl_setopt($ch, CURLOPT_POSTFIELDS,$data);
$resp = curl_exec($ch);
if(!$resp){
$resp = (json_encode(array(array("error" => curl_error($ch), "code" => curl_errno($ch)))));
}
curl_close($ch);
return $resp;
}
$resp = restCurl($host, $uri); //DELETE
$resp = restCurl($host, $uri, $data, $auth, 'GET'); //GET
$resp = restCurl($host, $uri, $data, $auth, 'POST'); //POST
$resp = restCurl($host, $uri, $data, $auth, 'PUT'); //PUT
set one more property curl_setopt($ch, CURLOPT_SSL_VERIFYPEER , false);
I'm trying to make an CURL PUT REQUEST, my code looks like:
public function assignProfile($token, $organizationId, $profileId)
{
//define enviroment and path
$host = enviroment;
$path = "/admin/organizations/".$organizationId."/users";
$data_string = '["'.$profileId.'"]';
// set up the curl resource
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $host.$path);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "PUT");
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_VERBOSE, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Content-Type: application/json',
'Authorization: Bearer '.$token.'',
'Content-Length: ' . strlen($data_string)
));
echo "<br>OK<br>";
// execute the request
$output = curl_exec($ch);
// return ID for a new case
$output = json_decode($output);
var_dump($output);
}
Each part looks correct, when I var_dump $path, $host, even $data_string looks correct. However var_dump() at the end throw just NULL
I expect I'm doing something wrong or missing something really important.
May I ask you for some advise?
Thanks
EDIT:
What i do with it:
// define
define("Audavin","here is some uniqe ID");
.
.
.
$Users = new Users;
// this return Auth token ( I verify this work with echo )
$token = $Users->authorization();
// Calling method mentioned above
$Users->assignProfile($token,"here is org id", Audavin);
I would start by making sure the URL you're making the request to actually works and returns a valid response, you can do so by using a simple REST client (like POSTMAN chrome extension for example)
If you do get a response back, try and see if it's indeed a valid JSON, if not, that could be why you're not getting anything back from json_decode (more on return values here: http://php.net/manual/en/function.json-decode.php)
Finally, It is suggested you add curl_close($ch) to the end of your code to make sure your release the curl handle.
