Php cURL with calling an API with GRAPHQL

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.

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
