Passing JSON to PHP CURL [duplicate] - php

Question

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

Answer 1

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);
