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);

Thanks for the PUT, if you can add the GET (with json in the body) and POST i'll accept
@Gilberg added for POST. In GET-request data is passing through url :)
Thanks, I can't use Dan's because my api is waiting for php://input and if I include it in the url it won't go to the php://input stream. In short I can't grab it from $_GET, I could but it would be a small headache. I can do it easliy from the command line with curl -d '{json-string}' -X GET http://api.mysite.com/user so there has got to be a way to mimic that in php
Thanks @voodoo4q7 I'll accept, but I would still like to see how to pass data in the body of a GET. I know my server accepts it so it is not a problem for me.
Could you use CURLOPT_PUT as well?

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; ... ?>

Thanks, could you write out your complete curl code in php to make it clear how you define POST,GET,PUT,DELETE. My API looks for those methods.
Added. It's just a simple HTTP request, but as you can see on the destination I use GET. It's literally just to move a json string around (for example, from my application front end, to script1, to script2, which then gets replied back to the app front end -- not included in source).
+1, but I am going to wait for the POST, PUT and DELETE because the rest api I wrote needs those

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);

This is bad advice. Setting that flag means you're not validating the SSL certificate. It opens you up to DNS hijacking.
