CURL request using DELETE method in Magento 2

Question

I am trying to call a curl request for delete method using Magento\Framework\HTTP\Client\Curl.php.

In this class makeRequest method is responsible for sending curl request. But as I can see that this method is protected so I can't call it directly.

makeRequest method in Magento\Framework\HTTP\Client\Curl.php

/**
 * Make request
 * @param string $method
 * @param string $uri
 * @param array $params
 * @return void
 * @SuppressWarnings(PHPMD.CyclomaticComplexity)
 * @SuppressWarnings(PHPMD.NPathComplexity)
 */
protected function makeRequest($method, $uri, $params = [])
{
 $this->_ch = curl_init();
 $this->curlOption(CURLOPT_URL, $uri);
 if ($method == 'POST') {
 $this->curlOption(CURLOPT_POST, 1);
 $this->curlOption(CURLOPT_POSTFIELDS, http_build_query($params));
 } elseif ($method == "GET") {
 $this->curlOption(CURLOPT_HTTPGET, 1);
 } else {
 $this->curlOption(CURLOPT_CUSTOMREQUEST, $method);
 }
 if (count($this->_headers)) {
 $heads = [];
 foreach ($this->_headers as $k => $v) {
 $heads[] = $k . ': ' . $v;
 }
 $this->curlOption(CURLOPT_HTTPHEADER, $heads);
 }
 if (count($this->_cookies)) {
 $cookies = [];
 foreach ($this->_cookies as $k => $v) {
 $cookies[] = "{$k}={$v}";
 }
 $this->curlOption(CURLOPT_COOKIE, implode(";", $cookies));
 }
 if ($this->_timeout) {
 $this->curlOption(CURLOPT_TIMEOUT, $this->_timeout);
 }
 if ($this->_port != 80) {
 $this->curlOption(CURLOPT_PORT, $this->_port);
 }
 //$this->curlOption(CURLOPT_HEADER, 1);
 $this->curlOption(CURLOPT_RETURNTRANSFER, 1);
 $this->curlOption(CURLOPT_HEADERFUNCTION, [$this, 'parseHeaders']);
 if (count($this->_curlUserOptions)) {
 foreach ($this->_curlUserOptions as $k => $v) {
 $this->curlOption($k, $v);
 }
 }
 $this->_headerCount = 0;
 $this->_responseHeaders = [];
 $this->_responseBody = curl_exec($this->_ch);
 $err = curl_errno($this->_ch);
 if ($err) {
 $this->doError(curl_error($this->_ch));
 }
 curl_close($this->_ch);
}

I have to call one of public method of this class which is calling makeRequest method. When I check this I can see 2 public methods for GET and POST request which are calling protected method makeRequest. No other method for DELETE which is calling method makeRequest.

/**
 * Make GET request
 *
 * @param string $uri uri relative to host, ex. "/index.php"
 * @return void
 */
public function get($uri)
{
 $this->makeRequest("GET", $uri);
}
/**
 * Make POST request
 *
 * @param string $uri
 * @param array $params
 * @return void
 *
 * @see \Magento\Framework\HTTP\Client#post($uri, $params)
 */
public function post($uri, $params)
{
 $this->makeRequest("POST", $uri, $params);
}

Now my question is that how can I solve my problem or is this bug in magento 2.1.7 or may be I am getting incorrectly. Please help me if I am doing anything wrong.

class reference curl.php

Answer 1

Use this object instead:

$request = new \Zend\Http\Request();

Then set the method to

$request->setMethod(\Zend\Http\Request::METHOD_DELETE);

For more information, read the tutorial in the following link: http://devdocs.magento.com/guides/v2.1/get-started/gs-web-api-request.html

• Ramkishan Suthar: hello @Toan Tam, I am not sure if we can use it for curl request ?
• Ramkishan Suthar: I think it is for rest api calls.
• Toan Tam: The main purpose of curl request is to make a http request. And the \Zend\Http\Request() class is suitable in this case.
• Ramkishan Suthar: ok then let me try

Answer 2

This cannot be done without extending the core Curl Class and its easy to extend though. Plz refer the below sample code.

Extend the Core Curl Class

declare(strict_types=1);
namespace Company\Module\Model;
use Magento\Framework\HTTP\Client\Curl as CurlLibrary;
class Curl extends CurlLibrary
{
 /**
 * Make DELETE request
 *
 * The Magento Default curl library dosent support delete method
 *
 * @param string $uri
 * @return void
 */
 public function delete($uri)
 {
 $this->makeRequest("DELETE", $uri);
 }
}

Then you can just call

 use Company\Module\Model\Curl;
 public function __construct(
 Curl $curl,
 ) {
 $this->curl = $curl;
 }
 public function execute() {
 $this->curl->delete("delteURL")
 }
