Laravel is a PHP framework that provides a clean and simple syntax for web developers. One of the most powerful features of Laravel is its HTTP client, which makes it easy to send HTTP requests and handle responses. In this article, we will explore how to use the curl request in Laravel to perform various types of HTTP requests, including GET, POST, PUT, DELETE, and others.
Before we dive into the code examples, let's take a brief look at what curl is and why it's important.
What is CURL?
CURL stands for "Client for URLs" and is a command-line tool that allows you to transfer data from or to a server. It supports various protocols, including HTTP, FTP, SMTP, and others. CURL is widely used for web development and testing, and it's available on most operating systems, including Windows, macOS, and Linux.
Why use CURL in Laravel?
Laravel provides a convenient HTTP client for sending HTTP requests, which is built on top of the Guzzle HTTP client library. However, sometimes, you might want to use the curl request in Laravel for more control and customization over your HTTP requests. For example, if you want to set custom headers, perform a request to a URL that requires authentication, or check the response code, curl can be a great option.
Now that we have a basic understanding of curl and its importance in Laravel, let's dive into the code examples.
How to send a GET request using CURL in Laravel
A GET request is the most common type of HTTP request and is used to retrieve data from a server. The following code example demonstrates how to send a GET request using curl in Laravel:
$curl = curl_init();
curl_setopt_array($curl, [
CURLOPT_URL => "https://example.com",
CURLOPT_RETURNTRANSFER => true,
CURLOPT_ENCODING => "",
CURLOPT_MAXREDIRS => 10,
CURLOPT_TIMEOUT => 0,
CURLOPT_FOLLOWLOCATION => true,
CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
CURLOPT_CUSTOMREQUEST => "GET",
]);
$response = curl_exec($curl);
$err = curl_error($curl);
curl_close($curl);
if ($err) {
echo "cURL Error #:" . $err;
} else {
echo $response;
}
In the code above, we first initialize a curl session using the curl_init() function. Then, we set various options for the curl request using the curl_setopt_array() function, such as the URL to send the request to, the maximum number of redirects, the HTTP version, and the request type.
Finally, we execute the curl request using the curl_exec() function and retrieve the response. If there is an error, we print it using the curl_error() function. Finally, we close the curl session using the curl_close() function.
How to send a POST request using CURL in Laravel
A POST request is used to send data to a server, for example, to create a new resource or update an existing one. The following code
How to send a PUT request using CURL in Laravel
A PUT request is used to update an existing resource on a server. The following code example demonstrates how to send a PUT request using curl in Laravel:
$curl = curl_init();
curl_setopt_array($curl, [
CURLOPT_URL => "https://example.com/api/resource/1",
CURLOPT_RETURNTRANSFER => true,
CURLOPT_ENCODING => "",
CURLOPT_MAXREDIRS => 10,
CURLOPT_TIMEOUT => 0,
CURLOPT_FOLLOWLOCATION => true,
CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
CURLOPT_CUSTOMREQUEST => "PUT",
CURLOPT_POSTFIELDS => json_encode([
"field1" => "value1",
"field2" => "value2",
]),
CURLOPT_HTTPHEADER => [
"Content-Type: application/json",
],
]);
$response = curl_exec($curl);
$err = curl_error($curl);
curl_close($curl);
if ($err) {
echo "cURL Error #:" . $err;
} else {
echo $response;
}
In the code above, we set the CURLOPT_CUSTOMREQUEST option to "PUT" to specify the request type, and we set the CURLOPT_POSTFIELDS option to the data we want to send to the server. We also set the Content-Type header to application/json to indicate that the request body contains JSON data.
How to send a DELETE request using CURL in Laravel
A DELETE request is used to delete a resource on a server. The following code example demonstrates how to send a DELETE request using curl in Laravel:
$curl = curl_init();
curl_setopt_array($curl, [
CURLOPT_URL => "https://example.com/api/resource/1",
CURLOPT_RETURNTRANSFER => true,
CURLOPT_ENCODING => "",
CURLOPT_MAXREDIRS => 10,
CURLOPT_TIMEOUT => 0,
CURLOPT_FOLLOWLOCATION => true,
CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
CURLOPT_CUSTOMREQUEST => "DELETE",
]);
$response = curl_exec($curl);
$err = curl_error($curl);
curl_close($curl);
if ($err) {
echo "cURL Error #:" . $err;
} else {
echo $response;
}
In the code above, we set the CURLOPT_CUSTOMREQUEST option to "DELETE" to specify the request type.
