🐥 Using a cookie jar with the Laravel HTTP client

If you want to do multiple HTTP requests in a row using the HTTP client from Laravel and persist cookies between them, you can use a cookie jar. This is a class that stores cookies and sends them back to the server when needed. Here's how you can use it:

use GuzzleHttp\Cookie\CookieJar;
use Illuminate\Support\Facades\Http;

// Create a cookie jar to store cookies
$cookieJar = new CookieJar();

// Create a new HTTP client with the cookie jar
// You can also set other options here, like the base URL or whether to follow redirects
$client = Http::baseUrl('https://www.mywebsite.com')
    ->withOptions(['cookies' => $cookieJar])
    ->withoutRedirecting()
    ->throw();

// Make a request that sets a cookie (e.g., logging in)
$authResp = $client->asForm()->post(
    url: '/login',
    data: [
        'username' => 'username',
        'password' => 'password',
    ]
);

// Store the cookies from the response in the cookie jar
$cookies = $authResp->cookies();
foreach ($cookies as $cookie) {
    $cookieJar->setCookie($cookie);
}

// Make another request that requires authentication (which relies on the cookies being present)
$authenticatedResponse = $client->get('/authenticated-page');

If you want to do the same in Golang, you can do this:

package main

import (
    "bytes"
    "fmt"
    "net/http"
    "net/http/cookiejar"
    "net/url"
)

func main() {
    // Create a cookie jar to store cookies
    cookieJar, _ := cookiejar.New(nil)

    // Create a new HTTP client with the cookie jar
    client := &http.Client{
        Jar: cookieJar, // Use this cookie jar
        CheckRedirect: func(req *http.Request, via []*http.Request) error {
            return http.ErrUseLastResponse // Don't follow redirects
        },
    }

    // Create a request body with the login credentials
    params := url.Values{}
    params.Set("username", "username")
    params.Set("password", "password")
    body := bytes.NewBufferString(params.Encode())

    // Make a request that sets a cookie (e.g., logging in)
    // The response cookies will automatically be stored in the cookie jar
    authReq, _ := http.NewRequest(http.MethodPost, "https://www.mywebsite.com/login", body)
    _, _ = client.Do(authReq)

    // Make another request that requires authentication (which relies on the cookies being present)
    authenticatedReq, _ := http.NewRequest(http.MethodGet, "https://www.mywebsite.com/authenticated-page", nil)
    authenticatedResp, _ := client.Do(authenticatedReq)
    defer authenticatedResp.Body.Close()

    // Print the response status and headers
    fmt.Println("response Status : ", authenticatedResp.Status)
    fmt.Println("response Headers : ", authenticatedResp.Header)
}
