Issue with Multiple Laravel API Requests via cURL on Nginx in Laragon.

Issue with Multiple Laravel API Requests via cURL on Nginx in Laragon.

When making multiple API requests using cURL on Nginx in Laragon, you might encounter some issues. In this answer, we will discuss the possible causes and solutions for this problem.

First, let's understand the context. Laragon is a local development environment for PHP and MySQL that comes with a built-in web server (Apache) and a reverse proxy (Nginx). When you make API requests using cURL on Nginx, the requests are proxied through Nginx to Laragon's Apache server, which then handles the requests and returns the responses.

Now, let's discuss the possible causes and solutions for the issue with multiple Laravel API requests via cURL on Nginx in Laragon:

  1. PHP Worker Processes: Laravel uses PHP-FPM (FastCGI Process Manager) to manage PHP worker processes. When you make multiple requests, Laravel spawns new PHP worker processes to handle each request. However, if you make too many requests too quickly, Laragon's Nginx might not be able to spawn new PHP worker processes fast enough, resulting in timeouts or errors.

Solution: You can increase the number of PHP worker processes by editing the php-ini.ini file in Laragon's etc directory. Add the following lines to the file:

pm.max_children = 10
pm.start_servers = 2
pm.min_spare_servers = 1
pm.max_spare_servers = 3

This will allow Laragon to spawn up to 10 PHP worker processes, with 2 of them being started immediately and 3 being kept as spares.

  1. Nginx Timeouts: Nginx might set timeouts for API requests, which can result in errors or timeouts if the requests take too long to complete.

Solution: You can increase Nginx's timeouts by editing the nginx.conf file in Laragon's etc directory. Add the following lines to the http block:

client_body_timeout 60s;
client_header_timeout 60s;
send_timeout 60s;

This will set the client body timeout, client header timeout, and send timeout to 60 seconds.

  1. Laravel CSRF Protection: Laravel uses CSRF (Cross-Site Request Forgery) protection to prevent unauthorized API requests. However, when making multiple API requests using cURL, you might encounter issues with CSRF tokens.

Solution: You can disable CSRF protection for API requests by adding the following line to your .env file:

APP_TOKEN=your_token_here

Then, in your app/Http/Kernel.php file, add the following line to the $routeMiddleware array:

'api.csrf' => \Illuminate\Routing\Middleware\CSRF::class,

And add the following line to the $middlewareGroups array:

'api' => [
    \App\Http\Middleware\Cors::class,
    \App\Http\Middleware\ThrottleRequests::class,
    \Illuminate\Routing\Middleware\SubscriptionThrottle::class,
    \Illuminate\Routing\Middleware\CSRF::class,
],

Then, in your routes/api.php file, add the following line at the top:

Route::middleware('api')->group(function () {
    // Your API routes here
});

Finally, in your app/Http/Kernel.php file, add the following line to the $middlewareGroups array:

'api' => [
    // Your API middleware here
],

And add the following line to the $routeMiddleware array:

'api.auth' => \App\Http\Middleware\Authenticate::class,

Then, in your routes/api.php file, add the following line at the top of each route definition:

Route::middleware('api.auth')->group(function () {
    // Your API authentication routes here
});

This will disable CSRF protection for all API requests and add authentication middleware to your API authentication routes.

  1. Laravel Throttling: Laravel includes throttling middleware to prevent excessive API requests from overwhelming your server. However, when making multiple API requests using cURL, you might encounter issues with throttling.

Solution: You can increase the number of requests allowed per minute by editing the .env file and adding the following line:

RATE_LIMIT_MAX_REQUESTS=1000

This will allow up to 1000 requests per minute.

  1. Laravel CORS: Laravel includes CORS (Cross-Origin Resource Sharing) middleware to allow API requests from different origins. However, when making multiple API requests using cURL, you might encounter issues with CORS.

Solution: You can add the following lines to your app/Http/Kernel.php file to enable CORS for all API routes:

protected $middlewareGroups = [
    'api' => [
        // Your API middleware here
