How to determine the request source in laravel

Laravel is a powerful PHP framework that provides many convenient operations and components for developing high-quality web applications. When developing web applications, we often need to determine whether the source of the request comes from inside or outside the website. At this time, Laravel provides a very convenient method to implement this function.

Request in Laravel

In Laravel, request (Request) is one of the core components of the entire web application. Whenever a user sends a request to our website, our Laravel application receives the request and handles it accordingly. In Laravel, we can use different methods to obtain different parts of the request, such as request parameters, request header information, request methods, etc.

Laravel provides a method called the is method, which can help us determine the source of the request. This method has two parameters, the first parameter is used to specify the request source, and the second parameter is used to specify the default value.

Check if the request comes from the Web

To check if the request comes from the Web application, we can use the following code:

if ($request->is('web/*')) {
    //
}

Here, the is method uses a wildcard ( * ), indicating that all request URLs starting with web/ are matched.

We can also use the is method to check if the request comes from the command line:

if ($request->is('cli/*')) {
    //
}

    //
}

Sometimes, we need to check whether the request comes from a specific domain name. Laravel provides a reliable way to handle this problem:

if ($request->header('host') === 'example.com') {
    //
}

Here, the header method is used to obtain the domain name information in the request header information.

Check if the request comes from the specified IP

Sometimes we want to check if the request comes from a specific IP address, we can use the following code:

if ($request->ip() === '127.0.0.1') {
    //
}

Here, we use Laravel Provides the ip method to obtain the requested IP address and compare it with the specified IP address.

if ($request->header('User-Agent') === 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.36') {
