laravel determines the request page

As a popular PHP framework, Laravel’s biggest feature is its flexibility and ease of use. During the development process, how to determine the requested page is a topic we need to always pay attention to. This article will give a brief introduction to the related methods of judging the requested page in Laravel.

1. Determine the request method

1.1. Use the isMethod method of the Request class

The isMethod method of Laravel's Request class can be used to determine the request method. For example:

use IlluminateHttpRequest;

Route::post('/submit', function (Request $request) {
    if ($request->isMethod('post')) {
        //提交表单
    }
});

1.2. Use the method name of the Request class

In addition to the isMethod method, you can also use the corresponding method name of the Request class for judgment, for example:

use IlluminateHttpRequest;

Route::post('/submit', function (Request $request) {
    if ($request->isPost()) {
        //提交表单
    }
});

Note: For PUT, PATCH and DELETE requests, you need to add the _method field to the form when using the above methods. For specific methods, please refer to Laravel official documentation.

2. Determine the route of the request

2.1. Use the routeIs method of the Request class

The routeIs method of Laravel's Request class can be used to determine whether the current route is consistent with the specified route. Name matching, for example:

use IlluminateHttpRequest;

Route::get('/page', function (Request $request) {
    if ($request->routeIs('page')) {
        //执行相关操作
    }
})->name('page');

2.2. Use the currentRouteName method of the Route class

The currentRouteName method of Laravel's Route class can be used to get the name of the current route, for example:

use IlluminateSupportFacadesRoute;

Route::get('/page', function () {
    $currentRouteName = Route::currentRouteName();
    if ($currentRouteName == 'page') {
        //执行相关操作
    }
})->name('page');

3. Determine the requested URL

3.1. Use the is method of the Request class

The is method of Laravel's Request class can be used to determine whether the current URL matches the specified URL, for example:

use IlluminateHttpRequest;

Route::get('/page', function (Request $request) {
    if ($request->is('/page')) {
        //执行相关操作
    }
});

3.2. Use the fullUrlIs method of the Request class

The fullUrlIs method of Laravel's Request class can be used to determine whether the current complete URL matches the specified URL, for example:

use IlluminateHttpRequest;

Route::get('/page', function (Request $request) {
    if ($request->fullUrlIs('http://localhost/page')) {
        //执行相关操作
    }
});
