Multiple methods for laravel to obtain request path

Laravel is a popular PHP framework that is widely used in web development. In web development, we often need to get the request path to handle the request. Laravel provides a variety of methods to get the request path. In this article, we will learn about these methods and their uses.

1. Use the Illuminate\Http\Request class

The Illuminate\Http\Request class is one of the core classes of Laravel. It encapsulates HTTP requests and provides many useful methods. To get the path of the current request, we can use the path() method of the Request class. This method returns the path of the current request, excluding query parameters. The sample code is as follows:

use Illuminate\Http\Request;

Route::get('/hello', function (Request $request) {
    $path = $request->path();
    echo $path; // 输出: /hello
});

If you want to obtain the complete request URL, including query parameters, you can use the fullUrl() method of the Request class. The sample code is as follows:

use Illuminate\Http\Request;

Route::get('/hello', function (Request $request) {
    $url = $request->fullUrl();
    echo $url; // 输出: http://example.com/hello?name=world
});

In addition to the above methods, the Request class also provides many other useful methods, such as is(), method(), input(), etc. See the Laravel documentation for more information.

2. Use the Illuminate\Routing\Route class

In Laravel, the Route class represents a route, which contains information such as the route's URL, request method, and handler. To get the route of the current request, we can use the current() method of the Route class. This method returns the routing object of the current request, from which we can obtain the request path, URL and other information. The sample code is as follows:

use Illuminate\Routing\Route;

Route::get('/hello', function () {
    $route = Route::current();
    $path = $route->getPath(); // 获取请求路径
    $url = $route->getUri(); // 获取请求URL
    echo $path; // 输出: /hello
    echo $url; // 输出: /hello
});

3. Use the url() auxiliary function

Laravel provides a url() auxiliary function for generating URLs. If no parameters are passed, the current requested URL is returned. The sample code is as follows:

Route::get('/hello', function () {
    $url = url();
    echo $url; // 输出: http://example.com/hello
});

If you want to get the path of the current request, you can use the parse_url() function. The sample code is as follows:

Route::get('/hello', function () {
    $url = url();
    $path = parse_url($url, PHP_URL_PATH);
    echo $path; // 输出: /hello
});
