Laravel: Get base url
提问by Inigo
Simple question, but the answer seems quite hard to come by. In Codeigniter, I could load the url helper and then simply do
一个简单的问题，但答案似乎很难得到。在 Codeigniter 中，我可以加载 url helper 然后简单地做
echo base_url();
to get my site's URL. Is there an equivalent in Laravel?
获取我网站的网址。Laravel 中是否有等价物？

You can use the URL facade which lets you do calls to the URL generator
您可以使用 URL 外观，它可以让您调用URL 生成器
So you can do:
所以你可以这样做：
URL::to('/');
You can also use the application container:
您还可以使用应用程序容器：
$app->make('url')->to('/');
$app['url']->to('/');
App::make('url')->to('/');
Or inject the UrlGenerator:
或者注入 UrlGenerator：
<?php
namespace Vendor\Your\Class\Namespace;
use Illuminate\Routing\UrlGenerator;
class Classname
{
protected $url;
public function __construct(UrlGenerator $url)
{
$this->url = $url;
}
public function methodName()
{
$this->url->to('/');
}
}

For Laravel 5 I normally use:
对于 Laravel 5，我通常使用：
<a href="{{ url('/path/uri') }}">Link Text</a>
I'm of the understanding that using the url()function is calling the same Facadeas URL::to()
我的理解是，使用url()函数调用是相同Facade的URL::to()

Updates from 2018 Laravel release(5.7) documentation with some more url() functions and it's usage.
从 2018 Laravel release(5.7) 文档更新了一些 url() 函数及其用法。
Question: To get the site's URL in Laravel?
This is kind of a general question, so we can split it.
问题：要在 Laravel 中获取站点的 URL？
这是一个普遍的问题，所以我们可以拆分它。
1. Accessing The Base URL
1. 访问基本 URL
// Get the base URL.
echo url('');
// Get the app URL from configuration which we set in .env file.
echo config('app.url');
2. Accessing The Current URL
2. 访问当前 URL
// Get the current URL without the query string.
echo url()->current();
// Get the current URL including the query string.
echo url()->full();
// Get the full URL for the previous request.
echo url()->previous();
3. URLs For Named Routes
3. 命名路由的 URL
// http://example.com/home
echo route('home');
4. URLs To Assets(Public)
4. 资产的 URLs(Public)
// Get the URL to the assets, mostly the base url itself.
echo asset('');
5. File URLs
5. 文件 URL
use Illuminate\Support\Facades\Storage;
$url = Storage::url('file.jpg'); // stored in /storage/app/public
echo url($url);
Each of these methods may also be accessed via the URL facade:
这些方法中的每一个也可以通过 URL 门面访问：
use Illuminate\Support\Facades\URL;
echo URL::to(''); // Base URL
echo URL::current(); // Current URL
How to call these Helper functions from blade Template(Views) with usage.
如何从刀片模板（视图）中调用这些辅助函数和用法。
// http://example.com/login
{{ url('/login') }}
// http://example.com/css/app.css
{{ asset('css/app.css') }}
// http://example.com/login
{{ route('login') }}
// usage
<!-- Styles -->
<link href="{{ asset('css/app.css') }}" rel="stylesheet">
<!-- Login link -->
<a class="nav-link" href="{{ route('login') }}">Login</a>
<!-- Login Post URL -->
<form method="POST" action="{{ url('/login') }}">

You can also use URL::to('/') to display image in Laravel. Please see below:
您还可以使用 URL::to('/') 在 Laravel 中显示图像。请参阅以下内容：
<img src="{{URL::to('/')}}/images/{{ $post->image }}" height="100" weight="100">
