How do you get the HTTP host with Laravel 5
提问by Sean the Bean
I'm trying to get the hostname from an HTTP request using Laravel 5, including the subdomain (e.g., dev.site.com). I can't find anything about this in the docs, but I would think that should be pretty simple. Anyone know how to do this?
我正在尝试使用 Laravel 5 从 HTTP 请求中获取主机名，包括子域（例如，dev.site.com）。我在文档中找不到任何关于此的信息，但我认为这应该很简单。有人知道怎么做吗？

Good news! It turns out this is actually pretty easy, although Laravel's Request documentation is a bit lacking (the method I wanted is inherited from Symfony's Requestclass). If you're in a controller method, you can inject the request object, which has a getHttpHostmethod. This provides exactly what I was looking for:
好消息！事实证明这实际上很容易，虽然 Laravel 的 Request 文档有点缺乏（我想要的方法是从Symfony 的Request类继承的）。如果您在控制器方法中，则可以注入具有getHttpHost方法的请求对象。这正是我正在寻找的：
public function anyMyRoute(Request $request) {
$host = $request->getHttpHost(); // returns dev.site.com
}
From anywhere else in your code, you can still access the request object using the requesthelper function, so this would look like:
从代码中的任何其他地方，您仍然可以使用requesthelper 函数访问请求对象，所以这看起来像：
$host = request()->getHttpHost(); // returns dev.site.com
If you want to include the http/https part of the URL, you can just use the getSchemeAndHttpHostmethod instead:
如果要包含 URL 的 http/https 部分，则可以改用该getSchemeAndHttpHost方法：
$host = $request->getSchemeAndHttpHost(); // returns https://dev.site.com
It took a bit of digging through the source to find this, so I hope it helps!
花了一些时间挖掘源代码才找到这个，所以我希望它有所帮助！

There two ways, so be careful:
有两种方法，所以要小心：
<?php
$host = request()->getHttpHost(); // With port if there is. Eg: mydomain.com:81
$host = request()->getHost(); // Only hostname Eg: mydomain.com

laravel 5.6 and above
Laravel 5.6 及以上
request()->getSchemeAndHttpHost()
Example of use in blade :
在刀片中的使用示例：
{{ request()->getSchemeAndHttpHost() }}

You can use request()->url();
您可以使用 request()->url();
Also you can dump the complete request()->headers();
你也可以转储完整的 request()->headers();
And see if that data is useful for you.
看看这些数据是否对你有用。
