如何使用Laravel 5获取HTTP主机 [英] How do you get the HTTP host with Laravel 5

问题描述

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相关内容，但是我认为这应该很简单.有人知道该怎么做吗?

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?

推荐答案

好消息！事实证明，这确实很容易，尽管Laravel的Request文档有点缺乏(我想要的方法是从

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 Request class). If you're in a controller method, you can inject the request object, which has a getHttpHost method. This provides exactly what I was looking for:

public function anyMyRoute(Request $request) {
    $host = $request->getHttpHost(); // returns dev.site.com
}

在代码的任何其他位置，您仍然可以使用 辅助功能，因此如下所示:

From anywhere else in your code, you can still access the request object using the request helper function, so this would look like:

$host = request()->getHttpHost(); // returns dev.site.com

如果要在URL中包含http/https部分，则可以直接使用getSchemeAndHttpHost方法:

If you want to include the http/https part of the URL, you can just use the getSchemeAndHttpHost method instead:

$host = $request->getSchemeAndHttpHost(); // returns https://dev.site.com

需要花一些时间来寻找源代码，所以希望对您有所帮助！

It took a bit of digging through the source to find this, so I hope it helps!
