Laravel 5 Illuminate\Http\Request has method not allowing static call
提问by Life4Cali
I'm trying to call the Illuminate\Http\Request has method from one of my controllers.
我正在尝试从我的一个控制器调用 Illuminate\Http\Request has 方法。
Request::has('fields')
Following from the documentation exactly, yet I'm getting an error thrown:
完全遵循文档，但我收到了一个错误：
Non-static method Illuminate\Http\Request::has() should not be called statically, assuming $this from incompatible context
非静态方法 Illuminate\Http\Request::has() 不应静态调用，假设 $this 来自不兼容的上下文
I'm not sure what I'm doing wrong here, I tried following the documentation as closely as possible.
我不确定我在这里做错了什么，我尝试尽可能密切地遵循文档。

The problem is you are using the wrong Requestclass. You need to import the Facade:
问题是您使用了错误的Request类。您需要导入 Facade：
use Illuminate\Support\Facades\Request;
回答by Tanvir Gaus
The use Illuminate\Support\Facades\Request; is using the Facade which is not good practice. should use Illuminate\Http\Request; and get the request available via the method or constructor ie.-
使用 Illuminate\Support\Facades\Request; 正在使用 Facade，这不是很好的做法。应该使用 Illuminate\Http\Request; 并通过方法或构造函数获取请求，即。-
public function __construct(Request $request) {
$this->request = $request;
}
and then in the method use it, ie.
然后在方法中使用它，即。
public function checkText() {
$txt = $this->request->has('txt');
return $txt;
}

Try using Input::has() instead then use Input::get() to actually grab the corresponding POSTED/GET var.
尝试使用 Input::has() 而不是使用 Input::get() 来实际获取相应的 POSTED/GET var。
