Laravel Queries Strings
提问by Melvin Koopmans
Does anyone know if it's possible to make use of URL query's within Laravel.
有谁知道是否可以在 Laravel 中使用 URL 查询。
Example
例子
I have the following route:
我有以下路线：
Route::get('/text', 'TextController@index');
And the text on that page is based on the following url query:
该页面上的文本基于以下 url 查询：
http://example.com/text?color={COLOR}
How would I approach this within Laravel?
我将如何在 Laravel 中解决这个问题？

For future visitors, I use the approach below for > 5.0. It utilizes Laravel's Requestclassand can help keep the business logic out of your routesand controller.
对于未来的访问者，我使用以下方法进行> 5.0. 它利用 Laravel 的Request类，可以帮助将业务逻辑排除在您的routes和controller.
Example URL
示例网址
admin.website.com/get-grid-value?object=Foo&value=Bar
Routes.php
路由.php
Route::get('get-grid-value', 'YourController@getGridValue');
YourController.php
你的控制器.php
/**
* $request is an array of data
*/
public function getGridValue(Request $request)
{
// returns "Foo"
$object = $request->query('object');
// returns "Bar"
$value = $request->query('value');
// returns array of entire input query...can now use $query['value'], etc. to access data
$query = $request->all();
// Or to keep business logic out of controller, I use like:
$n = new MyClass($request->all());
$n->doSomething();
$n->etc();
}
For more on retrieving inputs from the request object, read the docs.
有关从请求对象检索输入的更多信息，请阅读文档。

Yes, it is possible. Try this:
对的，这是可能的。尝试这个：
Route::get('test', function(){
return "<h1>" . Input::get("color") . "</h1>";
});
and call it by going to http://example.com/test?color=red.
并通过转到调用它http://example.com/test?color=red。
You can, of course, extend it with additional arguments to your heart's content. Try this:
当然，您可以根据自己的喜好使用其他参数对其进行扩展。尝试这个：
Route::get('test', function(){
return "<pre>" . print_r(Input::all(), true) . "</pre>";
});
and add some more arguments:
并添加更多参数：
http://example.com/?color=red&time=now&greeting=bonjour`
This will give you
这会给你
Array
(
[color] => red
[time] => now
[greeting] => bonjour
)

Query params are used like this:
查询参数的使用方式如下：
use Illuminate\Http\Request;
class ColorController extends BaseController{
public function index(Request $request){
$color = $request->query('color');
}

public function fetchQuery(Request $request){
$object = $request->query('object');
$value = $request->query('value');
}
