How do I obtain all the GET parameters on Silex?
提问by fesja
I've been using Silex for a day, and I have the first "stupid" question. If I have:
我已经使用 Silex 一天了，我有第一个“愚蠢”的问题。如果我有：
$app->get('/cities/{city_id}.json', function(Request $request, $city_id) use($app) {
....
})
->bind('city')
->middleware($checkHash);
I want to get all the parameters (city_id) included in the middleware:
我想获取中间件中包含的所有参数（city_id）：
$checkHash = function (Request $request) use ($app) {
// not loading city_id, just the parameter after the ?
$params = $request->query->all();
....
}
So, how do I get city_id (both the parameter name and its value) inside the middleware. I'm going to have like 30 actions, so I need something usable and maintainable.
那么，如何在中间件中获取 city_id（参数名称及其值）。我将有大约 30 个动作，所以我需要一些可用和可维护的东西。
What am I missing?
我错过了什么？
thanks a lot!
多谢！
Solution
解决方案
We need to get those extra parameters of $request->attributes
我们需要获取$request->attributes 的那些额外参数
$checkHash = function (Request $request) use ($app) {
// GET params
$params = $request->query->all();
// Params which are on the PATH_INFO
foreach ( $request->attributes as $key => $val )
{
// on the attributes ParamaterBag there are other parameters
// which start with a _parametername. We don't want them.
if ( strpos($key, '_') != 0 )
{
$params[ $key ] = $val;
}
}
// now we have all the parameters of the url on $params
...
});

In Requestobject you have access to multiple parameter bags, in particular:
在Request对象中，您可以访问多个参数包，特别是：
$request->query- the GET parameters$request->request- the POST parameters$request->attributes- the request attributes (includes parameters parsed from the PATH_INFO)
$request->query- GET 参数$request->request- POST 参数$request->attributes- 请求属性（包括从 PATH_INFO 解析的参数）
$request->querycontains GET parameters only. city_idis not a GET parameter. It's an attribute parsed from the PATH_INFO.
$request->query仅包含 GET 参数。city_id不是 GET 参数。它是从 PATH_INFO 解析的属性。
Silex uses several Symfony Components. Request and Response classes are part of the HttpFoundation. Learn more about it from Symfony docs:
