I'm playing with Slim PHP as a framework for a RESTful API, and so far it's great. Super easy to work with, but I do have one question I can't find the answer to. How do I grab GET params from the URL in Slim PHP?

例如，如果我想使用以下内容:

For example, if I wanted to use the following:

推荐答案

您可以在 Slim 框架内非常轻松地做到这一点，您可以使用:

You can do this very easily within the Slim framework, you can use:

$paramValue = $app->request()->params('paramName');

$app 这里是一个 Slim 实例.

$app here is a Slim instance.

或者如果你想更具体

//获取参数

$paramValue = $app->request()->get('paramName');

//POST 参数

$paramValue = $app->request()->post('paramName');

您会在特定路线中像这样使用它

You would use it like so in a specific route

$app->get('/route',  function () use ($app) {
          $paramValue = $app->request()->params('paramName');
});

您可以阅读有关请求对象的文档http://docs.slimframework.com/request/variables/

You can read the documentation on the request objecthttp://docs.slimframework.com/request/variables/

截至 Slim v3:

$app->get('/route', function ($request, $response, $args) {
    $paramValue = $request->params(''); // equal to $_REQUEST
    $paramValue = $request->post(''); // equal to $_POST
    $paramValue = $request->get(''); // equal to $_GET

    // ...

    return $response;
});
