使用Aura路由器与Aura调度员

Question

有没有使用Aura路由器和dispatcher的示例/教程？我在文档页面上找到了一个示例代码：

// dispatch the request to the route handler.
// (consider using https://github.com/auraphp/Aura.Dispatcher
// in place of the one callable below.)
$callable = $route->handler;
$response = $callable($request);

// emit the response
foreach ($response->getHeaders() as $name => $values) {
    foreach ($values as $value) {
        header(sprintf('%s: %s', $name, $value), false);
    }
}
http_response_code($response->getStatusCode());
echo $response->getBody();

我想知道如何将Aura调度程序与这个示例代码集成。

第二个问题是，当我们想要使用Aura路由器检索GET请求时，我们使用如下所示：

// add a route to the map, and a handler for it
$map->get('blog.read', '/blog/{id}', function ($request) {
    $id = (int) $request->getAttribute('id');
    $response = new Zend\Diactoros\Response();
    $response->getBody()->write("You asked for blog entry {$id}.");
    return $response;
});

邮政法怎么样？我尝试了以下代码，但它不能以类似的方式检索名字：

$map->post('profile', '/profile', function ($request) {
    $firstname = $request->getAttribute('firstname');

    $response = new Zend\Diactoros\Response();
    $response->getBody()->write("first name is {$firstname}");
    return $response;
});

输出缺少$firstname值：

first name is

有多种方法可以使用Aura.Dispatcher。下面提供的例子是一种方法。

$route = $matcher->match($request);

因此，一旦您匹配请求，就可以有一个路由或null。

如果有一条路线，你可以得到$route->handler;。这可以是可调用的，也可以是字符串。

是您的实现告诉了如何调用调度程序。来自https://gist.github.com/harikt/8671136

    <?php
require dirname(__DIR__) . '/vendor/autoload.php';

use Aura\Dispatcher\Dispatcher;
use Aura\Router\RouterContainer;
use Zend\Diactoros\Response;
use Zend\Diactoros\ServerRequest;

class Blog
{   
    public function browse(ServerRequest $request)
    {
        $response = new Response();
        $response->getBody()->write("Browse all posts!");

        return $response;
    }

    public function read(ServerRequest $request, $id)
    {
        $id = (int) $request->getAttribute('id');
        $response = new Response();
        $response->getBody()->write("Read blog entry $id");

        return $response;
    }

    public function edit(ServerRequest $request, $id)
    {
        $response = new Response();
        $response->getBody()->write("Edit blog entry $id");

        return $response;
    }
}

$dispatcher = new Dispatcher;
$dispatcher->setObjectParam('controller');
$dispatcher->setMethodParam('action');
$dispatcher->setObject('blog', new Blog());

$routerContainer = new RouterContainer();
$map = $routerContainer->getMap();

// NB : You can use @ sign as in Laravel. So blog@browse
$map->get('blog.browse', '/blog', 'blog::browse');
$map->get('blog.read', '/blog/{id}', 'blog::read');

$request = Zend\Diactoros\ServerRequestFactory::fromGlobals(
    $_SERVER,
    $_GET,
    $_POST,
    $_COOKIE,
    $_FILES
);
$matcher = $routerContainer->getMatcher();
$route = $matcher->match($request);

if ($route) {
    foreach ($route->attributes as $key => $val) {
        $request = $request->withAttribute($key, $val);
    }
    // Take special attention, how I am using the handler.
    // Do what you want with the handler
    list($controller, $action) = explode('::', $route->handler);

    $params = [
        'controller' => $controller,
        'action' => $action,
        'request' => $request,
        // This is not needed, just showing for demo purpose
        'id' => $request->getAttribute('id'),
    ];

    $response = $dispatcher($params);

    // emit the response
    foreach ($response->getHeaders() as $name => $values) {
        foreach ($values as $value) {
            header(sprintf('%s: %s', $name, $value), false);
        }
    }
    http_response_code($response->getStatusCode());
    echo $response->getBody();
} else {
    echo "No route found";
}

我再说一遍这不是唯一的办法。还有其他更好的方法，如果你真的有兴趣了解更多知识，可以阅读内核。

关于你关于从岗位上获得价值的问题。没有别的办法了。路由器不处理POST值。我认为PSR-7可能会在这些领域有所改善:-)。
