CakePHP中的多个前缀用于API路由

Question

事实证明这比应该的更难。我想做什么：

Router::connect('/:api/:version/:controller/:action/*',
    array(),
    array(
        'api' => 'api',
        'version' => '2.0|2.1'
    )
);

让它映射到控制器动作。例如，有这个：

http://example.com/api/2.0/users/get/1

...在用户控制器中映射到此...

public function api_2_0_get()...

我错过了什么？

Answer 1

您错过了既不支持，也不实际使用前缀路由的事实。您将需要连接每个前缀的路由，例如

Router::connect('/api/2.0/:controller/:action/*',
    array(
        'prefix' => 'api_2_0',
        'api_2_0' => true
    )
);

Router::connect('/api/2.1/:controller/:action/*',
    array(
        'prefix' => 'api_2_1',
        'api_2_1' => true
    )
);

或使用自定义路由类，从多个路由元素构建动作名称，类似于

应用/路由/路由/ VersionedApiRoute.php

App::uses('CakeRoute', 'Routing/Route');

class VersionedApiRoute extends CakeRoute
{
    public function parse($url)
    {
        $route = parent::parse($url);
        if (!$route) {
            return false;
        }

        $route['action'] =
            'api_' . str_replace('.', '_', $route['version']) . '_' . $route['action'];

        return $route;
    }
}

应用/配置/ routes.php文件

App::uses('VersionedApiRoute', 'Routing/Route');

Router::connect('/api/:version/:controller/:action/*',
    array(),
    array(
        'routeClass' => 'VersionedApiRoute',
        'version' => '2\.0|2\.1' // this is a regex, so don't forget to escape the dots
    )
);
