zend框架3中不同api版本的路由路径

Question

这就是我为我的 api 定义路由的方式。它以 /api/v1 为前缀。但是现在 api v2 中添加了一些新模块，并且所有 v1 api 都保持不变并且在 v2 中可用。我如何修改这些路由，以服务于属于 /api/v1 的所有路由，并且当 /api/v1 被调用时，它应该在 /api/v2 被调用时同时服务于 /api/v2 和 /api/v1？

module.config.php

'product' => array(
    'type' => 'Zend\Router\Http\Segment',
    'options' => array(
        'route'    => '/api/v1/categories[/:id]',
        'defaults' => array(
            'controller' => CategoryController::class,
        ),
    ),
),
'products' => array(
    'type' => 'Zend\Router\Http\Segment',
    'options' => array(
        'route'    => '/api/v1/products[/:id]',
        'defaults' => array(
            'controller' => ProductsController::class,
        ),
    ),
),

// ... at lots of v1 apis

//these are introduced in v2
'trends' => array(
    'type' => 'Zend\Router\Http\Segment',
    'options' => array(
        'route'    => '/api/v2/trends[/:id]',
        'defaults' => array(
            'controller' => TrendsController::class,
        ),
    ),
),

Answer 1

您可以将那些常见的 v1 和 v2 移动到单个父路由，并将 v2-only 移动到另一个父路由。下面是可以帮助您理解这个想法的示例（未经测试）代码。

return [
    // in Config.router.routes
    'api' => [
        'child_routes' => [
            'v1' => [
                'child_routes' => [
                    // your API 1-and-2 routes
                    'product' => [/* … */],
                    'products' => [/* … */]
                ],
                'may_terminate' => false,
                'options' => [
                    'constraints' => ['version' => 'v1|v2'],
                    'route'       => '/:version'
                ],
                'type' => Segment::class
            ],
            'v2' => [
                'child_routes' => [
                    // your API 2 routes
                    'trends' => [/* … */]
                ],
                'may_terminate' => false,
                'options' => ['route' => '/v2'],
                'type' => Literal::class
            ]
        ],
        'may_terminate' => false,
        'options' => ['route' => '/api'],
        'type' => Literal::class
    ]
];

如果你不想使用子路由，你可以简单地添加一个路由参数/约束而不是/v1：

return [
    'product' => [
        'options' => [
            'constraints' => [
                'id'      => '…',
                'version' => 'v1|v2'
            ],
            'defaults' => ['controller' => CategoryController::class],
            'route' => '/api/:version/categories[/:id]'
        ],
        'type' => Segment::class
    ]
];

Answer 2

我知道这已经晚了，但我刚刚发现了这个问题。

虽然@gsc 的答案还可以，但这不是正确的答案。

这是正确答案，我也是这样使用的：

            'api' => [
            /** Our main route is /api **/
            'may_terminate' => true, 
            'options' => ['route' => '/api'],
            'type' => Literal::class, 
            'child_routes' => [
                /** Since our main route is /api, this will become /api/v1/YOUR_ACTIONS **/
                'v1' => [
                    'type'    => Segment::class,
                    'options' => [
                        'route'    => '/v1[/:action]',
                        'constraints' => [
                            'action' => '[a-zA-Z][a-zA-Z0-9_-]*',
                        ],
                        'defaults' => [
                            'controller'    => Controller\ApiV1Controller::class,
                            'action'        => 'index',
                        ],
                    ],
                ],
                 /** Since our main route is /api, this will become /api/v2/YOUR_ACTIONS **/
                'v2' => [
                    'type'    => Segment::class,
                    'options' => [
                        'route'    => '/v2[/:action]',
                        'constraints' => [
                            'action' => '[a-zA-Z][a-zA-Z0-9_-]*',
                        ],
                        'defaults' => [
                            'controller'    => Controller\ApiV2Controller::class,
                            'action'        => 'index',
                        ],
                    ],
                ],
                /** Add as many "versions" as you want, all with different controllers. **/
            ],
        ],

这允许您使用控制器的不同“版本”，并且更短、更易于理解且符合标准。

享受吧！
