Laravel API 中的可选参数 - 请求被错误感知

Question

在我的 api.php 我有这些路线。

我可以请求端点：/api/v2/commodities/1 - 这个请求被重定向到 APICommodityController@read - 没问题！

每当我 GET 请求 /v2/commodities/categories/ 时就会出现问题。我希望将此请求重定向到路由组：'categories'，但 Laravel 将其视为第一组中的可选参数（~ 代码中的 "HERE"评论）。

我该如何解决这个问题？

Route::group( [ 'prefix' => 'v2' ], function() {

    /**
     * Commodity
     */
    Route::group( [ 'prefix' => 'commodities' ], function() {

        /**
         * C: CREATE
         */
        Route::post( '{id?}', 'API\v2\Commodity\APICommodityController@updateOrCreate' );

        /**
         * U: UPDATE
         */
        Route::put( '{id}', 'API\v2\Commodity\APICommodityController@updateOrCreate' );

        /**
         * R: READ (HERE)
         */
        Route::get( '{id?}', 'API\v2\Commodity\APICommodityController@read' );

        /**
         * D: DELETE
         */
        Route::delete( '{id}', 'API\v2\Commodity\APICommodityController@delete' );

        /**
         * Commodity categories
         */
        Route::group( [ 'prefix' => 'categories' ], function() {

            /**
             * C: CREATE
             */
            Route::post( '{id?}', 'API\v2\CommodityCategories\APICommodityCategoriesController@updateOrCreate' );

            /**
             * U: UPDATE
             */
            Route::put( '{id}', 'API\v2\CommodityCategories\APICommodityCategoriesController@updateOrCreate' );

            /**
             * R: READ
             */
            Route::get( '{id?}', 'API\v2\CommodityCategories\APICommodityCategoriesController@read' );

            /**
             * D: DELETE
             */
            Route::delete( '{id}', 'API\v2\CommodityCategories\APICommodityCategoriesController@delete' );

        } );

    } );

Answer 1

在您的 id 参数末尾添加此条件：

->where('id', '[0-9]+')

所以它变成了这个样子:

Route::get( '{id?}', 'API\v2\Commodity\APICommodityController@read' )->where('id', '[0-9]+');

Answer 2

只需将商品类别路线部分移至所有其他路线定义之上即可。这将使 laravel 注册此静态路由而不会被动态路由捕获。

类似的东西：

Route::group( [ 'prefix' => 'v2' ], function() {

    /**
     * Commodity
     */
    Route::group( [ 'prefix' => 'commodities' ], function() {
        /**
         * Commodity categories
         */
        Route::group( [ 'prefix' => 'categories' ], function() {

            /**
             * C: CREATE
             */
            Route::post( '{id?}', 'API\v2\CommodityCategories\APICommodityCategoriesController@updateOrCreate' );

            /**
             * U: UPDATE
             */
            Route::put( '{id}', 'API\v2\CommodityCategories\APICommodityCategoriesController@updateOrCreate' );

            /**
             * R: READ
             */
            Route::get( '{id?}', 'API\v2\CommodityCategories\APICommodityCategoriesController@read' );

            /**
             * D: DELETE
             */
            Route::delete( '{id}', 'API\v2\CommodityCategories\APICommodityCategoriesController@delete' );

        } );

        /**
         * C: CREATE
         */
        Route::post( '{id?}', 'API\v2\Commodity\APICommodityController@updateOrCreate' );

        /**
         * U: UPDATE
         */
        Route::put( '{id}', 'API\v2\Commodity\APICommodityController@updateOrCreate' );

        /**
         * R: READ (HERE)
         */
        Route::get( '{id?}', 'API\v2\Commodity\APICommodityController@read' );

        /**
         * D: DELETE
         */
        Route::delete( '{id}', 'API\v2\Commodity\APICommodityController@delete' );
    } );
