yii2 的 restful api 路由实例

yii\rest\UrlRule

使用yii\rest\UrlRule来自动映射控制器的 restful 路由，简单快捷，缺点是必须得按规定好的方法名去写业务。

映射的规则如下，当然，你可以修改源码为你的习惯：

public $patterns = [
    'PUT,PATCH {id}' => 'update',
    'DELETE {id}' => 'delete',
    'GET,HEAD {id}' => 'view',
    'POST' => 'create',
    'GET,HEAD' => 'index',
    '{id}' => 'options',
    '' => 'options',
];

除了被限制了HTTP动词对应的方法名外，其他都很好用，比如pluralize是多么的优雅啊，可以自动解析单词的复数，laravel的话要一个个的去写，反而有些不方便了

'urlManager'   => [
    'enablePrettyUrl'     => true,
    'showScriptName'      => false,
    'enableStrictParsing' => true,
    'rules'               => [
        [
            'class'      => 'yii\rest\UrlRule',
            'controller' => [
                'v1/user',
                'v1/news',
                'routeAlias' => 'v1/box'
            ],
            'pluralize'  => true
        ],
    ]
]

自定义路由

注意我路由里很刻意的用了复数模式，但很鸡肋，因为一些单词的复数并不是简单的加个 s 就可以了。

'urlManager'   => [
    'enablePrettyUrl'     => true,
    'showScriptName'      => false,
    'enableStrictParsing' => true,
    'rules'               => [
        // 利用 module 做个版本号也是可以的
        'GET <module:(v1|v2)>/<controller:\w+>s'                 => '<module>/<controller>/index',
        'GET <module:(v1|v2)>/<controller:\w+>s/<uid:\d+>'       => '<module>/<controller>/view',
        'POST <module:(v1|v2)>/<controller:\w+>s'                => '<module>/<controller>/create',
        'PUT,PATCH <module:(v1|v2)>/<controller:\w+>s/<uid:\d+>' => '<module>/<controller>/update',
        'DELETE <module:(v1|v2)>/<controller:\w+>s/<uid:\d+>'    => '<module>/<controller>/delete',
        'OPTIONS <module:(v1|v2)>/<controller:\w+>s'             => '<module>/<controller>/options',

        '<controller:\w+>/<action:\w+>'              => '<controller>/<action>',// normal
        '<module:\w+>/<controller:\w+>/<action:\w+>' => '<module>/<controller>/<action>',// module
        '/'                                          => 'site/default',// default route
    ]
]

当然，这种高度动态的路由也可以写的像laravel一样半静态。

'GET v1/children'                 => 'v1/child/index',
'GET v1/children/<uid:\d+>'       => 'v1/child/view',
'POST v1/children'                => 'v1/child/create',
'PUT,PATCH v1/children/<uid:\d+>' => 'v1/child/update',
'DELETE v1/children/<uid:\d+>'    => 'v1/child/delete',
'OPTIONS v1/children'             => 'v1/child/options',

如同laravel的如下

Route::get("/v1/children", "ChildController@index");
Route::post("/v1/children", "ChildController@create");
Route::put("/v1/children/{uid}", "ChildController@update");
Route::patch("/v1/children/{uid}", "ChildController@update");
Route::delete("/v1/children/{uid}", "ChildController@delete");
Route::options("/v1/children", "ChildController@options");
