在 Yii 2.0 的 RESTful APIs 中，view：返回指定资源的详情，HTTP 动词同时支持 GET 与 POST 的实现
1、在 Postman 中 GET 请求指定资源的详情，响应 200，如图1

2、查看路由配置，代码如下
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 | /* 任务管理 */[ 'class' => 'yii\rest\UrlRule', 'controller' => ['v1/plan-task'], 'only' => [ 'log-create', 'index', 'have', 'export', 'have-export', 'create', 'view', 'update', 'claim', 'delete', 'finish', 'transfer', 'video-edit', 'write', 'write-feed', 'commit-article', 'article-review', 'disable', 'upload', 'enable', 'edit' ], 'tokens' => ['{id}' => '<id:\\w[\\w,:;]*>'], 'extraPatterns' => [ 'GET have' => 'have', 'GET export' => 'export', 'GET have-export' => 'have-export', 'PUT claim/{id}' => 'claim', 'PUT finish/{id}' => 'finish', 'POST log/{id}' => 'log-create', 'GET {id}' => 'view', 'GET edit/{id}' => 'edit', 'PUT update' => 'update', 'PUT transfer/{id}' => 'transfer', 'GET video-edit/{id}' => 'video-edit', 'GET write/{id}' => 'write', 'GET write-feed/{id}' => 'write-feed', 'GET commit-article/{id}' => 'commit-article', 'GET article-review/{id}' => 'article-review', 'PUT disable/{id}' => 'disable', 'GET upload/{id}' => 'upload', 'PUT enable/{id}' => 'enable', ],], |
3、查看控制器，代码如下
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 | <?php/** * Created by PhpStorm. * User: Qiang Wang * Date: 2018/05/05 * Time: 11:43 */namespace api\controllers;use yii\rest\ActiveController;class PlanTaskController extends ActiveController{ public $serializer = [ 'class' => 'api\rests\plan_task\Serializer', 'collectionEnvelope' => 'items', ]; /** * @inheritdoc */ public function actions() { $actions = parent::actions(); // 禁用"options"动作 unset($actions['options']); $actions['index']['class'] = 'api\rests\plan_task\IndexAction'; $actions['create']['class'] = 'api\rests\plan_task\CreateAction'; $actions['view']['class'] = 'api\rests\plan_task\ViewAction'; $actions['update']['class'] = 'api\rests\plan_task\UpdateAction'; $actions['delete']['class'] = 'api\rests\plan_task\DeleteAction'; $actions['have'] = [ 'class' => 'api\rests\plan_task\HaveAction', 'modelClass' => $this->modelClass, 'checkAccess' => [$this, 'checkAccess'], ]; $actions['export'] = [ 'class' => 'api\rests\plan_task\ExportAction', 'modelClass' => $this->modelClass, 'checkAccess' => [$this, 'checkAccess'], ]; $actions['have-export'] = [ 'class' => 'api\rests\plan_task\HaveExportAction', 'modelClass' => $this->modelClass, 'checkAccess' => [$this, 'checkAccess'], ]; $actions['edit'] = [ 'class' => 'api\rests\plan_task\EditAction', 'modelClass' => $this->modelClass, 'checkAccess' => [$this, 'checkAccess'], ]; $actions['claim'] = [ 'class' => 'api\rests\plan_task\ClaimAction', 'modelClass' => $this->modelClass, 'checkAccess' => [$this, 'checkAccess'], ]; $actions['finish'] = [ 'class' => 'api\rests\plan_task\FinishAction', 'modelClass' => $this->modelClass, 'checkAccess' => [$this, 'checkAccess'], ]; $actions['transfer'] = [ 'class' => 'api\rests\plan_task\TransferAction', 'modelClass' => $this->modelClass, 'checkAccess' => [$this, 'checkAccess'], ]; $actions['video-edit'] = [ 'class' => 'api\rests\plan_task\VideoEditAction', 'modelClass' => $this->modelClass, 'checkAccess' => [$this, 'checkAccess'], ]; $actions['write'] = [ 'class' => 'api\rests\plan_task\WriteAction', 'modelClass' => $this->modelClass, 'checkAccess' => [$this, 'checkAccess'], ]; $actions['write-feed'] = [ 'class' => 'api\rests\plan_task\WriteFeedAction', 'modelClass' => $this->modelClass, 'checkAccess' => [$this, 'checkAccess'], ]; $actions['commit-article'] = [ 'class' => 'api\rests\plan_task\CommitArticleAction', 'modelClass' => $this->modelClass, 'checkAccess' => [$this, 'checkAccess'], ]; $actions['article-review'] = [ 'class' => 'api\rests\plan_task\ArticleReviewAction', 'modelClass' => $this->modelClass, 'checkAccess' => [$this, 'checkAccess'], ]; $actions['disable'] = [ 'class' => 'api\rests\plan_task\DisableAction', 'modelClass' => $this->modelClass, 'checkAccess' => [$this, 'checkAccess'], ]; $actions['upload'] = [ 'class' => 'api\rests\plan_task\UploadAction', 'modelClass' => $this->modelClass, 'checkAccess' => [$this, 'checkAccess'], ]; $actions['enable'] = [ 'class' => 'api\rests\plan_task\EnableAction', 'modelClass' => $this->modelClass, 'checkAccess' => [$this, 'checkAccess'], ]; $actions['log-create'] = [ 'class' => 'api\rests\plan_task\LogCreateAction', 'modelClass' => $this->modelClass, 'checkAccess' => [$this, 'checkAccess'], ]; $actions['status-count'] = [ 'class' => 'api\rests\plan_task\StatusCountAction', 'modelClass' => $this->modelClass, 'checkAccess' => [$this, 'checkAccess'], ]; return $actions; }} |
4、在 Postman 中 POST 请求指定资源的详情，响应 404，如图2
图2
1 2 3 4 5 6 7 | { "name": "Not Found", "message": "页面未找到。", "code": 0, "status": 404, "type": "yii\\web\\NotFoundHttpException"} |
5、调整路由配置，GET /plan-tasks/79 和 POST /plan-tasks/79：返回资源ID为 79 的详细信息
1 | 'GET,POST {id}' => 'view', |
6、在 Postman 中 POST 请求指定资源的详情，响应 405，不允许的方法。该 URL 仅可以处理以下请求方法：GET，HEAD。如图3
图3
1 2 3 4 5 6 7 | { "name": "Method Not Allowed", "message": "Method Not Allowed. This URL can only handle the following request methods: GET, HEAD.", "code": 0, "status": 405, "type": "yii\\web\\MethodNotAllowedHttpException"} |
7、查看日志，在过滤器 verbFilter：支持 HTTP 方法验证 处验证失败，如图4
图4
1 2 3 4 5 6 7 8 9 10 11 12 | yii\web\MethodNotAllowedHttpException: Method Not Allowed.

8、在控制器中覆盖 yii\rest\ActiveController 的 verbs 方法，添加对于 POST 的支持
1 2 3 4 5 6 7 8 9 | /** * {@inheritdoc} */protected function verbs(){ $verbs = parent::verbs(); $verbs['view'] = ['GET', 'HEAD', 'POST']; return $verbs;} |
9、在 Postman 中 GET 或者 POST 请求指定资源的详情，响应 200，如图5
