api - 设置未知属性:yii\web\UrlRule::GET

Question

我有这个错误，我不知道解决。

我用 Yii2 创建了一个 api 端点。几天前端点正在工作，但现在它没有并引发此错误:

message: "Setting unknown property: yii\web\UrlRule::GET index",

"#19 {

有我的 urlManager 配置:

modules' => [
        'v1' => [
            'basePath' => '@app/api/modules/v1', // base path for our module class
            'class' => 'app\api\modules\v1\Api', // Path to module class
        ]
    ]
'components'  => [
        'urlManager'  => [
            'enablePrettyUrl'  => true,
            'showScriptName'  => false,
            'enableStrictParsing' => false,
            'rules' => [
                'class'  => 'yii\rest\UrlRule',
                'controller'  => 'v1/demo',
                'patterns' => [
                    'GET index' => 'index'
                ]
            ],
        ],

我使用 Demo Controller 和一个简单的索引端点创建了这个简单的示例，以显示更清晰的问题。

我怎么解决这个问题？为什么返回未知属性。

如果您需要更多信息，请让我知道，但我现在需要解决这个问题，否则我将成为一个没有返回的疯子。

更新: Controller

这是我的 Controller :

<?php

namespace app\api\modules\v1\controllers;

use yii\rest\Controller;

class DemoController extends Controller
{
    public function behaviors() {
        return [
            [
                'class' => \yii\filters\ContentNegotiator::className(),
                'formats' => [
                    'application/json' => \yii\web\Response::FORMAT_JSON,
                ],
            ],
        ];
    }

    public function actionIndex(){
        return "index ";
    }
}

Yii2 路由指南

我按照关于 Routing 的官方指南做了这些配置:

[
    'class' => 'yii\rest\UrlRule',
    'controller' => 'user',
    'extraPatterns' => [
        'GET search' => 'search',
    ],
]

Answer 1

哇，谢谢你们。我整个周末都在努力解决这个问题，根据您的反馈和研究，我发现配置中有一个小错误。在 Yii2 指南中解释了两段代码中的配置。所以我不得不改变我的代码:

'rules' => [
    'class'  => 'yii\rest\UrlRule',
    'controller'  => 'v1/demo',
    'extraPatterns' => [
        'GET index' => 'index'
   ]
]

对这个:

'rules' => [
    [ // array item
      'class'  => 'yii\rest\UrlRule',
      'controller'  => 'v1/demo',
      'extraPatterns' => [
          'GET index' => 'index'
       ] 
    ]//close the array item
]

嗯，错误消失了。
