Php Yii2 Rest api put方法返回内部服务器错误-由于未知原因无法更新对象

我正在用yii2创建一个API，除了

put

方法之外，所有方法都可以正常工作。在保存之前，我在

方法中获取数据，但在保存时得到以下错误

{“名称”：“内部服务器错误”，“消息”：“更新失败”
对象因未知原因被删除。“，“代码”：0，“状态”：500，

“类型”：“yii\web\ServerErrorHttpException”}

这是我的控制器文件

ProductsController.php

<?php

namespace app\controllers;

use yii\rest\ActiveController;
use yii\filters\auth\HttpBearerAuth;


class ProductsController extends ActiveController {

    public $modelClass = 'app\models\Product';

    public function __construct($id, $module, $config = array()) {

        parent::__construct($id, $module, $config);
    }


    public function behaviors() {
        $behaviors = parent::behaviors();

        $behaviors['authenticator'] = [
            'class' => HttpBearerAuth::className(),
        ];

        return $behaviors;
    }

}

我最近也遇到了同样的问题，解决办法是数据传递不正确。通常它应该作为json传递

namespace app\controllers;

use yii\rest\ActiveController;
use yii\filters\auth\HttpBearerAuth;
use yii\filters\VerbFilter;
use yii\web\Response;
use yii\helpers\ArrayHelper;
class ProductsController extends ActiveController {

    public $modelClass = 'app\models\Product';

    public function __construct($id, $module, $config = array()) {

        parent::__construct($id, $module, $config);
    }

    public function behaviors() {
        return ArrayHelper::merge(parent::behaviors(), [
                    [
                        'class' => HttpBearerAuth::className(),
                        'only' => ['index', 'view', 'create', 'update', 'search'],
                    //     'formats' => ['application/json' => Response::FORMAT_JSON,],
                    ],
                    'verbs' => [
                        'class' => VerbFilter::className(),
                        'actions' => [
                            'index' => ['get'],
                            'view' => ['get'],
                            'create' => ['post'],
                            'update' => ['PUT'],
                            'delete' => ['delete'],
                            'deleteall' => ['post'],
                            'search' => ['get']
                        ],
                    ]
        ]);
    }

尝试在
json

{
    "name": "product name"

}

namespace app\controllers;

use yii\rest\ActiveController;
use yii\filters\auth\HttpBearerAuth;
use yii\filters\VerbFilter;
use yii\web\Response;
use yii\helpers\ArrayHelper;
class ProductsController extends ActiveController {

    public $modelClass = 'app\models\Product';

    public function __construct($id, $module, $config = array()) {

        parent::__construct($id, $module, $config);
    }

    public function behaviors() {
        return ArrayHelper::merge(parent::behaviors(), [
                    [
                        'class' => HttpBearerAuth::className(),
                        'only' => ['index', 'view', 'create', 'update', 'search'],
                    //     'formats' => ['application/json' => Response::FORMAT_JSON,],
                    ],
                    'verbs' => [
                        'class' => VerbFilter::className(),
                        'actions' => [
                            'index' => ['get'],
                            'view' => ['get'],
                            'create' => ['post'],
                            'update' => ['PUT'],
                            'delete' => ['delete'],
                            'deleteall' => ['post'],
                            'search' => ['get']
                        ],
                    ]
        ]);
    }

{
    "name": "product name"

}
