yii2 restful api:(原因:CORS头_访问控制允许源__秷丢失)

yii2 rest reactjs

我想使用react with yii2 restful,我创建了这样一个用户控制器:

<?php
namespace app\controllers;
use yii\rest\ActiveController;

class UsersController extends ActiveController
{
    public $modelClass = 'app\models\User';
}

当在浏览器中打开链接时,显示我的用户,当我想使用时 axios 在React中,我得到错误i浏览器控制台:

Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at http://localhost/rest/web/users. (Reason: CORS header âAccess-Control-Allow-Originâ missing).

但是当我检查的时候 network 在Firefox开发工具中,我发现AXIOS请求和IT状态为200,并正确接收响应。

我试着用 behaviors 在我的控制器中运行,如下所示:

public function behaviors()
{
    return [
        'corsFilter' => [
            'class' => \yii\filters\Cors::className(),
            'cors' => [
                'Origin' => ['*'],
                'Access-Control-Request-Method' => ['GET', 'POST', 'PUT', 'PATCH', 'DELETE', 'HEAD', 'OPTIONS'],
                'Access-Control-Request-Headers' => ['*'],
            ],

        ],
    ];
}

但得到错误

无效参数“yii\base\invalidArgumentException Response Content 不能是数组。

我怎么能解决这个问题?

根据 docs 你应该先取消设置 authenticator 筛选以添加 Cors 过滤,所以你的行为应该看起来像

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

    $auth=$behaviors['authenticator'];

    // remove authentication filter necessary because we need to 
    // add CORS filter and it should be added after the CORS
    unset($behaviors['authenticator']);

    // add CORS filter
    $behaviors['corsFilter'] = [
        'class' => '\yii\filters\Cors',
        'cors' => [
            'Origin' => ['*'],
            'Access-Control-Request-Method' => ['GET', 'POST', 'PUT', 'PATCH', 'DELETE', 'HEAD', 'OPTIONS'],
            'Access-Control-Request-Headers' => ['*'],
        ],
    ];

     // re-add authentication filter
    $behaviors['authenticator'] = $auth;

    // avoid authentication on CORS-pre-flight requests (HTTP OPTIONS method)
    $behaviors['authenticator']['except'] = ['options'];
    return $behaviors;
}

通过添加 beforeAction 像下面

public function beforeAction($action)
{
    Yii::$app->response->format = Response::FORMAT_JSON;
    return true;
}
