搭建yii2框架时,最后一步运行php yii serve.

然后访问localhost:8080,然后就开始报错:

yii\web\Request::cookieValidationKey must be configured with a secret key.

1.解决办法

打开我们yii2框的目录,找到config/web.php。然后找到下面代码:

        'request' => [
            // !!! insert a secret key in the following (if it is empty) - this is required by cookie validation
            'cookieValidationKey' => '123456',
        ],

原来cookieValidationKey的值是空,给他改成一个非空值就可以,我测试过true,123456,asdf等字符串,均能正常打开页面,

正常打开网站是下面这样:
