yii2设置网站基础url

 [
        'request' => [
            // !!! insert a secret key in the following (if it is empty) - this is required by cookie validation
            'cookieValidationKey' => '',
            'baseUrl' => 'http://testadmin.website.com/',
        ],
    ],
    'defaultRoute' => 'form-info',
];

if (!YII_ENV_TEST) {
    // configuration adjustments for 'dev' environment
    $config['bootstrap'][] = 'debug';
    $config['modules']['debug'] = [
        'class' => 'yii\debug\Module',
    ];

    $config['bootstrap'][] = 'gii';
    $config['modules']['gii'] = [
        'class' => 'yii\gii\Module',
    ];
}

return $config;

上面的例子是在run/environments/dev/backend/config/main-local.php中设置后台基础url，设置baseurl参数即可，设置前台基础url以此类推
