Usage

This extension provides some tools for the secure connection (https) handling.

Filter [[\yii2tech\https\SecureConnectionFilter]] allows automatic redirection from 'http' to 'https' protocol, depending of which one is required by particular action. Actions separation into those requiring secure protocol and the ones requiring unsecure protocol can be setup via secureOnly and secureExcept properties.

Being descendant of [[yii\base\ActionFilter]], [[\yii2tech\https\SecureConnectionFilter]] can be setup both at the controller level and at module (application) level.

Application configuration example:

return [
    'as https' => [
        'class' => 'yii2tech\https\SecureConnectionFilter',
        'secureOnly' => [
            'site/login',
            'site/signup',
        ],
    ],
    // ...
];

Controller configuration example:

use yii\web\Controller;
use yii2tech\https\SecureConnectionFilter;

class SiteController extends Controller
{
    public function behaviors()
    {
        return [
            'https' => [
                'class' => SecureConnectionFilter::className(),
                'secureOnly' => [
                    'login',
                    'signup',
                ],
            ],
        ];
    }

    // ...
}

Heads up! Do not forget about only and except properties of the filter. Keep in mind that secureOnly and secureExcept can not affect those actions, which are excluded from filtering via only and except. You may use this to skip some actions from the secure connection processing.

Heads up! Be aware of the forms, which may appear at on protocol but require submission to the other. Request body can not be transferred during redirect, so submitted data will be lost. You'll have to setup form action manually with the correct schema, instead of relying on the filter.

Automatic URL creation

Using simple redirect from one protocol to another is not efficient and have a risk of loosing data submitted via web form. Thus it is better to explicitly specify URL with correct protocol in your views. You may simplify this process using [[\yii2tech\https\SecureUrlRuleFilter]] action filter. Once applied it will adjust [[\yii\web\UrlManager::rules]] in the way [[\yii\web\UrlManager::createUrl()]] method will automatically create absolute URL with correct protocol in case it miss matches current one.

Application configuration example:

return [
    'as secureUrlRules' => [
        'class' => 'yii2tech\https\SecureUrlRuleFilter',
        'secureOnlyRoutes' => [
            'auth/login',
            'site/signup',
        ],
        'secureExceptRoutes' => [
            'site/index',
            'help/<action>',
        ],
    ],
    'components' => [
        'urlManager' => [
            'enablePrettyUrl' => true,
            'showScriptName' => false,
            'rules' => [
                '/' => 'site/index',
                'login' => 'auth/login',
                'signup' => 'site/signup',
                '<action:contact|faq>' => 'help/<action>',
            ]
        ],
    ],
    // ...
];

Now [[\yii\web\UrlManager::createUrl()]] will create URLs with correct protocol without extra efforts:

if (Yii::$app->request->isSecureConnection) {
    echo Yii::$app->urlManager->createUrl(['site/index']); // outputs: 'http://domain.com/'
    echo Yii::$app->urlManager->createUrl(['auth/login']); // outputs: '/login'
} else {
    echo Yii::$app->urlManager->createUrl(['site/index']); // outputs: '/'
    echo Yii::$app->urlManager->createUrl(['auth/login']); // outputs: 'https://domain.com/login'
}

Note: [[\yii2tech\https\SecureUrlRuleFilter]] filter will take affect only if [[\yii\web\UrlManager::enablePrettyUrl]] is enabled.

Heads up! once applied [[\yii2tech\https\SecureUrlRuleFilter]] filter changes the state of related [[\yii\web\UrlManager]] instance, which may make unexpected side effects. For example: this may break such features as parsing URL.

The more reliable way for automatic URL creation is usage of [[\yii2tech\https\SecureConnectionUrlManagerTrait]]. Being used with the descendant of the [[\yii\web\UrlManager]] it will adjust createUrl() method so it will behave exactly the same as in example above.

Trait usage example:

namespace app\components\web;

use yii2tech\https\SecureConnectionUrlManagerTrait;

class MyUrlManager extends \yii\web\UrlManager
{
    use SecureConnectionUrlManagerTrait;
}

Application configuration example:

return [
    'components' => [
        'urlManager' => [
            'class' => 'app\components\web\MyUrlManager',
            'enablePrettyUrl' => true,
            'showScriptName' => false,
            'rules' => [
                '/' => 'site/index',
                'login' => 'auth/login',
                'signup' => 'site/signup',
                '<action:contact|faq>' => 'help/<action>',
            ],
            'secureOnlyRoutes' => [
                'site/signup',
                'auth/*',
            ],
            'secureExceptRoutes' => [
                'site/index',
                'help/*',
            ],
        ],
    ],
    // ...
];

In case you do not use any custom URL manager in your project you can use [[\yii2tech\https\UrlManager]], which already have [[\yii2tech\https\SecureConnectionUrlManagerTrait]] applied.

Note: usage of [[\yii2tech\https\SecureConnectionUrlManagerTrait]] is more reliable then [[\yii2tech\https\SecureUrlRuleFilter]], but it may consume more computing resources at some cases. Still it is recommended to use trait instead of filter.

Note: [[\yii2tech\https\SecureConnectionUrlManagerTrait]] and [[\yii2tech\https\SecureUrlRuleFilter]] process routes in the different way: filter uses those defined by URL rules, while trait operates exact route names as they passed to createUrl() method.
