Yii2前后台分开用户表

前台：main.php

    "components" => [
        "user" => [
            "identityClass" => "commonmodelsUser",
            "enableAutoLogin" => true,
"idParam" => "__user",
"identityCookie" => ["name" => "__user_identity", "httpOnly" => true],
"loginUrl" => ["site/login"],
        ],

后台：main.php

    "components" => [
        "user" => [
            "identityClass" => "commonmodelsAdmin",
            "enableAutoLogin" => true,
"idParam" => "__admin",
"identityCookie" => ["name" => "__admin_identity", "httpOnly" => true],
"loginUrl" => ["site/login"],
        ],

前台不变，后台增加LoginFormAdmin.php，Admin.php，验证部分使用$model = new LoginFormAdmin();
