yii2中用户登录部分

首先：在项目中使用命令

./yii   migrate/create   create_users_table

在项目中的migrations目录中生成相应的创建表的文件

<?php
use yii\db\Schema;
use yii\db\Migration;
use  yii\db\mysql;

class m150225_074041_create_users_table extends Migration
{
    public function up()
    {
        $tableOptions = null;
        if($this->db->driverName=="mysql"){
            $tableOptions="CHARACTER SET utf8 COLLATE utf8_unicode_ci ENGINE=InnoDB";
        }
        $this->createTable("user", [
            'id'=>Schema::TYPE_PK,
            'username'=>Schema::TYPE_STRING." NOT NULL",
            'auth_key'=>Schema::TYPE_STRING."(32) NOT NULL",
            'display_name'=>Schema::TYPE_STRING."(50) NOT NULL",
            "password_hash"=>Schema::TYPE_STRING." NOT NULL",
            "password_reset_token"=>Schema::TYPE_STRING,
            "email"=>Schema::TYPE_STRING,
            "role"=>Schema::TYPE_SMALLINT." NOT NULL DEFAULT 10",
            "status"=>Schema::TYPE_SMALLINT." NOT NULL DEFAULT 10",
            "created_at"=>Schema::TYPE_INTEGER." NOT NULL",
            "updated_at"=>Schema::TYPE_INTEGER." NOT NULL",
        ],$tableOptions);


    }


    public function down()
    {
       
    }
}

然后运行命令：./yii migrate

运行完命令后会在数据库中生成相应的user表。

在models/user.php中的内容如下：

<?php


namespace app\models;


use Yii;
use yii\base\NotSupportedException;
use yii\behaviors\TimestampBehavior;
use yii\db\ActiveRecord;
use yii\web\IdentityInterface;

        $timestamp=(int)end($parts);
        return $timestamp+$expire >= time();
    }
    
    
    public function getId(){
        return $this->getPrimaryKey();
    }
    
    public function getAuthKey(){
