 [

            'username' => 'admin',  
            'password' => 'admin',  
            'authKey' => 'test100key',

                return new static($user);  
            }  
        }  
  
        return null;

    }  
  
    /**

    public function validateAuthKey($authKey)  
    {  
        return $this->authKey === $authKey;  
    }  
  
    /** 
     * Validates password 
     * 
     * @param  string  $password password to validate 
     * @return boolean if password provided is valid for current user 
     */  
    public function validatePassword($password)  
    {  
        return $this->password === $password;  
    }  
}

改为如下代码即可

Php代码

get('db_admin');  
    }  
  
    /** 
     * Finds user by username 
     * 
     * @param  string      $username

    {  
    $user = User::find()->where(['username'=>$username])->asArray()->one();  
    if(isset($user)){  
            $user['authKey'] = self::$AUTH_KEY;  
            $user['accessToken'] = self::$ACCESS_TOKEN;  
    }  
    return isset($user) ? new static($user) : null;  
    }  
  
    /**
