yii2框架学习笔记四

yii 验证码使用

1.控制器中配置

public function actions(){
   return [
       'captcha'=>[
           'class'=>'yii\captcha\CaptchaAction',
           'fixedVerifyCode'=>YII_ENV_TEST ? 'testme':null,
       ]
   ]
}

2.在模型中添加验证码的字段
public $verifyCode;
3.添加校验规则

public function rules(){
   return [
       ['verifyCode','captcha']
   ];
}

4.在模板中

<?=$form->filed($model,'verifyCode')->widget(Captcha::className(),[
'template'=>'<div class="row"><div class="col-log-3">{image}</div><div class="col-lg-6">{input}</div></div>'
])?>

yii\db\Query

yii\db\ActiveQuery

$provider=new ActiveDataProvider([
   'query'=>Post::find(),
   'pagination'=>[
       'pagesize'=>20,
   ],
]);

$posts=$provider->getModels();

Array data provider

yii\data\ArrayDataProvider::$allModels()

$sort;
$pagination

sql data provider

yii\data\SQLData

$qury=new Query();

$provider=new ActiveDataProvider([
   'query'=>$query->form('post')->all(),
   'sort'=>[
       'attributes'=>[
           'id','username','email'
       ]
   ],
   pagination=>[
       'pageSize'=>10
   ]
]);

$posts=$provider->getModels();

$count=Yii::$app->db->createCommand('select count(*) from user where status=:status,[':status'=>1]')->queryScalar();

$dataProvider=new SqlDataProvider([
   'sql'=>'select * from user where status=:status',
   'params'=>[':status'=>1],
   'totalCount'=>$count,
   'sort'=>[
       'attributes'=>[
           'age',
           'name'=>[
               'asc'=>['first_name'=>SORT_ASC,'last_name'=>SORT_ASC],
               'desc'=>['first_name'=>SORT_DESC,'last_name'=>SORT_DESC],
               'default'=>SORT_DESC,
               'label'=>'Name',
           ],
       ],
   ],
   'pagination'=>[
       'pageSize'=>20,
   ],
]);

$models=$dataProvider->getModels();

主题部件

'components'=>[
   'view'=>[
       'theme'=>[
           'pathMap'=>['@app/views'=>'@app\themes\basic'],
           'baseUrl'=>'@web/themes/basic',
       ],
   ],
],

用户认证

yii\web\IndentityInterface

class User extends ActiveRecord implents IdentityInterface{
   public static function findIdentity($id){
       return static::findOne($id);
   }
   public static function findIdentityByAccessToken($token,$type=null){
       return static::findOne(['access_token'=>$token]);
   }
   public function getId(){
       return $this->id;
   }
   public function getAuthKey(){
       return $this->auth_key;
   }

   public function validateAuthKey($authKey){
       return $this->getAuthKey()===$authKey;
   }
}

产生独一无二随机的字符串
Yii::$app->getSecurity()->generateRandomString();

public function beforeSave($insert){
   if(parent::beforeSave($insert)){
       if($this->isNewRecord){
           $this->auth_key=Yii::$app->getSecurity()->generateRandomString()
       }
       return true;
   }
   return false;
}

yii密码处理

1.生成伪随机数

bcrypt
crypt

$hash=Yii::$app->getSecurity()->generatePasswrodHash($password);

if(Yii::$app->getSecurity()->avlidatePassword($password,$hash)){

}else{

}

Yii::$app->getSecurity()->generateRandomString();

2.加解密

$encryptedData=Yii::$app->getSecurity()->encrypt($data,$secretKey);
$data=Yii::$app->getSecurity()->decrypty($encryptedData,$secretKey);

3.数据完整性确认

$data=Yii::$app->getSecurity()->hashData($genuineData,$secretKey),
Yii::$app->getSecurity()->validateData($data,$secretKey);

禁用csrf

控制器层

$this->enableCsrfValition

yii框架客户端认证

2.rpc协议

php composer.phar update

nizsheanez/yii2-json-rpc

public function actions(){
   return array(
       'index'=>[
           'class'=>'\nizsheanez\JsonRpc\Action'
       ]
   );
}

$client=new \nizsheanez\JsonRpc\Client('http://url/of/webservice');

$response=$client->someMethod($arg1,$arg2);

yii 缓存

1.片段缓存
<?php
$this->beginCache($id,['duration'=>3600]){
$this->endCache();
}

demo

$dependency=[
'class'=>'yii\caching\DbDependency'，
'sql'=>'select max(update_at) from post',
]

if($this->beginCache($id,['dependency'=>$dependency])){
//在此生成内容
$this->endCache();
}

yii\wigetFragmentCache::dependency;

yii\caching\Dependency

yii\widget\FramentCache::variation

yii\widget\Fragment\Cache::enabled;

<?php

$this->beginCache($id,['duration'=>3600,'variation'=>[yii::$app->language],'enabled'=>Yii::$app->request->isGet]){
//生成缓存

$this->endCache();

}

demo

if($this->beginCache($id1)){
   //在此生成内容
   echo $this->renderDynamic('return Yii::$App->user->identity->name');



   if($this->beginCache($id2,$options2)){
       //在此生成内容
       $this->endCache();
   }
   //在此生成内容
   $this->endCache();
}

2.页面缓存

yii\filters\PageCache

public function behaviors(){
   return[
       'class'=>'yii\filters\PageCache',
       'only'=>['index'],
       'duration'=>40,
       'variations'=>[
           \Yii::$app->language,
       ],
       'dependency'=>[
           'calss'=>'yii\caching\DbDependency',
           'sql'=>'select count(*) from post',
       ]
   ]
}

yii - memache 缓存

1.配置

'components'=>[
   'cache'=>[
       'class'=>'yii\caching\Memcache',
       'servers'=>[
           'host'=>'server1',
           'port'=>11211,
           'weight'=>100,
       ],
       [
           'host'=>'server2',
           'port'=>11211,
           'weight'=>50,
       ]
   ]
]

$data=$cache->get($key);

if($data==false){
$cache->set($key,$data);
}

Memcache
ApcCache
DbCache

get
set
mget
mset
madd
exists
delete
flush

yii\caching\Cache::keyPrefix

$cache->set($key,$data,45);

yii\caching\FileDependency

demo

$dependency=new \yii\caching\FileDependency(['filename'=>'demo.txt']);

$cache->set($key,$data,30,$dependency);

$data=$cache->get($key);

依赖链

yii\caching\ChianedDependency
yii\cachingDbDependency
GroupDependency

yii 使用redis 缓存

yii2-redis

2.使用redis

retrn[
   'components'=>[
       'redis'=>[
           'calss'=>'yii\redis\Connection',
           'hostname'=>'localhost',
           'port'=>6379,
           'database'=>0,
       ],
       'cache'=>[
           ’calss‘=>'yii\redis\Cache'
       ],
       'session'=>[
           'class'=>'yii\redis\Session',
           'redis'=>[
               'hostname'=>'localhost',
               'port'=>6379,
               'database'=>1,
           ]
       ]
   ]
]

使用缓存组建

使用session 组建

yii\redis\ActiveRecord;

attributes()

::primaryKey()

demo

class Student extends \yii\redis\ActiveRecord{
   public function attributes(){

       return ['id','name','address','registration_date'];
   }
   public function getOrders(){
       return $this->hasMany(Order::className(),['customer_id'=>'id']);
   }
   public static function active($query){
       $query->andWhere(['status'=>1]);
   }
}

$customer=new Student();
$customer->attributes=['name'=>'liLy'];
$customer->save();

echo $customer->id;

$customer->Customer::find()->where(['name'=>'test'])->one();
$customer->Customer::find()->active()->all();

restfulurl

1.创建控制器
2.配置url规则

urlManager组建的配置：

'urlManager'=>[
   'enablePrettyUrl'=>true,
   'enableStrictParsing'=>true,
   'showScriptName'=>false,
   'rules'=>[
       ['class'=>'yii\rest\UrlRule','controller'=>'user'],
   ],
]

GET /users:
HEAD /users:
POST /users:
GET /users/234;
HEAD /users/234
PATCH /users/233
DELETE /users/234;
OPTIONS /users/
OPTIONS /users/234

yii\base\Model

public function fields(){
   return[
       'id',
       'email'=>'email_address',
       'name'=>function(){
           return $this->first_name.' '.$this->last_name;
       }
   ]
}

资源
路由

restful api 路由配置 demo

<?php

'urlManager'=>[
   'enablePrettyUrl'=>true,
   'enableStrictParsing'=>true,
   'showScriptName'=>false,
   'rules'=>[
       ['class'=>'yii\rest\UrlRule','controller'=>'user','except'=>['delete','create'],'extraParrerns'=>'['GET search'=>'search']],
   ],

]

[
   'PUT,PATCH users/<id>'=>'user/update',
   'DELETE users/<id>'=>'user/delete',
   'GET,HEAD users/<id>'=>'user/view',
   'POST users'=>'user/create',
   'GET,HEAD users'=>'user/index',
   'users/<id>'=>'user/options',
   'users'=>'user/options',
]

yii\rest\Serializer
yii\filters\ContentNegotiator

curl -i -H "Accept:application/json;q=1.0" "http://locahost/users"

yii\web\JsonResponseFormatter

Http base auth

Oauth 2

yii\filters\RateLimitInterface

getRateLimit()
[100,600]

loadAllowance()
saveAllowance()

X-Rate-Limit-Limit:100
X-Rate-Limit-Remaining
X-Rate-Limit-Reset
