PHP框架-yii2(一)

浏览数：42 / 时间：2015年06月09日

yii2的常规安装，使用composer很简单;
与之前对yii1的了解，刚接触的yii2变化之一是命名空间的增加，还有就是有些代码的格式有些变化;

细节笔记：

yii2开发版本基础程序是有注册登陆功能的，字段验证方面较yii1有所进步，可以直接验证某些字段在数据库中是否存在，验证规则如下：

 1 public function rules()
 2     {
 3         return [
 4             [‘username‘, ‘filter‘, ‘filter‘ => ‘trim‘],
 5             [‘username‘, ‘required‘],
 6             [‘username‘, ‘unique‘, ‘targetClass‘ => ‘\common\models\User‘, ‘message‘ => ‘This username has already been taken.‘],//直接判断用户名在数据库中是否存在
 7             [‘username‘, ‘string‘, ‘min‘ => 2, ‘max‘ => 255],
 8 
 9             [‘email‘, ‘filter‘, ‘filter‘ => ‘trim‘],
10             [‘email‘, ‘required‘],
11             [‘email‘, ‘email‘],
12             [‘email‘, ‘unique‘, ‘targetClass‘ => ‘\common\models\User‘, ‘message‘ => ‘This email address has already been taken.‘],//直接判断邮箱在数据库中是否存在
13 
14             [‘password‘, ‘required‘],
15             [‘password‘, ‘string‘, ‘min‘ => 6],
16         ];
17     }

　　2. 表单生成，格式有所变化。代码如下：

 1 <div class="user-register">
 2     <?php $form = ActiveForm::begin([
 3         ‘id‘ => ‘form-register‘,
 4         ‘enableAjaxValidation‘=>true,//是否使用ajax验证
 5         ‘validateOnSubmit‘=>false]//yii1时虽然使用ajax验证但提交时则不是ajax验证，yii2提交时仍是ajax验证，开启此项代表提交不验证
 6     ); ?>
 7         <?= $form->field($model, ‘user_login‘)->textInput() ?>
 8         <?= $form->field($model, ‘user_pass‘)->passwordInput() ?>
 9         <?= $form->field($model, ‘user_nicename‘) ?>
10         <?= $form->field($model, ‘user_email‘) ?>
11         <?= $form->field($model, ‘verifyCode‘)->widget(Captcha::className(), [‘template‘ => ‘<div class="row"><div class="col-lg-2">{input}</div><div class="col-lg-2">{image}</div></div>‘,]) ?>
12         <div class="form-group">
13             <?= Html::submitButton(‘Submit‘, [‘class‘ => ‘btn btn-primary‘]) ?>
14         </div>
15     <?php ActiveForm::end(); ?>
16 </div><!-- user-register -->

　　3.yii2的身份验证使用了新的机制，但是没搞懂怎么弄得，我想覆盖都不知道怎么覆盖，密码的加密方式也没搞懂，

　　4.yii2带了邮箱类，可在main.php的components项中添加配置，代码如下：

//配置代码
‘mailer‘ => [
            ‘class‘ => ‘yii\swiftmailer\Mailer‘,
            ‘transport‘ => [
                ‘class‘ => ‘Swift_SmtpTransport‘,
                ‘host‘ => ‘smtp.163.com‘,
                ‘username‘ => ‘[email protected]‘,
                ‘password‘ => ‘*******‘,
                ‘port‘ => ‘25‘,
                ‘encryption‘ => ‘tls‘,
            ],
            ‘messageConfig‘=>[
                ‘charset‘=>‘UTF-8‘,
                ‘from‘=>[‘[email protected]‘=>‘admin‘]
            ],
 ],

//controller控制器中 代码：
<?php
$mail= Yii::$app->mailer->compose();

$mail->setTo(‘[email protected]‘); 
$mail->setSubject("邮件测试");  
$mail->setTextBody(‘zheshisha ‘);  
$mail->setHtmlBody("问我我我我我");
if($mail->send())  
    echo "success";  
 else  
    echo "failse";   
  die();
