最近需要用到验证码,搜索了很多关于Yii2验证码的切换的介绍,下面我来记录一下,有需要了解Yii2下验证码的切换的朋友可参考。希望此文章对各位有所帮助。

模型代码如下:

<?phpnamespace app/admin/models;use yii;use yii/base/model;use yii/captcha/Captcha;class LoginForm extends Model{  public $verifyCode;  public $password;  public $username;  public function rules(){    return [      ['verifyCode','captcha','captchaAction'=>'/admin/login/captcha','message'=>'{attribute}'],      [['password','username'],'required'],    ];  }}

控制器代码如下:

<?phpnamespace app/admin/controllers;use Yii;use yii/web/Controller;use app/admin/models/LoginForm;use yii/filters/AccessControl;use yii/filters/VerbFilter;use yii/captcha/CaptchaAction;class LoginController extends Controller{ public function actions(){   return [     'captcha'=>'yii/captcha/CaptchaAction',     'maxLength'=>4,     'minLength'=>3,     'width'=>10,     'height'=>10   ];  }  public function actionIndex(){    $log = new LoginForm();         return $this->renderPartial("index",['model'=>$log]);  }  //授权规则}

视图代码如下:

<?phpuse yii/helpers/Html;use yii/bootstrap/Nav;use yii/bootstrap/NavBar;use yii/widgets/Breadcrumbs;use app/assets/AppAsset;use yii/widgets/ActiveFiel;use yii/widgets/ActiveForm;use yii/captcha/Captcha;use app/components/HelloWidget;//url 创建use yii/helpers/Url;AppAsset::register($this);?><?php $this->beginPage()?><!DOCTYPE html><html><head>  <title>博客后台管理系统</title>  <meta charset="utf-8">  <meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1" />  <?=Html::cssFile('@web/css/bootstrap.min.css')?>  <?=Html::cssFile('@web/css/style.css')?>  <?=Html::jsFile("@web/js/jquery-1.11.3.min.js");?>  <?=Html::jsFile("@web/js/bootstrap.min.js");?><?php ?></head>  <?php $this->beginBody()?><body><div class="login-box">  <div class="login">    <div class="login-icon">    </div>    <h4 class="login-title">博客后台管理系统</h4>    <?php $form=ActiveForm::begin(['method'=>'post','action'=> /Yii::$app->urlManager->createUrl('/admin/login/index')])?>      <div class="login-input-box mb10">       <input type="text" class="form-control" name="username" placeholder="用户名">      </div>      <div class="login-input-box mb10">        <input class="form-control" type="password" name="password" placeholder="密码">      </div>      <div class="login-input-box mb30">        <input class="form-control" type="text" name="code" placeholder="验证码">        <span class="login-code">          <img id="code_img" src="<?= Url::toRoute('/admin/login/captcha')?>"        </span>      </div>      <input class="inputbtn bg-success btn-block" type="submit" value="登 录">    <?php ActiveForm::end();?>  </div></div><script type="text/javascript">  //刷新验证码  function get_code(obj)  {    if(!obj)    {      obj = document.getElementById('code_img');    }    obj.src = obj.src + "&t="+Date.parse(new Date());  }</script></body>  <?php $this->beginBody()?></html><?php $this->endPage()?>

这里整个代码差不多了但是要设置一样更重要的 app/vendor/yiisoft/yii2/captcha/的文件下的CaptchaAction.php这文件中修改getVerifyCode($regenerate = false) 的方法$regenerate参数为true (getVerifyCode($regenerate = true))
