1. Prevention of cross-site scripting attacks
Cross-site scripting attacks (referred to as XSS), that is, web applications collect information from users User data. Attackers often inject JavaScript, VBScript, ActiveX, HTML or Flash into vulnerable web applications to confuse visitors and collect visitor information. For example, a poorly designed forum system may display user input without checking. An attacker can inject a piece of malicious JavaScript code into the post content. In this way, when other visitors read this post, these JavaScript codes can be run on the visitor's computer.
One of the most important measures to prevent XSS attacks is: Content inspection before displaying the content entered by the user. For example, you can escape HTML in content. But in some cases this method is not advisable, because this method disables all HTML tags.
Yii integrates HTMLPurifier and provides developers with a very useful component CHtmlPurifier, which encapsulates the HTMLPurifier class. It can remove all malicious code from the audited content through effective review, security and whitelisting functions, and ensure that the content filtered after filtering meets standards.
CHtmlPurifier component can be used as a widget or filter. When used as a widget, CHtmlPurifier can safely filter the content displayed in the view. The following is a code example:
##
<?php $this->beginWidget('CHtmlPurifier'); ?> //...这里显示用户输入的内容... <?php $this->endWidget(); ?>
src address of this image points to a bank website:
http://www.php.cn/. If the user visits this malicious webpage after logging into the bank's website, the user's browser will send an instruction to the bank's website. The content of this instruction may be "transfer 10,000 yuan to the attacker's account." Cross-site attacks take advantage of a specific website that the user trusts, while CSRF attacks, on the contrary, take advantage of the user's specific user identity on a website.
GET The request only allows retrieval of data and cannot modify any data on the server. The
POST request should contain some random values that can be recognized by the server to ensure that the source of the form data and the destination of the running results are the same.
POST. The core of this mechanism is to set a random data in the cookie, and then compare it with the corresponding value in the
POST data submitted by the form.
return array( 'components'=>array( 'request'=>array( 'enableCsrfValidation'=>true, ), ), );
- You can use SSL to create a secure channel and only send the authentication cookie over an HTTPS connection. In this way, the attacker cannot decrypt the cookie sent.
- Set the expiration time of cookies. Do the same for all cookies and seesion tokens. This reduces the chance of being attacked.
- Prevent cross-site code attacks, because it can trigger arbitrary code in the user's browser, and these codes may leak the user's cookies.
- Verify the cookie content when the cookie changes.
return array( 'components'=>array( 'request'=>array( 'enableCookieValidation'=>true, ), ), );
$_COOKIES.
// 检索一个名为$name的cookie值 $cookie=Yii::app()->request->cookies[$name]; $value=$cookie->value; ...... // 设置一个cookie $cookie=new CHttpCookie($name,$value); Yii::app()->request->cookies[$name]=$cookie;

Yii框架是一个高性能、高扩展性、高可维护性的PHP开发框架,在开发Web应用程序时具有很高的效率和可靠性。Yii框架的主要优点在于其独特的特性和开发方法,同时还集成了许多实用的工具和功能。Yii框架的核心概念MVC模式Yii采用了MVC(Model-View-Controller)模式,是一种将应用程序分为三个独立部分的模式,即业务逻辑处理模型、用户界面呈

Yii框架是一个高性能、可扩展、安全的PHP框架。它是一个优秀的开发工具,能够让开发者快速高效地构建复杂的Web应用程序。以下是几个原因,让Yii框架比其他框架更好用。高性能Yii框架使用了一些先进的技术,例如,延迟加载(lazyloading)和自动加载机制(automaticclassloading),这使得Yii框架的性能高于许多其他框架。它还提

随着互联网的快速发展,应用程序对于处理大量并发请求和任务变得越来越重要。在这样的情况下,处理异步任务是必不可少的,因为这可以使应用程序更加高效,并更好地响应用户请求。Yii框架提供了一个方便的队列组件,使得处理异步操作更加容易和高效。在本篇文章中,我们将探讨Yii框架中队列的使用和优势。什么是队列队列是一种数据结构,用于处理数据的先进先出(FIFO)顺序。队

ViewState是ASP.NET中的一种机制,用于保护页面的隐私数据。而在Yii框架中,ViewState同样也是实现页面数据保护的重要手段。在Web开发中,随着用户界面操作的复杂度增加,前端与后端之间的数据传输也愈发频繁。但是,不可避免的会有恶意用户通过网络抓包等手段截获数据。而未加保护的数据可能含有用户隐私、订单信息、财务数据等重要资料。因此,加密传输

Yii是一款优秀的PHP框架,它提供了很多丰富的功能和组件来加快Web应用程序的开发。其中一个非常重要的特性就是可以方便地使用外部库进行扩展。Yii框架中的扩展可以帮助我们快速完成许多常见的任务,例如操作数据库、缓存数据、发送邮件、验证表单等等。但是有时候,我们需要使用一些其他的PHP类库来完成特定的任务,例如调用第三方API、处理图片、生成PDF文件等等。

在现今互联网时代,数据的处理和展示对于各种应用而言都是至关重要的。对于一些数据量较大的网站,其展示效果直接影响用户体验,而优秀的分页机制可以使得数据展示更加清晰,提高用户的使用体验。在本文中,我们将介绍Yii框架中的分页机制,并探讨如何通过优化分页机制来改进数据展示效果。Yii框架是一种基于PHP语言的高性能、适用于Web应用的开发框架。它提供

Yii框架是一款快速、高效、安全的PHP开发框架,依托于丰富的工具和组件,Yii框架可以帮助开发者更轻松地构建高质量的Web应用程序。其中,ORM(对象关系映射)是Yii框架其中之一的特点。这篇文章将简单介绍Yii框架中的ORM,并说明其如何简化数据库操作。一、什么是ORMORM是指对象关系映射,它将面向对象的编程语言中的对象与关系型数据库中的表进行映射,使
