1，增加支持无参数调用Request.QueryString的方式。
直接无参调用 Request.QueryString 会返回Url中?号后面的原始查询字符串。
2，改善了对runt server的script标签的兼容性。标签属性有双引号和无双引号的情况都支持。
3，增加设置选项，在出错时可以输出服务器变量信息。

在CodeIgniter4实现前端切换风格模版功能，并允许风格模版只实现部分页面

一种简单的实现方式是，直接全局切换风格模版目录，这样的缺点是要求新的风格模版必须实现所有页面。
而更优雅的实现方式是：允许风格模版按需实现页面，新的风格模板没有实现的页面自动使用默认模版页面。
]]>
准备给博客系统增加风格模版功能，同时还需要允许新的风格模版按需实现部分页面即可。<br />
<br />
一种简单的实现方式是，直接全局切换风格模版目录，这样的缺点是要求新的风格模版必须实现所有页面。<br />
<br />
而更优雅的实现方式是：允许风格模版按需实现页面，新的风格模板没有实现的页面自动使用默认模版页面。<br />
<br />
<strong>这里介绍两种改造实现的方法：</strong><br />
<h2>1，增加新的全局函数 templateview()</h2><br />
<div class="txt_main"> templateview() 的函数原型和功能对应CodeIgniter4框架自身的函数 view()。<br />
<font color="red">区别就是 templateview 函数会自动处理风格问题。</font><br />
函数代码添加到APP\Common.php中：<br />
<script type="text/javascript">window.attachEvent("onload",function (){AutoSizeDIV('CODE_ztET7VebKhah')})</script><table width="98%" border="0" align="center" cellpadding="0" cellspacing="0" class="code_head"><tr><td></td><td align="right"><a href="javascript:CopyText(document.all.CODE_ztET7VebKhah);">[复制到剪贴板] </a></td></tr></table><div class="code_main" id="CODE_ztET7VebKhah" style="overflow-y:auto;overflow-x:auto;width: 98%;min-height:40px;max-height:500px;"><code><span style="color: #000000"><br />
<span style="color: #007700">function </span><span style="color: #0000BB">templateview</span><span style="color: #007700">(</span><span style="color: #0000BB">$page</span><span style="color: #007700">, </span><span style="color: #0000BB">$data</span><span style="color: #007700">=[], </span><span style="color: #0000BB">$options </span><span style="color: #007700">= []){<br /> return </span><span style="color: #0000BB">currentControl</span><span style="color: #007700">()-></span><span style="color: #0000BB">templateview</span><span style="color: #007700">(</span><span style="color: #0000BB">$page</span><span style="color: #007700">, </span><span style="color: #0000BB">$data</span><span style="color: #007700">, </span><span style="color: #0000BB">$options</span><span style="color: #007700">);<br />} </span><br />
</span><br />
</code></div><br />
这里的全局函数只是提供了一个调用封装，我们会将实际实现添加到BaseController中。<br />
这里用到了在全局函数中访问当前控制器实例的方法，可以参考之前的文章实现 <a target="_blank" href="/blogview/278">CodeIgniter4中如何在view或者helper函数中访问当前控制器对象</a>。<br />
<br />
在BaseController中添加如下实现代码：<br />
<script type="text/javascript">window.attachEvent("onload",function (){AutoSizeDIV('CODE_DUHCw6KCWg7K')})</script><table width="98%" border="0" align="center" cellpadding="0" cellspacing="0" class="code_head"><tr><td></td><td align="right"><a href="javascript:CopyText(document.all.CODE_DUHCw6KCWg7K);">[复制到剪贴板] </a></td></tr></table><div class="code_main" id="CODE_DUHCw6KCWg7K" style="overflow-y:auto;overflow-x:auto;width: 98%;min-height:40px;max-height:500px;"><code><span style="color: #000000"><br />

</span><br />
</code></div><br />
<br />
这样主要工作就算完成了。<br />
其它需要调整的地方<br />
<ol type="1"><br />
<li>在Controller的初始化代码中给 $this->template 属性赋值。<br />
<li>控制器中调用 view() 函数的地方，如果需要使用风格模版功能，改为调用 $this->templateview()函数或者全局函数 templateview()<br />
<li>在视图文件中如果调用其它视图的地方如<?=view('header')?> 改为 <?=templateview('header')?><br />
</ul></ol><br />
</div><br />
<br />
<h2>第二种实现方式</h2><br />
<div class="txt_main">直接替换框架的 view() 函数。<br />
函数代码添加到APP\Common.php中完成函数替换：<br />
<script type="text/javascript">window.attachEvent("onload",function (){AutoSizeDIV('CODE_foDW8rtyfMOz')})</script><table width="98%" border="0" align="center" cellpadding="0" cellspacing="0" class="code_head"><tr><td></td><td align="right"><a href="javascript:CopyText(document.all.CODE_foDW8rtyfMOz);">[复制到剪贴板] </a></td></tr></table><div class="code_main" id="CODE_foDW8rtyfMOz" style="overflow-y:auto;overflow-x:auto;width: 98%;min-height:40px;max-height:500px;"><code><span style="color: #000000"><br />

</span><br />
</code></div><br />
<br />
再就是BaseController中代码，和第一部分的代码基本一样，只有templateview函数代码不同，新的代码参考如下<br />

使用安全的方式实现用户登录，并在Cookie中保存登录状态，记住我（remember me）功能。<br />
<br />
比较天真的实现方式：将登录凭证、权限信息等保存到Cookie中。<br />
真的是很可怕，本站之前使用的老ASP博客系统就是这么实现的。<br />
最终导致系统被黑，网站被挂马。。。。。<br />
<br />
这次开发的新系统考虑到这种教训，采用了比较安全的实现方式。<br />
<br />
<h2>1，在用户密码的存储和验证方面使用了安全性较高的实现方案。</h2><br />
<div class="txt_main"> 具体实现方式在之前的文章中有详细介绍。<br />
a. 对密码强度进行要求。 参考 <a target="_blank" href="/blogview/275"> 简单实现js密码强度检测，友好的html css样式提示 </a><br />
<font color="red">密码要求至少8位，大小写字母数字标点符合至少包含三种。</font><br />
保证密码的基本安全性。<br />
<br />
b. 对密码采用安全的hash加密存储。参考 <a target="_blank" href="/blogview/276">在PHP程序中实现安全的用户密码保存-加密存储和登录验证</a><br />
密码安全存储是为了应对数据泄漏风险。<br />
</div><br />
<br />
<h2>2，在登录时进行暴力破解预防</h2><br />
<div class="txt_main">最基本的两项就是 验证码 和 密码试错次数限制。<br />
验证码功能可以参考之前的文章 <a target="_blank" href="/blogview/280">在CodeIgniter4中集成谷歌验证码 reCaptcha V2 </a><br />
<br />
关于密码错误次数的限制，网上有一些天真的利用 Session 记录错误次数的实现代码。<br />
那样是完全没有效果的。<br />
<br />

CodeIgniter4有缓存模块，我们这里可以直接利用它自带的缓存模块实现<br />

</code></div><br />
根据用户名来记录密码错误次数信息，在登录时先判断错误次数。次数超过时直接报错。<br />
然后进行登录验证，密码失败时，调用辅助函数记录次数。<br />
</div><br />
<br />
<h2>3，安全的使用Cookie保存登录状态</h2><br />
<div class="txt_main">首先，绝对不能将用户凭证权限等信息保存到Cookie中。<br />
我们可以在Cookie中保存一个没有实际意义token标识。同时将这个token标识，过期信息保存到数据库中和用户关联。<br />

</span><br />
</code></div><br />
在用户登录成功后通过上面的辅助函数生成一个随机token。<br />
<br />
在用户下次访问时直接获取token值，然后从数据库中查询是否有关联用户。<br />
如果找到用户，先判断是否过期，然后实现自动登录，并从数据库中获取用户权限等信息。<br />
<br />
如果考虑更严格安全一点，也可以在数据库中记录用户的IP地址，UserAgent等信息，要求完全匹配才给登录。<br />
</div><br />
<br />
<h2>4，自动登录Token的注销</h2><br />
<div class="txt_main">在用户进行密码修改后要主动从数据中删除token值，避免安全漏洞。<br />
<br />
在用户 点击 退出登录 后，也要主动注销token值，同时注销Session。<br />
这一点很重要，可以保证用户在公共场合登录帐号后能安全退出。<br />
在用户退出后不会给Cookie劫持或者Session劫持攻击机会。<br />
</div><br />
<br />
<h2>5，最后，敏感操作要重新验证用户密码</h2><br />
<div class="txt_main">如用户修改密码、邮箱、绑定手机号等情况，需要重新验证用户，以保证安全。<br />

通过验证码可以防止一些机器人和程序自动化的操作，如发送垃圾信息等。
验证码还可以防止暴力破解攻击，特别是在登录或密码重置等敏感操作时。
通过添加验证码，也可以增加攻击的难度和时间，从而减少攻击成功的可能性。

为什么要在网站上使用验证吗？主要还是安全方面的原因。<br />
通过验证码可以防止一些机器人和程序自动化的操作，如发送垃圾信息等。<br />
验证码还可以防止暴力破解攻击，特别是在登录或密码重置等敏感操作时。<br />
通过添加验证码，也可以增加攻击的难度和时间，从而减少攻击成功的可能性。<br />
<br />
国内大厂的验证码都是收费的，之前腾讯有免费的防水墙（验证码）服务，现在也停了。<br />
国际大厂免费的验证码服务，谷歌算是比较有名气的了。<br />
<br />
我们这边选择的是 reCaptcha V2 版本的。<br />
在系统集成之前，你需要先去谷歌官网申请 reCaptcha 的帐号密钥。<br />
因为网络因素，这个是无法直接访问的，请大家参考网上的申请教程。<br />
我们这里只介绍在CodeIgniter4系统中集成的方法。<br />
<br />
<h2>首先，在 App\Config\App.php 中增加 密钥的配置设置。</h2><br />
<div class="txt_main">/**<br />
* 谷歌验证码配置<br />
* reCaptcha V2<br />
*/<br />
public $reCaptchaV2 = ['htmlkey' => "***这里是网页端的密钥======",<br />
"apikey" => "=======这里是后端api的密钥=====" <br />
];</div><br />
<br />
<h2>然后，增加两个辅助函数，辅助函数可以写到 App\Common.php 中。</h2><br />
<div class="txt_main">第一个辅助函数，是在网页中显示验证码组件。<br />
注意这里引用的js脚本路径，这个路径是可以在国内正常使用的。<br />

<br />
<strong>然后通过服务配置文件，将我们扩展的核心类注册到系统中</strong><br />
<div class="txt_main">需要修改的文件是 App\Config\Services.php<br />
在文件中添加如下函数，完成注册：<br />
<script type="text/javascript">window.attachEvent("onload",function (){AutoSizeDIV('CODE_hJGliRpoPW85')})</script><table width="98%" border="0" align="center" cellpadding="0" cellspacing="0" class="code_head"><tr><td></td><td align="right"><a href="javascript:CopyText(document.all.CODE_hJGliRpoPW85);">[复制到剪贴板] </a></td></tr></table><div class="code_main" id="CODE_hJGliRpoPW85" style="overflow-y:auto;overflow-x:auto;width: 98%;min-height:40px;max-height:500px;"><code><span style="color: #000000"><br />

</div><br />
<br />
<strong>最后是访问方式</strong><br />
<div class="txt_main">首先在 app\Common.php 中添加全局的辅助函数：<br />
<script type="text/javascript">window.attachEvent("onload",function (){AutoSizeDIV('CODE_0bv5VXDv5LkT')})</script><table width="98%" border="0" align="center" cellpadding="0" cellspacing="0" class="code_head"><tr><td></td><td align="right"><a href="javascript:CopyText(document.all.CODE_0bv5VXDv5LkT);">[复制到剪贴板] </a></td></tr></table><div class="code_main" id="CODE_0bv5VXDv5LkT" style="overflow-y:auto;overflow-x:auto;width: 98%;min-height:40px;max-height:500px;"><code><span style="color: #000000"><br />
<span style="color: #FF8000">/**<br /> * 获取当前的控制器实例<br /> */ <br /></span><span style="color: #007700">function </span><span style="color: #0000BB">currentControl</span><span style="color: #007700">(){<br /> </span><span style="color: #0000BB">$app </span><span style="color: #007700">= </span><span style="color: #0000BB">Config\Services</span><span style="color: #007700">::</span><span style="color: #0000BB">codeigniter</span><span style="color: #007700">();<br /> return </span><span style="color: #0000BB">$app</span><span style="color: #007700">-></span><span style="color: #0000BB">getCurrentControl</span><span style="color: #007700">();<br />} </span><br />
</span><br />
</code></div><br />
<br />
<strong>然后你就可以通过全局函数 <font color="red">currentControl</font> 在任意位置访问当前控制器实例了。</strong><br />

在PHP程序中实现安全的用户密码保存-加密存储和登录验证

在网络世界中，用户密码的安全问题日益受到关注，用户身份验证和密码保护变得愈发重要。
不用说明码保存密码这种低级问题，从2004年MD5碰撞漏洞以来在系统中使用md5保存密码都是不可以想象的灾难。
采用md5、sha1甚至是加盐的md5、sha256都已经是不安全的了
目前有四种仍然安全的密码哈希算法：
- Argon2
- bcrypt
- scrypt
- PBKDF2

<div class="txt_main">在网络世界中，用户密码的安全问题日益受到关注，用户身份验证和密码保护变得愈发重要。<br />
不用说明码保存密码这种低级问题，从2004年MD5碰撞漏洞以来在系统中使用md5保存密码都是不可以想象的灾难。<br />
<strong>采用md5、sha1甚至是加盐的md5、sha256都已经是不安全的了</strong><br />
目前有四种仍然安全的密码哈希算法：<strong><br />
<ul><li> Argon2 <li> bcrypt <li> scrypt <li> PBKDF2 </ul></ol></strong></div><br />
<br />
<div class="txt_main">一些PHP系统的生成环境可以没有安装PECL包，这种情况下 scrypt 哈希加密算法 就无法使用。<br />
如果可能的话建议优先使用 scrypt 哈希加密算法。<br />
<br />
除此之外我们建议优先使用 bcrypt，更重要的是PHP提供了内置函数支持。<br />
我们可以直接使用<strong><font color="red"> password_hash()</font> 和 <font color="red"> password_verify() </font></strong><br />
<br />
<strong>使用bcrypt需要注意它的两点限制：</strong><br />
<ol type="1"><li>它最多只支持72个字符，超过的字符会被截断。<li>如果字符串中含有NUL（\0）字符时会被截断</ul></ol><br />
<br />
<strong>对于一般网站来说这都不是问题，用户密码通常不会超过72个字符。<br />
网页端输入也不可能会出现NUL（\0）字符。</strong><br />
</div><br />
<br />
<h2>实际实现代码</h2><br />

<strong>js代码</strong><br />
下面是简单的实现逻辑，主要检测密码长度，字符种类数。<br />
要求：大写字母、小写字母、标点符合、数字至少包含三种。密码不少于8个字符。<br />
强度值达到 3 即可满足条件。<br />
代码依赖jQuery。<br />
<br />
如果需要更复杂的密码强度检测，可以使用开源js库 zxcvbn 【 dropbox 开发的一个JavaScript密码强度估算库】。<br />
