bugcsshtmlindexphp

时下grunt非常的火啊，用着虽然很爽，但是它的配置确实很烦。如果之前没有用过，想要一下子熟练驾驭它，有一定的学习成本，而且还要装node这个大家伙，项目之初我们选择了compiler.jar这个轻量的工具进行打包。我一直在寻思着，如何编写一键打包工具。之前呢是手工的拼接好有的js文件，做成符合compiler.jar打包文件所要求的批处理文件，然后运行这个批处理，生成我们需要的js和css文件。随着js文件数量的增长，纯手工拼接这些文件的地址就变得非常考验人的耐心了，而且还容易漏掉或重复某些文件，于是“一键打包工具”的编写就变得刻不容缓了。下面是一个真实的index.html文件的一部分：

后面还有很长，bug,活人不能被尿憋死，办法总比问题多。我是会一点php的，php在处理文件方面是很拿手的，是时候让它发挥点作用了。于是我想到了用php去自动提出index里边的js和css，然后按指定的格式生成批处理文件，在后台用静默方式运行这个批处理，最后把结果返回给显示器。这样我就可以坐享其成了。想想都有点小激动哟，于是简单的写了一个界面.

接下来就是实现功能了，先不着急编写代码，分析下需求：

1. 遍历index.html文件，提取js文件或css文件.

2. 对这文件进行过虑，因为有些是注释掉的，有些是调式用的。

3. 生成对应的批处理文件

4. 执行批处理文件

5. 显示处理结果

即然有两种情况，我就用一个工厂模式来适配，方便以后扩展其它类型，目光要放长远一点。即然工厂都有了，那索性再来一个接口,约定都必需要实现“接收请求”和“输出结果”这两个接口。再想想处理js和css都可能会有相同的功能，让它们继承一个父类可以使代码复用，于是继承也先用上。目前的设计应当可以满足我的要求了，于是开始编写php代码.

    </span><span>//</span><span>是否自动执行批处理</span>
    <span>$isAuto</span> = <span>$_POST</span>['zip'] === 'true' ? <span>true</span> : <span>false</span><span>;
    </span><span>//</span><span>处理类型</span>
    <span>$type</span> = <span>$_POST</span>['type'<span>];

    </span><span>$c</span> = Factory::create(<span>$type</span>,<span>$isAuto</span><span>);<br>
    //接口方法

}</span><span>else</span><span>{
    </span><span>echo</span> '请使用静态页访问本程序:<a href="index.html">点此进入</a>'<span>;
}</span>

大致的骨架就出来了。具体的填码过程就比较简单了。稍微有点难度的就是执行批处理这个一方法.

是网上提供的方法，以后可能用的上，这里特意贴一下：

<span>public</span> <span>function</span> runBat(<span>$name</span><span>){
        </span><span>if</span>(!<span>file_exists</span>(<span>$name</span>) || !<span>$this</span>-><span>isAuto){
            </span><span>return</span><span>;
        }
        </span><span>//</span><span>转入后台处理</span>
        @<span>exec</span>(<span>pclose</span>(<span>popen</span>("start /B ". <span>escapeshellcmd</span>(<span>$name</span>), "r"<span>)));
    }</span>

在前面的index.html中，有一个name="noBuild"这个是我人为添加的，这是因为我要过滤这种标识的js文件，这样以后要过滤别的文件，也只要添加这个标识就可以了，不用改php代码。由于是内部使用，没有做表单项来指定工程的路径，默认就是index.html所处的上级目录即为工程目录。这样设计简化了操作，提高了效率。

关于遍历特定的文件，我推荐glob函数，很简洁的方案：

<span>$files</span> = <span>glob</span>(<span>$path</span>.'/*.css',GLOB_NOSORT);

下面是工程目录结构图：

再来一张运行效果图：

最后是处理结果图：

终于不用写grunt的配置和安装node这个家伙了，再也不担心更新的时候，从svn上拉下来一堆node的东西，是时候和它们说再见了：

好像忘了展示前端代码了：

<span>/*</span><span>*
 * 选项卡类
 * @param {string} id 选项卡的ID
 </span><span>*/</span>
<span>function</span><span> Tabs(id){
    </span><span>var</span> node = document.querySelector('#'+<span>id);
    </span><span>var</span> selected = node.querySelector('.selected'<span>);
    </span><span>this</span>.selected =<span> selected;
    </span><span>this</span>.node =<span> node;
    </span><span>this</span><span>.bindEvent();
}

</span><span>/*</span><span>*
 * 切换选项卡
 * @param  {object} event 事件
 * @return {[type]}   [description]
 </span><span>*/</span><span>
Tabs.prototype.change </span>= <span>function</span><span>(event){
    </span><span>var</span> element =<span> event.target;
    </span><span>if</span>(element.tagName.toLowerCase()=='li'<span>){
        </span><span>if</span>(element.className=='selected'<span>){
            </span><span>return</span><span>;
        }
    }</span><span>else</span><span>{
        </span><span>while</span>(element != <span>this</span><span>.node){
            element </span>=<span> element.parentNode;
            </span><span>if</span>(element.tagName.toLowerCase()=='li'<span>){
                </span><span>break</span><span>;
            }
        }
        </span><span>if</span>(element == <span>this</span>.node) <span>return</span><span>;
    }
    </span><span>this</span>.selected.removeAttribute('class'<span>);
    element.className </span>= 'selected'<span>;
    </span><span>this</span>.selected =<span> element;
    </span><span>this</span><span>.content();
}

Tabs.prototype.content </span>= <span>function</span><span>(){
  </span><span>var</span> form =<span> document.form1;

    </span><span>switch</span>(<span>this</span><span>.getTabType()){
      </span><span>case</span> 'js'<span>:
        form.style.display </span>= 'block'<span>;
        form.children[</span>0].innerHTML = '自动压缩JS'<span>;
        </span><span>break</span><span>;
      </span><span>case</span> 'css'<span>:
        form.style.display </span>= 'block'<span>;
        form.children[</span>0].innerHTML = '自动压缩CSS'<span>;
        </span><span>break</span><span>;
      </span><span>default</span><span>:
    }
}</span>

会前端和后端，就是这么任性。轻轻一点，告别烦恼！造自己的工具，让别人去苦逼吧，So easy!

以上就介绍了自己动手，丰衣足食.，包括了方面的内容，希望对PHP教程有兴趣的朋友有所帮助。

绝对会话超时有什么区别？May 03, 2025 am 12:21 AM

绝对会话超时从会话创建时开始计时，闲置会话超时则从用户无操作时开始计时。绝对会话超时适用于需要严格控制会话生命周期的场景，如金融应用；闲置会话超时适合希望用户长时间保持会话活跃的应用，如社交媒体。

如果会话在服务器上不起作用，您将采取什么步骤？May 03, 2025 am 12:19 AM

服务器会话失效可以通过以下步骤解决：1.检查服务器配置，确保会话设置正确。2.验证客户端cookies，确认浏览器支持并正确发送。3.检查会话存储服务，如Redis，确保其正常运行。4.审查应用代码，确保会话逻辑正确。通过这些步骤，可以有效诊断和修复会话问题，提升用户体验。

为会话cookie设置httponly标志的重要性是什么？May 03, 2025 am 12:10 AM

设置httponly标志对会话cookie至关重要，因为它能有效防止XSS攻击，保护用户会话信息。具体来说，1）httponly标志阻止JavaScript访问cookie，2）在PHP和Flask中可以通过setcookie和make_response设置该标志，3）尽管不能防范所有攻击，但应作为整体安全策略的一部分。
