<p>实际编程不算很难，主要是理解上出了很多次岔子，上课没有好好听啊。</p>

<li>RotorNum(齿轮编号)</li>
</ol>
<h2 id="加密原理"><a href="#加密原理" class="headerlink" title="加密原理"></a>加密原理</h2><p>先给出3个齿轮的外部状态(明文) 和真正接下来使用的齿轮状态(密文)，共六个字母。用Enigama机在该外部状态下输入密文从而得到对应真正齿轮状态的明文。</p>
<p>接下来用真正齿轮状态(MessageKey)输入密文字符串得到对应明文或输入明文字符串得到密文。</p>
<p>对于输入字母经过以下5个阶段</p>
<ol>
<li>变为接线板对应字母</li>
<li>从右到左经过3个齿轮(根据当前MessageKey得到输出)<ol>
<li>进入齿轮的不是当前变化后的字母，而是Ring Setting后的。即从右往左输入先加delta，从左往右输出减delta。其中delta为当前message-key-ringkey(转子外-内)</li>
<li>当按下某个键位时，对字母加密的是齿轮转了一下的状态</li>
</ol>
</li>
<li>反射板(两两对应字母)</li>
<li>从左到右再经过3个齿轮</li>
<li>变为接线板对应字母</li>
</ol>
<p>对于MessageKey的处理</p>
<ol>
<li>每按键1次转子只转动一次</li>
<li>特殊情况：double stepping: 可能会出现两个或三个齿轮共同旋转</li>
<li>注意RingSetting是固定的</li>

<li>一开始看老师的课件以为反过来从右到左时变为先减Δ，再加Δ，实际还是原来的，不需要考虑变化。</li>
<li>delta就是可以是负数，不需要考虑对26取模</li>

<title>Hexo搭建——关于我踩的坑</title>

<content><![CDATA[<p>第一次搭个人博客，虽然看了不少教程，还是踩了超多的坑。这里总结一下。</p>
<span id="more"></span>
<h2 id="开始搭建"><a href="#开始搭建" class="headerlink" title="开始搭建"></a>开始搭建</h2><p>我选的是Next主题，原因有两个：一是够好看，二是教程够多。</p>
<p>没想到这么多的教程还是翻车搞了整整一晚上加早上。</p>
<h2 id="参考"><a href="#参考" class="headerlink" title="参考"></a>参考</h2><p>总结我踩过的坑，第一恨的就是哪些被搬来搬去从个人网站到博客园再到CSDN的可恶搬运党了。所以说还是要看官方文档。比如搭建还是看<a href="https://hexo.io/zh-cn/docs/index.html">Hexo官方文档</a>，主题配置还是看<a href="https://theme-next.js.org/page/2/">Next主题官方文档</a>。</p>

<title>基于python+selenium+tasksch实现的PTA每日自动打卡</title>
<url>/2021/05/19/%E5%9F%BA%E4%BA%8Epython-selenium-tasksch%E5%AE%9E%E7%8E%B0%E7%9A%84PTA%E6%AF%8F%E6%97%A5%E8%87%AA%E5%8A%A8%E6%89%93%E5%8D%A1/</url>
<content><![CDATA[<p>每次考试周前都要给PTA充钱买卷子，花费甚多，内心不安。为了减少用钻石付费金币的惨剧，写了个PTA自动打卡的程序。</p>
<p>编程语言为python，参考了前辈的代码，利用selenium实现。</p>
<span id="more"></span>
<p>由于签到需要先登录，所以用代码获取登录状态下的cookie后，cookie直接实现登录网页。然后用xpath定位签到按钮，执行一次click，完成签到。</p>
<h2 id="操作"><a href="#操作" class="headerlink" title="操作"></a>操作</h2><h3 id="准备"><a href="#准备" class="headerlink" title="准备"></a>准备</h3><ul>
<li>一台24小时运行的云服务器</li>
<li>对应py脚本</li>
</ul>
<h4 id="Windows系统"><a href="#Windows系统" class="headerlink" title="Windows系统"></a>Windows系统</h4><p>需要先行下载 python 与 selenium，可以使用pip。</p>
<figure class="highlight plain"><table><tr><td class="code"><pre><span class="line">pip install selenium</span><br></pre></td></tr></table></figure>
<p>高版本的 selenium 需要配合 geckodriver 使用，点击<a href="https://github.com/mozilla/geckodriver/releases">这里</a>自行下载对应版本并添加环境变量。</p>
<p>替换py文件中的绝对路径为对应本机的位置。</p>
<p>先运行login.py，设置断点在 <code>dictCookies = driver.get_cookies()</code> 处，在弹出的页面登录，登录成功后继续运行，得到登录cookie。</p>
<p>尝试运行check.py，由于签到按钮只可按动一次，推荐注释掉57行，不注释58行进行验证。</p>
<h4 id="Linux系统"><a href="#Linux系统" class="headerlink" title="Linux系统"></a>Linux系统</h4><p>见<a href="/2021/05/20/Linux%E4%B8%8B%E8%BD%BDselenium-chrome-chrome-driver/" title="Linux下载selenium+chrome+chrome driver">Linux下载selenium+chrome+chrome driver</a>一文</p>
<h3 id="利用-bat-tasksch-自动打卡"><a href="#利用-bat-tasksch-自动打卡" class="headerlink" title="利用 bat+tasksch 自动打卡"></a>利用 bat+tasksch 自动打卡</h3><p>打开记事本，输入并保存为 <code>Run_PTA_Check.bat</code> </p>
<figure class="highlight cmd"><table><tr><td class="code"><pre><span class="line">"python.exe所在路径，如C:\Python39\python.exe" "check.py所在路径，如D:\Code\check.py" </span><br></pre></td></tr></table></figure>
<p>接下来利用windows自带的任务计划程序实现。</p>
<p>win+R，输入taskschd.msc打开任务计划程序</p>

<p>名称随便输入，自己记得就好。触发器设置为每天。操作设置为启动程序。</p>

<p>程序或脚本处输出.bat文件路径，点击下一步并完成。</p>
