<p>日志文件比较多的时候，博客了设置一些分类标签，能迅速的找到需要的东西，而且看起来比较舒服</p>
<h3 id="下载主题"><a href="#下载主题" class="headerlink" title="下载主题"></a>下载主题</h3><p>进入hexo创建博客的根目录，打开命令行，运行：<br><code>git clone https://github.com/theme-next/hexo-theme-next themes/next</code><br>这个命令就是下载next主题到当前目录themes下</p>
<h3 id="启动主题"><a href="#启动主题" class="headerlink" title="启动主题"></a>启动主题</h3><p>修改配置文件_config.yml<br><code>theme: next</code></p>
<h3 id="主题设定"><a href="#主题设定" class="headerlink" title="主题设定"></a>主题设定</h3><p>修改next/_config.yml,找到Scheme Settings，这里有四种外观<br># Scheme Settings<br>#<br>-————————————————————–</p>
<p># Schemes<br>#scheme: Muse 默认 Scheme，这是 NexT 最初的版本，黑白主调，大量留白<br>#scheme: Mist Muse 的紧凑版本，整洁有序的单栏外观<br>#scheme: Pisces 双栏 Scheme，小家碧玉似的清新<br>#scheme: Gemini 左侧网站信息及目录，块+片段结构布局`<br>想要哪个就把前面的#去掉就行</p>
<h3 id="设置语言"><a href="#设置语言" class="headerlink" title="设置语言"></a>设置语言</h3><p>修改配置文件_config.yml，将language设置成你所需要的语言，例如简体中文：<br>language: zh-Hans</p>
<h3 id="设置菜单"><a href="#设置菜单" class="headerlink" title="设置菜单"></a>设置菜单</h3><p>修改next/_config.yml，找到menu<br>menu:<br> home: / || home<br> #about: /about/ || user<br> #tags: /tags/ || tags<br> #categories: /categories/ || th<br> archives: /archives/ || archive<br> #schedule: /schedule/ || calendar<br> #sitemap: /sitemap.xml || sitemap<br> #commonweal: /404/ || heartbeat<br>这里我们可以设置标签、分类。在这之前需要创建page<br><code>hexo new page 'tags'</code><br><code>hexo new page categories</code><br>在根目录下的source文件会生成tags、categories文件夹<br>分别修改tags和categories文件夹的index.md文件，新增type属性<br>-–<br>title: tags<br>date： 2018-08-08 12：12：12<br>type: tags<br>-–<br>categories的修改类似<br>在新建一篇博的时刻，增加tags和categories属性值，就能在tags和categories界面检索到文章了。</p>
<h4 id="去掉文章后面的标签前面的-号"><a href="#去掉文章后面的标签前面的-号" class="headerlink" title="去掉文章后面的标签前面的#号"></a>去掉文章后面的标签前面的#号</h4><p>修改模板/themes/next/layout/_macro/post.swig，搜索 rel=”tag”>#，将#换成<i class="fa fa-tag"></i></p>
<h4 id="动态背景"><a href="#动态背景" class="headerlink" title="动态背景"></a>动态背景</h4><p>目前NexT主题最新的是V6.0版本，这个版本中可以有4种动态背景：<br>Canvas-nest<br>three_waves<br>canvas_lines<br>canvas_sphere<br>设置方法也很简单，直接设置里需要的动态背景为true。</p>
<h4 id="侧边栏社交小图标设置"><a href="#侧边栏社交小图标设置" class="headerlink" title="侧边栏社交小图标设置"></a>侧边栏社交小图标设置</h4><p>打开主题配置文件_config.yml，搜索social:, ||之后是在图标库中对应的图标。注意空格就行<br>social:<br> #GitHub: <a target="_blank" rel="noopener" href="https://github.com/yourname">https://github.com/yourname</a> || github<br> #E-Mail: mailto:<a href="mailto:yourname@gmail.com">yourname@gmail.com</a> || envelope<br> #Google: <a target="_blank" rel="noopener" href="https://plus.google.com/yourname">https://plus.google.com/yourname</a> || google<br> #Twitter: <a target="_blank" rel="noopener" href="https://twitter.com/yourname">https://twitter.com/yourname</a> || twitter<br> #FB Page: <a target="_blank" rel="noopener" href="https://www.facebook.com/yourname">https://www.facebook.com/yourname</a> || facebook<br> #VK Group: <a target="_blank" rel="noopener" href="https://vk.com/yourname">https://vk.com/yourname</a> || vk<br> #StackOverflow: <a target="_blank" rel="noopener" href="https://stackoverflow.com/yourname">https://stackoverflow.com/yourname</a> || stack-overflow<br> #YouTube: <a target="_blank" rel="noopener" href="https://youtube.com/yourname">https://youtube.com/yourname</a> || youtube<br> #Instagram: <a target="_blank" rel="noopener" href="https://instagram.com/yourname">https://instagram.com/yourname</a> || instagram<br> #Skype: skype:yourname?call|chat || skype<br>去掉前面的#就行<br>可以加上自己的<br> Google: <a target="_blank" rel="noopener" href="http://www.google.cn/">http://www.google.cn/</a> || google<br> Github: <a target="_blank" rel="noopener" href="https://github.com/">https://github.com/</a> || github<br> baidu: <a target="_blank" rel="noopener" href="https://www.baidu.com/">https://www.baidu.com/</a> || baidu<br> Bing: <a target="_blank" rel="noopener" href="https://cn.bing.com/">https://cn.bing.com/</a> || Bing</p>

<h3 id="博客加密"><a href="#博客加密" class="headerlink" title="博客加密"></a>博客加密</h3><p>有时候写一篇博客，不希望每个人都可以看到，可以对博客进行加密，其他人需要输入密码才可以访问这篇博客,百度大多使用js语句实现加密功能，然后那个加密功能有很多bug，包括：</p>
<ul>
<li>search.xml依然保留文章内容，可以使用搜索直接获取文章内容</li>
<li>密码明文传输，直接查看网页源代码即可获取密码（本问题可以采用md5加密解决）</li>
<li>新标签页打开页面不用输入密码即可进入页面（本问题可以使用location定位解决）</li>
<li>源代码未加密，直接下载源代码去掉加密部分即可看到文章内容<br>特别是1,4比较棘手，似乎就没有将网页源码加密以外的方法了。</li>
</ul>
<h3 id="方案"><a href="#方案" class="headerlink" title="方案"></a>方案</h3><p>使用插件hexo-encrypt,地址：<a target="_blank" rel="noopener" href="https://github.com/edolphin-ydf/hexo-encrypt">https://github.com/edolphin-ydf/hexo-encrypt</a></p>
<h3 id="安装"><a href="#安装" class="headerlink" title="安装"></a>安装</h3><p><code>npm install hexo-encrypt --save</code><br>修改博客配置文件_config.yml,在末尾添加：</p>
<figure class="highlight plaintext"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br></pre></td><td class="code"><pre><span class="line">encrypt</span><br><span class="line"> password: 123456</span><br></pre></td></tr></table></figure>
<p>这里123456为默认密码，即若文章加密并且未声明独立密码即可通过默认密码解锁文章。<br>然后在package.json中修改插件的版本号，修改为<br><code>"hexo-encrypt": "^0.2.0"</code></p>
<h3 id="应用"><a href="#应用" class="headerlink" title="应用"></a>应用</h3><p>在每一篇文章的开头加入：</p>
<figure class="highlight plaintext"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br></pre></td><td class="code"><pre><span class="line">encrypt: true</span><br><span class="line">enc_pwd: 123456</span><br></pre></td></tr></table></figure>
<p>这里的enc_pwd为独立密码，设定独立密码后文章不再使用默认密码解锁，改用独立密码解锁。<br>输入<code>hexo s</code> 即可查看效果。<br>注意若修改完插件或密码需要先hexo clean清空缓存。</p>
<h3 id="方案二"><a href="#方案二" class="headerlink" title="方案二"></a>方案二</h3><p>打开/themes/next/layout/_partials/head.swig， 在meta标签后面插入这样一段代码：</p>
<figure class="highlight plaintext"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br><span class="line">4</span><br><span class="line">5</span><br><span class="line">6</span><br><span class="line">7</span><br><span class="line">8</span><br><span class="line">9</span><br><span class="line">10</span><br><span class="line">11</span><br><span class="line">12</span><br><span class="line">13</span><br><span class="line">14</span><br><span class="line">15</span><br></pre></td><td class="code"><pre><span class="line"><script></span><br><span class="line"> (function(){</span><br><span class="line"> if('{{ page.password }}'){</span><br><span class="line"> if (prompt('请输入文章密码') !== '{{ page.password }}'){</span><br><span class="line"> alert('密码错误！');</span><br><span class="line"> history.back();</span><br><span class="line"> }</span><br><span class="line"> }</span><br><span class="line"> })();</span><br><span class="line"></script></span><br><span class="line"></span><br><span class="line">作者：枫頔</span><br><span class="line">链接：https://www.jianshu.com/p/70dbff8d7608</span><br><span class="line">來源：简书</span><br><span class="line">简书著作权归作者所有，任何形式的转载都请联系作者获得授权并注明出处。</span><br></pre></td></tr></table></figure>
<p>然后文章中添加：password: 00000 如下图：<br><a target="_blank" rel="noopener" href="https://www.jianshu.com/p/70dbff8d7608">ref</a><br>如果password后面为空，则表示不用密码。</p>

<h3 id="Queue"><a href="#Queue" class="headerlink" title="Queue"></a>Queue</h3><p>Python的Queue模块中提供了同步的、线程安全的队列类，包括FIFO（先入先出)队列Queue，LIFO（后入先出）队列LifoQueue，和优先级队列PriorityQueue。这些队列都实现了锁原语，能够在多线程中直接使用。可以使用队列来实现线程间的同步。</p>
<p>Queue模块中的常用方法:</p>
<p>Queue.qsize() 返回队列的大小<br>Queue.empty() 如果队列为空，返回True,反之False<br>Queue.full() 如果队列满了，返回True,反之False<br>Queue.full 与 maxsize 大小对应<br>Queue.get([block[, timeout]])获取队列，timeout等待时间<br>Queue.get_nowait() 相当Queue.get(False)<br>Queue.put(item) 写入队列，timeout等待时间<br>Queue.put_nowait(item) 相当Queue.put(item, False)<br>Queue.task_done() 在完成一项工作之后，Queue.task_done()函数向任务已经完成的队列发送一个信号<br>Queue.join() 实际上意味着等到队列为空，再执行别的操作</p>
