PHP为任意页面设访问密码，控制登录 使用方法，把下面的代码存为php文件，下面的整段代码是验证过程，然后在你入口页进行调用例如命名为MkEncrypt.php，那么在入口页进行require_once('MkEncrypt.php');然后设置密码为MkEncrypt('1234');此时密码为1234则密码正确才能进去页面，进入后会存下cookies值，下一次登录的时候则不需要再次输入了代码简介为你的页面支持加密访问，无论什么程序，只要是PHP程序，都是支持这代码的，来实现加密访问你的加密页面或文章等等的页面，不保证其他程序可以正常使用代码如下<?php /******************************************** * 使用方法: * * 1、将本段代码保存为 MkEncrypt.php * * 2、在要加密的页面前面引入这个 php 文件 * require_once('MkEncrypt.php'); * * 3、设置页面访问密码 * MkEncrypt('页面密码'); * ********************************************/ // 密码 Cookie 加密盐 if(!defined('MK_ENCRYPT_SALT')) define('MK_ENCRYPT_SALT', 'Kgs$JC!V'); /** * 设置访问密码 * * @param $password 访问密码 * @param $pageid 页面唯一 ID 值，用于区分同一网站的不同加密页面 */ function MkEncrypt($password, $pageid = 'default') { $pageid = md5($pageid); $md5pw = md5(md5($password).MK_ENCRYPT_SALT); $postpwd = isset($_POST['pagepwd']) ? addslashes(trim($_POST['pagepwd'])) : ''; $cookiepwd = isset($_COOKIE['mk_encrypt_'.$pageid]) ? addslashes(trim($_COOKIE['mk_encrypt_'.$pageid])) : ''; if($cookiepwd == $md5pw) return; // Cookie密码验证正确 if($postpwd == $password) { // 提交的密码正确 setcookie('mk_encrypt_' . $pageid, $md5pw, time() + 3600000, '/'); return; } ?> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <meta charset="UTF-8"> <meta http-equiv="X-UA-Compatible" content="IE=edge"> <meta name="renderer" content="webkit"> <meta name="author" content="mengkun"> <meta name="viewport" content="width=device-width, initial-scale=1.0, minimum-scale=1.0, maximum-scale=1.0, user-scalable=no"> <title>该页面已被加密</title> <style type="text/css"> *{font-family:"Microsoft Yahei",微软雅黑,"Helvetica Neue",Helvetica,"Hiragino Sans GB","WenQuanYi Micro Hei",sans-serif;box-sizing:border-box;margin:0px;padding:0px;font-size:14px;-webkit-transition:.2s;-moz-transition:.2s;-ms-transition:.2s;-o-transition:.2s;transition:.2s} html,body{width:100%;height:100%} body{background-color:#F4F6F9;color:#768093} input,button{font-size:1em;border-radius:3px;-webkit-appearance:none} input{width:100%;padding:5px;box-sizing:border-box;border:1px solid #e5e9ef;background-color:#f4f5f7;resize:vertical} input:focus{background-color:#fff;outline:none} button{border:0;background:#6abd09;color:#fff;cursor:pointer;opacity:1;user-select:none} button:hover,button:focus{opacity:.9} button:active{opacity:1} .main{width:100%;max-width:500px;height:300px;padding:30px;background-color:#fff;border-radius:2px;box-shadow:0 10px 60px 0 rgba(29,29,31,0.09);transition:all .12s ease-out;position:absolute;left:0;top:0;bottom:0;right:0;margin:auto;text-align:center} .alert{width:80px} .mk-side-form{margin-bottom:28px} .mk-side-form input{float:left;padding:2px 10px;width:77%;height:37px;border:1px solid #ebebeb;border-right-color:transparent;border-radius:2px 0 0 2px;line-height:37px} .mk-side-form button{position:relative;overflow:visible;width:23%;height:37px;border-radius:0 2px 2px 0;text-transform:uppercase} .pw-tip{font-weight:normal;font-size:26px;text-align:center;margin:25px auto} #pw-error {color: red;margin-top: 15px;margin-bottom: -20px;} .return-home{text-decoration:none;color:#b1b1b1;font-size:16px} .return-home:hover{color:#1E9FFF;letter-spacing:5px} </style> </head> <body> <div class="main"> <svg class="alert" viewBox="0 0 1084 1024" xmlns="http://www.w3.org/2000/svg" width="80" height="80"> <defs><style/></defs> <path d="M1060.744 895.036L590.547 80.656a55.959 55.959 0 0 0-96.919 0L22.588 896.662a55.959 55.959 0 0 0 48.43 83.907h942.14a55.959 55.959 0 0 0 47.525-85.534zm-470.619-85.172a48.008 48.008 0 1 1-96.015 0v-1.567a48.008 48.008 0 1 1 96.015 0v1.567zm0-175.345a48.008 48.008 0 1 1-96.015 0V379.362a48.008 48.008 0 1 1 96.015 0v255.157z" fill="#FF9800"/> </svg> <form action="" method="post" class="mk-side-form"> <h2 class="pw-tip">该页面已被加密</h2> <input type="password" name="pagepwd" placeholder="请输入访问密码查看" required><button type="submit">提交</button> <?php if($postpwd): ?> <p id="pw-error">Oops!密码不对哦~</p> <script>setTimeout(function() {document.getElementById("pw-error").style.display = "none"}, 2000);</script> <?php endif; ?> </form> <a href="/" class="return-home" title="点击回到网站首页">- 返回首页 - </a> </div> </body> </html> <?php exit(); }转载自：小灯泡设计

利用现有在使用的Typecho主题Joe创建欢迎引导页 Typecho有很多人在使用，利用独立页面功能可以创建有个性的欢迎引导页，首先在主题文件夹内新建一个*.php文件，例如现在本站使用的是Typecho主题Joe，我们可以借用已有的主题内的自定义模板文件，将文件头部代码修改为：<?php /** * 欢迎页 * * @package custom * **/ ?>然后在主题自定义模板文件的与之间的代码修改为下列代码 <link rel="stylesheet" type="text/css" href="./img/style.css"> <div class="content"> <div class="title">小陈之家Chen CYH</div> <hr class="hr"> <div class="discription">盛年不重来，一日难再晨。及时当勉励，岁月不待人。</div> <hr class="hr"> <nav class="cover-navigation cover-navigation--primary"> <ul class="navigation"> <li class="navigation__item"><a href="/archive" target="_self" title="我的文章">浏览</a></li> <li class="navigation__item"><a href="/link.html" target="_blank" title="我的友链">友链</a></li> <li class="navigation__item"><a href="/wallpaper.html" target="_blank" title="我的壁纸">壁纸</a></li> <li class="navigation__item"><a href="/archives.html" target="_blank" title="我的归档">归档</a></li> <li class="navigation__item"><a href="https://yunhe.life/" target="_blank" title="我的相册">相册</a></li> <li class="navigation__item"><a href="/about.html" target="_blank" title="关于站长">关于</a></li> </ul> </nav> <div class="item"> <?php $this->options->JFooter_Left() ?> </div> <?php if ($this->options->JBirthDay) : ?> <div class="item run"> <span>已运行 <strong class="joe_run__day">00</strong> 天 <strong class="joe_run__hour">00</strong> 时 <strong class="joe_run__minute">00</strong> 分 <strong class="joe_run__second">00</strong> 秒</span> </div> <?php endif;

LNMP模式下Nginx如何设置域名301重定向 LNMP下的Nginx如果想将域名lnmp.org 301重定向到www.lnmp.org，同时www.lnmp.org已经添加上，可以按如下步骤修改 使用命令编辑器vi、nano或winscp图形管理软件编辑对应的虚拟主机，一般虚拟主机配置文件位于：/usr/local/nginx/conf/vhost/域名.conf，如添加的域名是www.lnmp.org则配置文件是/usr/local/nginx/conf/vhost/www.lnmp.org.conf在配置文件代码如下：lnmp.org 301跳转到www.lnmp.org示例配置如下：省略www.lnmp.org虚拟主机server配置 server { listen 80; server_name lnmp.org; return 301 http://www.lnmp.org$request_uri; }如果是想让http强制跳转到https，把里面的http换成https就行。http站点301跳转到https站点示例配置如下：server { listen 443 ssl; server_name www.lnmp.org; 省略其他配置 } server { listen 80; server_name lnmp.org; return 301 https://www.lnmp.org$request_uri; }按上面例子修改完成后保存，执行：/etc/init.d/nginx restart 重启nginx，使其生效。该设置不适用于Let'sEncrypt及其他需要http验证的SSL证书；如果使用DNS API方式可以使用这种设置方法。如果是想让https://lnmp.org强制跳转到https://www.lnmp.org可以在https的虚拟主机配置文件中root行或server_name行下面添加上if ($host = 'lnmp.org') { return 301 https://www.lnmp.org$request_uri; }如果要设置对应域名的http跳到对应https站点上如：http://lnmp.org 跳到 https://lnmp.org，http://www.lnmp.org 跳到 https://www.lnmp.org 上。在对应域名的http虚拟主机配置文件中添加：return 301 https://$host$request_uri;如果使用Let'sEncrypt免费SSL证书使用的Let's Encrypt的免费证书且使用http验证方式生成的SSL证书，如果你要想设置301，编辑要设置301域名的nginx虚拟主机配置文件，找到包含有listen 80;的server段，在location ~ /.well-known { allow all; }这几行下面添加，如下配置：location / { return 301 https://$host$request_uri; }保存，如果不设置会导致证书无法正常续期。完整的适用于Let'sEncrypt的301跳转配置文件如下：server { listen 80; #listen [::]:80; server_name lnmp.org www.lnmp.org; index index.html index.htm index.php default.html default.htm default.php; root /home/wwwroot/lnmp.org; location ~ /.well-known { allow all; } location / { return 301 https://$host$request_uri; } }注意：以上所有更改nginx的配置都需要重启ngin生效。来源 © LNMP.org

Markdown基本语法 前言Markdown是一种轻量级标记语言，它允许人们使用易读易写的纯文本格式编写文档，然后转换成有效的XHTML或HTML文档。由于Markdown的轻量化、易读易写特性，并且对于图片，图表、数学式都有支持，目前许多网站都广泛使用Markdown来撰写帮助文档或是用于论坛上发表消息。目前博客主要在本地用Markdown语言写作，然后转移到网站，故粗略了解了一下基本语法。基本语法一、标题在标题文字前加#表示一个#是一级标题，二个#是二级标题，以此类推。支持六级标题。示例：# 这是一级标题 ## 这是二级标题 ### 这是三级标题 #### 这是四级标题 ##### 这是五级标题 ###### 这是六级标题显示效果：这是一级标题这是二级标题这是三级标题这是四级标题这是五级标题这是六级标题二、字体加粗：需要加粗的文字左右两边分别用两个*号包起来斜体：需要倾斜的文字左右两边分别用一个*号包起来斜体加粗：需要倾斜和加粗的文字左右两边分别用三个*号包起来删除线：需要加删除线的文字左右两边分别用两个~~号包起来示例：**这是加粗的文字** *这是倾斜的文字*` ***这是斜体加粗的文字*** ~~这是加删除线的文字~~显示效果：这是加粗的文字这是倾斜的文字`这是斜体加粗的文字这是加删除线的文字三、引用在引用的文字前加>即可。引用也可以嵌套，如加两个>>三个>>>...n个>>>>...示例：>这是引用的内容 >>这也是引用的内容四、分割线三个或者三个以上的 - 或者 * 皆可。示例：--- ---- *** *****显示效果：五、超链接语法：[超链接名](超链接地址 "超链接title") title可加可不加示例：[腾讯视频](https://v.qq.com) [爱奇艺](https://iqiyi.com)显示效果:腾讯视频爱奇艺六、列表语法：无序列表用 - + * 任何一种都可以 - 列表内容 + 列表内容 * 列表内容 注意：- + * 跟内容之间都要有一个空格显示效果：列表内容列表内容列表内容有序列表:语法：1. 列表内容 2. 列表内容 3. 列表内容 注意：数字加点即可，序号跟内容之间要有空格效果如下：列表内容列表内容列表内容七、表格语法：表头|表头|表头 ---|:--:|---: 内容|内容|内容 内容|内容|内容 第二行分割表头和内容。 第二行设置文字属性： 文字默认居左 两边加：表示文字居中 右边加：表示文字居右 注：原生的语法两边都要用 | 包起来。此处省略显示效果：序号姓名关系一唐僧师傅二孙悟空徒弟其它参考 © 小灯泡设计

解决Typecho无法正确显示Gravatar头像 因为某些原因在中国大陆Gravatar头像彻底无法进行访问。由于主题前端一般都可以设置第三方国内镜像源，所以没什么问题。而Typecho后台显示却无法正常加载，很是让人难受。解决方案一修改默认Gravatar头像地址为第三方国内镜像源从网站根目录进入/var/Typecho打开Common.php，找到名为gravatarUrl的function，大概在932行左右，可以用搜索功能查找一下。找到如下所示的代码：if (defined('__TYPECHO_GRAVATAR_PREFIX__')) { $url = __TYPECHO_GRAVATAR_PREFIX__; } else { $url = $isSecure ? 'https://secure.gravatar.com' : 'http://www.gravatar.com'; $url .= '/avatar/'; }修改https://secure.gravatar.com为国内第三方镜像源地址，修改/avatar/为镜像源的文件夹，如此操作后台即可正常显示Gravatar头像。不要忘记https://和文件夹两侧的/以第一个镜像源为例，使用上文所述的方法修改完后的结果为：if (defined('__TYPECHO_GRAVATAR_PREFIX__')) { $url = __TYPECHO_GRAVATAR_PREFIX__; } else { $url = $isSecure ? 'https://sdn.geekzu.org' : 'http://www.gravatar.com'; $url .= '/avatar/'; }解决方案二直接打开Typecho安装目录下的config.inc.php文件，加入以下代码即可（加在任何位置都可）define('__TYPECHO_GRAVATAR_PREFIX__', 'https://sdn.geekzu.org/avatar/');示例推荐第三方国内镜像源：https://sdn.geekzu.org/avatar/ （推荐）https://dn-qiniu-avatar.qbox.me/avatar/https://cdn.v2ex.com/gravatar/https://gravatar.loli.net/avatar/参考自© 呆小萌_Dream
