 17 | ## 1. 平台简介
 18 | 
 19 | “阅后即焚”平台的核心功能是允许用户创建临时的文本内容，并在设定条件满足后销毁这些内容。用户可以通过时间或最大访问次数来控制内容的存活时间。该平台还支持对内容设置访问密码以增强隐私性。
 20 | 平台的功能流程分为三部分：
 21 | 
 22 | 1. 前端提交内容和设置条件
 23 | 2. 后端保存内容并处理销毁逻辑
 24 | 3. 查看内容和执行销毁
 25 | 
 26 | ## 2. 前端页面分析
 27 | 
 28 | 前端主要负责内容提交的表单展示、与用户的交互以及结果展示。
 29 | 
 30 | ### 2.1 页面结构
 31 | 
 32 | 前端代码中使用了HTML5、Bootstrap和jQuery库来实现响应式布局和交互功能。页面包括了一个简单的导航栏、内容提交表单、结果展示区域，以及一个固定的页脚。
 33 | 主要代码：
 34 | 
 35 | ```html
 36 | <form id="pasteForm">
 37 |     <div class="form-group">
 38 |         <label for="content">内容</label>
 39 |         <textarea class="form-control" id="content" name="content" rows="5" required></textarea>
 40 |     </div>
 41 |     <div class="form-group">
 42 |         <label for="password">密码（可选）</label>
 43 |         <input type="text" class="form-control" id="password" name="password">
 44 |     </div>
 45 |     <div class="form-group">
 46 |         <label>过期设置</label>
 47 |         <div class="form-row">
 48 |             <div class="col-md-6">
 49 |                 <div class="form-check">
 50 |                     <input class="form-check-input" type="radio" name="expire_condition" value="time" id="expireConditionTime" checked>
 51 |                     <label class="form-check-label" for="expireConditionTime">销毁时间（分钟）</label>
 52 |                     <input type="number" name="expiration_minutes" class="form-control mt-2" placeholder="例如: 60">
 53 |                 </div>
 54 |             </div>
 55 |             <div class="col-md-6">
 56 |                 <div class="form-check">
 57 |                     <input class="form-check-input" type="radio" name="expire_condition" value="views" id="expireConditionViews">
 58 |                     <label class="form-check-label" for="expireConditionViews">最大访问次数</label>
 59 |                     <input type="number" name="max_views" class="form-control mt-2" placeholder="例如: 10">
 60 |                 </div>
 61 |             </div>
 62 |         </div>
 63 |     </div>
 64 |     <div class="form-group">
 65 |         <button type="submit" class="btn btn-primary">创建</button>
 66 |     </div>
 67 | </form>
 68 | ```
 69 | 
 70 | ### 2.2 交互逻辑
 71 | 
 72 | 使用jQuery进行AJAX请求，将表单数据提交到后端的`create_paste.php`。前端的表单提交事件被拦截，通过AJAX发送请求并处理返回的结果。
 73 | 
 74 | ```javascript
 75 | $('#pasteForm').submit(function(e) {
 76 |     e.preventDefault();
 77 | 
 78 |     $.ajax({
 79 |         type: 'POST',
 80 |         url: 'create_paste.php',
 81 |         data: $(this).serialize(),
 82 |         success: function(response) {
 83 |             // 成功后处理响应数据
 84 |         }
 85 |     });
 86 | });
 87 | ```
 88 | 
 89 | 前端会根据后端返回的结果（如创建成功与否）动态显示内容，并且支持一键复制功能。
 90 | 
 91 | ## 3. 后端逻辑分析
 92 | 
 93 | 后端代码使用PHP和MySQL数据库进行内容的保存和验证。主要功能包括：
 94 | 
 95 | 1. 验证并保存用户输入的内容。
 96 | 2. 根据设定的条件（时间或访问次数）销毁内容。
 97 | 3. 对内容进行访问控制，包括密码保护。
 98 | 
 99 | ### 3.1 数据库保存逻辑
100 | 
101 | 用户提交的内容以及相关的销毁条件会通过AJAX请求传递到后端的`create_paste.php`脚本。以下是核心的后端处理逻辑：
102 | 
103 | ```php
104 | $content = $_POST['content'];
105 | $password = $_POST['password'] ? password_hash($_POST['password'], PASSWORD_DEFAULT) : null;
106 | $expiration_minutes = ($_POST['expire_condition'] == 'time') ? $_POST['expiration_minutes'] : null;
107 | $max_views = ($_POST['expire_condition'] == 'views') ? $_POST['max_views'] : null;
108 | $identifier = bin2hex(random_bytes(8)); // 生成唯一标识符
109 | ```
110 | 
111 | 然后使用PDO连接数据库并将用户的内容保存到`pastes`表中。
112 | 
113 | ```php
114 | $db = connect();
115 | $stmt = $db->prepare("INSERT INTO pastes (content, password, expiration_minutes, max_views, identifier) VALUES (?, ?, ?, ?, ?)");
116 | $stmt->execute([$content, $password, $expiration_minutes, $max_views, $identifier]);
117 | ```
118 | 
119 | 返回成功后，平台会返回一个包含访问链接的JSON响应：
120 | 
121 | ```php
122 | $response = [
123 |     'success' => true,
124 |     'link' => $link,
125 |     'expiration_minutes' => $expiration_minutes,
126 |     'max_views' => $max_views,
127 |     'password_set' => $password ? $_POST['password'] : null
128 | ];
129 | echo json_encode($response);
130 | ```
131 | 
132 | ### 3.2 销毁逻辑
133 | 
134 | 内容的销毁是通过检查当前时间或访问次数来实现的。访问内容时，后端脚本会根据内容的创建时间或访问次数进行判断。如果条件已满足，自动删除对应的内容。
135 | 
136 | ```php
137 | if ($paste['expiration_minutes'] !== null) {
138 |     $createdTime->modify("+{$paste['expiration_minutes']} minutes");
139 |     if ($currentTime > $createdTime) {
140 |         // 内容过期，删除记录
141 |         $db->prepare("DELETE FROM pastes WHERE identifier = :identifier")->execute([':identifier' => $identifier]);
142 |         exit('该内容已过期。');
143 |     }
144 | }
145 | ```
146 | 
147 | 同样，访问次数的限制也是通过数据库字段`max_views`和`current_views`来实现的。
148 | 
149 | ## 4. 内容查看逻辑
150 | 
151 | 查看内容时，后端通过`view.php`页面接收访问请求。用户访问内容的URL带有唯一标识符`id`，通过它查询数据库中的对应记录。
152 | 
153 | ### 4.1 验证和访问控制
154 | 
155 | 如果内容设置了密码保护，系统会要求用户输入密码。后端使用`password_verify`验证用户输入的密码是否匹配。
156 | 
157 | ```php
158 | if ($paste['password']) {
159 |     if ($_SERVER['REQUEST_METHOD'] == 'POST') {
160 |         $entered_password = $_POST['password'];
161 |         if (!password_verify($entered_password, $paste['password'])) {
162 |             exit('密码不正确。');
163 |         }
164 |     } else {
165 |         // 显示密码输入表单
166 |     }
167 | }
168 | ```
169 | 
170 | ### 4.2 内容显示
171 | 
172 | 验证通过后，后端会增加该内容的访问次数并展示内容：
173 | 
174 | ```php
175 | $db->prepare("UPDATE pastes SET current_views = current_views + 1 WHERE identifier = :identifier")->execute([':identifier' => $identifier]);
176 | ```
177 | 
178 | 内容以HTML的形式呈现在用户界面上：
179 | 
180 | ```php
181 | <pre><?php echo htmlspecialchars($paste['content']); ?></pre>
182 | ```
183 | 
184 | ## 5. 总结
185 | 
186 | 本阅后即焚平台实现了一个简单而有效的系统，用户可以提交并设定销毁条件（时间或访问次数）来保护隐私。核心逻辑包括：
187 | 
188 | - **前端**：通过AJAX提交数据并处理返回结果。
189 | - **后端**：验证并存储用户数据，处理销毁逻辑。
190 | - **查看**：用户通过唯一链接查看内容，并根据条件自动销毁。
191 |   这种实现方案可以有效用于临时信息分享、敏感数据传递等场景，确保数据不会长期存储，提升安全性。

  1 | /**
  2 |  * When sorting a DataTable you might find that you want to keep a specific
  3 |  * item at the top or bottom of the table. For example when sorting a column
  4 |  * of numbers, if a value is `null` or `N/A` you might want to keep it at the
  5 |  * bottom of the table, regardless of if ascending or descending sorting is
  6 |  * applied. This plug-in provides that ability.
  7 |  *
  8 |  * You must call the `$.fn.dataTable.absoluteOrder` with information about the
  9 |  * value(s) you wish to make absolute in the sorting order and store the
 10 |  * returned value, assigning it to the `columns.type` option for the column
 11 |  * you wish this sorting to be applied to.
 12 |  *
 13 |  * For number based columns a `$.fn.dataTable.absoluteOrderNumber` function is
 14 |  * also available.
 15 |  *
 16 |  * @name Absolute sorting
 17 |  * @summary Keep one or more items at the top and/or bottom of a table when sorting
 18 |  * @author [Allan Jardine](//datatables.net)
 19 |  * @depends DataTables 1.10+
 20 |  *
 21 |  * @example
 22 |  *    var namesType = $.fn.dataTable.absoluteOrder( [
 23 |  *      { value: '', position: 'top' }
 24 |  *    ] );
 25 |  *    
 26 |  *    var numbersType = $.fn.dataTable.absoluteOrderNumber( [
 27 |  *      { value: 'N/A', position: 'bottom' }
 28 |  *    ] );
 29 |  *    
 30 |  *    $('#example').DataTable( {
 31 |  *      columnDefs: [
 32 |  *        { type: namesType, targets: 0 },
