+### 关于聊天记录储存的方案概述
+
+自 3月10日 开始，这个项目遇到了一些瓶颈，停止开发
+
+我在这段时间的精力也被耗尽
+
+故此，在今天(3月26日)重新思考，理清思路
+
+预计3月28日左右实现此功能
+
+#### 基本想法
+
+##### 写入
+
+对于储存来说，从 0 开始计次，一条消息对应一个 ID
+
+第一条消息的 ID 为 1， 计次文件储存为 1
+
+为了性能，每个消息使用一个 JSON 文件储存
+
+##### 读取
+
+当读取时，从计次文件获取计次数，并从此数字递减，以此读取
+
+然后储存到数组并直接返回给用户
+
+客户端消息的 ID 必须要同步，这是为了范围读取以前的消息
+
+#### 和以前的区别
+
+在我的聊天软件第一版、第二版中，均由 PHP 作为后端
+
+写入则直接追加，读取整个返回
+
+这种做法的最大缺陷是浪费性能
+
+我曾想过使用 SQL，不过潜在的风险以及我的技术都能符合我的要求
+
+故此，便有了这个方法

+### 最终目标
+
+铃之椅服务端的 Node 实现，目前最低目标如下
+
+* 全 API 可用
+* 可配置
+* 开箱即用
+
+如果有时间，可以完成下面的目标
+
+* 尽可能使用异步
+* 最大利用 I/O 性能
+
+#### API 实现
+
+一般约定: ☘️=已完成
+
+* 用户
+    * 登录 ☘️
+    * 注册 ☘️
+    * 修改密码
+    * 令牌机制 ☘️
+    * 用户资料
+        * 头像 ☘️
+        * 昵称 ☘️
+    * 安全
+        * 账号冻结
+        * 权限管理
+        * 匿名
+
+* 聊天
+    * 双方私聊 ☘️ 完善中
+    * 多人群聊
+    * 临时对话
+    * 多媒体
+    * 文件
+    * 群聊资料
+        * 介绍
+        * 头像
+        * 群名称
+    * 安全
+        * 权限管理
+            * 管理员
+            * 入群权限
+            * 可否被查找
+            * 功能限制
+            * 管理匿名
+
+注:
+    1. 为了保障管理员层安全，匿名的账号或管理员的信息仍然能被伺服器管理员所查询，不过请放心，一般来说不会有任何正常人能查询到你
+    2. 多媒体应该能够定时删除而非永久保存，否则伺服器会炸掉的
+    3. 每个功能都应该验证令牌

+服务端:
+
+  1. 克隆本仓库源代码到本地
+
+  2. ~~(仅需要集成时) 复制 client_src 中全部文件到 ling_chair_http~~ 默认就是集成的
+
+  3. 执行 run.sh
+  
+  4. Enjoy it :)
+
+网页端:
+
+三种方法任选一个
+
+  * 直接使用和服务端集成的网页 (推荐)
+
+  * 克隆本仓库到本地并运行本地 HTTP 服务端
