-
-🔴 演示 Demo: <https://msw-open-music.live>
-
-> 找一首歌最好的方法是：打开一个超长的歌单，然后随机播放，直到你找到为止。
-
-一个 💪 轻量级 ⚡️ 高性能 🖥️ 跨平台的 个人音乐串流平台。管理你现有的音乐文件并在其他设备上播放。
-
-前端网页应用基于 `react.js` 和 `water.css` 构建。后端服务器程序使用 `golang` 和 `sqlite` 构建。
-
-## 介绍
-
-截图
-
-![demo1](demo1.jpg)
-
-### 功能特点
-
-- 🔎 索引现有的音乐文件，并记录文件名和文件夹元信息
-
-- 📕 使用 文件夹 📁 标签 🏷️ 评论 💬 来管理你的音乐。
-
-- 🌐 提供一个轻量高效的网页前端并支持多种语言。
-
-- 👥 支持多用户。
-
-- 🔥 调用 `ffmpeg` 配合可自定义的预设配置来转码你的音乐。
-
-- 🔗 分享音乐链接给好友！
-
-### 如果你遇到过这样的烦恼...你就是目标用户
-
-- 硬盘上存了一堆音乐，但没有一个很好的播放器. 🖴
-
-- 下载了体积非常大的无损音乐，在设备间移动很困难. 🎵
-
-- 想要在其他 电脑/手机 上听 电脑/服务器 上储存的音乐. 😋
-
-- 想给你的好友分享本地音乐. 😘
-
-## 使用方法
-
-1. 修改 `config.json` 配置文件中的 `secret` 值
-
-2. 运行后端服务器程序 `msw-open-music.exe` 或者 `msw-open-music`. 服务默认监听 8080 端口。 然后打开 <http://127.0.0.1:8080> 去创建的一个管理员帐号。
-
-前端 HTML 文件存放在 `web/build` 目录下。
-
-### 创建第一个管理员帐号
-
-第一个创建的管理员帐号会被自动激活，其他后续创建的管理员帐号需要管理员手动激活。
-
-请前往注册页面，选择角色为 管理员，然后注册第一个管理员帐号。
-
-#### config.json
-
-- `secret` 字符串类型。用来加密 session 会话。
-
-- `database_name` 字符串类型。`sqlite3` 数据库的文件名。如果不存在，会自动创建。
-- `addr` 字符串类型。监听地址和端口。
-- `ffmpeg_config_list` 列表类型。预设的 `ffmpeg` 配置文件。包含 `ffmpegConfig` 对象。
-- `file_life_time` 整数类型（秒）。临时文件的生命周期。如果临时文件超过这个时间没有被访问，那么将会被自动删除。
-- `cleaner_internal` 整数类型（秒）。`tmpfs` 检查临时文件的间隔时间。
-- `root` 字符串类型。存放临时文件的目录。默认是 `/tmp`。**Windows用户请修改成可用的目录**。如果不存在，将会被自动创建。
-- `permission` 各个 API 的权限等级。
-  - `0` 无需任何权限。
-  - `1` 需要管理员（最高级别）权限等级。
-  - `2` 需要普通用户权限等级，也就是说，管理员和普通用户都有权访问此等级的 API ，而 匿名用户 则没有权限访问。
-  - 如果你想避免 API 被滥用，可以调整下面 5 个与串流相关的 API 权限等级。
-    - `/get_file` 使用 `io.copy()` 方法串流
-    - `/get_file_direct` 使用 `http.serveFile()` 方法串流
-    - `/get_file_stream` 调用 `ffmpeg` 并串流其标准输出 `stdout`
-    - `/prepare_file_stream_direct` 调用 `ffmpeg` 预转码一个文件
-    - `/get_file_stream_direct` 使用 `http.serveFile()` 获取预转码结束的临时文件
-  - 其他在 `config.json` 中没有设定的 API 将默认拥有 `0` 的权限等级。
-
-对于 Windows 用户，请确保 `ffmpeg` 正确安装并设置环境变量。
-
-## 开发
-
-欢迎任何 issue / pull request / feature request
-
-### 主要变更历史
-
-- `v1.0.0` 第一个版本。核心串流功能可用。
-- `v1.1.0` 使用 `React` 重构前端。
-- `v1.2.0` 数据库 DBMS 课程作业。添加 用户、标签、评论 和其他功能。
-
-### ER Diagram
-
-Database Entities Relationship Diagram
-
-![ER Diagram](erdiagram.png)
-
-- `avatar` 目前没有在使用。
-
-- 第一次运行程序时，程序会自动创建一个 ID 为 `1` 的匿名用户。所有未登陆的用户都会自动登陆到这个账户。
-
-- `tmpfs` 储存在内存中，每次重新启动后端程序将会清空记录的信息。
-
-### 关于 tmpfs
-
-如果前端的播放器勾选了 `预转码` 选项，后端程序会先将文件转码到临时目录中，转码完成后再串流文件。这么做可以实现断点续传，解决由于网络波动导致 `ffmpeg` 管道链接断开而终止转码的问题。
-
-默认的临时文件夹目录是 `/tmp`，这是 Linux 系统中通用的临时目录。默认的生存时间是 600 秒（10 分钟）。如果超过这个时间没有访问该临时文件，那么后端程序将会自动删除它。
-
-### 后端 API 设计
-
-一个不需要返回任何有用数据的 API 将会返回下面的 JSON 对象
-
-```json
-{
-  "status": "OK"
-}
-```
-
-当错误发生时，后端会返回如下格式的 JSON 对象。`error` 是对错误信息的详细描述文本。
-
-```json
-{
-  "error": "Wrong password"
-}
-```
-
-不需要传递参数的 API 使用 `GET` 方法，否则使用 `POST` 方法。（忽略 RESTFUL 设计）
-
-后端使用 cookies 来实现用户会话管理。任何不带 cookies 的请求会被认为是由 匿名用户 发送的（也就是 ID 为 `1` 的用户）
-
-一些重要的源代码文件
-
-- `pkg/api/api.go` 定义各个 API 的 URL 和对应函数。
-
-- `pkg/database/sql_stmt.go` 定义 SQL 语句和做一些初始化工作。
-
-- `pkg/database/struct.go` 定义 JSON 和 数据库对象 的 数据结构。

+## 编译 & 构建
+
+## How to build
+
+### Build the back-end server
+
+`make linux` or `make windows`
+
+The executable file is named `msw-open-music` or `msw-open-music.exe`
+
+### Build the font-end web pages
+
+To build production web page `make web`
+
+This command will go into `web` directory and install `node_modules`. Then execute `npm run build` command. The built web pages is under `web/build` directory.
+
+To start the development, run `cd web` and `npm start`
 
 ## Usage
 
-1. Modify the `secret` in `config.json`
+Start back-end server. Server will listen on 8080 port.
 
-2. Run back-end server `msw-open-music.exe` or `msw-open-music`. Server will listen on 8080 port by default. Then open <http://127.0.0.1:8080> to setup first admin account.
+Build the font-end web page, then go to <http://127.0.0.1:8080>
 
-The front-end HTML files are under `web/build`
+By default:
 
-### Setup first admin account
+- URL matched `/api/*` will process by back-end server.
+- Others URL matched `/*` will be served files under `web/build/`
 
-The first administrator account will be active automatically, other administrator accounts need active manually.
+### Run back-end server
 
-Go to register page, select the role to admin, and register the first admin account.
+Configuration file is  `config.json`， **Please modify your `token`** 。
 
-#### config.json
+Default `ffmpeg_threads` is 1. Seems value larger than 1 will not increase the audio encode speed.
 
-- `secret` string type. Secret to encrypt the session.
+#### config.json description
 
 - `database_name` string type. The filename of `sqlite3` database. Will create if that file doesn't exist.
 - `addr` string type. The listen address and port.
+- `token` string type. Password.
 - `ffmpeg_config_list` list type, include `ffmpegConfig` object.
 - `file_life_time` integer type (second). Life time for temporary file. If the temporary file is not accessed for more than this time, back-end server will delete this file.
 - `cleaner_internal` integer type (second). Interval for `tmpfs` checking temporary file.
-- `root` string type. Directory to store temporary files. Default is `/tmp`, **please modify this directory if you are using Windows.** Directory will be created if not exists.
+- `root` string type. Directory to store temporary files. Default is `/tmp`, **please modify this directory if you are using Windows.**
-- `permission`. Specify each API's permission level.
-  - `0` for no permission required.
-  - `1` require admin level (highest level) permission.
-  - `2` require normal user level permission. That is, both admins and registered users can access to this URL, except anonymous users.
-  - If you want to avoid abuse of the playback API, you can adjust the permission level for these 5 playback-related APIs.
-    - `/get_file` get file with `io.copy()` method
-    - `/get_file_direct` get file with `http.serveFile()` method
-    - `/get_file_stream` call ffmpeg and stream its `stdout` output
-    - `/prepare_file_stream_direct` call ffmpeg to convert a file
-    - `/get_file_stream_direct` get the converted file with `http.serveFile()`
-  - Other URLs not metion in `config.json` will have `0` permission level by default.
 
-For windows user, make sure you have `ffmpeg` installed.
+### Run font-end web page
 
-## Development
+Open your web browser to <http://127.0.0.1:8080> you will see the web pages.
 
-Any issues or pull requests are welcome.
+## About tmpfs
 
-### Major changes log
+If the `Prepare` mode is enabled in the font-wed player, back-end server will convert the whole file into the temporary folder, then serve file using native method. This can avoid ffmpeg pipe break problem cause by unstable network connection while streaming audio.
-
-- `v1.0.0` First version. Implement the core streaming function.
-- `v1.1.0` Use `React` to rewrite the font-end web pages.
-- `v1.2.0` Add user, tag, review and other functions for DBMS course project.

-
-- `avatar` is not using currently
-
-- The first time you run the program, the server will create an anonymous user with id `1`. All users who are not logged in will be automatically logged in to this account.
-
-- `tmpfs` is store in memory, which will be empty everytime server restart.

-### About tmpfs
-
-If the `Prepare` mode is enabled in the font-wed player, back-end server will convert the whole file into the temporary folder, then serve file. This can avoid `ffmpeg` pipe break problem cause by unstable network connection while streaming audio.
 
 The default temporary folder is `/tmp`, which is a `tmpfs` file system in Linux operating system. Default life time for temporary files is 600 seconds (10 minutes). If the temporary file is not accessed for more than this time, back-end server will delete this file.
 
-### Back-end API design
+## Change log
+
+- `v1.0.0` First version. Ready to use in production environment.
+- `v1.1.0` Use `React` to rewrite the font-end web pages (Previous using `Vue`).
+
+## Back-end API references
+
+API named `stream` means it transfer data using `io.Copy`, which **DO NOT** support continue getting a partially-downloaded audio.
 
 API does not need to respond any data will return the following JSON object.
 
 ```json
 {
-  "status": "OK"
+    "status": "OK"
 }
 ```
 
-Sometime errors happen, server will return the following JSON object, which `error` is the detailed error message.
+### Anonymous API
 
-```json
+Anonymous API can be called by anonymous.
-{
-  "error": "Wrong password"
-}
-```
 
-API does not need to send any data should use `GET` method, otherwise use `POST` method.
+- `/api/v1/hello` Just for test purpose.
 
-Server use cookies to authenticate a user. Any request without cookies will be consider from an anonymous user (aka. user with ID `1`).
+- `/api/v1/get_file` Get a file with `stream` mode.
 
-Some important source code files:
+  - Request example
 
-- `pkg/api/api.go` define URL
+    ```json
+    {
+        "id": 123
+    }
+    ```
 
-- `pkg/database/sql_stmt.go` define SQL queries and do the init job.

+# DBMS Group Project Problem Description
+
+- Group 1
+
+The Internet infrastructure construction has made the network speed development faster. With the fast Internet, people are gradually migrating various data and services to the cloud. For example, NetEase Cloud Music, Spotify, and Apple Music, we call them streaming media platforms. The definition of streaming media platform is that users purchase the digital copyright of music and then play the music online on the platform.
+
+Generally speaking, users cannot buy music that is not available on the platform. The user cannot download the digital file of the music (the user purchases the right to play instead of the right to copy). Users cannot upload their music to the platform.
+
+However, in the era of digital copyright, there are still many advantages to getting original music files, such as no need to install a dedicated player; free copying to other devices (without violating copyright); no risk of music unavailable from the platform; no play records and privacy will be tracked by the platform.
+
+Some people don't like streaming platforms. They like to collect music (download or buy CDs) and save it on their computers. But as more and more music is collected (over 70,000 songs and in total size of 800GB), it becomes very difficult to manage files. It is difficult for them to find where the songs they want to listen to are saved. Also, lossless music files are large and difficult to play online.
+
+As long as there no such "Self-hosted music streaming platform" software available, we decided to develop a project based on database knowledge to help people who have collected a lot of music to enjoy their music simply.
+
+We will handle various relevant types of data in our database. Including song name, album name, file size, update date, rating, comment, user information, etc. They are highly relevant, so using a relational database will be a good choice.
+
+The features of the project we designed are as follows:
+
+- Open. Independent front-end (GUI) and back-end (server program), using API to communicate.
+- Easy to use. Minimize dependencies, allowing users to configure quickly and simply.
+- Lightweight. The program is small in size and quick to install.
+- High performance. Only do what should be done, no features that will lead to poor performance.
+- Cross-platform. The project can run on computers, mobile phones, Linux, Windows, macOS, and X86 and ARM processor architectures.
+- Extensibility. Access to cloud OSS (Object Storage Service), reverse proxy, or other external software.
+
+Our project has the following functions:
+
+- Index file. Index local files into the database.
+- Search. Search for music based on name/album/tag/comment, sorted by rating or other columns.
+- Play. Play music online, play music randomly and play music at a low bit rate on a bad network.
+- User management. Users can register and log in.
+- Comment. Users can give a like or comment on the music.
+- Management. The administrator can upload music, update or delete the database.
+- Share. Generate a link to share the music with others.
+
+After research and discussion, in order to meet the above requirements, we decided to use the Golang programming language on the backend. SQLite as a database program. Vue as the front-end GUI interface.

-
-### `npm run eject`
-
-**Note: this is a one-way operation. Once you `eject`, you can’t go back!**
-
-If you aren’t satisfied with the build tool and configuration choices, you can `eject` at any time. This command will remove the single build dependency from your project.
-
-Instead, it will copy all the configuration files and the transitive dependencies (webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except `eject` will still work, but they will point to the copied scripts so you can tweak them. At this point you’re on your own.
-
-You don’t have to ever use `eject`. The curated feature set is suitable for small and middle deployments, and you shouldn’t feel obligated to use this feature. However we understand that this tool wouldn’t be useful if you couldn’t customize it when you are ready for it.
