# MSW Open Music Project ## Introduction A light weight personal music streaming platform. ![demo1](demo1.jpg) [toc] ## TODO - Restructure,为多人协作做好准备 ### 前端部分更改 - 修复页面 CSS 溢出问题 - 显示操作执行世界 页面数量至少 10 个(目前 5 个),预计添加如下页面 - 文件详情页,可以修改单个文件的信息 - 文件评论页,可对文件进行评论 - 最新动态页,查看最近播放的曲目、最近的评论 - 登录/注册页,取代现有的 token 逻辑 - FfmpegConfigs 配置页面 - 意见反馈的查看页面 ### 后端部分更改 - 返回操作执行时间 - 修复 Prepare 模式转码不完整但仍然被 tmpfs 记录为成功转码的问题 - FfmpegConfigs 由目前的字典格式改为列表格式 - 为 sqlite3 添加数据库单线程锁 - 添加外键约束 - Update 功能自动检查重复的项目并忽略,只添加新的项目 - Token 验证方法改为 暱称 + 密码 的方法,管理员使用 admin 保留关键字作为暱称。 需要 8 个 entities 和 6 个 relationship,目前有 3 个 entities,和 1 个 relationship 目前有 - files 文件表,数量 50,000 - folders 文件夹表,数量 3,000 - feedbacks 反馈留言表 计划添加 - users 用户表 - comments 管理表 - playbacks 播放记录表 - likes 点赞记录表 ## 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 Start back-end server. Server will listen on 8080 port. Build the font-end web page, then go to By default: - URL matched `/api/*` will process by back-end server. - Others URL matched `/*` will be served files under `web/build/` ### Run back-end server Configuration file is `config.json`, **Please modify your `token`** 。 Default `ffmpeg_threads` is 1. Seems value larger than 1 will not increase the audio encode speed. #### 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.** ### Run font-end web page Open your web browser to you will see the web pages. ## 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 using native method. 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. ## 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" } ``` ### Anonymous API Anonymous API can be called by anonymous. - `/api/v1/hello` Just for test purpose. - `/api/v1/get_file` Get a file with `stream` mode. - Request example ```json { "id": 123 } ``` - `/api/v1/get_file_direct` Get a file with standart `http` methods, implement by `http.ServeFile` method. - Request example `/api/v1/get_file_direct?id=30` - `/api/v1/search_files` Search files by filename. - Request example ```json { "filename": "miku", "limit": 10, "offset" 0 } ``` Search all files' name like `%miku%`. `%` is the wildcard in SQL. For example, `"filename": "miku%hatsune"` can match `hatsune miku`. `limit` Numbers of files in the respond. Should be within 1 - 10; `offset` It is the offset of the result, related to the page turning function. - Respond example ```json { "files": [ { "id": 30, "folder_id": 100, "folder_name": "wonderful", "filename": "memories.flac", "filesize": 1048576 }, { "id": 31, "folder_id": 100, "folder_name": "wonderful", "filename": "memories (instrunment).flac", "filesize": 1248531 } ] } ``` `id` Identification of file. `folder_id` Identification of folder. `foldername` Folder name where the file in. `filename` File name. `filesize` File size, unit is byte. - `/api/v1/search_folders` Search folders. - Request example. ```json { "foldername": "miku", "limit": 10, "offset": 0, } ``` Search all folders' name like `%miku%`. `%` is the wildcard in SQL. For example, `"filename": "miku%hatsune"` can match `hatsune miku`. `limit` Numbers of files in the respond. Should be within 1 - 10; `offset` It is the offset of the result, related to the page turning function. - Respond example ```json { "folders": [ { "id": 100, "foldername": "folder name" }, { "id": 101, "foldername": "folder name (another)" } ] } ``` `id` Identification of folder. `foldername` Folder name. - `/api/v1/get_files_in_folder` Get files in a specify folder. - Request example. ```json { "folder_id": 123, "limit": 10, "offset": 0 } ``` - Respond example. Same with `/api/v1/search_files` - `/api/v1/get_random_files` Randomly get 10 files. - Request example. GET `/api/v1/get_random_files` - Respond example. Same with `/api/v1/search_files` - `/api/v1/get_file_stream` Stream file with a ffmpeg config name. - Request example. GET `/api/v1/get_file_stream?id=123&config=OPUS%20128k` - `/api/v1/get_ffmpeg_config_list` Get ffmpeg config list - Request example GET `/api/v1/get_ffmpeg_config_list` - Respond example ```json { "ffmpeg_config_list": [ {"name": "OPUS 256k", "args": "-c:a libopus -ab 256k"}, {"name": "WAV", "args": "-c:a wav"} ] } ``` - `/api/v1/feedback` Send a feedback. - Request example ```json { "feedback": "some suggestions..." } ``` - Respond OK. - `/api/v1/get_file_info` Get information of a specify file. - Request example. ```json { "ID": 123 } ``` - Respond example. ```json { "id": 30, "folder_id": 100, "folder_name": "wonderful", "filename": "memories.flac", "filesize": 1048576 }, ``` - `/api/v1/get_file_stream_direct` Get a ffmpeg converted file with native http method. This API support continue getting a partially-downloaded audio. Note, you should call `/api/v1/prepare_file_stream_direct` first and wait for its respond, then call this API. - Request example GET `/api/v1/get_file_stream_direct?id=123&config=OPUS%20128k` - `/api/v1/prepare_file_stream_direct` Ask server to convert a file with specific ffmpeg config name. When the conver process is finished, server will reply with the converted file size. - Request example ```json { "id": 123, "config_name": "OPUS 128k" } ``` - Respond example ```json { "filesize": 1973241 } ``` ### API needs token - `/api/v1/walk` Walk directory, add all files and folders to database. - Request example ```json { "token": "your token", "root": "/path/to/root", "pattern": [".wav", ".flac"] } ``` `token` The token in `config.json` file. `root` Root directory server will walk throught `pattern` A list of pattern that files ends with. Only files matched a pattern in list will be add to database. - Respond OK - `/api/v1/reset` Rest the **files and folders table** - Request example ```json { "token": "your token" } ``` - Respond OK - `/api/v1/add_ffmpeg_config` Add ffmpeg config. Will be changed in future. - Request example ```json { "token": "your token", "name": "OPUS", "ffmpeg_config": { "args": "-c:a libopus -ab 256k" } } ``` `name` Name of the ffmpeg config. `ffmpeg_config` `args` - Respond OK ## Font-end API references Currently only few APIs in font-end. - `/#/files/39/share` Share a specific file. - `/#/folders/2614` Show files in a specific folder.
