|
|
|
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.
|
|

|
The front-end HTML files are under `web/build`
|
|
|

|
|
- `addr` string type. The listen address and port.
|
|
- `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.

|
- `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
|
|
|
|
API does not need to respond any data will return the following JSON object.
|
|
|
|
```json
|
|
{
|
|
"status": "OK"
|
|
}
|
|
```
|
|
|
|
Sometime errors happen, server will return the following JSON object, which `error` is the detailed error message.
|
|
|
|
```json
|
|
{
|
|
"error": "Wrong password"
|
|
}
|
|
```
|
|
|
|
API does not need to send any data should use `GET` method, otherwise use `POST` method.
|
|
|
|
Server use cookies to authenticate a user. Any request without cookies will be consider from an anonymous user (aka. user with ID `1`).
|
|
