# Client-Server Protocol

Protocol version: "0.1"

## 1. Start a connection

To start a connection you have to check the versions and verify the login.
Only if step 1.1 and 1.2 have been accomplished a usable connection is negotiated.

### 1.1 Version check
Client:
```
{
	"version": string
}
```


Server:
```
{
	"version": string,
	"accept": bool
}
```

If `accept` is `true` the connection is valid. Else the connection will be terminated after the server answered.

### 1.2 Login
Client:
```
{
	"user": string,
	"pass": string
}
```

Server:
```
{
	"accept": bool
}
```

If `accept` is `true` the connection is valid and the user is logged in. Else the connection will be terminated after the server answered.


## 2. Sending commands

Commands can be sent by the client after a connection has been negotiated (See 1).
Commands can be used unrelated to each other.

### 2.1 Status command
Client:
```
{
	"command": "status"
}
```

Server:
```
{
	"command": "status",
	"response": string
}
```

## 3. Close connection

### 3.1 Close command

Client:
```
{
	"command": "close"
}
```


Server:
```
{
	"command": "close",
	"response": "bye"
}
```
