# gc-opencommand-plugin

[中文](README.md) | English

A plugin that opens the GC command execution interface for third-party clients

## Server installation
1. Download the `jar` in [Release](https://github.com/jie65535/gc-opencommand-plugin/releases)
2. Put it in the `plugins` folder

## Console connection
1. When starting for the first time, a `opencommand-plugin` directory will be generated under the `plugins` directory, open and edit `config.json`
2. Set the value of `consoleToken` to your connection key. It is recommended to use a long random string of at least 32 characters.
3. Restart the server to take effect
4. Select the console identity in the client, and fill in your `consoleToken` to run the command as the console identity

## Build
1. `git clone https://github.com/jie65535/gc-opencommand-plugin`
2. `cd gc-opencommand-plugin`
3. `mkdir lib`
4. `mv path/to/grasscutter-1.x.x-dev.jar ./lib`
5. `gradle build`

## Player
1. Fill in the service address in the client to confirm whether it supports
2. Fill in the UID and send the verification code
3. Fill in the **4-digit integer verification code** received in the game into the client verification
4. Enjoy the convenience!

## Client request
1. `ping` to confirm whether the `opencommand` plugin is supported
2. `sendCode` sends a verification code to the specified player (re-send is not allowed within 1 minute), and save the returned `token`
3. Send `verify` check using `token` and **4-digit integer verification code**
4. If the verification is passed, you can use the `token` to execute the `command` action
