加载插件后使用 require 声明插件依赖，直接使用 localstore 插件提供的函数即可。

from pathlib import Path
from nonebot import require

require("nonebot_plugin_localstore")

import nonebot_plugin_localstore as store

plugin_cache_dir: Path = store.get_plugin_cache_dir()
plugin_cache_file: Path = store.get_plugin_cache_file("filename")
plugin_config_dir: Path = store.get_plugin_config_dir()
plugin_config_file: Path = store.get_plugin_config_file("filename")
plugin_data_dir: Path = store.get_plugin_data_dir()
plugin_data_file: Path = store.get_plugin_data_file("filename")

在项目安装插件后，可以使用 nb-cli 查看具体的存储路径：

nb localstore

参考路径如下：

• macOS: ~/Library/Caches/<AppName>
• Unix: ~/.cache/<AppName> (XDG default)
• Windows: C:\Users\<username>\AppData\Local\<AppName>\Cache

• macOS: ~/Library/Application Support/<AppName>
• Unix: ~/.local/share/<AppName> or in $XDG_DATA_HOME, if defined
• Win XP (not roaming): C:\Documents and Settings\<username>\Application Data\<AppName>
• Win 7 (not roaming): C:\Users\<username>\AppData\Local\<AppName>

• macOS: same as user_data_dir
• Unix: ~/.config/<AppName>
• Win XP (roaming): C:\Documents and Settings\<username>\Local Settings\Application Data\<AppName>
• Win 7 (roaming): C:\Users\<username>\AppData\Roaming\<AppName>
