## 响应器使用
|
|
|
|
|
|
2024-04-18 18:28:31 +08:00
|
|
|
|
本插件基于 **Alconna**,为 **Nonebot** 提供了一类新的事件响应器辅助函数 `on_alconna`:
|
2024-02-09 14:48:48 +08:00
|
|
|
|
|
|
|
|
|
```python
|
|
|
|
|
def on_alconna(
|
|
|
|
|
command: Alconna | str,
|
|
|
|
|
skip_for_unmatch: bool = True,
|
|
|
|
|
auto_send_output: bool = False,
|
|
|
|
|
aliases: set[str | tuple[str, ...]] | None = None,
|
|
|
|
|
comp_config: CompConfig | None = None,
|
|
|
|
|
extensions: list[type[Extension] | Extension] | None = None,
|
|
|
|
|
exclude_ext: list[type[Extension] | str] | None = None,
|
|
|
|
|
use_origin: bool = False,
|
|
|
|
|
use_cmd_start: bool = False,
|
|
|
|
|
use_cmd_sep: bool = False,
|
|
|
|
|
**kwargs,
|
|
|
|
|
...,
|
|
|
|
|
):
|
|
|
|
|
```
|
2023-08-04 17:32:43 +08:00
|
|
|
|
|
2024-04-18 18:28:31 +08:00
|
|
|
|
- `command`: Alconna 命令或字符串,字符串将通过 `AlconnaFormat` 转换为 Alconna 命令
|
2024-02-09 14:48:48 +08:00
|
|
|
|
- `skip_for_unmatch`: 是否在命令不匹配时跳过该响应
|
|
|
|
|
- `auto_send_output`: 是否自动发送输出信息并跳过响应
|
2024-04-18 18:28:31 +08:00
|
|
|
|
- `aliases`: 命令别名, 作用类似于 `on_command` 中的 aliases
|
2024-02-09 14:48:48 +08:00
|
|
|
|
- `comp_config`: 补全会话配置, 不传入则不启用补全会话
|
|
|
|
|
- `extensions`: 需要加载的匹配扩展, 可以是扩展类或扩展实例
|
|
|
|
|
- `exclude_ext`: 需要排除的匹配扩展, 可以是扩展类或扩展的id
|
|
|
|
|
- `use_origin`: 是否使用未经 to_me 等处理过的消息
|
|
|
|
|
- `use_cmd_start`: 是否使用 COMMAND_START 作为命令前缀
|
|
|
|
|
- `use_cmd_sep`: 是否使用 COMMAND_SEP 作为命令分隔符
|
2023-08-04 17:32:43 +08:00
|
|
|
|
|
2024-04-18 18:28:31 +08:00
|
|
|
|
`on_alconna` 返回的是 `Matcher` 的子类 `AlconnaMatcher` ,其拓展了如下方法:
|
2023-08-04 17:32:43 +08:00
|
|
|
|
|
2024-04-18 18:28:31 +08:00
|
|
|
|
- `.assign(path, value, or_not)`: 用于对包含多个选项/子命令的命令的分派处理(具体请看[条件控制](./matcher.mdx#条件控制))
|
|
|
|
|
- `.got_path(path, prompt, middleware)`: 在 `got` 方法的基础上,会以 path 对应的参数为准,读取传入 message 的最后一个消息段并验证转换
|
|
|
|
|
- `.set_path_arg(key, value)`, `.get_path_arg(key)`: 类似 `set_arg` 和 `got_arg`,为 `got_path` 的特化版本
|
|
|
|
|
- `.reject_path(path[, prompt, fallback])`: 类似于 `reject_arg`,对应 `got_path`
|
|
|
|
|
- `.dispatch`: 同样的分派处理,但是是类似 `CommandGroup` 一样返回新的 `AlconnaMatcher`
|
|
|
|
|
- `.got`, `send`, `reject`, ... : 拓展了 prompt 类型,即支持使用 `UniMessage` 作为 prompt

## 依赖注入
|
|
|
|
|
|
2024-02-09 14:48:48 +08:00
|
|
|
|
本插件提供了一系列依赖注入函数,便于在响应函数中获取解析结果:
|
|
|
|
|
|
2024-04-18 18:28:31 +08:00
|
|
|
|
- `AlconnaResult`: `CommandResult` 类型的依赖注入函数
|
|
|
|
|
- `AlconnaMatches`: `Arparma` 类型的依赖注入函数
|
|
|
|
|
- `AlconnaDuplication`: `Duplication` 类型的依赖注入函数
|
|
|
|
|
- `AlconnaMatch`: `Match` 类型的依赖注入函数
|
|
|
|
|
- `AlconnaQuery`: `Query` 类型的依赖注入函数
|
2023-08-04 17:32:43 +08:00
|
|
|
|
|
2024-04-18 18:28:31 +08:00
|
|
|
|
同时,基于 [`Annotated` 支持](https://github.com/nonebot/nonebot2/pull/1832),添加了两类注解:
|
2024-02-09 14:48:48 +08:00
|
|
|
|
|
2024-04-18 18:28:31 +08:00
|
|
|
|
- `AlcMatches`:同 `AlconnaMatches`
|
|
|
|
|
- `AlcResult`:同 `AlconnaResult`
|
2024-02-09 14:48:48 +08:00
|
|
|
|
|
|
|
|
|
可以看到,本插件提供了几类额外的模型:
|
|
|
|
|
|
2024-04-18 18:28:31 +08:00
|
|
|
|
- `CommandResult`: 解析结果,包括了源命令 `source: Alconna` ,解析结果 `result: Arparma`,以及可能的输出信息 `output: str | None` 字段
|
|
|
|
|
- `Match`: 匹配项,表示参数是否存在于 `all_matched_args` 内,可用 `Match.available` 判断是否匹配,`Match.result` 获取匹配的值
|
|
|
|
|
- `Query`: 查询项,表示参数是否可由 `Arparma.query` 查询并获得结果,可用 `Query.available` 判断是否查询成功,`Query.result` 获取查询结果
|
2024-02-09 14:48:48 +08:00
|
|
|
|
|
2024-04-18 18:28:31 +08:00
|
|
|
|
**Alconna** 默认依赖注入的目标参数皆不需要使用依赖注入函数, 该效果对于 `AlconnaMatcher.got_path` 下的 Arg 同样有效:
|
2023-08-26 21:49:28 +08:00
|
|
|
|
|
|
|
|
|
```python
|
2023-11-07 14:39:05 +08:00
|
|
|
|
async def handle(
|
2023-08-26 21:49:28 +08:00
|
|
|
|
result: CommandResult,
|
|
|
|
|
arp: Arparma,
|
2024-02-09 14:48:48 +08:00
|
|
|
|
dup: Duplication,
|
2023-08-26 21:49:28 +08:00
|
|
|
|
source: Alconna,
|
|
|
|
|
abc: str, # 类似 Match, 但是若匹配结果不存在对应字段则跳过该 handler
|
|
|
|
|
foo: Match[str],
|
|
|
|
|
bar: Query[int] = Query("ttt.bar", 0) # Query 仍然需要一个默认值来传递 path 参数
|
|
|
|
|
):
|
|
|
|
|
...
|
|
|
|
|
```

|
|
|
|
|
2024-02-09 14:48:48 +08:00
|
|
|
|
本插件提供了通用消息段标注, 通用消息段序列, 使插件使用者可以忽略平台之间字段的差异
|
2023-08-04 17:32:43 +08:00
|
|
|
|
|
2024-02-09 14:48:48 +08:00
|
|
|
|
响应器使用示例中使用了消息段标注,其中 `At` 属于通用标注,而 `Image` 属于 `onebot12` 适配器下的标注。

## 条件控制
|
|
|
|
|
|
2023-10-07 12:06:07 +08:00
|
|
|
|
本插件可以通过 `assign` 来控制一个具体的响应函数是否在不满足条件时跳过响应。

@pip_cmd.assign("install.pak", "pip")
|
|
|
|
|
async def update(res: CommandResult):
|
2023-08-26 21:49:28 +08:00
|
|
|
|
...
|
|
|
|
|
|
|
|
|
|
# 仅在命令为 `pip list` 时响应
|
2023-10-07 12:06:07 +08:00
|
|
|
|
@pip_cmd.assign("list")
|
|
|
|
|
async def list_(res: CommandResult):
|
2023-08-26 21:49:28 +08:00
|
|
|
|
...
|
|
|
|
|
|
2023-11-07 14:39:05 +08:00
|
|
|
|
# 在命令为 `pip install xxx` 时响应
|
2023-10-07 12:06:07 +08:00
|
|
|
|
@pip_cmd.assign("install")
|
|
|
|
|
async def install(res: CommandResult):
|
2023-08-26 21:49:28 +08:00
|
|
|
|
...
|
|
|
|
|
```
|
|
|
|
|
|
2023-10-07 12:06:07 +08:00
|
|
|
|
此外,使用 `AlconnaMatcher.dispatch` 还能像 `CommandGroup` 一样为每个分发设置独立的 matcher:
|
2023-08-26 21:49:28 +08:00
|
|
|
|
|
|
|
|
|
```python
|
2023-10-07 12:06:07 +08:00
|
|
|
|
update_cmd = pip_cmd.dispatch("install.pak", "pip")
|
2023-08-26 21:49:28 +08:00
|
|
|
|
|
2023-10-07 12:06:07 +08:00
|
|
|
|
@update_cmd.handle()
|
2023-11-07 14:39:05 +08:00
|
|
|
|
async def update(arp: CommandResult):
|
2023-08-26 21:49:28 +08:00
|
|
|
|
...
|
2023-10-07 12:06:07 +08:00
|
|
|
|
```
|
2023-08-26 21:49:28 +08:00
|
|
|
|
|
2023-10-07 12:06:07 +08:00
|
|
|
|
另外,`AlconnaMatcher` 有类似于 `got` 的 `got_path`:
|
|
|
|
|
|
|
|
|
|
```python
|
2023-11-07 14:39:05 +08:00
|
|
|
|
from nonebot_plugin_alconna import At, Match, UniMessage, on_alconna
|
2023-10-07 12:06:07 +08:00
|
|
|
|
|
2024-02-09 14:48:48 +08:00
|
|
|
|
|
2023-10-07 12:06:07 +08:00
|
|
|
|
test_cmd = on_alconna(Alconna("test", Args["target?", Union[str, At]]))
|
|
|
|
|
|
|
|
|
|
@test_cmd.handle()
|
2023-11-07 14:39:05 +08:00
|
|
|
|
async def tt_h(target: Match[Union[str, At]]):
|
2023-10-07 12:06:07 +08:00
|
|
|
|
if target.available:
|
2023-11-07 14:39:05 +08:00
|
|
|
|
test_cmd.set_path_arg("target", target.result)
|
2023-10-07 12:06:07 +08:00
|
|
|
|
|
|
|
|
|
@test_cmd.got_path("target", prompt="请输入目标")
|
|
|
|
|
async def tt(target: Union[str, At]):
|
|
|
|
|
await test_cmd.send(UniMessage(["ok\n", target]))
|
2023-08-04 17:32:43 +08:00
|
|
|
|
```
|
2023-09-09 11:53:06 +08:00
|
|
|
|
|
2023-11-07 14:39:05 +08:00
|
|
|
|
`got_path` 与 `assign`,`Match`,`Query` 等地方一样,都需要指明 `path` 参数 (即对应 Arg 验证的路径)
|
2023-10-07 12:06:07 +08:00
|
|
|
|
|
|
|
|
|
`got_path` 会获取消息的最后一个消息段并转为 path 对应的类型,例如示例中 `target` 对应的 Arg 里要求 str 或 At,则 got 后用户输入的消息只有为 text 或 at 才能进入处理函数。

## 响应器创建装饰
|
|
|
|
|
|
2024-04-18 18:28:31 +08:00
|
|
|
|
本插件提供了一个 `funcommand` 装饰器, 其用于将一个接受任意参数, 返回 `str` 或 `Message` 或 `MessageSegment` 的函数转换为命令响应器:
|
2024-02-09 14:48:48 +08:00
|
|
|
|
|
|
|
|
|
```python
|
|
|
|
|
from nonebot_plugin_alconna import funcommand
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
@funcommand()
|
|
|
|
|
async def echo(msg: str):
|
|
|
|
|
return msg
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
其等同于:
|
|
|
|
|
|
|
|
|
|
```python
|
|
|
|
|
from arclet.alconna import Alconna, Args
|
|
|
|
|
from nonebot_plugin_alconna import on_alconna, AlconnaMatch, Match
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
echo = on_alconna(Alconna("echo", Args["msg", str]))
|
|
|
|
|
|
|
|
|
|
@echo.handle()
|
|
|
|
|
async def echo_exit(msg: Match[str] = AlconnaMatch("msg")):
|
|
|
|
|
await echo.finish(msg.result)
|
|
|
|
|
|
|
|
|
|
```
|
|

## 类Koishi构造器
|
|
|
|
|
|
2024-04-18 18:28:31 +08:00
|
|
|
|
本插件提供了一个 `Command` 构造器,其基于 `arclet.alconna.tools` 中的 `AlconnaString`, 以类似 `Koishi` 中注册命令的方式来构建一个 **AlconnaMatcher** :
|
2024-02-09 14:48:48 +08:00
|
|
|
|
|
|
|
|
|
```python
|
|
|
|
|
from nonebot_plugin_alconna import Command, Arparma
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
book = (
|
|
|
|
|
Command("book", "测试")
|
|
|
|
|
.option("writer", "-w <id:int>")
|
|
|
|
|
.option("writer", "--anonymous", {"id": 0})
|
|
|
|
|
.usage("book [-w <id:int> | --anonymous]")
|
|
|
|
|
.shortcut("测试", {"args": ["--anonymous"]})
|
|
|
|
|
.build()
|
|
|
|
|
)
|
|
|
|
|
|
|
|
|
|
@book.handle()
|
|
|
|
|
async def _(arp: Arparma):
|
|
|
|
|
await book.send(str(arp.options))
|
|
|
|
|
```
|
|
|
|
|
|
2024-04-18 18:28:31 +08:00
|
|
|
|
甚至,你可以设置 `action` 来设定响应行为:
|
2024-02-09 14:48:48 +08:00
|
|
|
|
|
|
|
|
|
```python
|
|
|
|
|
book = (
|
|
|
|
|
Command("book", "测试")
|
|
|
|
|
.option("writer", "-w <id:int>")
|
|
|
|
|
.option("writer", "--anonymous", {"id": 0})
|
|
|
|
|
.usage("book [-w <id:int> | --anonymous]")
|
|
|
|
|
.shortcut("测试", {"args": ["--anonymous"]})
|
|
|
|
|
.action(lambda options: str(options)) # 会自动通过 bot.send 发送
|
|
|
|
|
.build()
|
|
|
|
|
)
|
|
|
|
|
```
|
|
|
|
|
|
2024-04-18 18:28:31 +08:00
|
|
|
|
## 返回值中间件
|
2024-02-09 14:48:48 +08:00
|
|
|
|
|
2024-04-18 18:28:31 +08:00
|
|
|
|
在 `AlconnaMatch`,`AlconnaQuery` 或 `got_path` 中,你可以使用 `middleware` 参数来传入一个对返回值进行处理的函数:
|
2024-02-09 14:48:48 +08:00
|
|
|
|
|
|
|
|
|
```python
|
|
|
|
|
from nonebot_plugin_alconna import image_fetch
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
mask_cmd = on_alconna(
|
|
|
|
|
Alconna("search", Args["img?", Image]),
|
|
|
|
|
)
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
@mask_cmd.handle()
|
|
|
|
|
async def mask_h(matcher: AlconnaMatcher, img: Match[bytes] = AlconnaMatch("img", image_fetch)):
|
|
|
|
|
result = await search_img(img.result)
|
|
|
|
|
await matcher.send(result.content)
|
|
|
|
|
```
|
|
|
|
|
|
2024-04-18 18:28:31 +08:00
|
|
|
|
其中,`image_fetch` 是一个中间件,其接受一个 `Image` 对象,并提取图片的二进制数据返回。
|

## 匹配拓展
|
|
|
|
|
|
2024-04-18 18:28:31 +08:00
|
|
|
|
本插件提供了一个 `Extension` 类,其用于自定义 AlconnaMatcher 的部分行为
|
2023-10-07 12:06:07 +08:00
|
|
|
|
|
2024-04-18 18:28:31 +08:00
|
|
|
|
例如一个 `LLMExtension` 可以如下实现 (仅举例):
|
2023-10-07 12:06:07 +08:00
|
|
|
|
|
|
|
|
|
```python
|
2023-11-07 14:39:05 +08:00
|
|
|
|
from nonebot_plugin_alconna import Extension, Alconna, on_alconna, Interface

def __init__(self, llm):
|
|
|

self.llm = llm
|
|
|
|
|
|

def post_init(self, alc: Alconna) -> None:
|

self.llm.add_context(alc.command, alc.meta.description)
|
|
|
|
|
|
|
|
|
|
async def receive_wrapper(self, bot, event, receive):
|
|
|
|
|
resp = await self.llm.input(str(receive))
|
|
|
|
|
return receive.__class__(resp.content)

那么添加了 `LLMExtension` 的响应器便能接受任何能通过 llm 翻译为具体命令的自然语言消息,同时可以在响应器中为所有 `llm` 参数注入模型变量。

例如内置的 `DiscordSlashExtension`,其可自动将 Alconna 对象翻译成 slash 指令并注册,且将收到的指令交互事件转为指令供命令解析:
|
2023-10-07 12:06:07 +08:00
|
|
|
|
|
|
|
|
|
```python
|
|
|
|
|
from nonebot_plugin_alconna import Match, on_alconna
|
2024-05-01 11:34:33 +08:00
|
|
|
|
from nonebot_plugin_alconna.builtins.plugins.discord import DiscordSlashExtension
|
2023-10-07 12:06:07 +08:00
|
|
|
|
|
2024-02-09 14:48:48 +08:00
|
|
|
|
|
2023-10-07 12:06:07 +08:00
|
|
|
|
alc = Alconna(
|
|
|
|
|
["/"],
|
|
|
|
|
"permission",
|
|
|
|
|
Subcommand("add", Args["plugin", str]["priority?", int]),
|
|
|
|
|
Option("remove", Args["plugin", str]["time?", int]),
|
|
|
|
|
meta=CommandMeta(description="权限管理"),
|
|
|
|
|
)
|
|
|
|
|
|
|
|
|
|
matcher = on_alconna(alc, extensions=[DiscordSlashExtension()])
|
|
|
|
|
|
|
|
|
|
@matcher.assign("add")
|
|
|
|
|
async def add(plugin: Match[str], priority: Match[int]):
|
|
|
|
|
await matcher.finish(f"added {plugin.result} with {priority.result if priority.available else 0}")
|
|
|
|
|
|
|
|
|
|
@matcher.assign("remove")
|
|
|
|
|
async def remove(plugin: Match[str], time: Match[int]):
|
|
|
|
|
await matcher.finish(f"removed {plugin.result} with {time.result if time.available else -1}")
|
2023-09-09 11:53:06 +08:00

|
2024-05-01 11:34:33 +08:00
|
|
|
|
目前插件提供了 4 个内置的 `Extension`,它们在 `nonebot_plugin_alconna.builtins.extensions` 下:
|
|
|
|
|
- `ReplyRecordExtension`: 将消息事件中的回复暂存在 extension 中,使得解析用的消息不带回复信息,同时可以在后续的处理中获取回复信息。
|
|
|
|
|
- `DiscordSlashExtension`: 将 Alconna 的命令自动转换为 Discord 的 Slash Command,并将 Slash Command 的交互事件转换为消息交给 Alconna 处理。
|
|
|
|
|
- `MarkdownOutputExtension`: 将 Alconna 的自动输出转换为 Markdown 格式
|
|
|
|
|
- `TelegramSlashExtension`: 将 Alconna 的命令注册在 Telegram 上以获得提示。

全局的 Extension 可延迟加载 (即若有全局拓展加载于部分 AlconnaMatcher 之后,这部分响应器会被追加拓展)

## 补全会话
|
|
|
|
|
|
|
|
|
|
补全会话基于 [`半自动补全`](./command.md#半自动补全),用于指令参数缺失或参数错误时给予交互式提示,类似于 `got-reject`:
|
|
|
|
|
|
|
|
|
|
```python
|
|
|
|
|
from nonebot_plugin_alconna import Alconna, Args, Field, At, on_alconna
|
|
|
|
|
|
|
|
|
|
alc = Alconna(
|
|
|
|
|
"添加教师",
|
|
|
|
|
Args["name", str, Field(completion=lambda: "请输入姓名")],
|
|
|
|
|
Args["phone", int, Field(completion=lambda: "请输入手机号")],
|
|
|
|
|
Args["at", [str, At], Field(completion=lambda: "请输入教师号")],
|
|
|
|
|
)
|
|
|
|
|
|
|
|
|
|
cmd = on_alconna(alc, comp_config={"lite": True}, skip_for_unmatch=False)
|
|
|
|
|
|
|
|
|
|
@cmd.handle()
|
|
|
|
|
async def handle(result: Arparma):
|
|
|
|
|
cmd.finish("添加成功")
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
此时,当用户输入 `添加教师` 时,会自动提示用户输入姓名,手机号和教师号,用户输入后会自动进入下一个提示:
|
|
|
|
|
|
|
|
|
|
<Messenger
|
|
|
|
|
msgs={[
|
|
|
|
|
{ position: "right", msg: "添加教师" },
|
|
|
|
|
{ position: "left", msg: "以下是建议的输入: \n- name: 请输入姓名" },
|
|
|
|
|
{ position: "right", msg: "foo" },
|
|
|
|
|
{ position: "left", msg: "以下是建议的输入: \n- phone: 请输入手机号" },
|
|
|
|
|
{ position: "right", msg: "12345" },
|
|
|
|
|
{ position: "left", msg: "以下是建议的输入: \n- at: 请输入教师号" },
|
|
|
|
|
{ position: "right", msg: "@me" },
|
|
|
|
|
{ position: "left", msg: "添加成功" },
|
|
|
|
|
]}
|
|
|
|
|
/>
|
|
|
|
|
|
|
|
|
|
补全会话配置如下:
|
|
|
|
|
|
|
|
|
|
```python
|
|
|
|
|
class CompConfig(TypedDict):
|
|
|
|
|
tab: NotRequired[str]
|
|
|
|
|
"""用于切换提示的指令的名称"""
|
|
|
|
|
enter: NotRequired[str]
|
|
|
|
|
"""用于输入提示的指令的名称"""
|
|
|
|
|
exit: NotRequired[str]
|
|
|
|
|
"""用于退出会话的指令的名称"""
|
|
|
|
|
timeout: NotRequired[int]
|
|
|
|
|
"""超时时间"""
|
|
|
|
|
hide_tabs: NotRequired[bool]
|
|
|
|
|
"""是否隐藏所有提示"""
|
|
|
|
|
hides: NotRequired[Set[Literal["tab", "enter", "exit"]]]
|
|
|
|
|
"""隐藏的指令"""
|
|
|
|
|
disables: NotRequired[Set[Literal["tab", "enter", "exit"]]]
|
|
|
|
|
"""禁用的指令"""
|
|
|
|
|
lite: NotRequired[bool]
|
|
|
|
|
"""是否使用简洁版本的补全会话(相当于同时配置 disables、hides、hide_tabs)"""
|
|
|
|
|
```

|
## 内置插件
|
|
|
|
|
|
|
|
|
|
类似于 Nonebot 本身提供的内置插件,`nonebot_plugin_alconna` 提供了两个内置插件:`echo` 和 `help`。
|
|
|
|
|
|
|
|
|
|
你可以用本插件的 `load_builtin_plugin(s)` 来加载它们:
|
|
|
|
|
|
|
|
|
|
```python
|
|
|
|
|
from nonebot_plugin_alconna import load_builtin_plugins
|
|
|
|
|
|
|
|
|
|
load_builtin_plugins("echo", "help")
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
其中 `help` 仅能列出所有 Alconna 指令。
|
|
|
|
|
|
|
|
|
|
<Messenger
|
|
|
|
|
msgs={[
|
|
|
|
|
{ position: "right", msg: "/帮助" },
|
|
|
|
|
{ position: "left", msg: "# 当前可用的命令有:\n 0 /echo : echo 指令\n 1 /help : 显示所有命令帮助\n# 输入'命令名 -h|--help' 查看特定命令的语法" },
|
|
|
|
|
{ position: "right", msg: "/echo [图片]" },
|
|
|
|
|
{ position: "left", msg: "[图片]" },
|
|
|
|
|
]}
|
|
|
|
|
/>
