| # Alconna 插件 | ||||
|  | ||||
| 展示: | ||||
|  | ||||
| ```python | ||||
| from nonebot_plugin_alconna import At, Image, on_alconna | ||||
| from arclet.alconna import Args, Option, Alconna, Arparma, MultiVar, Subcommand | ||||
|  | ||||
|  | ||||
| alc = Alconna( | ||||
|     ["/", "!"], | ||||
|     "role-group", | ||||
|     Subcommand( | ||||
|         "add", | ||||
|         Args["name", str], | ||||
|         Option("member", Args["target", MultiVar(At)]), | ||||
|     ), | ||||
|     Option("list"), | ||||
|     Option("icon", Args["icon", Image]) | ||||
| ) | ||||
| rg = on_alconna(alc, auto_send_output=True) | ||||
|  | ||||
|  | ||||
| @rg.handle() | ||||
| async def _(result: Arparma): | ||||
|     if result.find("list"): | ||||
|         img: bytes = await gen_role_group_list_image() | ||||
|         await rg.finish(Image(raw=img)) | ||||
|     if result.find("add"): | ||||
|         group = await create_role_group(result.query[str]("add.name")) | ||||
|         if result.find("add.member"): | ||||
|             ats = result.query[tuple[At, ...]]("add.member.target") | ||||
|             group.extend(member.target for member in ats) | ||||
|         await rg.finish("添加成功") | ||||
| ``` | ||||
|  | ||||
| ## 响应器使用 | ||||
|  | ||||
| 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`: | ||||
|  | ||||
| ```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, | ||||
|     ..., | ||||
| ): | ||||
| ``` | ||||
|  | ||||
| - `command`: Alconna 命令或字符串,字符串将通过 `AlconnaFormat` 转换为 Alconna 命令 | ||||
| - `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 | ||||
| - `aliases`: 命令别名, 作用类似于 `on_command` 中的 aliases | ||||
| - `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 | ||||
|  | ||||
| `on_alconna` 返回的是 `Matcher` 的子类 `AlconnaMatcher` ,其拓展了如下方法: | ||||
|  | ||||
| - `.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 | ||||
|  | ||||
| 实例: | ||||
|  | ||||
| ```python | ||||
| from nonebot import require | ||||
| require("nonebot_plugin_alconna") | ||||
|  | ||||
| from arclet.alconna import Alconna, Option, Args | ||||
| from nonebot_plugin_alconna import on_alconna, Match, UniMessage | ||||
|  | ||||
|  | ||||
| login = on_alconna(Alconna(["/"], "login", Args["password?", str], Option("-r|--recall"))) # 这里["/"]指命令前缀必须是/ | ||||
|  | ||||
| # /login -r 触发 | ||||
| @login.assign("recall") | ||||
| async def login_exit(): | ||||
|     await login.finish("已退出") | ||||
|  | ||||
| # /login xxx 触发 | ||||
| @login.assign("password") | ||||
| async def login_handle(pw: Match[str]): | ||||
|     if pw.available: | ||||
|         login.set_path_arg("password", pw.result) | ||||
|  | ||||
| # /login 触发 | ||||
| @login.got_path("password", prompt=UniMessage.template("{:At(user, $event.get_user_id())} 请输入密码")) | ||||
| async def login_got(password: str): | ||||
| 	assert password | ||||
| 	await login.send("登录成功") | ||||
| ``` | ||||
|  | ||||
| ## 依赖注入 | ||||
|  | ||||
| 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: | ||||
|  | ||||
| - `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 | ||||
|  | ||||
| 同时,基于 [`Annotated` 支持](https://github.com/nonebot/nonebot2/pull/1832),添加了两类注解: | ||||
|  | ||||
| - `AlcMatches`:同 `AlconnaMatches` | ||||
| - `AlcResult`:同 `AlconnaResult` | ||||
|  | ||||
| 可以看到,本插件提供了几类额外的模型: | ||||
|  | ||||
| - `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 | ||||
|  | ||||
| **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: | ||||
|  | ||||
| ```python | ||||
| async def handle( | ||||
|     result: CommandResult, | ||||
|     arp: Arparma, | ||||
|     dup: Duplication, | ||||
|     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 | ||||
| ): | ||||
|     ... | ||||
| ``` | ||||
|  | ||||
| :::note | ||||
|  | ||||
| 如果你更喜欢 Depends 式的依赖注入,`nonebot_plugin_alconna` 同时提供了一系列的依赖注入函数,他们包括: | ||||
|  | ||||
| - `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,其能够额外传入一个 middleware 函数来处理得到的参数 | ||||
| - `AlconnaQuery`: `Query` 类型的依赖注入函数,其能够额外传入一个 middleware 函数来处理得到的参数 | ||||
| - `AlconnaExecResult`: 提供挂载在命令上的 callback 的返回结果 (`Dict[str, Any]`) 的依赖注入函数 | ||||
| - `AlconnaExtension`: 提供指定类型的 `Extension` 的依赖注入函数 | ||||
|  | ||||
| ::: | ||||
|  | ||||
| 实例: | ||||
|  | ||||
| ```python | ||||
| from nonebot import require | ||||
| require("nonebot_plugin_alconna") | ||||
|  | ||||
| from nonebot_plugin_alconna import ( | ||||
|     on_alconna, | ||||
|     Match, | ||||
|     Query, | ||||
|     AlconnaMatch, | ||||
|     AlcResult | ||||
| ) | ||||
| from arclet.alconna import Alconna, Args, Option, Arparma | ||||
|  | ||||
|  | ||||
| test = on_alconna( | ||||
|     Alconna( | ||||
|         "test", | ||||
|         Option("foo", Args["bar", int]), | ||||
|         Option("baz", Args["qux", bool, False]) | ||||
|     ), | ||||
|     auto_send_output=True | ||||
| ) | ||||
|  | ||||
| @test.handle() | ||||
| async def handle_test1(result: AlcResult): | ||||
|     await test.send(f"matched: {result.matched}") | ||||
|     await test.send(f"maybe output: {result.output}") | ||||
|  | ||||
| @test.handle() | ||||
| async def handle_test2(result: Arparma): | ||||
|     await test.send(f"head result: {result.header_result}") | ||||
|     await test.send(f"args: {result.all_matched_args}") | ||||
|  | ||||
| @test.handle() | ||||
| async def handle_test3(bar: Match[int] = AlconnaMatch("bar")): | ||||
|     if bar.available: | ||||
|         await test.send(f"foo={bar.result}") | ||||
|  | ||||
| @test.handle() | ||||
| async def handle_test4(qux: Query[bool] = Query("baz.qux", False)): | ||||
|     if qux.available: | ||||
|         await test.send(f"baz.qux={qux.result}") | ||||
| ``` | ||||
|  | ||||
| ## 多平台适配 | ||||
|  | ||||
| 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 | ||||
|  | ||||
| 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。 | ||||
|  | ||||
| 具体介绍和使用请查看 [通用信息组件](./uniseg.mdx#通用消息段) | ||||
|  | ||||
| 本插件为以下适配器提供了专门的适配器标注: | ||||

|  | ||||
| ## 条件控制 | ||||
|  | ||||
| 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。 | ||||
|  | ||||
| ```python | ||||
| ... | ||||
| from nonebot import require | ||||
| require("nonebot_plugin_alconna") | ||||
| ... | ||||
|  | ||||
| from arclet.alconna import Alconna, Subcommand, Option, Args | ||||
| from nonebot_plugin_alconna import on_alconna, CommandResult | ||||
|  | ||||
|  | ||||
| pip = Alconna( | ||||
|     "pip", | ||||
|     Subcommand( | ||||
|         "install", Args["pak", str], | ||||
|         Option("--upgrade"), | ||||
|         Option("--force-reinstall") | ||||
|     ), | ||||
|     Subcommand("list", Option("--out-dated")) | ||||
| ) | ||||
|  | ||||
| pip_cmd = on_alconna(pip) | ||||
|  | ||||
| # 仅在命令为 `pip install pip` 时响应 | ||||
| @pip_cmd.assign("install.pak", "pip") | ||||
| async def update(res: CommandResult): | ||||
|     ... | ||||
|  | ||||
| # 仅在命令为 `pip list` 时响应 | ||||
| @pip_cmd.assign("list") | ||||
| async def list_(res: CommandResult): | ||||
|     ... | ||||
|  | ||||
| # 在命令为 `pip install xxx` 时响应 | ||||
| @pip_cmd.assign("install") | ||||
| async def install(res: CommandResult): | ||||
|     ... | ||||
| ``` | ||||
|  | ||||
| 此外,使用 `AlconnaMatcher.dispatch` 还能像 `CommandGroup` 一样为每个分发设置独立的 matcher: | ||||
|  | ||||
| ```python | ||||
| update_cmd = pip_cmd.dispatch("install.pak", "pip") | ||||
|  | ||||
| @update_cmd.handle() | ||||
| async def update(arp: CommandResult): | ||||
|     ... | ||||
| ``` | ||||
|  | ||||
| 另外,`AlconnaMatcher` 有类似于 `got` 的 `got_path`: | ||||
|  | ||||
| ```python | ||||
| from nonebot_plugin_alconna import At, Match, UniMessage, on_alconna | ||||
|  | ||||
|  | ||||
| test_cmd = on_alconna(Alconna("test", Args["target?", Union[str, At]])) | ||||
|  | ||||
| @test_cmd.handle() | ||||
| async def tt_h(target: Match[Union[str, At]]): | ||||
|     if target.available: | ||||
|         test_cmd.set_path_arg("target", target.result) | ||||
|  | ||||
| @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])) | ||||
| ``` | ||||
|  | ||||
| `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) | ||||
|  | ||||
| `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。 | ||||
|  | ||||
| :::tip | ||||
|  | ||||
| `path` 支持 ~XXX 语法,其会把 ~ 替换为可能的父级路径: | ||||
|  | ||||
| ```python | ||||
|  pip = Alconna( | ||||
|      "pip", | ||||
|      Subcommand( | ||||
|          "install", | ||||
|          Args["pak", str], | ||||
|          Option("--upgrade|-U"), | ||||
|          Option("--force-reinstall"), | ||||
|      ), | ||||
|      Subcommand("list", Option("--out-dated")), | ||||
|  ) | ||||
|  | ||||
|  pipcmd = on_alconna(pip) | ||||
|  pip_install_cmd = pipcmd.dispatch("install") | ||||
|  | ||||
|  | ||||
|  @pip_install_cmd.assign("~upgrade") | ||||
|  async def pip1_u(pak: Query[str] = Query("~pak")): | ||||
|      await pip_install_cmd.finish(f"pip upgrading {pak.result}...") | ||||
| ``` | ||||
|  | ||||
| ::: | ||||
|  | ||||
| ## 响应器创建装饰 | ||||
|  | ||||
| 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: | ||||
|  | ||||
| ```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 | ||||
|  | ||||
| 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** : | ||||
|  | ||||
| ```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)) | ||||
| ``` | ||||
|  | ||||
| 甚至,你可以设置 `action` 来设定响应行为: | ||||
|  | ||||
| ```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() | ||||
| ) | ||||
| ``` | ||||
|  | ||||
| ## 返回值中间件 | ||||
|  | ||||
| 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: | ||||
|  | ||||
| ```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) | ||||
| ``` | ||||
|  | ||||
| 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 | ||||
|  | ||||
| 本插件提供了一个 `Extension` 类,其用于自定义 AlconnaMatcher 的部分行为 | ||||
|  | ||||
| 例如一个 `LLMExtension` 可以如下实现 (仅举例): | ||||
|  | ||||
| ```python | ||||
| from nonebot_plugin_alconna import Extension, Alconna, on_alconna, Interface | ||||
|  | ||||
|  | ||||
| class LLMExtension(Extension): | ||||
|     @property | ||||
|     def priority(self) -> int: | ||||
|         return 10 | ||||
|  | ||||
|     @property | ||||
|     def id(self) -> str: | ||||
|         return "LLMExtension" | ||||
|  | ||||
|     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) | ||||
|  | ||||
|     def before_catch(self, name, annotation, default): | ||||
|         return name == "llm" | ||||
|  | ||||
|     def catch(self, interface: Interface): | ||||
|         if interface.name == "llm": | ||||
|             return self.llm | ||||
|  | ||||
| matcher = on_alconna( | ||||
|     Alconna(...), | ||||
|     extensions=[LLMExtension(LLM)] | ||||
| ) | ||||
| ... | ||||
| ``` | ||||
|  | ||||
| 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。 | ||||
|  | ||||
| 目前 `Extension` 的功能有: | ||||
|  | ||||
| - `validate`: 对于事件的来源适配器或 bot 选择是否接受响应 | ||||
| - `output_converter`: 输出信息的自定义转换方法 | ||||
| - `message_provider`: 从传入事件中自定义提取消息的方法 | ||||
| - `receive_provider`: 对传入的消息 (Message 或 UniMessage) 的额外处理 | ||||
| - `context_provider`: 对命令上下文的额外处理 | ||||
| - `permission_check`: 命令对消息解析并确认头部匹配(即确认选择响应)时对发送者的权限判断 | ||||
| - `parse_wrapper`: 对命令解析结果的额外处理 | ||||
| - `send_wrapper`: 对发送的消息 (Message 或 UniMessage) 的额外处理 | ||||
| - `before_catch`: 自定义依赖注入的绑定确认函数 | ||||
| - `catch`: 自定义依赖注入处理函数 | ||||
| - `post_init`: 响应器创建后对命令对象的额外处理 | ||||
|  | ||||
| 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: | ||||
|  | ||||
| ```python | ||||
| from nonebot_plugin_alconna import Match, on_alconna | ||||
| from nonebot_plugin_alconna.builtins.extensions.discord import DiscordSlashExtension | ||||
|  | ||||
|  | ||||
| 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}") | ||||
| ``` | ||||
|  | ||||
| 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。 | ||||
|  | ||||
| :::tip | ||||
|  | ||||
| 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]" }, | ||||
|   ]} | ||||
| /> | ||||
