# 通用消息组件
|
|
|
|
|
|
|
|
|
|
`uniseg` 模块属于 `nonebot-plugin-alconna` 的子插件,其提供了一套通用的消息组件,用于在 `nonebot-plugin-alconna` 下构建通用消息。
|
|
|
|
|
|
|
|
|
|
## 通用消息段
|
|
|
|
|
|
2024-02-09 14:48:48 +08:00
|
|
|
|
适配器下的消息段标注会匹配适配器特定的 `MessageSegment`, 而通用消息段与适配器消息段的区别在于:
|
|
|
|
|
通用消息段会匹配多个适配器中相似类型的消息段,并返回 `uniseg` 模块中定义的 [`Segment` 模型](https://nonebot.dev/docs/next/best-practice/alconna/utils#%E9%80%9A%E7%94%A8%E6%B6%88%E6%81%AF%E6%AE%B5), 以达到**跨平台接收消息**的作用。
|
|
|
|
|
|
2023-10-07 12:06:07 +08:00
|
|
|
|
`nonebot-plugin-alconna.uniseg` 提供了类似 `MessageSegment` 的通用消息段,并可在 `Alconna` 下直接标注使用:
|
|
|
|
|
|
|
|
|
|
```python
|
|
|
|
|
class Segment:
|
|
|
|
|
"""基类标注"""
|
|
|
|
|
|
|
|
|
|
class Text(Segment):
|
|

|
|
|
"""AtAll对象, 表示一类提醒所有人的元素"""
|
|
|
|
|
|
|
|
|
|
class Emoji(Segment):
|
|
|
|
|
"""Emoji对象, 表示一类表情元素"""
|
|
|
|
|
id: str
|
|
|
|
|

|

|
|
|

2023-10-07 12:06:07 +08:00
|
|
|
|
|
|
|
|
|
class Card(Segment):
|
|
|
|
|
type: Literal["xml", "json"]
|
|
|
|
|
raw: str
|
|
|
|
|
|
|
|
|
|
class Other(Segment):
|
|
|
|
|
"""其他 Segment"""
|
|
|
|
|
```
|
|
|
|
|
|
2024-02-09 14:48:48 +08:00
|
|
|
|
此类消息段通过 `UniMessage.export` 可以转为特定的 `MessageSegment`
|
2023-10-07 12:06:07 +08:00
|
|
|
|
|
|
|
|
|
## 通用消息序列
|
|
|
|
|
|
|
|
|
|
`nonebot-plugin-alconna.uniseg` 同时提供了一个类似于 `Message` 的 `UniMessage` 类型,其元素为经过通用标注转换后的通用消息段。
|
|
|
|
|
|
2024-02-09 14:48:48 +08:00
|
|
|
|
你可以用如下方式获取 `UniMessage`:
|
2023-11-07 14:39:05 +08:00
|
|
|
|
|
|
|
|
|
<Tabs groupId="get_unimsg">
|
|
|
|
|
<TabItem value="depend" label="使用依赖注入">
|
|
|
|
|
|
|
|
|
|
通过提供的 `UniversalMessage` 或 `UniMsg` 依赖注入器来获取 `UniMessage`。
|
2023-10-07 12:06:07 +08:00
|
|
|
|
|
|
|
|
|
```python
|
|
|
|
|
from nonebot_plugin_alconna.uniseg import UniMsg, At, Reply
|
|
|
|
|
|
2024-02-09 14:48:48 +08:00
|
|
|
|
|
2023-10-07 12:06:07 +08:00
|
|
|
|
matcher = on_xxx(...)
|
|
|
|
|
|
|
|
|
|
@matcher.handle()
|
|
|
|
|
async def _(msg: UniMsg):
|
|
|
|
|
reply = msg[Reply, 0]
|
|
|
|
|
print(reply.origin)
|
|
|
|
|
if msg.has(At):
|
|
|
|
|
ats = msg.get(At)
|
|
|
|
|
print(ats)
|
|
|
|
|
...
|
|
|
|
|
```
|
|
|
|
|
|
2023-11-07 14:39:05 +08:00
|
|
|
|
</TabItem>
|
|
|
|
|
<TabItem value="method" label="使用 UniMessage.generate">
|
|
|
|
|
|
|
|
|
|
注意,`generate` 方法在响应器以外的地方如果不传入 `event` 与 `bot` 则无法处理 reply。
|
|
|
|
|
|
|
|
|
|
```python
|
|
|
|
|
from nonebot import Message, EventMessage
|
|
|
|
|
from nonebot_plugin_alconna.uniseg import UniMessage
|
|
|
|
|
|
2024-02-09 14:48:48 +08:00
|
|
|
|
|
2023-11-07 14:39:05 +08:00
|
|
|
|
matcher = on_xxx(...)
|
|
|
|
|
|
|
|
|
|
@matcher.handle()
|
|
|
|
|
async def _(message: Message = EventMessage()):
|
|
|
|
|
msg = await UniMessage.generate(message=message)
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
</TabItem>
|
|
|
|
|
</Tabs>
|
2023-10-07 12:06:07 +08:00
|
|
|
|
|
2023-11-07 14:39:05 +08:00
|
|
|
|
不仅如此,你还可以通过 `UniMessage` 的 `export` 与 `send` 方法来**跨平台发送消息**。
|
|
|
|
|
|
2024-02-09 14:48:48 +08:00
|
|
|
|
`UniMessage.export` 会通过传入的 `bot: Bot` 参数,或上下文中的 `Bot` 对象读取适配器信息,并使用对应的生成方法把通用消息转为适配器对应的消息序列:
|
2023-10-07 12:06:07 +08:00
|
|
|
|
|
|
|
|
|
```python
|
|
|
|
|
from nonebot import Bot, on_command
|
|
|
|
|
from nonebot_plugin_alconna.uniseg import Image, UniMessage
|
|
|
|
|
|
2024-02-09 14:48:48 +08:00
|
|
|
|
|
2023-10-07 12:06:07 +08:00
|
|
|
|
test = on_command("test")
|
|
|
|
|
|
|
|
|
|
@test.handle()
|
2023-11-07 14:39:05 +08:00
|
|
|
|
async def handle_test():
|
|
|
|
|
await test.send(await UniMessage(Image(path="path/to/img")).export())
|
2023-10-07 12:06:07 +08:00
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
而在 `AlconnaMatcher` 下,`got`, `send`, `reject` 等可以发送消息的方法皆支持使用 `UniMessage`,不需要手动调用 export 方法:
|
|
|
|
|
|
|
|
|
|
```python
|
|
|
|
|
from arclet.alconna import Alconna, Args
|
|
|
|
|
from nonebot_plugin_alconna import Match, AlconnaMatcher, on_alconna
|
|
|
|
|
from nonebot_plugin_alconna.uniseg import At, UniMessage
|
|
|
|
|
|
2024-02-09 14:48:48 +08:00
|
|
|
|
|
2023-10-07 12:06:07 +08:00
|
|
|
|
test_cmd = on_alconna(Alconna("test", Args["target?", At]))
|
|
|
|
|
|
|
|
|
|
@test_cmd.handle()
|
|
|
|
|
async def tt_h(matcher: AlconnaMatcher, target: Match[At]):
|
|
|
|
|
if target.available:
|
|
|
|
|
matcher.set_path_arg("target", target.result)
|
|
|
|
|
|
|
|
|
|
@test_cmd.got_path("target", prompt="请输入目标")
|
|
|
|
|
async def tt(target: At):
|
|
|
|
|
await test_cmd.send(UniMessage([target, "\ndone."]))
|
|
|
|
|
```
|
|
|
|
|
|
2023-11-07 14:39:05 +08:00
|
|
|
|
除此之外 `UniMessage.send` 方法基于 `UniMessage.export` 并调用各适配器下的发送消息方法,返回一个 `Receipt` 对象,用于修改/撤回消息:
|
|
|
|
|
|
|
|
|
|
```python
|
|
|
|
|
from nonebot import Bot, on_command
|
|
|
|
|
from nonebot_plugin_alconna.uniseg import UniMessage
|
|
|
|
|
|
2024-02-09 14:48:48 +08:00
|
|
|
|
|
2023-11-07 14:39:05 +08:00
|
|
|
|
test = on_command("test")
|
|
|
|
|
|
|
|
|
|
@test.handle()
|
|
|
|
|
async def handle():
|
|
|
|
|
receipt = await UniMessage.text("hello!").send(at_sender=True, reply_to=True)
|
|
|
|
|
await receipt.recall(delay=1)
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
:::caution
|
|
|
|
|
|
|
|
|
|
在响应器以外的地方,`bot` 参数必须手动传入。
|
|
|
|
|
|
|
|
|
|
:::
|
|
|
|
|
|
|
|
|
|
### 构造
|
|
|
|
|
|
|
|
|
|
如同 `Message`, `UniMessage` 可以传入单个字符串/消息段,或可迭代的字符串/消息段:
|
|
|
|
|
|
|
|
|
|
```python
|
|
|
|
|
from nonebot_plugin_alconna.uniseg import UniMessage, At
|
|
|
|
|
|
2024-02-09 14:48:48 +08:00
|
|
|
|
|
2023-11-07 14:39:05 +08:00
|
|
|
|
msg = UniMessage("Hello")
|
|
|
|
|
msg1 = UniMessage(At("user", "124"))
|
|
|
|
|
msg2 = UniMessage(["Hello", At("user", "124")])
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
`UniMessage` 上同时存在便捷方法,令其可以链式地添加消息段:
|
|
|
|
|
|
|
|
|
|
```python
|
|
|
|
|
from nonebot_plugin_alconna.uniseg import UniMessage, At, Image
|
|
|
|
|
|
2024-02-09 14:48:48 +08:00
|
|
|
|
|
2023-11-07 14:39:05 +08:00
|
|
|
|
msg = UniMessage.text("Hello").at("124").image(path="/path/to/img")
|
|
|
|
|
assert msg == UniMessage(
|
|
|
|
|
["Hello", At("user", "124"), Image(path="/path/to/img")]
|
|
|
|
|
)
|
|
|
|
|
```
|
|
|
|
|
|
2023-10-07 12:06:07 +08:00
|
|
|
|
### 拼接消息
|
|
|
|
|
|
2024-02-09 14:48:48 +08:00
|
|
|
|
`str`、`UniMessage`、`Segment` 对象之间可以直接相加,相加均会返回一个新的 `UniMessage` 对象:
|
2023-10-07 12:06:07 +08:00
|
|
|
|
|
|
|
|
|
```python
|
|
|
|
|
# 消息序列与消息段相加
|
|
|
|
|
UniMessage("text") + Text("text")
|
|
|
|
|
# 消息序列与字符串相加
|
|
|
|
|
UniMessage([Text("text")]) + "text"
|
|
|
|
|
# 消息序列与消息序列相加
|
|
|
|
|
UniMessage("text") + UniMessage([Text("text")])
|
|
|
|
|
# 字符串与消息序列相加
|
|
|
|
|
"text" + UniMessage([Text("text")])
|
|
|
|
|
# 消息段与消息段相加
|
|
|
|
|
Text("text") + Text("text")
|
|
|
|
|
# 消息段与字符串相加
|
|
|
|
|
Text("text") + "text"
|
|
|
|
|
# 消息段与消息序列相加
|
|
|
|
|
Text("text") + UniMessage([Text("text")])
|
|
|
|
|
# 字符串与消息段相加
|
|
|
|
|
"text" + Text("text")
|
|
|
|
|
```
|
|
|
|
|
|
2024-02-09 14:48:48 +08:00
|
|
|
|
如果需要在当前消息序列后直接拼接新的消息段,可以使用 `Message.append`、`Message.extend` 方法,或者使用自加:
|
2023-10-07 12:06:07 +08:00
|
|
|
|
|
|
|
|
|
```python
|
|
|
|
|
msg = UniMessage([Text("text")])
|
|
|
|
|
# 自加
|
|
|
|
|
msg += "text"
|
|
|
|
|
msg += Text("text")
|
|
|
|
|
msg += UniMessage([Text("text")])
|
|
|
|
|
# 附加
|
|
|
|
|
msg.append(Text("text"))
|
|
|
|
|
# 扩展
|
|
|
|
|
msg.extend([Text("text")])
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
### 使用消息模板
|
|
|
|
|
|
2024-02-09 14:48:48 +08:00
|
|
|
|
`UniMessage.template` 同样类似于 `Message.template`,可以用于格式化消息,大体用法参考 [消息模板](../../tutorial/message#使用消息模板)。
|
2023-10-07 12:06:07 +08:00
|
|
|
|
|
|
|
|
|
这里额外说明 `UniMessage.template` 的拓展控制符
|
|
|
|
|
|
|
|
|
|
相比 `Message`,UniMessage 对于 {:XXX} 做了另一类拓展。其能够识别例如 At(xxx, yyy) 或 Emoji(aaa, bbb)的字符串并执行
|
|
|
|
|
|
|
|
|
|
以 At(...) 为例:
|
|
|
|
|
|
|
|
|
|
```python title=使用通用消息段的拓展控制符
|
|
|
|
|
>>> from nonebot_plugin_alconna.uniseg import UniMessage
|
|
|
|
|
>>> UniMessage.template("{:At(user, target)}").format(target="123")
|
|
|
|
|
UniMessage(At("user", "123"))
|
|
|
|
|
>>> UniMessage.template("{:At(type=user, target=id)}").format(id="123")
|
|
|
|
|
UniMessage(At("user", "123"))
|
|
|
|
|
>>> UniMessage.template("{:At(type=user, target=123)}").format()
|
|
|
|
|
UniMessage(At("user", "123"))
|
|
|
|
|
```
|
|
|
|
|
|
2024-02-09 14:48:48 +08:00
|
|
|
|
而在 `AlconnaMatcher` 中,{:XXX} 更进一步地提供了获取 `event` 和 `bot` 中的属性的功能:

|
|
|
|
|
2023-11-07 14:39:05 +08:00
|
|
|
|
```python title=在AlconnaMatcher中使用通用消息段的拓展控制符
|
2023-10-07 12:06:07 +08:00
|
|
|
|
from arclet.alconna import Alconna, Args
|
|
|
|
|
from nonebot_plugin_alconna import At, Match, UniMessage, AlconnaMatcher, on_alconna
|
|
|
|
|

test_cmd = on_alconna(Alconna("test", Args["target?", At]))
|
|
|
|
|
|
|
|
|
|
@test_cmd.handle()
|
|
|
|
|
async def tt_h(matcher: AlconnaMatcher, target: Match[At]):
|
|
|
|
|
if target.available:
|
|
|
|
|
matcher.set_path_arg("target", target.result)
|
|
|
|
|
|
|
|
|
|
@test_cmd.got_path(

"target",
|
|
|
|
|
prompt=UniMessage.template("{:At(user, $event.get_user_id())} 请确认目标")
|
|
|
|
|
)
|
|
|
|
|
async def tt():
|
|
|
|
|
await test_cmd.send(
|
|
|
|
|
UniMessage.template("{:At(user, $event.get_user_id())} 已确认目标为 {target}")
|

)
|

```

### 检查消息段
|
|
|
|
|
|
|
|
|
|
我们可以通过 `in` 运算符或消息序列的 `has` 方法来:
|
|
|
|
|
|
|
|
|
|
```python
|
|
|
|
|
# 是否存在消息段
|
|
|
|
|
At("user", "1234") in message
|
|
|
|
|
# 是否存在指定类型的消息段
|
|
|
|
|
At in message
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
我们还可以使用 `only` 方法来检查消息中是否仅包含指定的消息段:
|
|
|
|
|
|
|
|
|
|
```python
|
|
|
|
|
# 是否都为 "test"
|
|
|
|
|
message.only("test")
|
|
|
|
|
# 是否仅包含指定类型的消息段
|
|
|
|
|
message.only(Text)
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
### 获取消息纯文本
|
|
|
|
|
|
|
|
|
|
类似于 `Message.extract_plain_text()`,用于获取通用消息的纯文本:
|
|
|
|
|
|
|
|
|
|
```python
|
|
|
|
|
from nonebot_plugin_alconna.uniseg import UniMessage, At
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
# 提取消息纯文本字符串
|
|
|
|
|
assert UniMessage(
|
|
|
|
|
[At("user", "1234"), "text"]
|
|
|
|
|
).extract_plain_text() == "text"
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
### 遍历
|
|
|
|
|
|
|
|
|
|
通用消息序列继承自 `List[Segment]` ,因此可以使用 `for` 循环遍历消息段:
|
|
|
|
|
|
|
|
|
|
```python
|
|
|
|
|
for segment in message: # type: Segment
|
|
|
|
|
...
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
### 过滤、索引与切片
|
|
|
|
|
|
|
|
|
|
消息序列对列表的索引与切片进行了增强,在原有列表 `int` 索引与 `slice` 切片的基础上,支持 `type` 过滤索引与切片:
|
|
|
|
|
|
|
|
|
|
```python
|
|
|
|
|
from nonebot_plugin_alconna.uniseg import UniMessage, At, Text, Reply
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
message = UniMessage(
|
|
|
|
|
[
|
|
|
|
|
Reply(...),
|
|
|
|
|
"text1",
|
|
|
|
|
At("user", "1234"),
|
|
|
|
|
"text2"
|
|
|
|
|
]
|
|
|
|
|
)
|
|
|
|
|
# 索引
|
|
|
|
|
message[0] == Reply(...)
|
|
|
|
|
# 切片
|
|
|
|
|
message[0:2] == UniMessage([Reply(...), Text("text1")])
|
|
|
|
|
# 类型过滤
|
|
|
|
|
message[At] == Message([At("user", "1234")])
|
|
|
|
|
# 类型索引
|
|
|
|
|
message[At, 0] == At("user", "1234")
|
|
|
|
|
# 类型切片
|
|
|
|
|
message[Text, 0:2] == UniMessage([Text("text1"), Text("text2")])
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
我们也可以通过消息序列的 `include`、`exclude` 方法进行类型过滤:
|
|
|
|
|
|
|
|
|
|
```python
|
|
|
|
|
message.include(Text, At)
|
|
|
|
|
message.exclude(Reply)
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
同样的,消息序列对列表的 `index`、`count` 方法也进行了增强,可以用于索引指定类型的消息段:
|
|
|
|
|
|
|
|
|
|
```python
|
|
|
|
|
# 指定类型首个消息段索引
|
|
|
|
|
message.index(Text) == 1
|
|
|
|
|
# 指定类型消息段数量
|
|
|
|
|
message.count(Text) == 2
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
此外,消息序列添加了一个 `get` 方法,可以用于获取指定类型指定个数的消息段:
|
|
|
|
|
|
|
|
|
|
```python
|
|
|
|
|
# 获取指定类型指定个数的消息段
|
|
|
|
|
message.get(Text, 1) == UniMessage([Text("test1")])
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
### 消息发送
|
2023-11-07 14:39:05 +08:00
|
|
|
|
|
|
|
|
|
前面提到,通用消息可用 `UniMessage.send` 发送自身:
|
|
|
|
|
|
|
|
|
|
```python
|
|
|
|
|
async def send(
|
|
|
|
|
self,
|
|
|
|
|
target: Union[Event, Target, None] = None,
|
|
|
|
|
bot: Optional[Bot] = None,
|
|
|
|
|
fallback: bool = True,
|
|
|
|
|
at_sender: Union[str, bool] = False,
|
|
|
|
|
reply_to: Union[str, bool] = False,
|
|
|
|
|
) -> Receipt:
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
实际上,`UniMessage` 同时提供了获取消息事件 id 与消息发送对象的方法:
|
|
|
|
|
|
|
|
|
|
```python
|
|
|
|
|
from nonebot import Event, Bot
|
|
|
|
|
from nonebot_plugin_alconna.uniseg import UniMessage, Target
|
|
|
|
|
|
2024-02-09 14:48:48 +08:00
|
|
|
|
|
2023-11-07 14:39:05 +08:00
|
|
|
|
matcher = on_xxx(...)
|
|
|
|
|
|
|
|
|
|
@matcher.handle()
|
|
|
|
|
asycn def _(bot: Bot, event: Event):
|
|
|
|
|
target: Target = UniMessage.get_target(event, bot)
|
|
|
|
|
msg_id: str = UniMessage.get_message_id(event, bot)
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
`send`, `get_target`, `get_message_id` 中与 `event`, `bot` 相关的参数都会尝试从上下文中获取对象。
|
|
|
|
|
|
|
|
|
|
其中,`Target`:
|
|
|
|
|
|
|
|
|
|
```python
|
|
|
|
|
class Target:
|
|
|
|
|
id: str
|
|
|
|
|
"""目标id;若为群聊则为group_id或者channel_id,若为私聊则为user_id"""
|
|
|
|
|
parent_id: str = ""
|
|
|
|
|
"""父级id;若为频道则为guild_id,其他情况为空字符串"""
|
|
|
|
|
channel: bool = False
|
|
|
|
|
"""是否为频道,仅当目标平台同时支持群聊和频道时有效"""
|
|
|
|
|
private: bool = False
|
|
|
|
|
"""是否为私聊"""
|
|
|
|
|
source: str = ""
|
|
|
|
|
"""可能的事件id"""
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
是用来描述响应消息时的发送对象。
|
|
|
|
|
|
|
|
|
|
同样的,你可以通过依赖注入的方式在响应器中直接获取它们。
