开发一个平台适配器
AstrBot 支持以插件的形式接入平台适配器,你可以自行接入 AstrBot 没有的平台。如飞书、钉钉甚至是哔哩哔哩私信、Minecraft。
我们以一个平台 FakePlatform 为例展开讲解。
首先,在插件目录下新增 fake_platform_adapter.py 和 fake_platform_event.py 文件。前者主要是平台适配器的实现,后者是平台事件的定义。
平台适配器
假设 FakePlatform 的客户端 SDK 是这样:
import asyncio
class FakeClient():
'''模拟一个消息平台,这里 5 秒钟下发一个消息'''
def __init__(self, token: str, username: str):
self.token = token
self.username = username
# ...
async def start_polling(self):
while True:
await asyncio.sleep(5)
await getattr(self, 'on_message_received')({
'bot_id': '123',
'content': '新消息',
'username': 'zhangsan',
'userid': '123',
'message_id': 'asdhoashd',
'group_id': 'group123',
})
async def send_text(self, to: str, message: str):
print('发了消息:', to, message)
async def send_image(self, to: str, image_path: str):
print('发了消息:', to, image_path)
我们创建 fake_platform_adapter.py:
import asyncio
from astrbot.api.platform import Platform, AstrBotMessage, MessageMember, PlatformMetadata, MessageType
from astrbot.api.event import MessageChain
from astrbot.api.message_components import Plain, Image, Record # 消息链中的组件,可以根据需要导入
from astrbot.core.platform.astr_message_event import MessageSesion
from astrbot.api.platform import register_platform_adapter
from astrbot import logger
from .client import FakeClient
from .fake_platform_event import FakePlatformEvent
# 注册平台适配器。第一个参数为平台名,第二个为描述。第三个为默认配置。
@register_platform_adapter("fake", "fake 适配器", default_config_tmpl={
"token": "your_token",
"username": "bot_username"
})
class FakePlatformAdapter(Platform):
def __init__(self, platform_config: dict, platform_settings: dict, event_queue: asyncio.Queue) -> None:
super().__init__(event_queue)
self.config = platform_config # 上面的默认配置,用户填写后会传到这里
self.settings = platform_settings # platform_settings 平台设置。
async def send_by_session(self, session: MessageSesion, message_chain: MessageChain):
# 必须实现
await super().send_by_session(session, message_chain)
def meta(self) -> PlatformMetadata:
# 必须实现,直接像下面一样返回即可。
return PlatformMetadata(
"fake",
"fake 适配器",
)
async def run(self):
# 必须实现,这里是主要逻辑。
# FakeClient 是我们自己定义的,这里只是示例。这个是其回调函数
async def on_received(data):
logger.info(data)
abm = await self.convert_message(data=data) # 转换成 AstrBotMessage
await self.handle_msg(abm)
# 初始化 FakeClient
self.client = FakeClient(self.config['token'], self.config['username'])
self.client.on_message_received = on_received
await self.client.start_polling() # 持续监听消息,这是个堵塞方法。
async def convert_message(self, data: dict) -> AstrBotMessage:
# 将平台消息转换成 AstrBotMessage
# 这里就体现了适配程度,不同平台的消息结构不一样,这里需要根据实际情况进行转换。
abm = AstrBotMessage()
abm.type = MessageType.GROUP_MESSAGE # 还有 friend_message,对应私聊。具体平台具体分析。重要!
abm.group_id = data['group_id'] # 如果是私聊,这里可以不填
abm.message_str = data['content'] # 纯文本消息。重要!
abm.sender = MessageMember(user_id=data['userid'], nickname=data['username']) # 发送者。重要!
abm.message = [Plain(text=data['content'])] # 消息链。如果有其他类型的消息,直接 append 即可。重要!
abm.raw_message = data # 原始消息。
abm.self_id = data['bot_id']
abm.session_id = data['userid'] # 会话 ID。重要!
abm.message_id = data['message_id'] # 消息 ID。
return abm
async def handle_msg(self, message: AstrBotMessage):
# 处理消息
message_event = FakePlatformEvent(
message_str=message.message_str,
message_obj=message,
platform_meta=self.meta(),
session_id=message.session_id,
client=self.client
)
self.commit_event(message_event) # 提交事件到事件队列。不要忘记!
fake_platform_event.py:
from astrbot.api.event import AstrMessageEvent, MessageChain
from astrbot.api.platform import AstrBotMessage, PlatformMetadata
from astrbot.api.message_components import Plain, Image
from .client import FakeClient
from astrbot.core.utils.io import download_image_by_url
class FakePlatformEvent(AstrMessageEvent):
def __init__(self, message_str: str, message_obj: AstrBotMessage, platform_meta: PlatformMetadata, session_id: str, client: FakeClient):
super().__init__(message_str, message_obj, platform_meta, session_id)
self.client = client
async def send(self, message: MessageChain):
for i in message.chain: # 遍历消息链
if isinstance(i, Plain): # 如果是文字类型的
await self.client.send_text(to=self.get_sender_id(), message=i.text)
elif isinstance(i, Image): # 如果是图片类型的
img_url = i.file
img_path = ""
# 下面的三个条件可以直接参考一下。
if img_url.startswith("file:///"):
img_path = img_url[8:]
elif i.file and i.file.startswith("http"):
img_path = await download_image_by_url(i.file)
else:
img_path = img_url
# 请善于 Debug!
await self.client.send_image(to=self.get_sender_id(), image_path=img_path)
await super().send(message) # 需要最后加上这一段,执行父类的 send 方法。
最后,main.py 只需这样,在初始化的时候导入 fake_platform_adapter 模块。装饰器会自动注册。
from astrbot.api.star import Context, Star
class MyPlugin(Star):
def __init__(self, context: Context):
from .fake_platform_adapter import FakePlatformAdapter # noqa
搞好后,运行 AstrBot:
这里出现了我们创建的 fake。
启动后,可以看到正常工作:
