# MoviePilot V2 插件开发指南
|
||
|
||
本指南详细介绍了如何开发适用于MoviePilot V2版本的插件,并实现插件的多版本兼容性,同时包括了服务封装类的使用示例,帮助开发者快速升级插件至V2版本。
|
||
|
||
## 1. 多版本插件开发与兼容性
|
||
|
||
### 1.1 开发V2版本的插件
|
||
|
||
要开发适用于MoviePilot V2版本的插件,并实现多版本兼容性,请按照以下步骤操作:
|
||
|
||
1. **目录结构调整**:
|
||
- 将插件代码放置在`plugins.v2`文件夹中。
|
||
- 将插件的定义放置在`package.v2.json`中,以实现该插件仅在MoviePilot V2版本中可见。
|
||
|
||
2. **插件定义示例**:
|
||
```json
|
||
{
|
||
"CustomSites": {
|
||
"name": "自定义站点",
|
||
"description": "增加自定义站点为签到和统计使用。",
|
||
"labels": "站点",
|
||
"version": "1.0",
|
||
"icon": "world.png",
|
||
"author": "lightolly",
|
||
"level": 2
|
||
}
|
||
}
|
||
```
|
||
|
||
3. **版本判断**:
|
||
- MoviePilot V2中 Settings 模块新增了`VERSION_FLAG`属性,V2版本值为`v2`,可通过以下代码判断当前的版本,以便在插件中兼容处理:
|
||
|
||
```python
|
||
from app.core.config import settings
|
||
|
||
if hasattr(settings, 'VERSION_FLAG'):
|
||
version = settings.VERSION_FLAG # V2
|
||
else:
|
||
version = "v1"
|
||
```
|
||
|
||
### 1.2 实现插件多版本兼容
|
||
|
||
如果V1版本插件在V2版本中实际可用,或在插件中主动兼容了V1和V2版本,则可以在`package.json`中定义 `"v2": true`属性,以便在MoviePilot V2版本插件市场中显示。
|
||
|
||
```json
|
||
{
|
||
"CustomSites": {
|
||
"name": "自定义站点",
|
||
"description": "增加自定义站点为签到和统计使用。",
|
||
"labels": "站点",
|
||
"version": "1.0",
|
||
"icon": "world.png",
|
||
"author": "lightolly",
|
||
"level": 2,
|
||
"v2": true
|
||
}
|
||
}
|
||
```
|
||
|
||
- **目录结构示例**:
|
||
```
|
||
plugins/
|
||
├── customsites/
|
||
│ ├── __init__.py
|
||
│ └── ...
|
||
plugins.v2/
|
||
├── customsites/
|
||
│ ├── __init__.py
|
||
│ └── ...
|
||
package.json
|
||
package.v2.json
|
||
```
|
||
|
||
- **插件代码中实现版本兼容**:
|
||
|
||
在插件代码中,可以根据`version`变量执行不同的逻辑,以适应不同的MoviePilot版本。
|
||
|
||
```python
|
||
from app.core.config import settings
|
||
|
||
class MyPlugin:
|
||
def init_plugin(self, config: dict = None):
|
||
if hasattr(settings, 'VERSION_FLAG'):
|
||
version = settings.VERSION_FLAG # V2
|
||
else:
|
||
version = "v1"
|
||
|
||
if version == "v2":
|
||
self.setup_v2()
|
||
else:
|
||
self.setup_v1()
|
||
|
||
def setup_v2(self):
|
||
# V2版本特有的初始化逻辑
|
||
pass
|
||
|
||
def setup_v1(self):
|
||
# V1版本特有的初始化逻辑
|
||
pass
|
||
```
|
||
|
||
## 2. 服务封装与使用示例
|
||
|
||
为了插件调用并共享实例,主程序针对几种服务进行了封装。以下是相关实现及如何在插件中使用这些封装的详细说明,帮助开发者快速将插件从 V1 升级到 V2。
|
||
|
||
### 2.1 服务封装类介绍
|
||
|
||
#### `ServiceInfo`
|
||
`ServiceInfo` 是一个数据类,用于封装服务的相关信息。
|
||
|
||
```python
|
||
from dataclasses import dataclass
|
||
from typing import Optional, Any
|
||
|
||
@dataclass
|
||
class ServiceInfo:
|
||
"""
|
||
封装服务相关信息的数据类
|
||
"""
|
||
# 名称
|
||
name: Optional[str] = None
|
||
# 实例
|
||
instance: Optional[Any] = None
|
||
# 模块
|
||
module: Optional[Any] = None
|
||
# 类型
|
||
type: Optional[str] = None
|
||
# 配置
|
||
config: Optional[Any] = None
|
||
```
|
||
|
||
#### `ServiceBaseHelper`
|
||
`ServiceBaseHelper` 是一个通用的服务帮助类,提供了获取配置和服务实例的通用逻辑。
|
||
|
||
```python
|
||
from typing import Dict, List, Optional, Type, TypeVar, Generic, Iterator
|
||
from app.core.module import ModuleManager
|
||
from app.helper.serviceconfig import ServiceConfigHelper
|
||
from app.schemas import ServiceInfo
|
||
from app.schemas.types import SystemConfigKey
|
||
|
||
TConf = TypeVar("TConf")
|
||
|
||
class ServiceBaseHelper(Generic[TConf]):

|
||
|
||
def get_configs(self, include_disabled: bool = False) -> Dict[str, TConf]:
|
||
"""
|
||
获取配置列表
|
||
"""
|
||
configs: List[TConf] = ServiceConfigHelper.get_configs(self.config_key, self.conf_type)
|
||
return {
|
||
config.name: config
|
||
for config in configs
|
||
if (config.name and config.type and config.enabled) or include_disabled
|
||
} if configs else {}
|
||
|
||
def get_config(self, name: str) -> Optional[TConf]:

|
||
|
||
def iterate_module_instances(self) -> Iterator[ServiceInfo]:
|
||
"""
|
||

|
||
"""
|
||
configs = self.get_configs()
|
||
for module_name in self.modules:
|
||
module = self.modulemanager.get_running_module(module_name)
|
||
if not module:
|
||
continue
|
||
module_instances = module.get_instances()
|
||
if not isinstance(module_instances, dict):
|
||

|
||

|
||

|
||

|
||

|
||

|
||
)
|
||
yield service_info
|
||
|
||
def get_services(self, type_filter: Optional[str] = None) -> Dict[str, ServiceInfo]:
|
||
"""
|
||

|
||
"""
|
||
return {
|
||
service_info.name: service_info
|
||
for service_info in self.iterate_module_instances()
|
||
if service_info.config and (type_filter is None or service_info.type == type_filter)
|
||
}
|
||
|
||
def get_service(self, name: str, type_filter: Optional[str] = None) -> Optional[ServiceInfo]:
|
||
"""
|
||

|
||
if not name:
|
||
return None
|
||
for service_info in self.iterate_module_instances():
|
||
if service_info.name == name:
|
||
if service_info.config and (type_filter is None or service_info.type == type_filter):
|
||
return service_info
|
||
return None
|
||
```
|
||
|
||
### 2.2 特定服务的帮助类
|
||
|
||
以下是针对不同服务类型的帮助类,这些类继承自 `ServiceBaseHelper`,并预设了特定的配置。同时,为了简化类型检查,新增了相应的方法来判断服务类型。
|
||
|
||
#### `DownloaderHelper`
|
||
用于管理下载器服务。
|
||
|
||
```python
|
||
from typing import Optional
|
||
|
||
from app.helper.servicebase import ServiceBaseHelper
|
||
from app.schemas import DownloaderConf, ServiceInfo
|
||
from app.schemas.types import SystemConfigKey
|
||
|
||
|
||
class DownloaderHelper(ServiceBaseHelper[DownloaderConf]):
|
||
"""
|
||
下载器帮助类
|
||
"""
|
||
|
||
def __init__(self, config: dict = None):
|
||
super().__init__(
|
||
config_key=SystemConfigKey.Downloaders,
|
||
conf_type=DownloaderConf,
|
||
modules=["QbittorrentModule", "TransmissionModule"]
|
||
)
|
||
|
||
def is_qbittorrent(self, service: Optional[ServiceInfo] = None, name: Optional[str] = None) -> bool:
|
||
"""
|
||
判断指定的下载器是否为 qbittorrent 类型,需要传入 `service` 或 `name` 中的任一参数
|
||
|
||
:param service: 要判断的服务信息
|
||
:param name: 服务的名称
|
||
:return: 如果服务类型为 qbittorrent,返回 True;否则返回 False。
|
||
"""
|
||
if not service:
|
||
service = self.get_service(name=name)
|
||
return service.type == "qbittorrent" if service else False
|
||
|
||
def is_transmission(self, service: Optional[ServiceInfo] = None, name: Optional[str] = None) -> bool:
|
||
"""
|
||

||
|
||

|
||
:return: 如果服务类型为 transmission,返回 True;否则返回 False。
|
||
"""
|
||
if not service:
|
||
service = self.get_service(name=name)
|
||
return service.type == "transmission" if service else False
|
||
```
|
||
|
||
#### `MediaServerHelper`
|
||
用于管理媒体服务器服务。
|
||
|
||
```python
|
||
from app.helper.servicebase import ServiceBaseHelper
|
||
from app.schemas import MediaServerConf
|
||
from app.schemas.types import SystemConfigKey
|
||
|
||
class MediaServerHelper(ServiceBaseHelper[MediaServerConf]):
|
||
"""
|
||
媒体服务器帮助类
|
||
"""
|
||
|
||
def __init__(self, config: dict = None):
|
||
super().__init__(
|
||
config_key=SystemConfigKey.MediaServers,
|
||
conf_type=MediaServerConf,
|
||
modules=["PlexModule", "EmbyModule", "JellyfinModule"]
|
||
)
|
||
|
||
...
|
||
```
|
||
|
||
#### `NotificationHelper`
|
||
用于管理消息通知服务。
|
||
|
||
```python
|
||
from app.helper.servicebase import ServiceBaseHelper
|
||
from app.schemas import NotificationConf
|
||
from app.schemas.types import SystemConfigKey
|
||
|
||
class NotificationHelper(ServiceBaseHelper[NotificationConf]):
|
||
"""
|
||
消息通知帮助类
|
||
"""
|
||
|
||
def __init__(self, config: dict = None):
|
||
super().__init__(
|
||
config_key=SystemConfigKey.Notifications,
|
||
conf_type=NotificationConf,
|
||
modules=["WechatModule", "WebPushModule", "VoceChatModule", "TelegramModule", "SynologyChatModule", "SlackModule"]
|
||
)
|
||
|
||
...
|
||
```
|
||
|
||
### 2.3 在插件中使用服务帮助类
|
||
|
||
通过这些帮助类,插件可以方便地获取和管理各种服务。以下是 `DownloaderHelper` 的使用示例,包括类型检查服务和监听模块重载事件的两种方法。
|
||
|
||
#### 获取下载器选项
|
||
|
||
插件可以通过 `DownloaderHelper` 获取所有可用的下载器配置,并生成选项列表供用户选择。
|
||
|
||
```python
|
||
from app.helper.downloader import DownloaderHelper
|
||
|
||
class MyPlugin:
|
||
def init_plugin(self, config: dict = None):
|
||
self.downloaderhelper = DownloaderHelper(config)
|
||
self.downloader_options = [
|
||
{"title": config.name, "value": config.name}
|
||
for config in self.downloaderhelper.get_configs().values()
|
||
]
|
||
```
|
||
|
||
#### 获取特定下载器服务
|
||
|
||
根据用户选择的下载器名称,插件可以获取对应的服务实例,并执行相应的操作。以下展示了两种方法:
|
||
|
||
1. **使用事件监听进行模块重载,从而保持服务实例共享**
|
||
|
||
如果外部模块进行了重载,需要监听模块重载事件以重置下载器服务。
|
||
|
||
```python
|
||
from typing import Optional, Union
|
||
from app.helper import DownloaderHelper
|
||
from app.modules.qbittorrent import Qbittorrent
|
||
from app.modules.transmission import Transmission
|
||
from app.events import EventType, eventmanager
|
||
|
||
class MyPlugin:
|
||
def init_plugin(self, config: dict = None):
|
||
self.downloaderhelper = DownloaderHelper(config)
|
||
self._downloader = None
|
||
self.__setup_downloader(config.get("downloader_name"))
|
||
|
||
def __setup_downloader(self, downloader_name: str):
|
||
self._downloader = self.downloaderhelper.get_service(name=downloader_name)
|
||
|
||
def __get_downloader(self) -> Optional[Union[Transmission, Qbittorrent]]:
|
||
"""
|
||
获取下载器实例
|
||
"""
|
||
if not self._downloader:
|
||
return None
|
||
return self._downloader.instance
|
||
|
||
@eventmanager.register(EventType.ModuleReload)
|
||
def module_reload(self, event: Event):
|
||
"""
|
||
模块重载事件
|
||
"""
|
||
if not event:
|
||
return
|
||
event_data = event.event_data or {}
|
||
module_id = event_data.get("module_id")
|
||
# 如果模块标识不存在,则说明所有模块均发生重载
|
||
if not module_id:
|
||
self.__setup_downloader()
|
||
|
||
def check_downloader_type(self) -> bool:
|
||
"""
|
||
检查下载器类型是否为 qbittorrent 或 transmission
|
||
"""
|
||
downloader = self.__get_downloader()
|
||
if self.downloaderhelper.is_qbittorrent(service=downloader):
|
||
# 处理 qbittorrent 类型
|
||
return True
|
||
elif self.downloaderhelper.is_transmission(service=downloader):
|
||
# 处理 transmission 类型
|
||
return True
|
||
return False
|
||
```
|
||
|
||
2. **使用 Property 实现服务实例共享**
|
||
|
||
通过 `Property` 方法,从而保持服务实例共享,而无需通过事件监听。
|
||
|
||
```python
|
||
from typing import Optional, Union
|
||
from app.helper import DownloaderHelper
|
||
from app.modules.qbittorrent import Qbittorrent
|
||
from app.modules.transmission import Transmission
|
||
|
||
class MyPlugin:
|
||
def init_plugin(self, config: dict = None):
|
||
self.downloaderhelper = DownloaderHelper(config)
|
||
|
||
@property
|
||
def service_info(self) -> Optional[ServiceInfo]:
|
||
"""
|
||
服务信息
|
||
"""
|
||
service = self.downloaderhelper.get_service(name=self.downloader_name)
|
||
if not service:
|
||
return None
|
||
|
||
if service.instance.is_inactive():
|
||
return None
|
||
|
||
return service
|
||
|
||
@property
|
||
def downloader(self) -> Optional[Union[Qbittorrent, Transmission]]:
|
||
"""
|
||
下载器实例
|
||
"""
|
||
return self.service_info.instance if self.service_info else None
|
||
|
||
def check_downloader_type(self) -> bool:
|
||
"""
|
||
检查下载器类型是否为 qbittorrent 或 transmission
|
||
"""
|
||
if self.downloaderhelper.is_qbittorrent(service=self.service_info):
|
||
# 处理 qbittorrent 类型
|
||
return True
|
||
elif self.downloaderhelper.is_transmission(service=self.service_info):
|
||
# 处理 transmission 类型
|
||
return True
|
||
return False
|
||
```
|
||
|
||
### 2.4 服务封装的优势
|
||
|
||
- **统一管理**:通过 `ServiceBaseHelper`,不同类型的服务配置和实例管理变得统一和简洁。
|
||
- **灵活扩展**:新增服务类型时,只需创建相应的帮助类,无需修改现有逻辑。
|
||
- **便捷调用**:插件可以轻松获取所需的服务实例,简化了服务的调用过程。
|
||
|
||
### 2.5 从 V1 升级到 V2 的注意事项
|
||
|
||
- **使用帮助类**:确保插件中使用了新的服务帮助类,如 `DownloaderHelper`、`MediaServerHelper`、`NotificationHelper` 等,而不是直接操作服务实例。
|
||
- **更新依赖**:检查并更新 `requirements.txt` 中的依赖,确保与 V2 的服务封装兼容。
|
||
- **测试插件**:在 V2 环境中全面测试插件,确保所有服务调用正常工作。 |
