# nonebot.dependencies
|
||
|
|
|
||
|
|
本模块模块实现了依赖注入的定义与处理。
|
||
|
|
|
||
|
|
## _abstract class_ `Param(*args, validate=False, **kwargs)` {#Param}
|
||
|
|
|
||
|
|
- **说明**
|
||
|
|
|
||
|
|
依赖注入的基本单元 —— 参数。
|
||
|
|
|
||
|
|
继承自 `pydantic.fields.FieldInfo`，用于描述参数信息（不包括参数名）。
|
||
|
|
|
||
|
|
- **参数**
|
||
|
|
|
||
|
|
- `*args`
|
||
|
|
|
||
|
|

|
||
|
|
|
||
|
|
- `**kwargs` (Any)
|
||
|
|
|
||
|
|
## _class_ `Dependent(<auto>)` {#Dependent}
|
||
|
|
|
||
|
|
- **说明:** 依赖注入容器
|
||
|
|
|
||
|
|
- **参数**
|

|
|
|
||
|
|
- `call`: 依赖注入的可调用对象，可以是任何 Callable 对象
|
||
|
|
|
||
|
|
- `pre_checkers`: 依赖注入解析前的参数检查
|
||
|
|
|
||
|
|
- `params`: 具名参数列表
|
||
|
|
|
||
|
|
- `parameterless`: 匿名参数列表
|
||
|
|
|
||
|
|
- `allow_types`: 允许的参数类型
|
||
|
|
|
||
|
|
### _staticmethod_ `parse_params(call, allow_types)` {#Dependent-parse-params}
