# 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`
- `validate` (bool)
- `**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}
- **参数**
- `call` (\_DependentCallable[R])
- `allow_types` (tuple[type[Param], ...])
- **返回**
- tuple[[ModelField](../compat.md#ModelField), ...]
### _staticmethod_ `parse_parameterless(parameterless, allow_types)` {#Dependent-parse-parameterless}
- **参数**
- `parameterless` (tuple[Any, ...])
- `allow_types` (tuple[type[Param], ...])
- **返回**
- tuple[Param, ...]
### _classmethod_ `parse(*, call, parameterless=None, allow_types)` {#Dependent-parse}
- **参数**
- `call` (\_DependentCallable[R])
- `parameterless` (Iterable[Any] | None)
- `allow_types` (Iterable[type[Param]])
- **返回**
- Dependent[R]
### _async method_ `check(**params)` {#Dependent-check}
- **参数**
- `**params` (Any)
- **返回**
- None
### _async method_ `solve(**params)` {#Dependent-solve}
- **参数**
- `**params` (Any)
- **返回**
- dict[str, Any]
