# nonebot.dependencies
|
||
|
|
|
||
|

|
|
|
||
|
|
- **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**
|
||
|
|

|
||
|
|
|
||
|
|
## _class_ `Dependent(*, call, pre_checkers=None, params=None, parameterless=None, allow_types=None)` {#Dependent}
|
||
|
|
|
||
|
|
- **说明**
|
||
|
|
|
||
|
|
依赖注入容器
|

|
|
|
||
|
|
- **参数**

|
||
|
|

|
||
|
|
|
||
|
