javascript - mapDispatchToProps 速记导致流类型检查错误

Question

我想对 mapDispatchToProps 使用速记符号，但是当我替换老式的 bindActionCreators 策略时

function mapDispatchToProps(dispatch: Dispatch<any>): PropsFromDispatch {
  return {
    fetchStuff: () => dispatch(fetchStuffAction()),
  };
}
....
export default connect(mapStateToProps, mapDispatchToProps)(MyComponent);

使用 mapDispatchToProps 简写对象语法

const actions = {
  fetchStuff: fetchStuffAction,
};
...
export default connect(mapStateToProps, actions)(MyComponent);

我从流类型检查器那里收到以下投诉...

Cannot call connect because:
 • Either a callable signature is missing in object literal [1] but exists in MapDispatchToProps [2].
 • Or a callable signature is missing in object literal [1] but exists in MapDispatchToProps [3].

有什么想法吗？

Answer 1

mapDispatchToProps = (dispatch: Dispatch<*>) => ({
  fetchStuff: () => dispatch(fetchStuffAction())
})

你需要这样做。调度类型不是任何..
