Redux 工具包从 thunk 访问状态

Question

我想在 thunk 中获取存储在状态中的值，在本例中为projectId。我可以在调用操作时访问该值而不将其作为参数传递吗？

interface RepoDetailsState {
      openIssuesCount: number
      error: string | null
    }

const initialState: RepoDetailsState = {
  openIssuesCount: -1,
  error: null,
  projectId: 'someProjectId'

}

const repoDetails = createSlice({
  name: 'repoDetails',
  initialState,
  reducers: {
  // ... reducers ...
  }
})

export const {
  getRepoDetailsSuccess,
  getRepoDetailsFailed
} = repoDetails.actions

export default repoDetails.reducer

export const fetchIssuesCount = (
  org: string,
  repo: string
): AppThunk => async dispatch => {
 //How do I access projectId from state?
}

您可以通过getState参数访问您的状态。

export const fetchIssuesCount = (
  org: string,
  repo: string
): AppThunk => async (dispatch, getState) => {
// Do something with state
 getState()
}
