我可以使用 redux 工具包访问 createAsyncThunk w/axios 中的状态吗？

Question

我对 redux 工具包还很陌生，所以我仍然遇到一些问题！

根据下面的代码，我正在尝试访问我的 createAsyncThunk 中的状态（loginDetails.username 和 loginDetails.password）。我显然在这里做错了什么——我尝试在另一个文件中编写 createAsyncThunk 函数，尝试访问该文件中的状态，然后导入该函数，但无论哪种方式都失败了。

// Import: Packages
import { createSlice, createAsyncThunk } from "@reduxjs/toolkit";
import axios from "axios";

// AsyncThunk: getUserDetails
export const getUserDetails = createAsyncThunk(
  "userDetails/getUserDetails",
  async () => {
    try {
      const apiUrl = process.env.REACT_APP_URL;

      var config = {
        method: "get",
        url: `${apiUrl}/claimSet?UserName=${state.loginDetails.username}&Password=${state.loginDetails.password}`,
        headers: {
          accept: "application/json",
        },
      };

      const response = await axios(config);
      const data = await response.data;
      return data;
    } catch (error) {
      console.log(error);
    }
  }
);

// Slice: userDetailsSlice
export const userDetailsSlice = createSlice({
  name: "userDetails",
  initialState: {
    loginDetails: {
      username: "",
      password: "",
    },
    details: [],
    status: null,
  },
  reducers: {
    addUsername: (state, { payload }) => {
      state.loginDetails.username = payload;
    },
    addPassword: (state, { payload }) => {
      state.loginDetails.password = payload;
    },
  },
  extraReducers: {
    [getUserDetails.pending]: (state, action) => {
      state.status = "loading";
    },
    [getUserDetails.fulfilled]: (state, { payload }) => {
      state.details = payload;
      state.status = "success";
    },
    [getUserDetails.rejected]: (state, action) => {
      state.status = "failed";
    },
  },
});

// Actions: addUsername, addPassword
export const { addUsername, addPassword } = userDetailsSlice.actions;

// Reducer: userDetailsSlice.reducer
export default userDetailsSlice.reducer;

配置中的代码 url ${state.loginDetails.username} 等只是获取状态的许多失败尝试之一。我知道问题的一部分是 createAsyncThunk 在下面的 state/slide 之前声明，但我似乎仍然找不到解决它的方法。

任何帮助将不胜感激！

异步函数使用“payload”参数，其次使用包含 getState 方法的 thunkAPI 对象。

payloadCreator

thunkAPI: an object containing all of the parameters that are normally passed to a Redux thunk function, as well as additional options:

dispatch: the Redux store dispatch method

getState: the Redux store getState method

extra: the "extra argument" given to the thunk middleware on setup, if available

requestId: a unique string ID value that was automatically generated to identify this request sequence

signal: an AbortController.signal object that may be used to see if another part of the app logic has marked this request as needing cancelation.

rejectWithValue: rejectWithValue is a utility function that you can return in your action creator to return a rejected response with a defined payload. It will pass whatever value you give it and return it in the payload of the rejected action.

// AsyncThunk: getUserDetails
export const getUserDetails = createAsyncThunk(
  "userDetails/getUserDetails",
  async (arg, { getState }) => { // <-- destructure getState method
    const state = getState(); // <-- invoke and access state object
    try {
      const apiUrl = process.env.REACT_APP_URL;

      var config = {
        method: "get",
        url: `${apiUrl}/claimSet?UserName=${state.loginDetails.username}&Password=${state.loginDetails.password}`,
        headers: {
          accept: "application/json",
        },
      };

      const response = await axios(config);
      const data = await response.data;
      return data;
    } catch (error) {
      console.log(error);
    }
  }
);

Can I access state inside a createAsyncThunk w/axios with redux toolkit?

reactjs

redux
