【问题描述】：

我正在尝试在我的 React 应用程序中实现 redux 工具包，但出现上述错误。我还没有派出任何行动，因为我只是在检查我的网站是否加载。

subredditSlice.js

import { createAsyncThunk, createSlice } from "@reduxjs/toolkit";
import axios from "axios";
export const getSubredditData = createAsyncThunk(
  "asyncRedux/subredditData",
  async () => {
    const result = await axios.get("http://127.0.0.1:500/subreddit_comments");
    return result;
  }
);

const subredditSlice = createSlice({
  name: "subredditSlice",
  initialState: {
    data: {},
    status: "idle",
    authError: null,
  },
  reducers: {},
  extraReducers(builder) {
    builder
      .addCase(getSubredditData.pending, (state, action) => {
        state.status = "loading";
      })
      .addCase(getSubredditData.fulfilled, (state, action) => {
        state.status = "succeeded";
        // Add any fetched posts to the array
        state.data = action.payload;
      })
      .addCase(getSubredditData.rejected, (state, action) => {
        state.status = "failed";
        state.error = action.error.message;
      });
  },
});

export default subredditSlice.reducer;

商店.js

import { configureStore } from "@reduxjs/toolkit";
import subredditReducer from "./Pages/Subreddit/subredditSlice";
export default configureStore({
  reducer: {
    subreddit: subredditReducer,
  },
});

索引.js

import React from "react";
import ReactDOM from "react-dom/client";
import "./index.css";
import { RouterProvider } from "react-router-dom";
import store from "./store";
import { Provider } from "react-redux";
import App from "./App";

const root = ReactDOM.createRoot(document.getElementById("root"));
root.render(
  <>
    <Provider store={store} />
    <App />
    <Provider />
  </>
);

该网站甚至没有加载，当我删除提供者标签时它工作正常，所以我得出结论，错误出在上述三个文件中的某个地方。我使用了完全相同的 redux 工具包格式，但不确定为什么现在失败了。

在subreddit切片在最后一种情况下，您是在尝试修改 state.error 还是打字错误？因为该州不存在该财产

昨天，我构建了这个基本的应用程序来理解 Redux 的概念。希望这会对你有所帮助。 https://github.com/nirmalsinghoo7/Basic-Redux-react
