createAsyncThunk创建的action无法使用dispatch

[hikzhang]

相关平台

微信小程序

小程序基础库: 3.4.1 使用框架: React

复现步骤

1. 在slice中定义foo = createAsyncThunk(...)，并在createSlice的extrareducers中使用build.addCase(foo.pending...)等
2. 在页面中使用dispatch(foo)

期望结果

foo定义的async functionf

实际结果

执行时报错：AbortController is not defined

ReferenceError: AbortController is not defined

补充信息

实际taro版本是3.6.26（无可选项）

解决方法： 1，安装这俩包：yet-another-abortcontroller-polyfill，event-target-polyfill 2，app.js import： import 'event-target-polyfill'; import 'yet-another-abortcontroller-polyfill';

[hikzhang]

感谢！按你的解决方法成功运行了。

不过是否应该从Taro框架本身引入才更好呢。

[hikzhang]

我按照seekerliu https://github.com/seekerliu 提供的解决方案已经可以正常使用了。

@hikzhang 我遇到的问题是，模拟器正常，真机调试dispatch之后action没有执行。我的是抖音小程序。

装了以后直接白屏了

重新启动看看呢？似乎有些编译缓存不会被更新到。

我这边解决了，后面遇到的同学可以参考，微信小程序应该是可以通过上述的polyfill方案解决 抖音小程序因为限制了globalThis和window的访问，pollyfill不行，引入那两个包以后会白屏，通过分析可以知道这个报错的主要原因是createAsyncThunk里面维护的promise abort状态导致的，可以通过绕过createAsyncThunk来解决，比如：

1. 手动维护请求的状态
2. 或者用redux-thunk之类的库去维护异步请求状态就可以避免了 参考：

import { createSlice } from '@reduxjs/toolkit';
import axios from 'axios';

const initialState = {
  data: null,
  loading: false,
  error: null,
  // 添加一个额外的字段
  userId: null, // 假设我们需要使用这个字段来决定是否请求数据
};

const mySlice = createSlice({
  name: 'mySlice',
  initialState,
  reducers: {
    fetchStart: (state) => {
      state.loading = true;
      state.error = null;
    },
    fetchSuccess: (state, action) => {
      state.loading = false;
      state.data = action.payload;
    },
    fetchError: (state, action) => {
      state.loading = false;
      state.error = action.payload;
    },
    setUserId: (state, action) => {
      state.userId = action.payload;
    },
  },
});

export const { fetchStart, fetchSuccess, fetchError, setUserId } = mySlice.actions;

// 修改后的 fetchData，读取 state
export const fetchData = () => async (dispatch, getState) => {
  const state = getState(); // 读取当前 state
  const { userId } = state.mySlice; // 从 state 中获取 userId
  
  // 如果 userId 不存在或无效，则不进行请求
  if (!userId) {
    console.warn('User ID is required for this request');
    return;
  }

  dispatch(fetchStart()); // 请求开始，设置 loading 为 true
  try {
    const response = await axios.get(`https://api.example.com/data/${userId}`); // 使用 state 中的 userId
    dispatch(fetchSuccess(response.data)); // 请求成功，设置 data 和 loading 状态
  } catch (error) {
    dispatch(fetchError(error.toString())); // 请求失败，设置 error 和 loading 状态
  }
};

export default mySlice.reducer;

现在好多库都有依赖AbortController 上面的方法尝试过无效，官方有什么更好的方案吗？
