reactjs - Redux 工具包和 createAsyncThunk 不适用于 axios 实例

Question

我有一个 react/typescript 项目。我正在使用 redux 来管理状态。

//store.ts
import { configureStore, combineReducers } from '@reduxjs/toolkit';
import { userReducer } from './user';

const RootReducer = combineReducers({
  user: userReducer
})

export const store = configureStore({
  reducer: RootReducer,
  devTools: true,
});

export type RootState = ReturnType<typeof store.getState>;
export type AppDispatch = typeof store.dispatch;

我还有一个 userSlice.ts 文件:

import { createAsyncThunk, createSlice } from '@reduxjs/toolkit';
import { signIn, signUp } from './../../services/api';
import type { UserCredential, UserInitialState } from './types';

const initialState: UserInitialState = {
  accessToken: null,
  status: 'init',
  user: {
    id: '',
    email: '',
    firstName: null,
    lastName: null,
    isAuthorized: false,
    imported: false,

    teamId: '',
    role: '',
    linkedinLink: null,
    isReceivingNotifications: false,
    avatarKey: null,
    loggedInAt: '',
    createdAt: '',
    updatedAt: '',
    deletedAt: null,
  },
};

const signUpRequest = createAsyncThunk('user/signUpRequest', async (data: UserCredential) => {
  const response = await signUp(data);
  return response.data;
});

const signInRequest = createAsyncThunk('user/signInRequest', async (data: UserCredential) => {
  const response = await signIn(data);
  return response.data;
});

const userSlice = createSlice({
  name: 'user',
  initialState,
  reducers: {
    logOut() {
      return initialState;
    },
  },
  extraReducers: (builder) => {
    builder.addCase(signInRequest.pending, (state, action) => {
      state.status = 'pending';
    });
    builder.addCase(signInRequest.fulfilled, (state, action) => {
      const { user, accessToken } = action.payload;
      return { accessToken, ...user };
    });
  },
});

export const userSliceActions = {...userSlice.actions};
export default userSlice.reducer;

在这个切片中，我使用了 API 中的两个函数(signIn、signUp)

这些函数在下一个文件中描述:

//api.ts
import { UserCredential } from '../store/user/types';
import { AxiosPromise } from 'axios';
import ApiClient from './ApiClient';

export const signUp = (data: UserCredential): AxiosPromise => {
  return ApiClient.post('v1/auth/sign_up', { data });
};

export const signIn = (data: UserCredential): AxiosPromise => {
  return ApiClient.post('v1/auth/sign_in', { data });
};

上面我使用了来自 ApiClient.ts 文件的简单 axios 实例

import axios, { AxiosInstance, AxiosRequestConfig } from 'axios';
import { store } from '../store/store';
const baseUrl = 'https://************/api';// valid url

class ApiClient {
  private api: AxiosInstance;

  constructor() {
    this.api = axios.create({
      baseURL: baseUrl,
      headers: {
        'Content-Type': 'application/json',
      },
    });

    this.api.interceptors.request.use((config) => {
      const token = store.getState().user.accessToken;
      if (token !== null) {
        config.headers.Authorization = `Bearer ${token}`;
      }
      return config;
    });
  }

  post(url: string, { data }: AxiosRequestConfig) {
    return this.api.post(url, data);
  }

  get(url: string) {
    return this.api.get(url);
  }

  put(url: string, { data }: AxiosRequestConfig) {
    return this.api.put(url, data);
  }

  delete(url: string) {
    return this.api.delete(url);
  }
}

export default new ApiClient();

值得注意的是，我尝试获取 token ，如果它存在，则在每次请求时将其写入 header 。

因此，我的商店没有初始化(它是空的)。在控制台中我有错误:

1. 没有为关键“用户”提供reducer
2. 商店没有有效的 reducer 。确保传递给 combineReducers 的参数是一个值为 reducers 的对象。

注意 1:如果我删除 userSlice.ts 中的 API 调用，错误就会消失并且商店可以正常工作。在这种形式下，一切都开始了，但我需要在 userSlice 中调用 API...

import { createAsyncThunk, createSlice } from '@reduxjs/toolkit';
import type { UserCredential, UserInitialState } from './types';

const initialState: UserInitialState = {
  accessToken: null,
  status: 'init',
  user: {
    id: '',
    email: '',
    firstName: null,
    lastName: null,
    isAuthorized: false,
    imported: false,
    teamId: '',
    role: '',
    linkedinLink: null,
    isReceivingNotifications: false,
    avatarKey: null,
    loggedInAt: '',
    createdAt: '',
    updatedAt: '',
    deletedAt: null,
  },
};

const userSlice = createSlice({
  name: 'user',
  initialState,
  reducers: {
    logOut() {
      return initialState;
    },
  },
});

export const userSliceActions = { ...userSlice.actions };
export default userSlice.reducer;

我傻了! Redux 文档不建议在非组件文件中导入存储。我引用 “您应该避免将商店直接导入到其他代码库文件中。虽然它在某些情况下可能有效，但通常最终会导致循环导入依赖性错误。”这是我的情况，我将商店导入到 ApiClient.ts 文件，哇哦。按照文档，我使用了 injectStore 函数。我分享链接 https://redux.js.org/faq/code-structure#how-can-i-use-the-redux-store-in-non-component-files
