使用 Redux-thunk 进行异步/等待。出现错误：操作必须是普通对象。使用自定义中间件进行异步操作

Question

我正在尝试将 async await 与 redux-thunk 中间件一起使用，但出现红屏并显示错误 Actions must be plain objects。使用自定义中间件进行异步操作。我想我没有返回正确的值类型。我按下一个按钮将 twitter 用户链接到现有的 firebase 帐户。该按钮到达一个名为 toggleTwitterAuthState 的函数：

export const toggleTwitterAuthState =  (twitterIsCurrentlyLinked, contributorUserId) => {

  let actionName = "";


    if (twitterIsCurrentlyLinked) {
      console.log("Unlinking twitter");
      actionName = "TWITTER_UNLINK";
       unlinkTwitterAccount(contributorUserId);
    } else {
      console.log("Linking twitter");
      linkTwitterAccount(contributorUserId);
      actionName = "TWITTER_LINK";
    }



};

它调用函数linkTwitterAccount，我正在使用react-native-debugger在返回异步（调度）上放置一个断点并到达那里，但是里面的代码永远不会被执行，我得到那个带有错误的红屏如上所述

linkTwitterAccount =  (contributorUserId) => {

       return async (dispatch)=>{

        console.log("about to link twitter user");
        RNTwitterSignIn.init(config.twitter.consumer_key, config.twitter.consumer_secret);
        dispatch(authOperationBegan());

        let linkToTwitterResult;
        let twitterTokensObject;
        let loginData;
        //get credentials

        try {
          loginData = await RNTwitterSignIn.logIn();
          console.log("Twitter login data", loginData);
        } catch (err) {
          console.log("Error with twitter login result", error);
          dispatch(authOperationFailed(err));
        }

        //link to react native firebase

        try {

          const {
            authToken,
            authTokenSecret
          } = loginData;
          const user = firebase.auth().currentUser;
          // create a new firebase credential with the token
          const twitterCredential = firebase.auth.TwitterAuthProvider.credential(authToken, authTokenSecret);
          console.log(twitterCredential);

          // link to this account with credential
          const linkingResult = await user.linkAndRetrieveDataWithCredential(twitterCredential);
          console.log("Success Linking twitter", linkingResult);

          var currentUser = linkingResult.user;

          var displayName;
          var photoUrl;
          var email;
          var phoneNumber;
          var twitterUserId;

          currentUser.providerData.map(elem => {
            if (elem.providerId == "twitter.com") {

              displayName = elem.displayName;
              photoUrl = elem.photoURL;
              email = elem.email;
              phoneNumber = elem.phoneNumber;
              twitterUserId = elem.uid;

            }
          });


          twitterTokensObject = {
            "contributor_user_id": contributorUserId,
            "twitter_id": twitterUserId,
            "twitter_access_token": authToken,
            "twitter_access_token_secret": authTokenSecret,
            "display_name": displayName,
            "photo_url": photoUrl,
            "phone_number": phoneNumber,
            "email": email
          };


        } catch (err) {
          alert("Error linking asociando cuenta: " + err);
          dispatch(authOperationFailed(err));
        }

        //TODO: upsert twitter user data to DB

        dispatch(authOperationFinished());
       }
      }

我的 redux thunk 配置是这样的，我是从 udemy 课程中学到的，那家伙使用了一个 componse 函数 https://www.udemy.com/react-native-the-practical-guide/ ：

import { createStore, combineReducers, compose, applyMiddleware } from 'redux';
import thunk from "redux-thunk";

import foundationsReducer from './reducers/foundations';
import sponsorsReducer from './reducers/sponsors';
import authReducer from './reducers/auth';

const rootReducer = combineReducers({
    foundations: foundationsReducer,
    sponsors: sponsorsReducer,
    auth:authReducer
});

let composeEnhancers = compose;

if (__DEV__) {
    composeEnhancers = window.__REDUX_DEVTOOLS_EXTENSION_COMPOSE__ || compose;
}

const configureStore = () => {
    return createStore(rootReducer, composeEnhancers(applyMiddleware(thunk)));
};

export default configureStore;

我在我的 index.js 上使用这个 redux thunk 配置：

import React from 'react';
import { AppRegistry } from 'react-native';
import { Provider } from 'react-redux';
import App from './App';
import configureStore from './src/store/configureStore';

const store = configureStore();

const RNRedux = () => (
    <Provider store={store}>
        <App />
    </Provider>
);

AppRegistry.registerComponent('rnfundkers', () => RNRedux);

只是为了让您知道，redux thunk 正在为其他操作工作，但是这种异步等待情况在我看不到的方式上有所不同。知道可能出了什么问题吗？如果我摆脱了包装器和调度，函数本身就可以工作，它会做它必须做的事情，但是因为我需要这些调度来更新微调器，所以就出现了这个问题。谢谢！！

编辑：以下是操作：

export const authOperationBegan =  () => {
  return {
    type: AUTH_OPERATION_BEGAN
  };
}

export const authOperationFinished =  () => {
  return {
    type: AUTH_OPERATION_FINISHED
  };
}

export const authOperationFailed =  (err) => {
  return {
    type: AUTH_OPERATION_FAILED,
    error: err
  };
}

我还有其他功能可以发送相同的 3 个操作，并且它们工作正常，例如这个：

export const tryAuth = (authData, authMode) => {
  return dispatch => {
    dispatch(authOperationBegan());

    const email = authData.email,
      password = authData.password;

    if (authMode === "signup") {

      firebase.auth().createUserWithEmailAndPassword(email, password)
        .then((user) => {


          // TODO: upsert user to our db
          dispatch(authOperationFinished());

        })
        .catch((error) => {
          const {
            code,
            message
          } = error;

          dispatch(authOperationFailed(err));

        });

    } else if (authMode == "login") {

      firebase.auth().signInAndRetrieveDataWithEmailAndPassword(email, password)
        .then((data) => {

          dispatch(authOperationFinished());

        })
        .catch((error) => {
          const {
            code,
            message
          } = error;
          console.log("error", message);

          dispatch(authOperationFailed(err));

        });

    }

  };
};

你必须发送你的 thunk

export const toggleTwitterAuthState =  (twitterIsCurrentlyLinked, contributorUserId) => dispatch => {
  let actionName = "";
  if (twitterIsCurrentlyLinked) {
    console.log("Unlinking twitter");
    actionName = "TWITTER_UNLINK";
    unlinkTwitterAccount(contributorUserId);
  } else {
    console.log("Linking twitter");
    dispatch(linkTwitterAccount(contributorUserId));
    actionName = "TWITTER_LINK";
  }
};
