javascript – Redux-Saga的Firebase身份验证无效

我正在尝试使用firebase auth创建一个新用户.我正在使用redux-saga进行上述调用.

下面是我的saga.js：

import { takeLatest, put } from 'redux-saga/effects';
import { SIGN_UP, AUTHENTICATION_FAILED, SIGN_UP_SUCCESS} from '../actions/index';
import firebase from 'firebase';


function* signUp(action){
    console.log("about to call authentication"); // This being printed
    firebase.auth().createUserWithEmailAndPassword(action.user.email, action.user.password)
            .then(function*(result){
                    console.log("success"); // Not being loged
                    yield put({SIGN_UP_SUCCESS, user: action.user});
            }).catch(function*(error){
                    console.log("failed"); //Not being loged
                    let error_message = { code: error.code, message: error.message};
                    yield put({AUTHENTICATION_FAILED, error: error_message});
            });
}

function* rootSaga(){
  yield takeLatest(SIGN_UP, signUp);
}

export  default rootSaga;

然后内部的代码和catch没有被执行,正在调用注册生成器函数.谁能告诉我我做错了什么？

解决方法:

编写代码的更多redux-saga惯用方法如下所示：

function* signUp(action){
  try {
    const auth = firebase.auth()
    const result = yield call(
      [auth, auth.createUserWithEmailAndPassword],
      action.user.email,
      action.user.password
    )

    yield put({ type: SIGN_UP_SUCCESS, user: action.user });
  } catch (error) {
    const error_message = { code: error.code, message: error.message };

    yield put({ type: AUTHENTICATION_FAILED, error: error_message });
  }
}
