[英]Redux-Saga call not working
我正在尝试使用redux-saga的call
函数,但未call
该函数:
以下是我的saga.js:
import { takeLatest, put, call } from 'redux-saga/effects';
import {NavigationActions} from 'react-navigation';
import NavigatorService from '../services/navigator';
import { SIGN_UP, AUTHENTICATION_FAILED, SIGN_UP_SUCCESS, LOGIN, LOGIN_SUCCESS} from '../actions/index';
import firebase from 'firebase';
function* signUp(action){
try{
const auth = firebase.auth();
const result = yield call([
auth, auth.createUserWithEmailAndPassword],
action.user.email,
action.user.password
);
console.log("signup success") // this is being logged
call([
NavigatorService, NavigatorService.navigate],
'Tabs'
); // not being called
yield put({type: SIGN_UP_SUCCESS, user: action.user});
console.log("done") // not being logged
}
catch(error){
const error_message = {code: error.code, message: error.message};
console.log(error_message);
yield put({type: AUTHENTICATION_FAILED, error: error_message});
}
}
function* rootSaga(){
yield takeLatest(SIGN_UP, signUp);
}
export default rootSaga;
我尝试从其他组件调用NavigatorService.navigate
,并且工作正常。 在这种情况下,我什至没有登录NavigatorService
。 谁能告诉我我做错了吗?
您错过了一个yield
。 它应该是:
yield call([ NavigatorService, NavigatorService.navigate ], 'Tabs');
