警告：setState(…):在Redux/Immutable的现有状态转换期间无法更新

Question

const mapStateToProps = (state) => {
  return {
    notifications: state.get("notifications").get("notifications").toJS()
  }
}

import {connect} from "react-redux"
import {removeNotification, deactivateNotification} from "./actions"
import Notifications from "./Notifications.jsx"

const mapStateToProps = (state) => {
  return {
    notifications: state.get("notifications").get("notifications").toJS()
  }
}

const mapDispatchToProps = (dispatch) => {
  return {
    closeNotification: (notification) => {
      dispatch(deactivateNotification(notification.id))
      setTimeout(() => dispatch(removeNotification(notification.id)), 2000)
    }
  }
}

const NotificationsBotBot = connect(mapStateToProps, mapDispatchToProps)(Notifications)
export default NotificationsBotBot

import React from "react"

class Notifications extends React.Component {
  render() {
    return (
      <div></div>
    )
  }
}

export default Notifications

在进一步的调试中，我发现，以上可能不是根本原因，毕竟，我可以保留通知，但我需要删除dispatch（push（“/domains”）)我的重定向。

export function doLogin (username, password) {
  return function (dispatch) {
    dispatch(loginRequest())
    console.log("Simulated login with", username, password)
    setTimeout(() => {
      dispatch(loginSuccess(`PLACEHOLDER_TOKEN${Date.now()}`))
      dispatch(addNotification({
        children: "Successfully logged in",
        type: "accept",
        timeout: 2000,
        action: "Ok"
      }))
      dispatch(push("/domains"))
    }, 1000)
  }
}

import {connect} from "react-redux"
import DomainsIndex from "./DomainsIndex.jsx"

export default connect()(DomainsIndex)

export default class DomainsIndex extends React.Component {
  render() {
    return (
      <div>
        <h1>Domains</h1>
      </div>
    )
  }
}

  <Provider store={store}>
    <ConnectedRouter history={history}>
      <Layout>
        <Panel>
          <Switch>
            <Route path="/auth" />
            <Route component={TopBar} />
          </Switch>

          <Switch>
            <Route exact path="/" component={Index} />
            <Route path="/auth/login" component={LoginBotBot} />
            <AuthenticatedRoute exact path="/domains" component={DomainsPage} />
            <AuthenticatedRoute exact path="/domain/:id" component={DomainPage} />
            <Route component={Http404} />
          </Switch>
          <Notifications />
        </Panel>
      </Layout>
    </ConnectedRouter>
  </Provider>

Answer 1

setTimeout(() => dispatch(push('/domains')), 0)
