嗨，我有一个组件将Redux集成到我的react应用程序中。我先讲第二部分，然后讲第三部分。我不希望将我在第一个组件中获得的数据传递给第二个，然后在道具中传递给第三个。

我想使用redux存储来做到这一点。有什么办法吗？

App.js

import React, { Component } from "react";
import logo from "./logo.svg";
import "./App.css";
import RoundedButton from "./RoundedButton";
import { connect } from "react-redux";
import { bindActionCreators } from "redux";
import * as actions from "./actions/index";

class App extends Component {
  constructor(props) {
    super(props);
    this.state = {
      score: 0,
      status: "",
      userSelected: "",
      computerSelected: "",
      visibility: [true, true, true],
      buttonVisibility: false
    };
    this.clickitem = this.clickitem.bind(this);
    this.handlePlayAgain = this.handlePlayAgain.bind(this);
  }

  handlePlayAgain() {
    this.setState({
      buttonVisibility: false,
      visibility: [true, true, true]
    });
  }

  clickitem(user) {
    var url = "http://localhost:4000/generate-random";
    this.setState({ userSelected: user });

    fetch(url)
      .then(response => {
        if (response.status >= 400) {
          throw new Error("Bad response from server");
        }
        return response.json();
      })
      .then(data => {
        var computer = data.item;
        this.setState({ computerSelected: computer });
        if (
          (user === "Rock" && computer === "Scissors") ||
          (user === "Paper" && computer === "Rock") ||
          (user === "Scissors" && computer === "Paper")
        ) {
          this.props.increment();
        } else if (user === computer) {
          this.props.doNothing();
        } else {
          this.props.decrement();
        }

        console.log(user + " " + computer);
        console.log("------------------------------------");

        App.contextTypes = { store: React.PropTypes.object };
        let store = this.context.store;
        console.log(store);

        arrayvar = [];

        var arrayvar = [];
        if (user === "Rock" && computer === "Rock") {
          arrayvar = [true, false, false];
        } else if (user === "Paper" && computer === "Paper") {
          arrayvar = [false, true, false];
        } else if (user === "Scissors" && computer === "Scissors") {
          arrayvar = [false, false, true];
        } else if (
          (user === "Rock" && computer === "Paper") ||
          (user === "Paper" && computer === "Rock")
        ) {
          arrayvar = [true, true, false];
        } else if (
          (user === "Rock" && computer === "Scissors") ||
          (user === "Scissors" || computer === "Rock")
        ) {
          arrayvar = [true, false, true];
        } else if (
          (user === "Paper" && computer === "Scissors") ||
          (user === "Scissors" || computer === "Paper")
        ) {
          arrayvar = [false, true, true];
        }
        this.setState({ visibility: arrayvar });
        this.setState({
          buttonVisibility: true
        });
      });
  }

  render() {
    return (
      <div className="CenterDiv">
        <div className="AppTitle">
          <b>Score: {this.props.score}</b>
          <div>
            {this.state.visibility[0]
              ? <RoundedButton
                  text="Rock"
                  clickitem={this.clickitem}

                          : ""
                  }
                />
              : null}
            {this.state.visibility[1]
              ? <RoundedButton
                  text="Paper"
                  clickitem={this.clickitem}
                  label={
                    this.state.userSelected === "Paper" &&
                      this.state.computerSelected === "Paper"
                      ? "User & Computer Selected"
                      : this.state.userSelected == "Paper"
                        ? "User Selected"
                        : this.state.computerSelected === "Paper"
                          ? "Computer Selected"
                          : ""
                  }
                />
              : null}
            {this.state.visibility[2]
              ? <RoundedButton

                  clickitem={this.clickitem}
                  label={

                      this.state.computerSelected === "Scissors"
                      ? "User & Computer Selected"
                      : this.state.userSelected === "Scissors"
                        ? "User Selected"
                        : this.state.computerSelected === "Scissors"
                          ? "Computer Selected"
                          : ""
                  }
                />
              : null}
          </div>

          <div className="Status">{this.props.status}</div>

          {this.state.buttonVisibility
            ? <button onClick={this.handlePlayAgain} style={{ margin: 30 }}>
                Play Again
              </button>
            : null}

        </div>
      </div>
    );
  }
}

function mapStateToProps(state) {
  return { score: state.score, status: state.status };
}

export default connect(mapStateToProps, actions)(App);

index.js

import React from "react";
import ReactDOM from "react-dom";
import App from "./App";
import registerServiceWorker from "./registerServiceWorker";
import "./index.css";

import { Provider } from "react-redux";
import { createStore } from "redux";
import scoreReducer from "./reducers";

let store = createStore(scoreReducer);

ReactDOM.render(
  <Provider store={store}><App /></Provider>,
  document.getElementById("root")
);
registerServiceWorker();

secondcomponent.js

export default class SecondComponent extends Component {
  render() {
    return (
       // print score which is in redux
    );
  }
}

第三component.js

export default class ThirdComponent extends Component {
  render() {
    return (
       // print score which is in redux
    );
  }
}

在多个组件中访问redux存储的方式是什么？
