Question

我正在尝试在私人路线中传递几个道具。写这个的正确方法是什么，我错过了什么？这是我的代码。我的应用程序使用此代码，因为用户能够登录并查看仪表板。然而，道具没有通过。有没有办法将 props 传递给私有路由？

   <PrivateRoute exact path="/dashboard" component={Dashboard} render={routeProps =>
            <Dashboard
            handleUpdate={this.handleUpdate}
            book={this.state.book}
            info={this.state.info}
            {...routeProps} />}
          />

仪表板组件

class Dashboard extends Component {

    state = {
        book: this.props.book,
        info: this.props.info, 
        error: '',
    }

    onLogoutClick = e => {
        e.preventDefault();
        this.props.logoutUser();
    };

    render() {
    
    console.log(`BOOK STATE IN DB: ${this.state.book}`)
        
    const { user } = this.props.auth;
    return(
            <div>
                <h4>
                    <b>This is your page</b> {user.name}
                </h4>
                <button onClick={this.onLogoutClick}>Logout</button>
                <h2>Search Book</h2>
                <Search 
                    handleUpdate={this.props.handleUpdate}
                />
                <h4>Book Results</h4>
                <div>{this.state.book}</div>
            </div>
        );
    }
}

Dashboard.propTypes = {
    logoutUser: PropTypes.func.isRequired,
    auth: PropTypes.object.isRequired
};

const mapStateToProps = state => ({
    auth: state.auth
});

export default connect(
    mapStateToProps,
    { logoutUser }
)(Dashboard);

私人路线

import React from "react";
import { Route, Redirect } from "react-router-dom";
import { connect } from "react-redux";
import PropTypes from "prop-types";

const PrivateRoute = ({ component: Component, auth, ...rest }) => (
  console.log(auth),

  <Route
  {...rest}
  render={props =>
    auth.isAuthenticated === false  ? (
      <Redirect to="/login" />
      
    ) : (
      <Component {...props} />
    )
  }
/>
);
PrivateRoute.propTypes = {
  auth: PropTypes.object.isRequired
};
const mapStateToProps = state => ({
  auth: state.auth
});


export default connect(mapStateToProps)(PrivateRoute);

Answer 1

您能否尝试移除 component={Dashboard} 道具，而仅使用渲染道具来渲染仪表板。你的代码应该是这样的

  <PrivateRoute exact path="/dashboard" render={routeProps =>
            <Dashboard
            handleUpdate={this.handleUpdate}
            book={this.state.book}
            info={this.state.info}
            {...routeProps} />}
          />

Answer 2

你能给我们展示一下 PrivateRouter 组件的代码吗？你可以按照这样的方式

<PrivateRoute exact path="/dashboard" component={Dashboard} props = {{book: this.state.book etc}}/>

并在 PrivateRoute 组件上接收这个 props 将其放入子组件

来自docs

<块引用>

警告：<Route component> 的优先级高于 <Route render>，所以不要在同一个 .

因此，删除 component={Dashboard}

在注释和 PrivateRoute 代码之后，我建议您将 PrivateRoute 重写为

const PrivateRoute = ({ auth, ...rest }) => {
  if (!auth.isAuthenticated) {
    return <Redirect to="/login" />;
  }

  return <Route {...rest} />
);

并删除 component={Dashboard} 部分。

Answer 4

const PrivateRoute = ({component: Component, auth, book, handleUpdate, ...rest }) => (
  console.log(rest),
  console.log(book),

  <Route
  {...rest}
  render={props =>
    auth.isAuthenticated === false  ? (
      <Redirect to="/login" />
  
) : (
  <Component book={book} handleUpdate={handleUpdate} {...props} />
)

} /> )
