javascript - TypeError : this. props.history 不是导航共享组件内的函数

Question

我有以下导航组件

import React, { Component } from "react";
import { NavLink, withRouter } from "react-router-dom";
import swal from "sweetalert";

import CollectionsDropdown from "./CollectionsDropdown";
import Logo from "../../../images/logo.png";

import AuthService from "../../Auth/AuthService";
const Auth = new AuthService();

class Navigation extends Component {
  state = {
    toggle: false,
    categorys: []
  };

  Toggle = () => {
    this.setState({ toggle: !this.state.toggle });
  };

  handleLogout(props) {
    Auth.logout();
    swal({
      title: "Logged out",
      text: "You have successfully logged out",
      icon: "success",
      buttons: true
    });
    this.props.history("/");
  }

  render() {
    return (
      <>
        <nav className='flex items-center justify-between flex-wrap text-gray-800 bg-white p-6 border-b md:block md:justify-start md:text-center'>

          </div>

          <div

              {Auth.loggedIn() ? (

              ) : (

                  <NavLink
                    to='/about'

                    className='nav-link transition-all ease-out transition-small'

                  >
                    Journals

                  <NavLink

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

export default withRouter(Navigation);

以及以下app.js

import React, { Component } from "react";
import { Route, Switch, withRouter } from "react-router-dom";

// App imports
import Navigation from "./components/shared/Navigation/Navigation";
import Footer from "./components/shared/Footer";

import PageNotFound from "./components/PageNotFound";

import About from "./components/About";
import Contact from "./components/Contact";

import Collections from "./components/Collections/landing";
import CollectionShow from "./components/Collections/show";
import CollectionCreate from "./components/Dashboard/Collections/create";
import CollectionsEdit from "./components/Dashboard/Collections/edit";

import Journals from "./components/Journals/landing";
import JournalShow from "./components/Journals/show";
import JournalCreate from "./components/Dashboard/Journals/create";
import JournalEdit from "./components/Dashboard/Journals/edit";

// Auth
import Register from "./components/Auth/Register";
import Login from "./components/Auth/Login";

class App extends Component {
  render() {
    return (
      <>
        <Navigation />

        <div className='flex-1'>
          <Switch>
            <Route exact path='/about' component={About} />
            <Route exact path='/contact' component={Contact} />

            <Route exact path='/collections' component={Collections} />
            <Route exact path='/collections/:id' component={CollectionShow} />

            <Route
              exact
              path='/dashboard/collections/create'
              component={CollectionCreate}
            />
            <Route
              exact
              path='/dashboard/collections/:id/edit'
              component={CollectionsEdit}
            />

            <Route exact path='/journals' component={Journals} />
            <Route exact path='/journals/:id' component={JournalShow} />

            <Route
              exact
              path='/dashboard/journals/create'
              component={JournalCreate}
            />
            <Route
              exact
              path='/dashboard/journals/:id/edit'
              component={JournalEdit}
            />

            <Route exact path='/auth/register' component={Register} />
            <Route exact path='/auth/login' component={Login} />

            <Route path='*' component={PageNotFound} />
          </Switch>
        </div>

        <Footer />
      </>
    );
  }
}

export default withRouter(App);

我尝试在注销后将用户重定向到主页，但收到 TypeError(在标题中)

我没有对react-router-dom做太多事情，所以不太确定我哪里出了问题。

导航是一个嵌套组件，所以我希望有一种方法可以轻松地传递 props。

所以任何帮助都会很棒。

Answer 1

我相信你忘记使用“push”

所以而不是

this.props.history("/") 

使用

this.props.history.push("/")
