【问题标题】:using history with react-router-dom v6在 react-router-dom v6 中使用历史
【发布时间】:2020-12-07 20:00:56
【问题描述】:

我使用 react-router-dom version 6 而当我使用 this.props.history.push('/UserDashboard') 时它不起作用。我把它改成

const history = createBrowserHistory();
history.push('/UserDashboard')

但我仍然有一个问题,当我想重定向到/UserDashboard 时,只是链接更改并且页面仍然是第一个??

有什么帮助吗??**

        handleSubmit(event){
       
    
        event.preventDefault();
        const history = createBrowserHistory();
        axios({
          method: "POST", 
          url:"http://localhost:3001/users/login", 
          data:  this.state
        }).then((response)=>{
          console.log(response.data.user.admin)
          if (response.data.success === true && response.data.user.admin === false){
           
                  const history = createBrowserHistory();
                  history.push({
                   pathname:"/users",
                   state:{
                   Key : response.data.user }
     });
    
        
           
          }else if(response.statusCode === 401 ){
            alert("Invalid username or password");
           window.location.reload(false);
          }
        })
      }

我的 routes.js 文件:

    import React from 'react';
    import { Navigate } from 'react-router-dom';
    import DashboardLayout from './Pages/DashboardLayout';
    import AccountView from './Pages/views/account/AccountView';
    import CustomerListView from './Pages/views/customer/CustomerListView';
    import DashboardView from './Pages/views/reports/DashboardView';
    import ProductListView from './Pages/views/product/ProductListView';
    import SettingsView from './Pages/views/settings/SettingsView';
    import Home from './Pages/home';
    import About from './Pages/About';
    import Partners from './Pages/Partners';
    import Services from './Pages/services';
    import Login from './Pages/Login';
    import RD from './Pages/RD';
    import ContactUs from './Pages/contactus';
    import Apply from './Pages/apply';
    import PartnerShip from './Pages/partnership';
    import News from './Pages/News';
    const routes = [
     {
     path: 'users',
     element: <DashboardLayout />,
     children: [
      { path: 'account', element: <AccountView /> },
      { path: 'customers', element: <CustomerListView /> },
      { path: 'dashboard', element: <DashboardView /> },
      { path: 'products', element: <ProductListView /> },
      { path: 'settings', element: <SettingsView /> }
      ]
     },
    {
    path: '/',
    element: <Home />,
    },
    {
    path: 'about',
    element: <About />
    },
     {path: 'partners',
     element: <Partners />,
    
    },
    {
    path: 'services',
    element: <Services />,
    
    },
    {
    path: 'contactus',
    element: <ContactUs />,
    
    },
    {
    path: 'login',
    element: <Login />,
    
     },{
    path: 'RD',
    element: <RD />,
    
    },
    {
    path: 'apply',
    element: <Apply />,
    
     },
     {
    path: 'partnership',
    element: <PartnerShip />,
    
     },
     {
    path: 'News',
    element: <News />,
    
     }
    ];

    export default routes;

【问题讨论】:

  • 您是否尝试在功能组件或类的开头更改 const history = createBrowserHistory()?
  • 是的,但它不起作用
  • 你在使用历史钩子吗?因为你需要在 import { useHistory} from 'react-router-dom' 中声明它;并像这样使用它: const history = useHistory()
  • 您可以编辑您的代码并放置您的路由文件吗?
  • 不,问题是我使用 react-router-dom@6 版本 6,所以当我使用 useHistory() 时出现此错误 Attempted import error: 'useHistory' is not export from 'react -router-dom'。

【解决方案1】:

在 react-router-dom v6 中,您需要使用 useNavigate 而不是 useHistory。

参见https://reacttraining.com/blog/react-router-v6-pre/的示例

import React from 'react';
import { useNavigate } from 'react-router-dom';

function App() {
  let navigate = useNavigate();
  let [error, setError] = React.useState(null);

  async function handleSubmit(event) {
    event.preventDefault();
    let result = await submitForm(event.target);
    if (result.error) {
      setError(result.error);
    } else {
      navigate('success');
    }
  }

  return (
    <form onSubmit={handleSubmit}>
      // ...
    </form>
  );
}

【讨论】:

  • 问题是,我们如何从外部组件导航?例如。当我们的逻辑在actions内时?
  • @Eduard 看看我的回答。这应该可以解决您的问题。
【解决方案2】:

基于 react-router-dom 源代码,你可以这样做:

const CustomRouter = ({
  basename,
  children,
  history,
}) => {
  const [state, setState] = React.useState({
    action: history.action,
    location: history.location,
  });

  React.useLayoutEffect(() => history.listen(setState), [history]);

  return (
    <Router
      basename={basename}
      children={children}
      location={state.location}
      navigationType={state.action}
      navigator={history}
    />
  );
};

然后让你的历史来自外部:

const history = createBrowserHistory();
<CustomRouter history={history}>
 ...
</CustomRouter>

【讨论】:

  • 嘿@poyoman,您将如何使用基于类的组件来实现相同的目标。我不使用功能组件。
  • @Fonty 把我的功能组件放在你的类组件的“render”方法里面:)
  • 谢谢@poyoman,我会试一试。最好使用最新版本。
【解决方案3】:

我们都知道 react-router-dom v6 中不再有 { useHistory } 之类的东西。有更好的方法来完成 useHistory 的工作。

首先导入 useNavigate ...

import { useNavigate } from 'react-router-dom';

然后在导入后执行此操作

function Test() {
    const history = useNavigate();

    function handleSubmit(e) {
        e.preventDefault();

        history('/home');
    }

    return (
        <form onSubmit={handleSubmit}>
            <button>Subimt</button>
        </form>
    )
}
