我尝试使用 react 中的 useHistory 钩子，但它不起作用；

Question

App.js

import { Route, Router, Switch } from 'react-router-dom'
import Login from './Pages/Login';
import Profile from './Pages/Profile';
import Routes from './Routes1/Route';



function App() {
  return (
    <div className="App">
    <Routes />
    </div>
    
  );
}

export default App;

Route.js

import React from 'react';
import { Router, Route, Switch } from 'react-router-dom';
import { createBrowserHistory } from 'history';
import Login from '../Pages/Login';
import Profile from '../Pages/Profile';



const Routes = () => {
    const history = createBrowserHistory();
    return (
        <Router history={history}>
            <Switch>
                <Route path="/login" component={Login} />
                <Route path="/profile" component={Profile} />
            </Switch>
        </Router>
    );
}

export default Routes;

Login.js

import React from 'react'
import {useHistory} from 'react-router-dom'

function Login() {
        
        const history=useHistory();
        const handleHistory=() =>{
            history.push("/profile")
        }
    return (
        <div>
            <input type="text" placeholder="username" />
            <input typ="text" placeholder="password" />
            <button onClick={handleHistory}> Submit </button>
        </div>
    )
}

export default Login

Profile.js

import React from 'react'

function Profile() {
    return (
        <div>
            Congratulations! You have successfully logged in!
        </div>
    )
}

export default Profile

错误 错误：无效的挂钩调用。 Hooks 只能在函数组件的主体内部调用。这可能是由于以下原因之一：

1. 您可能有不匹配的 React 版本和渲染器（例如 React DOM）
2. 您可能违反了 Hooks 规则
3. 您可能在同一个应用程序中拥有多个 React 副本 有关如何调试和解决此问题的提示，请参阅 https://reactjs.org/link/invalid-hook-call。

Answer 1

我不确定import { createBrowserHistory } from 'history';，但你的代码应该可以在没有它的情况下工作，并且BrowserRouter 作为路由器：

Route.js

import React from 'react';
import { BrowserRouter as Router, Route, Switch } from 'react-router-dom';
import Login from '../Pages/Login';
import Profile from '../Pages/Profile';



const Routes = () => {
    return (
        <Router>
            <Switch>
                <Route path="/login" component={Login} />
                <Route path="/profile" component={Profile} />
            </Switch>
        </Router>
    );
}

Answer 2

我在您的代码中看不到任何错误，但是，您不需要 Routes 组件中的历史记录来达到此目的，请尝试删除以下行：

const history = createBrowserHistory() 

和路由器中的历史道具。 或者不要创建handleSubmit 函数，而是尝试在onClick 处传递directly () => history.push()。
