错误：useHref()只能在路由器&>组件的上下文中使用 [英] Error: useHref() may be used only in the context of a <Router> component

问题描述

**当我将我的导航栏组件内容直接写入我的路由器组件时。它工作得很好，但当我在NavBar组件中编写该内容时，它会生成以下错误

错误：useHref()只能在组件的上下文中使用。 .**

我正在使用 "react-dom": "^17.0.2", "react-router-dom": "^6.0.0-beta.6",

以下是我的组件..

我的导航栏组件：-

import { Link } from "react-router-dom";
// import styles from './NavBar.module.css';
export const NavBar = () => {
  return (
      <nav>
        <Link to="/"> Home </Link>
        <Link to="/about"> About </Link>
        <Link to="/product"> Product </Link>
      </nav>
  );
}

我的路由组件：-

import { BrowserRouter as Router, Switch, Route, Routes} from "react-router-dom";

// importing Component's
import { Home } from "./Components/Home/Home";
import { About } from "./Components/About/About";
import { Products } from "./Components/Products/Products";
import { ProductItems } from "./Components/ProductItems/ProductItems";
import  {NavBar}  from "./Components/NavBar/NavBar";
import { Fotter } from "./Components/Fotter/Fotter";

export const RouterConfig = () => {
  return (
    <Router>
      <NavBar />
      <Switch>
        <Route exact path="/" component={Home} />
        <Route path="/about" component={About} />
        <Route exact path="/product" component={Products} />
        <Route path="/product/:id" component={ProductItems} />
        <Route path="*" component={() => <h2>404 Not Found </h2>} />
      </Switch>
      {/* <Fotter />' */}
    </Router>
  );
};

推荐答案

import {BrowserRouter as Router} from "react-router-dom";

在index.js中的组件App.js或更高版本中使用，并将组件包装在路由器中。 然后问题就会消失；-) 在您的案例中，我看到两个选项：

1. index.js

数据-lang="js"数据-隐藏="假"数据-控制台="真"数据-巴贝尔="假">

import React from "react";
import ReactDOM from "react-dom";
import App from "./App";
import { BrowserRouter as Router } from "react-router-dom";

ReactDOM.render(
  <React.StrictMode>
    <Router>
      <App />
    </Router>
  </React.StrictMode>,
  document.getElementById("root")
);

或使用应用组件而不是路由器配置组件。

2. App.js

数据-lang="js"数据-隐藏="假"数据-控制台="真"数据-巴贝尔="假">

import { BrowserRouter as Router, Switch, Route, Routes} from "react-router-dom";

// importing Component's
import { Home } from "./Components/Home/Home";
import { About } from "./Components/About/About";
import { Products } from "./Components/Products/Products";
import { ProductItems } from "./Components/ProductItems/ProductItems";
import  {NavBar}  from "./Components/NavBar/NavBar";
import { Fotter } from "./Components/Fotter/Fotter";

export const App = () => {
  return (
    <Router>
      <NavBar />
      <Switch>
        <Route exact path="/" component={Home} />
        <Route path="/about" component={About} />
        <Route exact path="/product" component={Products} />
        <Route path="/product/:id" component={ProductItems} />
        <Route path="*" component={() => <h2>404 Not Found </h2>} />
      </Switch>
      {/* <Fotter />' */}
    </Router>
  );
};

我尽我所能地解释了。希望这对你有帮助；-)致以最好的问候和好运！ 如果您仍然不明白，请点击此处查看。 React Router V6 - Error: useRoutes() may be used only in the context of a <Router> component
