思路：利用react-route-dom的history.block进行锁定
注意：6版本的react-route-dom history.block的返回值是解锁函数，return无效
效果：项目内的路由操作都可以执行自己的组件，游览器url操作会执行原生对话框

import React, { useEffect, useState } from "react";
import { Routes, Route } from "react-router-dom";
import { confirm } from 'xx-design';

import ProjectViewer from './page/car/project';
// ...若干引入...

const RouteViewer = (props) => {
  const { history } = props;
  const [lock, changeLock] = useState(false);
  const [location, changeLocation] = useState(history.location);

  useEffect(() => {
    const unListen = history.listen(({ location: newLocation }) => {
      if (newLocation) {
        changeLocation(newLocation);
      }
    });
    return () => {
      unListen();
    }
  }, [])
  useEffect(() => {
    let unBlock;
    if (lock) {
      // 上锁
      unBlock = history.block(({ location: nextLocation }) => {
        // 自己的弹窗组件
        confirm({
          content: '退出后，未上传的视频将不再继续上传！</br>确定退出吗？',
          onOk: () => {
            changeLock(false);
            unBlock();
             // 解锁后继续跳转
            history.push(nextLocation.pathname);
          },
        });
      });
    } else {
      unBlock && unBlock(); // 解锁
    }
  }, [lock])
  return (
    <Routes location={location}>
      <Route path="/" group="car" element={<ProjectViewer history={history} />} />
      <Route path="/car" group="car" element={<ProjectViewer history={history} />} />
      ...若干路由...
      <Route path="devicesHistory/:name" group="console" element={<DevicesHistory changeLock={changeLock} history={props.history} />} />
      <Route path="*" element={<main style={{ padding: '1rem' }}><p>404</p></main>} />
    </Routes>
  );
}

export default RouteViewer;

import React, { useState, useEffect } from "react";
import { connect } from "react-redux";

const Viewer = (props) => {
  const handlerDis = () => {
// 点击上锁
     props.changeLock(true);
  }
  useEffect(() => {
   return () => {
// 卸载的时候解锁
      changeLock(false);
    }
  }, []);

  return (
    <div><button onClick={handlerDis}>点击上锁</button></div>
  );
};

export default  (Viewer);
