react-router-dom v6 路由参数

1.通过state传参(HashRouter会丢失，BrowserRouter不会丢失)

传参页面

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

const navigate = useNavigate()

navigate("/home",{state:{id:123}})

接收页面

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

const location = useLocation()

const back = () => {
    console.log(location.state.id) //打印结果为123
}

由于state刷新后值还存在，有时需要删除值

useEffect(() => {
    if (location.state?.id) {
      form.setFieldsValue({ id: location.state.id});
      let state = { ...location.state };
      delete state.id;

        navigate({ ...location, state });

    }
  }, [form, history, location]);

2. 问号（？）形式传参（跳转新标签页只能用此携带参数）

传参页面

import { useNavigate, createSearchParams } from "react-router-dom";

const navigate = useNavigate()

navigate("/home?id=123")

navigate({
    pathname: "/home", search: `?id=123` 
})

navigate({
    pathname: "/home",
    search: `?${createSearchParams({id:123})}`
})

接收页面

import { useSearchParams } from "react-router-dom";

const [searchParams, setSearchParams] = useSearchParams();

const back = () => {
    console.log(searchParams.getAll('id')[0])  //打印结果为 123
    setSearchParams();  
}

3.params传参 (restful格式)，需要在Route上显示写明 :params

传参页面

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

<Route path={'/home/:id'} element={<ToPage/>} />

navigate(`/home/${id}`)

接收页面

import { useParams } from "react-router-dom";

const ToPages = () => {
const { id } = useParams();
console.log(id)
}
