javascript - NextJS React 应用程序样式组件未正确渲染 : Warning: Prop `className` did not match

Question

在我的 NextJS 应用程序的 _app.tsx 中，我使用 从 'next/router' 导入 Router 以便为我的顶部菜单呈现不同的导航按钮样式。

当路径为 / 时，渲染有效，但是当我位于 /about 时，渲染不起作用，并且出现以下错误。即使 bool 逻辑工作正常。

错误:

Warning: Prop className did not match. Server: "nav__NavActive-sc-6btkfp-2 gJVDzS nav__NavLink-sc-6btkfp-1 bvpMWI" Client: "nav__NavLink-sc-6btkfp-1 bvpMWI"

在下面的屏幕截图中，我当前位于 /about 路径上，并且 NavActive 样式应应用于 about 链接，但事实并非如此。

关于页面上的 bool console.logs:

但是 NavActive 样式仍然停留在 portfolio 上，即 '/' 路线。

_app.tsx

import React from 'react'
import Router from 'next/router'
import App, { Container } from 'next/app'
import withReduxStore from '../lib/withReduxStore'
import { Provider } from 'react-redux'

import Page from '../components/Page/Page'
import { Nav, NavLink, NavActive } from '../styles'

interface IProps {
  reduxStore: any;
  location: string;
}

const pluckRoute = (Router: any) => Router ? Router.pathname : '/';

class MoonApp extends App<IProps> {
  render() {
    const { Component, reduxStore } = this.props;

    const currentRoute = pluckRoute(Router.router);
    console.log('currentRoute', currentRoute);

    const NavPortfolio = currentRoute === '/' ? NavActive : NavLink;
    const NavAbout = currentRoute === '/about' ? NavActive : NavLink;

    console.log(currentRoute === '/');
    console.log(currentRoute === '/about');

    return (
      <Container>
        <Provider store={reduxStore}>
          <Page>
            <Nav>
              <ul>
                <li><NavPortfolio href="/">Portfolio</NavPortfolio></li>
                <li><NavAbout href="/about">About</NavAbout></li>
              </ul>
            </Nav>
            <Component />
          </Page>
        </Provider>
      </Container>
    )
  }
}

export default withReduxStore(MoonApp);

我的导航样式

import styled from 'styled-components'

export const Nav = styled.div`
  width: 100px;

  ul {
    display: flex;
    flex-direction: row;
    justify-content: space-between;
    margin: 30px 0 0 30px;
  }

  li { margin-right: 1.5rem; list-style: none; }
`

export const NavLink = styled.a`
  color: ${props => props.theme.apricot};
  border: none;
  &:hover { color: ${props => props.theme.offWhite}; }
`

export const NavActive = styled(NavLink)`
  color: ${props => props.theme.offWhite};
  border-bottom: 2px solid ${props => props.theme.apricot};
`

试试这个怎么样？

import Link from 'next/link'

...

const pluckRoute = (Router: any) => Router ? Router.pathname : '/';

...

const currentRoute = pluckRoute(Router.router);
const NavPortfolio = currentRoute === '/' ? NavActive : NavLink;
const NavAbout = currentRoute === '/about' ? NavActive : NavLink;

...


<li>
  <Link href={`/`}>
    <NavPortfolio>Portfolio</NavPortfolio>
  </Link>
</li>
<li>
  <Link href={`/about`}>
    <NavAbout>About</NavAbout>
  </Link>
</li>
