在next.js中获取客户端的当前URL [英] Getting the current url on the client side in next.js

问题描述

因此，我正在开发一个nodejs应用程序，我将在其上拥有新网站，并且我想为我的用户提供一种方法，使其在客户端显示不同的内容，并根据用户所按下的内容进行重新渲染.我的想法是，例如，首先用户将看到请先选择一个工具"，然后用户将在导航栏中选择一个工具，然后将重新渲染该页面，并在巨无霸内显示所选工具，其网址为例如，先更改为/admin/[ToolSelected].

So I am working on a nodejs app which I will have my new website on and I want to make a way for my user on the clientside to display different things, re-renderd depending on what the user is pressing on. My idea is that for example firstly the user would see "Please select a tool first" and then the user will select a tool in the navbar which then the page will be re-renderd and display the tool selected inside a jumbotron with the url being changed for example then /admin/[ToolSelected].

唯一的原因是我不知道如何实现这一目标.我以为客户端代码可以检测到url是什么，并将其作为页面变量放置，然后根据页面变量是什么，该工具将与IF语句一起显示.

The only thing is tho that I do not know how to achieve this. I was thinking that the client side code could detect what the url is and is placed as a page variable then the tool will displayed with a IF statement depending on what the page variable is.

我的理论会起作用吗?或者如何有效地实现这一目标?

这是我的主页代码:

// Including Navbar and css
import AdminLayout from '../comps/admin/adminLayout'

// the so called "tools" more will exist in the future
import Passform from '../comps/admin/tools/passform'


// Fetching the current url the user is on
var page = CURRENT_URL;


const jumbotron = {
  background: 'white'
}

const Admin = (page) => (

  <AdminLayout>

  <style global jsx>
  {
    `body {
      background: #eff0f3;
    }`
  }
  </style>
    <div className="jumbotron" style={jumbotron}>

    {(page == "passform") ? (
      <Passform/>
    ) : (
      <h3>Something is wrong :/ . {page}</h3>
    )}

    </div>
  </AdminLayout>
)

export default Admin

推荐答案

您可以使用 withRouter HOC，它将注入具有当前pathname的router对象.

import { withRouter } from 'next/router';

const Admin = ({ router }) => (
  <AdminLayout>
    <style global jsx>
      {`
        body {
          background: #eff0f3;
        }
      `}
    </style>
    <div className="jumbotron" style={jumbotron}>
      {router.pathname == 'passform' ? <Passform /> : <h3>Something is wrong :/ . {page}</h3>}
    </div>
  </AdminLayout>
);

export default withRouter(Admin);

修改

如果您喜欢钩子，则可以使用 useRouter 钩子

If you prefer hooks you can use useRouter hook.

import { userRouter } from 'next/router';

const Admin = () => {
const router = useRouter();

return (
  <AdminLayout>
    <style global jsx>
      {`
        body {
          background: #eff0f3;
        }
      `}
    </style>
    <div className="jumbotron" style={jumbotron}>
      {router.pathname == 'passform' ? <Passform /> : <h3>Something is wrong :/ . {page}</h3>}
    </div>
  </AdminLayout>);
}
;

export default withRouter(Admin);
