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

所以我正在开发一个 nodejs 应用程序，我将在该应用程序上安装我的新网站，并且我想为客户端的用户提供一种显示不同内容的方式，并根据用户按下的内容重新呈现.我的想法是，例如，首先用户会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，然后页面将被重新渲染并显示在 jumbotron 内选择的工具，其 url 为例如然后更改/admin/[ToolSelected].

唯一的问题是我不知道如何实现这一点.我在想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，然后该工具将根据页面变量的内容显示一个 IF 语句.

我的理论是否可行，或者如何以有效的方式实现这一目标?

这是我的主页代码:

//包括导航栏和css从../comps/admin/adminLayout"导入 AdminLayout//所谓的工具"更多将在未来存在从../comps/admin/tools/passform"导入密码//获取用户当前所在的urlvar page = CURRENT_URL;常量 jumbotron = {背景:白色"}const Admin = (page) =>(<管理布局><风格全局 jsx>{`身体{背景:#eff0f3；}`}</风格><div className="jumbotron" 样式={jumbotron}>{(page == "passform") ?(<通行证/>) : (<h3>出了点问题:/.{page}</h3>)}</div></管理布局>)导出默认管理员

解决方案

你可以用 withRouter HOC，将注入具有当前 pathname 的 router 对象.

import { withRouter } from 'next/router';const Admin = ({ 路由器 }) =>(<管理布局><风格全局 jsx>{`身体 {背景:#eff0f3；}`}</风格>

编辑

如果你更喜欢钩子，你可以使用 useRouter 钩子.

import { useRouter } from 'next/router';const Admin = () =>{常量路由器 = useRouter();返回 (<管理布局><风格全局 jsx>{`身体 {背景:#eff0f3；}`}</风格>

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].

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.

Would my theory work or how can a achieve this in an efficient way?

Here is my main page code:

// 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

解决方案

You can wrap your component with withRouter HOC, that will inject the router object, that has current pathname.

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);

Edit

If you prefer hooks you can use useRouter hook.

import { useRouter } 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 Admin;
