如何更改create-react应用程序的基本url

Question

我正在使用react路由器dom创建react应用程序。

用yarn start运行脚本从http://localhost:3000/(myprojectname)开始，不是http://localhost:3000/

当使用react router dom进行路由时，我必须从url中删除myprojectname，然后添加页面路由。

项目的初始设置似乎有问题

如何从http://localhost:3000/开始？？

添加package.json，路由器代码。

package.json:

{
"name": "cau-burger-online-order-system",
"version": "0.1.0",
"private": true,
"dependencies": {
"@testing-library/jest-dom": "^5.11.4",

},
"eslintConfig": {

},

],
"development": [
"last 1 chrome version",
"last 1 firefox version",
"last 1 safari version"
]
},
"homepage": "https://myprojectname"
}

App.tsx:

import '../node_modules/bootstrap/dist/css/bootstrap.min.css'
import './App.css'
import { Route, BrowserRouter as Router, Switch } from 'react-router-dom'
import Detail from 'pages/detail/Detail'
import GlobalStyle from './GlobalStyle'
import Home from 'pages/home/Home'
import Login from 'pages/login'
import Signup from 'pages/signup'
function App() {
return (
<Router>
<GlobalStyle />
<div className="App">
<div className="auth-wrapper">
<Switch>
<Route exact path="/" component={Login} />
<Route path="/login" component={Login} />
<Route path="/signup" component={Signup} />
<Route path="/home" component={Home} />
<Route path="/detail" component={Detail} />
</Switch>
</div>
</div>
</Router>
)
}
export default App

在package.json文件中，将homepage条目更改为相对路径，不包括任何子域/嵌套目录。

{
"name": "cau-burger-online-order-system",
"version": "0.1.0",
"private": true,
"dependencies": {
....
},
"scripts": {
...
},
...,
"homepage": "https://hy57in.github.io/2021-Industry-Hands-On-Project"
}

至

{
"name": "cau-burger-online-order-system",
"version": "0.1.0",
"private": true,
"dependencies": {
...
},
"scripts": {
...
},
...,
"homepage": "./"
}

我在https://v5.reactrouter.com/web/api/Redirect"渲染将导航到新位置。新站点将像服务器端重定向(HTTP 3xx(那样覆盖历史堆栈中的当前位置；

有什么方法可以共享您的存储库吗？我将是帮助你的最佳方式。差不多，我需要更多的信息来帮助你。

您只需要做两件事就可以更改ReactRouterDom的基本Url。当你在像github页面这样的网站上或在像H这样的url上托管网站时，它很有用ttps://website.com/mywebsite或者在子链路上。

首先-你必须添加一个属性像-

<BrowserRouter basename='/mywebsite'>

或者打开你的package.json并添加Before building your project for production

"homepage": "/your-subdirectory",

对于我的案例：

"homepage": "/mywebsite",

我希望这会有所帮助，请随意询问你是否陷入了困境。
