Long path fails to load with react-router-dom

问题

I have a VerifyEmail route that takes on a JWT token as a parameter. However, it does not load. Is there anyway to get it to load? The route loads if the token is short, about 10 characters long. Anything longer it does not work. I was wondering if there's a limit to the length of the url path for react-router-dom to be causing this problem.

In my App.jsx

import React from "react";
import { BrowserRouter, Routes, Route } from "react-router-dom";
import Home from "./components/Home";
import Login from "./components/Login";
import Logout from "./components/Logout";
import SignUp from "./components/SignUp";
import Navbar from "./components/Navbar";
import VerifyEmail from "./features/users/VerifyEmail";
import { selectCurrentToken } from './features/auth/authSlice';
import { useSelector } from "react-redux/es/hooks/useSelector";

function App() {
  const auth = useSelector(selectCurrentToken)

  return (
    <>
      <BrowserRouter>
        <Navbar auth={auth} />
        <Routes>
          <Route index element={<Home />} />
          {!auth && <Route path="/login" element={<Login />} />}
          {auth && <Route path="/logout" element={<Logout />} />}
          <Route path="/signup" element={<SignUp />} />
          <Route path="/verify/:token" element={<VerifyEmail />} />
        </Routes>
      </BrowserRouter>
    </>
  )
}

export default App

In my VerifyEmail.jsx

import React from 'react'
import { useParams } from 'react-router-dom'

const VerifyEmail = () => {
  const { token } = useParams()

  return (
    <div>{token}</div>
  )
}

export default VerifyEmail

When I try this link, I get a bad request.

网络服务器错误地将您的JWT与文件混淆。它如何区分localhost:5173/favicon.icolocalhost:5173/U3MDYyN30.HqPtksRbGTxxP8EeFs7之间的区别?因此,它会抛出一个Not Found错误,就像您在图像中所显示的那样。您有两种处理方法:

  1. 如果您正在使用webpack,您可以配置以禁用点规则(文档)。
 historyApiFallback: {
    disableDotRule: true
 }
  1. 您可以修改路由并将JWT作为查询参数传递
<Route path="/verify" element={<VerifyEmail />} />

然后在您的VerifyEmail组件中,使用useQuery来获取token的值

// http://localhost:5173/verify?token=abcxyx
import { useQuery } from 'react-router-dom';

function VerifyEmail() {
   let query = useQuery();
   let token = query.get('token');

   // 您组件逻辑的其余部分
}
英文:

The web server is misinterpret your jwt with a file. How is it know the difference between locahost:5173/favicon.ico and localhost:5173/U3MDYyN30.HqPtksRbGTxxP8EeFs7. So it will throw an error Not Found as you show in the image. You have two options to handle this:

  1. If you are using webpack, you can config to disable the dot rule (docs).
 historyApiFallback: {
    disableDotRule: true
 }
  1. You can modify the route and pass the JWT as a query parameter
&lt;Route path=&quot;/verify&quot; element={&lt;VerifyEmail /&gt;} /&gt;

And in your VerifyEmail component, use useQuery to get the value of token

// http://localhost:5173/verify?token=abcxyx
import { useQuery } from &#39;react-router-dom&#39;;

function VerifyEmail() {
   let query = useQuery();
   let token = query.get(&#39;token&#39;);

   // Rest of your component logic
}
