如何在我的路由中定义路由。jsx文件捕获__firebase_request_key参数值从一个URL生成的Twitter的单点登录过程后,从他们的服务器重定向?

http://localhost:8000/#/signin?_k=v9ifuf&__firebase_request_key=blablabla

我尝试了以下路由配置,但:redirectParam没有捕获提到的参数:

<Router>
  <Route path="/" component={Main}>
    <Route path="signin" component={SignIn}>
      <Route path=":redirectParam" component={TwitterSsoButton} />
    </Route>
  </Route>
</Router>

当前回答

let data = new FormData();
data.append('file', values.file);

React路由器Dom V6 https://reactrouter.com/docs/en/v6/hooks/use-search-params

import * as React from "react";
import { useSearchParams } from "react-router-dom";

function App() {
  let [searchParams, setSearchParams] = useSearchParams();

  function handleSubmit(event) {
    event.preventDefault();
    // The serialize function here would be responsible for
    // creating an object of { key: value } pairs from the
    // fields in the form that make up the query.
    let params = serializeFormQuery(event.target);
    setSearchParams(params);
  }

  return (
    <div>
      <form onSubmit={handleSubmit}>{/* ... */}</form>
    </div>
  );
}

直到React路由器Dom V5

function useQueryParams() {
    const params = new URLSearchParams(
      window ? window.location.search : {}
    );

    return new Proxy(params, {
        get(target, prop) {
            return target.get(prop)
        },
    });
}

React钩子很棒

如果你的url看起来像/users?页面= 2数= 10字段=姓名、电子邮件、电话

// app.domain.com/users?page=2&count=10&fields=name,email,phone

const { page, fields, count, ...unknown } = useQueryParams();

console.log({ page, fields, count })
console.log({ unknown })

如果您的查询参数包含hyphone("-")或空格(" ") 然后你不能像{page, fields, count,…未知的}

你需要做传统的作业,比如

// app.domain.com/users?utm-source=stackOverFlow

const params = useQueryParams();

console.log(params['utm-source']);

在没有第三方库或复杂的解决方案的情况下,在一行中完成这一切。以下是如何

let myVariable = new URLSearchParams(history.location.search).get('business');

你唯一需要改变的是你自己的参数名称的单词“business”。

业务= url.com例子吗?你好

myVariable的结果将是hello

在需要访问可以使用的参数的组件中

this.props.location.state.from.search

这将显示整个查询字符串(在?标志)

在typescript中,参见下面的示例片段:

const getQueryParams = (s?: string): Map<string, string> => {
  if (!s || typeof s !== 'string' || s.length < 2) {
    return new Map();
  }

  const a: [string, string][] = s
    .substr(1) // remove `?`
    .split('&') // split by `&`
    .map(x => {
      const a = x.split('=');
      return [a[0], a[1]];
    }); // split by `=`

  return new Map(a);
};

在react中使用react-router-dom,你可以做

const {useLocation} from 'react-router-dom';
const s = useLocation().search;
const m = getQueryParams(s);

参见下面的例子

//下面是上面转换和缩小的ts函数 如果(const getQueryParams = t = > {! t | |“字符串”!=typeof t||t.length<2)return new Map;const r=t.substr(1).split("&")。地图(t = > {const r = t.split(" = ");返回[r[0],[1]]});返回新地图(r)}; //一个示例查询字符串 Const s = '?__arg1 = value1&arg2 = value2 ' getQueryParams(s) console.log (m.get (__arg1)) console.log (m.get(最长)) Console.log (m.t get('arg3')) //不存在,返回undefined

如果你的路由器是这样的

<Route exact path="/category/:id" component={ProductList}/>

你会得到这样的id

this.props.match.params.id
