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

React路由器v5.1引入了钩子:

For

<Route path="/posts/:id">
  <BlogPost />
</Route>

你可以通过hook访问params / id:

const { id } = useParams();

this.props.params。Your_param_name将工作。

这是从查询字符串中获取参数的方法。 请执行console.log(this.props);探索所有的可能性。

如果你没有得到这个。道具…根据其他答案,您可能需要使用withthrouter (docs v4):

import React from 'react'
import PropTypes from 'prop-types'
import { withRouter } from 'react-router'

// A simple component that shows the pathname of the current location
class ShowTheLocation extends React.Component {
  static propTypes = {
    match: PropTypes.object.isRequired,
    location: PropTypes.object.isRequired,
    history: PropTypes.object.isRequired
  }

  render() {
    const { match, location, history } = this.props

    return (
      <div>You are now at {location.pathname}</div>
    )
  }
}

// Create a new component that is "connected" (to borrow redux terminology) to the router.  
const TwitterSsoButton = withRouter(ShowTheLocation)  

// This gets around shouldComponentUpdate
withRouter(connect(...)(MyComponent))

// This does not
connect(...)(withRouter(MyComponent))

试试这个

http://localhost:4000/#/amoos?id=101

// ReactJS
import React from "react";
import { useLocation } from "react-router-dom";

const MyComponent = () => {
    const search = useLocation().search;
    const id = new URLSearchParams(search).get("id");
    console.log(id); //101
}



// VanillaJS
const id = window.location.search.split("=")[1];
console.log(id); //101

你可以使用这个用Typescript写的简单钩子:

const useQueryParams = (query: string = null) => {      
    const result: Record<string, string> = {};
    new URLSearchParams(query||window.location.search).forEach((value, key) => {
      result[key] = value;
    });
    return result;
}

用法:

// http://localhost:3000/?userId=1889&num=112
const { userId, num } = useQueryParams();
// OR
const params = useQueryParams('userId=1889&num=112');
