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>

我使用了一个名为query-string的外部包来解析url参数,如下所示。

import React, {Component} from 'react'
import { parse } from 'query-string';

resetPass() {
    const {password} = this.state;
    this.setState({fetching: true, error: undefined});
    const query = parse(location.search);
    return fetch(settings.urls.update_password, {
        method: 'POST',
        headers: {'Content-Type': 'application/json', 'Authorization': query.token},
        mode: 'cors',
        body: JSON.stringify({password})
    })
        .then(response=>response.json())
        .then(json=>{
            if (json.error)
                throw Error(json.error.message || 'Unknown fetch error');
            this.setState({fetching: false, error: undefined, changePassword: true});
        })
        .catch(error=>this.setState({fetching: false, error: error.message}));
}

其他回答

componentDidMount(){
    //http://localhost:3000/service/anas
    //<Route path="/service/:serviceName" component={Service} />
    const {params} =this.props.match;
    this.setState({ 
        title: params.serviceName ,
        content: data.Content
    })
}

最简单的解决方案!

在路由方面:

   <Route path="/app/someUrl/:id" exact component={binder} />

在react代码中:

componentDidMount() {
    var id = window.location.href.split('/')[window.location.href.split('/').length - 1];
    var queryString = "http://url/api/controller/" + id
    $.getJSON(queryString)
      .then(res => {
        this.setState({ data: res });
      });
  }
let data = new FormData();
data.append('file', values.file);

有了这一行代码,你可以在React Hook和React Class Component的任何地方使用它。

let city = (new URLSearchParams(window.location.search)).get("city")

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');
