我们如何在React-Router v4中通过this.props.history.push('/page')传递参数?

.then(response => {
       var r = this;
        if (response.status >= 200 && response.status < 300) {
             r.props.history.push('/template');
          });

当前回答

我创建了一个自定义useQuery钩子

import { useLocation } from "react-router-dom";

const useQuery = (): URLSearchParams => {
  return new URLSearchParams(useLocation().search)
}

export default useQuery

使用它作为

const query = useQuery();
const id = query.get("id") as string

就这样发送

history.push({  
 pathname: "/template",
 search: `id=${values.id}`,
});
                  

其他回答

Pass

history.push({pathname:"/yourroute",state: {_id: "0001", name: "AZ"}})

Read

import React from 'react';

const YourRoute = props=> {
    const { _id, name } = (props.location && props.location.state) || {};
        //_id and name will contain the passed data
     .
     .
     .

}

下面是一个工作示例

添加信息以获取查询参数。

const queryParams = new URLSearchParams(this.props.location.search);
console.log('assuming query param is id', queryParams.get('id');

带有钩子的React TypeScript

来自班级

  this.history.push({
      pathname: "/unauthorized",
      state: { message: "Hello" },
    });

未经授权的功能组件

interface IState {
  message?: string;
}

export default function UnAuthorized() {
  const location = useLocation();
  const message = (location.state as IState).message;

  return (
    <div className="jumbotron">
      <h6>{message}</h6>
    </div>
  );
}

扩展解决方案(由Shubham Khatri建议)用于React钩子(16.8起):

package.json (always worth updating to latest packages)

{
     ...

     "react": "^16.12.0",
     "react-router-dom": "^5.1.2",

     ...
}

使用历史推送传递参数:

import { useHistory } from "react-router-dom";

const FirstPage = props => {
    let history = useHistory();

    const someEventHandler = event => {
       history.push({
           pathname: '/secondpage',
           search: '?query=abc',
           state: { detail: 'some_value' }
       });
    };

};

export default FirstPage;


从'react-router-dom'中使用useLocation访问传递的参数:

import { useEffect } from "react";
import { useLocation } from "react-router-dom";

const SecondPage = props => {
    const location = useLocation();

    useEffect(() => {
       console.log(location.pathname); // result: '/secondpage'
       console.log(location.search); // result: '?query=abc'
       console.log(location.state.detail); // result: 'some_value'
    }, [location]);

};

要使用React 16.8(带hooks)功能组件,您可以使用这种方式 我们发送PhoneNumber到Next Page Login.js

    import { useHistory } from 'react-router-dom';
    const history = useHistory();
        const handleOtpVerify=(phoneNumber)=>
          {
               history.push("/OtpVerifiy",{mobNo:phoneNumber})
          } 

<button onClick={handleOtpVerify}> Submit </button>

OtpVerify.js

    import  useLocation  from 'react-router-dom';
    const [phoneNumber, setphoneNumber] = useState("")
        useEffect(() => {
                setphoneNumber(location.state.mobNo)
            }, [location]);
    return (
    <p>We have sent Verification Code to your</p>
    <h1>{phoneNumber}</h1>
    )

React路由器dom版本6.2.1 useNavigate()已弃用

import { useNavigate } from "react-router-dom";

 const navigate = useNavigate()
 
 onClick={() => { navigate('/OtpVerifiy',{mobNo:phoneNumber}) }}
