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');
          });

For the earlier versions: history.push('/[pathToSomeWhere]', yourData); And get the data in the related component just like below: this.props.location.state // it is equal to yourData For the newer versions the above way works well but there is a new way: history.push({ pathname: '/[pathToSomeWhere]', state: yourData, }); And get the data in the related component just like below: Class Component this.props.location.state; // it is equal to yourData Function Component const location = useLocation(); location.state; // it is equal to yourData


有时需要使用Link或NavLink组件,而不是使用历史记录。推动作用。你可以用下面的like:

<Link
  to={{
    pathname: '/[pathToSomeWhere]',
    state: yourData
  }}
> 
  ...
</Link>

提示:状态键名称应在最新版本中使用。

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>
  );
}

如果你需要传递URL参数

Tyler McGinnis在他的网站上有一个很好的解释,链接到这个帖子

下面是代码示例:

关于历史。将组件: this.props.history.push(“/ home: $ {this.state.userID}”) 在路由器组件上定义路由: <路由路径='/home:myKey'组件={home} /> Home组件:

componentDidMount(){
    const { myKey } = this.props.match.params
    console.log(myKey )
}

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]);

};

首先,你不需要var r = this;就像if语句中引用回调本身的上下文一样,因为你使用的是箭头函数,所以它引用的是React组件上下文。

根据文件:

history objects typically have the following properties and methods: length - (number) The number of entries in the history stack action - (string) The current action (PUSH, REPLACE, or POP) location - (object) The current location. May have the following properties: pathname - (string) The path of the URL search - (string) The URL query string hash - (string) The URL hash fragment state - (string) location-specific state that was provided to e.g. push(path, state) when this location was pushed onto the stack. Only available in browser and memory history. push(path, [state]) - (function) Pushes a new entry onto the history stack replace(path, [state]) - (function) Replaces the current entry on the history stack go(n) - (function) Moves the pointer in the history stack by n entries goBack() - (function) Equivalent to go(-1) goForward() - (function) Equivalent to go(1) block(prompt) - (function) Prevents navigation

在导航时,你可以将道具传递给历史对象,比如

this.props.history.push({
  pathname: '/template',
  search: '?query=abc',
  state: { detail: response.data }
})

或类似的链接组件或重定向组件

<Link to={{
      pathname: '/template',
      search: '?query=abc',
      state: { detail: response.data }
    }}> My Link </Link>

然后在使用/template route渲染的组件中,你可以访问传递的道具

this.props.location.state.detail

还要记住,当使用来自道具的历史记录或位置对象时,您需要将组件与throuter连接起来。

根据文档:

withRouter 您可以访问历史对象的属性和最接近的属性 <路由>的匹配通过withRouter高阶组件。withRouter 将重新渲染它的组件时,每次路由改变 与<Route>渲染道具相同:{match, location, history}。

您可以使用location将状态发送到其他组件,就像这样

在源组件中

this.props.history.push(pathComponent, sendState);

pathComponent是接收状态的目标组件

在目标组件中 如果您使用类组件,您可以像这样接收状态

Javascript版本

constructor(props) {
  this.state = this.props.location.state
}

打印稿版本

constructor(props: {}) {
  const receiveState = this.props.location.state as StateType // you must parse into your state interface or type
  this.state = receiveState
}

奖金

如果你想重置收到的状态。使用历史记录替换位置,像这样

this.props.history({pathName: currentPath, state: resetState})

“currentPath”为目标组件路径 resetState是你想要的新值状态
