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

没有必要与throuter一起使用。这对我来说很管用:

在父页面中，

<BrowserRouter>
   <Switch>
        <Route path="/routeA" render={(props)=> (
          <ComponentA {...props} propDummy={50} />
        )} />

        <Route path="/routeB" render={(props)=> (
          <ComponentB {...props} propWhatever={100} />
          )} /> 
      </Switch>
</BrowserRouter>

然后在ComponentA或ComponentB中进行访问

this.props.history

对象，包括this.props.history.push方法。

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

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 )
}

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');

有关URLSearchParams的更多信息，请查看此链接 URLSearchParams

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。
