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');
});

if (response.status >= 200 && response.status < 300) {
r.props.history.push('/template');
});
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}。
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
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。
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 )
}
你可以用,
this.props.history。Push ("/template",{…响应}) 或 this.props.history。推送("/template", {response: response})
然后,您可以通过以下代码访问/template组件中的解析数据:
Const state = this.props.location.state

要使用React 16.8+(带hooks),您可以使用这种方式
import React from 'react';
import { useHistory } from 'react-router-dom';
export default function SomeFunctionalComponent() {
let history = useHistory(); // should be called inside react component
const handleClickButton = () => {
"funcionAPICALL"
.then(response => {
if (response.status >= 200 && response.status < 300) {
history.push('/template');
});
}
return ( <div> Some component stuff
<p>To make API POST request and redirect to "/template" click a button API CALL</p>
<button onClick={handleClickButton}>API CALL<button>
</div>)
}
来源这里阅读更多https://reacttraining.com/react-router/web/example/auth-workflow
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]);
};
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>
);
}
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}`,
});
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
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
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}) }}
