1、props.match.params

import React from 'react';import { RouteConfigComponentProps } from 'react-router-config';interface IParam {  id?: string;}interface IProps extends RouteConfigComponentProps      {}const Main = (props: IProps) => {  const { id } = props.match.params;  console.log('参数:', id)  return (                 123123         )}export default Main

这里需要指定路由参数的类型,不然Param类型默认是{}

export interface RouteConfigComponentProps      extends RouteComponentProps        {    route?: RouteConfig;}export interface RouteComponentProps<    Params extends { [K in keyof Params]?: string } = {},    C extends StaticContext = StaticContext,    S = H.LocationState> {    history: H.History    ;    location: H.Location;    match: match      ; staticContext?: C;}export interface match { params: Params; isExact: boolean; path: string; url: string;}

2、useParams

使用react-router-dom提供的hooks函数useParams,useParams直接返回路由参数对象

export function useParams         (): Params;

同样,useParams使用时需要指定Params类型

import React from 'react';import { RouteConfigComponentProps } from 'react-router-config';import { useParams } from 'react-router-dom';interface IParam {  id?: string;}interface IProps extends RouteConfigComponentProps<{}> {}const Main = (props: IProps) => {  const { id } = useParams         ();  console.log('参数:', id)  return (                     123123           )}export default Main

3、props.location.search

export interface History          {    length: number;    action: Action;    location: Location           ;    push(path: Path, state?: HistoryLocationState): void;    push(location: LocationDescriptor      ): void; replace(path: Path, state?: HistoryLocationState): void; replace(location: LocationDescriptor ): void; go(n: number): void; goBack(): void; goForward(): void; block(prompt?: boolean | string | TransitionPromptHook ): UnregisterCallback; listen(listener: LocationListener ): UnregisterCallback; createHref(location: LocationDescriptorObject ): Href;}

当页面不是用过路由传参(/about/:id),而是通过props.history.push({pathname: 'xxx', search: 'xxx'})跳转携带参数,这种场景下该如何获取参数呢?

A页面 跳转 B页面

import qs from 'query-string';interface IProps extends RouteConfigComponentProps<{}> {}const A = (props: IProps) => {        const gotoPage = () => {        props.history.push({          pathname: '/B',           search: qs.stringify({id: 123123})        })    }        return (        goto B page    )       }export default A;

B页面接收参数

import qs from 'query-string';interface IProps extends RouteConfigComponentProps<{}> {}const B = (props: IProps) => {    const { id } = qs.parse(props.location.search);    console.log('参数:', id)    return (                           123123                )}export default B;
