if you are using React Router and your component is rendered by a Routelike below for example:
如果您使用的是 React Router 并且您的组件是由Route以下示例呈现的：
<Route exact path='/' component={HomeComponent}/>
that component will automatically receive three objects from Routenamed history, locationand matchrespectively. by that you can find what you asked under location.pathname. more info here
该组件可以自动从三个对象Route命名history，location并match分别。通过它，您可以找到您在 下询问的内容location.pathname。更多信息在这里
if you still using react router and your component is not been rendered with Route, you need to use withRouter, which is a HOC and will give you history, locationand matchas props to your component. more info here
如果您仍在使用 react 路由器并且您的组件未使用 进行渲染Route，则需要使用withRouter，这是一个 HOC 并将为您提供history,location并match作为组件的道具。更多信息在这里
if you are not using react router you gonna need to use window.location.pathnameor window.location.hrefor only location.pathname
如果你没有使用你的路由器会作出反应需要使用window.location.pathname或window.location.href或只location.pathname
回答by Sakhi Mansoor
If you are using react router:
如果您使用的是反应路由器：
const currentRoute= this.props.location.pathname
else you can get this like:
否则你可以得到这样的：
const currentRoute= window.location.pathname
href will give you complete url.
href 会给你完整的网址。
