我真的不知道如何用正则表达式来约束参数。
如何区分这两种路线?
<Router>
<Route path="/:alpha_index" component={Child1} />
<Route path="/:numeric_index" component={Child2} />
</Router>
并阻止“ / 123”触发第一条路线?
React-router v4现在允许您使用正则表达式来匹配参数-https: //reacttraining.com/react-router/web/api/Route/path-string
const NumberRoute = () => <div>Number Route</div>;
const StringRoute = () => <div>String Route</div>;
<Router>
<Switch>
<Route exact path="/foo/:id(\\d+)" component={NumberRoute}/>
<Route exact path="/foo/:path(\\w+)" component={StringRoute}/>
</Switch>
</Router>
