由于我在React应用程序中使用React路由器来处理我的路由,我很好奇是否有一种方法可以重定向到外部资源。
比如有人打人:
example.com/privacy-policy
我希望它重定向到:
example.zendesk.com/hc/en-us/articles/123456789-Privacy-Policies
我发现在我的index.html加载中,避免用纯JavaScript编写它完全没有任何帮助:
if (window.location.path === "privacy-policy"){
window.location = "example.zendesk.com/hc/en-us/articles/123456789-Privacy-Policies"
}
最简单的解决方案是使用渲染函数并更改window.location。
<Route path="/goToGoogle"
render={() => window.location = "https://www.google.com"} />
如果你想要一个小型的可重用组件,你可以像这样提取它:
const ExternalRedirect = ({ to, ...routeProps }) => {
return <Route {...routeProps} render={() => window.location = to} />;
};
然后像这样使用它(例如在你的路由器开关中):
<Switch>
...
<ExternalRedirect exact path="/goToGoogle" to="https://www.google.com" />
</Switch>
它不需要请求React路由器。这个操作可以在本地完成,由浏览器提供。
只需使用window.location。
React挂钩
const RedirectPage = () => {
React.useEffect(() => {
window.location.replace('https://www.google.com')
}, [])
}
使用React类组件
class RedirectPage extends React.Component {
componentDidMount(){
window.location.replace('https://www.google.com')
}
}
另外,如果你想在一个新标签中打开它:
window.open('https://www.google.com', '_blank');
用react-router的Link组件就可以做到。在“to”道具中,您可以指定3种类型的数据:
a string: A string representation of the Link location, created by concatenating the location’s pathname, search, and hash properties.
an object: An object that can have any of the following properties:
pathname: A string representing the path to link to.
search: A string representation of query parameters.
hash: A hash to put in the URL, e.g. #a-hash.
state: State to persist to the location.
a function: A function to which current location is passed as an argument and which should return location representation as a string or as an object
对于你的例子(外部链接):
https://example.zendesk.com/hc/en-us/articles/123456789-Privacy-Policies
您可以执行以下操作:
<Link to={{ pathname: "https://example.zendesk.com/hc/en-us/articles/123456789-Privacy-Policies" }} target="_blank" />
您还可以传递您想要的道具,如标题,id, className等。
