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"
}

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。

下面是使用React Router重定向到外部链接的一行代码:

<Route path='/privacy-policy' component={() => {
    window.location.href = 'https://example.com/1234';
    return null;
}}/>

它使用React纯组件概念,将组件代码减少为一个函数,而不是渲染任何东西,将浏览器重定向到外部URL。

它在React Router 3和4上都可以工作。

我很幸运:

<Route
    path="/example"
    component={() => {
        global.window && (global.window.location.href = 'https://example.com');
        return null;
    }}
/>

不需要使用React Router中的<Link />组件。

如果你想去外部链接使用锚标签。

<a target="_blank" href="https://meetflo.zendesk.com/hc/en-us/articles/230425728-Privacy-Policies">Policies</a>

利用这里的一些信息,我提出了以下组件,您可以在路由声明中使用它。它与React Router v4兼容。

它使用的是TypeScript,但转换为原生JavaScript应该相当简单:

interface Props {
  exact?: boolean;
  link: string;
  path: string;
  sensitive?: boolean;
  strict?: boolean;
}

const ExternalRedirect: React.FC<Props> = (props: Props) => {
  const { link, ...routeProps } = props;

  return (
    <Route
      {...routeProps}
      render={() => {
        window.location.replace(props.link);
        return null;
      }}
    />
  );
};

与…一起使用:

<ExternalRedirect
  exact={true}
  path={'/privacy-policy'}
  link={'https://example.zendesk.com/hc/en-us/articles/123456789-Privacy-Policies'}
/>
