如何在 react-router v4 中使用 history.push/Link/Redirect 传递参数? [英] How to pass params with history.push/Link/Redirect in react-router v4?

问题描述

我们如何在 React-Router v4 中使用 this.props.history.push('/page') 传递参数?

How can we pass parameter with this.props.history.push('/page') in React-Router v4?

.then(response => {
       var r = this;
        if (response.status >= 200 && response.status < 300) {
             r.props.history.push('/template');
          });

推荐答案

首先，你不需要做 var r = this; as this in if statement指向回调本身的上下文，因为您使用的是箭头函数，因此引用了 React 组件上下文.

First of all, you need not do var r = this; as this in if statement refers to the context of the callback itself which since you are using arrow function refers to the React component context.

history 对象通常具有以下属性和方法:

history objects typically have the following properties and methods:

• length - (number) 历史堆栈中的条目数
• action - (字符串)当前操作(PUSH、REPLACE 或 POP)

• location - (object) 当前位置.可能具有以下属性:

• length - (number) The number of entries in the history stack
• action - (string) The current action (PUSH, REPLACE, or POP)

• location - (object) The current location. May have the following properties:

• pathname - (string) URL 的路径
• search - (string) URL 查询字符串
• hash - (字符串)URL 哈希片段
• state -(字符串)提供给例如的特定于位置的状态push(path, state) 当这个位置被推到堆.仅在浏览器和内存历史记录中可用.

因此，在导航时，您可以将道具传递给历史对象，例如

So while navigating you can pass props to the history object like

this.props.history.push({
  pathname: '/template',
  search: '?query=abc',
  state: { detail: response.data }
})

或类似的对于 Link 组件或 Redirect 组件

or similarly for the Link component or the Redirect component

<Link to={{
      pathname: '/template',
      search: '?query=abc',
      state: { detail: response.data }
    }}> My Link </Link>

然后在使用 /template 路由渲染的组件中，您可以访问像

and then in the component which is rendered with /template route, you can access the props passed like

this.props.location.state.detail

还要记住，当使用 props 中的 history 或 location 对象时，您需要将组件与 withRouter 连接起来.

Also keep in mind that, when using history or location objects from props you need to connect the component with withRouter.

withRouter

您可以访问历史对象的属性和最近的's 通过 withRouter 高阶组件匹配.withRouter每次路由随着与 渲染相同的 props props: { match, location, history }.

You can get access to the history object’s properties and the closest <Route>'s match via the withRouter higher-order component. withRouter will re-render its component every time the route changes with the same props as <Route> render props: { match, location, history }.
