问题描述
如何在 reducer 中使用 redux-router 获取当前路径和查询当前位置.我可以使用 mapStateToProps 在组件内轻松获取路径名,但我想访问 reducer 中的当前路径.我使用的是 redux-router 1.0.0-beta7,react-router 1.0.3.
How would i get the current path and query of the current location with redux-router in reducer. I am able to get the pathname easily inside the component with mapStateToProps, but i want to access the current path in reducer. I am using redux-router 1.0.0-beta7, react-router 1.0.3.
推荐答案
1.way - 将 pathname 和特定的 action 传递到 >redux-thunk 和 getState()
1.way - pass pathname with particular action through redux-thunk and getState()
const someAction = data =>(dispatch,getState)=>{
dispatch({
type:'SOME_ACTION',
pathname:getState().router.pathname
})
}
2.way - 编写中间件并在每个动作中传递路径名
2.way - write middleware and pass pathname with every action
///write middleware
export const attachPathNameToAction = store => next => action=>{
action.pathname = store.getState().router.pathname //<-----passing pathname
next(action)
};
///then in reducer you allways can get pathname
case 'SOME_ACTION':
let pathname = action.pathname \\ <-------------
return {...state, action.data}
3.way - 从组件的 this.props.location.pathname 传递路径名
3.way - pass pathname from component's this.props.location.pathname
//in component
let {pathname}= this.props.location;
this.props.someAction(data, pathname);
//workflow: component -> action -> reducer
