How to access current location in reducer (redux-r

问题:

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.

回答1:

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 - 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 - 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
