如何访问reducer (redux-router)中的当前位置？

Question

如何在reducer中使用redux-router获取当前路径和当前位置的查询。我可以使用mapStateToProps很容易地在组件中获取路径名，但我想访问reducer中的当前路径。我使用redux-router 1.0.0-beta7，react-router 1.0.3。

1.way -通过和getState()传递带有特定操作的路径名

const someAction = data =>(dispatch,getState)=>{
   dispatch({
      type:'SOME_ACTION',
      pathname:getState().router.pathname
   })
}

2.way -编写中间件，并为每个操作传递路径名

///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

//in component 
let {pathname}= this.props.location;
this.props.someAction(data, pathname);

//workflow:  component -> action -> reducer
