With Regular Expression maybe this solution is easier for you:

  var oldURL = 'http://my.site/?code=74e30ef2-109c-4b75-b8d6-89bdce1aa860'
  var newURL = /(http(s?).+)(\?.+)/.exec(oldDomain)[1] + 'homepage'

You can use newURL in your project.

Try this one (hardcode way)

import { push } from 'react-router-redux'

...
const url = `${window.location.origin}/homepage`;
dispatch(push(url));

Or this one

history.location.pathname =`${window.location.origin}/homepage`;

Those methods are not a good practice at all but those work (the second one for sure)

Per the following links, I git cloned this and ran npm install in both the main directory and the example basic directory, and ran npm start to get a working example.

Code to remove query params (close to the bottom) and validate that they're removed:

import { createStore, combineReducers, applyMiddleware } from 'redux'
import { browserHistory } from 'react-router'
import { syncHistoryWithStore, routerReducer, routerMiddleware, push } from 'react-router-redux'
import * as reducers from './reducers'

const reducer = combineReducers({
  ...reducers,
  routing: routerReducer
})

const middleware = routerMiddleware(browserHistory)

const store = createStore(
  reducer,
  applyMiddleware(middleware)
)
const history = syncHistoryWithStore(browserHistory, store)

// Dispatch from anywhere like normal.
store.dispatch(push("/?test=ok"));
// store2.dispatch(push(history.createHref("/")));
var count = 0;

history.listen(location => {
    console.log(location);
    if (count > 1) { return; }
    count++;
    store.dispatch(push({ pathname:'/', search: '' })); // Drops the params
});

Check console and you'll see the query params (search) field is empty

See my router section

 <div>
                <MainHeader />
                <Switch>
                    <Route exact path='/:pickupLocationName/:pickupDate/:pickupTime/:returnDate/:returnTime' render={(props) => <Quote  {...props} />} />
                    <Route path='/BookerInitial/:user/:id' component={BookerInitial} />
                    <Route path='/VehicleList' component={VehicleList} />
                    <Route path='/AdditionalCoverages' component={AdditionalCoverages} />
                    <Route path='/BookingDetails' component={BookingDetails} />
                    <Route path='/RenterInfo' component={RenterInfo} />
                </Switch>
                <Footer/>
            </div>

There is next buton in BookerInitial page

<button className="submit btn-skew-r btn-effect" id="nextBtn" style={{ backgroundColor: "#da1c36" }} onClick={this.handleSubmit}  >Next</button>

Submit button method

 handleSubmit = () => {
      this.props.history.push('./VehicleList');

    }

I also faced this problem. finally i found the solution i changed as this.props.history.push('/VehicleList'); from this.props.history.push('./VehicleList'); above you can see the dot(.) is the issue with my code. so no need to remove parameter in URL by code. thank you
