Reactjs ReactRedux 在应用程序加载初始化时调度操作

Update 2020:

export default () => next => action => {
  const result = next(action);
  const { type, payload } = result;

  if (type.endsWith('Failure')) {
    if (payload.status === 401) {
      removeToken();

      window.location.replace('/login');
    }
  }

  return result;
};

Update 2018:这个答案适用于React Router 3

我用onEnter个props 解决了这个问题.下面是代码的样子:

// this function is called only once, before application initially starts to render react-route and any of its related DOM elements
// it can be used to add init config settings to the application
function onAppInit(dispatch) {
  return (nextState, replace, callback) => {
    dispatch(performTokenRequest())
      .then(() => {
        // callback is like a "next" function, app initialization is stopped until it is called.
        callback();
      });
  };
}

const App = () => (
  <Provider store={store}>
    <IntlProvider locale={language} messages={messages}>
      <div>
        <Router history={history}>
          <Route path="/" component={MainLayout} onEnter={onAppInit(store.dispatch)}>
            <IndexRoute component={HomePage} />
            <Route path="about" component={AboutPage} />
          </Route>
        </Router>
      </div>
    </IntlProvider>
  </Provider>
);
