我正在尝试做一些简单的事情 - 在一些实体保存后(使用http请求)我想导航回列表路由.问题是:如何订阅成功动作(或者可能是减速器或效果？)

这是我的行为代码:

static SAVE_POST = '[POST] Save POST';
savePOST(Post): Action {
    return {
        type: PostActions.SAVE_POST,
        payload: Post
    };
}

static SAVE_POST_SUCCESS = '[POST] Save POST Success';
savePOSTSuccess(Post): Action {
    console.log('action: savePostSuccess')
    return {
        type: PostActions.SAVE_POST_SUCCESS,
        payload:Post
    };
}

我正在使用效果:

   @Effect() savePost$ = this.update$
    .ofType(PostActions.SAVE_POST)
    .map(action => action.payload)
    .switchMap(post => this.svc.savePost(post))
    .map(post => this.postActions.savePOSTSuccess(post));

减速器:

const initialState: PostListState = [];

export default function (state = initialState, action: Action): PostListState {
    switch (action.type) {
        case PostActions.LOAD_POST_SUCCESS: {
            return action.payload;
        } …
