Angular6 类型'；上不存在属性分派；可观察<；任何>'；在angular 6中使用redux时出现问题

我正在尝试用angular 6做简单的redux应用程序

减速器.ts

import { login,logout } from '../actions/actions';
export interface appReducer {
    login:boolean,
    user:String
}
const initialstate:appReducer={
    login:false,
    user:'guest'
}
export function reducer(state=initialstate,action):appReducer {
    switch(action.type) {
        case login:
            return {...state,login:true,user:action.payload}
        case logout:
            return {...state,login:false,user:action.payload}   
    }
    return state;
}

export const login="LOGIN";
export const logout="LOGOUT"

import { reducer,appReducer } from './reducer';
import { ActionReducerMap }  from '@ngrx/store';
interface appState {
    appReducer:appReducer;
}
export const reducers:ActionReducerMap<appState>= {
    appReducer:reducer
}

import { Injectable } from '@angular/core';
import { HttpClient,HttpHeaders } from '@angular/common/http';
import { Observable } from 'rxjs';
import { Store }  from '@ngrx/store';
export class RecordsService {
  getLogin:boolean=false;
  constructor(private http:HttpClient,private store:Store<any>) { 
    this.recordFunc();
  }
     getState() {
        return this.store.select('appReducer');
      }
      updateState(action) {
        if(action.login==true) {
            return this.store.select('appReducer').dispatch({
                type:'LOGIN',
                payload:action.uname
            })
        }
        else {
            return this.store.select('appReducer').dispatch({
                type:'LOGOUT',
                payload:action.uname
            })
        }   
      }
}

动作。ts

import { login,logout } from '../actions/actions';
export interface appReducer {
    login:boolean,
    user:String
}
const initialstate:appReducer={
    login:false,
    user:'guest'
}
export function reducer(state=initialstate,action):appReducer {
    switch(action.type) {
        case login:
            return {...state,login:true,user:action.payload}
        case logout:
            return {...state,login:false,user:action.payload}   
    }
    return state;
}

export const login="LOGIN";
export const logout="LOGOUT"

import { reducer,appReducer } from './reducer';
import { ActionReducerMap }  from '@ngrx/store';
interface appState {
    appReducer:appReducer;
}
export const reducers:ActionReducerMap<appState>= {
    appReducer:reducer
}

import { Injectable } from '@angular/core';
import { HttpClient,HttpHeaders } from '@angular/common/http';
import { Observable } from 'rxjs';
import { Store }  from '@ngrx/store';
export class RecordsService {
  getLogin:boolean=false;
  constructor(private http:HttpClient,private store:Store<any>) { 
    this.recordFunc();
  }
     getState() {
        return this.store.select('appReducer');
      }
      updateState(action) {
        if(action.login==true) {
            return this.store.select('appReducer').dispatch({
                type:'LOGIN',
                payload:action.uname
            })
        }
        else {
            return this.store.select('appReducer').dispatch({
                type:'LOGOUT',
                payload:action.uname
            })
        }   
      }
}

index.ts

import { login,logout } from '../actions/actions';
export interface appReducer {
    login:boolean,
    user:String
}
const initialstate:appReducer={
    login:false,
    user:'guest'
}
export function reducer(state=initialstate,action):appReducer {
    switch(action.type) {
        case login:
            return {...state,login:true,user:action.payload}
        case logout:
            return {...state,login:false,user:action.payload}   
    }
    return state;
}

export const login="LOGIN";
export const logout="LOGOUT"

import { reducer,appReducer } from './reducer';
import { ActionReducerMap }  from '@ngrx/store';
interface appState {
    appReducer:appReducer;
}
export const reducers:ActionReducerMap<appState>= {
    appReducer:reducer
}

import { Injectable } from '@angular/core';
import { HttpClient,HttpHeaders } from '@angular/common/http';
import { Observable } from 'rxjs';
import { Store }  from '@ngrx/store';
export class RecordsService {
  getLogin:boolean=false;
  constructor(private http:HttpClient,private store:Store<any>) { 
    this.recordFunc();
  }
     getState() {
        return this.store.select('appReducer');
      }
      updateState(action) {
        if(action.login==true) {
            return this.store.select('appReducer').dispatch({
                type:'LOGIN',
                payload:action.uname
            })
        }
        else {
            return this.store.select('appReducer').dispatch({
                type:'LOGOUT',
                payload:action.uname
            })
        }   
      }
}

从“/reducer”导入{reducer，appReducer}；
从'@ngrx/store'导入{ActionReducerMap}；
接口应用状态{
评价者：评价者；
}
导出常量缩减器：ActionReducerMap={
评价者：减速机
}

记录.服务.ts

import { login,logout } from '../actions/actions';
export interface appReducer {
    login:boolean,
    user:String
}
const initialstate:appReducer={
    login:false,
    user:'guest'
}
export function reducer(state=initialstate,action):appReducer {
    switch(action.type) {
        case login:
            return {...state,login:true,user:action.payload}
        case logout:
            return {...state,login:false,user:action.payload}   
    }
    return state;
}

export const login="LOGIN";
export const logout="LOGOUT"

import { reducer,appReducer } from './reducer';
import { ActionReducerMap }  from '@ngrx/store';
interface appState {
    appReducer:appReducer;
}
export const reducers:ActionReducerMap<appState>= {
    appReducer:reducer
}

import { Injectable } from '@angular/core';
import { HttpClient,HttpHeaders } from '@angular/common/http';
import { Observable } from 'rxjs';
import { Store }  from '@ngrx/store';
export class RecordsService {
  getLogin:boolean=false;
  constructor(private http:HttpClient,private store:Store<any>) { 
    this.recordFunc();
  }
     getState() {
        return this.store.select('appReducer');
      }
      updateState(action) {
        if(action.login==true) {
            return this.store.select('appReducer').dispatch({
                type:'LOGIN',
                payload:action.uname
            })
        }
        else {
            return this.store.select('appReducer').dispatch({
                type:'LOGOUT',
                payload:action.uname
            })
        }   
      }
}

从'@angular/core'导入{Injectable}；
从'@angular/common/http'导入{HttpClient，HttpHeaders}；
从“rxjs”导入{Observable}；
从'@ngrx/Store'导入{Store}；
导出类记录服务{
getLogin:boolean=false；
构造函数（私有http:HttpClient，私有存储：存储）{
this.recordFunc（）；
}
getState（）{
返回此.store.select（'appReducer'）；
}
不动产（行动）{
if（action.login==true）{
返回此.store.select（'appReducer'）。分派({
类型：'LOGIN'，
有效载荷：action.uname
})
}
否则{
返回此.store.select（'appReducer'）。分派({
类型：'LOGOUT'，
有效载荷：action.uname
})
}   
}
}

在上面的代码中，我创建了reducer并成功地在store模块中注册。然后我在我的服务（records.service.ts）文件中导入了该存储。通过订阅我的getState（），我获得了我的当前状态，但当我调用updateState（）时要分派更新状态的操作，它会在我的终端中显示以下错误，并更新我的状态

ERROR in src/app/records.service.ts(69,44): error TS2339: Property 'dispatch' does not exist on type 'Observable<any>'.
src/app/records.service.ts(75,42): error TS2339: Property 'dispatch' does not exist on type 'Observable<any>'.

src/app/records.service.ts（69,44）中的错误：错误TS2339:类型“Observable”上不存在属性“dispatch”。
src/app/records.service.ts（75,42）：错误TS2339:类型“Observable”上不存在属性“dispatch”。

我面临同样的问题，并找到了一个快速解决方案

不要使用

store.select（'appReducer'）.dispatch

只需使用

store.dispatch

像这样使用.store.dispatch（{type:'LOGOUT'，payload:action.uname}）
