我只是想通过onClick (event)
将我的connect()
、LoginPage (component)
Redux Store
和dispatch
。当我console.log(this.props)
时,我的调度处理程序login()
不在组件的道具中。

问题:为什么我的Redux Store
不是connection
或dispatching
?
登录页面:
import React, { Component} from 'react';
import { connect } from 'react-redux';
export class LoginPage extends Component<any> {
render(){
console.log('props doesnt have contain - login(): ', this.props)
return (<button onClick={ () => '' }>Login</button>)
}
}
const mapProps = state => ({ user: state.user })
const dispatchProps = (dispatch) => {
return {
login: () => dispatch({ type: 'USER_LOGGED_IN', payload: true})
}
}
export default connect(mapProps,dispatchProps)(LoginPage)
Redux配置:
import { IStore, IUser } from '@interfaces';
import { createStore, combineReducers } from 'redux';
import ReduxPromise from 'redux-promise';
// reducers
import userReducer from './user.reducer';
// define the intial global store state
const initialState:IStore = {
user: {
isAuthenticated: false
}
}
const appReducer = combineReducers({user: userReducer})
export default createStore(appReducer,initialState);
用户缩减器:
// initial state
const initalState:IUser = {
isAuthenticated: false
}
// reducer
const userReducer = (state:IUser = initalState, { type, payload}: IPayload): IUser => {
console.log('user reducer start', state)
switch (type) {
case 'USER_LOGGED_IN':
state = { ...state, isAuthenticated: payload }
break;
default:
return state;
}
return state;
};
export default userReducer;
根页面:
import React from 'react';
import { render } from 'react-dom';
import { Provider } from 'react-redux';
// styles
import './index.scss';
// pages
import { App } from '@pages';
// store
import store from './core/store/store';
render(
<Provider store={store}>
<App/>
</Provider>, document.getElementById('app')
);
我在git存储库上检查了您的代码。我发现你正在导出命名的导出
export class LoginPage
和默认导出
export default connect(mapProps,dispatchProps)(LoginPage)
但当你访问它时,你是以的身份访问它
import { /*Other components*/ , LoginPage } from '@pages'
因此,它实际上是在获取未连接到存储的已命名导出组件。
我建议你作为进口
import LoginPage , { /*Other components*/ } from '@pages'
这可能会解决你的问题。
const mapProps = state => { return {user: state.user} }
const dispatchProps = (dispatch) => {
return {
login: () => dispatch({ type: 'USER_LOGGED_IN', payload: true})
}
}
export default connect(mapProps,dispatchProps)(LoginPage)
更新时间:请检查Redux调度
try:
import React, { Component} from 'react';
import { connect } from 'react-redux';
export class LoginPage extends Component<any> {
render(){
console.log('props doesnt contain - login(): ', this.props)
return (
<button onClick={ this.props.login }>Login</button>
)
}
}
const mapProps = state => ({ user: state.user })
const dispatchProps = (dispatch) => ({
login: () => dispatch({ type: 'USER_LOGGED_IN', payload: true})
})
export default connect(mapProps,dispatchProps)(LoginPage)
