在React中有一些让我发疯的事情,我需要你的帮助。基本上,当用户点击“我的个人资料”时,我想重定向到用户的个人资料。为此,我使用以下代码段
viewProfile = () => {
console.log('My USER ID: ', this.props.userId);
this.props.history.push(`/profile/${this.props.userId}`);
}
这应该有效。但是,虽然在单击“我的个人资料”时URL正在更改为正确的URL,但该页面未显示。它只是保留旧页面。
谷歌搜索了一段时间后,我知道这与redux有关...但是,我找不到解决方案。 (this.props.userId来自一个Layout组件,后者从redux商店获取它)
这是我的代码:
// React
import React, { Component } from 'react';
import { withRouter } from 'react-router-dom';
// Redux
import { connect } from 'react-redux';
import * as actions from '../../../store/actions/';
// Containers and Components
...// more imports
const styles = // styles
class NavBar extends Component {
handleAuthentication = () => {
if (this.props.isAuthenticated) {
this.props.history.push('/logout');
} else {
this.props.history.push('/login');
}
};
viewProfile = () => {
console.log('My USER ID: ', this.props.userId);
this.props.history.push(`/profile/${this.props.userId}`);
};
render() {
let buttons = (
<Auxillary>
{this.props.isAuthenticated ? (
<RaisedButton
label="MY PROFILE"
primary={true}
style={styles.button}
onClick={this.viewProfile} // THIS IS THE METHOD
/>
) : null}
<RaisedButton
backgroundColor={grey900}
label={this.props.isAuthenticated ? 'LOGOUT' : 'LOGIN'}
labelColor={grey50}
style={styles.button}
onClick={this.handleAuthentication}
/>
</Auxillary>
);
let itemSelectField = null;
if (this.props.location.pathname === '/items') {
itemSelectField = (
<ItemSelectField
onSelectTags={tags => this.props.filterItemsByTagName(tags)}
/>
);
}
let bar = null;
if (
this.props.location.pathname !== '/login' &&
this.props.location.pathname !== '/register'
) {
bar = (
<AppBar
style={styles.appBar}
title={itemSelectField}
iconElementLeft={
<img style={styles.logoHeight} src={Logo} alt="logo" />
}
iconElementRight={buttons}
/>
);
}
return <Auxillary>{bar}</Auxillary>;
}
}
const mapDispatchToProps = dispatch => {
return {
filterItemsByTagName: selectedTags =>
dispatch(actions.filterItemsByTagName(selectedTags))
};
};
export default withRouter(connect(null, mapDispatchToProps)(NavBar));

您需要整合react-router-redux
。
看起来更新的状态没有反映在容器中,因为redux做了浅比较以检查组件是否需要更新。
import {Router} from 'react-router-dom';
import { ConnectedRouter, routerReducer, routerMiddleware } from 'react-router-redux';
import createHistory from 'history/createBrowserHistory';
const history = createHistory()
const middleware = routerMiddleware(history)
const rootReducer = combineReducers({
router: routerReducer,
//other reducers
});
const store = createStore(rootReducer,applyMiddleware(middleware));
<Provider store={store}>
<ConnectedRouter>
//routes
</ConnectedRouter>
</Provider>
此外,在reducer中,添加此代码段。
let updatedStore = JSON.parse(JSON.stringify(state));

我认为使用<BrowserRouter>
与您有关。它创建自己的历史记录实例,并监听其中的更改。因此,不同的实例将更改网址,但不会更新<BrowserRouter>
。相反,您可以使用ConnectedRouter
并将历史记录实例作为
import createHistory from 'history/createBrowserHistory';
...
const history = createHistory();
...
<ConnectedRouter history={history}>
...
</ConnectedRouter>
