【问题描述】:
自从我开始使用 react/redux 以来,我第一次使用 react-router-dom 应用程序,但我在使用 Redirect 组件时遇到了问题。
我想在身份验证成功时触发Redirect,但在身份验证后它不会重定向到我想要的页面。
index.js
import { BrowserRouter as Router, Route } from 'react-router-dom';
import { createStore, applyMiddleware } from 'redux';
import ReduxThunk from 'redux-thunk';
import App from './components/app';
import Page1 from './containers/page1';
import Signin from './containers/auth/signin';
import Reducers from './reducers';
const createStoreWithMiddleware = applyMiddleware(ReduxThunk)(createStore);
const store = createStoreWithMiddleware(Reducers);
ReactDOM.render(
<Provider store={store}>
<Router>
<div>
<Route path="/" component={App}/>
<Route path="/" component={Signin}/>
<Route path="/signin" component={Signin}/>
<Route path="/page1" component={Page1}/>
</div>
</Router>
</Provider>
, document.querySelector('.container'));
signin.js
import { BrowserRouter as Route, Redirect } from 'react-router-dom';
import { userSignin } from '../../actions/index';
class Signin extends Component {
constructor(props) {
super(props);
this.state = { username: '', password: '' };
this.handleSubmit = this.handleSubmit.bind(this);
this.handleUsernameChange = this.handleUsernameChange.bind(this);
this.handlePasswordChange = this.handlePasswordChange.bind(this);
}
componentWillUpdate(nextProps) {
if (this.props.authenticated !== nextProps.authenticated) {
if (nextProps.authenticated) {
console.log('true?', nextProps.authenticated)
return (
<Redirect to="/page1" />
);
}
}
}
handleSubmit(e) {
e.preventDefault();
this.props.userSignin({ username: this.state.username, password: this.state.password });
this.setState({ username: '', password: '' });
}
.....
render() {
return (
<form onSubmit={this.handleSubmit}>
<input
placeholder="username"
value={this.state.username}
onChange={this.handleUsernameChange}
/>
<input
placeholder="password"
type="password"
value={this.state.password}
onChange={this.handlePasswordChange}
/>
<span>
<button type="submit">SIGNIN</button>
</span>
{this.renderError()}
</form>
);
}
}
function mapStateToProps(state) {
return {
authenticated: state.auth.authenticated,
errMsg: state.auth.err
};
}
function mapDispatchToProps(dispatch) {
return {
userSignin: ({ username, password }) => dispatch(userSignin({ username, password }))
};
}
export default connect(mapStateToProps, mapDispatchToProps)(Signin);
在这段代码中,这确实记录了true?,但它不会重定向到/page1。
正如我所提到的,这是我第一次使用 react-router-dom 库,对于我在代码中出现的任何愚蠢错误,我深表歉意。
谢谢你,请了解我!
【问题讨论】:
-
你说它不会重定向到
/page1路由。那它去哪儿了? -
它停留在
/路由中。 -
Ok... 尝试将
exact path用于您的/路由,因为这将匹配所有其他路由。让我知道这是否有效,以便我可以将其添加到答案中。<Route exact path="/" component={App}/><Route exact path="/" component={Signin}/>
